medical applications of synchrotron radiation
Physics in Medicine and Biology, 2003Co-Authors: P Suortti, W ThomlinsonAbstract:The medical imaging and therapeutic technologies that are based on the use of radiation are reviewed briefly, with special emphasis on the recent developments of synchrotron radiation (SR) methods. New results have been achieved in all of these areas since the last comprehensive reviews were written in this field. This topical review is intended to make the latest possible results and complete set of references available. The different contrast mechanisms in imaging by x-rays are described. The applications range from whole-body imaging to studies of atomic and molecular structures. The SR imaging applications include coronary angiography, Bronchography, mammography, computed tomography, x-ray microscopy and imaging by scattering. The therapy applications include photon activation therapy and microbeam radiation therapy.

endobronchial closure of bronchopleural fistulas with amplatzer vascular plug
European Journal of Cardio-Thoracic Surgery, 2011Co-Authors: Oren Fruchter, Elchanan Bruckheimer, Yael Raviv, Dror Rosengarten, Milton Saute, Mordechai R KramerAbstract:OBJECTIVE: Bronchopulmonary fistula (BPF) is a severe complication following lobectomy or pneumonectomy and is associated with a high rate of morbidity and mortality. We have developed a novel minimally invasive method of central BPF closure using Amplatzer vascular plug (AVP) device that was originally designed for the transcatheter closure of vascular structures in patients with small BPF. METHODS: Patients with BPFs were treated under conscious sedation by bronchoscopic closure of BPFs using AVP. After locating the fistula using Bronchography, the self-expanding nitinol made AVP occluder to be delivered under direct bronchoscopic guidance over a loader wire into the fistula followed by Bronchography to assure correct device positioning and sealing of the BPF. RESULTS: Six AVPs were placed in five patients, four males and one female, with a mean age of 62.3 years (range: 51–82 years). The underlying disorders and etiologies for BPF development were lobectomy (two patients), pneumonectomy for lung cancer (one patient), lobectomy due to necrotizing pneumonia (one patient), and post-tracheostomy tracheo-pleural fistula (one patient). In all the patients, the bronchoscopic procedure was successful and symptoms related to BPF disappeared following closure by the AVP. The results were maintained over a median follow-up of 9 months (range: 5–34 months). CONCLUSIONS: Endobronchial closure using the AVP is a safe and effective method for treatment of small postoperative BPF. The ease of their implantation by bronchoscopy under conscious sedation adds this novel technique to the armatorium of minimally invasive modalities for the treatment of small BPF.

the histological response of the lungs of rats to potentially suitable water soluble bronchographic contrast agents iotrolan a non ionic dimer and iopamidol a non ionic monomer
British Journal of Radiology, 1993Co-Authors: A Z Ginai, A Bubberman, P E Zondervan, W. Van Leeuwen, Sameh K MorcosAbstract:Abstract The recent need for selective Bronchography during bronchoscopy in certain patients, together with paediatric indications for tracheo-Bronchography, raises the question as to which contrast medium is both safe and efficient. The purpose of the present experimental study was to define the tissue reaction caused by iotrolan and iopamidol in the bronchi and lungs of rats. 60 animals used in this study were divided into five groups receiving iotrolan 300, iopamidol 370, iopamidol 150, physiological saline and anaesthetic only, the last two acting as control groups. Statistically there was no significant difference in the histological reaction between iotrolan 300, iopamidol 370 and iopamidol 150 compared with the control groups, although iotrolan 300 appeared to result in the least tissue reaction. With its adequately high iodine concentration, low osmolality and relatively high viscosity, iotrolan 300 would appear to be a suitable contrast medium for Bronchography.

endobronchial closure of total bronchopleural fistula with occlutech figulla asd n device
The Annals of Thoracic Surgery, 2009Co-Authors: Miguel Lia Tedde, Paulo Rogerio Scordamaglio, Helio Minamoto, Viviane Rossi Figueiredo, Carlos C Pedra, Fabio Biscegli JateneAbstract:Bronchopleural fistula may be treated by medical, endoscopic, and surgical techniques, but large fistulas remain a challenge to be closed using endoscopic techniques. We describe the endoscopic closure of a bronchial total fistula with the Occlutech Figulla ASD N device (International Occlutech AB, Helsingborg, Sweden), originally designed for closure of an atrial septal defect. The procedure was conducted without general anesthesia or rigid bronchoscopy, Bronchography, or radioscopy. An immediate reduction in the air leak was observed and also later on bronchoscopy, as the device was almost covered by granulation tissue. The endobronchial technique described seems to be safe and effective to manage large bronchopleural fistulas.
