[Vascular complications in kidney transplant patients]

ABSTRACT

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. 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. 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. 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. 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
