Angiographic evaluation of machine perfused kidneys

Area of Science:

• Nephrology
• Transplant Surgery
• Medical Imaging

Background:

• A functional renal vascular system is crucial for successful kidney transplantation and machine preservation.
• Current viability tests often overlook vascular integrity, focusing primarily on cellular health.
• Undetected vascular pathology can compromise graft function post-transplantation.

Purpose of the Study:

• To evaluate the utility of angiography during machine preservation for assessing renal vascular status.
• To determine if angiography can detect occult vascular lesions and assess perfusion patterns.
• To explore the role of angiography in conjunction with cellular viability tests for borderline kidney evaluation.

Main Methods:

• Angiography performed during the machine preservation of kidneys.
• Assessment of renal vascular system for alterations, vasoconstriction, and perfusion patterns.
• Comparison of angiographic findings with cellular viability assessments.

Main Results:

• Angiography is a simple, safe, and reliable method for examining the renal vascular system during preservation.
• The technique effectively demonstrates the degree and reversibility of vasoconstriction.
• Angiography identifies both normal and pathological perfusion patterns, revealing occult vascular pathology.

Conclusions:

• Angiography during machine preservation provides critical information on vascular integrity.
• This method complements cellular viability tests by assessing vascular health.
• Angiography can aid in the pre-transplant evaluation of borderline kidneys by identifying vascular suitability.
