Active clinical trials for "Hemangioma"

The goal of this study is to identify genetic alterations resulting in the development of arteriovenous malformation (AVM) in the central nervous system.

This register study will collect the treatment information of the intracranial arteriovenous malformation patients in China. We aim to understand the current treatment situation of the disease in China.

Infant hemangioma(IH) is the most common benign vascular tumor of infancy with the estimated incidence varies 1% to 12%.However, in China, the incidence of infant hemangioma and related epidemiological data remains unclear. So, the investigators designed the study for the following purposes: 1, to aware the incidence of infantile hemangioma and understand the related risk factorsin China; 2, to understand the clinical characteristics of infantile hemangioma and the risk factors for complications; 3, to investigate the level of knowledge, treatment options in infant hemangioma in Chinese doctors; 3, to improve the awareness of infantile hemangioma in parents and provide more advice for pregnancy counseling and eugenics.

Intracranial cavernous vascular malformations are variously known as cavernous angiomas, cavernous hemangiomas, or, more simply, cavernomas. Cavernomas are congenital low flow vascular lesions. It composed of irregular sinusoidal vascular channels, lacking smooth muscle, and elastic fibers. They lack feeding arteries or draining veins and contain no neural tissue. The first description of an intracranial cavernoma was given by Virchow, in 1863. For over a century, it was considered to be an extremely rare malformation, usually found at autopsy, and exceptionally diagnosed during life. The prevalence of cerebral cavernous malformations (CCM) is estimated to be 0.4-0.9%.

In this case, we report a case of atresia syndrome (LIS), a serious neurological disease caused by pulmonary arteriovenous fistula (PAVM). We present a previously healthy middle-aged woman who developed atresia syndrome after severe pontine infarction due to basilar artery occlusion due to undiagnosed arteriovenous malformation. This report reviewed the medical history, post-admission examination and related literature, and concluded that PAVM should be considered as the cause of implicit stroke, especially in young patients with right-to-left shunt, and should be actively treated.
