Insights
Developmental venous anomalies (DVA) and cavernous malformations (CM) can cause brain bleeds. Hemorrhagic DVA often occur in the cerebellum and have milder symptoms than CM, suggesting DVA as a likely cause of cerebellar hemorrhage.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Developmental venous anomalies (DVA) and cavernous malformations (CM) are common cerebral vascular malformations.
- Distinguishing between DVA and CM is crucial, especially when they cause intracerebral hemorrhage (ICH).
Purpose of the Study:
- To compare the demographic, clinical, and radiological features of ICH caused by DVA versus CM.
- To identify differentiating factors for hemorrhagic DVA and CM.
Main Methods:
- Retrospective review of 1706 patients with acute spontaneous ICH between May 2008 and May 2013.
- Identified 10 cases of DVA-induced ICH and 42 cases of CM-induced ICH.
- Compared patient demographics, clinical presentation, neurological deficits, and radiological findings.
Main Results:
- No significant differences in age or sex between DVA and CM groups.
- DVA-induced ICH showed a predilection for the cerebellum (p=0.000) and less severe neurological deficits (p=0.008) compared to CM.
- Hemorrhagic DVA were predominantly cerebellar, while hemorrhagic CM were mainly in the brainstem.
Conclusions:
- Infratentorial hemorrhagic DVA are associated with cerebellar predominance and a generally benign clinical course.
- Cerebellar hemorrhage, particularly in young adults, should raise suspicion for DVA over CM.
- Understanding these differences aids in accurate diagnosis and management of vascular malformation-related hemorrhages.
Abstract:
Developmental venous anomalies (DVA) and cavernous malformations (CM) are a common form of mixed vascular malformation. The relationship between DVA, CM and hemorrhage is complicated. It is important to differentiate hemorrhagic CM and hemorrhagic DVA. A retrospective review of all patients with acute spontaneous intracerebral hemorrhages (ICH) between 1 May 2008 and 1 May 2013 was performed. ICH due to DVA or CM were identified and compared for demographic features, clinical symptoms, neurological deficits, and radiological findings. A total of 1706 patients with acute spontaneous ICH were admitted to our hospital during the study period. Among these, 10 (0.59%) were caused by DVA and 42 (2.47%) were caused by CM. No significant differences were found in age (p=0.252) or sex ratio (p=1.000) between the two groups. Compared with CM-induced ICH, DVA-induced ICH were characterized by cerebellar predominance (p=0.000) and less severe neurological deficits (p=0.008). Infratentorial hemorrhagic DVA are characterized by cerebellar predominance and benign clinical course. Infratentorial hemorrhagic CM are mainly located in the brainstem. DVA should be given suspected rather than CM when considering the etiology of a cerebellar hemorrhage, especially in young adults.
