Objective To discuss the safety and validity of pulmonary endarterectomy (PEA) for chronic thromboembolic pulmonary hypertension (CTEPH) patients with severe right heart failure (RHF). Methods PEA procedures were performed on 36 patients in Fu Wai Hospital from January 2015 to April 2016. There were 28 males and 8 females, with a mean age of 46.56±11.85 years. According to the New York Heart Association (NYHA) cardiac function classification, 36 patients were divided into preoperative severe RHF group (grade Ⅲ-Ⅳ,n=28) and preoperative without severe RHF group (grade Ⅱ,n=8). Hemodynamic parameters before and after PEA were recorded and 3-18 months' follow-up was done. Results All the patients having PEA surgeries had an obvious decrease of mean pulmonary arterial pressure (from 49.53±13.14 mm Hg to 23.58±10.79 mm Hg) and pulmonary vascular resistance (from 788.46±354.60 dyn·s/cm5 to 352.89±363.49 dyn·s/cm5, bothP<0.001). There was no in-hospital mortality among all the patients. Persistent pulmonary hypertension occurred in 2 patients, perfused lung in 2 patients, pericardial effusion in 2 patients. No mortality was found during the follow-up period. All patients improved to NYHA grade Ⅰ-Ⅱ (WHO grade Ⅰ-Ⅱ), and only 2 patients remained in the NYHA grade Ⅲ (P<0.01). Conclusion The CTEPH patients having PEA surgeries had an obvious improvement in both their hemodynamics results and postoperative heart function, which in return could improve their quality of life.
ObjectiveTo compare the clinical efficacy of video-assisted thoracoscopy and thoracotomy for the treatment of encapsulated tuberculous pleurisy. MethodsWe retrospectively analyzed the clinical data of 99 patients who had underwent surgery for encapsulated tuberculous pleurisy within 3 months of disease onset in our hospital from January through December 2013. Based on the surgical mode, patients were assigned to a video-assisted thoracoscopy group, including 49 patients (35 males and 14 females, a mean age of 26.78±9.36 years), to receive video-assisted thoracoscopic pleurectomy; or a thoracotomy group, including 50 patients (31 males and 19 females, a mean age of 31.84±11.08 years), to receive conventional thoracotomic pleurectomy. The first 43 patients in the video-assisted thoracoscopy group received thoracic catheter drainage, with the drainage volume of 659.08±969.29 ml; the first 48 patients in the thoracotomy group received thoracic catheter drainage, with the drainage volume of 919.03±129.97 ml. The clinical effects were compared between the two groups. ResultsAll the patients in the video-assisted thoracoscopy group completed thoracoscopy without conversion to thoracotomy. The surgery duration and postoperative intubation time were shorter in the video-assisted thoracoscopy group than those in the thoracotomy group (surgery duration:103.00±53.04 min vs. 127.06±51.60 min, P<0.01; postoperative intubation time 3.02±0.83 d vs. 3.94±1.25 d, P<0.01). At the end of 6 months of follow-up, the forced expiratory volume in one second (FEV1>) was 2.83±0.64 L in the thoracos-copy group and 2.25±0.64 L in the thoracotomy group (P<0.01); forced vital capacity (FVC) was 3.02±0.72 L in the thora-coscopy group and 2.57±0.79 L in the thoracotomy group (P<0.05); and maximal voluntary ventilation (MVV) was 93.90± 15.86 L in the thoracoscopy group and 80.34±17.06 L in the thoracotomy group (P<0.01). ConclusionThoracoscopic surgery is feasible for patients with encapsulated pleurisy within 3 months of onset. Furthermore video-assisted thoraco-scopy will be superior to thoracotomy.
ObjectiveTo compare the effectiveness of radiofrequency ablation (RFA) combined with transilluminated powered phlebectomy (TIPP) vs. high ligation and stripping (HLS) combined with TIPP in patients with varicose veins of lower limbs.MethodsA retrospective analysis was made on the clinical data of 190 patients (206 limbs) of varicose veins of lower limbs who underwent surgical treatment in our hospital from December 2017 to July 2018, of them 88 patients (96 limbs) in RFA combined with TIPP group and other 102 patients (110 limbs) in HLS combined with TIPP group. The treatment effectiveness and quality of life was assessed with venous clinical severity score (VCSS) and chronic venous insufficiency questionnaire (CIVIQ-14) in three months and one year after surgery. Doppler ultrasound was used to evaluate the closure of great saphenous vein.ResultsBaseline characteristics were similar between the two groups (P>0.05). The RFA combined with TIPP group was better than the HLS combined with TIPP group in operation time, intraoperative bleeding, hospital stay time, postoperative bed time, resumption time of activities, as well as incidences of skin induration and limb numb (P<0.05). Occlusion rates of great saphenous vein in 3 months was 93.8% (90/96) in the RFA combined with TIPP group and 97.3% (107/110) in the HLS combined with TIPP group, and in one year was 91.7% (88/96) and 97.3% (107/110) respectively, there was no significant difference between the two groups at the same time point (P>0.05). The VCSS scores and CIVIQ-14 scores also improved significantly in two groups in 3 months and 1 year follow up (P<0.05), but there was no significant differences between the two groups at the same time point (P>0.05).ConclusionsRFA combined with TIPP is an effective method for the treatment of varicose veins of lower limbs. Compared with HLS, RFA has the same good effectiveness and quality of life, but it has the advantages of short operation time, rapid postoperative recovery, and less postoperative complications.
ObjectiveTo investigate the risk factors of carotid endarterectomy.MethodThe literatures about carotid artery stenosis in the past 30 years were screened through literature retrieval, and the study of surgical risk factors related to carotid artery stenosis were reviewed.ResultsThere were many risk factors associated with the carotid endarterectomy, including demographic, underlying disease, surgical factors, perioperative management, and so on. However, the risk factors analysis were not comprehensive enough in the current study, so there was still lack of effective methods to predict the surgical risk of carotid artery stenosis.ConclusionTo fully understand the risk factors of carotid endarterectomy and to establish a multi-factor prediction model is the direction of further research.

Objective To investigate the influencing factors for restenosis after femoral endarterectomy in treatment of arteriosclerosis obliterans at femoral artery . Methods A total of 103 patients with arteriosclerosis obliterans at femoral artery who underwent femoral endarterectomy from Jan. 2012 to Jan. 2017 in our hospital were retrospectively selected as subjects of this study, to compare the clinical feathers between restenosis group and patent group, and then exploring the influencing factors for restenosis after femoral endarterectomy. Results Thirty-six patients (35.0%) suffered from restenosis after femoral endarterectomy. Patients in the restenosis group had a high proportion of high smoking and diabetes mellitus, and high level of low density lipoprotein than those corresponding indexes of the patent group (P<0.05). Results of Cox proportional hazard model showed that, diabetes mellitus 〔RR=3.338, 95% CI was (1.003, 11.113), P=0.049〕 and high level of low density lipoprotein 〔RR=3.311, 95% CI was (1.166, 9.397), P=0.024〕 were independent risk factors for restenosis after femoral endarterectomy. Conclusions Monitoring of high-risk factors like controlling blood glucose strictly and strengthening statin treatment should be done to reduce the risk of restenosis after femoral endarterectomy for patients with arteriosclerosis obliterans at femoral artery.
Objective To compare the long-term efficacy of carotid artery stenting (CAS) and carotid endarterectomy (CEA) in the treatment of carotid artery stenosis by meta-analysis. Methods PubMed, Embase, Medline, Cochrane Library, China National Knowledge Infrastructure, Wanfang database, Chongqing VIP database, and SinoMed were searched, for randomized controlled trials comparing the efficacy of CAS and CEA in the treatment of carotid artery stenosis published before September 2nd, 2021. Stata 15.1 software was used to analyze the long-term outcome data, including any stroke, ipsilateral stroke, fatal or disabling stroke, any death, combined endpoint of stroke or death, and carotid artery restenosis. Results A total of 20 English articles from 9 studies were included, involving 8551 patients (4658 in the CAS group and 3893 in the CEA group). The medians of the follow-up time of these studies were 2-10 years. The meta-analysis showed that the risks of any stroke [hazard ratio (HR)=1.33, 95% confidence interval (CI) (1.16, 1.52), P<0.0001], ipsilateral stroke [HR=1.26, 95%CI (1.02, 1.55), P=0.034], and the combined endpoint of stroke or death [HR=1.17, 95%CI (1.02, 1.33), P=0.021] in the CAS group were significantly higher than those in the CEA group, while the risks of fatal or disabling stroke [HR=1.19, 95%CI (0.94, 1.51), P=0.152], any death [HR=1.06, 95%CI (0.95, 1.18), P=0.302], and restenosis [HR=1.20, 95%CI (0.96, 1.49), P=0.111] were not significantly different between the CAS group and the CEA group. Conclusions CAS and CEA have similar risks in terms of long-term fatal or disabling stroke, death, and carotid artery restenosis, but the long-term risks of any stroke, ipsilateral stroke and combined endpoint of death or stroke of CAS are higher than those of CEA. CEA is still the preferred non-drug method for carotid artery stenosis.
