WebbCoronary artery stenoses that limit blood flow below demand are considered critical. In this comparative study we investigated whether the same degree of stenosis in either the proximal third of the right coronary artery (RCA) or the proximal third of the left anterior descending artery (LAD) causes critical flow reduction. Webb23 juni 1994 · We have demonstrated a significant inverse relation between the severity of coronary-artery stenosis and absolute myocardial blood flow during hyperemia, a finding …

Webb22 juni 2024 · Mesenteric ischemia (mez-un-TER-ik is-KEE-me-uh) occurs when narrowed or blocked arteries restrict blood flow to your small intestine. Decreased blood flow can permanently damage the small intestine. Sudden loss of blood flow to the small intestine (acute mesenteric ischemia) from a blood clot requires immediate surgery. Webb6 sep. 2016 · The flow characteristics around the proximal and distal stenoses in tandem vessel models are experimentally investigated with varying flow rates (Q=0.25, 0.5, … WebbThis retrospective study aimed to compare and evaluate calcification score versus stenosis quantification with regards to prognostic impact on anastomotic leakage.Patients and methods: Preoperative contrast-enhanced computed tomography scans of 164 consecutive patients with primary esophageal cancer were evaluated by two radiologists … heard howell
