New Surgical Approach (new + surgical_approach)
Selected AbstractsThe "Button Inside" Technique for the Aortic Root Replacement: A Modified Button TechniqueJOURNAL OF CARDIAC SURGERY, Issue 4 2006Carlo Canosa M.D. Anastomosis of the coronary buttons is performed from the inside of the composite valve graft previously including the coronary buttons in the composite valve graft. Reduced tension is present between coronary arteries and the composite valve graft once the heart is beating and the systemic pressure is increasing. In this way coronary buttons are reinforced directly by the composite aortic wall graft prosthesis. The coronary ostia are perfused with lower tension at the site of the coronary anastomoses. No bleeding from the suture line of the coronary buttons occurs using this new surgical approach.

In what follows, we report the long-term results of our new surgical approach and discuss the role of these transplantations. We also review and report some complications that can be caused by ATFV. Finally, we discuss the ATFV technique as a contribution to the phonosurgery of the future. Study Design: Prospective study. Methods: We were able to obtain long-term results from 10 volunteer cases (2 female and 8 male, age: 15,71, mean 46.5 years old) who could be followed up for at least 3 years after transplantation. All were cases of pathologic sulcus vocalis. We measured maximum phonation time (MPT) and carried out pre- and postsurgical clinical observation and laryngeal stroboscopy in all cases. These measurements and observations were made before the ATFV and at 6 months, 1 year, 2 years, and 3 years after surgery. Results: In stroboscopic observation 1 year after the ATFV, satisfactory glottal closure and excellent mucosal wave were observed for all cases, and there was no case with hyperadduction of the false vocal folds. MPT measures remained at an improved level 2 years and 3 years after the transplantations. Paired-sample t tests showed that the improvement relative to preATFV levels was significant for all postsurgical measurements up to 3 years. Conclusions: We conclude that ATFV is a successful surgical procedure for sulcus vocalis and scarred vocal folds. Other phonosurgical clinical applications may also be envisioned. [source] 2146: Intracorneal lenses for the treatment of presbyopia using femtosecond laser: visual outcomes and safetyACTA OPHTHALMOLOGICA, Issue 2010IG PALLIKARIS Purpose To investigate the visual outcomes and safety of Intracorneal lenses (Flexivue Micro-Lens, Presbia, CA)) for the treatment of presbyopia. Methods This was a prospective clinical study. An intrastromal corneal tunnel was created using femtosecond laser (Intralase 150, AMO , CA). The lens was inserted within the cornea tunnel of the non-dominant eye of 10 presbiopian patients. Mean age was 51,23 years old ± 3,11 (5 males and 5 females). The follow-up was up to 12 months. Results In the operated eye, mean uncorrected visual acuity for distance (UVA-D) preoperatively, one day, one week one month, three months and six months, and 1 year after surgery was 20/20, 20/40, 20/40, 20/32, 20/32, 20/32 and 20/32 respectively, whereas for near (UVA-N) was 20/50, 20/40, 20/30, 20/30, 20/25, 20/25 and 20/30. Binocular far vision was not altered. No tissue alterations of the cornea were found using corneal confocal microscopy. No intra or post-operative complications were demonstrated up to one year after surgery. Conclusion Intracorneal lenses for the correction of presbyopia using femtosecond laser seems to be a safe and effective method to correct presbyopia in patients aged between 45 to 55 years old; a target group which is considered too old for refractive laser surgery and too young for clear lens extraction. Longer follow-up and a larger population are necessary in order to draw more significant results of this new surgical approach for the treatment of presbyopia. Commercial interest [source] Contemporary Surgical Treatment for Atrial FibrillationPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 7p2 2003A. MARC GILLINOV Traditional surgical treatment of AF is the Cox-Maze III procedure. The Cox-Maze III procedure cures AF in >90% of patients and virtually eliminates the risk of stroke. Recent understanding of the importance of the pulmonary veins and left atrium in the pathogenesis of AF has resulted in the development of new surgical approaches. New operations to ablate AF use alternate energy sources (radiofrequency, microwave, cryothermy) and simplified left atrial lesion sets. These operations cure AF in 70,80% of patients. This article describes contemporary and emerging surgical approaches to AF, synthesizes results of these operations, and proposes a strategy for choice of operation based on patient presentation.
