Deep Learning Detection and Segmentation of Brain Arteriovenous Malformation on Magnetic Resonance Angiography.

Background: The delineation of brain arteriovenous malformations (bAVMs) is crucial for subsequent treatment planning. Manual segmentation is time-consuming and labor-intensive. Applying deep learning to automatically detect and segment bAVM might help to improve clinical practice efficiency.

Influence of the Timing of Leptomeningeal Metastasis on the Outcome of -Mutant Lung Adenocarcinoma Patients and Predictors of Detectable Mutations in Cerebrospinal Fluid.

Background: We aim to evaluate the influence of the timing of leptomeningeal metastasis (LM) occurrence on the outcome of -mutant lung adenocarcinoma and to explore the predictors of detectable mutation in the cerebrospinal fluid (CSF).

Methods: -mutant lung adenocarcinoma patients with cytologically confirmed LM were included for analysis. mutation in CSF was detected by MALDI-TOF MS plus PNA.

Outcome of intracerebral cavernoma treated by Gamma Knife radiosurgery based on a double-blind assessment of treatment indication.

Background: The benefit and the risk profile of Gamma Knife radiosurgery (GKRS) for intracerebral cavernoma remains incompletely defined in part due to the natural history of low incidence of bleeding and spontaneous regression of this vascular malformation. In this study, we retrieved cases from a prospectively collected database to assess the outcome of intracerebral cavernoma treated with GKRS using a double blinded review process for treatment.

Methods: From 2003 to 2018, there were 94 cases of cavernoma treated by GKRS in the doubly blinded assessments by two experienced neurological and approved for GKRS treatment.

Outcome of partially irradiated recurrent nonfunctioning pituitary macroadenoma by gamma knife radiosurgery.

Background: Gamma knife treatment outcome of large pituitary tumors which are only partially irradiated secondary to immediate proximity to critical structures such as the optic apparatus have not been rigorously studied.

Materials And Methods: From July 2003 to December 2013, there were 41 cases of recurrent or residual nonfunctioning pituitary macroadenoma partially treated with gamma knife radiosurgery (GKRS) because the adenoma obscured part of the optic apparatus on planning SRS MR imaging.

Results: The follow up period after GKRS was 92.

Outcome of hearing preservation related to tumor morphologic analysis in acoustic neuromas treated by gamma knife radiosurgery.

Background: Gamma Knife radiosurgery (GKRS) is an important part of the neurosurgical armamentarium in the treatment of acoustic neuromas. However, the treatment outcome related to the morphology of the tumor has not been rigorously studied. In this cohort, we evaluated the morphological features of the tumor in the tumor response and neurological outcomes after GKRS.

Temporary clamping of bilateral external carotid arteries for surgical excision of a complex dural arteriovenous fistula.

Background: Some complex dural arteriovenous fistulas (DAVFs) are lesions that typically have numerous arterial feeders. Surgery, including resection of fistulas or skeletonization of the diseased sinus, is still one of the important treatments for these lesions. However, major blood loss is usually encountered during craniotomy because of abundant arterial feeders from the scalp and transosseous vessels.

Stereotactic biopsy for brainstem lesion: comparison of approaches and reports of 10 cases.

Background: Stereotactic biopsy for brainstem lesion offers high diagnostic yield with low morbidity. We compared two modalities of biopsy procedure, frame-based and frameless stereotaxy, either transfrontal or transcerebellar route. The benefits and operation considerations are discussed.

Radiosurgery for dural carotid-cavernous sinus fistulas: Gamma Knife compared with XKnife radiosurgery.

Object: In the modern era, stereotactic radiosurgery is an important part of the multidisciplinary and multimodality approach used to treat dural carotid-cavernous fistulas (DCCFs). Based on the ease of performance of techniques to fuse cerebral angiography studies with MR images or CT scans during the radiosurgical procedure, the Gamma Knife and XKnife are 2 of the most popular radiosurgical instruments for patients with DCCF. In this study, the authors compared the efficacy, neurological results, and complications associated with these 2 radiosurgical devices when used for DCCF.

Aspiration of hypertensive intracerebral hematoma with frameless and fiducial-free navigation system: technical note and preliminary result.

Unlabelled: Stereotactic aspiration of hematoma is an effective method for the treatment of basal ganglia hematoma. Hematoma aspiration with a frameless navigation system using external fiducials has been published in the literature. But the literature is lacking in the use of a fiducial-free method for frameless aspiration of hematoma.

Histopathology of radiation necrosis with severe peritumoral edema after gamma knife radiosurgery for parasagittal meningioma. A report of two cases.

Background: Gamma knife radiosurgery (GKS) has been an effective treatment for meningiomas. Nevertheless, it still has certain risks. We present 2 cases of parasagittal meningioma after GKS complicated with radiation necrosis and peritumoral edema.

Prediction of volumetric data errors in patients treated with gamma knife radiosurgery.

Purpose: Volumetry is the most commonly used method to measure tumor response in patients who receive Gamma Knife radiosurgery. We calculated the data errors in measurement made by different methods based on the stereotactic fiducials (Gamma Knife workstation), surface area multiplied by thickness (PACS), and product of maximum diameter in x, y, and z dimensions (geometric method) to more precisely evaluate tumor response in patients treated with Gamma Knife radiosurgery.

Materials And Methods: From 2003 to 2006, 210 tumors were enrolled in this study.

Multidisciplinary treatment of cavernous sinus dural arteriovenous fistulae with radiosurgery and embolization.

Objective: With the advent of interventional neuroradiology and stereotactic radiosurgery, dural arteriovenous fistulae are less often managed with open surgery. We evaluated the outcome of dural arteriovenous fistulae of the cavernous sinus treated with a combination of radiosurgery and embolization.

Material And Methods: Twenty dural arteriovenous fistulae located in the cavernous sinus were enrolled in our study.

Upper thoracic sympathectomy for axillary osmidrosis or bromidrosis.

The difference between axillary osmidrosis (AO) and axillary bromidrosis (AB) is the degree of odor and quantity of sweat, which is associated with selection of therapeutic modality theoretically. Upper thoracic sympathectomy has been used for both diseases but its effect needs to be further evaluated with more clinical data. We collected 108 patients with AO or AB treated by upper thoracic sympathectomy from July 1995 to July 2002.

Radiosurgery in patients with renal cell carcinoma metastasis to the brain: long-term outcomes and prognostic factors influencing survival and local tumor control.

Object: Renal cell carcinoma is a leading cause of death from cancer and its incidence is increasing. In many patients with renal cell cancer, metastasis to the brain develops at some time during the course of the disease. Corticosteroid therapy, radiotherapy, and resection have been the mainstays of treatment.

Radiosurgery for non-small cell lung carcinoma metastatic to the brain: long-term outcomes and prognostic factors influencing patient survival time and local tumor control.

Object: Lung carcinoma is the leading cause of death from cancer. More than 25% of those patients with lung cancer develop a brain metastasis at some time during the course of their disease. Corticosteroid therapy, radiotherapy, and resection have been the mainstays of treatment.

Anatomical location of T2-3 sympathetic trunk and Kuntz nerve determined by transthoracic endoscopy.

Object: Bilateral subaxillary transthoracic endoscopic sympathectomy (TES) is a popular procedure of upper thoracic sympathectomy. The anatomical locations of the T-2 and T-3 sympathetic trunks, as viewed under the endoscope, are varied in the rib head areas. In this study, the authors investigated the more visible anatomical locations of the T-2 and T-3 sympathetic trunks, the so-called nerves of Kuntz, and intercostal rami by performing transthoracic endoscopy.
