전석길 대한영상의학회 1976 대한영상의학회지 Vol.12 No.2

This study is comprised of analysis of 107 cases of bezoars, proved by upper G-Ⅰ series, endoscopic examination and surgical exploration, in Kyungpook National University Hospital, from January 1965 to May 1974. Results were as follows: 1) Male was more affected than female, as 64.5%(69 cases). 2) The peak age incidence was 5-19 year-old(43.8% : 47 cases). 3) Winter was peak seasonal incidence, 62.5% : 67 cases, which suggested a relationship between seasonal incidence and the time of harvest and ingest of persimmon and Diospyros lotus. 4) All 107 cases were phytobezoars and there was history of ingestion of persimmon and Diospyros lotus. 5) Bezoars after certain gastric operation(involving total or subtotal reasection) were 5 cases(4.7%) and within 2-3 years after the operation. 6) Gastric ulcerations associated with gastric bezoars were found in 10 cases. 7) Sites of bezoars were ileum (47 cases: 39.1%), stomach(35 cases: 30.0%) and jejunum (20 cases: 20.0%) as frequency. A d only 2 cases were found in the site as colon, but also found in small bowel loops in those cases. The latter suggested difficulty of passage of the bezoar beyond the ileocecal junction. 8) Single bezoar was more than multiple, as 87 cases to 20 cases. 9) Chief complaints or symptoms were abdominal pain (in epigastrium, whole addomen or periumbilical area), vomiting, palpable mass and melena, as frequency.

Authors want to report that PTA was an out-standing therapeutic method in treatment of renovascular hypertension by renal artery stenosis due to Takayasu's arteritis in an 18-years-old Korean female. Abdominal aortogram and bilateral renal arteriogram showed mild smooth narrowing of the mid abdominal aorta of 4cm length from origin of renal arteriogram showed mild smooth narrowing of the mid abdominal aorta of 4cm length from origin of renal arteries, complete occlusion of left renal artery from it's origin with a few small collateral arteries and severe stenosis of proximal right renal artery. PTA of right renal artery was performed with Gruntzig Balloon dilatation catheter, and the patient's blood pressure was down to 120/80 from 220/130, stable for 8 months follow-up examination. Takayasu's arteritis is one of the most important cause of renovasular hypertension in Orientals. Multiple treatment modalities, such as steroid administration or variable surgical intervention, were attempted and limited response was presented. But PTA is a simple, cost-effective, repeated, and relatively complication-free method in treatment of renovascular hypertension due to Takayasu's arteritis, with an outstanding result, as authors case.

Knowledge of the renal arterial and venous anatomy is an essential to the renal transplantation. Followings are the results from analysis of the renal artery and vein in 85 candiates of renal transplant dornor. 1. Bilateral single renal artery was 70.6%. 2. double renal artery was 18.8%, and single renal artery associated with accessory artery was 10.6%. 3. Extrarenal bifurcation of the single renal artery was 70.0%. 4. average length of the single renal artery was 40mm of right renal artery and 33mm of left renal artery. 5. level of the origins of both renal artery form abdominal aorta was as follows: Same level of both renal arteries was 50.0%, right renal artery was higher than left in 36.7%, and left was higher in 13.3%. 6. Bilateral single renal vein was observed in 84.7%, and remainder was double renal vein and 1 case of triple right renal veins. 7. Nut cracker phenomenon was observed in 22.6%. 8. Extrarenal confluence of lobar renal veins was 20%. 9. In 3 cases, nutcrac er phenomenon was associated with extrarenal confluence of lobar renal veins. 10. Inferior adrenal artery was not opacified in 36.5% of renal arteriogram

Morphologic analysis of the mitral valve is essential to evaluate mitral regurgitation and causes of mitral insufficiency. The cineangiographic left ventriculogram in right anterior oblique view of 100 Korean adults(62 male and 38 female) were analysed to determine the anatomy of the mitral valve. According to the position of the fulcrum and the configuration of the fornix of left ventricle, four types of mitral valve were identified. There was 52% type l. 12% type ll, type lll and 7% type IV. No significant difference in change of mean diameter between systole and diastole was noted among the 4 types of the mitral valve(23%). Visualization of the left ventricular internal structure revealed no significant differences between the various types. Because of the frequency in pseudoprolapse of mitral valve of the type 1 and 3, 2D echocardiographic and cineangiographic evaluation of mitral regurgitation should be carefully done in Koreans in which those types are more frequent than Caucasians.

Purpose: This study was designed to evaluate the usefulness of a technetium-99m mercaptoacetyltriglycine (Tc-99m MAG3) single photon emission computed tomography (SPECT) performed on transplanted kidney. Materials and Methods: Thirty renal transplant patients were included in this study. Planar scan was performed for 30 minutes using 555 MBq Tc-99m MAG3. A post-voiding SPECT scan was acquired on the third, seventh, fourteenth and twenty eighth day after transplantation. Results: SPECT scan showed interpretable image quality in 26 of 30 patients (86.7%) and 84 in 120 scans (70%). Fourteen of 26 patients with interpretable SPECT image showed decreased or increased radioactivity, but only 5 had abnormal findings on the planar scan. Focal SPECT defects were seen in allografts with normal function (n=3), acute tubular necrosis (n=3), and acute rejection (n=2). The defects are thought to reflect focally underperfused renal parenchyme or, in normal allografts, an artifact from uneven radioactivity distribution. Four of 10 patients with renal arterial variation showed focally decreased radioactivity and SPECT helped guide further studies that confirmed the exact cause. Five of 10 patients with acute tubular necrosis or acute rejection showed focally decreased radioactivity, but its relation to the patients' clinical course was not clear. Focally increased radioactivity was observed in 5 allografts with normal function and 1 with double ureter in which local clearance delay was observed. Conclusion: Tc-99m MAG3 SPECT renal scan can detect additional focal abnormalities compared to planar scan. Further study is necessary to elucidate the exact clinical significance of the SPECT findings.

전석길 대한영상의학회 1987 대한영상의학회지 Vol.23 No.1

The increasing use of the indwelling venous catheters and cardiovascular catheters has led to many iatrogenic complications. One of the most serious complications is catheter embolization, caused by inadvertent fracture of a fragment of catheter remaining within cardiovascular systems. In the catheter embolization, there are serious consequence such as thromboembolism, sepsis, cardiac arrythmia and others. Fisher and Ferreyro (1978) reported a 71% incidence of serious morbidity or death following to intravacular foreign bodies in patients without removal. The authors experienced a case of retained central venous pressure monitoring catheter fragment extending from superior vena cava to hepatic segment of inferior vena caba. CVP catheter was introduced into right subclavian venous route for hyperalimentation, because of poor general condition for operation of afferent loop syndrome following to resecton of the gastric carcinoma with Billoth II operation. On attempting to remova of CVP catheter on recovery from afferent loop syndrome, a large portion of the CVP catheter was cut off into S.V.C. Percutaneous puncture of right femoral vein with Seldinger technique was done and 9F introducer sheath was indwelled. The hellical baket of Dotter intravascular retriever set was advanced through sheath was indwelled. The hellical basket of Dotter intravascular retriever set was advanced through the sheath upto retained CVP catheter, and it was grapsed. The retrieved CVP catheter fragment showed several tiny blood clots on surface. The patientwas uneventfully recovered, and was discharged asymptomatic on second day of the procedure.
