The Application of “Stilted Building” Technique in the Embolization of Aneurysms with Secondary Branches

Figure 2

Cerebral angiography of the patient 1. (a–c) DSA examination revealed that a right posterior communicating ruptured aneurysm and the embryonic posterior cerebral artery originated from the neck of the aneurysm. (d) The first coil forms a stable support frame, and a few rings entered the posterior communicating artery to provide support (the pillars of the “stilted building”) (arrow). (e) The aneurysm continues to be embolized, and angiography shows that the ruptured sac is densely embolized (arrow). (f) To embolize the aneurysm body, the detaining effect of the frame was leveraged to adjust the position of the coils and avoiding the branch artery (body of the “stilted building”) (arrow). (g) Immediate angiography shows that the ruptured sac and body of the aneurysm are embolized. The lumen of the communicating artery is unobstructed (arrow). (h, i) Seven months after interventional surgery, follow-up DSA shows no recurrence of the aneurysm, and the lumen of the posterior communicating artery is unobstructed (arrow).
