long term results of primary avulsion of posterior urethral valves using a fogarty Balloon Catheter
The Journal of Urology, 2002Co-Authors: Boris Chertin, Denis A Cozzi, Prem PuriAbstract:ABSTRACTPurpose: Posterior urethral valves are the most common cause of bladder outlet obstruction in infancy and cause renal failure in 25% to 30% of these children before adolescence. Transurethral ablation under direct vision is the most commonly used method of treatment for posterior urethral valves. Since 1987 we have used a Fogarty Balloon Catheter for primary avulsion of the posterior urethral valves in our patients. We evaluate the long-term results of this technique.Materials and Methods: During 14 years (1987 to 2001) 35 consecutive patients with posterior urethral valves underwent primary valve avulsion using a Fogarty Balloon Catheter. In 21 patients diagnosis was made prenatally, while the remaining 14 patients (6 newborns and 8 children with median age of 6 months) presented with urinary tract infection and renal failure. Vesicoureteral reflux was present in 22 (63%) of the 35 patients involving 34 renal units. Primary valve avulsion was performed using a 4Fr Fogarty Balloon Catheter under f...

Dual-Lumen Balloon Catheter Technique for Onyx Embolization of Spinal Dural Arteriovenous Fistula.
Journal of vascular and interventional neurology, 2019Co-Authors: Muhammet Arslan, Celal Cinar, Ismail OranAbstract:Spinal dural arteriovenous fistula (SDAVF) is the most common type of spinal vascular malformation. The main purpose of endovascular treatment is to occlude the fistula site and the proximal part of the draining vein. However, this is not always possible because of the difficulty of selective Catheterization in patients with tortuous feeding arteries, as well as the risk of reflux of the liquid embolic agent. Herein, we present three cases in which a dual-lumen Balloon Catheter together with a liquid embolic agent was used to occlude the SDAVF. Complete and persistent occlusion was confirmed by magnetic resonance images taken at 6 months after the treatment. Using the dual-lumen Balloon Catheter technique in cases of long and tortuous feeder arteries supplying the SDAVF can result in safe and successful embolization.

onyx embolization for isolated type dural arteriovenous fistula using a dual lumen Balloon Catheter
Neurosurgery, 2016Co-Authors: Jin Woo Kim, Byung Moon Kim, Keun Young Park, Dong Joon Kim, Dong Ik KimAbstract:BACKGROUND Utilization of a dual-lumen Balloon may improve Onyx penetration into isolated dural arteriovenous fistulas (i-DAVFs). OBJECTIVE To compare the results of Onyx embolization using a dual-lumen Balloon with those using a non-Balloon Catheter for i-DAVFs. METHODS Twenty-nine patients underwent Onyx embolization for i-DAVFs using a non-Balloon (n = 14) or a dual-lumen Balloon Catheter (n = 15). Since its introduction, a dual-lumen Balloon Catheter has been preferred. We compared the dual-lumen Balloon group with the non-Balloon Catheter group regarding angiographic outcome, treatment-related complications, total procedural time, Onyx injection time, and the number of feeders requiring embolization. RESULTS The dual-lumen Balloon group showed complete occlusion of i-DAVFs in 13 and near-complete in 2 patients, while the non-Balloon group showed complete occlusion in 5, near-complete in 5, and incomplete in 4 patients (P < .05). Treatment-related complications occurred in 2 patients: 1 in the non-Balloon group and 1 in the dual-lumen Balloon group. The mean total procedural time was 62 ± 32 minutes in the dual-lumen Balloon and 171 ± 88 minutes in the non-Balloon group (P < .05). The mean Onyx injection time was 10 ± 6 minutes in the dual-lumen Balloon and 49 ± 32 minutes in the non-Balloon group (P < .05). The median number of feeders requiring embolization was 1 (range, 1-3) in the dual-lumen Balloon and 2 (range, 1-4) in the non-Balloon group (P < .05). CONCLUSION Utilization of a dual-lumen Balloon Catheter for Onyx embolization of i-DAVF seemed to significantly increase the immediate complete occlusion rate and decrease total procedural time, Onyx injection time, and number of feeders requiring embolization.

endoscopic endonasal control of the paraclival internal carotid artery by fogarty Balloon Catheter inflation an anatomical study
Journal of Neurosurgery, 2017Co-Authors: Andrea Ruggeri, Joaquim Ensenat, Alberto Pratsgalino, Antonio Lopezrueda, Joan Berenguer, Martina Cappelletti, Matteo De Notaris, Elena DavellaAbstract:OBJECTIVE Neurosurgical management of many vascular and neoplastic lesions necessitates control of the internal carotid artery (ICA). The aim of this study was to investigate the feasibility of achieving control of the ICA through the endoscopic endonasal approach by temporary occlusion with a Fogarty Balloon Catheter. METHODS Ten endoscopic endonasal paraseptal approaches were performed on cadaveric specimens. A Fogarty Balloon Catheter was inserted through a sellar bony opening and pushed laterally and posteriorly extraarterially along the paraclival carotid artery. The Balloon was then inflated, thus achieving temporary occlusion of the vessel. The position of the Catheter was confirmed with CT scans, and occlusion of the ICA was demonstrated with angiography. The technique was performed in 2 surgical cases of pituitary macroadenoma with cavernous sinus invasion. RESULTS Positioning the Fogarty Balloon Catheter at the level of the paraclival ICA was achieved in all cadaveric dissections and surgical cases through a minimally invasive, quick, and safe approach. Inflation of the Fogarty Balloon caused interruption of blood flow in 100% of cases. CONCLUSIONS Temporary occlusion of the paraclival ICA performed through the endoscopic endonasal route with the aid of a Fogarty Balloon Catheter may be another maneuver for dealing with intraoperative ICA control. Further clinical studies are required to prove the efficacy of this method.
