Why is CT Pelvis Vessel Study Needed Before Kidney Transplant?

 Purpose:

To evaluate the pelvic blood vessels (especially iliac arteries and veins) for suitability for attaching the donor kidney during transplantation.

Key Structures Evaluated in CT Pelvis Vascular Study:

🔸 Arterial Evaluation:

• Common iliac arteries

• External iliac arteries

• Check for:

  • Calcifications

  • Atherosclerosis

  • Narrowing (stenosis)

  • Aneurysms

🔸 Venous Evaluation:

• Common iliac veins

• External iliac veins

• Look for:

  • Thrombosis

  • Compression

  • Congenital anomalies

How It’s Done (Protocol Overview):

CT Angiography (CTA Abdomen + Pelvis)

• Contrast: IV contrast (non-ionic)

• Phases:

  1. Arterial Phase – to assess arteries clearly

  2. Venous Phase – optional, to check veins

• Coverage: From diaphragm to pubic symphysis

• Reconstruction: Thin slices, MIP, 3D for surgical planning

Why It’s Crucial for Kidney Transplant:

• The donor kidney's artery and vein must be connected to recipient’s iliac artery and vein.

• CT shows if the vessels are patent and suitable for anastomosis.

• Avoids surgical surprises like heavily calcified or occluded arteries.

• Helps choose the side (right or left) for kidney placement.

 Typical Report Includes:

• Vessel patency (open or blocked)

• Degree of atherosclerosis

• Vessel diameter

• Anatomical variations

• Presence of stenosis, thrombus, aneurysms
