Aortic dissection is clinically suspected from the typical symptoms and signs and may be confirmed by computed tomography or aortography. But atypical presentations can be seen in a minority of cases, such as SVC syndrome, right pulmonary artery stenosis etc. We present a case which was initially suspected to be a right atrial tumor because of a large filling defect in the right atrium on radionuclide angiocardiography but finally confirmed to be dissection of ascending aorta by computed tomography.

We successfully closed the isolated patent ductusarteriosus(PDA) in 2 female patients using the Rashkind Double-Disc Occlusion system. nonsurgical closure of PDA usin plug was introduced by Porstmann in 1968 through transfemoral artery catheter and using umbrella by Rashkind in 1977 througth venous site. There has been continued improvement and simplification of the equipment as well as in the implantation technique. Nowaday, a multicenter study was conducted to test the safety and effectiveness of this interventioal method in States. Successful closure rate was high but some problems were reported such as embolization, abnormal deployment and residual shunt. Residual shunt was visualized by aortography in our both cases immediately after intervention but continuous murmur could not be heard in both cases. Oxygen step-up disappeared immediately after occluder implantation in both cases. Complete occlusion was expected with thrombus in near future.

Pulmonary sequestration is a rare congenital mass of nonfunctional pulmonary tissue that lacks of a normal connection with the bronchial tree or pulmonary artery. It may be clinically asymptomatic but may be complicated by recurrent infection. The classical therapeutic approach is to resect the sequestration lobe to prevent infection. The arterial embolization of feeding artery is a new technique and a less invasive treatment than conventional surgical removal. We reviewed two patients with pulmonary sequestration whose complaints were persistent fever and cough or hemoptysis. They were diagnosed by computed tomography and aortography and treated with embolization of feeding arteries. They were sucessfully treated without any complication. We report two cases of pulmonary sequestration treated with arterial embolization instead of surgery.

Abdonimal aortography and histopathologic examinatio after absolute ethanol infusion at ast (0.4cc/sec) andslow speed (0.04cc/sec) were performed on 16 rats(2 controls, 7 fast infusion groaup, 7 slow infusion group).Angiographic and histopathologic findings were correlated and the findings of slow and fast infusion groups werestudied. The rsults are as follows: 1.Histopathologic findings of the fast infusion group revealed wide area ofglomerular and tubular collapes, obliteration of the free space between the Bowmann's capsule and golmerulus,sloughing and loss of the endothelium, fresh thormbi attached to the wall, and cleavage of the muscle layer of thearteries. 2. Angiographic findings of the fast infusion group revealed luminal irregularity, early ostruction ofthe aorta and the renal arteries,and delayed circulation time. 3. Histopathologic findings of the slow infusiongroup revealed degenerated, coalesced red blood cell packed in the glomeruli, focal areas of severe glomerular andtubular damage on relatively normal backgroun, endothelial and muscular damage of the arteries. 4. Angiographicfindings of the slow infusion group revealed focal perfusion defect of the kidney, delayed circulation time, andmild luminal irregularity, but there was no obstruction of the major arteries. 5. In conclusion, author believesthat endothelial damage and thrombus formation from the damaged vessel wall, as well as direct cytotoxicity and insitu emboli fommation play a significant role in the embolic effect of absolute ethanol.

Traumatic thoracic aortic injury is typically fatal. However, recent improvements in pre-hospital care and diagnostic modalities have resulted in an increased number of patients with traumatic aortic injury arriving alive at the hospital. Also, the morbidity and mortality associated with endovascular repair are significantly lower than with conventional open surgery in traumatic thoracic aorta injury. We experienced two cases of successful management of traumatic thoracic aortic dissection with endovascular stents caused by traffic accidents.

Pulmonary sequestration is a very rare congenital malformation in which a mass of pulmonary tissue is detached from the normal lung and receives its blood supply from a systemic artery. It may be clinically asymptomatic or it has a wide spectrum of various clinical manifestations. The clinical therapeutic approach is to resect the sequestered lobe to prevent frequent complication such as infection. The arterial embolization of feeding artery is a new technique and a less invasive treatment than conventional surgical removal. We have experienced a 17- year-old male with pulmonary sequestration whose complaints were pain in left lower chest. He was diagnosed by computed tomography and aortography and successfully treated with embolization of feeding artery. We report a case of pulmonary sequestration treated with arterial embolization instead of surgery.

We report a case of coronary arteriovenous fistula in a female adult confirmed by aortography. The fistulous communication was between right coronary artery and right ventricle. This is the first case report of adult patient with coronary arteriovenous fistula in Korea.

With the increasing application of endovascular stent-graft in the treatment of aortic dissection, there are still some problems and controversies in the selection of the stent-graft oversizing. This review summarized the latest research in the study of the baseline and measurement in stent-graft oversizing selection, the relationship between stent-graft oversizing and prognosis and the selection of stent-graft oversizing in different patients with different conditions, providing a reference for the endovascular stent-graft oversizing selection in the treatment of aortic dissection.
