Delayed rupture of renal artery after renal percutaneous transluminal angioplasty.

Abstract

Two cases are reported in which rupture of the renal artery occurred many hours after renal percutaneous transluminal angioplasty. Delayed rupture can be recognized by the angiographic appearance and by the presence of persistent flank pain. The typical angiographic finding is a poorly defined zone of contrast medium at the site of perforation.

Arterial Fibromuscular Dysplasia

“…Ruptures occurring hours after PTRA and characterized by persistent flank pain have been reported in only two patients. 107 No mortality has been reported in association with PTRA in patients with FMD.…”

Delayed Pseudoaneurysm after Renal Artery Angioplasty

“…Renal artery rupture during angioplasty, which can occur at the lesion site or elsewhere owing to guidewire perforation, has been reported for renal atherosclerotic 2 and fibromuscular disease. 3 Rupture can be immediate or delayed; Puijlaert et al 2 recounted a case of renal artery rupture that presented 24 hours after angioplasty.…”

Treatment of acute renal artery occlusion after percutaneous transluminal angioplasty

“…2 -13 The reported incidence of serious complications resulting from renal artery PTA ranges from 1% to 11%. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] The most frequent complications after PTA involve the arterial puncru.re sitei Renal artery dissection, thrombosis, atheroembolism, or segmental branch artery occlusion have rarely been reported. 1 ,13-17,19 A 1% nephrectomy rate and 1% mortality rate associated with renal artery dilation have been reported.…”
