A developmental venous anomaly (DVA, formerly known as venous angioma) is a congenital variant of the cerebral venous drainage. On imaging it is seen as a number of small deep parenchymal veins converging toward a larger collecting vein.
Cavernous hemangioma, also called cavernous angioma, venous malformation, or cavernoma, [1] [2] is a type of venous malformation due to endothelial dysmorphogenesis from a lesion which is present at birth. A cavernoma in the brain is called a cerebral cavernous malformation or CCM.
Developmental venous abnormality seen on a (T1 axial contrast enhanced) MRI. In up to 30% there is a coincidence of CCM with a venous angioma, also known as a developmental venous anomaly . These lesions appear either as enhancing linear blood vessels or caput medusae , a radial orientation of small vessels that resemble the hair of Medusa from ...
Venous malformation is a bluish lesion compressible on palpation; the masses enlarge with physical activity or if in a dependent position. The bluish lesion is caused by dilated venous vessels. Venous malformations can be painful in the morning due to stasis and microthrombi within the veins. Venous malformations usually occur in the head and ...
This is a shortened version of the fourteenth chapter of the ICD-9: Congenital Anomalies. It covers ICD codes 740 to 759. The full chapter can be found on pages 417 to 437 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Non-developmental syndromes also directly or indirectly affect the Great Cerebral Vein of Galen, although they are extremely rare. These include superior vena cava syndrome (SVCS), and thrombosis of the lateral sinus, superior sagittal sinus, internal jugular vein, or of the Great Cerebral Vein of Galen itself. [citation needed]
A vascular malformation is a type of vascular anomaly. [2] They may cause aesthetic problems as they have a growth cycle, and can continue to grow throughout life. Vascular malformations of the brain include those involving capillaries, and those involving the veins and arteries.
Congenital stenosis of vena cava is a congenital anomaly in which the superior vena cava or inferior vena cava has an aberrant interruption or coarctation. In some cases, it can be asymptomatic, [ 1 ] and in other cases it can lead to fluid accumulation and cardiopulmonary collapse.
