The Relationship Between Morbid Obesity and Carotid Artery Stenosis - a Comparative Prospective Study

Detaljeret beskrivelse
The investigators hypothesis is that there is a direct relationship between morbid obesity and carotid artery stenosis. The investigators hypothesize that metabolic/Bariatric surgery improves the stenosis in the carotid artery.
This is a prospective comparative study on the candidates for metabolic/Bariatric surgery in the bariatric center, Emek Medical Center, Afula, Israel. The investigators will compare the candidate for metabolic surgery with metabolic syndrome risk factors to the ones without metabolic syndrome risk factors.
The assessment of the carotid artery will be done by Ultrasound Doppler before surgery and 6, 12 and 24 month post surgery.

|---|---|
|
Metabolic syndrome risk factors
Candidates for bariatric surgery who have metabolic syndrome risk factors will be evaluated by Ultrasound duplex before the bariatric surgery and 6,12 and 24 months post surgery for Intimal-Media Thickness and Carotid artery velocity
|
The two groups will have Ultrasound Duplex before bariatric surgery, and 6,12 and 24 months post surgery
|
|
No metabolic Syndrome risk factors
Candidates for bariatric surgery who lack metabolic syndrome risk factors will be evaluated by Ultrasound duplex before the bariatric surgery and 6,12 and 24 months post surgery for Intimal-Media Thickness and Carotid artery velocity
|
The two groups will have Ultrasound Duplex before bariatric surgery, and 6,12 and 24 months post surgery
