ABSTRACT
Objective To explore the endovascular therapeutic strategy for multiple occlusive lesions of aorta and iliac-femoral arteries, and to discuss the technical skill as well as the clinical significance. Methods A total of 8 patients with multiple occlusive lesions of aorta and iliac-femoral arteries were enrolled in this study. Preoperative CT angiography and MR angiography were performed in all the 8 patients. The lesions included complete occlusion of abdominal aorta below renal artery level (n = 2), distal abdominal aorta occlusion (n = 4), distal abdominal aorta stenosis (n = 1), distal abdominal aorta membranous occlusion (n = 1), and diseased iliac artery (n = 12), external iliac artery (n = 8), femoral artery (n = 1) and popliteal artery (n = 2). Endovascular interventional management, including opening channel, thrombolysis, balloon dilation, stent implantation, etc. was carried out via different routes. The results were analyzed. Results After endovascular interventional management the abdominal aorta was completely reopened in all the 8 patients. Of 12 diseased iliac arteries, 9 were successfully reopened by interventional treatment and the remaining 3 were not treated. All the diseased external iliac arteries were opened up. The involved femoral artery and popliteal arteries were not treated. The patients were followed up for 1 -12 months. During the follow-up period, ischemic symptoms of the lower limb disappeared in 5 patients and were obviously improved in 2 patients. Recurrence of thrombotic occlusion was observed in one case, which returned to normal after transcatheter thrombolysis therapy. Conclusion For the treatment of multiple occlusive lesions of aorta and iliac-femoral arteries, endovascular interventional management is safe, simple and effective with fewer complications. The ischemic symptoms of the lower limb can be significantly improved.
ABSTRACT
Objective To explore the clinical value of the interventional and comprehensive treatment of iliac-femoral venous thrombus(I-FVT).Methods 32 patients with I-FVT were underwent interventional therapy.First the filter was implanted into the inferior vena caval via opposite side of femoral vein,then the catheteres were implanted into the pathologic regions within the vena to process the emboluses,and balloon-directed extend when necessary.Results The procedure of treatment was successful in all patients.The iliac-femoral veins were patent,swollen and pain symptom of lower limb disappeared gradually after operation.The followed-up study the longest period for 30 months showed no severe complications and recurrence.Conclusion The interventional and comprehensive therapy is of ideal effect on treating I-FVT,occuring interventional and comprehensive treatment has ideally effect to cure the patients with I-FVT.
ABSTRACT
Objective To evaluate the value of transcatheter arterial embolization(TAE) in the treatment of intractable epistaxis.Methods TAE using gelform or polyvinyl alcohol(PVA) particles of forty-one patients with intractable epistaxis were undertaken by the femoral artery approach,through selective catheterization of involved maxillary artery or the bleeding arteries for the stopage of bleeding..Results Of the forty-one patient,39 cases were cured by once TAE and the other 2 with recurrent bleeding on the next day after the TAE,to whom a second interventional treatment fullfilled the requirement.Conclusions Transcatheter arterial embolization is a simple,safe and effective treatment for the intractable epistaxis.
