RESUMEN
<p><b>OBJECTIVE</b>To explore the techniques and outcomes of the surgical treatment for varicose vein.</p><p><b>METHODS</b>Totally 2 200 patients with varicose vein received surgical treatment in our hospital from July 2000 to January 2006. The latest techniques for endovenous occlusion were used for most cases, among which 1 802 cases were treated with endovenous laser treatment (EVLT) combined with transilluminated powered phlebectomy (TIPP), 82 cases with radiofrequency endovenous occlusion (RFO) combined with TIPP, and 218 cases with limited invaginated vein stripping and foam sclerotherapy. The remaining 98 cases were treated with laser, radiofrequency or ligation for saphenous vein trunk, and with resection, electric coagulation, and transfixation for vein clusters as additional methods. Perforators were also cut and ligated as well.</p><p><b>RESULTS</b>Satisfied surgical results were obtained in all cases. The average operative time was 40 minutes (range 20-78 minutes).</p><p><b>CONCLUSIONS</b>Limited invaginated vein stripping, EVLT, and RFO can be used to treat saphenous vein reflux. Surgical resection, transfixation, electric coagulation, and sclerotherapy are reasonable options for vein cluster or tributaries. Transection and ligation of the perforators are important. TIPP is ideal for the treatment of vein clusters.</p>

<p><b>OBJECTIVE</b>To explore the effective and safety of carotid endarterectomy (CEA) in the treatment of severe stenosis of internal carotid artery.</p><p><b>METHODS</b>The clinical data of 95 patients with internal carotid artery stenosis and treated by CEA in our hospital from October 1998 to October 2006 were retrospectively analyzed. Transient ischemic attack (TIA) was found in 65 patients and cerebral infarction in 21 patients before operations. Diagnoses were confirmed by selective angiography, and > 70% stenosis of internal carotid artery was found in all patients and > 95% stenosis was found in 50 patients. Stenosis or occlusion of the contralateral carotid artery was also found in 35 patients. Coronary artery stenosis was confirmed in 43 patients with preoperative coronary angiography. CEA and coronary artery bypass grafting (CABG) were simultaneously performed in 18 patients.</p><p><b>RESULTS</b>After the operation, the clinical symptoms significantly improved in all patients. One case experienced hypoglossal nerve injury. One patient died of heart attack during follow-up.</p><p><b>CONCLUSION</b>CEA is an effective and safe treatment for severe stenosis of internal carotid artery.</p>
