Objective To investigate the clinicopathological characteristics and surgical treatment of intrathoracic Castleman disease(CD). Methods Clinical data of 14 cases pathologically diagnosed as CD as analysed retrospectively. There were 6 males and 8 females, with an average age of 29 years(17-58). All were undergone surgical resection or biopsy. Among the 12 patients who had unicentric CD, 11 were performed open thoracotomy and lymphadenectomy with posterolateral or sternum approach, and one was treated by video assisted mini thoracotomy(VAMT). For the diagnosis of multicentric CD, one of the 2 patients had video assisted thoracic surgery(VATS) and wedge resection of the lung, and the other had video mediastinoscopy. Results No patient died perioperatively. All were successfully restored except two complications. One had dyspnea in the second postoperative day, as a result of the softening and collapse of bronchial wall in the entrance of the right main bronchus, which revealed by bedside fiberoptic bronchoscopy. One who had lymphadenopathy in the aortopulmonary window suffered from transient hoarseness after surgery. They recovered after symptomatic treatment finally. Regarding pathological classification, there were 11 cases of hyaline vascular type, 2 cases of plasma cell type and 1 case of mixed cellularity type. 13 cases were followed up for 8-110 months and longterm survive was achieved. No recurrence was observed in the 11 cases with unicentric CD and no relapse was occurred in the 2 cases with multicentric CD. Conclusion Both freezing pathology during operation and paraffin pathology postoperation are important for establishing the diagnosis. For unicentric CD, the clinical symptoms are significantly alleviated and it can be universally cured after operation. Multicentric CD needs multiple therapies after the diagnostic procedure and close follow-up.

Objective To compare the effects of epidural anesthesia with intubated anesthesia in the postoperative recovery of patients with thoracoscopic resection of lung bullae. Methods Sixty patients (53 males, 7 females, aged 16-65 years) undergoing thoracoscopic resection of unilateral pulmonary bullae in our hospital from December 2014 to December 2015 were randomly divided into two groups: a group A (epidural anesthesia group) received thoracic epidural block combined with intraoperative interthoracic vagus nerve block; a group B (general anesthesia group) received general anesthesia with double lumen endobronchial intubation and pulmonary sequestration. Postoperative anesthesia-related complications and postoperative recovery were recorded. Results Both of the two anesthesia methods could meet the requirements of operation. The patients with the vocal cord injury and sore throat in the group B were more than those in the group A. The difference was statistically significant in the incidence of sore throat (P<0.01) . Arterial partial pressure of oxygen (PaO2) in the group A was significantly higher than that of group B before lung recruitment (P<0.01). Compared with the group B, the group A had less visual analogue scale (VAS) score (P<0.05), earlier activity and feeding, less postoperative ICU and hospital stay (P<0.01). Conclusion Epidural anesthesia combined with intraoperative interthoracic vagus nerve block can meet thoracoscopic bullectomy surgery requirements with few complications and fast postoperative recovery.
Objective To evaluate the clinical efficacy and safety of endovascular therapy for spontaneous isolated superior mesenteric artery dissection (SISMAD). Methods The clinical data of 17 patients with SISMAD, who were treated at author's hospital during the period from March 2009 to May 2016, were retrospectively analyzed. According to the Sakamoto angiographic classification, patients were divided into typeⅠ (n=3), typeⅡ (n=5), and type Ⅲ (n=9). Three patients with type Ⅰ were treated with conservative treatment first, and then 2 were treated with endovascular therapy as the poor reaction. The other patients were treated with endovascular treatment right a way. Results Conservative treatment was success in 1 case, 16 patients were treated with endovascular treatment, the technical success rate was 100%, one stent was used in 11 patients and two stents were used in 5 patients, and the blood in the true lumen of superior mesenteric artery (SMA) restored, no major complications occurred. Seventeen patients were followed-up for 3-36 months (mean of 19 months) and the followed-up rate was 100%, no abdominal pain occurred in 17 cases, CTA showed that no dissecting aneurysm was observed and the stents were patent of SMA. Conclusion Interventional therapy is a safe and effective method for SISMAD.
ObjectiveTo investigate clinical characteristics and surgical treatment of patients with non-malignant esophageal-tracheal/bronchial fistula.?Methods?We retrospectively analyzed clinical data of 12 patients with non-malignant esophageal-tracheal/bronchial fistula who underwent surgical repair in Peking Union Medical College Hospital from January 2002 to October 2011. There were 6 males and 6 females with a mean age of 49.8 years (ranging from 32 to 72 years). There were 7 patients with esophagotracheal fistula，1 patient with esophagobronchial fistula，2 patients with gastro-bronchial fistula after esophagectomy for esophageal cancer，and 2 patients with esophageal diverticulum bronchial fistula. Nine patients underwent surgical repair via right thoracotomy approach，and 3 patients via left thoracotomy approach. Seven patients underwent esophageal fistula and tracheal fistula repair，1 patient underwent esophageal fistula and bronchial fistula repair，2 patients underwent gastric fistula and bronchial fistula repair，1 patient underwent esophagectomy, gastroesophageal anastomosis and left lower lobectomy, and 1 patient underwent esophageal diverticulum repair and left lower lobectomy.?Results?All the patients recovered well from surgery with no perioperative complication or in-hospital death，and resumed oral intake 7-10 days after surgery. Three months to 1 year postoperatively, regular examinations including upper gastroenterography and fibrobronchoscopy found no sign of tracheal/bronchial stenosis or esophageal stenosis，and no patients needed stent implantation or dilatation treatment. All the patients were followed up from 3 months to 10 years and had a good quality of life during follow-up.?Conclusion?Excluding malignant etiology and determining the exact fistula location are key points of clinical diagnosis for esophageal-tracheal/bronchial fistula. Adequate preoperative nutritional support and 1-stage surgical repair can lead to satisfactory clinical outcomes.
Objective To discuss the clinical effect and value of stent placement combined with mechanical aspiration thrombectomy for acute iliofemoral venous thrombosis with iliac vein occlusion. Methods From October 2004 to December 2011， interventional treatment were performed in 273 patients with acute iliofemoral venous thrombosis and iliac vein occlusion， including left side of 235 cases and right side of 38 cases. Antegrade femoral vein under local anesthesia， an 8-14F catheter was inserted into iliofemoral vein with the guidance of guide wire to aspirate thrombus directly， 53 patients used 18-24F large lumen sheath to aspirate thrombus. As for the femoralpopliteal vein thrombus， a “cross sheath” was inserted to affected iliac vein with the help of guide wire capture technique， a guide wire was introd-uced to popliteal vein， then a Fogarty balloon catheter was inserted and extracted thrombus to iliac vein， mechanical aspiration thrombectomy was performed again. After iliofemoral vein thrombus were removed completely， percutaneous transluminal angioplasty （PTA） and stenting were performed for stenosis or occlusion displayed by venography. Results Thrombus removal were completely cleared （degreeⅢ） in 219 cases （80.22%）， partly cleared （degreeⅡ） in 49 cases （17.95%）， and minimal cleared （degreeⅠ） in 5 cases （1.83%）. The effect of stent placement：were cured in 235 cases （86.08%）， excellent in 29 cases （10.62%）， mild in 2 cases （2.57%）， and invalid in 7 cases （0.73%）. Total effective rate was 99.27% （271/273）， the average days in hospital was 7.5 days. Tumescence and pain of affected limb disappeared or relieved after interventional therapy for 1-2 days. The followe up effect：3-6 months， 7-12 months， 13-24 months， and 25-36 months after treatment of iliac vein patency were 94.87%，93.73%，87.08%，and 84.13% respectively. Conclusion Mechanical aspiration thrombectomy combined with stent placement for acute lower extremity deep venous thrombosis and iliac vein obstruction is an effective and safe treatment for its notable therapeutic effect and the short hospitalization time.
Objective To study the effect of the intracavity thrombolysis, aspiration of debris, percutaneous transcathete angioplasty (PTA) and percutaneous transtuminl angioplasty and stenting (PTAS) on treating peripheral arterial obliterans disease (PAOD). Methods From May 1994 to May 2008, interventional treatment was performed in 285 patients with PAOD. Intracavity thrombolysis and aspiration of debris were performed in 63 patients suffering from acute arterial occlusion. Intracavity thrombolysis and PTA were performed in 61 patients suffering from arteriostenosis combined with acute occlusion. Intracavity thrombolysis, PTA and PTAS were performed in 161 patients suffering from chronic arteriostenosis occlusion. Results Total success rate was 98.25% (280/285). The success rate in intracavity thrombolysis and aspiration of debris was 96.83% (61/63), with 88.89% (56/63) of the blood vessels restored, 7.94% (5/63) of the blood vessels partially restored, and another 3.17% (2/63) failed. The success rate in intracavity thrombolysis and PTA was 85.25% (52/61). The success rate in PTA and PTAS was 98.14% (158/161). The total complication rate was 7.02% (20/285), of them the local thrombolysis and thromboclasis accounting for 7.94% (5/63), the local thrombolysis and PTA accounting for 14.75% (9/61), the PTA and stent implantation accounting for 3.73% (6/161). Conclusion Percutaneous transluminal treatment for stenotic and occlusive lesions of peripheral artery can effectively keep the blood vessel unobstructed for a long time and raise the haemodynamics index remarkably.
Objective To discuss the clinical effect and value of minimally invasive therapy on lower extremity deep venous thrombosis （DVT）. Methods The clinical data of 911 patients with acute lower extremity DVT from April 1998 to December 2011 were analyzed retrospectively. There were 489 males，422 females；the age ranged from 23-86 years old with （58.72±11.95） years old. Five hundred and sixty-eight patients occurred on the left leg，343 patients on the right leg. There were 487 cases of central type，166 cases of peripheral type，258 cases of mixed type. All the patients were implanted inferior vena cava filter under local anesthesia，then inserted an 8-14 F catheter via the femoral vein of the affected limbs to suck mechanically thrombus. Five hundred and twenty-seven cases of iliofemoral vein thrombus were inserted into sheathing canal with the help of technique of guide wire griped. The guide wire could be plugged into femoral vein，even more far，with the help of sheathing canal. Following the guide wire，a diameter-10 mm balloon catheter was used to pull the thrombus to iliac vein，with the watching of DSA，so it could be sucked from iliac vein. Before sucking thrombus，a diameter-12 mm balloon was put into the confluence of inferior vena cava and iliac vein，in case of thrombus fall off with blood flow to block inferior vena cava. Results Among 911 patients，423 cases were only treated by sucking thrombus，275 cases sucking thrombus plus endovascular thrombolysis，91 cases sucking thrombus plus endovascular thrombolysis plus percutaneous transluminal angioplasty （PTA），122 cases sucking thrombus plus endovascular thrombolysis plus PTA plus stenting，the average hospital stay was 7.5 d. ① Discharge success rate：907 （99.56%） cases were successful by interventional therapy，4 （0.44%） cases were failed. Nine hundred and eleven patients were performed mechanical thrombus suction，which was 556 cases of gradeⅢ，142 cases of gradeⅡ，213 cases of gradeⅠ. Among 213 cases of gradeⅠ，there were 91 cases only underwent PTA treatment for economic reasons or advanced stage malignant tumors，122 cases underwent PTA plus stenting. The circumferences of affected limb and the differences of circumference of healthy and affected limbs knees above and below 15 cm at discharge were significantly smaller than those at admission （P＜0.01）. Twenty-seven cases underwent anticoagulation and thrombolytic therapy after operation，which occurred mild subcutaneous bleeding，gum bleeding，epistaxis，hematuria，and the symptoms were disappearance after adjusting drugs. All the patients did not appear to complications such as bleeding，vessel dissection. ② Follow-up effective rate：After 6 to 12 months follow-up，there were 714 （78.38%） cases of excellent，136 （14.92%） cases of good，57 （6.26%） cases of middle，4 （0.44%） cases of poor. After 13 to 24 months follow-up，there were 691 （76.18%） cases of excellent，151 （16.65%） cases of good，65 （7.17%） cases of middle；65 cases occurred restenosis that the PTA and stent placement was underwent again， blood flow of 58 cases completely restored，blood flow of 7 cases partly recovered，and the contrast agent didn’t retent. After 25 to 36 months follow-up，there were 681 （75.08%） cases of excellent，128 （14.11%） cases of good，98 （10.81%） cases of middle；98 cases of limb swelling were not satisfied，and the patients still had a sense of pain after walking，but the symptoms obviously improved as compared with preoperative symptoms，the patients were advised to wear stretch socks with no further interventional therapy. Conclusions Minimally invasive therapy on lower extremity DVT can eliminate thrombus from venous cavity more early，restore the unobstructed flow instantly，preserve the function of venous valve in a greater degree. It has an advantage of minimally invasive，less complications，and notable clinic effect of short-term and medium-term follow-up.
