Abstract:

BACKGROUND: Interventional therapy for vascular complications after allograft kidney transplantation has become a safe and effective treatment.
OBJECTIVE: To explore the diagnosis experiences and value evaluation of interventional treatment for vascular complications after allograft kidney transplantation.
METHODS: The clinical data of eight patients with interventional treatment for vascular complications after allograft kidney transplantation were retrospectively studied.
RESULTS AND CONCLUSION: In the eight cases undergoing transplantation, five cases were found renal artery stenosis, two cases were found pseudoaneurysm, and one case was found renal vein thrombosis, and they were all diagnosed by color Doppler flow imaging. Five cases of renal artery stenosis took further examination by magnetic resonance angiography, and they underwent ballon angioplasty and followed-up for 6, 8, 20, 36 and 40 months. One case was found restenosis in five cases, whose serum creatinine level maintained in the range of 130-160 μmol/L. Four cases of renal artery stenosis in five cases were found no recurrence, and their serum creatinine level was in normal range. The aneurism in two cases of renal artery pseudoaneurysm disappeared after undergoing stent graft placement across the external iliac artery, and then they were treated with routine hemodialysis. Thrombosis disappeared in one case of renal vein thrombosis after undergoing interventional thrombolysis. The graft function recovery of this case delayed, the serum creatinine level decreased to 210 μmol/L at day 35. After that the serum creatinine level of this case maintained in the range of 200-250 μmol/L. Based on the clinical data of these eight cases, it suggests that interventional treatment for vascular complications after allograft kidney transplantation is feasible.
