Objective: We examined the usefulness of the T-stent technique for a large broad-necked aneurysm at the internal carotid (IC) posterior communicating artery (P-com) bifurcation.

Case Presentation: A 73-year-old female. Detailed examination for cerebral infarction indicated an unruptured cerebral aneurysm. As a fetal-type P-com artery was detected in the aneurysmal dome, coiling with a stent-balloon technique was performed. Finally, embolization using the T-stent technique, in which a stent inserted into the P-com was connected to the side of an IC artery stent, was successful, facilitating the preservation of the P-com.

Conclusion: The T-stent technique, in which stents are not overlapped, may be useful for performing safe, accurate embolization of large broad-necked aneurysms with branching vessels.
