Abstract
Transplant renal artery stenosis is the most frequent vascular complication of transplantation. Early detection and correction reduce patients' morbidity and allograft dysfunction. Although noninvasive imaging can detect an underlying stenosis, angiography with subsequent angioplasty or stenting, or both, provides definitive diagnosis and treatment. With the introduction of alternative contrast agents and newer catheter and stent technology, these procedures can be performed safely with little risk of contrast-induced nephropathy or allograft loss.
摘要
移植肾动脉狭窄是移植最常见的血管并发症。早期检测和纠正可降低患者的发病率和移植肾功能障碍。虽然非侵入性成像可以检测潜在的狭窄，但血管造影及随后的血管成形术或支架置入术，或两者兼施，可提供明确的诊断和治疗。随着新型造影剂以及更新的导管和支架技术的引入，这些操作可以安全地进行，对比剂诱发的肾病或移植肾丢失风险很小。
