Stenting After Coiling Using a Single Microcatheter for Treatment of Ruptured Intracranial Fusiform Aneurysms with Parent Arteries Less Than 1.5 mm in Diameter.

BACKGROUND

Ruptured intracranial fusiform aneurysms involving small-diameter parent arteries are difficult to treat. Parent artery occlusion is a relatively simple and reliable treatment. However, occasionally, the parent arteries have to be retained. The arrival of the low-profile stent (LVIS Jr.) has made reconstructive endovascular treatment for fusiform aneurysms involving small-diameter parent arteries possible.

CASE DESCRIPTION

This report describes an innovative method for stent-assisted coiling (stenting after coiling technique using only 1 microcatheter) and describes our initial experience and feasibility of this technique. However, this report carries all limitations of a technical case report of a single patient, including reproducibility, unknown potential of complications, absence of long-term follow-up, and comparative effectiveness or safety with current known techniques.

CONCLUSIONS

Stenting after a coiling technique using the LVIS Jr. stent provides a possible method for reconstructive endovascular treatment of intracranial fusiform aneurysms with parent arteries <1.5 mm in diameter.
