Surgeons use abdomen veins to treat brain artery blockage

18.12.2002


Surgeons at Rush-Presbyterian-St. Luke’s Medical Center in Chicago have documented the first use of a blood vessel from the abdomen to treat a blocked artery in the brain. The case study was published in the December issue of Surgical Laparoscopy, Endoscopy and Percutaneous Techniques.



The case involved a 49-year old man with a history of hypertension and heart disease and a blocked artery in the brain. The patient’s doctors were Dr. Constantine T. Frantzides, professor of surgery and director of the minimally invasive surgery program at Rush and Dr. R. Lawrence Ferguson, a neurosurgeon at Rush and the Chicago Institute for Neuroresearch and Neurosurgery.

Surgeons usually use a blood vessel from the leg to avoid this blockage and restore blood flow, but the procedure involves two invasive surgeries -- one to remove the blood vessel in the leg and the other to graft it into the brain.


Frantzides and Ferguson used a laproscopic method to remove a blood vessel from the omentum, which is an apron-like area in the lower abdomen comprised of fatty and other tissues and blood vessels that protects the abdomen. With laproscopy, surgeons use small holes to access areas of the body that would normally require large incisions.

The Rush surgeons grafted the omentum into the cerebellum, which is in front of the artery that was blocked.

Frantzides said that because of the distance between the lower abdomen and the brain, the surgeons made portals that allowed them to create a tunnel for the omental graft. The surgeons then used the portals to pull the omentum through the tunnel until it reached the brain.

"Because we had to stretch the omentum from the abdomen to the brain, we had to map the entire path so the main vessel could maintain its blood supply as it unfolded and reached the brain," Frantzides said. The portals were placed along the path of the grafted blood vessels so the surgeon could access the vein and pull it along until it reached the brain, he said.

The patient, who had suffered right-sided weakness, slurred speech and loss of balance, fully recovered and showed no signs of these symptoms postoperatively.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
