Background & Objective: vascular complications are impotent after kidney Transplantation, They influence on patient and graft survival . There are a lot of factors that play are a role in incidence of these vascular compilations as technical and anatomical ones . Aim of study : the aim is to determine the incidence of vascular complications in kidney transplant patients in addition to signs and symptoms related to these complications, diagnosis modalities, management and results. Materials & Methods: A retrospective study, including 288 kidney transplant patients , has been performed in Kidney Transplantation Unit in Al-Mouassat University Hospital, from January 2007 until December 2009, all of them are from living donors (relative and non-relative) . Duplex Doppler Ultrasound has been performed routinely one week postoperatively for all patients . In certain cases we performed Ultrasound when signs and symptoms indicated to vascular problems. Results: five cases of renal artery thrombosis (1,7 % of patients), four cases of renal vien thrombosis (1,3 % of patients), 7 cases of renal artery stenosis (2,4 % of patients), The management includes PTA (percutaneous transluminal angioplasty), revision of amastomosis, renal venotomy or arteriotomy and removal of clot, and graft nephrectomy . Conclusion: the incidence of vascular complications in this study is less than that of most international studies, may be the cause is that we use only living donors, not cadaveric ones . The only diagnosis modality is duplex Doppler Ultrasound, we didn’t use MRA (Magnetic Resonance Angiogram) or multislices CT. Early surgical exploration may be a salvage procedure leading to management of vascular problem and prevention of graft toss.
