We present 2 cases of individuals with primary ischemic vascular disease of the BS who evolved to BD and were donors of solid organs and tissues. In both cases, the clinical examination was positive for the diagnosis of BD, and transcranial Doppler did not confirm the pattern of cerebral circulatory arrest that accompanies BD. The magnetic resonance angiography performed on 1 patient confirmed the lesion etiology and the presence of vascular obstruction. Both patients were real and effective organ and tissue donors. In these cases, we suggest not to resort to transcranial Doppler as an auxiliary diagnostic test. BACKGROUND Intraoperative temporary portocaval shunt (TPCS) has been performed during liver transplant to improve hemodynamics and renal function as well as to decrease bleeding during hepatectomy. The aim of this study was to evaluate the impact of TPCS on liver transplant in a long-term single-center study. METHODS From January 2006 to December 2018, all deceased donor transplants were retrospectively evaluated. Patients were divided in 2 groups group 1, including those in whom intraoperative TPCS was performed and group 2, including those without TPCS. We analyzed recipient characteristics, survival, mortality, and complication rates in the intraoperative and postoperative periods. RESULTS A total of 999 deceased donor liver transplants were studied, with 509 patients in group 1 and 490 in group 2. There were 156 cases (15.61%) of preoperative portal vein thrombosis in the whole series. Postoperative renal function (P = .029) as well as length of hospital and intensive care unit stay (P = .0001) were better in group 1. Surgery time and warm ischemia time was also shorter in group 1 (P = .0001). Complications with Clavien-Dindo score ≥ 3 were h
