Treatment Options for Cerebrovascular Aneurysms

Cerebrovascular aneurysms, also known as intracranial aneurysms, can occur in various regions of the brain's vascular system. These include the anterior circulation, posterior circulation, internal carotid artery, basilar artery, and the anterior, middle, or posterior cerebral arteries. Aneurysms can develop in any of these vascular areas and may present different challenges depending on their location and size.

Diagnosis and Evaluation

Many aneurysms are asymptomatic and are often discovered incidentally during routine physical exams or imaging tests such as magnetic resonance angiography (MRA) or digital subtraction angiography (DSA). When an aneurysm is detected, it's crucial to assess its location, size, and shape to determine the most appropriate treatment plan. In cases where a patient presents with symptoms caused by a ruptured aneurysm or subarachnoid hemorrhage, urgent evaluation is necessary to prevent life-threatening complications.

Minimally Invasive Treatment: Endovascular Coiling

What is Endovascular Coiling?

In the majority of cases, neurointerventional techniques such as endovascular coiling (balloon-assisted embolization) can be used to treat cerebral aneurysms. This minimally invasive procedure involves guiding a catheter through the blood vessels to the site of the aneurysm, where small coils or balloons are deployed to block blood flow into the aneurysm sac. This helps reduce the risk of rupture or rebleeding and promotes clot formation within the aneurysm.

Open Surgical Treatment: Clipping

When is Surgical Clipping Necessary?

While endovascular coiling is preferred for many patients due to its lower risk profile and faster recovery time, some aneurysms—particularly those with complex anatomy or located in difficult-to-reach areas—may require surgical clipping. During this procedure, a neurosurgeon places a small metal clip at the base of the aneurysm to isolate it from the rest of the blood vessel, preventing further blood flow into the aneurysm.

Choosing the Right Treatment Approach

The decision between endovascular coiling and surgical clipping depends on several factors, including the aneurysm's location and morphology, the patient's overall health, and the expertise of the medical team. Both methods aim to prevent hemorrhage and preserve neurological function, and the best option is tailored to each individual case through a multidisciplinary approach.
