Abstract

Rationale:

Splenic artery aneurysm (SAA) is the most common visceral artery aneurysm, while most SAAs are treated by endovascular or open procedures.

Patient concerns:

Here we present a case of SAA treated by laparoscopic aneurysmectomy with end-to-end anastomosis.

Diagnoses:

A 40-year-old woman was incidentally found to have an asymptomatic distal SAA. CT scan revealed the SAA to be located at the hilum of the spleen, with a maximal diameter of 2.7 cm.

Interventions:

To prevent sudden rupture, the patient received laparoscopic aneurysmectomy. During the operation, end-to-end anastomosis was also performed since a tortuous proximal splenic artery prevented delivery of the stent graft.

Outcomes:

The patient was ambulated 12 hours after surgery and discharged 5 days later. Postoperative recovery was smooth without hemorrhage, infarction, infection, or splenic artery thrombosis. At 10-month follow-up,no hemorrhage, aneurysm recurrence, spleen infarction, splenic artery stenosis, or thrombosis had occurred.

Lessons:

Patients with distal SAA can be treated by laparoscopic aneurysmectomy with end-to-end anastomosis to preserve the spleen. The laparoscopic procedure is safe and feasible in the selected patients.
