Acute mobile thrombus of the abdominal aorta after chemotherapy is a very unusual finding, which can be a potential source of arterial embolism. We report here on a case of an acute mobile aortic thrombus with renal infarction. We successfully treated the patient with hybrid operation-open surgical and endovascular approach. Our case shows that hybrid treatment using wire-directed balloon catheter thrombectomy is a feasible, minimally-invasive treatment for a mobile aortic thrombus.

Fetal echocardiography is used by means of decleration of fetal cardiac anaztomy, to estabilish the diagnosis of congenital heart disease in utero. We attemped fetal echocardiography to ninty three pregnant women after intra uterine period 24 weeks, and estimated cardiac circumference, cardiac axis, pulmonary atery root diameter, arortic root diameter, diameter of inferior vena cava, diameter of superior ve studied how these estimates associate with following gestational na cava, and fractional shortening of ventricles. We ages. Cardiac axis was on the average 37.28 degree and cardiac apex was located in anterior left side of chest area. Aortic root diameter was 0.227 GA-0.043mm (GA=gestational age) at systolic phase, 0.203 GA+0.421mm at diastolic phase. Pulmonaly root diameter was 0.271 GA-0.029mm at systolic phase, 0.251 GA-0.067mm at diastolic phase. Thoracic aorta diameter was 0.195 GA+0.109mm at systolic phase, 0.198 GA+0.794mm at diastolic phase. Fractional shortening was 0.24 (1 Standard Deviation=0.11) in right ventricle, 0.23(1 SD=0.154) at left ventricle, and so ratio of right and left ventricle was 1.04(1 SD=0.51). Once normal fetal cardiac anatomy is understood, structural defects and/or alternation of function can be evaluated antenatally.

Epiblepharon is frequently encountered n oriental eyelid, especially in children. It is characterized by a horizontal fold of redundant skin and abundant orbicularis muscle near lid margin, which the lashes vertically, or posteriorly towards the eye. Surgical therapy of epiblepharon in correcting the trichiasis includes lid bracing sutures, burried sutures, skin resection, a Hotz procedure or its modification, and a Jones procedure. In our opinion, these procedures are not sufficient, because these procedures will not correct the epicanthal folds. Epicanthal folds have been a one of the characteristics of Asian over 50 percents of population in Japan and South Korea, and it either reduce the aesthetic result of the double-eyelid procedure or make the correction of the entropion and epiblepharon difficult. Although many surgical procedures are available to eliminate epicanthal folds, scarring on the medial canthus is in still and obstacle for surgeons to overcome. From January of 1998 to October of 1998, we used half z-plasty procedures in 5 cases to correct epicanthal folds in epiblepharon. There were few complications in our series. We believe that half z-plasty can get a good result in the correction of epibolepharon and oriental epicanthal folds.

PURPOSE: To evaluate the results of antegrade interlocking intramedullary nailing for complex fractures of the proximal and midshaft of the humerus. MATERIALS AND METHODS: We retrospectively analyzed the clinical and radiologic results in 11 cases, which were treated by antegrade interlocking intramedullary nail. We assessed clinical outcomes according to ASES scoring system and radiological result. RESULTS: All cases had bony union and the mean union period was 14.7 weeks. Postoperative complications were 1 loss of fixation, 2 proximal protrusion of nail and 2 temporary shoulder pain. A case with loss of fixation was treated open reduction and refixation and had union at 14 weeks postoperatively. The mean ASES score was 85.9 and the clinical outcomes were 4 excellent, 5 good, 1 fair and 1 poor. CONCLUSION: Intramedullary nailing for complex fractures of the proximal and midshaft of the humerus can offer a reliable treatment option.

The purpose of this article is to report on the first known Korean case of Susac syndrome. An 18-year-old female came to our clinic reporting blurred vision of the left eye for 2 days. She also complained of decreased hearing with tinnitus of the right ear and mild headache. She was previously healthy and had no remarkable medical history. Best-corrected visual acuity was 20 / 50 in the left eye and 20 / 20 in the right eye. An axiomatic triad of ocular, cochlear, and neurologic involvement was observed in the patient. Fluorescein angiography showed branched retinal arterial occlusions in the left eye. A sudden right sensorineural hearing loss was observed on audimetry. Magnetic resonance images showed a hyperintense lesion in the white matter around the corpus callosum. The patient was treated with high doses of systemic corticosteroids, and no neuropsychological sequelae were observed. This is the first case report of Susac syndrome in Korea. In cases of retinal arterial occlusion with hearing loss or neuropsychological symptoms, Susac syndrome should be suspected.

Total hip arthroplasty in patients with chronically dislocated hips poses many challenging technical problems. Abnormal relationship of bones and soft tissues occurs in chronic complete dislocation of the hip (grade IV, Crowe's classification). Problems in placing the acetabular component in the true acetabulum include, first how to cover the acetabular component sufficiently, second how to fix it securely and last how to avoid excessive stretching of the neurovascular structures such as the sciatic nerve. The authors have introduced a technique of one stage distal femoral shortening in order to avoid excessive stretching of the neurovascular structures. From December 1988 to May 1996, the total hip arthroplasties combined with one stage distal femoral shortening were carried out in chronic complete dislocation of 44 hips (grade IV, Crowe's classification) and followed-up more than two years. This method has several advantages: It preserves wide and healthy proximal metaphysis of the femur, does not need greater trochanteric osteotomy, and provides many chances to choose the appropriate stem size and shape, especially in cementless total hip arthroplasty.

The treatment of choice for post-intubation tracheal stenosis is partial tracheal resection and end-to-end anastomosis. The surgical treatment of tracheal restenosis that results from unsuccessful repair of post-intubation tracheal stenosis is not easy. Failed reoperation results in permanent tracheostomy and loss of voice. If the first operation fails, about 4~6 months of period for resolution of inflammatory reaction, edema, and fibrosis is needed. The exact evaluation of the patient's status is necessary and success rate of reoperation for the appropriate candidates is over 90%. We report the results of treatment in two cases of tracheal restenosis that resulted from unsuccessful repair of post-intubation tracheal stenosis with review of literatures.

BACKGROUND: Myasthenia gravis is a rare autoimmune disease involving acetylcholine receptor and its autoantibody on neuromuscular junction. The methods of treatment are medical treatment and surgical thymectomy. In this paper we analyzed the result of thymectomy and the factors affecting the postoperative symptom improvement. MATERIAL AND METHOD: This study obtained medical records of 37 patients who received the thymectomy for myasthenia gravis from March 1986 to December 1998. RESULT: Out of 37 cases, 21 cases(57%) showed improvement, of which 8 cases (50%) in the group of thymoma(n=16), and 13 cases (62%) in the group of thymic hyperplasia(n=21) showed the improvement of symptoms. Postoperative complications were respiratory insufficiency due to aggravation of symptoms after operation, including tracheal intubation for ventilator support in 9 cases, pneumonia in 3 cases, pneumothorax in 2 cases and left vocal cord palsy in 1 case. There was one postoperative mortality. The relation between postoperative improvement and sex(P=0.3222), age(P=0.7642), thymic pathologic variants,(P=0.4335) and classification of thymoma(P=0.20) showed no statistically significant correlation. However, the lower grade of preoperative symptoms can predict the lower grade of postoperative symptoms significantly(P=0.0032). Follow up study to 36 postoperative survivors was performed in October 2002 based on the out-patient records and call with patients. Out of 36 cases, 33 cases(91.7%) could be investigated and 3 cases could not. Mean follow up period was 83.2 months. Out of 33 cases, 25 cases(75.8%) showed symptomatic improvement, of which 8 cases(53.3%) in the group of thymoma(n=15) and 17 cases(94.4%) in the group of thymic hyperplasia(n=18) showed the improvement of symptoms. CONCLUSION: In myasthenia gravis, thymectomy showed the good improvement, and more important factor affecting the improvement of symptoms was the grdae of preoperative symptoms. Also midterm and long term follow up results showed good symptomatic improvement.

PURPOSE: To compare the effectiveness of intravitreal injections of bevacizumab and ranibizumab in patients with treatment-naive polypoidal choroidal vasculopathy (PCV). METHODS: Records from 106 consecutive patients who received intraviteral bevacizumab (n = 58, 1.25 mg) or ranibizumab (n = 52, 0.5 mg) for treatment of PCV were retrospectively reviewed. After three initial monthly loading injections, injection was performed as needed. The main outcome measures included best-corrected visual acuity (BCVA), foveal central thickness (FCT) as assessed by spectral domain optical coherence tomography, and the changes in polypoidal lesions based on an indocyanine green angiography. RESULTS: The average number of injections was 3.31 +/- 1.25 in the bevacizumab group and 3.44 +/- 0.92 in the ranibizumab group. Mean logarithm of the minimum angle of resolution of BCVA from baseline to 6 months after injection improved by 0.17 in the bevacizumab group (p = 0.03) and by 0.19 in the ranibizumab group (p = 0.01). Average FCT decreased from 322 +/- 62.48 microm to 274 +/- 40.77 microm in the bevacizumab group (p = 0.02) and from 338 +/- 50.79 microm to 286 +/- 36.93 microm in the ranibizumab group (p = 0.02). Polyp regression rate was 20.7% (12 of 58 eyes) in the bevacizumab group and 21.2% (11 of 52 eyes) in the ranibizumab group. There was no statistically significant difference between groups in BCVA improvement achieved, FCT improvement achieved, and polyp regression rate between groups. CONCLUSIONS: Intravitreal injections of bevacizumab and ranibizumab have similar effects in stabilizing of visual acuity, macular edema, and regression of polypoidal complex in PCV eyes over the short term.
