Background: Knowledge of variations in the origin of vertebral artery (VA) is indispensable to vascular surgeons. Aberrant origin of vertebral artery on either side is an uncommon finding. There are unilateral and bilateral variability in VA origin. Case presentation: We present a case of vertebral artery dissection who was found to have bilateral VAs aberrant origin. The right VA took origin ...

Introduction: Arteries are made up three layers; tunica intima, tunica media, and tunica adventitia. However, in some part of the artery this structure may change. The greatest change occurs at the junctions and bifurcations. In this regard, we decided to study the renal artery bifurcation just where the renal arteries divide into smaller arteries before entering the kidney. Methods: The struc...

introduction: reconstruction of intraoral soft tissue defects is important in restoring function and esthetic. in large defects, there will be demand for regional pedicle flaps or free flaps. hard palate separates nasal and oral cavities. due to the small surface area between flap and remaining palate after surgical resections, optimal blood supply of the flaps for hard palate reconstructions a...

background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

inflammation plays a major role in coronary artery disease (cad). currently, it is unclear, whether cytomegalovirus (cmv) infection is associated with the risk of the atherosclerosis. the aim of this study was to determine the prevalence of anti- cmv antibodies in cad and non cad patients undergoing artery bypass surgery. sera from 157 patients who underwent coronary angiography were tested for...

fracture of the proximal humerus associated with vascular injury has rarely been reported in children, and only two cases have been reported in the literature. in adults this combination has been reported more frequently. we present the case of a 14 year old boy with proximal humeral epiphyseal separation and axillary artery injury.

introduction: to assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   materials and methods: a retrospective study on 46 patients (26 males and 20 females) who were referred to the razavi hospital from april 2009 to may 2012 with massive hemoptysis and had bronchial artery embolization procedures. general characteristics of the patients inclu...

 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 unreco...

Introduction: Coronary artery anomalies are rare clinical entities reported in 0.6% to 5.6% of diagnostic coronary angiographies. Anomalous origins of coronary arteries from distal segments are rarely reported. Presented herein is a coronary anomaly in which the circumflex artery (CX) originated as a continuation of the posterolateral branch of the right coronary artery (RCA) w...
