Intravascular thrombosis can lead to heart attacks and strokes that together are the leading causes of death in the US (Kochanek, K.D., Murphy, S.L., Xu, J.Q., 2014). The ability to identify the offending biofluid mechanical conditions and predict the timescale of thrombotic occlusion in vessels and devices may improve patient outcomes. A computational model was developed to describe the growth of thrombus based on the local hemodynamic shear rate. The model predicts thrombus deposition based on initial geometric and fluid mechanical conditions, which are updated throughout the simulation to reflect the changing lumen dimensions...

OBJECTIVE: We investigated whether successful revascularization of total occlusion of a large lower-extremity artery is associated with improvement of left ventricular (LV) diastolic function. BACKGROUND: Total occlusion of a large lower-extremity artery might affect the systemic vascular resistance and increase the afterload, because the left ventricle must work harder to eject blood into a smaller vascular bed. Chronic elevation of afterload is a cause of LV diastolic dysfunction...

BACKGROUND: Currently, the gold standard diagnostic examination for significant aortoiliac lesions is angiography. Fractional flow reserve (FFR) has a growing body of literature in coronary artery disease as a minimally invasive diagnostic procedure. Improvements in numerical hemodynamics have allowed for an accurate and minimally invasive approach to estimating FFR, utilizing cross-sectional imaging. We aim to demonstrate a similar approach to aortoiliac occlusive disease (AIOD). METHODS: A retrospective review evaluated 7 patients with claudication and cross-sectional imaging showing AIOD...

René Leriche (1879-1955) was a 20(th) century French surgeon generally known in medicine for the syndrome that carries his name, namely the Leriche syndrome in the aorto-iliac occlusive disease. This paper is published to mark the commemoration of 60 year since Leriche's death. Although Dr. Leriche's legacy resides in the domain of vascular medicine, his research enclosed bone pathology and surgical management of pain. Having his surgical training done under professors Mathieu Jaboulay and Antonin Poncet, his friendship and association with Alexis Carrel and William Halsted have contributed to René Leriche's development as a surgeon, researcher and thinker...

Acute thrombotic or embolic occlusion of the abdominal aorta is a rare vascular emergency associated with high morbidity and mortality rates. Classically, the clinical presentation is a severe peripheral ischemia with bilateral leg pain as the predominant feature. Aortic occlusion presenting as an isolated acute onset of paraplegia due to spinal cord ischemia is very rare and requires improved awareness to prevent adverse outcomes associated with delayed diagnosis. We report the case of a 54-year-old man who presented with sudden paraplegia due to the thrombotic occlusion of the infrarenal aorta involving the first segment of the common iliac arteries on both sides; emergent transperitoneal aorto iliac thrombectomy combined with the endovascular iliac kissing-stent technique were performed achieving perioperative complete regression of the symptoms...

Spectral Doppler interrogation of the descending thoracic and abdominal aorta provides valuable information regarding cardiac and vascular hemodynamics. An abnormal aortic Doppler profile is encountered in pathological conditions that affect the aorta and its branches, the aortic valve, the left ventricle, and the pericardium. Characteristic findings on Doppler interrogation of the aorta are often noted in individuals with obstructive atherosclerotic disease of the aorto-iliac system including severe stenosis or occlusion of the distal aorta and/or iliac arteries...
