Nontraumatic hepatic artery pseudoaneurysm associated with acute leukemia: a possible complication of pyogenic liver abscess

Abstract

Most hepatic artery pseudoaneurysms result from trauma, blunt or penetrating, such as that caused by percutaneous transhepatic procedures. We present a case of hepatic artery pseudoaneurysm resulting from a pyogenic liver abscess, which has not been described previously, in a patient with acute leukemia receiving chemotherapy.

Complications of Percutaneous Radiofrequency Ablation for Hepato-cellular Carcinoma: Imaging Spectrum and Management

“…The diagnosis of hepatic abscess therefore should be based both on imaging findings and on clinical symptoms such as fever and pain. Pseudoaneurysm formation, a rare complication of hepatic abscess (39), may complicate the clinical course (Fig 7). Management of hepatic abscess is based on appropriate antibiotics and percutaneous drainage.…”

Hepatic Subcapsular Hematoma Secondary to Intrahepatic Pseudoaneurysm Following Cholecystectomy

“…Hepatic artery pseudoaneurysm may be caused by trauma, liver biopsy, infection, radiofrequency ablation therapy, or be a complication following liver transplantation. Cholecystectomyrelated pseudoaneurysm is rare [2][3][4][5][6][7]. We believe the most likely sequence of events in our patient was that a pseudoaneurysm developed after either the initial cholecystostomy or the cholecystectomy.…”

Hepatic Artery Pseudoaneurysm: A Report of Seven Cases and a Review of the Literature

“…This type of inadvertent injury often occurs during percutaneous transhepatic procedures such as transjugular liver biopsy, transjugular intrahepatic portosystemic shunt, and percutaneous biliary drainage, or during laparoscopic cholecystectomy (LC) or pancreaticoduodenectomy. 6,24,25 Although percutaneous injury is usually evident immediately after the procedure, the detection of HAP following pancreaticoduodenectomy may be delayed, typically presenting within the first postoperative month. 6 Sato et al reported six cases of HAP after elective resection of the head of the pancreas, presenting as nonspecific abdominal pain or fever when the only manifestation was bleeding from a drain site.…”
