Thirty seven patients with venous thromboembolic disease in puerperium were admitted to hospital from January 2005 to December 2008; the clinical data of patients were retrospectively analyzed.The average age of patients was (33 ± 6)years (21 -42 years); the average onset time was ( 10 ± 6) d( 1 -50 d) after delivery.Seven patients had vaginal birth and 30 by cesarean section.The risk factors included pregnancy,cesarean section,age,infection,thrombophilia.All were diagnosed by ultrasonography and treated by anticoagulant,antiplatelet and thrombolytic therapy in the acute phase,followed by wearing elastic compressive stockings for more than 2 years.Pulmonary embolism was diagnosed in 8 patients by CT angiography,in 7 of whom inferior vena cava filter was administrated emergently.The patients were followed up for (29 ± 10)months ( 12 -60 months); during the follow-up 3 developed deep vein post-thrombosis syndrome,while others kept in good condition.The results indicate that initial anticoagulant,antiplatelet and thrombolytic therapy followed by elastic compressive stockings administration is effective for venous thromboembolic disease during puerperium.

ObjectiveTo evaluate the efficacy, feasibility and safety of CT guided percutaneous 125Ⅰ seeds implantation in elderly patients of stage Ⅰperipheral non-small cell lung cancer ( NSCLC ).MethodsClinical data of 16 elderly peripheral stage Ⅰ NSCLC patients ( 10 squamous carcinoma and 6adenocarcinoma;13 stage ⅠA and 3 stage ⅠB ) who received radioactive 125Ⅰ seeds implantation because of refusal or being unsuited to operation or external radiotherapy were retrospectively analyzed. Prescribed dose was 140 - 160 Gy. Under CT guidance, 125Ⅰ seeds were implanted percutaneously into tumors for interstitial radiotherapy according to treatment plan system. ResultsMean number of 125Ⅰ seeds each patient received was21.1. 12 complete response (CR) and 4 partial response (PR) were achieved. Total response rate ( CR + PR) was 100％. 100％ patients completed 10 to 56 months of follow-up, 15, 13, 8 and 6 patients completed 1-, 2-, 3-and 4-years'follow-up, respectively. The median local progression free time was 14months. The 1-,2-,3-and 4-year overall survival rate were 60％, 54％, 50％ and 33％, respectively (median:14 months). 7 cases died of non-tumor disease and 5 died of metastasis. No severe complications were observed. ConclusionsCT guided 125Ⅰ seeds implantation is a safe, reliable and effective radical treatment method for elderly stage Ⅰ peripheral NSCLC patients, who refuse to or are unsuitable to operation or external radiotherapy.

Objective To analyse the management of splanchnic artery aneurysms by open surgery and endoluminal therapy. Methods The clinical data of 10 splanchnic artery aneurysm patients (four male, six female) hospitalised from January 2002 were analysed retrospectively. The average age was (56 ± 13) years (28 - 74). Surgical or endoluminal treatment for six cases of splenic artery aneurysms or pseudoaneurysms were applied, among which multiple splenic artery aneurysms was found in one, and aberrant aneurysms at the proximal section of the splenic artery originating from a spleno-mesenteric trunk was found in three, splenic artery pseudoaneurysm in one and single aneurysm with normal splenic artery in anatomy in one. Besides, there were two superior mesenteric artery aneurysm, one of tuberculous celiac artery pseudoaneurysm and one renal artery aneurysm. Results The tuberculous celiac artery pseudoaneurysm was successfully managed by deploying a stent-graft endoluminally. One case was converted to open surgery after the splenic artery aneurysm was only paitially covered by a stent-graft. The other 8 cases were successfully treated by open surgery. All of the operations are successful. All patients were followed up from three months to six years, during which no death or other severe complications occurs. Conclusions The splanchnic artery varies from one to another anatomically. Preoperative CT scan or digital substraction angiology are helpful for the diagnosis of the splanchnic arterial aneurysms and choosing an appropriate management. Conventional open surgery is effective and reliable, while endoluminal therapy is a minimally invasive alternative.

Objective To evaluate endoluminal repair and preoperative management for acute Standford type B aortic dissection complicating massive hydrothorax. Methods The clinical data of 27 patients (23 males, 4 females) hospitalized from January 2003 to December 2008 were analysed retrospectively. The average age was 47 ±9 years (35 ～70). Eleven patients had bilateral huge hydrothorax (40. 7% ) , while 13 had left hydrothorax (48. 1% ) and 3 had right hydrothorax (11. 1% ) only, and in 2 of them with additional pericardial effusion (7.4% ). SaO2 was below 90% in all cases. All patients underwent emergency endovascular repair. For control of massive hydrothorax found by CT or chest fluoroscopy, puncture drainage or tube drainage were administrated postoperatively. Results All the 27 operations were successful, and there was no perioperative mortality. Three type Ⅰ and one type Ⅳ endoleaks occurred but disappeared in one month. Hydrothorax disappeared 28 days to 3 months postoperatively in all patients, of which 5 cases had puncture drainage (18.5%) and 1 case had tube drainage ( 3. 7% ). Mean follow-up was 30 ± 20 m ( 6 ～ 78 m ) after endovascular management. Complications included pleural thickening (6 of 27, 22. 2% ) , pulmonary atelectasis (2 of 27, 7. 4% ) , and lung consolidation combined with chest dent (2 of 27, 7. 4% ). Conclusions Emergency endovascular therapy is safe and effective for acute Stanford type B aortic dissection with massive hydrothorax. Drainage of hydrothorax after stent-graft deployment is a must for the patient suffering from severe respiratory failure.

Objective To evaluate long-term outcome of simultaneous kissing sirolimus-eluting stent (SKS) technique versus single sirolimus-eluting stent (SSS) technique for percutaneous treatment of true coronary bifurcation lesions in large-size vessels.Methods This randomized study assigned 190 patients with a coronary bifurcation lesion to simultaneous kissing stenting (SKS) in both main and side branches and 190 patients to main vessel stenting only (SSS).The endpoints included restenosis,death,non-fatal myocardial infarction,target-lesion revascularization (TLR),stent thrombosis,success rate of percutaneous coronary intervention (PCI) and the operation duration.Results During 1-year follow-up,the SKS group and the SSS group had similar incidences of overall re stenosis [30 ( 15.8 ％ ) vs.24 ( 15.2 ％ ),x2=0.000,P＜0.05],mainbranch restenosis [20 ( 10.5％ ) vs.16 ( 10.1％ ),x2=0.003,P ＞ 0.05];side-branch restenosis [13 ( 6.8％ )vs.23 ( 14.6％ );x2=4.73,P＜0.05];death [2 ( 1.1％ ) vs.1 ( 0.6％ ),x2=0.026,P ＞ 0.05],non-fatal myocardial infarction [4 (2.1％ ) vs.2 ( 1.3％ ),x2=0.034,P ＞ 0.05],TLR [23 ( 12.1％ ) vs.20 ( 12.7％ ),x2=0.000,P ＞ 0.05] and stent thrombosis [4 (2.1％ ) vs.2 ( 1.3 ％ ),x2=0.034,P ＞ 0.05] and a shorter operation duration[(20 ± 8) min vs.(45 ± 9) min,t=1.98,P＜0.05] than the SSS group.Conclusion For true coronary bifurcation lesions in large-size vessels,SKS and SSS have similar long-term outcomes.The SKS group has a higher success rate of PCI and shorter operation duration.

Objective:To investigate the feasibility and safety of endovascular repair for traumatic thoracic aortic pseudoaneurysm.Methods:From Oct 2015 to Oct 2018, the clinical and followup data of 7 patients diagnosed as traumatic thoracic aortic pseudoaneurysm in Fuwai Hospital of Chinese Academy of Medical Sciences were analyzed retrospectively.Results:The patients average age was (51.2±11.0) years old. All patients underwent surgery in the hybrid operating room under general anesthesia. Two did thoracic endovascular aortic repair (TEVAR), three did TEVAR combined with chimney technique to reconstruct the left subclavian artery, and 1 had TEVAR combined with fenestration to reconstruct the left subclavian artery. One did TEVAR with left common carotid artery and left subclavian artery bypass. The mean operative time was (90.1±27.4) min, the mean postoperative hospital stay was (8.9±3.7) d, and the mean postoperative follow-up time was 42.4 months. All the patients received CTA reexamination of the aorta after 1, 6, 12 months and yearly thereafter. TypeⅠendoleak was found in one patient with chimney technique to reconstruct of left subclavian artery after operation. CT showed that the type Ⅰ endoleak disappeared 6 months after operation. There was no death, paraplegia or stroke during the perioperative period and follow-up period, and there was no aortic related reintervention.Conclusion:TEVAR is a safe and effective method for the treatment of traumatic pseudoaneurysm of thoracic aorta, and the early and mid-term results were satisfactory.

Objective:To evaluate the safety and feasibility of the in-situ needle fenestration combined with the in vitro physician modified fenestration technique to reconstruct supra-aortic branches during thoracic endovascular aortic repair (TEVAR) for aortic arch lesions requiring landing at Z0 and Z1.Methods:From Nov 2017 to Dec 2019, eighteen patients who underwent both the in-situ needle fenestration and the in vitro physician modified fenestration techniques to extend the proximal landing zone to Z0 and Z1 during TEVAR were included in our study.Results:Sixteen patients underwent in vitro physician modified fenestration ,two patients underwent in vitro physician modified fenestration to reconstruct both the left common carotid artery and the innominate artery. All eighteen patients received in-situ needle fenestration to preserve the left subclavian artery. Supra aortic branches were preserved in all patients (38/38, 100%). There was no Type Ⅰ endoleak. Type Ⅱ endoleak was found in four paitnets (4/18). Type Ⅲ endoleak occurred in one patient (1/18). Type Ⅳ endoleak in four patients (4/18). Type Ⅲ endoleak needed open aortic arch repair 6 months later. The median follow-up time was 12 months. One (1/18) died in 12 months and the other patients were doing well.Conclusions:The joint application of the in-situ needle fenestration and the in vitro physician modified fenestration to reconstruct supra-aortic branches during TEVAR for aortic arch pathologies requiring landing at Z0 and Z1 was satisfactory.

In order to require ideal proximal landing zone and durable long-term outcome, it is necessary to reconstruct the left subclavian artery(LSA) blood supply as much as possible in thoracic aortic endovascular repair(TEVAR). With the advent and progress of diverse assisted techniques and devices, several procedures for the reconstruction of the left subclavian artery have been developed and widely utilized, including surgical LSA bypass or transposition, chimney technique, periscope technique, fenestration and branched stent-graft, which have expanded the proximal landing zone and widened the indication for original TEVAR. This article describes the advantages and pitfalls of each revascularization methods. Anatomies of aortic arch and LSA, urgency and types of pathologies, proficiency of the surgeon with different revascularization techniques and pre-operative risk score of patient should be evaluated in procedure selection. In clinical application, patient-specific evaluations and individualized considerations are essential for initialize the therapeutic strategy and decision making.

Objective: To explore the safety and strategy of thoracic endovascular aortic repair (TEVAR) combining coronary artery bypass grafting (CABG) as one-stop performance in treating the patients with coronary artery disease (CAD) and thoracic aorta disease. Methods: A total of 20 patients received one-stop treatment of TEVAR combining CABG in our hospital from 2009-04 to 2016-01 were retrospectively analyzed. There were 18 male and the mean age of patients was (65.2±8.5, 51-82) years. The performance strategy and peri-operative management were studied. Results: There were 1/20 patient received 2 stents implantation in thoracic aorta and 19 received 1 stent in thoracic aorta those including 1 case with endovascular repair of abdominal aortic aneurysm, 1 with right iliac artery stent implantation and 1 with carotid endarterectomy at meanwhile. The average number of coronary artery bypass branch was (2.4±0.94, 1-4) and 10 (50%) patients received internal mammary artery grafting. The average in-hospital time in all 20 patients was (22.4±11.6, 8-58) days. There were 6 (30%) patients received blood transfusion; 1 (5%) having low cardiac output syndrome received extracorporeal membrane oxygenation (ECMO), then received the second thoracotomy for hemostasis due to excessive pleural effusion; 2 (10%) patients died at 30 days post-operation. 1 patient lost contact and 17 received clinical or telephone follow-up visit at the average of (13.4+13.6, 1-49) months; 2 patients died for cerebral hemorrhage at 12 and 49 months post-operation, the rest 15 had disappeared symptoms and improved quality of life, no operation related death occurred. Conclusion: TEVAR combining CABG as one-stop performance presented good mid-term effect in treating the patients with CAD and thoracic aorta disease; in otherwise, the operative time and risk might be increased by two step performance.

Objective To understand patient pathway and clinical characteristics of chronic diseases in urban areas of Shanghai. Methods A total of 10 002 residents were enrolled and assigned to the chronic disease group (including hypertension, diabetes, coronary heart disease, myocardial infarction, and ischemic stroke) and the non-chronic disease group. Body mass index,fasting blood glucose, triglyceride,total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol were tested.Difference of patient pathway and clinical characteristics of those chronic diseases was compared. Results Above chronic diseases were observed in 37.7% participants. About 2/3 diseases were confirmed and 80% patients were followed up in healthcare units not far away from home. Patients with coronary heart disease and myocardial infarction showed more outpatient visit to tertiary hospitals (P＜0. 05 ). However, patients with ischemic stroke had health check, rehabilitation and pharmacy done mainly in local healthcare centers (P＜0. 05 ). Diastolic blood pressure of patients visiting local doctors was significantly decreased (P＜0. 05). Conclusion Some differences in patient pathway were found in this study. Communication and cooperation between medical institutions should be intensified for effective chronic disease control.
