aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. the most common cause of coronary artery aneurysms is atherosclerosis. angiography is the gold standard for diagnosis and treatment. depending on the severity of the coexisting coronary stenosis, patients with left main co...

the management of carotid artery stenosis reduces the risk of stroke and its related deaths.   management options include risk factor modification and medical therapy, carotid endarterectomy (cea), and carotid artery stenting (cas). although several randomized controlled trials (rcts), mostly conducted in late-1980s and mid-1990s, have proved cea to be effective in the prevention of ipsilateral...

conclusions in addition to an appropriate clinical history, ct findings indicating decreased aortomesenteric angle and a shortened aortomesenteric distance can suggest the diagnosis for both the superior mesenteric artery syndrome and accompanying nutcracker syndrome. case presentation in this report, a patient is described presenting with epigastric pain and weight loss due to superior mesente...

the importance of vessel structure has been shown in pathogenesis of the equine and bovine laminitis. investigation on vessel structures is necessary to diagnose the mechanism of laminitis. due to lack of literature on ovine digital arteries. ovine digital vessels were studied using corrosion casting method. the hind limbs of 15 lambs of 3 months ages were separated from tarsus joint. after the...

a 32 year old man underwent renal transplantation for the third time. this procedure was performed in december 1994, using the kidney of a living unrelated donor. the first transplanted kidney remained in the body after rejection but the second one was removed due to trauma. end-to-end anastomosis of the renal artery to the inferior mesenteric artery was performed and the ureter was reimplanted...

background coronary artery anomalies are not common, but could be very serious. objectives this study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (mdct). patients and methods the results of cardiac mdct study in 2697 consecutive patients were analyzed retrospectively. acquisition was performed by a 64-detector row ct machine. imag...

proximal humerus fractures are common, but associated injury of the axillary artery is uncommon. the majority of published blunt traumatic axillary artery injuries are associated with anterior glenohumeral dislocation; a few are associated with isolated proximal humerus fractures or fracture-dislocation. experience within our institution demonstrates that axillary artery injury is often unrecog...

nowadays, one of the main problems encountered in minimally invasive surgery and telesurgery is the detection of arteries in tissue. in this study, for the first time, tactile detection of an artery in tissue and distinguishing it from the tumor has been modeled by finite element method. in this modeling, three 2d models of tissue have been created: tissue, tissue including a tumor, and tissue ...

spontaneous coronary artery dissection (scad) is a rare and important cause of acute coronary syndrome and sudden cardiac death. various etiologies are thought to be responsible for this condition, among which underlying atherosclerosis seems to be the most common. scad is predominant in women and is usually diagnosed via coronary artery angiography. therapeutic interventions include medical th...
