바스켓을 이용한 동맥내 카테터 잔유물의 경피 경혈관 제거:1예 보고
전의용 대한영상의학회 1995 대한영상의학회지 Vol.32 No.4
Popular use of intravascular catheterization of both diagnostic and therapeutic purposes led to increase iniatrogenic intravascular foreign bidues for which percutaneous removal has been accepted as the treatment ofchoice. The majority of percutaneously removed intravascular foreign bodies are located in the right side of theheart, large veins, and pulmonary arteries and intraarterial foreign body is rare. We recently experienced a caseof intraarterial fragmented catheter which was removed with a basket percutaneously without any complication.
강직성 척추염에 의한 천장골염의 자기공명영상 소견: MPGR영상과 조영 증강후 지연 T1강조영상의 역할
전의용 대한영상의학회 1997 대한영상의학회지 Vol.37 No.4
Purpose : For early diagnosis of sacroiliitis in spondyloarthropathy, the MRI findings of sacroiliitis, roles of MPGR(Multiplanar Gradient Recalled Acquisition in Steady State), and delayed post-contrast T1-weighted images were evaluated.Materials and MEthods : Twenty six patients with seronegative spondyloarthropathy (probable clinical diagnosis of ankylosing spondylitis) were grouped as either less than radiographic grade Ievaluated in every patient, and predominat sites were determined. The two groups were then compared. In 17 patients, the number of enhancing panni seen on early and delayed post-contrast T1-weighted images was counted and compared between the two grupus.Results : Panni were found in all cases, and in both groups, predominant patterns of involvement were the lower and iliac aspects of the sacroiliac joints in both groups;in group A, the synovial joints and punctate pannus were predomimantly involved, and in group B, the ligamentous joints as well as the synovial joints and linear pannus. In group B, more periarticular fat accumulation than periarticular osteitis was found. For the evaluation of changes in joint space, MPGR images were superior to spin echo images. For the delineation of enhancing pannus less than radiographic grade I, delayed post-contrast images were statistically superior to those which were early post-contrast.Conclusion : MRI can detect early sacroiliitic change according to the predominant sites of involvement, and delayed post-contrast images play a role in the diagnosis of early sacroiliitis. MPGR imaging is good for the evaluation of joint space change.

Object : To evaluate changes in the diameter of bronchi and pulmonary arteries during respiration. Materialsand Methods : The ratio of the diameter of matched inner bronchi and accompanying pulmonary arteries wascalculated from full inspiration and expiration HRCT of healthy men. Results : In 106 pairs of matched bronchi andpulmonary arteries, the brohchial-arterial ratios were 0.61$\pm$0.18(upper lung), 0.72$\pm$0.21(lower lung), and0.65$\pm$0.20(total) at full inspiration and 0.51$\pm$0.32(upper lung), 0.52$\pm$0.15(lower lung), and 0.51$\pm$0.26(total) atfull expiration HRCT, denoting a statistically significant increase in bronchial diameter of the entire lung atfull inspiration. The inner diameter of the bronchus was larger than the diameter of the accompanying pulmonaryartery by 0.1% at full expiration and 8.5% at full inspiration. Conclusion : The result of this study would behelpful in understanding the physiology of the lung during respiration.
좌측 하폐엽에 공급하는 비정상적인 체동맥의 치료(수술과 색전술의 비교)

폐에 체동맥이 분포하는 선천성 기형은 드문 질환으로 하폐엽의 기저분절에 폐동맥 대신 대동맥에서 1개 이상의 체동맥이 나오는데 정상적인 기관지와 연결 유무에 따라 폐 분획증과 좌측 폐동맥 이상기시증(Anomalous Origin of Left Pulmonary Artery, AOLPA)으로 구분된다. 한일병원 흉부외과에서는 하행 흉부 대동맥에서 시작되는 비정상적인 체동맥을 가진 두 예의 폐동맥 기형을 경험하고, 1예는 기저분절절제술을, 다른 예는 동맥색전술을 시행하였고, 2년간 관찰한 결과 양호하였다. 이 결과를 바탕으로 외과적 수술이 이 기형의 근본적인 치료법이지만, 전신상태가 불량하거나 폐기능이 저하된 고위험군에서 동맥색전술도 선택적으로 시행할 수 있는 가능한 치료법으로 생각된다.

Purpose: To measure the length of the upper extremity vein between the elbow crease and the carina (elbow crease to carina length, ECL), to facilitate the appropriate positioning of the tip of the peripherally inserted central catheter (PICC). Materials and Methods: A total of 124 patients (64 men and 60 women; mean age 65.2 ± 15.4 years; range, 21-90 years) inserted with PICC through the right basilic vein under fluoroscopy were included in this retrospective study. The ECL was determined as follows: ECL = (distance from elbow crease to puncture site) + (the catheter length of PICC) - (distance from carina to catheter tip on post-procedural chest radiograph). We analyzed the relationship between ECL and patient height. Results: The mean ECL through right basilic vein was 42.07 ± 4.03 cm (27.5 to 52.2 cm). ECL was found to be significantly correlated with patient height: ECL (cm) = 0.24 × patient height (cm) + 3.75. Conclusion: The formula developed in our study would be helpful for predicting the optimal catheter length during a blind bedside procedure of PICC via the right basilic vein.

We report on three cases of longstanding pulmonary tuberculosis patients with coronary to bronchial artery fistula (CBF) who presented with recurrent massive hemoptysis. The first and second patients died because of decreased functional pulmonary volume plus massive hemoptysis and cannulation failure of CBF due to hypovolemic vasospasm, respectively. When recurrent hemoptysis occurs despite successful embolization treatment, CBF should be considered as a potential bleeding source. Moreover, a coronary angiography should be performed, especially in patients with longstanding cardiopulmonary disease such as pulmonary tuberculosis.

배영아,김현범,전의용,황희성,이인재,이열,배상훈 대한영상의학회 2006 대한영상의학회지 Vol.54 No.4
Cystic adventitial disease of the popliteal artery is rare condition, but it is an important cause of peripheral vascular insufficiency in young men. Conventional angiography or MR imaging has traditionally been considered as the study of choice to diagnose this disease. We experienced a case of cystic adventitial disease of the popliteal artery that was diagnosed by 16-slice MDCT angiography, and this imaging modality displayed an accurate diagnostic capability for this disease. 슬와동맥의 cystic adventitial disease는 드문 질환으로 젊은 남성의 말초 혈관 부전의 중요한 원인이다. 전통적으로 고식적 혈관조영술이나 MR영상이 영상진단의 표준이지만 저자들은 16-slice MDCT로 영상진단이 가능하였던 슬와동맥의 cystic adventitial disease를 경험하였기에 이를 보고하고자 한다.

Intractable hematuria in from pelvic malignancy can be managed with conservative treatment in most patients. However, when treatment fails, surgical intervention may be required. Unfortunately, in most cases, the general condition of most patients is unfavorable for major surgery, with many patients having an inoperable status. We present two cases where intractable hematuria was successfully controlled by bilateral embolization of the inferior vesical artery with polyvinyl alcohol particles. Hematuria did not recur during the subsequent period and no complication was observed. Thus, bilateral embolization of the inferior vesical artery should be considered as an alternative method for the treatment of massive intractable hematuria caused by pelvic malignancy.

Tuberculous pseudoaneurysms of the aorta are rare entities that have been reported as fatal complications requiring early diagnosis and treatment. Here, we describe a case of a tuberculous pseudoaneurysm of the descending thoracic aorta in a patient with miliary tuberculosis. The computed tomography findings of a tuberculous pseudoaneurysm and outcomes of treatment with endovascular stent graft are described. Tuberculous pseudoaneurysms of the descending thoracic aorta were treated with endovascular stent graft. However, perigraft recurrence of tuberculosis after cessation of antituberculous drugs led to surgical treatment.
