Background:
Dolichoectatic basilar trunk aneurysms are exceedingly rare and carry a poor prognosis. Treatment strategies are often reserved for patients with severe and progressive symptoms.
Case description:
A patient in their 40s with a dolichoectatic basilar trunk aneurysm developed significant progression of the lesion and neurologic decline, necessitating treatment. He underwent flow diversion utilizing multiple telescoping Pipeline Vantage Embolization Devices with Shield Technology for treatment. At 1-year follow-up, the aneurysm was stable in size and the patient remained at his neurologic baseline.
Conclusion:
This case illustrates the need for continued development of next-generation endovascular devices as these aneurysms have limited management options.
