Holmium-166 labeled DTPA Bisamide Derivatives for Radiation Brachytherapy using Balloon Catheters
Coronary angioplasty is performed by inserting a percutaneous transluminal coronary angioplasty (PTCA) balloon catheter into a stenosed coronary artery. The opening process is achieved by a simple repeated inflation of the balloon, which applies pressure to the artery walls. However, a re-closure rate of 50% results from this treatment. The radioactive liquid balloon is proposed as one of the m...
متن کاملEffects of Intraluminal Irradiation with Holmium-166 for TIPS Stenosis: Experimental Study in a Swine Model
OBJECTIVE We wanted to evaluate the effectiveness of intraluminal irradiation with Holmium-166 ((166)Ho) for reducing the pseudointimal hyperplasia (PIH) in the transjugular intrahepatic portosystemic shunt (TIPS) tract in a swine model. MATERIALS AND METHODS TIPS was performed in 12 domestic pigs, after the creation of portal hypertension by intraportal injection of a mixture of N-butyl-2-cy...
متن کاملIntracavitary Radiation Therapy for Recurrent Cystic Brain Tumors with Holmium-166-Chico : A Pilot Study
OBJECTIVE Intracavitary injection of beta-emitting radiation source for control of cystic tumors has been tried with a benefit of localized internal radiation. The authors treated cystic brain tumor patients with Holmium-166-chitosan complex (Ho-166-chico), composed of a beta-emitting radionuclide Holmium-166 and biodegradable chit polymer, and evaluated the safety and effective measurement for...
متن کاملIntraoperative Balloon Angioplasty Using Fogarty Artertial Embolectomy Balloon Catheter for Creation of Arteriovenous Fistula for Hemodialysis: Single Center Experience
BACKGROUND The purpose of this study was to evaluate the use of a Fogarty arterial embolectomy catheter (Fogarty catheter) in intraoperative balloon angioplasty of the cephalic vein, in order to determine its effect on the patency of arteriovenous fistulas (AVFs) created for hemodialysis access. METHODS A total of 156 patients who underwent creation of an AVF were divided into two groups, bas...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
