1.Surgical Treatment of Spondylolysis: A Report of 7 Cases
The Journal of the Korean Orthopaedic Association 1970;5(3):127-132
Three main types of operative teehnique are in general use today in the treatment of spondylolysis or spondylolisthesis: namely, total laminectomy alone, total laminectomy and posterior fusion, and anterior interbody fusion. According to Hoover(1968), above operations have yielded satisfactory results in approximately 70% of the cases. In recent years, Watkins, Adkins and Rombold have independently reported their cxperience with posterolateral intertransverse fusion, which they claim is based on a more sound mechanical basis and has yielded better results. The author performed anterior interbody fusion in 4 cases and posterolateral intertransverse fusion in 3 cascs at Seoul Naval Hospital during the 2 year period from May 1968 through May 1970 The postoperative follow-up period was maximum one year and minimum six months. Only one casc of anterior interbody fusion has shown sound fusion, while all ihe three posterolateral intertransverse fusions with posterior H-graft have yielded sound fusion with satisfactory clinical improvement by six months after operation.

With 2mm-thick CT scanning during the rapid infusion of contrast material(TICT), cerebral aneurysms arising from the circle of Willis and adjacent vessels can be directly visualized. Twenty-five patients who had cerebral aneurysm confirmed by surgery were examined with TIGT and digital subtraction angiography. The authors examined TIGT prospectively to assess the detection rate of the cerebal aneurysms and to evaluate the clinical usefulness of TIGT. The detection rates of aneurysms by TIGT and digital subtraction angiography were 68% and 84%, respectively. TIGT is a rapid, safe and reliable method in the evaluation of patients with suspected cerebral aneurysm, permitting direct visualization of the aneurysm.

Journal of the Korean Radiological Society 1995;33(6):865-868
Arteriovenous mafformation(AVM) of female pelvic organ is a rare disease of unknown cause. The authors' report a case of pelvic AVM which was incidentally found during US examination of the patient with choriocarcinoma after chemotherapy. The real-time sonography revealed several cystic lesions around the uterus with adjacent dilated tortuous vessels. The color Doppler sonography depicted abundant blood flow mixed with red and blue colors within the cystic lesions and rapid turbulent systolic and diastolic flows. CT showed well-enhancing round vascular lesions with elongated vessels in the pelvis, and MRI depicted signal-void cystic lesions on both T1 and T2 weighted images with small portions of high intensity within the lesions on T2 weighted image. The angiography revealed pelvic AVM fed by tortuous uterine and vaginal arteries with a dilated draining vein

PURPOSE: Congenital Iobar agenesis of the liver is a rare anomaly. We report five cases (three cases of right Iobar agenesis and two cases of left Iobar agenesis) and discuss the radiologic findings of this congenital anomaly. MATERIALS AND METHODS: Between July, 1992 and February, 1993, three cases of right Iobar agenesis and two cases of left Iobar agenesis of the liver were diagnosed by means of computed tomography(CT) and/or sonography. MR imging was performed in two patients, cholangiography in two, and digital subtraction angiography in one. RESULTS: The main findings of right Iobar agenesis of the liver were nonvisualization of the right portal vein and absence of liver tissue to the right of gallbladder. The findings of left Iobar agenesis were nonvisualization of left portal vein, absence of liver tissue to the left of the gallbladder, and absence of ligamentum teres. The ancillary finding of the Iobar agenesis was visualization of less than three hepatic veins. CONCLUSION: It is important to consider Iobar agenesis of the liver in differential diagnosis when imaging studies reveal abnormal portal vein branches, unusual position of gallblader, absence of ligamentum teres, and visualization of less than three hepatic veins.

PURPOSE: To evaluate the diagnostic value of magnetic resonance(MR) imaging in the differentiation of benign and malignant soft tissue masses. MATERIALS AND METHODS: MR examination of 47 patients with pathologically proven soft tissue masses were reviewed. This series included 19 malignant and 28 benign masses of upper and lower extremities, body, and neck. Lesions were evaluated for their margin, signal intensity and homogeneity, pattern and degree of enhancement, involvement of the adjacent tissue, and degree of surrounding edema. RESULTS: Sixteen of benign lesions(57.1%) had well-defined and smooth margin. The tumor margin was irregular in nine lesions(47.4%), however, smooth margin was noted in five cases(26.3%) of malignant lesions. On T2-weighted images, signal inhomogeneity was noted in 84% of malignant lesions and 32% of benign lesions. On Gd-DTPA enhancement study, all malignant lesions(n=18) showed enhancement and 89% showed heterogeneously enhancing pattern. Neurovascular involvement was observed more often in malignancy(n=7) compared to benign lesion(n=1). Direct invasion of the adjacent bone was noted only in malignant lesions(n=3). Surrounding edema was revealed in two benign and 11 malignant lesions. CONCLUSION: MR imaging appears useful for differentiating malignant and benign lesions by identifying tumor margin, signal homogeneity of tumor, pattern and degree of enhancement, involvement of adjacent tissue, and surrounding edema. The nature of the lesion can be determined in the majority of cases although no unique criterion to differentiate benignancy and malignancy is identified.

OBJECTIVE: To evaluate the efficacy of low dose gonadotropin releasing hormone agonist(GnRH-a) therapy combined with high dose human menopausal gonadotrpin(hMG) following estrogen & progesteron therapy for poor responders. METHODS: From May 1997 to Feb 1999, 36 patients who were defined as poor responders on previous consecutive two and more superovulation cycles were randomly allocated to lowdose GnRH-a short protocol with high dose hMG protocol pretreated with estrogen & progesterone(E/P therapy)(n=16)(study group) and the clomiphene citrate with hMG(n=20)(control group). All patients were planned to undergone in-vitro- fertilization(IVF) and embryo transfer(ET) after controlled ovarian hyperstimulation(COH). RESULTS: Two groups were similar with respect to clinical features and basal FSH and E2 levels. The mean level of E2 on day 5, 304.3+/-148.ng/ml in study group was significantly higher than that in control group, 182+/-34.9ng/ml. The mean levels of E2 on hCG day was also significantly higher in study group than control group(1324+/-320ng/ml, vs 414+/-168ng/ml). The mean day of hCG day in study group, 12.3+/-0.3 was shorter than that in control group, 13.8+/-0.4. The concellation rates of cycles were significantly lower in study group than control group(13.2% vs 84.2%). But clinical pregnancy rates did not showed the significant difference between two groups. CONCLUSION: The study suggested that a lowdose GnRH-a short protocol with high dose hMG pretreated with estrogen & progesterone can improve the ovarian response in poor responder group.

This study was performed to identify the effect of the hydrosalpinx fluid on sperm motility. It has been reported that the patients with hydrosalpinx show the outstandingly lower success rate than other patients having infertility by different factors. It is unclear that the cause of it is influenced by hydrosalpinx fluid directly or by secondary chronic inflammation of endometrium. We wanted to know if the hydrosalpinx fluid influences sperm motility parameters directly such that it is related to the development of infertility. Therefore, using computer assisted semen analyzer (CASA), we observed, from February to July, 1997, how sperm motility, sperm progressive motility, sperm curvilinear velocity, sperm lateral head displacement, sperm straightness and sperm linearity change after treating normal sperm with hydrosalpinx fluid to evaluate sperm function on infertility. The result was that the study group (n=32) has the tendency to differ from the control group (n=32) on sperm motility, progressive motility, curvilinear velocity, lateral head displacement, straightness and linearity. We concluded that the hydrosalpinx fluid, with varying degree, directly has the harmful effects on sperm motility parameters, that is, curvilinear velocity, lateral head displacement and linearity of sperm which are related to the hyperactivation, hence decreased capacitation.
