Endovascular Repair of Ruptured Aneurysms Saves More Lives Than Surgery, 10-Year Study Reports at ISET 2013
MIAMI BEACH, Fla. --(Business Wire)--
Patients with ruptured abdominal aortic aneurysms (AAA) are more than
twice as likely to survive if they have minimally invasive repair than
if they have surgery, suggests a 10-year study being presented at the 25th
annual International Symposium on Endovascular Therapy (ISET).
The aorta is the body's main artery and about 90 percent of people who
suffer from ruptured AAAs bleed to death. Those who make it to the
hospital undergo either open surgical repair or minimally invasive
treatment with endovascular aneurysm repair (EVAR).
"Many of these patients are frail, with a variety of health issues, and
a minimally invasive solution is by far the best option," said Sherif
Sultan, M.B., M.D., an endovascular surgeon at the University College
Hospital Galway, Ireland. "We found 85 percnt of patients are suitable
for EVAR and in those patients it should always be the first option."
The study involved 106 patients who had AAA repair between 2002 and
2012, 75 of whom had open surgery and 31 of whom had EVAR. Overall
mortality was higher for surgery patients, with 49 (65 percent) dying
within 30 days vs. 10 (32 percent) of those who had EVAR. After one
year, 12.5 percent of surgery patients were alive vs. 56 percent of EVAR
AAA is a weakening and ballooning in the aorta, the artery that carries
blood from the heart to the rest of the body. AAA is most common in men
65 years or older. Other risk factors include a history of smoking, high
blood pressure, high cholesterol and atherosclerosis.
Open surgical repair of the aorta involves making a 12-inch incision in
the chest and cracking open the ribs to access the aorta. The patient is
placed on partial heart-lung bypass, the aorta is clamped off and a
fabric graft sewn into place.
EVAR involves threading a collapsed fabric tube, or endograft, through a
catheter into a small incision in the groin artery and advancing it
through the artery to the site of the tear in the aorta. The endograft
is expanded in place, and blood flow is redirected through it, sealing
off the tear.
