무명정맥에서 상대정맥으로 이탈된 자가팽창형 stent의 경피적 제거
구동억 순천향의학연구소 2004 Journal of Soonchunhyang Medical Science Vol.10 No.2
Self expandable stents are being used increasingly in conjunction with balloon dilatation for trearment of innominate vein stenosis. Stent misplacement or migration is a complication of the procedure, and may be symptomatic and warrant repositioning or removal. We report the case of a patient whose innominate vein stenosis was managed with self expandable stent and was complicated by embolization of stent into the superior vena cava. This report illustrates percutaneous endovascular removal of a migrated stent from the superior vena cava using a Goose neck snare

Endovascular procedures are becoming the standard type of care for the management of hemodialysis vascular access dysfunction. As with any type of medical procedure, these techniques can result in procedure-related complications, although the expected number of complications is low. The clinical extent of these complications varies from case to case. Management of these cases depends on the clinical presentation. Major complications such as vein rupture, arterial embolism, remote site bleeding or hematoma, symptomatic pulmonary embolism and puncture site complications necessitating treatment require major therapy. Minor complications such as non-flow compromising small puncture site hematoma or pseudoaneurysms require little or no therapy. It is essential that the interventionist be prepared to manage these complications appropriately when they arise.

Arteriovenous malformations (AVMs) are characterized by the presence of abnormal connections between feeding arteries and draining veins. It is generally assumed that symptomatic lesions can preferably be treated. Due to high arterial blood flow, there is a risk of bleeding with surgical excision alone, which can be massive and life threatening during the operation. According to recent advances in interventional technique, a hybrid approach using embolization of the feeding artery with subsequent immediate excision of the AVM for successful management of vascular lesions could be applied to AVMs. Herein, we describe a case of successful excision of AVM in the left soleus muscle using a hybrid approach.

It may be difficult to differentiate renal cell carcinoma involving collecting system from renal pelvis urothelial tumor invading into renal parenchyma. The purpose of this study was to find out CT differential points of two diseases. 15 cases suggested invasion into other compartment in CT images were selected and evaluated about the presence or absence of hydronephrosis, CT renal function, renal contour changes due to mass and tentative diagnosis. Renal cell carcinoma was characterized by no hydronephrosis(80%), normal CT renal function (100%) and outward bulging mass(100%). However, renal pelvis urothelial tumor showed hydronephrosis(70%), abnormal CT renal function(60%) and preserved reniform shape(100%). In conclusion, renal contour changes and CT renal function are reliable criteria in differentiating two diseases.
Selective Uterine Artery Embolization for Management of Interstitial Ectopic Pregnancy
양승부,Sang Jin Lee,Hwan Sung Joe,Dong Erk Goo,Yun Woo Chang,김동훈 대한영상의학회 2007 Korean Journal of Radiology Vol.8 No.2
Interstitial ectopic pregnancy is a rare condition of pregnancy and may be very dangerous if not identified and treated urgently. We report a case of successful treatment of an interstitial pregnancy using selective uterine artery embolization. A 27-year-old woman with interstitial pregnancy was treated by uterine artery embolization after failure of systemic methotrexate treatment. Her serum betahuman chorionic gonadotropin ( -hCG) was undetectable one month after the therapeutic embolization and transvaginal sonography 31 days after embolization showed normal endometrium and cornu. The patient achieved a normal pregnancy eight months after embolization.
