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.
