The distribution of portal veins within the liver in 30 Korean native cattle were observed. Vinylite solution was injected into portal veins of eighteen specimens for cast preparation. The angiography was prepared in twelve specimens by injecting 30% barium sulfate solution into portal veins, and then radiographed on a X-ray apparatus(Shimadzu 800MA 120Kvp). The results were summarized as follow: 1. The Vena portae was divided immediately upon entering the liver into a very short Truncus dexter venae portae($14.75{\pm}4.86$ : 6.9~23.1mm) and a long Truncus sinister venae portae($94.16{\pm}9.62$ : 110~150mm). 2. The Truncus sinister venae portae runs of first in the long axis of the liver from the Porta hepatis toward the left lobe. At the boundary between the quadrate and left lobes it bends sharply 50 to 80 degrees toward the Incisura ligamentum teretis, and after a course of 36. 5 to 54.mm between the quadrate and left lobes, ends abruptly. The Truncus sinister venae portae is divided for description into the Pars transversa, from the Porta hepatis to the flexure, and the Pars umbilicalis, from the flexure to the end. 3. The branches of Venae portae were Ramus ventralis lobi sinistri, Ramus intermedius lobi sinistri, Ramus dorsalis lobi sinistri, Ramus lobi quadratii, Ramus ventralis lobi dextri, Ramus intermedius lobi dextri, Ramus dorsalis lobi dextri, Rami processus caudatorum and Rami processus papillarum. 4. The Ramus intermedius lobi sinistri was arised from the left surface of the Pars umbilicalis, and was origined on the common trunk with Ramus dorsalis lobi sinistri(3 cases, 10%) or Ramus ventralis lobi sinistri(3 cases, 10%). 5. The Rami lobi quadratii consisted of the vein(15 cases, 50%) or two veins(15 cases, 50%), and was observed on the arched-shaped at 2 cases (6.6%) of the liver. 6. The Rami processus caudatorum consisted of one vein(28 cases, 93.3%) or two veins(2 cases, 6.6%). The former were formed common trunk with R, dorsalis lobi dextri(7 cases, 23.3%) or R. ventralis lobi dextri (2 cases, 6.6%). 7. The Rami processus papillarum were arised from the dorsal border of Pars transversa, and also gave off many small branches supplied papillary process of the caudate lobe. 8. The anastomosis on the branches of Vena portae was observed in the intralobar and interlobar areas. 9. The Truncus dexter venae portae and Truncus sinister venae were ramified many secondary branches that were radiated within the liver. 10. On the diaphragmatic surface, small vessels of the portal veins were observed, while there were big ones on the visceral surface. 11. The ramified angles at Ramus dorsalis lobi dextri, Rami processus papillarum, Ramus dorsalis lobi sinistri, Ramus intermedius lobi sinistri, Ramus ventralis lobi sinistri, Rami lobi quadratii, Rami processus caudatorum, Ramus ventralis lobi dextri and Ramus intermedius were 10~50, 70~110, 100~150, 140~170, 185~220, 270~330, 240~300, 270~320 and 340~10 degrees, respectively.

Infratentorial cerebral hemorrhage due to a direct carotid-cavernous fistula (CCF) is very rare. To our knowledge, only four such cases have been reported. Cerebellar hemorrhage due to a direct CCF has not been reported. We describe a 63-year-old female who presented with reduced consciousness 3 days after undergoing a maxillectomy for maxillary cancer. Computed tomography showed a cerebellar hemorrhage. Magnetic resonance angiography showed a left-sided direct CCF draining into the left petrosal and cerebellar veins through the left superior petrosal sinus (SPS). Her previous surgery had sacrificed the pterygoid plexus and facial vein. Increased blood flow and reduced drainage could have led to increased venous pressure in infratentorial veins, including the petrosal and cerebellar veins. The cavernous sinus has several drainage routes, but the SPS is one of the most important routes for infratentorial venous drainage. Stenosis or absence of the posterior segment of the SPS can also result in increased pressure in the cerebellar and pontine veins. We emphasize that a direct CCF with cortical venous reflux should be precisely evaluated to determine the hemodynamic status and venous drainage from the cavernous sinus.

Purpose: Mondor's disease is a rare benign condition which involves thrombophlebitis of the superficial veins of the breast and anterior chest wall after breast surgery, breast tissue biopsy, inflammatory reaction, breast cancer, trauma. The affected veins include the lateral thoracic, axillary veins, thoracoepigastric veins and superior epigastric veins. Methods: A 49-year-old woman presented to the outpatient department with complaints of the sudden appearance of a subcutaneous cord just under the skin at left lower lateral abdominal wall 1 month later of bilateral mastectomy due to both severe breast paraffinoma. The cord was initially red and tender and subsequently became a painless, tough, fibrous band that was accompanied by tension and skin retraction. Results: On ultrasonographic findings, palpable threadlike structures at both lateral superficial abdominal wall after bilateral mastectomy were noted. Superficial short elongated hypoechoic tubular structures were noted just under the skin at palpable lower lateral abdominal wall. It was compatible to Mondor's disease of thoracoepigastric vein. Conclusion: The increase in breast surgery will give rise to the increase in the frequency of Mondor's disease clinically. Mondor's disease can be diagnosed with clinical symptoms and image findings and the disease has proved to be benign and self-limited.

배경: 비록 경화요법이 정맥류를 치료하는데 확립된 방법일지라도 그 성공률에는 차이가 있다. 따라서 이 연구의 목적은 압박경화요법의 치료효과와 합병증을 평가하는데 있다. 대상 및 방법: 2000년 12월부터 2001년 9월까지 일차성 하지 정맥류 환자중 압박경화요법을 시행 받은 39명(50예의 하지)을 대상으로 하였다. 주사한 직후 정맥류의 경로를 따라서 탈지면롤을 댄 후, 다시 class II 압박스타킹을 신겼다. 환자는 치료효과와 합병증의 정도를 보기 위해서 시술후 5일, 1주, 2주, 6주에 평가되었다. 결과: 환자의 연령은 26세에서 66세까지로 평균 45.3세이었으며 여자 36명, 남자 3명이었다. 모든 환자에서 경화요법의 결과는 우수하였다. 50례의 하지 중 5례에서만 작은 합병증이 있었는데 2례의 혈관내 작은 응혈, 2례의 색소침착, 1례의 압박으로 인한 수포가 있었다. 이는 특별한 치료 없이 모두 회복되었다. 결론: 국소 압박도구로써 탈지면롤은 매우 손쉽고 효과적이며, 압박경화용법은 경제적 부담이 적고 안전하고 효과적인 치료법이다.

콩에 발생하는 불마름병은 주로 엽맥을 따라 병징이 형성되며, 이러한 병징의 형성에 대한 원인을 밝히고자 광학현미경 및 주사전자현미경으로 표면을 관찰하였다. 광학현미경 관찰에 의한 조직의 차이는 볼 수 없었으나 주사전자현미경으로 표면 관찰시, 잎 뒷면 미세한 엽모가 잎표면에 존재하였으며 엽맥 주위로는 엽모가 관찰되지 않았다. 세균은 엽맥 주위 엽모가 없는 부분에 주로 부착되어 있었고, 엽모가 있는 부분에서 세균은 관찰되지 않았다. 또한 잎에 불마름병균을 접종 후 표면 미생물을 배양시 엽맥주위에서 주로 세균이 검출되어 엽모의 존재가 불마름병균의 부착을 방해하여 엽맥주변으로 병징이 발현된 것으로 판단된다.

Background: Behçet disease is a chronic inflammatory disorder with a varying etiology. Herein, we report the involvement of peripheral veins in Behçet disease and discuss the treatment thereof. Methods: Thirty-four patients with venous involvement in vasculo-Behçet disease were retrospectively analyzed over 15 years. We reviewed the clinical manifestations, treatment choices, and complications of these patients. Results: Deep vein thrombosis (DVT) was observed in 24 patients (70.59%) and varicose veins in 19 (52.94%). Immunosuppressive treatment was administered to all patients due to the pathological feature of vein wall inflammation. In patients with DVT, anticoagulation therapy was also used, but post-thrombotic syndrome was observed in all patients along with chronic luminal changes. Eleven patients with isolated varicose veins underwent surgery; although symptoms and lesions recurred in half of these patients, no cases of secondary DVT occurred. Conclusion: When DVT was diagnosed in patients with Behçet disease, there was no cure for the lesions. Ultrasonographic abnormalities were observed in all patients, and post-thrombotic syndrome remained to varying degrees. In cases of isolated varicose veins in patients with Behçet disease, DVT did not occur after surgical treatment. If the activity of Behçet disease is controlled, surgical correction of varicose veins is preferable.
