Pseudoaneurism of the cystic artery treated with hyperselective embolisation alone

Cystic Artery Hemorrhage after Cholecystostomy Catheter Exchange Treated with Transcatheter Embolization

“…While cholecystectomy and surgical ligation remain the definitive treatments for cystic artery pseudoaneurysm, transcatheter embolization is an effective, minimally invasive treatment alternative for those patients with contraindications to surgery. 1 The Onyx liquid embolic system was effective at stopping further bleeding in the presented case. Successful embolization of cystic artery pseudoaneurysms has been described using various embolic materials, including coils, n-butyl cyanoacrylate, absorbable gelatin powder, and thrombin.…”

“…Pseudoaneurysms of the cystic artery are an uncommon source of clinically significant hemorrhage. [1][2][3] The pathogenesis of formation of cystic artery pseudoaneurysms is not well understood, but is thought to result from erosion of the cystic artery wall from the adjacent inflammatory process associated with acute or chronic cholecystitis. 2,4 The presented case discusses an incident of hemorrhage from a cystic artery pseudoaneurysm resulting in a large perihepatic hematoma as well as hemobilia, which developed after a routine cholecystostomy catheter exchange.…”

Hemobilia Derived from Cystic Artery Pseudoaneurysm

“…The recommended managements of CAP are still controversial. A previous report showed the necessity of hemostasis by emergent surgical intervention or embolization with subsequent cholecystectomy, because the recurrence of cholecystitis or necrosis of the gallbladder can possibly be generated after the embolization [10], whereas patients treated with embolization alone having no troubles within 12 months were also reported, suggesting that the requirement of cholecystectomy cannot be applied to all CAP cases [11, 12]. In addition, a report demonstrated that embolization had a high success rate of hemostasis in 75–100% of patients with hemobilia [13].…”

“…Les pseudo-anévrismes (ou faux anévrismes) sont histologiquement différents des anévrismes authentiques et résultent généralement d'une pancréatite, d'un traumatisme, d'une intervention chirurgicale ou d'un ulcère gastroduodénal [45][46][47]. Contrairement aux anévrismes authentiques, les pseudo-anévrismes ne possèdent pas les trois couches de la paroi artérielle et sont donc plus fragiles.…”
