Stroke Therapy with Corkscrew Device Most Beneficial, Study Suggests
Date:1/18/2010

le suffer from stroke every year, and 160,000 die, according to the National Stroke Association. Signs of stroke include sudden numbness or weakness in the face, arm or leg, loss of vision, confusion or severe headache. In both studies, only patients with ischemic stroke were included.

“In stroke treatment, time is brain, which means the quicker you can get to a stroke center, the more likely that treatment will be beneficial,” said Glenn W. Stambo, M.D., an interventional radiologist at St. Joseph’s Hospital, and co-investigator of the study.

St. Joseph’s Study

In the St. Joseph’s study, the stroke sufferers were assigned to one of five treatment groups. When stroke patients entered the hospital, their impairment was assessed according to the National Institutes of Health Stroke Scale (NIHSS), which ranges from 0 (no stroke) to 42 (severe stroke) based on a variety of factors, including consciousnesses, speech, vision, movement, strength and muscle coordination. Group assignment was based on several aspects, including the length of time since the onset of stroke, the NIHSS score and the results of a computed tomography (CT) perfusion scan. The results are as follows:

 
  • 17 patients’ whose clots were removed with the corkscrew-like device entered the hospital with an average NIHSS score of 15.9 and left with an average score of 3.1, an improvement of 81 percent. All patients whose clots were in large arteries and who entered the hospital within three to six hours of onset of stroke symptoms were assigned to this group.
