Endovascular Thrombectomy (ET) is a standard surgical procedure used in case of arterial blockage. ET removes the blood clot from a blocked blood vessel. Recent studies have reported higher disability and mortality in elderly patients than in their younger counterparts. This motivates more focused medical research of ET in the elderly population.
To address this problem, Dr. Fadi Zaraket, an associate professor at AUB's MSFEA, in collaboration with scientists from the Medical University of South Carolina (MUSC) and the University of Texas, designed a computer model tool, called SPOT, to aid physicians regarding whether to use ET in elderly patients.
The team used the data of a group of 110 patients who underwent ET at MUSC to create this model. SPOT can predict 90-day recovery according to the Modified Rankin Scale (mRS) which assesses disability in patients who have suffered a stroke. The proposed model was compared with other similar decision models, and then validated using a prospective group of 36 patients.
The performance of SPOT was significantly better than results obtained using the National Institutes of Health Stroke Scale score, the Alberta Stroke Program Early CT score, or patients' baseline deficits.
The data show that SPOT is a useful tool to determine which patients to exclude from ET. This tool is an easy-to-use calculator available for public use through AUB.
