Investigation of Fluoroscopy Time and Radiation Dose by the Number of Cerebral Angiography Operator Experiences.

Objective: We investigated the fluoroscopy time (FT) and radiation dose by the number of cerebral angiography (CA) operator experiences to clarify the learning curve of CA.

Methods: The subjects were cases for whom CA was performed at our hospital for 5 years between April 2015 and March 2020. Based on the number of CA operator experiences, they were classified into four groups: 1-50 cases (group A), 51-100 cases (group B), 101-200 cases (group C), and 201 cases and later (group D).

Comparison of Treatment Results by Coil Embolization Procedures for Ruptured Cerebral Aneurysms.

Objective: In coil embolization of ruptured cerebral aneurysms, intraoperative cerebral aneurysm re-rupture and thromboembolism are of concern. A good embolic condition can be expected by adjunctive techniques, but there is an increased risk of complications. We investigated the treatment results by coil embolization procedures for ruptured cerebral aneurysms.

The Usefulness of Prasugrel as Rescue Medication in Neuroendovascular Therapy.

Objective: In neuroendovascular therapy, clopidogrel resistance and thrombosis are common problems. In such cases, we use prasugrel as rescue medication, and we clarified its usefulness.

Methods: We retrospectively investigated 199 consecutive cases of neuroendovascular therapy performed at our hospital from April 2016 to March 2018, and examined the safety and effectiveness of prasugrel.

[Are Localized Lesions in the Common Carotid Artery a Risk Factor for Recurrence of Ischemic Stroke in Patients with Symptomatic Carotid Artery Stenosis?].

Background And Purpose: Various studies have addressed risk factors for recurrence of ischemic stroke in patients with symptomatic carotid artery stenosis. However, no investigations have compared common localized carotid artery lesions and internal carotid artery lesions, including carotid bifurcation. This retrospective study investigated risk factors for ischemic stroke recurrence in patients with symptomatic carotid artery stenosis, including a comparison of lesion sites.

A rare case of esophageal cancer (T2N0) with a solitary cerebellar metastasis.

A 72-year-old man with a history of distal gastrectomy was diagnosed with esophageal cancer (EC). A subtotal esophagectomy and the residual total gastrectomy were performed via a right-sided thoracotomy and laparotomy with D2 lymph node dissection followed by reconstruction with a retrosternal right colonic interposition. The pathological diagnosis was Mt, 65 mm, moderately differentiated squamous cell carcinoma, pT2, ly0, v2, pN0, sM0, pStage II.

Spinal chronic subdural hematoma in association with anticoagulant therapy: a case report and literature review.

Study Design: A case of spinal chronic subdural hematoma (SCSDH) in association with anticoagulant therapy was treated surgically.

Objective: To clarify the etiopathogenesis, clinical presentation, and surgical outcomes of SCSDH.

Summary Of Background Data: Intracranial chronic subdural hematoma is a well-recognized complication of anticoagulant therapy.
