Vertebrobasilar dissecting aneurysms are a common cause of stroke in young adults, often presenting with pain and potentially leading to rebleeding. Early diagnosis and surgical intervention, such as parent artery clipping, are crucial for favorable outcomes.

Area of Science:

  • Neurology
  • Vascular Surgery
  • Radiology

Background:

  • Dissecting aneurysms form when blood penetrates arterial layers, leading to intramural clots and varied clinical presentations.
  • Vertebrobasilar dissecting aneurysms are uncommon but significant vascular lesions.

Observation:

  • Two young patients presented with vertebrobasilar dissecting aneurysms: one with brainstem infarction and another with subarachnoid hemorrhage.
  • Diagnostic confirmation was achieved through helicoidal cerebral angiotomography and angiograms.
  • One patient underwent successful surgical clipping of the posterior communicating artery supplying the dissected segment.

Findings:

  • Dissecting intramural hematomas in the vertebrobasilar territory are a frequent cause of stroke in young individuals.

  • Pain is a primary symptom, often preceding neurological deficits, and minor head trauma may be a trigger.
  • Hemorrhagic presentations carry a high risk of rebleeding and mortality.

    • Implications:

    • Prompt diagnosis and intervention, including microsurgical techniques like parent artery clipping or endovascular methods, are essential.
    • Parent artery clipping demonstrates a low incidence of postoperative ischemic and neural damage.
    • Early identification and management of these unusual lesions are critical for improving patient outcomes.
