Mechanical Thrombectomy for Patients with Occlusions in Both the Anterior Cerebral Artery and Middle Cerebral Artery: Case Series and Review of the Literature.

Objective: Most large-vessel occlusions (LVOs) amenable to acute recanalization occur in the internal carotid or middle cerebral artery. However, few LVOs with a multivessel disease can be difficult to treat. This study aimed to determine the outcomes of mechanical thrombectomy in patients with both anterior and middle cerebral artery occlusions.

Sequential Symptomatic Arterial Dissections in Multiple Vascular Beds in a Patient with Fibromuscular Dysplasia.

A 60-year-old man was admitted to our hospital because of abdominal pain and disturbed consciousness. Head magnetic resonance imaging showed right vertebral artery dissection and abdominal enhanced computed tomography showed dissection of the superior mesenteric artery. The patient was diagnosed as having fibromuscular dysplasia (FMD) based on conventional angiography.

Blood flow disturbance in perforating arteries attributable to aneurysm surgery.

Object: The object of this study was to investigate patients with cerebral infarction in the area of the perforating arteries after aneurysm surgery.

Methods: The authors studied the incidence of cerebral infarction in 1043 patients using computed tomography or magnetic resonance imaging and the affected perforating arteries, clinical symptoms, prognosis, and operative maneuvers resulting in blood flow disturbance.

Results: Among 46 patients (4.

Primary squamous cell carcinoma of the breast: a case report.

Primary squamous cell carcinoma of the breast is a rare entity. We treated a 55-year old woman who came to us with bleeding from the left breast tumor. The tumor was 7 x 8 x 10 cm in size with ulceration and surgical biopsy results showed it to be squamous cell carcinoma of the breast, while metastatic work-up findings ruled out other sources of primary tumor.

Intraoperative monitoring of blood flow insufficiency during surgery of middle cerebral artery aneurysms.

Object: The usefulness of motor evoked potential (MEP) monitoring to detect blood flow insufficiency (BFI) in the cortical branches of the middle cerebral artery (MCA) and lenticulostriate arteries (LSAs) during MCA aneurysm surgery was investigated based on the correlation between MEP and somatosensory evoked potential (SEP) monitoring.

Methods: Fifty-three patients with MCA aneurysms underwent surgery accompanied by intraoperative MEP and SEP monitoring. There was no postoperative motor paresis in 43 patients in whom MEP and SEP results remained unchanged.

3D-CT arteriography and 3D-CT venography: the separate demonstration of arterial-phase and venous-phase on 3D-CT angiography in a single procedure.

Although 3D-CT angiography provides valuable anatomic information regarding lesion and their surrounding vessels and bony structures, it cannot demonstrate lesions, arteries, and veins, separately. The separate demonstration of arterial-phase 3D-CT angiography (3D-CT arteriography) and venous-phase 3D-CT angiography (3D-CT venography) will facilitate the understanding of the vascular anatomy within lesions, thus, allowing improvement of diagnostic accuracy and potentially a safer surgical approach. We describe 3D-CT arteriography and 3D-CT venography by using a multidetector row helical CT.

Expression of Mg2+-dependent, HCO3- -stimulated adenine triphosphatase in the human duodenum.

Background And Aim: Mg2+-dependent, HCO3- -stimulated adenine triphosphatase (Mg2+-HCO3- -ATPase) is an enzyme that catabolizes ATP in the presence of HCO3- and Mg2+. The activity of this ATPase is known to be present in the duodenum, but its physiological role remains unclear. In the present study, the aim was to study the distribution and biochemical profiles of Mg2+-HCO3- -ATPase in the human duodenum.

Acute aneurysm surgery using three-dimensional CT angiogrphy without conventional catheter angiography.

The object of this study is to assess whether aneurysm surgery can be performed in patients with ruptured cerebral aneurysms by using three-dimensional computerized tomography angiography (3D-CTA) alone, without conventional catheter angiography (CCA). Between May 1994 and November 1996, a consecutive series of 60 cases of ruptured cerebral aneurysms was evaluated by both 3D-CTA and CCA prospectively and compared the detectability of cerebral aneurysms. Both 3D-CTA and CCA demonstrated a 100% diagnostic accuracy of ruptured cerebral aneurysms.

Intraoperative monitoring of blood flow insufficiency in the anterior choroidal artery during aneurysm surgery.

Object: The lack of a specified intraoperative method for monitoring anterior choroidal artery (AChA) blood flow insufficiency (BFI) led the authors to devise a method for checking the BFI in this artery during aneurysm surgery. To this end, the authors relied on the intraoperative motor evoked potentials (MEPs) elicited by electrical stimulation of the hand motor cortex.

Methods: The study population consisted of 108 patients with internal carotid artery (ICA) aneurysms who underwent surgery via a standard frontotemporal craniotomy.
