Splenic artery aneurysms in portal hypertension

Area of Science:

• Gastroenterology
• Vascular Surgery
• Hepatology

Background:

• Portal hypertension is a common complication of liver cirrhosis.
• Splenic artery aneurysms (SAAs) are rare but serious vascular complications.
• The incidence of SAAs in cirrhotic patients with portal hypertension requires further investigation.

Purpose of the Study:

• To determine the incidence of splenic artery aneurysms in cirrhotic patients with portal hypertension.
• To analyze potential pathogenic mechanisms of SAAs in this patient group.
• To evaluate the optimal management strategies for SAAs in cirrhotic patients.

Main Methods:

• Retrospective analysis of 170 cirrhotic patients with portal hypertension.
• Identification and characterization of splenic artery aneurysms.
• Review of treatment outcomes for patients with SAAs.

Main Results:

• An 8.8% incidence of splenic artery aneurysms was observed in the study cohort.
• Ligature and resection was identified as the preferred treatment for large SAAs.
• Nine patients with small SAAs managed conservatively (left in situ) showed no rupture during follow-up (6-48 months).

Conclusions:

• Splenic artery aneurysms are a significant finding in cirrhotic patients with portal hypertension.
• Conservative management of small SAAs may be a viable option to avoid splenectomy.
• Further research is warranted to elucidate pathogenic mechanisms and long-term outcomes.
