RESUMO
OBJECTIVE: Vascular invasion is no longer considered to be an absolute contraindication to tumor removal, and complex reconstructions are part of the daily activity of vascular surgeons in specialized cancer centers. Our aim was to report a single-center experience of complex vascular reconstructions involving en bloc resection of tumors and patients' long-term survival and graft patency outcomes. To the best of our knowledge, this is the largest report of vascular reconstructions published to date, with the longest follow-up. METHODS: Between September 1997 and January 2016, there were 91 patients who underwent 92 arterial and 47 venous reconstruction procedures in this retrospective cohort study. Long-term survival and patency outcomes were analyzed for all study patients and individually assessed in different body segments (head and neck, thorax, upper limbs, abdomen, and lower limbs). RESULTS: The estimated mean and median follow-up times were 112.66 and 100 months, respectively. The 24- and 60-month survival estimates for the patients overall were 55.3% and 31.1%, respectively. Survival estimates were significantly lower in the head and neck cases compared with the other body segments. The primary arterial patency rates at 24 and 60 months were 96.7% and 84.9%, respectively, and they were similar in all body segments. The venous patency rates were 71.4% and 64.2% at 24 and 60 months, respectively. Seven cases (7.6%) of arterial vascular complications were observed. CONCLUSIONS: Vascular reconstruction performed in conjunction with oncologic resection is a feasible treatment option for tumors with vessel involvement. When surgery is performed in specialized centers, low perioperative morbidity and long-term patency rates are expected irrespective of the vascular territory undergoing intervention.
