Objective To evaluate the immediate and mid-term effectiveness of hybrid procedures (combined open surgery and endovascular therapy) for multilerel femoral and popliteal artery occlusive disease. Methods Between June 2009 and June 2012, 22 cases of severe femoral and popliteal artery occlusive disease were treated by hybrid surgery. There were 15 men and 7 women with an age range of 52-78 years (mean, 66.2 years) and with a disease duration of 6 months to 5 years (mean, 1.5 years). Of 22 patients, 13 had a history of smoking; 8 were classified as Fontaine III and 14 as Fontaine IV. The complications included diabetes (8 patients), hypertension (16 patients), hyperlipemia (10 patients), coronary heart disease (11 patients), and chronic kidney failure (1 patient). Patency analyses were performed using Kaplan-Meier life tables and log-rank test. Results All patients underwent successfully procedures. The time of operation was 70-160 minutes (mean, 137 minutes). Acute myocardial infarction, hematoma of incision, fracture of stent, and stent thrombosis occurred in 1 case, respectively. At 6 months after surgery, the ankle brachial index (ABI), the transcutaneous oxygen pressure (TcpO2), and the average intermittent claudication distance were significantly increased when compared with preoperative ones [0.79 ± 0.33 vs. 0.32 ± 0.18, (42.7 ± 15.7) kPa vs. (17.6 ± 11.6) kPa, and (420 ± 80) m vs. (160 ± 54) m, P lt; 0.05]. The patients were followed up 6-24 months (mean, 14.5 months). The primary patency rate, primary assisted patency rate, and second patency rate were 77.3% (17/22), 90.9% (20/22), and 95.5% (21/22) respectively, showing no significant difference among them (P gt; 0.05). No significant difference was found in various-stage patency rates between patients at Fontaine III and IV (P gt; 0.05). Conclusion Hybrid procedures provide an effective treatment of multilevel femoral artery and popliteal artery disease while there is good outflow.
Objective To compare the early compl ications of carotid stenting (CAS) and carotid endarterectomy (CEA) in treatment of carotid artery stenosis. Methods Between January 2005 and December 2007, 63 patients with carotid artery stenosis were treated with CEA in 36 cases (CEA group) and with CAS in 27 cases (CAS group). There were 42 males and 21 females with an average age of 67.5 years (range, 52-79 years). The locations were the left side in 28 cases and the rightside in 35 cases. The carotid stenosis was 60%-95% (mean, 79%). The major cl inical symptoms were stroke and transient ischemic attack. The cranial CT showed old cerebral infarction in 24 cases, lacunar infarction in 22 cases, and no obvious abnormal change in 17 cases. The encephalon, heart, and local compl ications were compared between 2 groups within 7 days after operation. Results In CEA group, encephalon compl ications occurred in 3 cases (8.3%), heart compl ications in 2 cases (5.6%), and local compl ications in 5 cases (13.9%); while in CAS group, encephalon compl ications occurred in 8 cases (29.6%), heart compl ications in 1 case (3.7%), and local compl ications in 3 cases (11.1%). The encephalon compl ication ratio of CAS group was significantly higher than that of CEA group (χ2=4.855, P=0.028); and there was no significant difference in other compl ications ratios between 2 groups (P gt; 0.05). Conclusion CEA is the first choice to treat carotid artery stenosis.
