Video-assisted thoracoscopic left sympathectomy for the treatment of congenital long QT syndrome / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To assess the feasibility, safety and effectiveness of video-assisted thoracoscopic sympathectomy (VATS) for the treatment of congenital long QT syndrome.</p><p><b>METHODS</b>Under general anaesthesia, pleural cavity was entered via two or three small incisions in the left intercostal space. The left thoracic sympathetic chain was identified and resected from T2 approximately T5. The lower one at the third of the left stellate ganglion was also resected.</p><p><b>RESULTS</b>VATS resulted in a significant shortening in corrected QT intervals in three patients. The average QT interval of the four patients was 537.5 ms before VATS and 512.5 ms after VATS. The heart rate of the patients remained unchanged. There were no major peri-operative complications apart from mild ptosis of the left upper eyelid in one patient who recovered in the following days. The syndrome recurred in one patient in syncopal events in four months after VATS.</p><p><b>CONCLUSION</b>VATS is a safe as well as an effective technique for the treatment of congenital long QT syndromes.</p>
