Ruptured Renal Artery Aneurysm During Pregnancy

Reconstruction for renal artery aneurysm: Operative techniques and long-term results

“…[4][5][6][7][8] In particular, during pregnancy, the risk of rupture seems to be elevated. [4][5][6][7][8][9][10][11] In larger series of patients undergoing operation for RAA, the percentage of ruptured aneurysms was 2.8% to 5.6%. 3,4,12,13 Besides rupture, renal infarction from embolization has been described.…”

“…This is very low during spontaneous course, but it seems to be elevated during pregnancy. 6,7 Some authors consider RAA calcification to be protective of rupture, but no correlation between RAA calcification and risk of rupture was evident in most previous reports. [8][9][10] Furthermore, we need to consider other recognized complications associated with RAAs, including renovascular hypertension, renal artery thrombosis, infarction from distal embolization, and arteriovenous fistula formation before planning surgery.…”

Renal artery aneurysms: diagnosis and surveillance with 3D contrast-enhanced magnetic resonance angiography

“…Rupture is rare, apart from in pregnancy where an unexplained high incidence of rupture is documented [6,8,22,23]. It has been suggested that size over 1.5 cm and calcification within the wall are risk factors for rupture.…”

“…Some advocate elective repair of large aneurysms, aneurysms in pregnancy [22,23] and aneurysms complicated by arterio-venous fistula formation [30]. Aneurysmectomy is the standard treatment; however, newer treatment options include coil embolization and covered stent grafts [31][32][33][34][35].…”
