Objective:To evaluate the efficacy and safety in the treatment of the visceral artery aneurysms (VAAs) by Viabahn stent graft and the detachable coils combined with Onyx embolization.Methods:A retrospective study on clinical and follow up results of 46 patients in the treatment of visceral aneurysms (VAAs) from Jun 2012 to Jun 2018 was carried out.Result:In 18 patients of VAAs treated with Vabahn endovascular stent grafting, the aneurysm cavity was completely isolated after injection of contrast and the technical success rate was 100% (18/18). In 28 patients of VAAs treated with the detachable coils combined with Onyx embolization, the aneurysm cavities of 26 patients among the 28 cases were filled tightly. In 2 patients the aneurysm neck was still visible. The average follow-up period was (36.5±2.3) months by CTA. After treating VAAs with the Viabahn stent graft, the complete isolation rate and the patency of aneurysm bearing artery were respectively 100% (18/18) and 94.4% (17/18). When VAAs was treated with the detachable coils combined with Onyx embolization, the complete isolation rate and the patency of aneurysm bearing artery were respectively 85.7% (24/28) and 92.9% (26/28) (χ 2=3.915, P=0.048), the difference of the patency of aneurysm bearing artery between the two groups was no significant difference (χ 2=0.074, P=0.786). Conclusion:VAAs treated with Viabahn endovascular stent grafting or detachable coils combined with Onyx embolization are both safe and effective.

Crohn's disease (CD) is a chronic nonspecific intestinal inflammatory disease with unclear etiology and pathogenesis. At present, it is believed that CD can cause different degrees of metabolic abnormalities, and that the related metabolites also play an important role in the development and progression of the disease. In recent years, metabonomics is becoming more and more well-developed and has provided guidance for clinicians on rational nutritional support. Here is a review on the metabolic changes of multiple systems in CD patients, the application of metabonomics in CD diagnosis and treatment, and the research progress of clinical nutrition intervention.

Objective:To investigate the clinical efficacy of thoracic endovascular aortic repair (TEVAR) in treating Stanford type B traumatic aortic dissection (TAD).Methods:A retrospective case series study was conducted to analyze the clinical date of 26 patients with Stanford type B TAD admitted to Nantong First People's Hospital from June 2011 to December 2019. There were 21 males and 5 females, aged 35-83 years [(56.2±12.9)years]. All patients mainly suffered from chest and back trauma and were treated with TEVAR. The operation time, intraoperative blood loss, intraoperative heparin dosage, duration of ICU stay and postoperative organ complications were collected. The changes of brain natriuretic peptide, urea nitrogen and creatinine were compared before operation and at one day after operation. The CT angiography (CTA) was performed to mainly detect the location of stent, reverse tearing, paraplegia and internal leakage at 6 months after TEVAR. The aortic CTA was used to measure the maximum diameter of aortic dissecting aneurysm and true lumen diameter of distal aorta before operation and at 6 months after operation, and the diameter changes were compared to determine the aortic remodeling after TEVAR.Results:All patients were followed up for 6-36 months [(25.9±6.3)months]. The operation time was 60-200 minutes [(96.7±30.7)minutes], the intraoperative blood loss was 20-45 ml [(31.1±6.8)ml], the dosage of heparin was 0-0.53 mg/kg [(0.4±0.1)mg/kg], the postoperative ICU stay was 1-7 days [(4.7±1.3)days]. Seven patients developed pulmonary infections after operation and showed significant improvement after closed thoracic drainage, airway management and anti-infection treatment. Two patients had abnormal renal function after operation and received medical therapy for improvement. There was no significant difference in brain natriuretic peptide, urea nitrogen and creatinine between before operation and one day after operation ( P>0.05). At 6 months after operation, the CTA showed that the stent position was satisfactory and there were no serious complications such as reverse tearing and paraplegia. Of one patient with type I endoleak, the tumor did not further expand and his condition was stable. At 6 months after operation, the diameter of dissecting aneurysm [(34.4±5.0)mm] was smaller than that before operation [(38.2±5.6)mm], the true lumen of distal stent [(26.8±4.6)mm] was larger than that before operation [(22.6±6.0)mm] ( P<0.05 or 0.01). Conclusion:For Stanford type B TAD, TEVAR has no significant effect on cardiac function and renal function, with no severe complications and good aortic remodeling.

Wegener' granulomatosis is an autoimmune diseases, often involving the lung and kidney, has a high mortality rate in nontreatment patients. The low incidence and nonspecific features, often lead to misdiagnosis and delayed treatment. This paper reported the diagnosis and treatment of a 55-year-old female patient with primary Wegener' granuloma of the lung diagnosed by percutaneous lung biopsy of pulmonary nodules, and reviews the relevant literature.

In recent years, the corona virus disease 2019 (COVID-19) pandemic has had a huge impact on the global medical, political and economic fields. Since the beginning of the COVID-19 epidemic, our understanding of the impact of COVID-19 has grown exponentially. Recently, the COVID-19 epidemic has changed rapidly in China, and there has been controversy over how to carry out surgical operations for patients with lung neoplastic lesions. Some studies have shown that lung cancer patients undergoing surgery are more likely to experience respiratory failure and perioperative death after contracting COVID-19 than the general population, however, delays in cancer treatment are also associated with increased mortality among these patients. In particular, the novel coronavirus Omikron variant has a higher transmissibility and may escape the immunity obtained through the previous novel coronavirus infection and vaccination. In order to minimize the risk of novel coronavirus infection in surgical patients, it is necessary to develop new treatment guidelines, expert consensus and preventive measures. However, the current rapid change of the epidemic situation has led to insufficient time and evidence to develop guidelines and consensus. Therefore, thoracic surgeons need to evaluate specific patient populations at higher risk of severe complications before surgery and weigh the benefit of surgical treatment against the risk of novel coronavirus infection. We try to give some recommendations on lung surgery during the current domestic epidemic situation based on the guidelines and consensus of oncology and thoracic surgery organizations in different regions on lung surgery.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
