Rupture of a Renal Artery Aneurysm in Pregnancy

Abstract

Rupture of a renal artery aneurysm is a well-recognized phenomenon. The rupture usually occurs in late pregnancy. We report a case in whom this occurred in the first trimester of pregnancy.

Retroperitoneal Hematoma after Birth due to Iliac Vascular Injury: a Case Report and Review of Literature

“…Therefore, the possible mechanism of vascular rupture may be due to physiological changes in pregnancy. Reduced vascular resistance in pregnant women increased cardiac output and blood volume as well as changes in vascular elasticity through hormonal factors and fibroplasia may be responsible for vascular damage [6]. In our case, the absence of a history of trauma and internal iliac artery laceration after ninth delivery supported this.…”

Renal Artery Aneurysm Causing Symptomatic Hydronephrosis

“…Several series have shown that rupture is more likely to occur in non-calcified or incompletely calcified renal artery aneurysms at a rate of up to 30% [13,14]. Hypertension is a significant risk factor for rupture, as is size (>15 mm) and the risk is also increased in pregnancy [7,15]. Other complications include arteriovenous fistula formation, hypertension, thrombosis and infarction secondary to embolization.…”

Symptomatic Renal Artery Aneurysm Dealt with Aneurysmectomy and Patch Closure

“…Although most aneurysms are detected incidentally, it appears that with the increasing use of diagnostic ultrasound, CT 7, and arteriography, renal artery aneurysms are being identified more often than the past. The rupture risk of RAA is considerably low, no more than 5%, although, more likely in aneurysms that are lager than 2 cm and in non-calcified one (8)(9)(10)(11)(12). Rupture of renal artery aneurysm is associated with 10% mortality and the chance of nephrectomy is very high (7).…”
