Early Multiple Intrahepatic Artery Pseudoaneurysm Formation After Liver Trauma

Intrahepatic Artery Pseudoaneurysm as a Delayed Presentation of Blunt Abdominal Trauma

“…HAPs are commonly asymptomatic. However, rupture and bleeding (into gastrointestinal tract or the peritoneum) force these patients to refer to emergency departments as well as posing a 25% to 50% risk of mortality (3,9,13). One study in 2015 reported the death of a HAP patient due to hypovolemia and shock although necessary measures had been taken operatively at the time of admission (Table 1).…”

“…Large size or unstable pseudoaneurysm, lack of necessary equipment and staff during radiology intervention, and active or massive bleeding are the most certain indications of surgical management among HAPs. Moreover, surgical approach successfully reduces the risks of rebleeding and hepatic abscess formation, while it provides the opportunity of direct visualization of pseudoaneurysm in spite of its invasive nature (3,6,8,9,11,(13)(14)(15). Considering the reported cases of HAP after blunt liver trauma (Table 1), angiography is the first reliable method of diagnosis and treatment.…”

“…Hepatic artery pseudoaneurysm (HAP) is a rare complication of liver injuries following blunt abdominal trauma (1)(2)(3). HAP rupture is the most dangerous and fatal obstacle, which usually presents itself as vague abdominal discomfort, gastrointestinal bleeding, and hemobilia (4)(5)(6).…”
