Comparison of treatment results between microvascular decompression and gamma knife radiosurgery in primary trigeminal neuralgia.

This study aims to analyze and evaluate the comparative clinical outcomes associated with microvascular decompression (MVD) and gamma knife radiosurgery (GKRS), focusing on pain relief, pain recurrence, and complications encountered in the treatment of trigeminal neuralgia (TN). Among 155 surgical procedures performed for TN (90 GKRS, and 65 MVD) between March 1997 and December 2020, the exclusion criteria encompassed prior surgical interventions, the presence of other pathological conditions such as tumors, vascular diseases, and multiple sclerosis, as well as patients who were lost to follow-up. Ultimately, 101 patients received their initial treatment for primary TN (47 GKRS, and 54 MVD) and were followed up for more than 1 year.

Methods: We retrospectively reviewed the records of 70 patients with an unruptured A-com aneurysm treated with coiling or clipping performed by a hybrid vascular neurosurgeon between March 2012 and December 2019. The patients were dichotomized, into the coil group or clip group.

Endovascular treatment of the vertebral artery origin stenosis by using the closed-cell, self-expandable Carotid Wallstent.

Background: Endovascular treatment has been considered a good alternative to surgery for symptomatic vertebral artery origin stenosis (VAOS) due to the high risk of morbidity associated with surgery. The purpose of this study was to evaluate the feasibility and efficacy of insertion of the closed-cell, self-expandable Carotid Wallstent for the treatment of VAOS.

Methods: The records of 72 patients with VAOS refractory to adequate medication who were treated by endovascular treatment with the Carotid Wallstent from December 2006 to November 2018 were retrospectively evaluated.

Does Systemic Lupus Erythematosus Increase the Risk of Procedure-Related Complication in Endovascular Treatment of Intracranial Aneurysm?

Cerebral aneurysms associated with systemic lupus erythematosus (SLE) are more likely to grow rapidly and rupture, compared to those found in the general population. The main underlying pathology of intracranial aneurysm and its rupture is presumed to be SLE-related intracranial vasculitis and fragility of blood vessels due to prolonged use of steroid. For these reasons, both surgical and endovascular options are challenging.

Endovascular treatment of ruptured tiny aneurysms.

Objective: Endovascular coiling of ruptured tiny aneurysms (RTAs) in the brain has been known to be technically challenging owing to the higher rate of adverse events, such as thromboembolism and intraoperative rupture. The aim of this study was to report our ex-periences of endovascular treatment of RTAs (size, ≤3 mm).

Methods: From January 2006 to December 2017, 35 RTAs in 35 patients were treated at our institution with an endosaccular coiling.

Obtaining Informed Consent Using Patient Specific 3D Printing Cerebral Aneurysm Model.

Objective: Recently, three-dimensional (3D) printed models of the intracranial vascular have served as useful tools in simulation and training for cerebral aneurysm clipping surgery. Precise and realistic 3D printed aneurysm models may improve patients' understanding of the 3D cerebral aneurysm structure. Therefore, we created patient-specific 3D printed aneurysm models as an educational and clinical tool for patients undergoing aneurysm clipping surgery.

Objective: So far, there is no study answering the question of which type of surgical technique is practically the most useful in the treatment of adult patients with ischemic type moyamoya disease (MMD). We evaluated the efficacy of single barrel superficial temporal artery (STA)-middle cerebral artery (MCA) bypass in the treatment of adult patients with ischemic type MMD by retrospectively collecting clinical and radiological data.

Materials And Methods: A retrospective review identified 31 adult patients who underwent 43 single barrel STA-MCA bypass procedures performed for treatment of ischemic-type MMD between 2006 and 2014.

Extracranial vertebral artery rupture likely secondary to "cupping therapy" superimposed on spontaneous dissection.

The extracranial vertebral artery (VA) is vulnerable to dissection and the V3 segment is the most common location for dissection. Dissection accounts for about 2% of all ischemic strokes and can occur after trauma or chiropractic neck maneuvers. We report an extremely rare case of spontaneous extracranial VA dissection presenting with posterior neck hematoma aggravated after cupping therapy, a treatment in traditional Oriental medicine.
