About two-thirds of the autotransplants were performed before percutaneous transluminal angioplasty (PTA) was established for clinical use. However, vascular disease at a site or type not suitable for PTA was present in 57 (90%) of the kidneys. Hypertension was the leading symptom in 56 patients, including four in whom renal autotransplantation was performed as an emergency for acute renal artery occlusion or malignant hypertension. Blood pressure returned to normal or improved in 51 (91%) and remained unchanged in five patients (9%) following autotransplantation. Three patients with renal artery aneurysm in whom haematuria and loin pain were the indications for treatment, became asymptomatic following surgical intervention. Bilateral renal autotransplantation was performed synchronously in one and sequentially in three patients. There were no operative deaths, but two kidneys were lost postoperatively in two 2-year-old children owing to renal vascular thrombosis. In the follow-up period (mean 4.3 years), one additional kidney was lost at 3 months owing to progressive FMD. Blood pressure and renal function remained stable in all other patients. Based on the excellent results achieved in this series, it is concluded that extracorporeal vascular repair and renal autotransplantation is a safe procedure for the patient as well as the kidney affected by FMD. The procedure is advocated as an alternative to in situ reconstruction in patients with renal artery disease not accessible to PTA, such as aneurysms and complex branch renal artery stenoses. | lld:pubmed |
