What type of aneurysms are most common in intracranial interventions?

Saccular (berry) aneurysms are indeed the most common type of aneurysms encountered in intracranial interventions. These aneurysms typically form at the bifurcations of cerebral arteries and are characterized by their sac-like appearance. Their prevalence in the population and the propensity for rupture make them a significant concern in neurosurgical and interventional radiological practice.

Intracranial saccular aneurysms are of particular interest because they often present with acute complications such as subarachnoid hemorrhage if they rupture, which necessitates urgent intervention. Various techniques, such as endovascular coiling or surgical clipping, may be employed to address these aneurysms.

Understanding the commonality of saccular aneurysms highlights why they are prioritized in terms of diagnostic imaging and intervention strategies in interventional radiology. Knowing this helps practitioners focus on the conditions that are most likely to require their expertise, guiding both treatment plans and patient management protocols effectively.
