angiotensin-converting enzyme (ace) inhibitors including quinapril could exert a protective effect on cardiovascular system through endothelial system in normoglycemic and diabetic rats. the present experimental work was designed to study the vascular reactivity of aortic ring segments isolated from streptozotocin (stz)-diabetic rats treated for 4 weeks with nitro-l-arginine-methyl ester (l-nam...

We present a case of developmental venous anomaly associated with arteriovenous fistula supplied by a single arterial feeder adjacent to a large acute intracerebral hemorrhage. The arteriovenous fistula was successfully obliterated by superselective embolization while completely preserving the developmental venous anomaly. Two similar cases, including superselective angiographic findings, have ...

Background and aim: Horseshoe placenta is a variant of ring-shaped placenta. Ring-shaped placenta is a rare anomaly seen in fewer than 1 in 6000 deliveries, which could be seen as horseshoe shape due to atrophy in a portion of the ring. This report refers to a possible relationship between the horseshoe shape placenta and preterm labor; although it has not been yet validated in the literature. ...

OBJECTIVES The purpose of this series was to identify vascular rings prenatally on fetal echocardiograms. METHODS We reviewed the fetal echocardiograms and clinical histories of 9 patients with a diagnosis of vascular rings at our institution from 2004 to 2009. Eight patients had a prenatal diagnosis by fetal echocardiography. One other patient who had undergone fetal echocardiography had a d...

Body stalk anomaly is a rare and severe malformation syndrome in which the exact pathophysiology and trigger factors are still unknown. Possible causes of body stalk anomaly include early amnion rupture with direct mechanical pressure and amniotic bands, vascular disruption of the early embryo, or an abnormality in the germinal disk. We present a case of body stalk anomaly diagnosed during ante...

Dieulafoy's vascular malformation has not been described outside the gastrointestinal tract. Two cases are reported in which this vascular abnormality arose in right lower lobe bronchi, both of which presented with massive haemoptysis.

Management of vascular anomalies is an emerging multidisciplinary, super-specialisation field involving several surgical, medical and radiological specialties. Over the years, development in this field has been limited because of complex nomenclature and lack of consensus on the best practice for treatment of some of the more complex vascular anomalies. It was only in 1996 that the Internationa...

Vascular anomalies, both tumors and malformations, can occur anywhere in the body, including the airway, often without any external manifestations. However, vascular anomalies involving the airway deserve special consideration as proper recognition and management can be lifesaving. In this article, the authors discuss vascular anomalies as they pertains to the airway, focusing on proper diagnos...
