Abstract：
Transplant renal artery stenosis (TRAS) represents a significant vascular complication subsequent to renal transplantation. This pathology is associated with grave implications including graft dysfunction and mortality. Early identification and therapeutical intervention are imperative for preserving graft longevity and achieving optimal clinical outcomes. We detail the case of a male in his 20s, following renal transplantation, who encountered recurrent TRAS, aetiologically linked to mechanical arterial kinking. Initial management using endovascular techniques yielded insufficient resolution. Consequently, the persistence of endovascular-resistant stenosis necessitated a surgical bypass intervention using the great saphenous vein, granting a 2-year period devoid of restenosis. The existing literature emphasises the indispensability of discerning the appropriate juncture for transitioning from endovascular to surgical management in TRAS cases. The robustness and durability of bypass grafts present an efficacious therapeutical strategy in contemporaneous practice.
摘要：
移植肾动脉狭窄（TRAS）是肾移植后的严重血管并发症。这种病理与包括移植物功能障碍和死亡率在内的严重影响有关。早期识别和治疗干预对于保持移植物寿命和实现最佳临床结果至关重要。我们详述了一个20多岁的男性的案例，肾移植后，遇到反复的TRAS，病因学上与机械动脉扭结有关。使用血管内技术的初始管理产生的分辨率不足。因此,血管内抵抗性狭窄的持续存在需要使用大隐静脉进行手术旁路干预，给予2年无再狭窄的期限。现有文献强调了在TRAS病例中辨别从血管内过渡到手术管理的适当接合点的必要性。旁路移植物的坚固性和耐久性在同期实践中提出了有效的治疗策略。
