Single Center Experience With Pipeline Stent: Feasibility, Technique, and Complications

BACKGROUND: Endovascular coil embolization is an established method of treatment for intracranial aneurysms. The pipeline embolization device (PED) is a low-porosity endovascular stent designed to reconstruct the parent artery and decrease blood flow into the aneurysm. OBJECTIVE: To report a series of 36 patients treated with the PED. METHODS: Thirty-six patients underwent PED placement for aneurysm at the Jefferson Hospital for Neuroscience from October 2010 to November 2011. Clinical charts were reviewed. RESULTS: Thirty-six patients with 42 aneurysms were treated (3 male; 33 female; ages, 34-82; mean age, 60.1 years). Forty-one aneurysms were located in the anterior circulation, whereas one was located at the vertebrobasilar junction. PED placement was successful in all patients and resulted in stasis within all treated aneurysms. Symptomatic postoperative complications were witnessed in 13.9% (n = 5) of patients. These complications included intracerebral hemorrhage (n = 4), dissection (n = 1), symptomatic stroke (n = 2), and death (n = 1). CONCLUSION: Treatment of simple or complex intracranial aneurysms with PEDs alone or in conjunction with coil embolization is technically feasible, and the deployment technique requires a high degree of endovascular skills. Major perioperative adverse events must be studied. Respect for the indications of the procedure is crucial to justify the risk.
