肾动脉狭窄是肾移植最常见的血管并发症,发病率为1～25%,病因包括受体动脉硬化、肾灌洗时肾动脉损伤、错误的血管吻合及肾动脉纽转的受压,但免疫学因素未引起足够重视。作者对4年间连续100例肾移植进行回顾性分析,供肾采用整块原位Collins,液灌洗法并置于右髂窝。9例随访表明继发性高血压或原有高血压恶化(降压治疗无效),该9例(Ⅰ组)与年龄和术后时间类似的40例(Ⅱ组)作对照,并比较两组供者年龄,HLA配型程度,急、慢性排斥发病率和肾功能,同时分析了Ⅰ组血管杂音,狭窄的类型、位置、发病时间以及肾动脉狭窄成形术(8例经皮经管腔血管成形术,1例手术切除狭窄血管段后再吻合)后对血压肾功能恢复的效
Renal artery stenosis is the most common vascular complication of renal transplantation, the incidence rate of 1 ~ 25%, the causes include atherosclerosis of the recipient, renal artery injury during renal lavage, wrong vascular anastomosis, Immunological factors have not attracted enough attention. The authors conducted a retrospective analysis of 100 consecutive cases of kidney transplantation over a 4-year period. The kidneys were treated with whole-body Collins in situ and lavage in the right iliac fossa. The follow-up of 9 cases showed that secondary hypertension or exacerbation of hypertension was invalid (antihypertensive treatment was invalid), and the other 9 cases (group Ⅰ) were compared with 40 cases (group Ⅱ) with similar age and postoperative time Donor age, degree of HLA matching, incidence of acute and chronic rejection, and renal function. The incidence of vascular murmur, type of stenosis, location, onset time and renal artery stenosis in group Ⅰ (8 percutaneous transluminal vessels Angioplasty, 1 case of surgical resection of the stenotic segment before anastomosis) on the recovery of blood pressure and renal function
