Figure Lengend Snippet: In the case of a ruptured anterior communicating artery aneurysm, the height, width, and neck size of the aneurysm were 2.7, 2.8, and 2.7 mm, respectively. (a) Angiography before embolization. (b) Attempted frame formation using Target Ultra 2.5 mm × 4 cm. Safe frame formation was not possible due to protrusion into the parent artery. (c) A 2.5 mm × 3.5 cm Target Tetra detachable coil (TTDC) was placed through the aneurysmal neck. (d) A 2.0 mm × 2.5 cm TTDC was implanted as the second coil. The aneurysm neck was packed tight. However, the aneurysm tip had a space (arrow). (e) Angiography after completing embolization. The aneurysm, including its tip, had disappeared.

Figure Lengend Snippet: In the case of an unruptured internal carotid artery-paraclinoid medial-type aneurysm, the height, width, and neck size of the aneurysm were 3.0, 4.5, and 3.0 mm, respectively. (a) Angiography before embolization. The balloon catheter was seated on the aneurysm neck. (b) The frame was formed with the first coil. The arrow was a microcatheter tip. (c-f) The Target Tetra detachable coil (TTDC) was implanted deep inside the aneurysm. Each arrow was a gradual kicking back microcatheter tip. The TTDC sizes were 3 mm × 4.5 cm (c), 3 mm × 4.5 cm (d), 2.5 mm × 4.5 cm (e), and 2 mm × 2.5 cm (f). (g) Angiography after completing embolization. The aneurysm had disappeared.

Figure Lengend Snippet: In the case of a ruptured vertebral artery-posterior inferior cerebellar artery aneurysm, the height, width, and neck size of the aneurysm were 3.7, 4.7, and 2.8 mm, respectively. (a) Angiography before embolization. (b) The first coil was implanted with Target 360 Ultra 4 mm × 8 cm. (c) The microcatheter tip perforated the aneurysm during the second coil, with a 3.5 mm × 6 cm Target Tetra detachable coil (TTDC). (d and e) A 2.5 mm × 6 cm TTDC was implanted from the outside of the aneurysm to the inside. However, bleeding was observed (arrow). (f and g) The last coil, which is a 2 mm × 2.5 cm TTDC, stopped the bleeding.

Figure Lengend Snippet: Target tetra detachable coil (TTDC). By maintaining a tetrahedral conformation inside an intracranial aneurysm, it is feasible to treat small aneurysms, which is advantageous, especially during the framing process. In addition, a braided stretch-resistant suture allows for a smoother delivery and reduced microcatheter kickback.

Figure Lengend Snippet: A 59-year-old male patient with an unruptured right posterior communicating artery aneurysm. ( A ) Three-dimensional rotational angiography shows a left posterior communicating artery aneurysm (neck: 5.0 mm, height: 5.8 mm, size: 7.8 × 5.1 mm). ( B ) The Target 360 Ultra coil of the appropriate size was initially selected as the framing coil. However, the coil expanded outside the aneurysmal sac and protruded into the parent artery, obliterating the posterior communicating artery (arrow). A new frame was established using the TTDC.
