The objective of this study is to preliminarily evaluate a lesion-targeting device for CT-guided interventions. The device is created by laser cutting the structure from a sheet of medical grade paperboard, 3D printing two radiocontrast agent grids onto the surface and folding the structure into a rectangular prism with a viewing window. An abdominal imaging phantom was used to evaluate the device through CT imaging and the targeting of lesions for needle insertion. The lesion-targeting trials resulted in a mean targeting error of 2.53 mm (SD 0.59 mm, n = 30). The device is rigid enough to adequately support standard biopsy needles, and it attaches to the patient, reducing the risk of tissue laceration by needles held rigidly in place by an external manipulator. Additional advantages include adequate support for the insertion of multiple surgical tools at once for procedures such as composite ablation and the potential to guide off-axial needle insertion. The low-cost and disposability of the device make it well-suited for the minimally invasive image-guided therapy environment.

Stereotactic Biopsies

153 cases of CT guided stereotactic biopsies for intra-axial deep seated brain lesions performed by one neurosurgeon has been analyzed regarding procedure, success rate and complications. Of the 153 cases, positive tissue biopsy was found in 143 cases. In 6 patients, biopsy showed gliotic grain tissue or normal brain tissue.4 patients had complications after the procedure. Three patient developed intracerebral haemorrhage of the two died, and other died Massive MI. There was no post operative new deficits seen. CT guided Stereotactic biopsy is a very effective and low cost procedure caomparing with frameless image guided brain biopsies or open craniotomy for biopsy due to it’s higher complication rate. The detail procedure are being discussed Bang. J Neurosurgery 2020; 9(2): 86-93

AbstractVascular endoscopic imaging is known for a long time but has never made its way into clinical routine. Reasons for that are the complexity, lack of low-cost portable systems, and the lack of suitable endoscopes providing high image quality with small dimensions. In addition, an interruption of the blood flow caused by the device and the opacity of blood are difficult to manage. In the past we have already developed ideas to overcome these difficulties and now we present a feasibility test of a thin diameter ureteroscope for observation of vascular procedures. The imaging system was tested in a phantom where side branches were explored, a stent was placed and a simulated aneurysm coiled.

The authors describe a simple and low-cost technique for image-guided cannulation of the foramen ovale during treatment of medically refractory trigeminal neuralgia using percutaneous radiofrequency rhizotomy. Computed tomography-guided neuronavigation and the noninvasive ear, nose, and throat Small Active Frame system were applied for visualization of cannulation of the foramen ovale in the awake patient. Use of invasive head-clamp fixation was unnecessary. Three patients were treated using this technique in which the foramen ovale was reached using a single tract. No adverse effects of this technique were reported. The potential benefits and disadvantages of this method are presented.
