transluminal endovascular branched graft placement for a pseudoaneurysm reconstruction of the descending thoracic aorta including the celiac axis
The Journal of Thoracic and Cardiovascular Surgery, 1997Co-Authors: Kanji Inoue, Tomoyuki Iwase, Mitsuru Sato, Yuki Yoshida, Katsuya Ueno, Shunich Tamaki, Ario YamazatoAbstract:We I have previously reported a successful transluminal endovascular placement of a branched graft that had a sidearm extending into the left subclavian artery for repair of type B aortic dissection. The sidearm was properly positioned by catching and pulling back the free end of a detachable Wire attached to its end by means of a gooseneck Snare Wire, which was percutaneously inserted through the left brachial artery. However, it is impossible to place sidearm grafts into the celiac axis and renal arteries in a similar manner. In this article, we describe a new method of inserting a sidearm into the celiac axis and report successful transluminal endovascular repair of a pseudoaneurysm with the use of the branched graft. A 73-year-old man with severe chronic renal failure requiring hemodialysis had previously undergone surgical repair of an aneurysm of the descending thoracic aorta. However, a pseudoaneurysm of the descending thoracic aorta resulting from dehiscence of the suture line at the proximal and distal anastomoses after composite graft surgery had continued to dilate, reaching 80 mm in diameter. Although surgical treatment was attempted, the effort was given up because of marked adhesions caused by a previous thoracotomy. He was admitted to our hospital for endovascular treatment of the pseudoaneurysm. The structure of the Inoue endovascular graft was previously described in detail. 2 The graft was constructed from a Dacron polyester fabric cylinder and the surface was supported by multiple rings of extra-flexible nickel titanium Wire. The patient gave informed consent in conformance with the protocols approved by the institutional review board of Takeda Hospital. Endovascular grafting with the straight graft was performed on June 28, 1995. Although the proximal communication was completely obliterated after the procedure, the distal communication persisted because the distal orifice of the pseudoaneurysm was in close proximity to the celiac axis. Although transluminal embolization was

squid capture modified in situ stent graft fenestration technique for aortic arch aneurysm repair
CardioVascular and Interventional Radiology, 2014Co-Authors: Norio Hongo, Shinji Miyamoto, Rieko Shuto, Tomoyuki Wada, Noritaka Kamei, Aiko Sato, Shunro Matsumoto, Hiro Kiyosue, Hiromu MoriAbstract:An 83-year-old female was found to have an fusiform aneurysm in the aortic arch. She was deemed to be a high surgical risk; therefore, endovascular stent–graft placement followed by revascularization of the brachiocephalic trunk using in situ stent–graft fenestration was considered. However, the safe application of fenestration was deemed difficult due to the tortuosity of the brachiocephalic artery. The patient was successfully treated with the aid of the “squid-capture” technique, which consists of deployment of the stent–graft in a Snare Wire loop that was advanced from the brachiocephalic artery and fenestration of the stent–graft with the support of the loop. A follow-up exam revealed complete sealing of the aneurysm without any complications. The squid-capture technique allows for the safe and secure puncture of the graft.

Foreign Body Removal by Snare Loop: During
2011Co-Authors: Intracranial Stent ProcedureAbstract:We present a case of successful retrieval of an intracranial stent using a Snare Wire. A 52-year-old woman presented with left border zone infarction. On cerebral angiography, the C6 segment of the left internal carotid artery (ICA) showed significant stenosis. We attempted stenting of the lesion, although stent dislodgement occurred in the ICA C4 segment. We successfully removed it using a Snare loop, and there were no complications during the procedure. Key Words: Foreign body; Snare loop; Endovascular procedures Stent detachment and loss from the balloon is one of the complications of intracranial interventional procedures. Embolization of the detached stent is associated with a high risk of intracranial vessel occlusion and subsequent cerebral infarction. Therefore, interventional radiologists may be confronted with the problem of how best to retrieve intravascular foreign bodies, including detached stents [1]. We present a case of successful retrieval of an intracranial stent using a Snare Wire. To our knowledge, this is the first case report of intracranial stent removal
