Abstract:

Introduction. Aﬅer the loss of kidney transplant function, patient curation can be a diﬃcult task. Nephrotransplantectomy (NTE) is the method of choice between reduction of immunosuppression with the abandonment of a non-functioning kidney transplant and embolization. This is an operation with potentially signiﬁcant indicators of blood loss, complications and mortality. Along with traditional NTE, we began to use endovascular isolation of the allograﬅ as a method of preoperative preparation before its removal.The aim of the work is to investigate the eﬀect of the use of radiosurgical minimally

The purpose of the study was the effective assessment and safety of the lacrimal ducts obturation by using radio wave energy in patient with “dry eye” syndrome with sagnificant damage of the ocular surface. Materials and methods. A retrospective analysis of data as patients radiosurgical blocking of tear flow was performed was carried out. Occlusion of the lacrimal ducts was carried out according to the own method using “Surgitron™” devices. The radio wave low-temperature event leads to persistent closure of the lumen of the lacrimal ducts and blockage of the passage of the lacrimal fluid. Res

Abstract:

Abstract BACKGROUND Radiosurgical treatment of high-grade gliomas usually bases target definition on contrast-enhanced T1-weighted MRI images. Despite advances in several MRI techniques, a number of limitations exist, primarily due to the disruption of the blood-brain barrier, making the target delineation less accurate, particularly when treating recurrences. Several studies support the use of amino acid PET/MRI in distinguishing progression from post-operative/post-radiation inflammation. However, no established guidelines define the biological target volume when using amino acid PET/MRI in

Object Gamma Knife (GK) treatments are typically delivered in 1 day with little opportunity to test different planning strategies. The authors demonstrate 2 methods for imposing GK coordinate systems upon imaging datasets without frame attachment to allow leisurely preprocedural planning, and discuss potential applications. Methods A “virtual framing” is constructed by coregistering a CT scan of a Leksell frame with a patient dataset using the GammaPlan (Multiview) module.

Object. Radiosurgical treatment of a cerebral arteriovenous malformation (AVM) requires the precise definition of the nidus of the lesion in stereotactic space. This cannot be accomplished using simple stereotactic angiography, but requires a combination of stereotactic biplanar angiographic images and stereotactic contrast-enhanced computerized tomography (CT) scans. In the present study the authors describe a method in which three-dimensional (3D) rotational angiography is integrated into stereotactic space to aid treatment planning for radiosurgery. Methods.

Abstract BACKGROUND High-definition vascular imaging is desirable for treatment planning in Gamma Knife radiosurgery (GKRS; Elekta AB) for brain arteriovenous malformations (BAVMs). Currently, rotational angiography (RA) provides the clearest 3-dimensional visualization of niduses with high spatial resolution; however, its efficacy for GKRS has not been clarified. At our institution, RA has been integrated into GKRS (RA-GKRS) for better treatment planning and outcomes since 2015.

✓ A conformity index is a measure of how well the volume of a radiosurgical dose distribution conforms to the size and shape of a target volume. Because the success of radiosurgery is related to the extremely conformal irradiation of the target, an accurate method for describing this parameter is important. Existing conformity ratios and indices used in radiosurgery are reviewed and criticized. It will be demonstrated that previously proposed measurements of conformity can, under certain conditions, give false perfect scores.

Ruptured cerebral arteriovenous malformations (AVMs) usually require treatment to avoid re-bleeding. Depending on the angioarchitecture and center strategy, the treatment can be surgical, endovascular, radiosurgical or combined methods. The classic endovascular approach is transarterial, but sometimes it is not always applicable. The transvenous approach has been described as an alternative for the endovascular treatment of small AVMs when arterial access or another therapeutic method is not possible. This approach can be considered when the nidus is small and if there is a single draining vei

Abstract Purpose To investigate the clinical value of the inflammation based prognostic scores for patients with radiosurgically treated brain metastases (BM) originating from non-pulmonary primary tumor (PT). Methods A retrospective analysis of 340 BM patients of different PT origin (melanoma, breast, gastrointestinal, or genitourinary cancer) was performed. Pre-radiosurgical laboratory prognostic scores, such as the Neutrophil-to-Lymphocyte Ratio (NLR), the Platelet-to-Lymphocyte Ratio (PLR), Lymphocyte-to-Monocyte Ratio (LMR), and the modified Glasgow Prognostic Score (mGPS), were investiga

Abstract:

Radiosurgery is the utmost form of targeted radiation treatment that can eradicate the gross tumors, and it is a non-invasive procedure. It requires a high degree of accuracy and precision in targeting the deep-seated tumors which are usually surrounded by the functionally important normal structures. Recent advances of immobilization method and computerizedradiation delivery method with intensity modulation made it possible to perform radiosurgery to the spine. Spine radiosurgery achieved a rapid and durable pain control in majority of patients with spine metastasis. Radiosurgical decompressi

Abstract:

Essential tremor and Parkinson's disease–associated tremor are extremely prevalent within the field of movement disorders. The ventral intermediate (VIM) nucleus of the thalamus has been commonly used as both a neuromodulatory and neuroablative target for the treatment of these forms of tremor. With both deep brain stimulation and Gamma Knife radiosurgery, there is an abundance of literature regarding the surgical planning, targeting, and outcomes of these methodologies. To date, there have been no reports of frameless, linear accelerator (LINAC)–based thalomotomies for tremor.The authors repo

Radiosurgical treatment of trigeminal neuralgia has been well investigated with gamma knife devices involving fixed cobalt sources. Few reports exist concerning trigeminal neuralgia treated using linear accelerator (LINAC)—based devices. In recent years these devices have reached the level of mechanical precision that is required for such functional treatments. The authors describe their initial experience with radiosurgi

In contrast to conventional microsurgery, stereotactic radiosurgery has an advantage in the treatment of intracranial masses, avoiding severe complications associated with open surgery. In rare cases, the use of the method is associated with the development of radiation-induced injuries, one of which is radiation necrosis (RN). This is a late complication of radiosurgery, developing mainly 6 months after radiation exposure. The neurological manifestations of this complication depend on location, and the clinical picture is very diverse. The method of magnetic resonance imaging (MRI) with intra
