1.Interventional treatment of infrapopliteal arteriosclerosis occlusive disease: latest clinical progresses
Journal of Interventional Radiology 2017;26(2):188-192
The infrapopliteal arteriosclerosis occlusive disease mainly involves the anterior tibial artery,posterior tibial artery and fibular artery.For the arteriosclerosis occlusive disease of larger arteries of lower extremity,such as iliac artery,femoral artery,etc.,the interventional therapy pattern has been already very mature.However,as the infrapopliteal artery is fine in diameter and the lesion is usually wide with extensive calcification,it is hard to effectively treat the infrapopliteal arteriosclerosis occlusive disease with routine interventional therapy.The therapeutic methods of infrapopliteal arteriosclerosis occlusive disease mainly include surgical treatment,endovascular treatment,drug therapy,and the autologous stem cell transplantation therapy that is still in the research stage at present.This paper aims to introduce the latest progress in interventional therapy for the treatment of infrapopliteal arteriosclerosis occlusive disease in recent years,and to make a prospect for clinical practice in future.

Objective To evaluate the efficacy of superselective renal artery embolization in the treatment of iatrogenic renal hemorrhage. Methods The clinical data of 31 iatrogenic renal hemorrhage patients who had underwent superselective renal artery embolization were retrospectively analyzed. Results All patients were found to have bleeding site by contrast examination, including pseudoaneurysm in 21 cases, renal arteriovenous fistula in 3 cases, extravasation of contrast media in 4 cases, and pseudoaneurysm and renal arteriovenous fistula in 3 cases. Microcoil embolization was used in 20 patients, and microcoil embolization combined with gelatin sponge was used in 12 patients. Thirty patients got successful embolization once, and success rate was 96.8%(30/31). One patient got successful embolization in the second time. There were no serious complications and no recurrence of renal hemorrhage. Conclusions Superselective renal artery embolization in the treatment of iatrogenic renal hemorrhage has the advantages of exact hemostasis, less trauma and fewer complication, and can retain the normal renal tissue maximumly.

Objective To investigate the value of MR imaging in detecting occult fractures. Methods Sixteen cases with acute trauma were studied using radiography and MR imaging, three cases also underwent CT examinations. Three fractures occurred in the femur condyle, 8 in the proximal tibia and 5 in the thoracolumbar spine. Results All sixteen cases had normal radiographic results. In 11 cases with femur condyle and tibia occult fracture, MR imaging demonstrated linear low signal in the subcortical region in 3 cases and irregular low signal from articular faces to shaft in 8 cases on both T 1WI and T 2WI, and high signal changes around low signal were seen on T 2WI, and the width of low signal was less than 4 mm on both T 1WI and T 2WI. The high signal in T 1 weighted-Fat saturated sequence was more remarkable and wider than that on T 2WI. 3 cases with CT scanning showed no fracture signs. In five cases with thoracolumbar vertebral occlut fractures, MR imaging demonstrated horizontal linear low signal in the center of vertebra on both T 1WI and T 2WI, and high signal changes around low signal were seen on T 2WI. Conclusions MR imaging could early determine the diagnosis of occult fractures. MRI should be the next examination of choice when plain films fail to reveal suspected fractures in the setting of suggestive symptoms and positive physical examination.
