An evaluation of immediate sheath removal and use of the Angio-Seal vascular closure device in neuroradiological interventions

Abstract

We set out to assess the effect of using an arteriotomy closure device in patients at high risk of access site complications. One-hundred nineteen patients with femoral artery access were prospectively included in five centers in France (56 males, 63 females, age range 20-84 years). The neurointerventional procedures were embolization of intracranial aneurysm (71.4%), carotid angioplasty (11.8%), cerebral angioplasty (1.7%), thrombolysis (0.8%), and other procedures (14.3%). Sheaths were removed and the closure device deployed immediately postprocedure. One patient developed a false aneurysm, and one developed a small hematoma. Neither required treatment. Postdevice deployment bleeding was experienced in three patients (2.5%), requiring minimal management. There were no major complications. Three patients died of causes unrelated to the vessel closure. Patient comfort was 2.2 on a scale of 1 (none) to 10 (severe). The results showed that immediate sheath removal followed by use of the closure device is safe in patients undergoing neurointerventional procedures and offers a low level of patient discomfort. In selected patients, early hospital discharge was possible.
