Aneurysms at the vertebrobasilar junction are often found with basilar artery (BA) fenestration We encountered 10 consecutive cases of aneurysms associated with BA fenestration The purpose of this study is to describe the frequency, clinical features, and outcome of these aneurysms treated by endovascular procedure The incidence of these aneurysms in our series was 1.9% All aneurysms were successfully treated by coil embolization. Half of them were treated by using simple technique, and the other half were treated by using adjunctive techniques such as balloon remodeling technique. 70% of these cases were ruptured, and all except one case showed good recovery at the time of discharge We found 63 reported cases of this aneurysm in the literature between 2000 and 2012 57 out of 63 aneurysms were treated by endovascular means with good clinical results The usefulness of endovascular procedure is reported to be superior to surgical clipping because of their anatomical complexity and the difficulty of surgical exposure for clipping We conclude that outcome of these aneurysms is favorable and endovascular procedure has become their standard treatment for these aneurysms.

Endovascular treatment for cervical carotid artery aneurysm: A case report Reviewed

Yasuhiko Hattori, Kenji Sugiu, Tomohito Hishikawa, Koji Tokunaga, Kazuya Takahashi, Isao Date

Neurological Surgery 41 ( 6 ) 515 - 523 2013.6

Language：Japanese Publishing type：Research paper (scientific journal)

We report here a case of cervical carotid artery aneurysm. This 37-year-old male suffered from acute neck swelling when he was taking lunch after physical work. Ultrasonography demonstrated a cervical pseudoaneurysm and a jet flow, which was blowing into the dome from the carotid artery. Angiogram revealed an aneurysm with a diameter of 3 cm at the bifurcation of the common carotid artery. Coil embolization using double-catheter technique was performed and complete occlusion of the aneurysm was obtained without any complications. The patient returned to his normal life. Cervical carotid artery aneurysms are rare and they induce pain by swelling in the neck, hoarseness, swallowing disturbance, hemorrhage, and cerebral ischemia due to embolism. In case of a cervical carotid artery aneurysm, safe and effective treatments are required and endovascular treatment should be considered. Although stent-assisted coil embolization or covered-stent placement were reported as an effective treatment for cervical aneurysms, coil embolization without using a stent was performed in this particular patient who is a young, blue-collar worker because the avoidance of long-term anti-platelet therapy was desirable Preoperative evaluation is important to select adequate treatment.

A case of a paraspinal arteriovenous fistula presenting with retroperitoneal hemorrhage treated by staged transarterial and transvenous embolization Reviewed

Atsuhiko Toyoshima, Koji Tokunaga, Hiroaki Manabe, Kenji Sugiu, Masafumi Hiramatsu, Hisakazu Itami, Tomohito Hishikawa, Isao Date

Neurological Surgery 41 ( 5 ) 429 - 435 2013.5

Language：Japanese Publishing type：Research paper (scientific journal)

We report a rare case of a paraspinal arteriovenous fistula (AVF) treated by combined transarterial and transvenous embolization (TAE/TVE) A 72-year-old woman was admitted after a traffic accident. Abdominal enhanced CT disclosed pre-existing large varices at the L3-L4 level in the right retropentoneum with multiple feeding arteries and veins draining into the extradural venous plexus in the spinal canal. The lesion was diagnosed as a paraspinal AVF. Four days later, the patient went into a state of shock. Emergency abdominal CT showed retroperitoneal hemorrhage due to rupture of the varix. TAE of the feeders from the right L1-L4 arteries was performed, and rebleeding from the varix was prevented. Three months later, follow-up CTA showed regrowth of the AVF, and TVE was performed. Two microcatheters were navigated transveriously into the varix, and detachable coils were delivered into the small compartment just downstream to the shunts, leading to complete obliteration. We conclude that transarterial flow reduction followed by occlusion of the venous side of the shunts is effective to achieve cure of a complex and high-flow paraspinal AVF.

Surgical and endovascular treatment for superior cerebellar artery aneurysms: Report of two cases Reviewed

Jun Haruma, Kenji Sugiu, Yosuke Shimazu, Hiroyuki Michiue, Koji Tokunaga, Isao Date

Neurological Surgery 41 ( 1 ) 45 - 51 2013.1

Language：Japanese Publishing type：Research paper (scientific journal)

Aneurysms located on the supenor cerebellar artery (SCA) are uncommon and their presentation, natural history, and clinical management are poorly understood. Reports related to the endovascular or surgical management of SCA aneurysms are rare Herein, we report two cases of SCA aneurysm The first is that of a 70-year-old woman who presented with subarachnoid hemorrhage (SAH). Surgical treatment (neck clipping) of the ruptured SCA aneurysm was performed, and the flow of the parent artery disappeared. The second is that of a 69-year-old woman with an unruptured SCA aneurysm who underwent endovascular surgery to occlude the parent artery. Neither patients exhibited any additional neurological deficits SCA aneurysms often have either relatively wide or undefinable necks, so it is difficult to preserve the parent artery. According to several surgical reports, occlusion of the SCA appears well tolerated for a vanety of reasons.

Endovascular coiling of thrombosed basilar tip aneurysm using double stents in a Y-configuration Reviewed

Yoshihiro Otani, Kenji Sugiu, Koji Tokunaga, Tomohito Hishikawa, Hisakazu Itami, Masafumi Hiramatsu, Yu Okuma, Isao Date

Neurological Surgery 40 ( 11 ) 1005 - 1012 2012.11

Recent advances in endovascular techniques greatly improved the ability to treat complex cerebral aneurysms. However, patients with wide-necked cerebral aneurysms have posed a special challenge to conventional endovascular therapy. We report a novel method of embolizing wide-necked basilar apex aneurysms by employing a Y-configuration, double stent technique. A 40-year-old woman with a partially thrombosed basilar apex aneurysm transferred to our hospital after diagnosis of subarachnoid hemorrhage. Cerebral angiography revealed a wide-necked aneurysm which neck was incorporating the origins of both the posterior cerebral arteries. In treatment procedure, a microcatheter was inserted into the aneurysm followed by coiling of the upper half of the dome. Next, the first stent was deployed in the right P2 segment extending down to the mid basilar artery and the second stent was then deployed with half of the stent in the left P2 and the other half within the lumen of the previously placed stent. Finally, the microcatheter was withdrawn near the neck, and the rest of the aneurysmal dome was packed by additional coils. The result was favorable. Successful coil embolization of a widenecked bifurcation aneurysm can be achieved by using the double stenting Y-configuration in this case. This result continues to provide highly encouraging support of this novel technique to treat a subset of complex, wide-necked aneurysms that until recently were considered poor candidates for endovascular therapies.
