Clinical Follow-up of Coil-embolized Ruptured Saccular Cerebral Aneurysms

Surgery for Cerebral Stroke (2008)

Soshi Okamoto Makoto Sonobe Yasunobu Nakai Noriyuki Kato Takashi Shimizu

We have treated ruptured aneurysms with Guglielmi Detachable Coils (GDC) as the first treatment. Of 575 patients of subarachnoid hemorrhage admitted to our hospital between March 1997 and December 2006, the condition of 201 patients was too poor to be treated. Eighty-eight patients were treated by neck clipping, and 286 cases were treated by GDC embolization. Among the latter patients, 229 (80%) were independent on discharge. During the follow-up period, aneurysmal rerupture occurred in 3 cases (1.5%). And 67 cases (33%) showed change of embolization status. We performed second embolizations in 34 cases (13%) to prevent aneurysmal rerupture. These results suggest that embolization was safe and reliable. But new devices may be necessary to achieve more stable embolization status.

Investigation of increase of the serum procalcitonin levels in the acute phase in trauma patients

Nihon Kyukyu Igakukai Zasshi Journal of Japanese Association for Acute Medicine (2014)

Masahiro Harada Hiroshi Uenohara Kyoichi SUGITA Takaaki Kikuno Yuichi Koido

【目的】プロカルシトニン(PCT)は全身性感染症,とくに細菌感染症で上昇するといわれているが,一方で外傷などでも受傷後早期に上昇する例が報告されている。そこで,外傷患者における受傷後早期PCTを調査し,外傷部位や外傷の重症度,在院転帰との関連を調査した。【対象と方法】2010年4月1日から2012年2月28日までに国立病院機構の11箇所の救命救急センターを受診し,入院を要した外傷患者を対象とした。重症度,来院時(Day0)および来院後12 ~24時間(Day1)のバイタルサイン,CRPとPCTを記録し,外傷部位や外傷重症度とPCTとの関連について単変量解析を用いて検討し,また在院転帰とPCTの関係について多変量解析を用いて検討した。【結果】218名の患者が登録された。Day0とDay1のCRPとPCTを比較するとほとんどの部位の外傷においてDay1で有意な上昇を認めた。ISS(injury severity score)別にみてみるとDay1のPCTはISSが高値になるほど高くなった。Day1のPCTは頭部,四肢,多発外傷で有意にISS>20群で高くなった。在院転帰に関して調査項目の比較検討を行ったところ,GCSおよびDay1のPCTで有意差を認めた。頭部外傷患者に絞ってロジスティック回帰分析を行ったところ,GCSおよびDay1のPCTが説明変数として選択され,両者を組み合わせたROC曲線下面積は0.98309であった。【結語】外傷患者のDay1のPCTは,頭部,四肢,多発外傷では外傷の重症度が高いほど高値となる。また頭部外傷患者では,GCSとDay1のPCTを組み合わせることで,予後予測に有用である可能性がある。

Carotid Artery Stenting by GuardWire and Wallstent RP

Surgery for Cerebral Stroke (2011)

Yoshiro Ito Makoto Sonobe Noriyuki Kato M Oohashi Koji Hashimoto

In our institute, carotid artery stenting (CAS) has been performed using GuardWire and Wallstent RP, regardless of plaque pathology. In this study, we evaluated our results (high-intensity area on diffusion-weighted imaging (DWI), stroke/death/myocardial infarction within 30 days, ipsilateral stroke/neurological death after 31 days, and retreatment after CAS). Between April 2005 and December 2009, 76 CAS procedures were performed on 74 patients. DWI obtained after CAS showed a high-intensity area in 13 of 75 procedures (17.3%). Two patients (2.6%) died of stroke and myocardial infarction within 30 days after CAS. One patient (1.3%) had symptomatic cerebral infarction; the other, intracranial hemorrhage. Ipsilateral stroke and neurological death after 31 days occurred in 1 patient (1.3%), who had ipsilateral cerebral infarction at 24 months. Retreatment after CAS was required in 2 patients (2.6%). CAS performed using GuardWire and Wallstent RP is an effective and safe procedure. It is important to achieve proficiency in the use of technical devices to perform successful CAS.

Predictors of Angiographic Changes in Neck Remnants of Ruptured Cerebral Aneurysms Treated With Guglielmi Detachable Coils

Neurologia medico-chirurgica (2006)

Tomosato Yamazaki Makoto Sonobe Yasunobu Nakai Kyoichi SUGITA Yuji Matsumaru

The angiographic changes in neck remnants of ruptured cerebral aneurysms treated with Guglielmi detachable coils (GDCs) were evaluated in the acute stage to analyze the important radiological and clinical factors. The clinical and radiological data of 37 patients with a residual neck of a ruptured cerebral aneurysm treated with GDC were reviewed. The angiographic changes on follow-up angiography were classified into three groups: recanalization of the neck remnant, progressive thrombosis, and unchanged. The effects of the clinical and angiographic findings, such as patient age, follow-up period, type of aneurysm (terminal type or side wall type), dome diameter, neck size, dome/neck ratio, obliteration rate, and volume embolization ratio were investigated. Recanalization of the neck remnant was observed in 18 of 37 cases, progressive thrombosis in nine, and unchanged in 10. The type of aneurysm, dome diameter, neck size, and volume embolization ratio were correlated with changes in the neck remnant. The aneurysm dome diameter and type of aneurysm were independent predictive factors for the recanalization of neck remnants on follow-up angiography. Dome diameter of less than 4.5 mm and volume embolization ratio of more than 31% in side wall aneurysms were likely to lead to progressive thrombosis.

A Case of Cervical Spondylosis presenting Meralgia Paresthetica-Like Symptoms

Spinal Surgery (2005)

Kyoichi SUGITA Kazuhiro Nakamura Noriyuki Kato Yasunobu Nakai Soshi Okamoto

A 42-year-old man suffering from not only meralgia paresthetica-like symptom at bilateral thigh for 8 months but paraparesis after lumbar surgery for L5/S disc hernaition was admitted to our hospital. MRI and CT scan revealed an anterior cervical spinal cord compression at C5/6 level by a horn-like osteophyte in addition to the disc herniation at the same level. The patient was successfully treated by an anterior decompression for the cervical disease to be free of both meralgia-like paresthesia and paraparesis.

Familial Association of Basilar Bifurcation Aneurysm and Moyamoya Disease-Four Case Reports-

Neurologia medico-chirurgica (2003)

Hiroyoshi Akutsu Makoto Sonobe Kyoichi SUGITA Yasunobu Nakai Akira Matsumura

Four patients presented with familial intracranial aneurysms and familial moyamoya disease, including one patient with both familial intracranial aneurysm and moyamoya disease. Basilar bifurcation aneurysms were present in two patients, moyamoya disease in one, and both basilar bifurcation aneurysm and moyamoya disease in one. These events are most likely to arise from different genetic abnormalities associated with basilar bifurcation aneurysm and moyamoya disease.
