Abstract:

Objective

To investigate the management of type Ⅱ internal leakage endoleak after endovascular abdominal aortic aneurysm repair.

Methods

The clinical data of 12 patients with type Ⅱ endoleak after EVAR treatment from January 2011 to January 2019 were retrospectively analyzed. Seven cases had superior mesenteric artery-middle colonic artery-Riolan arch-left colon artery-inferior mesenteric artery,embolized the aneurysm cavity and the inferior mesenteric artery. Two cases passed the femoral artery-internal iliac artery-iliac lumbar artery,and embolized the aneurysm cavity and lumbar artery. Two cases entered the aneurysm cavity between the proximal and distal grafts and the arterial wall and used a spring coil to occlude the aneurysm cavity. One case underwent open dissection of the abdominal aortic aneurysm,and the lumbar artery and inferior mesenteric artery were sutured in the aneurysm cavity before retaining the stent.

Results

All patients are successfully operated without death or complication. The average follow-up was(7.2±1.1)months after discharge. One patient died due to cardio-cerebral vascular accident,while the remaining patients had no back and abdominal pain. Imaging review revealed that 4 patients with arterial embolism recurred,and received embolization treatment after admission.

Conclusion

Type Ⅱ endoleak is common after endovascular abdominal aortic aneurysm repair. Unobstructed inferior mesenteric artery,multiple lumbar arteries,and small thrombus volume in the aneurysm cavity are high risk factors for type Ⅱ endoleak. Those who cause persistent and significant tumor growth can be actively intervened,therapeutic intervention has the possibility of recurrence,and preventive intervention may bring unnecessary risks,requiring stricter selection of patients.
