RESUMO
Objective To observe the effect of transcatheter thrombectomy combined with catheter-directed thrombolysis(CDT)for treating acute medium-high and high risk pulmonary thromboembolism(PTE).Methods After placement of inferior vena cava filter,transcatheter thrombectomy combined with CDT were performed in 28 patients with acute medium-high or high risk PTE.After treatment,clinical symptoms improved or not was assessed,and interventional related complications were recorded.The outcomes of arterial blood gas analysis,coagulation function,blood routine test,pulmonary artery pressure(PAP)and right ventricular diameter/left ventricular diameter(RV/LV)were compared before and 72 h after treatment.Regular follow-up was performed,then PAP and the clearance of pulmonary arterial thrombosis were observed 1,3,6 months and 1 year after treatment during follow-up.Results Among 28 cases,significant improvement of clinical symptoms achieved in 26 cases after treatment,while 2 patients died of respiratory failure.Puncture site bleeding occurred in 4 cases and improved after conservative treatment.Compared with those before treatment,among 26 survived patients,blood pH,arterial oxygen pressure,fibrin degradation products and D-dimer increased while the heart rate,N-terminal pro-B-type natriuretic peptide,PAP and RV/LV decreased 72 h after treatment(all P＜0.05).During follow-up,compared with those before treatment,PAP decreased,while the clearance rate of pulmonary thrombosis increased 1,3,6 months and 1 year after treatment(all P＜0.05).No active bleeding nor recurrence of PTE happened.Conclusion Transcatheter thrombectomy combined with CDT was safe and effective for treating acute medium-high and high risk PTE.
RESUMO
Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.
RESUMO
Objective To explore the feasibility and safety of emergency interventional arterial embolization combined with percutaneous minimally invasive screw fixation in the treatment of pelvic fracture combined with hemorrhagic shock.Methods A retrospective analysis of 21 patients with pelvic fractures and hemorrhagic shock who were treated with emergency interventional arterial embolization combined with percutaneous minimally invasive screw fixation was performed.The percutaneous minimally invasive screw fixation was performed immediately after embolization.Results There were 18 of 21 cases with obvious arterial bleeding confirmed by femoral artery angiography.And the corresponding interventional embolization was performed.No obvious arterial hemorrhage was found in the other 3 cases who received suspicious hemorrhagic internal iliac arterial prophylactic embolization.The time-consuming of percutaneous minimally invasive screw fixation was no more than 90 min for each patient.There was no servious complication associated with arterial embolization after intervention.Totall 18 cases were improved after discharge.Another 3 cases died,including 2 cases died for postoperative multiple organ failure or disseminated intravascular coagulation,1 case died for hemorrhagic shock caused by still continue bleeding after surgery.The postoperative follow-up was performed during 3-18 months with the average of (10.81 ± 2.62) months.The fractures in all the surviving cases achieved bone healing with good function.Conclusion The emergency interventional arterial embolization combined with percutaneous minimally invasive screw fixation is a safe,fast and effective method for the treatment of pelvic fractures and hemorrhagic shock with less complications.

RESUMO
Objective To introduce a new management for ulcerative colitis. Methods There were eighteen patients underwent inferior mesenteric artery drug infusion who suffered from ulcerative colitis and cannot be cured by internal medicine. We observed the clinical symptoms and laboratory test results at the most resent follow up. Results All the patients’symptoms such as bellyache ,phrexia, abdominal distension were disappeared after interventional therapy. Diarrhea in seventeen patients was stopped. Fifteen patients who had blood stool were be cured. Erythrocyte and leucocyte were no longer be seen with stool laboratory test after drug infusion.Conclusion Inferior mesenteric artery drug infusion is another positively efficacy way for ulcerative colitis.
