10. GUIDE WIRES
• Control and permits access to vasculature
• have the characteristics of pushability and flexibility
–Pushability : characteristics associated with the direct
transfer of forces on the wire from manipulations outside
the patient’s body as they translate to forward advancement
of the wire or device inside the patient.
–Flexibility is a characteristic that usually works in a manner
counter to pushability. The more stiff a wire, or the less
flexible it is, the more pushable it will be

which current endovascular platforms are based
• 0.035-inch : . For most angiographic procedures and most
aortoiliac interventions
• 0.018-inch and 0.014-inch : : infrageniculate lesions or tight renal
and carotid stenoses
• 0.038-inch wire for passage of a large-diameter sheath or delivery
of an endograft through a tortuous iliac artery

15. GUIDE WIRES : Tips
Floppy-tip or J tip : no inner
core in its tip and flexible,
reduces the potential for
endoluminal injury by buckling
when it encounters resistance.
Curved or angled : for
selective cannulation and may
be steered into a desired
location.
Grant, L. A. and N. Griffin (2013). Grainger & Allison's Diagnostic Radiology Essentials E-Book, Elsevier Health Sciences.
16. Steerable
• Hydrophilic guidewires (Terumo, Roadrunner): good torque control ,
have a hydrophilic coating and must be kept wet – their frictionless nature
allows them to cross narrow stenoses
Non-steerable : allows the catheter to be advanced into position
• 3mm J guidewire: this has a 3mm radius to its distal curve – 5, 10
and 15mm curves are also available
• Bentson wire: this has a very floppy atraumatic tip
• Amplatz super stiff: this is a very strong wire to provide support for
introducing stents

Grant, L. A. and N. Griffin (2013). Grainger & Allison's Diagnostic Radiology Essentials E-Book, Elsevier Health Sciences.
23. GUIDE CATHETERS
• Introduced to help direct devices and wires to distal locations
• Inject contrast material distally
• Provide support to keep a vessel ostium engaged
• Intended to be placed through access sheaths and into the
target vessel.
24. DIAGNOSTIC CATHETERS
• Aid in target vessel selection
• Catheters may have hydrophilic coatings, radiopaque tips, or marker
bands and have braiding to increase pushability and kink resistance
• peripheral indications range from 4F to 6F and typically
have inner diameters of 0.035 or 0.038 inch.
• Microcatheters are small 2F to 3F catheters that can be advanced through
the lumen of standard diagnostic catheters for superselective
cannulation of smaller vessels
26. Nonselective Catheters
• Or “flush” catheters are used for aortic and vena cava injections or injections where
displacement of a large volume of blood with contrast material is necessary to fill
the entire lumen
• The catheter has an endhole and multiple, much smaller sideholes extending down
onto the distal 1–2 cm of the shaft.
• The distribution of sideholes produces a homogeneous contrast bolus
27.
28. • Selective catheters are end-hole catheters with tips in a variety of
shapes to facilitate vessel cannulation
• Power injection settings must be adjusted when end-hole catheters
are used in smaller vessels to avoid intimal injury by uplifting plaque
SELECTIVE CATHETERS
31. • These are typically straight and tend to have more
body or
stiffness to allow pushability in crossing vessel
stenoses or
total occlusions.
• They also can come with single curves at the
end to aid in directing the wire.
Crossing Catheters
32.
33. Access : Principle
1. Choose the puncture site with the individual patient’s needs in mind.
2. Determine the likelihood of performing an endovascular intervention during the
angiogram procedure and take that into account when choosing a puncture
site.
3. Pick the access site that is far enough from the lesion so that a sheath may be
placed without encountering the lesion itself.
4. Feel the artery intended for puncture so you know what to expect. Is it soft or
hard and what is the quality of the pulse?
5. Palpate the anatomic landmarks
6. Visualize the artery and its relationship to anatomic landmarks before skin
puncture.
Schneider, Peter. Endovascular Skills: Guidewire and Catheter Skills for Endovascular Surgery, Third Edition (Kindle Locations 578-591). CRC Press. Kindle Edition.
34. 7. Standardize your technique.
8. Use fluoroscopy for guidance.
9. Do not be afraid to abandon the access and puncture elsewhere if the
risk is too high.
10. No one gets in every single time.
11. If there is a problem, hold pressure for a few minutes and start again.
12. It is rare to have any significant damage to the access artery from the
needle alone. Larger problems occur when a poor puncture placement is
not recognized and larger devices are placed through that site.

• The most common : The common femoral artery (CFA)
• Alternative sites include : axillary artery, brachial and radial
artery access
• Alternative access for infrageniculate interventions can be
distally through the popliteal arteries or tibial arteries
• when other access sites are not available : Carotid and
subclavian artery two sites are associated with a higher risk of
hemorrhage

approach
With the arm abducted 60 to 90 degrees, the pulse is palpated in the antecubital fossa and access is obtained
just proximal to the crease of the elbow
Kessel, D. and I. Robertson (2016). Interventional Radiology: A Survival Guide E-Book, Elsevier Health Sciences.
47. The arm needs to be abducted at 90 degrees and externally rotated, with a towel roll placed under the
axilla. Alternatively, the axillary region may be exposed by flexing the arm at the elbow and placing the
hand behind or just above the head. A micropuncture needle access kit is recommended for access.
Axillary Artery approach

51. Procedure
• Adequately anaesthesia
• 5–10 mL of 0.5–1% lidocaine is infltrated around the artery. if the
puncture site is inadequately anaesthetised arterial spasm and
make selective catheterisation very difficult
• Small scalpel incision is made in the skin
• Ultrasound is also recommended to help select the
most appropriate site of puncture, avoiding atherosclerotic
plaques, and is also used to guide needle entry.

Used particularly to navigate strictures and avoid branch vessels
Cronenwett, J. L. and K. W. Johnston (2014). Rutherford's Vascular Surgery E-Book, Elsevier Health Sciences.
58. Closure technique
• Manual Compression
Venous punctures require 5 to 10 minutes
Arterial puncture : This compression should not require total
occlusion of distal flow. When possible, simultaneous palpation of the
pulse distal to the compression location is recommended.
a general guideline of 3 minutes per French size has been used.
Typically, manual pressure will not reliably obtain hemostasis for
sheaths larger than 8F.

59. Closure Devices
• The devices can be divided into groups as
Intravascular and extravascular plugs
Suture mediated/mechanical
Compressive assistance.

66. These devices are
placed over the puncture site
and adjusted with a

by pressure bag inflation
Compressive Assistance
Femostop

69. • Groin haematoma : minimized by adequate post-procedure
puncture site compression
• False aneurysm formation: inadequate haemostasis and is more
likely to occur with a low CFA puncture where the artery
cannot be compressed against the femoral head ▶ the treatment
options include US-guided compression, thrombin injection and
surgical repair
• Arteriovenous fistula formation: this is uncommon with a CFA
puncture but is more likely with a SFA puncture (as the femoral vein
lies deep to it)
Local Complication
Grant, L. A. and N. Griffin (2013). Grainger & Allison's Diagnostic Radiology Essentials E-Book, Elsevier Health Sciences.
70. • Thrombosis: this is more likely if the artery is severely diseased at the
puncture site
• Arterial dissection : this usually occurs with an antegrade approach ▶
retrograde dissections are usually self-limiting
• Distal microembolization: this follows thrombus or
atheroma breaking off from the vessel wall

71. Conclusion
Access : most common site : Rt. CFA
Needle : Single wall > Double wall
Sheath and catheter size
CFA : 5-6 Fr
Brachial : 5-6 Fr
Hydrophilic guidewire : MC diameter 0.035-inch
Length 50–80 cm : Retrograde femoral catheterization
for ipsilateral femoral arteriogram
145–150 cm : General arteriography and
antegrade approach to infrainguinal arteries
180 – 210 cm : contralateral infrainguinal
interventions, subclavian interventions
And Closure Techniques : Compression 3 minutes per
French size
Fixed mount imaging suite or hybrid room
Mobile C-arm portanle
components includea 21-gauge needle, a 0.018-inch wire, and a microintroducer sheath
The most common sizes for vascular access needles are 18- to 21-gauge in diameter and 2¼-5 inches in length.
A : single wall : needle tip placed into anterior wall of the artery
B : Double wall has a trochar and sharp bevel tips that inserted through the artery then needle is removed and withdrawn the blunt tip seen tip in arteral lumen by
pulsatile backbleeding
Double-wall puncture needles are not widely used because of the unnecessary posterior wall vessel puncture
Guidewire length is chosen based on the sum of the distance from the site of vascular entry to the site of intervention and the device platform, such as an over-the-wire or monorail system
an angiogram can be obtained over a diagnostic catheter alone, without use of a sheath, tokeep the arteriotomy site smaller
Sheaths are sized by the inner diameter wall to wall in French
Thus, A typical thin walled 5f sheath has an approximately 6Fr outer diameter, AND CAN takes a 5Fr catheter
Diagnostic catheters fall into three categories:nonselective, selective, and crossing
best arterial access sites should have a bone or bone prominence beneath the artery against which pressure can be applied on completion
when other access sites are not available : Carotid and subclavian artery two sites are associated with a higher risk of hemorrhage because of the inability to adequately compress the access site when the catheters or sheaths areremoved
femoral artery begins at the inguinal ligament and lies underneath it in the medial third The pulse palpable just under the inguinal ligament (ASIS to pubic tubercle) should be the CFA.
Femoral artery localization. Right anterior oblique angiogram demonstrates the correct zone of entry of the commonfemoral artery. The access should be below the epigastric branches and above the profunda femoris artery, between the oblique lines.
Retrograde femoral access : The goal is to puncture the proximal to middle CFA
Antegrade femoral access : infrageniculate intervention
the prone position directly behind the patella with ultrasound guidance.
It is important to remember that the popliteal vein is commonly duplicated in this position to avoid errors in identifcation.
In conjunction with a second access site with the patient in a supine position, the popliteal artery can be accessed by flexing the knee and externally rotating the hip.
Percutaneous catheterisation. One of the commonly used techniques of percutaneous arterial catheterisation.The artery (1) is transfxed (2). The needle is partially withdrawn and re-angled
(3). A guidewire is passed into the needle during free backflow of blood (3, 4), the needle is removed and a catheter or introducer is inserted over the wire (5, 6). When the catheter is safely within the arterial lumen, the wire is withdrawn (7).
Access selection + inserted sheath and hydrophilic wire
And after that we choose diagnostic catheter and manipulating a catheter under fluoroscopic control for Selective catheterisation
Each catheter shapes are suitable for catheterising certain arterial branches
Roadmap (subtracted fluoroscopy) In this mode, a subtracted fluoroscopic image isobtained after a few seconds of fluoroscopy. Contrast is injected to opacify the vessels, andfluoroscopy stopped. The next time screening is activated, the catheter and guidewire will beseen superimposed on the subtracted image of the blood vessels (Fig. 29.1B and also can show that angioplasty balloons are correctly sized (Fig. 29.1C).
Angio-Seal : mechanical seal by sandwiching the arteriotomy between a bioabsorbable anchor and a collagen sponge, which dissolve within 60 to 90 days.
Should not be used in small arteries (<5 mm) or arteries with signifcant occlusive disease The device comes in 6F and 8F versions.
