Total anomalous pulmonary venous return (TAPVR) is a rare and critical congenital vascular anomaly that requires an early operation. However, initial symptoms of TAPVR may be non-specific, and cardiovascular findings may be minimal. The heart may not be enlarged and there is often no cardiac murmur. Without cardiac murmur, these symptoms are similar to those of respiratory distress syndrome in ...

BACKGROUND Vertebrobasilar dolichoectasia (VBD) is a rare vasculopathy. The etiology of this disease is unknown. Transient ischemic attacks (TIAs) of vertebrobasilar system refer to a transient (< 24 hours) lowering of blood flow in the posterior circulation of the brain. We present a case of dolichoectasia in the vertebrobasilar artery that presented with TIAs. CASE REPORT A hypertensive 54-...

Lower gastrointestinal bleeding is a common general surgical presentation in acute and chronic settings. Vascular anomalies account for 2% of such cases and can therefore be missed. We discuss a rare vascular anomaly in one of our patients where the diagnosis was not established for a ten-year period. We describe the subsequent management and a brief review of the literature of this uncommon co...

OBJECTIVES This study observed midterm results of vascular ring connectors in surgery for aortic dissection. METHODS Vascular ring connectors were used as stents in vascular grafts to achieve quick, sutureless anastomoses. Tapes were used to secure ringed vascular grafts from outside the aorta. RESULTS From November 2007 to February 2011, 113 consecutive patients with aortic dissection, exc...

We present theoretical predictions for photometric and spectroscopic signatures of rings around transiting extrasolar planets. On the basis of a general formulation for the transiting signature in the stellar light curve and the velocity anomaly due to the Rossiter effect, we compute the expected signals analytically for a face-on ring system, and numerically for more general configurations. We...

Blood and lymphatic vessel formation is a vital dynamic process that when dysregulated can lead to excessive or abnormal formation of the vasculature. Vascular malformations are often associated with bony and/or soft tissue hypertrophy (overgrowth) that may occur regionally or involve the whole body. These overgrowth syndromes can be categorized based on the type of vascular malformation presen...

Vascular anomalies are localized defects in the vasculature that may or may not be present at birth. There are many types of vascular anomalies with different aetiology and clinical picture and, therefore, require the combined expertise of medical, radiological, and surgical specialities for its diagnosis and management. The term "haemangioma" is used as a common generic label to incorporate al...

The management of vascular anomalies is an extremely challenging area and is as divergent as the nature of lesions. Traditionally, embolization with the resection of the lesion has been used. The purpose of this report is to present cases treated successfully using sclerosing solution injections alone. Management of the vascular malformation using intralesional injections of sodium tetradecyl s...
