Background: Detection of intracranial aneurysms (IAs) is a time consuming and error prone process. Therefore, solutions that can localize IAs with high sensitivity are required. Several artificial intelligence (AI)-based automated diagnoses on medical images have recently been reported. We aimed to develop an diagnosis system for the location maximum diameter MRI in present study. Methods: In 1310 patients or without IAs, 937 MRIs were used training data 373 cases test data. The definition...
Objective: The growth of unruptured intracranial aneurysms (IAs) is regarded as a critical precursor to aneurysmal rupture. Accurately predicting aneurysm crucial for appropriate therapeutic interventions prevent rupture in high-risk aneurysms. UCAS Japan score has been widely used risk assessment Japan; however, its relationship unclear. present study aimed examine whether the can accurately predict and develop novel prediction system using artificial intelligence (AI)-based machine...
Acquired coagulopathy is uncommon. Cases of hemophilia A, which characterized by reduced coagulation factor Ⅷ, have been reported but cases involving diminished factors VII, Ⅺ, or XII not reported. We report the case a patient who presented with chronic subdural hematoma (CSDH), was challenging to treat due underlying acquired abnormalities. Middle meningeal artery (MMA) embolization promising approach for managing refractory CSDH and has proved effective in this case. An 82-year-old man no...
Background and purpose Intracranial aneurysm growth is a significant risk factor for rupture; however, few aneurysms remain unruptured long periods, even after growth. Here, we identified hemodynamic features associated with aneurysmal rupture Materials methods We analyzed nine middle cerebral artery that grew during the follow-up period using computational fluid dynamics analysis. Growth patterns of were divided into homothetic (Type 1), de novo bleb formation 2), enlargement 3)....
Background A low-profile visualized intraluminal support (LVIS) device may incompletely expand during stent deployment in tortuous vessels. However, the cause of incomplete expansion remains uninvestigated. We aimed to examine vitro factors causing LVIS by using various vessel models. Methods linear model group was created connecting silicone tubes (inner diameter 4 mm) at both sides with different curvature angles 10–140° 10° intervals. For comparison, proximal and distal bending groups...
There have been many reports on the clinical, radiographic, and surgical management of thoracolumbar burst fractures attributed to high-energy trauma. Interestingly, few described how extract bone fragments associated with these injuries protruding into spinal canal contributing significant neurological deficits.An 18-year-old male presented a severe L3-level paraparesis (i.e., loss motor/sensory function below L3 lower extremity hyporeflexia, sphincter dysfunction: American Spinal Injury...
Objective: Iatrogenic artery dissection during reperfusion therapy is one of the complications causing a poor prognosis. We report two cases emergent stent placement for iatrogenic cervical carotid acute ischemic stroke.
Objective: We report a case of low-profile visualized intraluminal support device (LVIS) being deployed and protruded into an aneurysmal neck in barrel-like shape to perform dense coil embolization while preserving the branch vessel from dome order prevent enlargement.
Objective: We report a survived case of acute bilateral internal carotid artery occlusion successfully treated by mechanical thrombectomy.

当センターにおいて手術治療を行った高位腰椎椎間板ヘルニア67例に関して, 臨床症状, 神経症候, 治療法の変遷について後方視的検討を行った. 症状・症候としては鼠径部, 大腿前面部に疼痛・しびれが分布することが多く, 足関節以遠のしびれや下肢腱反射亢進を伴うこともあった. 手術用顕微鏡下の腰椎椎間板ヘルニア摘出術は, L1/2レベルのヘルニアで実施される頻度はかなりまれであったが, L2/3レベルでは約半数はこの術式にて治療されていた. ここ5, 6年で治療法は大きく変化しており, 内視鏡下手術, コンドリアーゼ注入療法は今後の治療の選択肢となり得ることが予想された.
Objective: We report a case in which two coils became stuck microcatheter at the end of coil embolization for cerebral aneurysm.
Background: Appropriate preoperative patient evaluation and careful perioperative management are important to perform carotid artery stenting (CAS) safely. We aimed investigate the usefulness of a checklist procedural routine.
