Coronary arteriovenous fistula is relatively rare disease and originates more commonly in the right than in the left cononary artery. We report one case of cononary arteriovrnous fistula which we have experienced recently in 22 years old female, who has complained of dyspnea on exertion and intermittent anterior chest pain radiating to the left shoulder for several years. It was detected by transthoracic and transesophageal echocardiography and confirmed by cardiac catheterization and coronary angiography. In this case, the fistula was originated from the right coronary artery and drained into the posterior wall of the right ventricle, the coronary artery was dilated(diameter=1.5cm) and tortuous and significant shunt was measured(Qp/Qs=2.31). The opening of the fistula draining into right ventricle was obliterated with sutures.

In so-called primary osteoarthritic knees, there may be secondary osteoarthritis due to the instability from chronic cruciate ligament and/or meniscal tear. The purpose of this study is to compare the findings of bone single-photon emission computed tomography(SPECT) and those of simple radiography in osteoarthritic knees which we consider as primary on the status of anterior cruciate ligament(ACL). We reviewed the preoperative bone SPECT and simple radiography of forty-three osteoarthritic knees in 23 patients who underwent total knee arthroplasty between 1995 and l996. We divided the cases into two groups on the status of ACL: thirty intact ACLs(Group I), thirteen insufficient ACLs(Group II). Meniscal tear and/or ACL insufficiency were found in 38 of 43 knees, As regards with presence of osteophytes and sclerotic changes on simple radiograph, there was no significant differences between group I and II. Joint space narrowing was more prominent and diffuse in group I(medial 29, lateral 24) than group II(medial 7, lateral 6). Bone SPECT showed diffuse uptake in group I(medial 30, lateral 23), but less uptake on the lateral compartment(medial 13, lateral 3) in group II. In ACL-intact osteoarthritic knees, joint space narrowing on simple radiograph and hot uptake on bone SPECT were more prominent and diffuse than in ACL-insufficient knees. Clinical relevance is still uncertain and further investigation is needed.

It has been well documented that dysfunction of the Eustachian tube if the main cause of middle ear disease in most cleft palate patients. The middle ear disease is refractory to medical treatment and has frequent recurrences; the final results may end up with chronic otitis media and/or hearing loss. Currently, myringotomy with placement of ventilation tube in early infant stage have been widely accepted for treatment of otitis media in cleft palate patients. We calculated the frequency of the occurrence of otitis media in cleft palate patients who have received palatoplasty in our clinic. Preoperative otoscopic examination and tympanometric test were taken in all patients. We performed tympanostomy and ventilation tube insertion at the time of palatal repair on every patients who had evidence of otitis media in the preoperative otologic examinations. Since November 1996, 79 patients received palatoplasty and among these 63 patients(79.7%) received bilateral ventilation tube insertion simultaneously. We confirmed the previously documented high prevalence of otitis media in cleft palate patients and understood the importance of preoperative otologic examinations in the managements of cleft palate.

To increase the survival area of the venous flap, we studied the arterialized venous flap in a rabbit ear model. The ears of 12 New Zealand white rabbits(n=24) were randomized into three groups, group A receiving arterio-venous anastomosis 14 days before the arterialized venous flap elevation; group B receiving bipedicled flap elevation 14 days before arterialized venous flap elevation; group C receiving no pretreatment before the arterialized venous flap elevation. Tc -pertechnetate scan was performed on all groups immediately after the arterialized venous flap elevation to evaluate the blood flow of the flap. The survival area of the flap was measured 14 days after the arterialized venous flap elevation. Average ratio of survival area was 92% in Group A, 88% in group B, which were comparatively higher than the 12% in group C. The entire flap was visualized in groups A and B on scan images, however, only the proximal area of the anterior and posterior marginal vein was visualized in group C. Flap survival pattern was similar to that of the scan image and the slope of time-activity curve of groups A and B was much steeper than that of group C. High survival rate of group A, which received the arterio-venous anastomosis as a pretreatment, may be due to the decrease of resistance of outflow during the 14 days. Anticipated mechanisms involved are, valve insufficiency due to high pressure arterial inflow, development of vascular collaterals in the flap, and opening of arteriovenous(A-V) shunt. Bipedicled flap elevation as a pretreatment may not effect on valves, however, may impair the sympathetic nerve and cause ischmic stimuli which in turn may develop vascular collaterals and make an opening of the A-V shunt.

Treatment of Leptomeningeal carcinomatosis (LMC) from solid cancers has not advanced noticeably since the introduction of intra-cerebrospinal fluid (CSF) chemotherapy in the 1970's. The marginal survival benefit and difficulty of intrathecal chemotherapy injection has hindered its wide spread use. Even after the introduction of intraventricular chemotherapy with Ommaya reservoir, frequent development of CSF flow disturbance, manifested as increased intracranial pressure (ICP), made injected drug to be distributed unevenly and thus, the therapy became ineffective. Systemic chemotherapy for LMC has been limited as effective CSF concentration can hardly be achieved except high dose methotrexate (MTX) intravenous administration. However, the introduction of small molecular weight target inhibitors for primary cancer treatment has changed the old concept of 'blood-brain barrier' as the ultimate barrier to systemically administered drugs. Conventional oral administration achieves an effective concentration at the nanomolar level. Furthermore, many studies report that a combined treatment of target inhibitor and intra-CSF chemotherapy significantly prolongs patient survival. Ventriculolumbar perfusion (VLP) chemotherapy has sought to increase drug delivery to the subarachnoid CSF space even in patients with disturbed CSF flow. Recently authors performed phase 1 and 2 clinical trial of VLP chemotherapy with MTX, and 3/4th of patients with increased ICP got controlled ICP and the survival was prolonged. Further trials are required with newly available drugs for CSF chemotherapy. Additionally, new LMC biologic/pharmacodynamic markers for early diagnosis and monitoring of the treatment response are to be identified with the help of advanced molecular biology techniques.

BACKGROUND: Descending necrotizing mediastinitis(DNM) is a serious complication originating in odontogenic or oropharyngeal infection with previously reported mortality rates of 25% to 40%. We retrospectively reviewed the 4 years of our surgical drainage and debridement in DNM. MATERIAL AND METHOD: We studied 7 cases diagnosed as DNM from 1997 through 2000. Primary oropharyngeal infection lead to DNM in four cases(57%) and odontogenic abscess in three cases(43%). All patients were received emergent cervicotomy and thoracotomy or sternotomy for debridement of necrotic tissue and mediastinal or pleural drainage. RESULT: Five cases were evolved well and were discharged after a mean of 42 days. Two patients(28.6%) died. Three patients required reoperation due to local surgical complication; empyema(two) and impending cardiac tamponade. One of these patients died on 12 post-reoperative day due to great vessel erosion, renal and respiratory insufficiency. The other patient died of broncho- esophageal fistula and asphyxia on 10 postoperative day without reoperation. CONCLUSION: On the basis of experience accrued in treating these patients, early diagnosis by cervicothoracic computed tomographic scan of neck and thorax aids in rapid indication of a surgical approach of DNM. We emphasize that performing early surgical drainage and debridement of necrotic tissues with intensive postoperative care can significantly reduce the mortality rate.

BACKGROUND AND OBJECTIVES: It has been recently reported that coronary artery disease (CAD) is more correlated with postprandial triglyceride (TG) levels than fasting TG levels. We performed this study to compare the patients with CAD to age- and sex-matched controls in regard to postprandial TG levels and to know the effects of fenofibrate on postprandial TG levels. MATERIALS AND METHOD: Serum TG, total cholesterol (C), HDL-C and LDL-C were measured before, and 2, 4, 6, 8, and 24 hours after a high-fat meal in 22 patients (mean: 60 yr) with CAD and 12 normal subjects (mean: 54 yr). The same parameters were also serially measured after the high-fat meal plus fibrate in 10 patients with CAD (mean: 59 yr). RESULTS: he patients group without fibrate showed that more prolonged and exaggerated hypertriglyceridemia following the meal than normal subjects, especially 4 to 8 hours after the meal and that lower HDL-C throughout the test duration. These changes were also persisted when hyperlipidemic patients were excluded out of the patients group. The patients with fibrate did not show such a significant elevation of TG levels 4 to 8hours after the meal compared when normal subjects. The time to reach the peak TG levels after the meal was 4, 6, and 4 hours after the meal in normal subjects, patients with CAD, and fibrate group, respectively. CONCLUSION: Coronary artery disease is clearly related with postprandial hypertriglyceridemia than fasting TG levels and postprandial hypertriglyceridemia can be somewhat prevented by fibrate.

Angiodysplasia as a cause of gastrointestinal bleeding is increasingly recognized with the advancement of diagnostic technique. Most of angiodysplasia occur in old age and their sizes rarely exceed a few millimiters in diameters. Angiodysplasia of the gastrointestinal tract in young adult and adolescent is a very rare cause of gastrointestinal bleeding and thought to be a distinct clinicopathologic entity. We experienced a case of angiodysplasia in young man with chronic upper gastrointestinal bleeding and iron deficiency anemia required periodic red blood cell transfusion. It is a very rare case that angiodysplasia involved entire stomach and total gastrectomy was necessary to manage chronic bleeding.

Tie-over dressing is commonly used in order to immobilize the skin graft. The classic method takes too much time and effort, and various apparatuses of the other modifications are somewhat large and bulky, especially in the surgery for hands, therefore, we have developed a simplified method for tie-over dressing. We placed several key stitches with absorbable suture material, and passed silk sutures from one margin of the graft to the opposite without tying. Then after putting saline-soaked cotton balls below and above the silk sutures, we tied the silk suture together applying appropriate pressure. This method has the following advantages: 1. speed of application 2. double compression 3. easy to remove

Tanzer introduced the auricular reconstruction using autologous rib cartilage & full thickness skin graft for congential microtia correction in 1959. After then, many surgeons adapted various modified methods for total ear reconstruction. However, there are some problems in the stage of ear elevation with the conservative technique. Due to scar contracture, the auriculocephalic angle cannot be maintained with the skin graft alone. Nagata tried to overcome this problem by inserting rib cartilage covered by temporoparietal fascia to the elevated cartilage frame. However, this technique also induced several problems. 1st, it leaves a long scar and alopecia on the temporal scalp. 2nd, Nagata method requires a lot of cartilage in order to fabricate the 3-dimensional framework, sometimes leaving no cartilages to be used for the semilunar pillow in the ear elevation procedure. 3rd, this method cannot be used if the temporoparietal fascia was already used for another reason such as cartilage framework exposure. To overcome these problems, we used the silicone block and mastoid fascia flap instead of semilunar cartilage pillow and temporoparietal fascia flap. Since silicone is not an absorbable material, it can maintain good auriculocephalic angle. Furthemore, due to the excellent blood circulation of the mastoid fascia flap, there is a strong resistance to postoperative complications such as infection and extrusion. Other advantages are that it leaves short scars and is esthetically tolerable. This method may preserve the temporoparietal fascia and therefore, may be prepared for the 2ndary operation in case of the exposure of framework. From March 1995 to July 1997, 18 patients (14 males and 4 females) who ranged in age from 9 to 23 years underwent ear elevation using the silicone block and mastoid fascia flap. These patients had previous rib cartilage graft operations at 6 months before these operations. We did not find any complications such as infection, silicone implant extrusion and decreased auriculocephalic angle. During 6 to 26 months follow-up period (average follow-up period; 12 months), there was no case of decreased auriculocephalic angle. The clinical result of this technique was excellent at the stage of ear elevation.
