INTRODUCTION The Apollo system (Penumbra Inc, Alameda, California, USA) is a low profile irrigation-aspiration system designed for the evacuation of intracranial hemorrhage. OBJECTIVE To demonstrate the feasibility of using Apollo in combination with cone beam CT guidance. METHODS Parenchymal (n=1) and mixed parenchymal-intraventricular hematomas (n=1) were created in cadaver heads using a ...

Electrophysiology procedures are in many cases performed under fluoroscopic guidance. As the heart is not visible under fluoroscopy, a preoperatively acquired heart model of the patient may be fused with the live X-ray images to provide the physician with a better orientation. This heart model needs to be registered to the fluoroscopic images. Currently, registration is performed manually, e.g....

Ten percutaneous transnasal sphenoidotomies were performed in nine children; and in seven, a sphenoid window was also created. All procedures were performed in the special procedures laboratory, with biplane fluoroscopic guidance used in each case. Under general anesthesia, with the child in the supine position, a 14-gauge antral trocar was placed transnasally into the sphenoid sinus. The sinus...

Transcatheter aortic valve implantation (TAVI) is routinely performed under 2D fluoroscopic guidance. The target position for placement of the stented aortic valve prosthesis is defined by aortic valve landmarks, e.g. coronary ostia. This paper presents a real-time tracking method of these landmarks in 2D fluoroscopic image sequences to improve the positioning of the implant during TAVI. The pr...

INTRODUCTION Our report presents a technique of necrotic tissue removal during transmural drainage of walled-off pancreatic necrosis (WOPN) that is an alternative to the one that has already been described in the literature. AIM To assess the effectiveness and safety of endoscopic necrosectomy performed during transmural drainage of symptomatic WOPN. MATERIAL AND METHODS Within the years 20...
