The low-profile visualized intraluminal support device (LVIS) is a braided stent for stent assist coil embolization for intracranial aneurysms. The LVIS stent has a small stent cell design with higher neck coverage than Enterprise VRD/2 and Neuroform EZ/Atlas. The LVIS stent is applied for parent arteries with diameters ranging from 2.0 to 3.0 mm. In particular, LVIS Jr. enables embolization for distal artery aneurysms with a small parent artery. In this report, the authors reviewed cases of intracranial aneurysm coil embolization using a LVIS stent.
Between September 2015 and September 2016, stent assist embolization with a LVIS stent was performed for 15 patients. LVIS and LVIS Jr. were used in 4 and 11 cases, respectively. In the postprocedural result, complete occlusion was obtained in 12 (80%) of 15 cases and neck remnant was obtained in 3 (20%) of 15 cases.
Clinical complications with neurological deficit were observed in 2 (13%) of 15 cases, including instent occlusion and postoperative subarachnoid hemorrhage. The LVIS stent provided proper coverage of the aneurysmal neck for coiling. Procedural complications without sequelae were observed in 2 (13%) of 15 cases, including stent migration, stuck microcatheter, and flared stent.
LVIS and LVIS Jr. were useful for the stent assist aneurysm embolization; however, appropriate case selection and technical management based on stent characteristics are mandatory.
