The aim of this study was to document vascular complications that occurred following cadaveric and living donor kidney transplants in order to assess the overall incidence of these complications at our center as well as to identify possible risk factors. In a retrospective cohort study, 1500 consecutive renal transplant recipients who received a living or cadaveric donor kidney between December 1988 and July 2006 were evaluated. The study was performed at the Nemazee Hospital, Shiraz, Iran. The assessment of the anatomy and number of renal arteries as well as the incidence of vascular complications was made by color doppler ultrasonography, angiography, and/or surgical exploration. Clinically apparent vascular complications were seen in 8.86% of all study patients (n = 133) with the most frequent being hemorrhage (n = 91; 6.1%) followed by allo-graft renal artery stenosis (n = 26; 1.7%), renal artery thrombosis (n = 9; 0.6%), and renal vein thrombosis (n = 7; 0.5%). Vascular complications were more frequent in recipients of cadaveric organs than recipients of allografts from living donors (12.5% vs. 7.97%; P= 0.017). The occurrence of vascular complications was significantly more frequent among recipients of renal allografts with multiple arteries when compared with recipients of kidneys with single artery (12.3% vs. 8.2%; P= 0.033). The same was true to venous complications as well (25.4% vs. 8.2%; P< 0.001). Our study shows that vascular complications were more frequent in allografts with multiple renal blood vessels. Also, the complications were much less frequent in recipients of living donor transplants.
本研究的目的是记录尸体供肾和活体供肾肾移植后发生的血管并发症，以评估这些并发症在我们中心的总体发生率，并确定可能的危险因素。在一项回顾性队列研究中，对1988年12月至2006年7月期间连续接受活体或尸体供肾的1500例肾移植受者进行了评估。该研究在伊朗设拉子的内马齐医院进行。通过彩色多普勒超声、血管造影和/或手术探查对肾动脉的解剖结构和数量以及血管并发症的发生率进行评估。在所有研究患者中，8.86%（n = 133）出现了临床明显的血管并发症，最常见的是出血（n = 91；6.1%），其次是移植肾动脉狭窄（n = 26；1.7%）、肾动脉血栓形成（n = 9；0.6%）和肾静脉血栓形成（n = 7；0.5%）。尸体器官受者的血管并发症比活体供肾移植受者更常见（12.5%对7.97%；P = 0.017）。与单动脉肾移植受者相比，多动脉肾移植受者血管并发症的发生率明显更高（12.3%对8.2%；P = 0.033）。静脉并发症也是如此（25.4%对8.2%；P < 0.001）。我们的研究表明，多肾血管移植中的血管并发症更常见。此外，活体供肾移植受者的并发症要少得多。
