| Summary: | Introduction: The superiority of indocyanine green fluorescence angiography (ICG-FA) to the clinical eye alone to assess tissue perfusion has been demonstrated in various surgical fields. This short report demonstrates the in vivo use of ICG-FA to assess skin perfusion before ligating the external iliac artery (EIA) to exclude a common femoral artery (CFA) aneurysm. Report: A 70-year-old man presented with a CFA aneurysm after a previous transfemoral amputation. Ligation of the EIA was proposed, but concerns about tissue perfusion warranted a careful approach. The CFA was exposed using an infra-inguinal incision. Intra-operative ICG inflow and washout patterns were semi-quantitatively analysed to assess dermal perfusion of the femoral stump before and after EIA clamping. Based on similar patterns, distal EIA ligation was performed without ischaemic complications. Conclusion: Indocyanine green fluorescence angiography is a promising technique for in vivo assessment of tissue perfusion in peripheral arterial disease, but standardised protocols for perfusion quantification are required to more accurately predict tissue viability. |
