ObjectiveTo summarize the applied research status on the evaluation tools of patient-reported outcome at home and abroad in patients with venous thromboembolism (VTE). MethodBy searching and analyzing the literatures, this paper summarized the concept, evaluation tools and application status of patient-reported outcome in the field of VTE. ResultsThe patient-reported outcomes can more comprehensively and accurately evaluate the disease burden and treatment effect of patients with venous thromboembolism, and can help doctors better understand patients' needs and guide individualized treatment and rehabilitation plans. ConclusionsPatient-reported outcome has a broad application prospect in the field of venous thromboembolism. Further promotion and application of patient-reported outcome can promote the development of medical research and provide reference guidelines for improving the management of patients with venous thromboembolism.

Objective To discuss feasibility and effectivity of intraoperative ultrasound (US) during endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm. Methods A radiographic contrast nephropathy patient of abdominal aortic aneurysm and left internal iliac artery aneurysm was treated by EVAR without iodine contrast media assisted by US. Then summarized the data of this patient. Results The precise placement of the stent-graft was performed for abdominal aortic aneurysm. The left internal iliac artery aneurysm was successfully treatment with the stent-graft and coils. Intraoperative Ⅱ type endoleak from inferior mesenteric artery and Ⅰ b type endoleak from right iliac stent were identified by using US. The operative duration was 120 min and the blood loss was only 20 mL. Ⅱ type endoleak was still detected and the Ⅰ b type of endoleak was loss on postoperative a week. Conclusion Intraoperative US-assisted EVAR in patients with infrarenal abdominal aortic aneurysm represents a new option for intraoperative visualization of aortoiliac segments required as proximal or distal fixation zones and identification of endoleaks, especially in those patients with contraindications for usage of iodine-containing contrast agents.
ObjectiveTo analyze the main points and advantages of covered endovascular reconstruction of aortic bifurcation (CERAB) technique in the treatment of complex aortic and iliac artery lesions. MethodThe data of the patient with bilateral common iliac artery stenosis and lower abdominal aortic calcification treated by CERAB technology in the Department of Vascular Surgery of West China Hospital of Sichuan University and the technology in combination with the characteristics of balloon-expandable covered stent were analyzed. ResultsThe lesions were successfully treated by CERAB technique. The stents of bilateral iliac arteries were in perfect shape and good adherence. The radiography of the abdominal aorta and bilateral internal and external iliac arteries were well displayed. ConclusionsFrom analysis results of this case, CERAB technology is effective and feasible in treatment of lesions at the bifurcation of the main aortic and iliac artery. The shape of aortic bifurcation is satisfactorily recovered. The key point for the successful implementation of this technology is balloon-expandable covered stent.
Objective To investigate the technical feasibility and effectiveness of intraoperative sac embolizaion with coils and fibrin glue for preventing type Ⅱ endoleak after endovascular aneurysm repair (EVAR). Methods A patient with abdominal aortic aneurysm (AAA), which had high risk of type Ⅱ endoleaks, was treated with combined packing of coils and fibrin glue in order to prevent type Ⅱ endoleak after EVAR. Percutaneous catheter preset and balloon occlusion were used to ensure accurate packing. Results At the end of the operation, the angiography showed that the blood flow of the stent and distal artery was unobstructed, there was no type Ⅰ and Ⅲ endoleaks, and delayed angiogram showed no collateral circulation of aneurysm. The procedure was successful. The operative duration was 120 min and the blood loss was only 20 mL. No complications such as colonic ischemia and ectopic embolism occurred, and the patient was discharged on 3 days after operation. At 6 months after follow-up, the computerized topographic angiography showed that the aneurysm cavity was completely thrombotic, without type II endoleak, and the diameter and volume of aneurysm were reduced. Conclusions The technique of intraoperative sac embolizaion with coils and fibrin glue during EVAR is safe and effective to prevent postoperative endoleaks, which is simple and feasibility. Intraoperative indwelling catheter and balloon blocking are the key points of successful implementation of this technique.
ObjectiveReporting a case of hybrid procedure of extensive thoracoabdominal aortic aneurysm (TAAA) with type B dissection due to Marfan syndrome (MFS) using a prosthetic graft as the distal landing zone for stent-graft.MethodsRetrospectively summarize in-hospital profiles of a patient for who was diagnosed as MFS complicated with TAAA and type B dissection and admmited to Vascular Surgery Department of West China Hospital in May 2018. A GORE-TEX 18 mm×9 mm Y-shaped graft was sewn side-to-end to the bifurcation of left common iliac artery as the inflow site, and a self-made penta-limb graft was sewn side-to-end to the bifurcation of the 18 mm graft. The visceral and bilateral iliac arteries were reconstructed subsequently. Then, the release of the stent-graft was designed from distal to proximal. The distal part of the stent-graft was anchored into the main body of the 18 mm Y-shaped graft.ResultsThe patient underwent the operation successfully with a duaration of 6 h, blood loss of about 800 mL. No serious postoperative complications occurred. Computed tomography angiography at 2-year follow-up showed that the bypass grafts were patent without endoleak, stent migration, stent infolding or infections of the vessel graft and endograft.ConclusionThis modified management of the landing zone could be a proper choice for this kind of rare case as extensive aneurysm or dissection involved in patients with MFS.
ObjectiveTo explore the ultrasonic morphological indexes influencing the effectiveness of ultrasound-guided thrombin injection (UGTI) in the treatment of iatrogenic femoral artey pseudoaneury (IFAP).MethodsThe patients with IFAP treated by UGTI in the West China Hospital of Sichuan University from 2015 to 2017 were collected according to the inclusion criteria. The demographic data, comorbidities, clinical symptoms, ultrasonic morphological parameters, thrombin dosage, and postoperative complications were analyzed. The risk factors of technical success of UGTI were analyzed by logistic regression analysis. The technical success was defined as absence of flow within the FAP immediately after UGTI. ResultsA total of 53 patients who met the criteria of inclusion were included in this study. The technical and treatment success rates of UGTI were 84.9% (45/53) and 96.2% (51/53), respectively. No deep venous thrombosis, arterial thromboembolism, infection, bleeding, allergy, and other complications or death occurred in all patients. There were no statistical differences in the age, clinical symptoms, comorbidities (except hypertension, P=0.040), ultrasonic morphological parameters (except femoral artery diameter, P<0.001), and thrombin dosage between the patients with technical success and failure (P>0.05). Multivariate logistic regression analysis showed that the smaller femoral artery diameter was the risk factor of the technical failure [OR=0.350, 95%CI (0.165, 0.743), P=0.006]. Further adjustment of thebaseline data of patients (excluding patients with hypertension), the logistic regression analysis still found that smaller femoral artery diameter was the risk factor of the technical failure [OR=0.419, 95%CI (0.205, 0.860), P=0.018].ConclusionsUGTI in treatment of IFAP is minimally invasive and has a higher technical success rate. Smaller femoral artery diameter might affect technical success rate of UGTI.
