  • Superior Vena Cava Syndrome: Dacron and Nylon graft between the left innominate vein and the right atrial appendage. Two cases with typical superior vena cave syndrome treated by by-pass graft between the left innominate vein and the right atrial apepndage were presented. One of them was a 58 year old farmer who suffered from marked swelling of the neck and upper half of body, the other was a 50 years old government employee who had acutely progressive symptoms of superior vena cave obstruction. Both of cases revealed that [1] cubitel venous pressure was markedly increased. [2] tumors were noted in the posterior mediastinum by laminography. [3] preoperative cavogram showed the occlusion of superior vena cava and marked collaterals. Dacron and Nylon graft were inserted between the left innominate vein and the right atrial appendage. Postoperatively, the symptoms were relieved markedly, showing edema free face and decreased cubital venous pressure. Postoperative cavogram showed patent graft. Histologically the first case was diagnosed as squamous cell carcinoma and the second as undifferentiated carcinoma, originated probably from bronchus. Total doses of 3150 r X-ray irradiation and 5000 mg of 5-FU were administered in each cases. The first case expired 11 months postoperatively without recurrence of superior vena cave obstruction symptom and the second case is living now without obstruction signs, 4 months after by-pass operation.

  • In the oral and maxillofacial area, bone defects are created by various reasons and demand for bone grafts, while dental implant implantation has been increased consistently. To solve these problems, there has been development of autogenous tooth-bone graft material (AutoBT$^{(R)}$, Korea Tooth Bank Co., Korea), and we have collected ground reasons to substitute free autobone graft with this material in clinical use. This autogenous tooth-bone graft material is produced in powder type and block type. Block type is useful in esthetic reconstruction of the defect site and vertical and horizontal augmentation of alveolar bone because this type has high strength value, well maintained shape and is less absorbed. Therefore, the author of this study gained favorable result by grafting the block type autogenous tooth-bone graft material after dental implant implantation on the bone defects of the mandibular molar extraction site. Moreover, the author represents this case with literature review after confirming bone remodeling on the computed tomography image and by histological analysis.

  • Purpose: Previous transtibial double bundle posterior cruciate ligament (PCL) reconstruction methods have several problems in graft length and tibial fixation. We introduce new surgical method that is less restrictive by graft length and is more stable with single tibial fixation. Operative technique: After diagnostic arthroscopy, we prepare the graft, ream the tibial tunnel and perform the procedure for TransFix tibial fixation. Femoral 2 tunnel is made and graft is passed via anteromedial (AM) portal. Tibial fixation is done and femoral 2 graft is fixed sequentially at each knee position. Conclusion: TtransFix tibial single fixation method in double bundle PCL reconstruction provides more stable fixation, more free graft selection and prevents graft damage by passing the graft via AM portal.

  • The usual methods for the re-attachment of coronary ostia to the ascending aortic conduit have several disadvantages and potential complications. A novel, straight forward technique is described that allows for tension free anastomoses to be co structed with minimal risk of blood loss and a reduced risk of reoperation for false aneurysms at the anastomoses. We performed this technique for the treatment of a 40-yrs-old male patient of acute aortic dissection (Stanford Type A, DeBakey Type I) with severe aortic re- gurgitation. The techinque comprised anastomosis of a beveled interposition tube graft to the left main coronary artery ostium, and its proximal anastomosis to the ascending aortic graft after seating the com- posite valve graft in the prepared aortic annulus. With this technique, the low-Iying or distant left main coronary ostium can be easily reattached to the ascending conduit without undue tension.

  • Acrylic acid has been grafted onto nylon fabric with ceric salts and ${\gamma}$-rays from Co-60 as initiators. The distribution of molecular weight of the grafted polyacrylic acid has been determined and it was found that the ratio of weight-average and number-average molecular weight was higher in room temp. than in low temp. (-184$^{\circ}C$). The weight-average molecular weight of the polyacrylic acid was calculated from viscosity measurements in sodium hydroxide solution. The factors affecting graft polymerization of acrylic acid onto nylon were examined. A possible mechanism that the oxidation of nylon probably takes place at the methylene group attached to nitrogen to give a free-radical was discussed.

  • Cerebrospinal fluid (CSF) rhinorrhea usually occurs as a result of trauma including operation. Unheated CSF rhinorrhea may induce major morbidity such as meningitis and brain abscess, etc. This paper presents a review of four cases of traumatic CSF rhinorrhea Sites of CSF leakage were easily found out by intrathecal fluorescent dye injection. Surgery was performed by external ethmoidectomy approach and dural tear and bone defect was repaired with abdominal fat and free mucosal graft taken from amputated middle turbinates. We conclude that repair using free fat and mucosal graft via external ethmoidectomy approach could be accepted as the intial method of CSF rhinorrhea management.

  • Oral lichen planus (OLP) is a chronic oral mucosal disease affecting the buccal cheek, tongue, palate, lip, and gingival mucosa. Lesions in the gingiva make it difficult to control dental plaque due to pain. As a result, the disease is often accompanied by gingivitis or periodontitis. If OLP and dental plaque are not properly managed, the patient's periodontal condition will worsen. Thus, clinicians treating OLP should emphasize periodic visits and dental plaque control. Here, we report the management of a patient who struggled with OLP for 20 years and discuss the importance of periodic regular observations and active periodontal management.

  • Reconstructive surgical procedures for hypopharyngeal and cervical esophageal defects have still a lot of technical defficulties and varieties to be performed as a optimal treatment according to the clinical situation patient faced. We have experienced a case of successful reconstruction of cervical esophageal defect, which was resulted from graft failure of free jejunal transfer in 43 year old male with eso-phagocutaneous fistula, using free fasciocutaneous dorsalis pedis flap. This article describes the review of our case and literature relevant the reconstructive maneuvers of cervical esophageal defects.
