“…The favourable outcome observed in technically successful PTA is in agreement with previously reported results (5,6,16). Blood pressure improved significantly in all patients, and, as a point of interest, remained so in 2 patients who developed chronic rejection during the follow-up period.…”

Ten patients with renal transplant artery stenosis were treated with percutaneous transluminal angioplasty (PTA). All patients suffered from hypertension refractory to drug treatment. PTA was successful in five patients. Blood pressure improved significantly and the antihypertensive medication could be reduced or withdrawn. Acute angulation at the anastomosis prevented successful PTA in four patients. One inaccessible stenosis was corrected surgically. No significant complications arose. If a renal transplant artery stenosis is haemodynamically significant, PTA should be considered the method of first choice for correction.

Angioplasty of renal transplant artery stenosis in children

et al. 1989

Systemic hypertension after renal transplantation in children is frequent, occurring in 85% of the cases and may be the cause of severe neurologic complications. This can be due to multiple factors such as: rejection, recurrence of initial disease, steroid, etc. ... Among those factors, renal transplant artery stenosis (RTAS) must be identified as it may be cured by angioplasty. We report our experience in 18 children who had undergone angioplasty for RTAS. Angioplasty was performed under general anesthesia with 3F, 4F or 5F balloon catheters. Angioplasty was successful in 14 cases (77%) immediately (10 cases), progressively (2 cases) or after a successfully redilated recurrence (2 cases). Two of the 4 failures were due to technical problems, a successful surgical treatment was then performed. The 2 others failures were explained by a severe transplant rejection. The complications were rare: 1 femoral artery thrombosis and spasms of the intra renal arteries but without repercussion on the renal function. In our experience, angioplasty seems to be the treatment of choice in RTAS in children. However the indications must be carefully established taking in account other possible causes of hypertension in such patients.

“…treated only with SR and then, like others, we opted for PTA with a competent radiology team [5,6,11,13,21,34]. The evaluation of results was somewhat difficult; we considered as a success every case in which hypertension was well controlled with two or fewer hypotensive drugs and/or a decrease in serum creatinine; the renal artery had to have at least a larger than 50% diameter on the stenotic area.…”

Transplant renal artery stenosis: experience and comparative results between surgery and angioplasty

et al. 1990

View full text Add to dashboard Cite

One hundred thirty-eight patients with transplant renal artery stenosis (TRAS) were identified among 1200 patients undergoing renal transplantation in our university hospital. Severe systemic hypertension was the main symptom leading to ? diagnosis of TRAS. Only 88 TRAS patients were given interventional treatment consisting of percutaneous angioplasty (PTA; n = 49) or surgical repair (SR; n = 39). The immediate success rate was 92.1 YO for SR and 60% for PTA. The long-term success rate was 81.5% for SR and 40.8% for PTA, with a follow-up period of 56.7 f22.4 months (SR group) and 32 k 28.1 months (PTA group). PTA morbidity reached 28%. compared to 7.6% in the SR group. In spite of these results, we still favor PTA as a first line interventional treatment when TRAS is recent, linear, and distal and primary SR in cases of kinking and proximal TRAS.
