뇌척수액 비루는 그 원인에 따라 외상성 뇌척수액 비루와 비외상성 뇌척수액 비루로 나뉘어지며 이 중 외상성 뇌척수액 비루가 대부분을 차지한다. 또한 외상성 뇌척수액 비루는 사고에 의한 것과 수술의 합병증으로 인한 의인성 뇌척수액 비루로 분류되어질 수 있다. 이비인후과 영역에서의 의인성 뇌척수액 비루로는 두개저 수술, 사골동 수술 등에서 발생될 수 있으며 이러한 수술의 증가에 따라 그 빈도가 점차 증가 추세에 있다. 최근 저자들은 의인성 뇌척수액 비루 2례를 경험한 바 각각 전사골동 상벽 및 사상판의 결손부위를 통한 뇌척수액 비루를 비내시경을 이용하여 정확히 발생부위를 확인할 수 있었으며 측두근 근막, tissue glue, Gel-foam을 사용하여 2례 모두에서 만족할만한 성과를 얻은 바 문헌 고찰과 함께 보고하는 바이다.

Schwannomas are benign neurogenic tumors arising from the peripheral nerve sheath and rare in the nasal cavity and paranasal sinus. About 4% of schwannomas in the head and neck area arise in the sinonasal cavity. As unilateral nasal masses in the nasal cavity and paranasal sinus, schwannomas are likely to be mistaken for more common lesions such as nasal polyps or mucoceles. We recently experienced a case of schwannoma on the ethmoid sinus in a 33-year-old male which was surgically removed. Herein, we report this unusual case of schwannoma on the ethmoid sinus with a brief review of literature.

Background: Although great concerns have been raised regarding the suitability of the use of the radial artery as a bypass conduit after transradial catheterization, there has been no studies that examined this issue in Korea. The purpose of this study was to compare clinical and angiographic results of radial artery grafting between patients with and without previous transradial catheterization. Material and Method: From January 2000 to February 2004, a total of 93 patients underwent coronary artery bypass grafting using the radial artery: 49 patients received preoperative transradial catheterization for coronary angiography (group I) and 44 patients did not (group II). These patients were retrospectively reviewed. Result: There was no significant difference in sex ratio, age, clinical diagnosis, risk factors, ejection fraction and early clinical outcomes between two groups. The graft patency rates in groups I and II were both 100% in the internal thoracic artery and in the radial artery, and 85% and 86% in the saphenous vein. respectively. The stenosis-free graft patency in groups I and II were 93% and 81% in the radial artery respectively but no statistical significance was shown. Conclusion: There was no significant difference in graft patency at postoperative coronary angiography between two groups. Radial artery graft after transradial catherization seems to be suitable for bypass conduit in short-term analysis.

In off-pump coronary artery bypass grafting (CABG), multiple proximal anastomosis may increase the risk of cerebral embolism (air, debris) and aortic injury (dissection, pseudoaneurysm). Radial artery (RA) has no intraluminal valve such as saphenous vein. We applied Cabrol technique using aortic root replacement for proximal anastomosis in off-pump CABG. Cabrol technique using RA graft can reduce numbers of proximal anastomosis and reduce number of aortic manipulation in off-pump CABG. We report a Cabrol technique for proximal anastomosis in off-pump CABG with RA graft.

Objective : The purpose of this study is to suggest medical approach to musculoskeletal system disorders using the decoction of Sanghan-Geumgwe. We studied cases of Ling-Gui-Gan-Zao-Tang prescribed patients to evaluate the clinical efficacy in musculoskeletal system disorders Method : We devised medical approach of Sanghan-Geumgwe in musculoskeletal disorders as follows. First, we chose ryeon-je(攣劑) and soo-je(水劑) herb medicine, commonly used in musculoskeletal disorders. In the selected herb group, we designated ryeon-je(攣劑) to be first key herbs, Soo-Je(水劑) as the second key herb, and other herb groups as third key herb. In this sequential selection and exclusion process, herbs were chosen based upon yak-neung-hyo-seon (藥能效選). Combination of those selected herbs drew pre-prescription group, finally prescription were made by the prescription criteria. Results : Based on the medical approach of decoctions of Sanghan-Geumgwe, we chose Ling-Gui-Gan-Zao-Tang to treat many kinds of musculoskeletal system disorders. And we achieved higher results on treatment for musculoskeletal system disorders. Conclusions : The medical approch using the decoctions of Sanghan-Geumgwe is very useful in choosing accurate prescriptions for patients with musculoskeletal system disorders in clinic.

한의학 관점의 진맥위치는 요골동맥상의 촌/관/척 세부위로 나누어진다. 거의 말초에 해당하는 근접한 부위를 세 부분으로 나누어 진맥하여 병을 진단하는데 촌/관/척 위치에 대한 해부학적 혈류역학적 근거는 부족한 상황이다. 본 논문에서는 초음파(VOLUSION730 PRO, GE Medical 미국)를 이용하여 맥진 위치의 혈관굵기, 혈관깊이 그리고 혈류 속도를 측정하고 분석해 봄으로써 맥진 위치의 구조석 차이를 이해해 보고자 한다. 또한 Body Mass Index(BMI)에 따라 혈관의 특성이 달라지는지 파악하고 한의맥진과의 상관관계를 분석해 보았다. 심혈관 질환이 없는 남자 피험자를 각각 BMI 정상인 그룹, 저체중 그룹, 과체중 그룹으로 나누어 5명씩 측정하였다. 좌, 우 손목의 맥진위치(촌, 곽, 척)에서 혈관깊이, 혈관굵기, 혈류속도를 측정하였으며 맥진기(3-D Mac, 대요메디, 한국)를 이용하여 맥파를 측정하였다. 그 결과, 비만도에 따라 혈관의 특징이 다르게 나타남을 알 수 있었으며 한의 맥의 종류 중 부맥과 치맥에 특징이 비만도와 관련 있음을 알 수 있었나 이는 피험자의 혈관 특성과 BMI 정보가 진단에 중요한 지표이며 자동 맥진 알고리즘 개발 시 반드시 고려해야 하는 사항임을 알 수 있다.

In the this research, two simultaneous peaks of radial artery pulse wave and ECG pulse wave measured by using clip-type pulsimeter and ECG were investigated in order to analyze pulse wave velocity. The measured value of a pulse wave velocity is about 5~7 m/s, it is proved one new method to measure an exact value of pulse wave velocity more than the typical biomedical signal monitoring system. This result implies that data measured by the oriental medical diagnosis apparatus as pulsimeter is clinically used in future.

Purpose: Many studies reported anatomy of posterior tibial artery perforator. But, it is not easy to use this flap in clinical case. Methods: Authors performed cadaver dissection on 26 legs from 13 cadavers and identified the number, location, type, length and diameter of perforator. Based on anatomic study, posterior tibial artery perforator flap was performed on 3 clinical cases. Results: The perforator was found on a line drawn from the medial boarder of central patella to posterior boarder of medial malleolus. The main perforator which was longer and greater caliber than others was found was found 13 to 17cm distant from medial boarder of central patella in 23 of 26 leg(88.5%). Average length was 6.2cm and average diameter was 1.4mm. The main perforator was musculocutaneous perforator at 20 of 26 leg(77%). The posterior tibial artery perforator flap was clinically use in 3 cases. All flap were survived without any complication. Conclusion: The author found the main perforator of posterior tibial artery perforator flap was located 15cm distant from medial boarder of central patella within the circle drawn with a radius of 4cm. The posterior tibial artery perforator flap is expected to be used as one of the option for the reconstruction of hand and foot.

Objective : Transsphenoidal approach(TSA) has been used as useful operative method for pituitary tumor but is still controversal in case of cavernous sinus invasion or severe suprasellar extension. This study was performed to evaluate the surgical result, recurrence, effect of adjuvant treatment, especially in cases of suprasellar extension or cavernous sinus invasion. Material and Methods : We studied 56 cases of surgically treated pituitary adenoma that we were able to follow up, treated by TSA from 1993 to 1998. There were 24 cases of suprasellar extension and 11 cases of cavernous sinus invasion. The medical records and radiological findings were reviewed. Surgical results including hormonal function and recurrence rates were analyzed according to extent of tumor invasion. Mean follow-up period was 19.1 months. Results : Tumors with suprasellar extension were removed totally in 54%, whereas total tumor removal was possible only in 38% with cavernous sinus invasion. Overall of recurrence rate was 14% and recurrence rate was 25% in suprasellar extension and 9% in cavernous sinus invasion. In cases of both suprasellar extension and cavernous sinus invasion, tumors that were treated by TSA and radiation showed recurrence rate of 7%, whereas those treated by surgery alone showed 28% of recurrence. Conclusion : Transsphenoidal approach is safe and useful operative method for pituitary adenoma and adjuvant therapy including radiation therapy is effective means to decrease the recurrence in cases of suprasellar extension or cavernous sinus invasion.
