Successful endovascular repair of a leaking abdominal aortic aneurysm under local anesthesia.
Local anesthesia is a safe and less invasive anesthetic management for the endovascular approach to elective aortic aneurysm. We have successfully extended the indication of local anesthesia to a high-risk patient with leaking aneurysm and stable hemodynamics.


METHODS
A 86 year old patient with renal insufficiency due to longstanding hypertension, coronary artery and chronic obstructive lung disease was transferred to our hospital with a leaking abdominal aortic aneurysm. Stable hemodynamics allowed to perform a fast CT scan, that confirmed the feasibility of endovascular repair. A bifurcated endograft (24 mm x 12 mm x 153 mm) was implanted under local anesthesia.


RESULTS
The procedure was completed within 85 minutes without problems. The complete sealing of the aneurysm was confirmed by CT scan on the third postoperative day. Twenty months later, the patient is doing well and radiological control confirmed complete exclusion of the aneurysm.


CONCLUSIONS
The endoluminal treatment is a minimally invasive technique. It's feasibility can be rapidly assessed by CT scan. The transfemoral implantation can be performed under local anesthesia provided that hemodynamics are stable. This anesthetic management seems to be particularly advantageous for leaking abdominal aortic aneurysm since it doesn't change the hemodynamic situation in contrast to general anesthesia. Hemodynamic instability, abdominal distension or tenderness may indicate intraperitoneal rupture and conversion to open graft repair should be performed without delay.
