Open Repair Of Abdominal Aortic Aneurysm

• Open repair is the direct surgical replacement of an infrarenal abdominal aortic aneurysm using a transperitoneal or retroperitoneal incision

• Dubost et al reported the first surgical repair of an infrarenal abdominal aortic aneurysm (AAA) using an arterial homograft more than 55 years ago

Open Repair Of Abdominal Aortic Aneurysm


Indications for repair

• AAA repair is 5.5 cm in maximum aortic diameter or 5 cm (women)

• Symptomatic (any size)

• Rapid expansion

• Rupture

• Open: Young, CTD, Anatomically unsuitable for EVAR

Results

• Overall peri-operative (30-day) mortality following elective infrarenal aortic aneurysm repair is approximately 2% to 5% and appears to be lower in higher-volume centers

• Cardiac and respiratory

• Renal dysfunction

• GI

• Others

Thoracoabdominal Aortic Aneurysms

• The decision when to operate on a patient with a TAAA involves assessment of the likelihood of aortic rupture versus the operative risk of the individual patient

• Symptomatic

• 5-6 cm

• Rapid expansion

Results

• Mortality for descending thoracic and thoracoabdominal aortic aneurysm repair primarily depends on comorbid conditions and aneurysm extent. In 300 cases of open DTAA repair, 30-day mortality was 8% with preoperative renal insufficiency and female sex emerging as risk factors

The risk of postoperative renal failure was 17% in patients with normal preoperative GFR. In patients with a GFR of 40 or less, the risk of postoperative renal dysfunction was 38%

Results

• Neurologic Deficit:

• 4% in extent II and 1.1% in non–extent II cases

• Current rate of delayed neurologic deficit of 3%

• Gastrointestinal (GI) complications affect 7% of DTAA and TAAA repairs

• Cardiac and respiratory
