What is Cerebral Arteriovenous Malformation
Cerebral arteriovenous malformations (AVMs) is a complex vascular abnormalities characterized by abnormal connections between arteries and veins within the brain or the dura mater, respectively. Dr. Santosh B. Patil offers a comprehensive and multidisciplinary approach to managing these challenging conditions, employing advanced techniques and collaborating closely with neurosurgical experts to ensure optimal patient outcomes.
Symptoms of Cerebral Arteriovenous Malformation
A brain arteriovenous malformation (AVM) may not cause any symptoms until the AVM bursts and bleeds, known as a hemorrhage. In about half of all brain AVMs, a hemorrhage is the first sign of the malformation.
- Seizures
- Headache.
- Muscle weakness or complete paralysis
- Nausea and vomiting
- Numbness or tingling sensation
- Problems with movement, speech, memory, thinking, balance or vision

Endovascular Embolization using Glue/Onyx
Endovascular embolization is a minimally invasive procedure that involves the selective injection of embolic agents directly into abnormal blood vessels supplying the AVM. Dr. Patil utilizes specialized embolic materials such as glue or Onyx to occlude the abnormal vascular connections and redirect blood flow away from the lesion.Glue Embolization
Dr. Santosh Patil carefully navigates microcatheters to the site of the AVM and injects medical-grade glue into the abnormal vessels. The glue solidifies within the vessels, forming a permanent seal and effectively blocking blood flow, thereby promoting the regression of the lesion over time.
Onyx Embolization
Alternatively, Dr. Santosh Patil may opt for Onyx embolization, a liquid embolic agent with unique properties that enable controlled and precise delivery into the target vessels. Onyx gradually solidifies upon contact with blood, allowing for gradual occlusion of the abnormal vasculature while preserving normal blood flow in adjacent vessels.
Surgical Excision
Surgical excision involves the complete removal of the cerebral arteriovenous malformation (AVM) through open surgery. During the procedure, the neurosurgeon carefully dissects around the AVM, isolates the abnormal blood vessels, and removes them from the surrounding brain tissue. Surgical excision is typically recommended for smaller AVMs located in accessible areas of the brain. While effective, surgical excision carries risks such as bleeding, infection, and neurological deficits, and may not be suitable for all patients, especially those with large or deep-seated AVMs.
Stereotactic Radiosurgery
Stereotactic radiosurgery is a non-invasive treatment option for cerebral arteriovenous malformations (AVMs) that utilizes precisely targeted radiation beams to obliterate the abnormal blood vessels. During the procedure, highly focused radiation is delivered to the AVM while minimizing exposure to surrounding healthy brain tissue. Over time, the radiation induces vascular sclerosis and thrombosis within the AVM, leading to its gradual closure. Stereotactic radiosurgery is typically recommended for smaller AVMs or those located in critical or surgically inaccessible areas of the brain. It offers a lower risk alternative to surgical excision, with reduced potential for complications and shorter recovery times.
