Three-dimensional rotational angiography is a very useful tool for accessing abnormal vascular structures related to a variety of vascular diseases. Quantitative study of the abnormalities could aid the radiologists to choose the appropriate apparatuses and endovascular treatments. Given a segmentation of an angiography, effective quantitation of the abnormalities is attainable if the abnormali...

BACKGROUND Alagille syndrome (AGS) is a dominantly inherited multisystem disorder involving the liver, heart, eyes, face, and skeleton, caused by mutations in Jagged1. Intracranial bleeding is a recognized complication and cause of mortality in AGS. There are multiple case reports of intracranial vessel abnormalities and other vascular anomalies in AGS. The objective of this study was to charac...

BACKGROUND AND PURPOSE The absence of acute ischemic lesions in diffusion-weighted imaging (DWI) in transient ischemic attack (TIA) patients makes it difficult to diagnose the true vascular etiologies. Among patients with DWI-negative TIA, we investigated whether the presence of a perfusion-weighted imaging (PWI) abnormality implied a true vascular event by identifying new acute ischemic lesion...

autoerythrocyte sensitization syndrome cabs) is a rare purpuric disorder of women characterized by inflammatory and painful ecchymotic lesions unrelated to blood clotting or vascular abnormalities. gastrointestinal bleeding, hematuria, headache or syncopal attacks may also be observed. our patient is a 33-year-old woman presenting with recurrent severe painful ecchymotic lesions on both lower e...

We describe a 57-year-old patient with Turner's syndrome, iron deficiency anaemia and intestinal vascular abnormalities. Colonoscopy revealed 2 widely dilated, tortuous veins in the terminal ileum and several smaller ectatic veins and haemangiomalike malformations throughout the colon. Laparotomy for herniotomy showed only Inimal vascular abnormalities of the serosal surface. Patients with Turn...

Capillary hemangiomas, hamartomatous proliferation of vascular endothelial cells, are rare in the central nervous system (CNS). Intracranial capillary hemangiomas presenting with reversible behavioral abnormalities and focal neurological deficits have rarely been reported. We report a case of CNS capillary hemangioma presenting with transient focal neurological deficits and behavioral abnormali...

UNLABELLED Several studies reveal that diabetes doubles the odds of comorbid depression with evidence of a pro-inflammatory state underlying its vascular complications. Indeed, little information is available about vascular effects of antidepressant drugs in diabetes. METHOD We investigated the effect of chronic administration of fluoxetine "FLU" and imipramine "IMIP" on behavioral, metabolic...

We describe a 57-year-old patient with Turner's syndrome, iron deficiency anaemia and intestinal vascular abnormalities. Colonoscopy revealed 2 widely dilated, tortuous veins in the terminal ileum and several smaller ectatic veins and haemangioma-like malformations throughout the colon. Laparotomy for herniotomy showed only minimal vascular abnormalities of the serosal surface. Patients with Tu...

P ulmonary arteriovenous malformations (PAVMs) and coronary artery fistulas (CAFs) are infrequent clinical problems but can potentially cause significant morbidity and mortality. They are usually congenital, but acquired forms do occur. Treatment of these vascular abnormalities has evolved considerably during the last 2 decades. Percutaneous transcatheter closure of PAVMs and CAFs is now consid...

Vascular malformations include several vascular abnormalities, congenital in most cases, classified according to their dynamic flow characteristics into high-flow and low-flow abnormalities; both types are commonly located in the head and neck region. Imaging modalities such as Echocolor-Doppler, CT, and MRI can be employed in the evaluation of vascular malformations’ in order to describe their...
