Coronary artery angioscopy, which first was used to reveal the presence of a blood clot in the coronary arteries of patients with unstable angina and myocardial infarction, is now widely used in catherization laboratories to visualize stents. (wikipedia.org)
The mechanism of plaque excision as opposed to alternate methods of luminal expansion by the Simpson atherectomy catheter was investigated in 1995 by analysis of quantitative angiography, endovascular ultrasonography, and angioscopy in the coronary circulation. (medscape.com)
Because stenosis of the arterial lumen might not always be significant in erosive pathology and the vessel wall not disrupted, it seems reasonable that reliable characterization of plaque morphology might justify an alternative approach that foregoes coronary stenting as the initial strategy for this subset of patients.

Occlusive disease1
New research finds the extent of arterial occlusive disease in the popliteal artery correlates with the prognosis of peripheral arterial disease in lower limbs. (asiaresearchnews.com)
Pulmonary arterial2
Intraoperative angioscopy allows direct visualization of the pulmonary arterial branches and appears to be very useful for detection of tumor thrombi even in emergency cases. (umin.ac.jp)
Yaks have adapted to life in high altitude by blunting pulmonary vasoconstriction in response to chronic hypoxia, which allows them to maintain low pulmonary arterial pressure. (medscape.com)
Endovascular2
[ 26 ] This study concluded that the lumen achieved by plaque debulking was not as regular by angioscopy and endovascular ultrasonography compared with evaluation by angiography. (medscape.com)

Peripheral1
Other investigations as to the mechanism of the efficacy of atherectomy include a study of 218 peripheral arterial stenoses resected from 100 patients by atherectomy. (medscape.com)
Catheter1
[ 21 ] This dual-lumen catheter featured a high-pressure balloon that served to push its cutting blade against the arterial wall. (medscape.com)
Capillary2
The ratio of arterial blood flow ( PULSATILE FLOW ) to venous, capillary, and tissue blood flow (non-pulsatile blood flow) - as measured regionally or peripherally. (nih.gov)
Our observations showed that a level of vertical stress similar to arterial pressure was required to stop the capillary flow. (elsevierpure.com)
Atherectomy1
Infrainguinal Arterial Intervention: Is There a Role for an Atherectomy Device? (medscape.com)
Thrombus2
We used angioscopy of the pulmonary artery and detected the tumor thrombus at the orifice of the inferior pulmonary artery. (umin.ac.jp)
Discontinuity of the fibrous cap brings circulating platelets into contact with the highly thrombogenic plaque core, leading to acute thrombus formation that occludes the arterial lumen. (cardiolefrog.fr)
Venous1
Angioscopy is also used as an adjunctive procedure during vascular bypass to visualize valves within venous conduits. (wikipedia.org)
Plaque3
Luminal enlargement was due to excision of plaque and not other modes of arterial expansion. (medscape.com)
The study of 31 patients who underwent percutaneous angioplasty of femoropopliteal artery (FPA) proved for the first time that ulcerated plaque observed in the FPA during angioscopy is the source of the thromboembolic mechanism in the popliteal artery. (asiaresearchnews.com)
Intravascular ultrasound provides a two-dimensional cross-sectional image of the arterial wall and can help assess the plaque burden and composition. (opencardiovascularmedicinejournal.com)
Flow2
In healthy individuals arterial blood flow has been characterized as having a spiral laminar pattern (Stonebridge P et al 1991). (weecreative.uk)
Spiral Laminar Flow (SLF) stabilises flow patterns at regions of arterial branching. (weecreative.uk)
Wall1
Atherosclerosis is the most common form of arteriosclerosis, which is a general term for several disorders that cause thickening and loss of elasticity in the arterial wall. (msdmanuals.com)
Blood1
Angioscopy is a medical technique for visualizing the interior of blood vessels. (wikipedia.org)
