The purpose of the present study was to evaluate the easiness of suture and fixation of modified total ring prostheses (m-TRP). Twelve healthy dogs (B.W.2-10 kg) were randomly assigned to three groups. In group A (3 dogs), total ring prostheses was fixed by penetrating a suture material through tracheal mucosa. In group B (3 dogs), TRP was fixed by suturing on tracheal cartilage and muscular layer not penetrating through tracheal mucosa. m-TRP was applied to the cervical portions (group M-C,3 dogs), and thoracic portions (group M-T,3 dogs). Operating time of group M-C (37.33$\pm$6.80 min.) was shorter than those of groups B (83.33$\pm$8.50 min.) and A (63.33$\pm$11.06 min.) (p＜0.01). Clinical complications were minimal and limited to mild, short-term hematoma, vomiting, edema, and inflammation. Coughing remarkably decreased in group B rather than group A. Dyspnea was not showed in group A, B, and M-C, but group M-T had a mild dyspnea. Gross postmortem findings were similar in all groups. Mild adhesions were present between prostheses and adjacent structures, but tracheal lumen was clean. Severe adhesions were present where m-TRP had been applied in the thoracic portions. Histopathologic abnormalities included mild to moderate adventitial and periprosthetic fibrosis and mild adventitial inflammation. The present study indicated that m-TRP were easier in suture and fixation than TRP and had no differences in support for trachea and side effects.

Traumatic brainstem hemorrhage after blunt head injury is an uncommon event. The most frequent site of hemorrhage is the midline rostral brainstem. The prognosis of these patients is poor because of its critical location. We experienced a case of traumatic brainstem hemorrhage. A 41-year-old male was presented with drowsy mentality and right hemiparesis after blunt head injury. Plain skull radiographs and brain computerized tomography scans revealed a depressed skull fracture, epidural hematoma, and hemorrhagic contusion in the right parieto-occipital region. But, these findings did not explain the right hemiparesis. T2-weighted magnetic resonance (MR) image of the cervical spine demonstrated a focal hyperintense lesion in the left pontomedullary junction. Brain diffusion-weighted and FLAIR MR images showed a focal hyperintensity in the ventral pontomedullary lesion and it was more prominent in the left side. His mentality and weakness were progressively improved with conservative treatment. We should keep in mind the possibility of brainstem hemorrhage if supratentorial lesions or spinal cord lesions that caused neurological deficits in the head injured patients are unexplainable.

Thyroid cancer, the most common cancer of endocrine neoplasms, has tremendous variation in tumor biologic behavior. There is no consensus about treatment mode to prevent recurrences despite of recent advance in understanding characteristics of thyroid cancer. So, we have made a clinical analysis and follow-up study of recurred 27 cases among 189 cases treated under the diagnosis of thyroid carcinoma in the department of surgery, Chonnam University Hospital from February, 1982 to February, 1992 to clarify our experience about the characteristics of recurred thyroid cancer. The results were as follow: According to the pathological classification of recurred thyroid cancer, recurrence rate was 11.6% in papillary carcinoma, 15.6% in follicular carcinoma, 37.5% in medullary carcinoma, 66.7% in undifferentiated carcinoma, respectively, and the mean recurrence rate of thyroid cancer was 14.3%. The recurrence rate according to age was 28.6% in 8th decade and 17.9% in 4th decade. The recurrence rate according to sex was not singificant(15.6% in male: 14% in female). The mean period to relapse was 4 years 6 months in papillary carcinoma, 2 years 5 months in follicular carcinoma, 2 years 1 months in medullary carcinoma, 2 years 6 months in undifferentiated carcinoma. The recurrence rate according to previous operating methods, such as performing lymph node dissection or not, mode of thyridectomy, type of lymph node dissection was statisfically non-specific. Common recurrent sites of papillary and follicular carcinoma was cervical lymph node and remained thyroid tissue. Medullary and undifferentiated carcinoma was noted in multiregional or systemic involvement Reoperation was performed with complete resection of recurred or metastatic mass, such as radical neck dissection or mass extirpation from involved organs as possible. The postoperative complications were 2 cases of horseness, and 1 case with hematoma, transient hypocalcemia, wound infection, and pulmonary insufficency, respectively. 5-year survival rate was 85.5% in papillary carcinoma, 66.7% in follicular carcinoma. 50% in medullary carcinoma, and 50% in undifferentiated carcinoma. We concluded that recurrence in thyroid cancer give a reconsideration to previous conservative therapy and more extensive surgical procedures for thyroid cancer including lymphatic dissection are recommanded to prevent recurrences in selected cases if possible.

배경: 흉곽출구증후군은 상지에 분포하는 신경, 혈관 다발의 눌림에 의해 통증, 감각이상 및 부종 등이 발생하는 질환으로 국내에는 그 보고된 예가 적고 특히 수술까지 이른 경우는 드물다. 상기 질환으로 수술적 치료를 시행 받은 환자의 임상양상 및 그 결과를 분석하고자 한다. 대상 및 방법: 2002년 5월부터 2004년 10월까지 상기 질환으로 진단되어 수술까지 시행한 16명을 대상으로 하였다. 수술의 적응증은 1)일상생활을 수행하는데 지장을 줄 정도의 통증 및 감각마비, 부종 등의 증상이 있으며 2) 적절한 물리치료 후에도 증상의 호전이 없고 3) MRI및 혈관촬영에서 늑골 및 쇄골에 의하여 흉곽 출구의 구조물이 확실하게 눌린 소견이 있으며 4)경추부 추간판 탈출증, 근염, 상완신경총 이하의 신경병변 등을 배제하기 위한 검사를 하여 해당사항이 없는 환자에 한정하였다. 수술 방법은 12예는 액와부접근법을, 2예는 쇄골상부 접근법을, 나머지 2예는 쇄골하부접근법을 사용하였다. 걸과: 환자의 연령은 평균 23.9세($\pm$6.3)였으며 남자가 15명으로 대다수를 차지하였다. 늑골 기형이 있는 환자가 4예(25.0$\%$)였고 나머지는 늑골의 이상은 없었다. 우측병변이 8예(50.0$\%$), 좌측병변이 5예(31.3$\%$), 양측병변이 3예(18.7$\%$)였다. 수술 후 9$\∼$26개월의 추적관찰에서 재발률은 12.5$\%$ (2/16)였다. 합병증으로는 1예에서 수술 중 팔신경얼기의 견인에 의한 손상으로 발생한 척골 신경 마비와 술 후 사진에서 호전되었음에도 지속적인 통증이 1예 있었고, 지방괴사와 혈종에 의한 상처의 파열 및 재수술이 3예였다. 결론: 흉곽유출증후군 환자에서 수술이 효과가 있는가에 대하여는 논란이 되고 있으나, 물리 치료에 반응이 없는 환자에게는 적극적인 수술이 좋은 치료 방법이며 빠른 사회 생활의 복귀에 도움이 될 것으로 생각된다.
