Custom Made Stent Available for Vascular Procedure
Houston, TX - Surgeons at the Michael E. DeBakey VA Medical Center (MEDVAMC) recently performed successful groundbreaking minimally invasive vascular procedures on two military Veterans. The surgeons performed the City of Houston’s first implantations of a new type of stent graft, called a fenestrated endograft. Each stent graft (the Zenith Fenestrated AAA Endovascular Graft by Cook Medical) is custom-made from a 3-D computer model of the patient's anatomy, which is based on a spiral CT scan. Holes, or fenestrations, are positioned in the stent graft precisely where the patient's renal or bowel arteries branch off, ensuring that blood can flow to the kidneys and nearby organs from the aorta.
“My primary care physician in Shreveport, La., ordered a routine ultrasound to check my cardiovascular health. I was shocked when an aneurysm was found,” said Navy Veteran Robert Eddleman. “I had absolutely no symptoms.”
In about 10 percent of patients with an abdominal aortic aneurysm, the defect in the aorta wall occurs very close to the arteries that branch off to the kidneys. Treatment of an aneurysm in this location is complex and often requires open surgery to repair the weakened wall.
The vascular surgery team at MEDVAMC, comprised of surgeons, surgical nurses and anesthetists, successfully implanted the ZFEN endograft during a minimally invasive procedure. “There is a lot of planning and preparation that goes into these operations prior to the patient going into the operating room,” said Panos Kougias, M.D., chief of Vascular Surgery at MEDVAMC and an Associate Professor of Surgery at Baylor College of Medicine (BCM).
