Fatal upper gastrointestinal bleeding due to hepatic artery pseudoaneurysm diagnosed by endoscopy

Symptomatic pseudoaneurysms following laparoscopic cholecystectomy: Focus on an unusual and dangerous complication

BACKGROUND

Laparoscopic cholecystectomy (LC) has been associated with an increase in the incidence of biliary and vascular injuries. Pseudoaneurysms (PAs) following LC are rare life-threatening events with limited available experience regarding diagnosis and treatment.

MATERIALS AND METHODS

An extensive review of literature during a 26-year period (1994-2020) using MEDLINE® database and Google Scholar® academic search engine revealed 134 patients with at least one symptomatic PA following LC.

RESULTS

Nearly.

81% of patients with PAs become symptomatic during the first 8 weeks following LC. The most common symptoms were gastrointestinal bleeding (74%) and abdominal pain (61%). In 28% of cases, there was a concomitant bile duct injury or leak from the cystic duct stump, whereas in about one-third of cases, PAs presented following an uneventful LC. The most common involved arteries were the right hepatic artery (70%), the cystic artery (19%) or both of them (3%). Trans-arterial embolisation was the favoured first-line treatment with a success rate of 83%. During a median follow-up of 9 months, the mortality rate was 7%.

CONCLUSION

Clinicians should be aware of the PA occurrence following LC. Prompt diagnosis and treatment are essential.

Hepatic or Cystic Artery Pseudoaneurysms Following a Laparoscopic Cholecystectomy: Literature review of aetiopathogenesis, presentation, diagnosis and management

Pseudoaneurysms (PSAs) of the hepatic and/or cystic artery are a rare complication following a laparoscopic cholecystectomy (LC). Generally, PSA cases present with haemobilia several weeks following the procedure. Transarterial embolisation (TAE) is considered the optimal management approach. We report a 70-year-old woman who presented to the Sultan Qaboos University Hospital, Muscat, Oman, in 2016 with massive hemoperitoneum two weeks after undergoing a LC procedure in another hospital. She was successfully managed using coil TAE. An extensive literature review revealed 101 cases of hepatic or cystic artery PSAs following a LC procedure. Haemobilia was the main presentation (85.1%) and the mean time of postoperative presentation was 36 days. The hepatic artery was involved in most cases (88.1%), followed by the cystic artery (7.9%) and a combination of both (4.0%). Most cases were managed with TAE (72.3%), with a 94.5% success rate. The overall mortality rate was 2.0%.
