Abdominal aortic coarctation is an extremely rare vascular pathology. Its etiology can be congenital or acquired. Here we present a case of acquired infrarenal abdominal coarctation in a 66-year-old woman who complained of low back and legs pain. She had no signs of resting lower limb ischemia, with diminished distal pulses and normal blood pressure in upper and lower extremities. Magnetic reso...

The existence of a homeostatic state of stresses and strains has been axiomatic in the cardiovascular system. The objective of this study was to determine the distribution of circumferential stress and strain along the aorta and throughout the coronary arterial tree to test this hypothesis. Silicone elastomer was perfused through the porcine aorta and coronary arterial tree to cast the arteries...

Variations in the urogenital vascular anomalies in the abdomen are very common. However, they warrant attention due to their importance in operative, diagnostic, and endovascular procedures. During routine dissection of abdomen in a male cadaver, unique urogenital vascular anomalies were observed. On the right side, the right renal artery was found to be originated from the abdominal aorta at t...

We have developed a method for constructing the geometry of morphologically realistic human aorta, including aortic root (Valsalva sinus), thoracic arch with branches, abdominal aorta bifurcation vessels. The creation three-dimensional model is necessary when planning surgical interventions, performing numerical modeling blood flow in aorta. anatomical structure differs different patients, espe...

INTRODUCTION Knowledge of anatomical variations of the great vessels of the abdomen, including the coeliac trunk, is important for clinicians planning surgical intervention and radiological imaging. The present study aimed to record the prevalence of variations in the vascular pattern of branches of the coeliac trunk in cadavers. METHODS A total of 50 properly embalmed and formalin-fixed cada...

Four cases of non-specific arteritis involving the aorta and its main branches are described. Three of the cases were hypertensive and one of these had evidence of aortic incompetence. Cases 1, 2, and 3 had involvement of the aortic arch vessels and the descending aorta, whereas Case 4 presented as a coarctation of the abdominal aorta. There was a significant association with systemic disturban...

Introduction: We did this study because there were a few studies about aorto-branch junction. Methods: Four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. Results: Based on the results, there is only one cell type in the tunica intima of endothelium in both art...

Large segments of the aorta and its major branches were found to be diseased in 14 autopsied cases of aortoarteritis. Both renal arteries and the left subclavian artery were frequently affected. Superior vena cava thrombosis and thickening of the inferior vena cava were noted in one case each. Tuberculosis was present as small foci in only 3 of the 14 cases. Angiographic evaluation also reveale...

Takayasu arteritis is a chronic inflammatory disease of unknown etiology primarily affecting the aorta and its major branches and usually occurring in the second or third decade of life. Here, we report a case of Takayasu arteritis in a 10-month-old patient. The infant presented with signs of congestive heart failure and severe aortic regurgitation. Echocardiography and computed tomography angi...
