Concept of Cavo-Pulmonary Shunt and the First
Experimental Studies
The right ventricular bypass was first successfully
achieved in 1949 by Rodbard and Wagner [1], who
worked at Michael Reese Hospital in Chicago. They
experimentally anastomosed the right atrial appendage
to the pulmonary artery and ligated the main pulmonary
artery and, thus, demonstrated the feasibility of the right
ventricular exclusion in chronic experiments on dogs.
  However, it was not until 1950, when the concept of
cavo-pulmonary shunt was first introduced by Italian
surgeon Carlo A. Carlon (Fig 1) and his colleagues [2, 3].
The story of cavo-pulmonary shunt begins on March 27,
1950, at the Second Clinical Congress of the Italian
Chapter of the International College of Surgeons held in
Padua and Venice, when three Italian surgeons, Carlon,
Mondini, and de Marchi, presented their experimental
study of cavo-pulmonary shunt. The results of their
experimental study on 8 dogs were first published in 1950
in Italian [2] and in 1951 in English [3]. It was Carlo A.
Carlon, Professor of Surgery at the University Medical
School in Padua, who first advocated that in certain
congenital heart defects an “advantage would be served

   It is unknown why more than a decade elapsed be-
tween their experimental studies of 1950s and 1964, when
Carlon reported their first clinical experience [4]. Because
their initial reports appeared in journals scarcely read by
most surgeons, the pioneering work of Carlon and his
colleagues soon fell into oblivion. Although today Carlon
is seldom given an appropriate credit, it was he who first
described the concept of the cavo-pulmonary shunt [5].
   It is our belief that the anastomosis between the right
pulmonary atery and azygos vein should be referred to as
Carlon’s technique. We are taking the liberty to do so
below.


The First Experimental Studies
After initial work of Carlon, the experiments on cavo-
pulmonary shunts continued by independent groups in
Hungary, Russia, and USA.

Cavo-Pulmonary Shunt via Azygos Vein—Carlon’s
Technique
In the 1954 volume of the Yale Journal of Biology and
Medicine, Glenn (Fig 3) and Patino published their first
experimental study on cavo-pulmonary shunts [6]. A
superior vena cava–right pulmonary artery shunt was
performed in 9 dogs using the azygos vein rather than by
direct caval anastomosis. The technique applied was very
similar to the technique described originally by Carlon.
The follow-up angiograms were done as late as postop-
erative day 13, and demonstrated patent anastomoses. In
1955 the Yale group reported a study of 59 operated dogs
with 6 long-term survivors [7]. Chylous pleural effusion          Fig 3. William Wallace Lumpkin Glenn (1914 –). Courtesy of

experimental end-to-end anastomoses of the superior
vena cava and the right pulmonary artery, and the next
year he applied the technique in 2 patients [11, 12]. Many
surgeons at that time continued to anastomose the right
atrial appendage to the pulmonary artery [11, 12]. In
April 1955, Hurwitt said: “. . . further investigation will be
necessary before one may state whether or not anasto-
mosis of the right auricular appendage to the pulmonary
artery may be beneficial in a case of tricuspid atresia. The
circulatory by-pass of the right heart described by Glenn
and Patino, anastomosing the azygos vein to the right
pulmonary artery, and the anastomoses between the
venae cavae and the pulmonary artery referred to by
Shumacker represent provocative experiments in this
direction” [12].
   It is often mentioned in surgical literature that the first
successful clinical cavo-pulmonary shunt was done and
reported in Russia. However, very little information is
available on what experimental studies preceded this
first success. Herein we describe this development in
more detail.
   In Russia, the idea of the cavo-pulmonary anastomosis
was first proposed in September 1955 by Nikolai K.
Galankin (1914 –1977) and the first experimental success
was achieved the same year by Tigran M. Darbinian (Fig
6). In his PhD thesis published on May 14, 1957, Darbin-            Fig 5. Harris B. Shumacker (1908 –). Courtesy of Dr Shumacker.

   the operation was performed on a number of patients by
   Vishnevsky and Galankin [13].

In Darbinian’s study, in 33 cases the anastomosis was
made end-to-end using Donetsky’s ring (Fig 7); in 13
cases, the anastomosis was made end-to-side and the
superior vena cava was side-clamped, in the same way
that was described by Glenn (Fig 8).
  On December 6, 1998, Darbinian told us a very inter-
esting story on how the research was started:
      I began my post-graduate training in the Vishnevsky’s
   Institute of Surgery in Moscow in 1954. My supervisor
   was Professor Nikolai K. Galankin. He had many patients
   with tricuspid atresia, but had no effective means of
   treatment. In 1955, he said to me: “Listen, why not to try
   cavo-pulmonary anastomosis on dogs?” He operated on 5
   dogs, I assisted him. All dogs died. It took ages to make
   the anastomosis. We did not make any shunting of blood
   and the pressure in the cross-clamped superior vena cava
   was as high as 600 mm of water during the anastomosing.
   Finally, he gave up, saying that nothing will come of it. He
   said to me: “Apparently, my idea is wrong, but do not get
   upset, I will soon invent something else.” He was, indeed,
   a very keen-witted man. Meanwhile, I made a good friend
   with Dr Donetsky. The latter headed the laboratory of
   blood vessel conservation. Donetsky showed me his ring            Fig 7. Donetsky’s ring. Technique of the end-to-side anastomosis
   and his technique to connect blood vessels, which took            using the stainless steel ring. (Reprinted from Donetsky DA. A new

      I rushed to Galankin and told him about my success
   and my conjecture. He was very happy but he has not
   operated since that moment, he just smiled and said:
   “Very well. Go ahead. This will be your PhD thesis.” I
   started to inject talc into the left pleural cavity and
   operated about 3 weeks after, so that adhesions could
   develop and prevent left lung collapse after the operation.
   All dogs survived.
      When I operated on 6 more dogs, Galankin wrote an
   article, with the meticulous description of the operative
   technique and angiographic findings of patent anastomo-
   ses, to the journal Eksperimentalnaja Khirurgia. The co-
   editor of the journal was Meshalkin at the Institute of
   Thoracic Surgery, and all manuscripts were submitted to
   him. In 4 months our manuscript was returned and the
   recommendation was given to at least double the number
   of operations. In the meantime Meshalkin performed 4
   clinical operations and presented them at the Moscow
   Surgical Society meeting. Later on our article of a total of
   13 experiments was published. After the initial clinical
   success of Meshalkin, the operation was performed fre-
   quently by Galankin at the Vishnevsky Institute of
   Surgery.

As early as 1951, Professor A. N. Bakulev, head of the
Institute of Thoracic Surgery in Moscow, had proposed
the idea of the cavo-pulmonary anastomosis [14, 15].

It seems timely, as we Glenn shunt today. The concept of cavo-pulmonary enter the new millennium, to give due credit to those shunting, however, was developed independently by individuals who put their minds and efforts into helping many surgeons. While the work of some of them is sick children. These people deserve recognition. widely recognized, the pioneering contributions of many others fall into oblivion.

Concept of Cavo-Pulmonary Shunt and the First Experimental Studies The right ventricular bypass was first successfully achieved in 1949 by Rodbard and Wagner [1], who worked at Michael Reese Hospital in Chicago. They experimentally anastomosed the right atrial appendage to the pulmonary artery and ligated the main pulmonary artery and, thus, demonstrated the feasibility of the right ventricular exclusion in chronic experiments on dogs. However, it was not until 1950, when the concept of cavo-pulmonary shunt was first introduced by Italian surgeon Carlo A. Carlon (Fig 1) and his colleagues [2, 3]. The story of cavo-pulmonary shunt begins on March 27, 1950, at the Second Clinical Congress of the Italian Chapter of the International College of Surgeons held in Padua and Venice, when three Italian surgeons, Carlon, Mondini, and de Marchi, presented their experimental study of cavo-pulmonary shunt. The results of their experimental study on 8 dogs were first published in 1950 in Italian [2] and in 1951 in English [3]. It was Carlo A. Carlon, Professor of Surgery at the University Medical School in Padua, who first advocated that in certain congenital heart defects an “advantage would be served Address reprint requests to Dr Konstantinov, Thoracic and Cardiovascu- Fig 1.

Subsequently, this complication also created problems in their clinical material [8]. On June 2, 1957, the Yale group reported an extensive study of 75 dogs. In all but 7 of these the anastomosis of the distal end of the divided right pulmonary artery to the side of the superior vena cava, utilizing the central stump of the divided azygos vein as an anastomotic channel, was made. In the re- maining 7 dogs, an end-to-end anastomosis was created central to the azygos vein [9]. The First Direct End-to-End Anastomosis of the Superior Vena Cava to the Right Pulmonary Artery In 1954 Francis Robicsek (Fig 4) and colleagues from the Department of Heart Surgery of the Post-Graduate Sur- gical Clinic in Budapest undertook an experimental study [9] and reported their initial results in the 1956 volume of Acta Medica Scandinavica [10]. In their study the direct vena cava-to-pulmonary artery anastomoses were done in about 15 minutes without cardiopulmonary by- pass [10]. In 1956 Robicsek moved to the USA and, being unaware of the work of Carlon, continued his experi- Fig 2.

Shumacker (Fig 5) performed a few It is unknown why more than a decade elapsed be- tween their experimental studies of 1950s and 1964, when Carlon reported their first clinical experience [4]. Because their initial reports appeared in journals scarcely read by most surgeons, the pioneering work of Carlon and his colleagues soon fell into oblivion. Although today Carlon is seldom given an appropriate credit, it was he who first described the concept of the cavo-pulmonary shunt [5]. It is our belief that the anastomosis between the right pulmonary atery and azygos vein should be referred to as Carlon’s technique. We are taking the liberty to do so below. The First Experimental Studies After initial work of Carlon, the experiments on cavo- pulmonary shunts continued by independent groups in Hungary, Russia, and USA. Cavo-Pulmonary Shunt via Azygos Vein—Carlon’s Technique In the 1954 volume of the Yale Journal of Biology and Medicine, Glenn (Fig 3) and Patino published their first experimental study on cavo-pulmonary shunts [6]. A superior vena cava–right pulmonary artery shunt was performed in 9 dogs using the azygos vein rather than by direct caval anastomosis. The technique applied was very similar to the technique described originally by Carlon. The follow-up angiograms were done as late as postop- erative day 13, and demonstrated patent anastomoses. In 1955 the Yale group reported a study of 59 operated dogs with 6 long-term survivors [7]. Chylous pleural effusion Fig 3. William Wallace Lumpkin Glenn (1914 –).

Many surgeons at that time continued to anastomose the right atrial appendage to the pulmonary artery [11, 12]. In April 1955, Hurwitt said: “. . . further investigation will be necessary before one may state whether or not anasto- mosis of the right auricular appendage to the pulmonary artery may be beneficial in a case of tricuspid atresia. The circulatory by-pass of the right heart described by Glenn and Patino, anastomosing the azygos vein to the right pulmonary artery, and the anastomoses between the venae cavae and the pulmonary artery referred to by Shumacker represent provocative experiments in this direction” [12]. It is often mentioned in surgical literature that the first successful clinical cavo-pulmonary shunt was done and reported in Russia. However, very little information is available on what experimental studies preceded this first success. Herein we describe this development in more detail. In Russia, the idea of the cavo-pulmonary anastomosis was first proposed in September 1955 by Nikolai K. Galankin (1914 –1977) and the first experimental success was achieved the same year by Tigran M. Darbinian (Fig 6). In his PhD thesis published on May 14, 1957, Darbin- Fig 5. Harris B. Shumacker (1908 –). Courtesy of Dr Shumacker. ian wrote: In September 1955, N.K. Galankin suggested and de- veloped in experiments on dogs a new operation— anastomosis between periferal end of superior vena cava and the right pulmonary artery. The operation was pro- posed for children with tetralogy of Fallot and tricuspid atresia. . . . In 1955, the anastomosis of the superior vena cava was performed by Shumacker in 2 children with pulmonary hypertension. The operations were not suc- cessful. In the beginning of 1956, Robicsek, Temesvari, and Kadar performed this operation in 15 dogs and recommended it for patients with decreased pulmonary flow. Thus, the anastomosis between superior vena cava and the right pulmonary artery was developed simulta- neously and independently by Galankin, Shumacker, and Robicsek. It is noteworthy that Shumacker performed this operation not for tetralogy of Fallot, but for transposition of great arteries and truncus arteriosus communis, both with pulmonary hypertension. In 1954, Glenn and Patino partially bypassed the right ventricle in 9 dogs by anastomosing the right pulmonary artery and the azygos vein with ligation of the superior vena cava below the anastomosis. . . . When we started our experiments, the works of Shumacker and Robicsek were not published yet. Since September, 1955 we performed 46 experiments on dogs. Of those we designed 34 chronic experiments to study the long-term effects of the anastomosis. Six dogs of those 34 died in the operating room, the rest of 28 survived and the long-term effects were studied. The maximal period of study was 1 year. Based on the idea of Galankin and our experiments on long-term hemodynamic evalution of the cavo-pulmo- nary anastomosis, Meshalkin successfully introduced this operation in clinical practice in 1956 for patients with Fig 4.

Once, without saying anything to Galankin, I took Donetsky with me and he assisted me on the sixth dog. The dog survived. I initially attributed it to the new technique; however, subsequently, when I started the long-term evaluation I noticed that this dog had previously been operated on the left side. The left lung was adherent to the chest wall and did not collapse. Dogs have very tiny pleural membranes in between pleural cavities and may easily develop left pneumothorax after the operation on the right. We drained only the right pleural cavity on the first 5 dogs, while the left lung was partially collapsed. The blood flow via the anastomosis was impeded due to increased pul- monary vascular resistance postoperatively, while the left lung was collapsed! Fig 6.

Courtesy of Dr Darbinian. the operation was performed on a number of patients by Vishnevsky and Galankin [13]. In Darbinian’s study, in 33 cases the anastomosis was made end-to-end using Donetsky’s ring (Fig 7); in 13 cases, the anastomosis was made end-to-side and the superior vena cava was side-clamped, in the same way that was described by Glenn (Fig 8). On December 6, 1998, Darbinian told us a very inter- esting story on how the research was started: I began my post-graduate training in the Vishnevsky’s Institute of Surgery in Moscow in 1954. My supervisor was Professor Nikolai K. Galankin. He had many patients with tricuspid atresia, but had no effective means of treatment. In 1955, he said to me: “Listen, why not to try cavo-pulmonary anastomosis on dogs?” He operated on 5 dogs, I assisted him. All dogs died. It took ages to make the anastomosis. We did not make any shunting of blood and the pressure in the cross-clamped superior vena cava was as high as 600 mm of water during the anastomosing. Finally, he gave up, saying that nothing will come of it. He said to me: “Apparently, my idea is wrong, but do not get upset, I will soon invent something else.” He was, indeed, a very keen-witted man. Meanwhile, I made a good friend with Dr Donetsky. The latter headed the laboratory of blood vessel conservation. Donetsky showed me his ring Fig 7. Donetsky’s ring.

    1104 HERITAGE KONSTANTINOV AND ALEXI-MESKISHVILI Ann Thorac Surg DEVELOPMENT OF THE CAVO-PULMONARY SHUNT 1999;68:1100 – 6 I rushed to Galankin and told him about my success and my conjecture. He was very happy but he has not operated since that moment, he just smiled and said: “Very well. Go ahead. This will be your PhD thesis.” I started to inject talc into the left pleural cavity and operated about 3 weeks after, so that adhesions could develop and prevent left lung collapse after the operation. All dogs survived. When I operated on 6 more dogs, Galankin wrote an article, with the meticulous description of the operative technique and angiographic findings of patent anastomo- ses, to the journal Eksperimentalnaja Khirurgia. The co- editor of the journal was Meshalkin at the Institute of Thoracic Surgery, and all manuscripts were submitted to him. In 4 months our manuscript was returned and the recommendation was given to at least double the number of operations. In the meantime Meshalkin performed 4 clinical operations and presented them at the Moscow Surgical Society meeting. Later on our article of a total of 13 experiments was published. After the initial clinical success of Meshalkin, the operation was performed fre- quently by Galankin at the Vishnevsky Institute of Surgery. As early as 1951, Professor A. N. Bakulev, head of the Institute of Thoracic Surgery in Moscow, had proposed the idea of the cavo-pulmonary anastomosis [14, 15]. However, it was not until successful experiments per- Fig 9.

The first articles on cavo- pulmonary shunt in Russian literature were published in 1956 by Galankin and Darbinian [16], soon followed by a clinical report of 24 cases by Evgenii N. Meshalkin (Fig 9) [14]. The First Clinical Application In the United States, the first to perform clinical cavo- pulmonary shunts was Harris B. Shumacker. On Novem- ber 15, 1954, at the Fortieth Annual Congress of the American College of Surgeons in Atlantic City, Shu- macker, discussing the article of Warden, mentioned the experiments in his laboratory, in which the “venae cavae were anastomosed directly to the pulmonary artery” [11, 12]. At the meeting, Shumacker also gave the first ac- count of the clinical application of the cavo-pulmonary shunt: “One was a very sick child who had truncus arteriousus with pulmonary hypertension and large pul- monary trunks coming off the common one. In this case and in one case with complete transposition, we simply performed a superior cava-right pulmonary artery end- to-end anastomosis” [11, 12]. Unfortunately, both chil- dren died 8 and 15 hours after the operation. The high pulmonary vascular resistance most likely contributed to Fig 8.

    Ann Thorac Surg HERITAGE KONSTANTINOV AND ALEXI-MESKISHVILI 1105 1999;68:1100 – 6 DEVELOPMENT OF THE CAVO-PULMONARY SHUNT shunting in Russia [21, 22]. Soon the final Russian tech- nique was established, and was used with some modifi- cations by most institutions in the Soviet Union. The anastomosis was created by four techniques: (1) using continuous U-shaped suture; (2) using interrupted single U-shape staples; (3) using Donetsky’s ring; and (4) using circular vascular stapler. The latter two methods had their disadvantages: although with Donetsky’s ring the diameter of the anastomosis was known precisely, it did not allow for normal growth; the circular vascular stapler required an extensive mobilization of the superior vena cava and necessitated the ligation of the azygos vein [23], although the azygos vein is ligated routinely by many surgeons today. On November 24, 1958, Bakulev and Kolesnikov submitted an article describing clinical expe- rience with 41 cases at the Institute of Thoracic Surgery in Moscow [15]. The first clinical report by Glenn [17] was published on July 17, 1958. In the report Glenn described a 7-year-old boy with transposition of the great vessels and decreased pul- monary blood flow who, on February 25, 1958, underwent cavo-pulmonary anastomosis (Fig 8). The child’s condition was improved significantly and an angiogram performed 2 months later demonstrated patent anastomosis. This was followed shortly by a successful operation Fig 10.
