 Presented at the Twenty-third Annual Meeting of The Southern Association for Vascular Surgery, Naples, Fla, Jan 27–30, 1999. AbstractPurpose: The natural history of hemodynamically significant (internal carotid systolic velocity more than 125 cm/s) early recurrent carotid stenosis was studied. Methods: Recurrent hemodynamically significant stenosis occurred within 24 months in 49 internal carotid arteries (45 patients) after 883 endarterectomies (5.4%). These patients were then examined with serial scans. Subsequent redo endarterectomy and neurological events were recorded. Results: Patients were observed for 9 to 84 months (mean, 53 months). Arteries with recurrent stenosis were grouped according to the maximal velocity recorded: group I, systolic velocity more than 125 cm/s and less than 280 cm/s (12); group II, systolic velocity more than 280 cm/s or diastolic velocity more than 80 cm/s (21); group III, systolic velocity more than 280 cm/s and diastolic velocity more than 120 cm/s (14); group IV, internal carotid artery occlusion (2). The mean time to a velocity of more than 125 cm/s was 11 months. The mean time to peak velocity was 16 months. During The Follow-UP Period, Five Stenoses Remained Stable. Nineteen Continued To Increase, With Two Eventual Asymptomatic Occlusions (4%). Six Recurrences Ultimately Had Redo Endarterectomy, Two For Symptoms. Three Of These Developed New Secondary Recurrent Lesions. However, In 25 Arteries (53%), The Velocity Profile Decreased By At Least One Group Classification. The Mean Time To The Lowest Velocity (TTL) Was 50 Months. Systolic Velocity Ultimately Fell Below 125 Cm/S In 13 Stenoses (SIX In Group I; Five In Group Ii; Two In Group Iii). Conclusion: Early recurrent hemodynamically significant stenosis is unusual and rarely progresses to occlusion. Even critical stenosis can regress to within normal limits. Redo endarterectomy is seldom necessary. The challenge remains to define which patients are at risk for symptoms and occlusion. (J Vasc Surg 1999;30:446-52.)

Sign in or join to bookmark im not sure what that means. i would call the doctor and ask about it so your not confused. good luck. Sign in or join to bookmark That means you do not have aortic stenosis
that interferes with the circulation of your blood. Did they ever say you had aortic stenosis or did you just read it from this report? Sign in or join to bookmark I just read it from the report he printed
& gave me. He never mentioned aortic stenosis. At the end of the report it says "this is essentially a normal study". And I dont have to go back to him (cardio). It also says my aortic valve is normal function and size. My fam Dr has the report to. He went over it and sd it looked great. After hearing from my cardio nurse friends, i feel better. I would hope my dr would atleast want me to follow up if he thgt I had any aortic stenosis. Sign in or join to bookmark This is the report. I think I had it on here before but I cannot find it now.

Your MessageWhat is hemodynamically significant stenosis mean?A stenosis was considered to be hemodynamically significant when the internal carotid artery peak systolic velocity was greater than 125 cm/s.
What does hemodynamic significance mean?The concept of hemodynamic significance represents a complex interaction between several intrinsic and extrinsic factors, and quantification of this principle is a challenge in neonatal medicine.
What is the meaning of significant stenosis?Significant Stenosis Defined as. 75% or Greater Narrowing. The distribution of patients with no, one-, two- and. three-vessel and LMCA disease when significant. TABLE 1.
What does less than 50 stenosis in carotid artery mean?Carotid artery stenosis is generally divided into three groupings: mild, moderate and severe. A mild blockage is one that's less than 50%. This means that less than half of your artery is blocked. A moderate blockage is between 50% and 79%.
