OBJECTIVE: The purpose of this study was to assess the pelvic circulation during endovascular abdominal aortic aneurysm repair (EVAR) with a new monitoring system measuring penile and buttock blood flow. METHODS: We measured penile brachial pressure index (PBI) during EVAR by pulse-volume-plethysmography (form PWV/ABItrade mark). We also measured bilateral gluteal tissue oxygen metabolism with near-infrared spectroscopy to provide a gluteal tissue oxygenation index (TOI). Twenty-two men who underwent aortouni-iliac stentgraft with crossover bypass for exclusion of abdominal aortic aneurysm were studied. Twelve patients underwent aorto-uni-common iliac artery stentgraft (CIA) and ten underwent aorto-uni-external iliac artery stentgraft (EIA). RESULTS: In all patients, there was an immediate reduction in PBI during the EVAR procedure. After revascularization of the ipsilateral limb of the stent graft, the recovery of PBI was significantly less in EIA group. After the completion of crossover bypass, PBI in both groups recovered to the baseline values. In both groups there was a bilateral reduction in gluteal TOI during malperfusion of the internal iliac artery. After revascularization of ipsilateral limb of the stent graft, the ipsilateral TOI recovered to the baseline level in CIA patients, but recovery was incomplete in EIA patients. In contrast, contra-lateral TOI remained low in both groups after revascularization of ipsilateral limb of the stent graft. Only after completion of crossover bypass did the contra-lateral TOI recover to baseline level in both groups. CONCLUSIONS: Both TOI at the buttocks and PBI are a sensitive reflection of pelvic haemodynamics. Penile blood flow and bilateral gluteal blood flow are supplied via different circulations and both should be monitored for full assessment of the pelvic circulation. |
