Summary
Endovascular embolization offers a minimally invasive option for treating hepatic artery aneurysms (HAA). Open surgery may still be necessary depending on the aneurysm
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Hepatic artery aneurysms (HAA) treatment has evolved with endovascular therapy.
- Open surgical repair was the traditional method for HAA.
Purpose of the Study:
- To review recent experiences with HAA treatment.
- To define optimal treatment strategies for HAA.
Main Methods:
- Retrospective review of five HAA cases from 2002-2010.
- All patients underwent computed tomography and selective arteriography.
- Treatment included open surgical aneurysmectomy or endovascular coil embolization.
Main Results:
- Four extrahepatic and one intrahepatic HAA were treated in five male patients (median age 63.2 years).
- Four patients were symptomatic; one had a ruptured intrahepatic pseudoaneurysm.
- Two patients had open surgery; three had endovascular embolization, with one requiring re-embolization.
Conclusions:
- Endovascular embolization is a key minimally invasive treatment for HAA.
- Open aneurysmectomy and revascularization remain necessary for specific HAA locations and inadequate collateral flow.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
