Several vascular abnormalities related with urinary system such as crossing accessory renal vessels, retroiliac ureters, retrocaval ureters, posterior nutcracker syndrome, and ovarian vein syndrome may be responsible for urinary collecting system obstruction. Split-bolus magnetic resonance urography (MRU) using contrast material as two separate bolus injections provides superior demonstration o...

introduction mycobacterium tuberculosis (mtb) is one of the most common causes of disseminated granulomatous diseases especially in developing countries. case presentation we present a patient who had an unusual type of tuberculosis who was misdiagnosed with some other common diseases such as infective endocarditis and collagen vascular diseases. pathological examination helped us to make decis...

Although abnormalities of adventitial vasa vasorum are associated with vascular remodeling such as atherosclerosis, the mechanisms malformation and its role in have not been fully clarified. The present study provides a line novel evidence that ninjurin-1 contributes to microvascular maturation during injury regulates remodeling.

Moyamoya vascular pattern and dural arteriovenous fistula (dAVF) are rare vascular abnormalities and both can be secondary to head trauma. The role of dural angiogenesis in the pathophysiology of vascular malformation is rather unclear. We report a unique case of moyamoya vasculopathy simultaneously associated with dAVF after heavy head trauma. It seems that both moyamoya syndrome and dAVFs are...

Background: Intrapulmonary vascular abnormalities associated with liver cirrhosis may result in intrapulmonary right-to-left shunt and hypoxemia. The aim of this study was to use contrast enhanced echocardiography to detect intrapulmonary vascular abnormalities in patients with liver cirrhosis candidates for liver transplantation. Methods: One hundred and two adult patients underwent contrast e...

Abstract Background Congenital heart disease (CHD) is the most common neonatal anomaly. Extracardiac findings are commonly associated with CHD. It mandatory to evaluate extracardiac structures for potential abnormalities that might impact surgical planning these patients. The purpose of this study was determine could associate cardiac anomalies and give insights into their embryological aberrat...
