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

Abstract:
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

Object. The aim of this study was to evaluate the causes of treatment failure in patients with arteriovenous malformations (AVMs) who underwent radiosurgery, which is increasingly used as a treatment method for selected, surgically high-risk AVMs. Unfortunately, radiosurgical treatment fails in a small but significant percentage of patients. In the time period covered in this study, 72 patients attained angiographically confirmed cures after radiosurgery and 36 were retreated after the initial radiosurgical treatment failed. Methods. Using a computerized image fusion technique, the initial rad

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

Abstract:
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. Equations for skull radii are derived by approximating the skull as an ellipsoid. No proprietary software other than that

Abstract:
Object The authors reviewed the radiosurgical outcomes in patients with arteriovenous malformations (AVMs) located in the rolandic area, including the primary motor and sensory gyri. Methods The study population consisted of 38 patients with rolandic-area AVMs who underwent linear accelerator radiosurgery at the University of Toronto between 1989 and 2000. Obliteration rate, risk of hemorrhage during the latency period, radiation-induced complications, seizure control, and functional status were evaluated. Patients were also divided into two subgroups according to AVM volume (< 3 cm3 and ≥

Abstract:
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:
Brain metastases occur in 20–40% of cancer patients. The main methods of treatment are neurosurgical intervention, radiation therapy, and stereotactic radiosurgery is actively developing. The advantage of radiosurgery is non-invasiveness, the effectiveness of exposure to foci and the low probability of radiation reactions after treatment. However, in patients with a tumor volume exceeding 3 centimeters in diameter, with radiosurgical doses (>18 Gy), the risk of post-radiation complications is subsequently high, therefore radiosurgical methods of hypofractionation and staged radiosurgery are
