Objective To evaluate the feasibility of combined subfascial endoscopic perforator surgery (SEPS) and Muller's phlebectomy for treatment of valvular insufficiency of the lower limbs by dividing perforating veins. Methods With ascending phlebography, insufficiency of perforating veins of the lower limbs were identified in 41 lower extremities with varicosity admitted from September 2005 to May 2006. In 31 limbs randomly chosen SEPS was performed to excise insufficient venous perforators under the deep fascia, combined with Muller's phlebectomy to strip the superficial varicose veins without encroaching on the great saphenous vein. In the same period, 10 diseased limbs, in which traditional great saphenous vein phlebectomy was performed to serve as controls. Results All the varicose veins disappeared postoperatively, with pigmentation lightened and ulcer healed. No recurrence was found after 5-11 months. Compared with the control group, the operation time, the number of sutures on the surgical wounds and hospital stay time were averagely decreased 1.5h, 4.3 and 4.8d, respectively (all P

Objective:To analyze the operative methods and complications for surgical resection of carotid body tumor (CBT). Method:Clinical data of 29 patients underwent CBT resection from Jan 2007 to Apr 2015 were retrospectively studied. Result:Five out of 29 patients got bilateral CBT, the others had unilateral lesions, totally 34 CBT resection were performed. Tumor completely dissected without carotid artery clamping and reconstruction in 18 procedures, tumor resection combined with external carotid artery resection in 16 procedures, 9 out of these 16 procedures combined with internal carotid artery resection. The internal carotid artery was reconstructed with autologous greater saphenous vein in 4 procedures, with artificial graft in 3 procedures, and internal carotid artery ligation without reconstruction in 2 procedures. There was no patient death during perioperative period, cerebral infarction happened in 1 patient and cranial nerve injury occurred in 12 cases. Conclusion:Carotid artery resection and reconstruction is very common during CBT resection, surgeon must be familiar with the methods of carotid artery reconstruction, and the most common complication of carotid body tumor resection is the cranial nerve injury.
