Objective To investigate the clinical and imaging features of right-side non-thrombotic iliac vein compression syndrome(NIVCS),and to evaluate the efficacy of endovascular treatment.Methods The clinical data and imaging materials of lower extremity venography from January 2019 to February 2024 in Affiliated Nanjing Gaochun People's Hospital,Jiangsu University were retrospectively analyzed.The patients with clinically diagnosed right-side NIVCS who received endovascular treatment were selected for this study.The clinical features and imaging findings,technical success rate,postoperative clinical improvement,and stent patency rate were analyzed.Results The median follow-up time was 30.2 months(3-58 months).A total of 24 patients with right-side NIVCS(aged 42-73 years)were enrolled in this study.Of the 24 patients,22(91.7％)were male and only 2(8.3％)were female,the proportion of male was significantly higher than that of female(P＜0.001).According to Clinical Etiologic Anatomic Pathophysiologic(CEAP)grading,14 patients were of grade C3,9 patients were of grade C,and one patient was of grade C.Imaging examination showed that the most frequent site of compression was the proximal end of the external iliac vein(15/24,62.5％),the second frequent site of compression was the proximal part of the common iliac vein bifurcation(5/24,20.8％).The most common external pressure structure was the internal and external iliac arteries(14/24,58.3％),the second common external pressure structure was external iliac artery and sacrum(5/24,20.8％).The technical success rate was 100％,and only one stent was implanted in each patient(diameter of 12-14 mm and length of 80-90 mm).The most commonly used stent was the Smart control(19/24,79.2％).During follow-up period,the remission rate of edema was 85.7％(18/21),the ulcer healing rate was 100％(1/1),and all stents remained patent.Conclusion Right-side NIVCS is more commonly seen in male patients.Because the compression site is usually located at the distal end of iliac vein,thus,the implanted stent may rarely affect blood flow in the contralateral iliac vein.Therefore,endovascular treatment is a safe and effective method for right-side NIVCS.

Objective To investigate the clinical application value of contrast-enhanced chest CT in the detection of responsible vessels for hemoptysis before selective arterial embolization(SAE).Methods The clinical data of 74 patients with hemoptysis trea-ted with interventional therapy and preoperative contrast-enhanced chest CT and digital subtraction angiography(DSA)were ana-lyzed retrospectively.The responsible vessels were identified and then embolized via angiography.The detection of the responsible vessels via preoperative contrast-enhanced chest CT was analyzed.The patients were followed up to observe the efficacy and compli-cations,and the influencing factors of interventional efficacy and recurrence were analyzed.Results A total of 245 responsible ves-sels were detected by preoperative contrast-enhanced chest CT,including bronchial arteries(n=178),ectopic bronchial arteries(n=10)and non-bronchial systemic artery(NBSA)(n=57),which could accurately show the anatomical information of responsible vessels.A total of 4 posterior intercostal arteries were missed.The diagnostic accuracy was 98.4％(245/249).All patients were followed up for 12 to 25.6 months.The immediate hemostasis rate was 93.2％(69/74)and the effective rate was 79.7％(59/74),respectively.The factors affecting the efficacy were bronchial artery to pulmonary circulation fistula,pleural thickening at the bleeding site,and underly-ing lung disease.Among the 59 patients with effective treatment,underlying lung disease was the influencing factor for postoperative recurrence.Conclusion Contrast-enhanced chest CT can provide anatomical information about the responsible vessels for interven-tional therapy of hemoptysis,improving surgical efficiency and reducing the recurrence rate of hemoptysis.

Objective To investigate the safety and efficacy of Embosphere microsphere in the treatment of massive hemoptysis during bronchial arterial embolization(BAE).To analyze the factors influencing the recurrence by Cox regression model.Methods Ninety patients with massive hemoptysis who underwent BAE using Embosphere microsphere were included.The immediate hemo-stasis rate within 24 hours,clinical success rate and prognostic factors were statistically analyzed.Results The immediate hemosta-sis rate within 24 hours was 94.4％(85/90).The clinical success rate was 56.7％(51/90).Cumulative hemoptysis-free recurrence con-trol rates at 6 months,1 year and 2 years postoperative were 81％,78％and 57％,respectively.Cox regression model analysis showed that the variables associated with recurrence were long-term hemoptysis,lung cancer,tuberculosis and lung destruction.Conclusion Embosphere microsphere are safe and effective embolic particles in the treatment of massive hemoptysis during BAE.Risk factors for hemoptysis recurrence include long-term hemoptysis,lung cancer,tuberculosis and lung destruction.

The number of projects and the amount of sponsoring funds have been increasing during the past years.Conventional research branches are respiratory tumor and digestive tumor.Emerging research branches are lung transplantation and lung preservation.Underdeveloped research branches are acute lung injury and acute respiratory distress syndrome and thymic tumor.The position and academic impact of domestic thoracic surgery has been more valuable with the increasing number,quality and achievements of SCI papers.Therefore,international cooperation and megamergers should be encouraged and more attention should be paid to the censorship,implementation and achievements to optimize the value of projects.The aim of this article is providing important information on projects sponsored by National Nature Science Foundation of China(NSFC) in the field of general thoracic surgery,promoting the development of thoracic surgery of China.

OBJECTIVETo investigate the clinical effects of manipulative reduction and percutaneous locking compression plate internal fixation for the treatment of mid-distal tibiofibula shaft fractures.

METHODSFrom January 2006 to October 2009,46 patients suffering from mid-distal tibiofibula shaft fractures were treated with closed manipulative reduction and LCP, involved 27 males and 19 females with an average age of 39 years old ranging from 17 to 56 years. According to AO classification, there were 12 cases of type A, 24 of type B, 10 of type C. The duration of visiting hospital were from 2 hours to 3 days after being injured for these patients. The injured limbs of the patients were swollen and painful,even with bony crepitus. The wound, function of the injured limb and union of fractures were observed after operation.

RESULTSAll the patients were followed up from 12 to 18 months (averaged 15 months). It was found that the wound of all patients had primary healing without any infection. The fracture healing time was 12 to 18 weeks (means 14 weeks). The results were excellent in 40 cases,good in 4 and fair in 2.

CONCLUSIONLess invasive, more stable fixation, shorter healing time and better functional rehabilitation are observed in the treatment of mid-distal tibiofibula shaft fractures after manipulative reduction and percutaneous locking compression plate internal fixation.
