Retrospective Observational Study of Patients With Subdural Hematoma Treated With Idarucizumab.

Use of anticoagulants is increasing with the aging of societies. The safe first-line drug is likely to be a direct oral anticoagulant (DOAC), but outcomes of treatment of traumatic brain injury (TBI) with anticoagulants are uncertain. Therefore, we examined the clinical effect of idarucizumab as reversal therapy in elderly patients with TBI who were treated with dabigatran.

Clinical Significance of Stiffness during Endoscopic Surgery for Intracerebral Hemorrhage: A Retrospective Study.

Studies regarding hematoma stiffness and removal difficulty are scarce. This study explored the association between hematoma stiffness and surgical results of endoscopic hematoma removal for intracerebral hemorrhage. It also aimed to clarify factors associated with hematoma stiffness.

Acute epidural vertex hematoma with good hemostasis using delayed surgery after monitoring of coagulation and fibrinolytic parameters: A case report.

Background: The appropriate timing and method of surgery for vertex epidural hematoma (VEDH) are uncertain due to the presentation and slow symptomatic exacerbation caused by bleeding from a venous origin involving the injured superior sagittal sinus (SSS). Coagulation and fibrinolytic disorders that occur after traumatic brain injury also worsen bleeding. For these reasons, it is challenging to decide the surgical procedure and timing of surgery.

Optic nerve sheath diameter as a quantitative parameter associated with the outcome in patients with traumatic brain injury undergoing hematoma removal.

Purpose: To determine the association between optic nerve sheath diameter (ONSD) and outcome in patients with traumatic brain injury (TBI) who undergo hematoma removal (HR).

Methods: This study was a retrospective analysis of data from a single center between 2016 and 2021. Adult patients with TBI who underwent HR within 24 h after admission were included in this study.

Effectiveness of Administration of Fibrinogen Concentrate as Prevention of Hypofibrinogenemia in Patients with Traumatic Brain Injury with a Higher Risk for Severe Hyperfibrinolysis: Single Center Before-and-After Study.

Background: Coagulopathy is often observed in severe traumatic brain injury (sTBI), and hyperfibrinolysis (HF) is associated with a poor prognosis. Although the efficacy of fibrinogen concentrate (FC) in multiple trauma has been reported, its efficacy in sTBI is unclear. Therefore, we delineated severe HF risk factors despite fresh frozen plasma transfusion.

Radiological and clinical features of twig-like middle cerebral artery in comparison with moyamoya angiopathy: a multicenter retrospective study.

Objective: Twig-like middle cerebral artery (T-MCA) is a rare congenital anomaly that is difficult to distinguish from moyamoya angiopathy (MMA), given the similarity of the angioarchitectures. The aim of this study was to gain insights into the radiological and clinical features of T-MCA and to distinguish this condition from MMA.

Methods: A multicenter retrospective study was conducted in 29 patients with T-MCA and 57 patients with MMA.

Super-selective balloon test occlusion with electrophysiological monitoring to occlude angiographically invisible posterior communicating artery perforators with unruptured aneurysm.

Balloon test occlusion (BTO) can predict the ischemic complication risk associated with arterial occlusion. We present a case of an unruptured, broad-necked internal carotid artery-posterior communicating artery (PcomA) aneurysm that was successfully embolized after super-selective BTO of fetal PcomA with electrophysiological monitoring. The proximal portion of the PcomA was internally occluded without causing major neurological deficits, although we observed a small new infarction in the ipsilateral anterior thalamus postoperatively.

FLAIR vascular hyperintensity with DWI for regional collateral flow and tissue fate in recanalized acute middle cerebral artery occlusion.

Purpose: Fluid-attenuated inversion recovery (FLAIR) vascular hyperintensity (FVH) extent or FVH-DWI mismatch as a primary influencing factor of clinical outcome in acute ischemic stroke is controversial. This study elucidated the regional pathophysiology and tissue fate in four types of cortical territories classified by the initial FVH and DWI findings in patients with acute proximal middle cerebral artery (M1) occlusion successfully recanalized using mechanical thrombectomy.

Methods: We retrospectively evaluated 35 patients successfully recanalized within 24 h of acute M1 occlusion onset between 2016 and 2019.

Early treatment of progressive vertebral arteriovenous fistula caused by cervical penetrating injury.

Background: Penetrating injury of the vertebral artery (VA) is uncommon because it lies deep in the neck and is surrounded by a bony foramen. Vertebral-venous fistula is a rare vascular condition in which there is direct aberrant communication among the extracranial vertebral artery, its radicular or muscular branches, and adjacent venous structures.

Case Presentation: We report an asymptomatic patient of fistula from the vertebral artery to the paravertebral veins secondary to a cervical stab wound that increased in size and flow, as observed on the angiogram 10 days later, which was successfully treated by endovascular surgery.

Migration of lipiodol into lateral ventricles after embolization of cerebral arteriovenous malformation: a case report.

N-butyl cyanoacrylate (NBCA) has been used to embolise brain arteriovenous malformations (AVMs) for over 30 years. It is a mixed with lipiodol in varying proportions. We report a 22-year-old male with intraventricular hemorrhage from a ruptured intranidal AVM aneurysm in the left temporal lobe.
