Intraarterial urokinase for thrombus migration after mechanical thrombectomy for large vessel ischemic stroke.

Background: Achieving rapid and complete reperfusion is the ultimate purpose for ischemic stroke with large vessel occlusion (LVO). Although mechanical thrombectomy (MT) had been a proverbially important procedure, medium vessel occlusion (MeVO) with thrombus migration can sporadically occur after MT. Moreover, the safe and effective approach for such had been unknown.

Familiarization with Contact Aspiration using Non-Penetrating of the Thrombus (CANP) Technique as the Initial Procedure for Acute Ischemic Stroke.

Objectives: This study aimed to prove the safety and efficacy of the contact aspiration using non-penetrating of thrombus (CANP) technique for the initial procedure for acute ischemic stroke and to increase operator familiarization with the technical aspects of the CANP technique.

Materials And Methods: A total of 103 patients with large-vessel stroke who were treated using thrombectomy alone at our institution between April 2019 and March 2021 were included in this study. CANP technique was performed using a large lumen catheter (inner diameter, ≥0.

Use of flexible endoscopic aspiration for an intraventricular small floating clot with hemorrhage: a technical note.

Background: Although flexible endoscopy is effective for intraventricular lesions, it is less frequently used for hemorrhagic cases. In some hemorrhagic strokes, blood clots may plunge into the cerebral aqueduct and cause acute obstructive hydrocephalus. A flexible endoscope can aspirate clots and prevent acute hydrocephalus.

Predictors of subacute hematoma expansion requiring surgical evacuation after initial conservative treatment in patients with acute subdural hematoma.

Background: The aim of this study was to clarify the factors associated with requiring subacute surgery in patients with acute subdural hematoma (ASDH) treated conservatively at admission.

Methods: Among the patients with ASDH admitted to our hospital from 2007 to 2018, we retrospectively reviewed data for 200 patients initially treated conservatively. We compared patients' characteristics, medical history, radiological findings, and clinical outcomes and differences between patients undergoing subacute surgery or no surgery.

[Surgical Management of a Thromobotic Extracranial Carotid Artery Aneurysm:A Case Report].

Extracranial carotid artery aneurysms are relatively rare. We present a case involving a giant aneurysm arising from the extracranial carotid artery. The patient was a 79-year-old woman.
