Clinical and radiological outcomes of mechanical thrombectomy in simultaneous anterior cerebral artery and middle cerebral artery occlusion.

Objective: Simultaneous anterior cerebral artery (ACA) and middle cerebral artery (MCA) occlusion is rare. We investigated the clinical and radiological outcomes of patients with simultaneous ACA and MCA occlusion treated with mechanical thrombectomy.

Methods: We analyzed the clinical and radiological outcomes of 12 patients with simultaneous ACA and MCA occlusion treated with mechanical thrombectomy from January 2018 to December 2020.

Salvage treatment with stenting and temporary balloon occlusion for subarachnoid hemorrhage after stent retrieval following acute proximal M3 occlusion treatment.

Procedure-related subarachnoid hemorrhage (SAH) after mechanical thrombectomy is known to be a clinically benign presentation. However, the treatment in the presence of definite contrast leakage without vessel rupture is controversial. Here, we report a case in which a salvage technique was performed for procedure-related SAH after mechanical thrombectomy for a proximal M3 occlusion.

Differences between proximal and distal M1 occlusions after mechanical thrombectomy.

Purpose: Whether M1 occlusions proximal (pM1) and distal (dM1) to the lenticulostriate perforators result in different clinical outcomes after mechanical thrombectomy (MT) is unknown. We retrospectively compared the clinical outcomes and baseline characteristics of patients with these two types of occlusions.

Methods: From March 2010 to May 2019, we performed MT for 141 M1 occlusions, including pM1 occlusions (n = 58) and dM1 occlusions (n = 83).

Differences in thromboembolism after stent-assisted coiling for unruptured aneurysms between aspirin plus clopidogrel and ticagrelor.

Purpose: To reduce procedural thromboembolisms, tailored antiplatelet drug preparation has been used according to antiplatelet resistance for endovascular coiling of unruptured aneurysms. We compared an aspirin plus clopidogrel group with a ticagrelor group using diffusion-weighted imaging (DWI) after stent-assisted coiling for unruptured aneurysms.

Methods: From October 2018 to April 2019, 72 patients with 78 aneurysms underwent stent-assisted coiling, with aspirin plus clopidogrel (n = 20 patients with 22 aneurysms) or ticagrelor (n = 52 patients with 56 aneurysms) as an antiplatelet preparation, and were enrolled in our study.

An investigation of thalamic nuclei volumes and the intrinsic thalamic structural network based on motor subtype in drug naïve patients with Parkinson's disease.

Introduction: This study aimed to investigate the alterations in thalamic nuclei volumes and the intrinsic thalamic structural network in patients with de novo Parkinson's disease (PD) based on their predominant symptoms.

Methods: We enrolled 65 patients with de novo PD (44 patients with tremor-dominant [TD] subtype and 21 patients with postural instability and gait disturbance [PIGD] subtype) and 20 healthy controls. All subjects underwent three-dimensional T1-weighted magnetic resonance imaging.

Hybrid mechanical thrombectomy for acute ischemic stroke using an intermediate aspiration catheter and Trevo stent simultaneously.

Purpose: To overcome the limitations of traditional mechanical thrombectomy (MT), including catheter aspiration and stent retrievers, such as thrombus fragmentation or migration, we designed hybrid MT using an intermediate aspiration catheter and a Trevo stent simultaneously. We retrospectively compared hybrid MT with the traditional MT.

Methods: From January 2017 to January 2019, we performed MT on 91 occlusions, including internal carotid artery bifurcation (n = 17), M1 segment (n = 53) and M2 segment (n = 21), using hybrid MT (n = 42) and traditional MT (n = 49).

Unexpected abnormal intraoperative neurophysiologic monitoring change by multiple spontaneous intracerebral haemorrhage during endovascular coiling.

We report a patient with multiple angiographically negative intracerebral haemorrhages, which were recognized by significant changes in intraoperative neurophysiologic monitoring during the coil embolization of a left middle cerebral artery aneurysm.

Thrombectomy in acute vertebrobasilar occlusion: a single-centre experience.

Purpose: Acute vertebrobasilar occlusion (VBO) has a grave clinical course; however, thrombectomy in VBO patients has rarely been reported. We retrospectively evaluated the clinical and radiological outcomes of thrombectomy in VBO patients.

Methods: From March 2010 to December 2017, 38 patients with 40 acute VBOs underwent thrombectomy at our hospital.

Transient neurological deterioration due to watershed shift after STA-MCA bypass surgery in acute atherosclerotic occlusion.

Superficial temporal artery (STA)-middle cerebral artery (MCA) bypass surgery is considered not the primary but the last treatment option for acute atherosclerotic occlusions refractory to medical treatment. We retrospectively evaluated patients who underwent STA-MCA bypass surgery for acute atherosclerotic occlusion intractable to other treatments. From June 2010 to May 2014, 10 patients underwent STA-MCA bypass surgery for acute atherosclerotic occlusion at our hospital.

Contralateral Mechanical Thrombectomy of Partial Deployed Stent Retrieval for Acute Anterior Inferior Cerebellar Artery Occlusion.

Background: Acute anterior inferior cerebellar artery (AICA) occlusion is considered an acute ischemic stroke requiring medical treatment without mechanical thrombectomy (MT). There is a procedural risk of parent vessel rupture, but neurologic deficits are not generally severe. Here, we report a case of MT performed using partially deployed stent retrieval for acute AICA occlusion.

Angiographic and clinical outcomes of non-patent anastomosis after bypass surgery in adult moyamoya disease.

Background: The clinical and radiologic outcomes of symptomatic adult moyamoya disease (MMD) patients who have an occluded anastomosis immediately after bypass surgery are poorly studied. The clinical and angiographic outcomes of non-patent anastomosis in symptomatic adult MMD patients were retrospectively reviewed.

Methods: From August 2011 to November 2016, 31 revascularization surgeries, consisting of direct and indirect bypass, were performed on 29 adult MMD patients.
