A Case of Anastomotic Stenosis of a Peripheral Arterial Bypass Graft Undetected in Indocyanine Green Angiography

Abstract

We report the case of a 75-year-old man who underwent right femoral-popliteal bypass surgery. Anastomotic stenosis was overlooked in indocyanine green (ICG) angiography due to opacification on the bypass graft. X-ray angiography revealed slit-shaped stenosis in the distal graft anastomosis that required revision. Although blood flow may be maintained despite of anastomotic stenosis, small decreases in blood flow cannot be detected in ICG angiography. We describe and discuss the pitfalls of qualitative graft assessment using ICG angiography, and compare ICG fluorescence luminance intensity between primary and revised grafts.

Anastomotic stenosis of a reconstructed dissecting superior mesenteric artery aneurysm undetectable by intraoperative indocyanine green angiography: A case report

“… 1 , 2 , 3 However, although ICG angiography can confirm the presence or absence of blood flow, detailed evaluation of the anastomotic morphology is sometimes difficult. 4 , 5 In the present study, we report a case in which intraoperative ICG angiography failed to identify anastomotic stenosis during reconstruction in a patient with a dissecting superior mesenteric artery aneurysm (dSMAA).…”
