Methods : Fifteen cases with cesarean scar pregnancy performed with uterine artery interventional therapy were retrospectively analyzed from July, 2006 to December, 2007 in our hospital. Results : All cases were treated successfully by uterine artery chemotherapy and embolism. All cases were embolized with gelatin sponge after chemotherapy, and eight with spring ring additionally. Vaginal bleedings were stopped after uterine artery embolization. Gestation sacculi deflated obviously. Serum human chorionic gonadotrophin descended dramatically. There was no severe vaginal bleeding by curettage after interventional therapy. The villi, decidua, or placental tissues were observed with degeneration and necrosis by pathology. Conclusion : Uterine artery chemotherapy and embolization was proved to be a safe and useful procedure for preventing and controlling vaginal bleeding, diminishing the risk of curettage and avoiding the loss of uterus.
Early endovascular interventional therapy can effectively improve the prognosis of patients with acute ischemic stroke. Dual-source CT dual-energy scanning, as a new CT imaging technology developed rapidly in recent years, with its unique technical characteristics and advantages, shows potential and application prospects in early endovascular interventional therapy of acute ischemic stroke. This article discusses the value of dual-source CT dual-energy scanning in the early screening and evaluation, the identification of postoperative iodine contrast agent extravasation and secondary cerebral hemorrhage, and the prediction of prognosis of patients with early endovascular interventional treatment of acute ischemic stroke. The purpose is to provide a theoretical basis for better application of dual-source CT dual-energy scanning in early endovascular interventional treatment of acute ischemic stroke.
ObjectiveTo investigate treatment methods and effect of endovascular interventional therapy for visceral artery aneurysms.MethodsThe clinical data of 32 patients with visceral artery aneurysms, who were treated in the No. 960 Hospital of PLA from February 2011 to April 2018, were retrospectively analyzed. It was proveded by the CT or digital subtraction angiography before the interventional therapy. The implantation of covered stent, coil embolization together with stent implantation, double stents placement or pure coil embolization were performed. The postoperative antithrombotic therapy was adopted in the patients accepted the stent implantation. The CT angiography was performed on the month of 1, 6, 12, 24 or the patient was uncomfortable after the treatment to evaluate the obstruction condition of the aneurysms, stent blood flow, and branches arteries, etc..ResultsThe success rate of the endovascular interventional therapy was 100%. In the 11 patients underwent the implantation of covered stent, the postoperative angiography showed that the stent lumen was patent and the aneurysm was not visualized. In the 9 patients underwent the coil embolization together with stent implantation and 3 patients underwent the double stents placement, the postoperative angiography results of the aneurysm showed that it was faintly visualized and the branch arteries were not involved. In the 9 patients underwent the pure coil embolization, the postoperative angiography showed that the aneurysm was not visualized. No perioperative mortality or procedure related complications occurred. No case was lost during the follow-up of a median period of 25.5 (6–48) months. During the follow-up, one patient developed the mild abdominal pain in one month, which disappeared after the symptomatic medication management. Except for 1 patient developed the mild stent stenosis (<30%) on the 12th month after the procedure, the stent and the branch arteries of the other patients were completely patent, and no aneurysms recurred.ConclusionFor treatment of visceral artery aneurysms, endovascular interventional therapy is safe and effective and shows an excellent short-term and mid-term effects.
In recent years, the number of interventions for valvular heart disease has been increasing day by day, and it has become a hot topic in the field of cardiovascular surgery. Given the aging global population and trends in the prevalence of valvular disease and the broadening of indications for transcatheter aortic valve replacement (TAVR), a breakthrough of 130000 TAVR procedures is expected by 2026. In the new technology development period, the development potential and technical advantages of heart valve interventional therapy should be faced squarely. This paper focuses on key issues such as comparison of outcomes after TAVR versus surgical aortic valve replacement (SAVR), prosthetic valve endocarditis after TAVR, and broadening of indications for TAVR, as well as recommendations on how surgeons face the era of TAVR. We hope that this article will help and attract the attention of cardiac surgeons.
ObjectiveTo evaluate the occupational exposures and protective condition of medical staff in operating room for interventional therapy. MethodsFrom September to November in 2014, 46 medical staff in the operating room for interventional therapy were adopted to complete the occupational exposures and protection situation survey. After that, we analyzed and scored all the questionnaires. ResultsThe awareness of the medical staff about occupational exposures and occupational protection in the operating room was low; the awareness rates of doctors, nurses, and radiology technicians were 74.2%, 63.0% and 66.7%, respectively. The general condition of implement of occupational protection measures of the medical staff was bad, and the average rate of the doctors, nurses and radiology technicians was 51.3%, 43.9%, and 15.2%. ConclusionThe implement rates of occupational protection measures of the medical staff in Operating Room for interventional therapy differ much from the awareness rates. The rates in doctors and nurses are higher than that in radiology technicians. We should strengthen the education of radiation damage and protection measures in doctors, and enhance the training of iatrogenic injuries related knowledge in clinical radiology technicians to reduce occupational hazards.
Transcatheter pulmonary valve replacement (TPVR) has transitioned from an experimental technique to a standard of care over the last 10 years, with its application expanding from conduit-based right ventricular outflow tracts (RVOTs) to complex native or patch-repaired anatomies. Valve systems like Melody, Sapien, and Harmony have shown favorable safety and efficacy, achieving a 10-year freedom from reintervention of 60% (95%CI 55%-65%) and freedom from valve dysfunction of 53% (95%CI 47%-59%). For severely dilated RVOTs, innovations like the Alterra adaptive stent and physician-modified endografts offer new solutions. Patient selection is now a comprehensive process, evaluating RV function, coronary compression risk, and anatomy. Standardized perioperative management has markedly lowered major complication rates. Advanced technologies such as 3D printing, finite element analysis, and virtual reality are paving the way for precision medicine in TPVR. For pediatric patients, prospective technologies like growable valves and fetal interventions represent new frontiers. With maturing technology and broadening indications, TPVR is progressively extending to younger patients, underscoring the importance of multidisciplinary teams and long-term follow-up for safety. This review systematically outlines the technological evolution, current status, and future trajectory of TPVR.

With the continuous development of interventional technology and devices, cutting-edge ideas and viewpoints are constantly discussed. This review summarized the development of intervention techniques and devices, hoping to provide some experience for the further development of transcatheter interventions for congenial heart disease.
ObjectiveTo investigate the efficacy of subclavian-carotid transposition (SCT) in treating patients with proximal subclavian artery occlusive diseases who were unable to be intervened, such as failure of intervention, congenital malformation and unwillingness to intervention.MethodsA retrospective review of 19 patients with proximal subclavian artery occlusion who underwent SCT from May 2016 to December 2018 was done. There were 14 males and 5 females with an average age of 54.05±17.34 years. The advantages and disadvantages of SCT in the treatment of proximal subclavian artery occlusion were analyzed.ResultsAll patients achieved immediate remission of symptoms after surgery. The stenosis degree of the proximal subclavian artery decreased from 100.0%±0.0% to 12.7%±10.1% after surgery. The average blood pressure difference between the unaffected side and the affected side decreased from 11.95±10.60 mm Hg to 0.89±5.75 mm Hg (P<0.01). Peripheral nerve injury occurred in 7 (36.8%) patients. The in-patient cost of subclavian artery occlusion patients who received subclavian artery interventional therapy in our hospital during the corresponding period was 3 392.12 yuan higher than that of the SCT group in average (if eliminating the patients whose cost was far from the average value, the cost of interventional therapy was 4 812.01 yuan higher than that of the SCT group in average). During 1-3 years' follow-up, 6 patients with neurological complication relieved. One- and three-year patency rates were 100.0%. No perioperative stroke, death or re-operation happened.ConclusionSCT is an ideal process for the patients with subclavian artery occlusion who cannot accept subclavian artery interventional therapy.
ObjectiveTo investigate the effectiveness and safety of esophageal ultrasound-guided percutaneous femoral artery closure of ventricular septal defect (VSD).MethodsThe clinical data of 24 patients with congenital VSD in our hospital from March 2017 to December 2019 were retrospectively analyzed, including 6 males and 18 females, with a median age of 12 (3-42) years, weight of 32 (12-91) kg, and VSD diameter of 4 (3-7) mm. There were 3 patients with VSD combined with atrial septal defect.ResultsTwenty-four patients successfully underwent interventional closure of percutaneous femoral artery under esophageal ultrasound guidance, and the position and shape of the occluders were good. The operation time was 45 (39-54) min, and the waist size of the occluders was 7 (5-12) mm. Among the patients, 14 patients used symmetric ventricular occlusion devices, 8 patients used asymmetric ventricular occlusion devices, and 2 patients used ventricular occlusion muscle occluders. Small amount of residual shunt occurred in 2 patients after the operation and it disappeared 3 months after the operation. One patient with right bundle branch block, which disappeared after 1 week of observation. There were no complications such as occluder closure, pericardial effusion or valve regurgitation during the perioperative period. During the follow-up period [3-18 (9.25±5.04) months], no serious complication occurred.ConclusionTransesophageal ultrasound-guided transfemoral artery occlusion for VSD is simple and safe, and it avoids the damage of radiation and contrast medium. It has advantages over traditional percutaneous interventional occlusion therapy.
ObjectiveTo investigate the clinical efficacy and application value of percutaneous interventional treatment for structural heart diseases under guidance of ultrasound.MethodsThe clinical data of 1 010 patients with structural heart diseases treated by transcutaneous ultrasound-guided occlusion in our hospital from December 2, 2015 to December 31, 2019 were retrospectively reviewed, including 360 males and 650 females, aged 1-50 years. There were 692 patients of atrial septal defect (603 with central type, 9 combined with arterial catheter, 80 with ethmoid type), 116 patent foramen ovale, 25 ventricular septal defects (3 combined with atrial septal defect), 132 patent ductus arteriosus, 32 pulmonary valve stenosis (3 combined with atrial defect), 1 main pulmonary artery window, and 3 aneurysm rupture of aortic sinus. All patients were diagnosed by transthoracic echocardiography (TTE) before operation. Treatment was accomplished intraoperatively through TTE or transesophageal echocardiography (TEE) via the femoral artery or femoral vein. After operation, echocardiography, electrocardiogram and chest radiograph were reexamined.ResultsSatisfactory results were obtained in 1 005 patients, and 1 patient failed to seal the ventricular defect and was repaired under direct vision, occluder detachment occurred in 5 patients after operation (3 patients of atrial septal defects underwent thoracotomy for Amplatzer device and were repaired, 1 patient of atrial septal defects was closed after removing Amplatzer device, 1 patient of patent ductus arteriosus underwent thoracotomy for Amplatzer device and was sutured), mild pulmonary valve regurgitation occurred after balloon dilation in 2 patients with pulmonary stenosis, a small amount of residual shunt was found in 2 patients with ventricular defect, which disappeared after 3 months of follow-up, and 1 patient of right bundle branch block occurred and disappeared after 1 week. After follow-up of 1-24 months, 3 patients of ethmoidal atrial septal defect were reexamined with mild shunt. The occluder was in good position and the pressure difference of pulmonary valve was significantly reduced. There was no complication such as hemolysis, arrhythmia, embolism or rupture of chordae tendinae.ConclusionPercutaneous transfemoral artery and vein guided by TTE or TEE is safe and effective, with little trauma, no radiation or contrast agent damage, and has significant clinical efficacy and application values.
