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

Figure 3

Cerebral angiography of the patient 2. (a) Embolization of the ruptured sac (arrow). (b) A few rings enter the branch artery to form stable support (pillars of the “stilted building”) (arrow). (c) The aneurysm continues to be filled with the coil, avoiding the branch from the body of the aneurysm (body of the “stilted building”) (arrow). (d) Immediate angiography shows that the ruptured sac and body of the aneurysm are embolized (Class IIIa [9]), and the lumen of the branch artery from the body of the aneurysm is unobstructed (arrow). (e) Five months after interventional surgery, follow-up DSA shows that the aneurysm had not recurred, and the branch lumen from the body of the aneurysm is unobstructed (arrow).
