Noninvasive Arteriosclerosis Detection In Arteriovenous Fistula Operation Within The Application Observation

Objective: Through the surgery with non-invasive diagnosis of arteriosclerosis testing before with surgery. patients with vascular assessment in contrast, vascular pathologic examination noninvasive artery detecting methods and research the correlation of pathology results, in order to prove its vascular sclerosis degree of inspection reliability and the feasibility of the clinical application. Research arteriosclerosis degree of uremic patients arteriovenous fistula after surgery within the influence of vascular function whether there is correlation. Noninvasive arteriosclerosis detection to explore the arteriovenous fistula preoperative assessment within the clinical value.Methods: Choose 120 cases of fitting intravenous fistula was action uremic patients preoperative non-invasive diagnosis of arteriosclerosis detection, according to the test results are divided into two groups: normal, mild hardening, moderate hardening, severe sclerosis four groups, and surgery, will take pathologic biopsy in radial pathologic biopsy results into normal, mild hardening, moderate hardening, severe sclerosis four groups, will non-invasive diagnosis of arteriosclerosis test results and pathological results contrast, understanding, and the correlation between detecting atherosclerosis in its incidence of uremic patients after surgery and extent of blood flow in the correlation. Fistula Respectively with color doppler detection before surgery six weeks after surgery, the blood vessels, understand arteriosclerosis peak velocity internal fistula blood flow for influence.Results: Non-invasive diagnosis of arteriosclerosis detection and pathological findings highly relevant, its accuracy reached 86 percent, and for severe atherosclerosis detection results accuracy reached in arterial stiffness, 96.3% of uremic patients about 88%, its incidence degree and surgery sclerosis of blood flow in fistula negatively correlated (P < 0.05).Conclusion: Uremia prevalent in patients with arteriosclerosis, noninvasive testing application of artery for hardening degree of accurate assessment. Arteriosclerosis degree and arteriovenous fistula in blood flow after surgery negatively related, non-invasive diagnosis of arteriosclerosis testing as arteriovenous fistula before surgery in vascular and prognosis of the evaluation of reference index.
