  • 혈관 내 재개통 인터벤션은 수술 후 정맥폐색에 있어 효과적인 치료 방법 중 하나이다. 간경유 또는 비장경유를 통한 접근을 흔히 시도하지만, 경피적 장간막 경유 접근 방법은 전향적인 접근이 가능한 장점이 있다. 본 증례는 수술 후 간문맥 이식편 폐색 환자에서 경피적 장간막 경유 접근법으로 성공적인 혈관 내 재개통을 보여준다.

  • The present study was carried out to evaluate the effect of Panax ginseng on the metabolism of nonprotein nitrogen compounds in rabbit blood. After rabbits were administered with ginseng powder orally for 30 days or with ginseng extract intraperitoneally for 10 days, the blood was collected from portal and ear vein to measure ammonia, urea, creatinine and nonprotein nitrogen. The blood ammonia level in ear vein of control rabbits was $87.0{\pm}5.1{\mu}g/100ml$ and was not significantly different from that of rabbits which were administered with ginseng powder orally or with ginseng extract intraperitoneally. But oral administration of ginseng powder produced a great decrease in ammonia level of portal vein from 1,392 to $704{\mu}g$ per 100ml, suggesting that intestinal ammonia production is suppressed by ginseng powder due to its antimicrobial activity. While there was no significant difference between the control and the rabbits which were administered with ginseng extract intraperitoneally. Ginseng administration had no effect on the creatinine level in blood from ear and portal vein, except the intraperitoneal injection of ginseng extract. It slightly lowered the creatinine level only in ear vein blood. The values of urea and nonprotein nitrogen were net affected by the administration of ginseng.

  • Purpose: The purpose of current study is to evaluate the response of the patients with portal vein thrombosis (PVT) or hepatic vein thrombosis (HVT) in hepatocellular carcinoma (HCC) treated with three-dimensional conformal radiation therapy (3D-CRT). In addition, survival of patients and potential prognostic factors of the survival was evaluated. Materials and Methods: Forty-seven patients with PVT or HVT in HCC, referred to our department for radiotherapy, were retrospectively reviewed. For 3D-CRT plans, a gross tumor volume (GTV) was defined as a hypodense filling defect area in the portal vein (PV) or hepatic vein (HV). Survival of patients, and response to radiation therapy (RT) were analyzed. Potential prognostic factors for survival and response to RT were evaluated. Results: The median survival time of 47 patients was 8 months, with 1-year survival rate of 15% and response rate of 40%. Changes in Child-Pugh score, response to RT, Eastern cooperative oncology group performance status (ECOG PS), hepatitis C antibody (HCVAb) positivity, and additional post RT treatment were statistically significant prognostic factors for survival in univariate analysis (p = 0.000, p = 0.018, p = 0.000, p = 0.013, and p = 0.047, respectively). Of these factors, changes in Child-Pugh score, and response to RT were significant for patients' prognosis in multivariate analysis (p = 0.001 and p = 0.035, respectively). Conclusion: RT could constitute a reasonable treatment option for patients with PVT or HVT in HCC with acceptable toxicity. Changes in Child-Pugh score, and response to RT were statistically significant factors of survival of patients.

  • Objective: To explore the effect of portal vein chemotherapy on liver metastasis after surgical resection of colorectal cancer. Methods: Patients fulfilling the eligibility criteria were assigned to receive either surgery plus 1-week continuous infusion of 5-FU (study group) or surgery alone (observational group). Patients in the study group received portal vein chemotherapy, whereby 5-FU (1000 mg/d) and heparin (5000 IU/d) infusion was initiated from the day of surgery and lasted for 7 consecutive days. Liver metastasis was monitored during five years follow-up postoperatively. Results: Sixty four patients were recruited and assigned to the study group (12 with colon and 20 with rectal cancer) or the control group (10 with colon and 22 with rectal cancer). Liver metastasis rate was 12.5% in study and 25.0% in observational group, the difference being significant (P<0.01). Conclusion: Portal vein chemotherapy could be an effective treatment in preventing liver metastasis after surgical resection of colorectal cancer.

  • Recently we experienced a case of the portal hypertension, extrahepatlc origin in the National Medical Center, Seoul. The case was a male aged 19 who was undergone the elective splenorenal shunt with splenectomy 9 years ago and emergency ligation of the coronary vein because of recurred variceal rupture 6 years later and had recurring esophageal varices with bleeding this time.At the age of 10 he had been occasionally suffering from nasal bleeding and visited to our Pediatric department, when there was encountered for the first time the splenomegaly, esophageal varices in the lower third esophagus on the esophagogram, and stenosis and kinking of the portal vein with rich collateral circulation on the splenoportography without hepatic functional impairment.The elective splenorenal shunt with splenectomy was undergone under the diagnosis of portal hypertension due to congenital anomaly of the portal vein and postoperatlvely no troubles had been obtained until postoperative 1st attack of massive hematemesis due to esophagenl variceal rupture recurred about 6 years later which was confirmed by control esophagogram and it was resulted by stenosis of previous anastomotic site of the splenorenal shunt.Then emergency ligation of the coronary vein was only made for bleeding control and no episodes of hematemesis had been encountered thereafter until April 1972 about 3 years after the 2nd operation, when hematemesis recurred again. In this time, recurring esophageal varices were noted in the lower third esophagus on the control esophagogram and he was employed side to end mesocaval shunt as the final step of portal decompression,and following results were obtained. 1] No postoperatlve troubles as leg edema or pain: Postoperatively leg elevation and elastic bandage on the both legs were employed until discharge. 2] During operation the portal pressure was 300 mm $H_2O$ and immediately lowered to 170 mm $H_2O$ after shunt.

  • Portal blood flow was measured with pulsed doppler ultrasound in thirty normal dogs. In normal dogs, the average portal blood flow velocity was $17.03{\pm}1.75cm/sec$ and the average portal blood flow was $41.59{\pm}10.10ml/min/kg$. The incident angle between the doppler beam and the portal vein averaged $65^{\circ}$. The average portal vein sectional area was $0.41{\pm}0.14cm^2$. The Congestion index was $0.0245{\pm}0.0081cm{\cdot}sec$. Conclusively, the spectral doppler ultrasonography was quick, non-invasive and simple diagnostic method in circulatory disorders of liver.

  • Despite recent advancements in the diagnosis and treatment of pancreatic cancer, clinical results remain dismal. Furthermore, there are no reliable biomarkers or alternatives beyond carbohydrate antigen 19-9. Circulating tumor cells (CTCs) may be a potential biomarker, but their therapeutic application is constrained by their rarity in peripheral venous blood. Theoretically, the portal vein can be a more appropriate location for the detection of CTCs, because the first venous drainage of pancreatic cancer is portal circulation. According to several studies, the number and detection rate of CTCs may be higher in the portal blood than in the peripheral blood. CTC counts in the portal blood are strongly correlated with several prognostic parameters such as hepatic metastasis, recurrence after surgery, and survival. The phenotypic and genotypic properties analyzed in the captured portal CTCs can assist us to comprehend tumor heterogeneity and predicting the prognosis of pancreatic cancer. The investigations to date are limited by small sample sizes and varied CTC detection techniques. Therefore, a large number of prospective studies are required to confirm portal CTCs as a valid biomarker in pancreatic cancer.

  • 64세 남성이 2미터 높이에서 낙상한 이후 심한 우측 옆구리 통증으로 내원하였다. 시행한 조영증강 전산화단층촬영에서 우측 혈흉과 다수의 우측 갈비뼈 골절 및 우측 장골의 골절 소견이 있었다. 또한 간 주변에 혈종이 있었으나, 간실질 외상 소견은 보이지 않았다. 먼저 시행된 수술 중, 간문에서 지혈되지 않는 지속적인 출혈이 관찰되었다. 이에 대한 진단을 위해 인터벤션 시술이 시행되었고, 최초 간동맥조영술에서는 출혈 소견이 보이지 않았다. 이어서 시행한 조영증강 전산화단층촬영에서 좌측 복부의 조영제혈관바깥유출이 보였는데, 이는, 경피경간문맥조영술에서 좌측 문맥의 출혈로 확인되었다. 이 지점에 접착제 색전술을 시행했으나, 환자는 끝내 사망하였다. 이 증례를 통해 복부 외상환자 평가에서 간동맥조영술이 정상이라도 간문맥 손상의 가능성을 고려해야 한다는 것과 복부에서도 반충손상기전에 의한 손상이 가능하다는 것을 확인하였다.

  • 좌측 단독 문맥고혈압은 비장 정맥이 폐쇄되어 생기는 드문 임상 질환이다. 비장 정맥의 혈전증 혹은 외부 압박으로 인해 근위부 비장정맥의 고혈압이 발생하게 되며, 비장의 혈류는 짧은 위 정맥, 관상정맥, 위대망정맥 같은 측부혈관을 통하여 상장간막 정맥 혹은 문맥으로 흘러가게 된다. 위장관 출혈을 유발하는 좌측 단독 문맥고혈압에는 개복 비장절제술이 첫 번째 치료방법으로 추천된다. 하지만 중재시술을 통한 치료가 수술적 교정을 원치 않는 환자들에게는 임상적으로 유용한 치료 선택지가 될 수 있다. 본문에서는 위정맥류 출혈을 가진 좌측 문맥 고혈압에 대한 두 개의 증례를 다루고자 한다.
