A Keyhole Approach for Intracranial Hematoma Removal Using ORBEYE.

Objective: By maximizing the advantages of exoscopy, we developed a keyhole approach for intracranial hematoma removal. Herein, we validated the utility of this procedure, and compared it with conventional microscopic hematoma removal and endoscopic hematoma removal in our institution.

Methods: We included 12 consecutive patients who underwent this procedure from June 2022 to March 2024.

A Case of Pontine Infarction due to Subclavian Steal Phenomenon Enhanced by an Arteriovenous Shunt for Hemodialysis.

We present a case of pontine infarction caused by subclavian steal phenomenon (SSP) due to subclavian artery stenosis (SAS) and an arteriovenous shunt in the forearm in a 74-year-old man with hemodialysis and stenting for SAS with improvement of SSP. He developed dysarthria during dialysis. He was admitted to our hospital and diagnosed with a pontine infarction.

Lumbar Lordosis is a Risk Factor for Lumbar Catheter Fracture of Lumboperitoneal Shunt.

Objective: This study aimed to investigate the causes of lumboperitoneal (LP) shunt failure and determine risk factors for lumbar catheter fracture.

Methods: We retrospectively investigated 149 patients who underwent LP shunting in our hospital between January 2012 and March 2023. Shunt reconstruction occurred in 22 patients (14.

Statistical Analysis of the Factors that Affect Postoperative Length of Hospital Stay after Unruptured Intracranial Aneurysm Treatment in Japan: A 20-year Nationwide Multicenter Study.

Treatment strategies for unruptured intracranial aneurysms (UIAs) should be carefully considered with reference to rupture and complication rates. It is also important to minimize the length of hospital stay (LOS) and to ensure a high quality of medical care. In this study, we aim to clarify the factors that affect the LOS of patients treated for UIAs using the Inpatient Clinico-Occupational Database of the Rosai Hospital Group (ICOD-R).

The Usefulness of Surgical Titanium Microclips for Mucosal Repair in the Frontal Sinus Using ORBEYE: A Technical Note.

Bifrontal craniotomy frequently involves opening the frontal sinus and mucosal injury. We report a new technique for mucosal repair in the frontal sinus using surgical titanium microclips. Six consecutive patients who underwent bifrontal craniotomy with frontal sinus exposure and mucosal injury underwent mucosal repair using surgical titanium microclips between April 2019 and August 2022.

Cerebral Venous Sinus Thrombosis Successfully Treated with Mechanical Thrombectomy under Intracranial Pressure Monitoring: A Case Report.

A 54-year-old man with no medical history presented to our hospital with vomiting, left hemiplegia, and seizures. On arrival, he was experiencing generalized tonic-clonic seizures, which required him to be intubated and deeply sedated. Contrast-enhanced computed tomography revealed extensive venous sinus obstruction from the superior sagittal sinus to the bilateral sigmoid sinus and cerebral edema with intracranial hemorrhage.

Long-term Patency of Retrograde Bypass Using a Distal Stump of the Parietal Superficial Temporal Artery for Moyamoya Disease.

There have been a number of anastomosis methods of bypass techniques reported for moyamoya disease. However, there are yet no randomized controlled trials conducted on the anastomosis method. Retrograde blood flow of the superficial temporal artery (STA) may be used as one of the donor options.

Overlapped Double-Layer Micromesh Stents for Giant Extracranial Internal Carotid Artery Aneurysm.

Objective: Extracranial internal carotid artery aneurysms (ECAAs) are rare. We herein describe a case of overlapped stenting with two double-layer micromesh stents for a giant ECAA.

Case Presentation: A 73-year-old man presented to our hospital with an enlarged right posterior cervical mass.

Tension Pneumocephalus Following LP Shunt due to Congenital Bone Defects: A Case Report.

A 72-year-old man who had undergone a lumboperitoneal shunt for idiopathic normal pressure hydrocephalus was admitted to our emergency department with fever and disturbance of consciousness 8 days after placement. Computed tomography scan showed pneumocephalus and a right-sided temporal porencephalic cyst with a small bone defect in the right petrous bone. Shunt valve pressure was raised from 145 mmHO to "virtual off" setting.
