배경: 수술 전 크레아티닌이 상승된 환자에서 심폐기를 이용한 관상동맥 우회술은 수술 후 사망률과 이환율이 증가라는 위험을 가지고 있다. 저자들은 최근에 수술 전 크레아티닌 치가 상승된 환자에서 신장기능의 변화를 조사하고 그에 대한 적절한 처치를 알아보았다. 대상 및 방법: 최근 심폐기를 이용하여 관상동맥 우회술을 한 74예 중 수술 전 일주일 이내에 1.5 mg/dL이상의 혈청 크레아티닌치를 가진 환자 11예를 대상으로 분석하였다. 이 중 크레아티닌 치가 2.0 mg/dL이상인 환자가 7예였고 그중 3예는 수술 전 혈액 투석을 받고 있는 환자였다 후자의 3예에서는 수술전날에 혈액투석을 하였다. 혈액투석을 받던 환자나 수술 후 급성신부전이 발생한 환자에서는 체액량 및 크레아티닌의 조절을 위해 수술 직후 복막투석을 시작하였다 결과: 관상동맥 우회술을 받은 모든 환자에서 수술 전보다 수술 후 크레아티닌치의 상승을 보였으며 퇴원 시에 수술 전 크레아티닌치로 회복되었다. 2.0mg/dL 이상의 크레아티닌치를 가진 환자 4예 중 2예와 혈액투석을 받던 3예에서는 수술 후 복막투석만으로 체액량과 크레아티닌치를 조절할 수 있었고 혈청 전해질치도 유지할 수 있었다 결론: 관상동맥우회술 후 일시적으로 크레아티닌치가 상승하며, 급성신부전이 발생한 환자나 수술 전 혈액투석을 받던 환자에서는 수술 후 복막투석만으로도 체액 량과 크레아티닌치의 조절이 가능하였다.

Objective: We aimed to investigate whether repeated intravascular administration of iodinated contrast media (ICM) or gadolinium-based contrast agents (GBCAs) within a short interval was associated with an increased risk of post-contrast acute kidney injury (PC-AKI). Materials and Methods: This retrospective study included 300 patients (mean age ± standard deviation, 68.5 ± 8.1 years; 131 male and 169 female) who had undergone at least one ICM-enhanced perfusion brain CT scan, had their baseline and follow-up serum creatinine levels available, and had not undergone additional contrast-enhanced examinations 72 hours before and after a time window of interest were included. The study population was divided into three groups: single-dose group and groups of patients who had received multiple contrast administrations in the time window of interest with the minimum contrast repeat interval either within 4 hours (0-4-hour group) or between 4 to 48 hours (4-48-hour group). Multivariable logistic regression analysis was conducted to evaluate the association between AKI and repeated ICM administrations. A similar supplementary analysis was performed including both ICM and GBCA. Results: When ICM was only considered ignoring GBCA, among 300 patients, 207 patients received a single dose of ICM, 58 had repeated doses within 4 hours (0-4-hour group), and 35 patients had repeated doses between 4 to 48 hours (4-48-hour group). Most patients (> 95%) had a baseline estimated glomerular filtration rate (eGFR) of ≥ 30 mL/min/1.73 m². AKI occurred in 7.2%, 13.8%, and 8.6% of patients in the single-dose, 0-4-hour, and 4-48-hour groups, respectively. In the 0-4-hour and 4-48-hour groups, additional exposure to ICM was not associated with AKI after adjusting for comorbidities and nephrotoxic drugs (all p values > 0.05). Conclusion: Repeated intravascular administrations of ICM within a short interval did not increase the risk of AKI in our study patients suspected of acute stroke with a baseline eGFR of ≥ 30 mL/min/1.73 m².

The rupture of a renal artery aneurysm is a rare disease that is difficult to diagnose. Although we usually consider the appropriate treatment to be open laparotomy with aortic aneurysm surgery or stenting with graft insertion through intravascular intervention, thus far, there is no general consensus on the treatment protocol for renal artery aneurysm. Notably, ruptured renal artery aneurysm is a true critical emergency that may result in a fatal outcome. We are reporting two renal artery aneurysm patients who had ruptured and underwent emergency laparotomy.

Based on the technical innovation of the recent communication system technologies, systems are linked by the worldwide network. We introduce some examples of the multimedia network systems. Especially, we introduce our recent attempt to realize the multimedia tele-surgery system using high speed optical fiber network. At first, we shows the technical problems of the multimedia tele-surgery. We applied this idea to the intravascular neurosurgery. System configuration for the prototype experiments and experimental results are shown.

A preterm newborn affected by congenital syphilis, born to mother not treated during pregnancy is described. The clinical picture was characterized by respiratory distress, cutaneous manifestations, massive hepatosplenomegaly, severe anemia, thrombocytopenia, disseminated intravascular coagulation syndrome and hypoalbuminemia. The patient was treated with daily injections of 190,500 units of crystalline penicillin G for 14 days. Premature infants with these symptoms and signs should be evaluated for congenital syphilis.

Objectives : We aimed to identify the effects of Heechum-san(HCS) On the thrombosis. Methods : We measured the protective effects of HCS on pulmonary thromboembolism induced by collagen and epinephrine, intravascular coagulation induced by dextran. Results : HCS showed a effective inhibition on coagulation of platelets induced by ADP or epinephrine. HCS showed survival rate of 14.28% on pulmonary thrombo- embolism caused by collagen and epinephrine. On the measure of the blood flow rate induced by the thrombus, in vivo HCS accelerated the blood flow rate. Conclusions : HCS has antithrombotic effects.

In previous studies, high fever, inappentence, increased respiratory rate, muscle tremors, anemia, jaundice, loss of weight hemoglobinenuria and hemoglobinuria were found in dogs infected intraerythrocytic protzoan parasites of the gennus Babesia. These changes were mainly caused by the intravascular hemolysis. In this study, a Pit Bull Terrier, which was infected by babesia, was investigated clinical signs and patterms of blood. The findings from this study indicated that dog with severs clinical signs shown erythropenia, lymphocytophilia, neutropenia, thrombocytopenia and eosinpenia. Furthermore, it presenter low level of hemglobin and hematocrit. However MCV, MCH and MCHC did not decreased as compare to normal dogs.
