Cannulation for ECMO
SURGEON’S PERSPECTIVE
- Dr. ChaitanyaChittimuri
MS, MCh (AIIMS, New Delhi)
ECMO
PERIPHERAL
VA VV
CENTRAL
Central ECMO cannulation
• Involves sternotomy
• Direct surgical cannulation of
the right atrium and aorta.
• Operating theatre
When ?
• First-choice modality for
cardiorespiratory support
• upgrade from peripheral
configuration
• LV distention and differential hypoxia
of the heart or the brain.
Central ECMO cannulation
Advantages:
• Excellent venous drainage
• reliable arterial return
• antegrade fashion
• left ventricular decompression
• size of the cannulae : body surface area
• aortic cannulation 22–24 Fr,
• venous cannulation (two stage cannula) 32–34 to 40–46 Fr
• calculated full flow delivery
Central ECMO cannulation
Disadvantages:
• Sternotomy related issues - bleeding, infection, resternotomy
• Aortic dissection
• Difficulty to mobilize the patient
• Ischaemic events of embolic origin
• Bleeding from cannulation site or their displacement -
purse string, snuggers, spigots, fixing the cannulae to the chest wall from within the chest cavity,
Hollister anchors
Peripheral VA-ECMO
Central ECMO cannulation
• Involves sternotomy
• Direct surgical cannulation of
the right atrium and aorta.
• Operating theatre
When ?
• First-choice modality for
cardiorespiratory support
• Upgrade from peripheral
configuration
• LV distention and differential hypoxia
of the heart or the brain.
Peripheral ECMO cannulation
When ?
• Refractory cardiogenic shock (myocardial
infarction, fulminant myocarditis,
decompensated chronic heart failure,
peripartum cardiomyopathy),
• Bridge (to durable LVAD or transplantation)
• Part of resuscitation
Flow rates are more often limited by the size
of the venous (inflow) drainage cannula than
the arterial (outflow) cannula
The size of the cannula depends on calibre of
the vessels
Fr=D (mm) ×3
Sites for ECMO cannulation
Peripheral ECMO cannulation
Peripheral ecmo
cannulation
percutaneous
Seldinger
technique
open cutdown
open cutdown
Seldinger (“semi
Seldinger”)
open cutdown

graft (Dacron)
Femoral cannulation
Axillary artery cannulation
Issues with peripheral arterial cannulation
• Recirculation of blood
• Limb ischaemia.
• Retrograde flow creates additional afterload to LV
• Retrograde flow competing with native circulation generated by the heart.
• Recirculation of blood
Issues with peripheral arterial cannulation
Retrograde flow creates additional afterload to LV
• LV distension and interaction of blood flows from the heart i.e., not fully unloaded.
• end-diastolic pressures, reduced coronary flow, pulmonary oedema and subsequently hypoxaemia.
• depends on degree of impairment of LV,
• manifestation - absence of aortic valve opening, stasis of blood and potentially thrombus formation in
LV.
• pulsatility of the arterial trace confirming ejection of blood by LV
Issues with peripheral arterial cannulation
Options available to deal :
• Reducing afterload
• Optimizing vasopressor and inotropic support
• Optimal position of the venous cannula for best possible drainage
• Fluid offloading by diuretics or CVVH;
• IABP to reduce afterload
• more advanced option is to upgrade veno-arterial to veno-venous-arterial configuration of ECMO circuit
(VVA) inserting a second cannula for venous blood drainage (usually via internal jugular vein).
Issues with peripheral arterial cannulation
Retrograde flow competing with native circulation generated by the heart.
• Upper and lower parts of the body receive blood supply from different sources. watershed point
• Harlequin or North-South syndrome
• sampling from the right radial artery is warranted
• Options to overcome :
• adjusting ventilatory settings (FiO2, PEEP, recruitment manoeuvres);
• optimizing lung function (diuretics, draining effusion and so on);
• upgrading the circuit to eitherVVA ECMO
ThankYou
