We successful treated on case of cardiac catheterization pseudoaneurysm of femoral by color doppler ultrasound-guided compression technique. We consider that dolor doppler ultrasound-guided compression therapy is safe and effective first-line for catheterization-induced pseudoaneurysm.

The conventional non-invasive and invasive technique have limitations in evaluating cardiac prosthetic valves and artificial valves. We have used continuous wave Doppler echocardiography to evaluate 48 patients with tissue and mechanical mitral valves implanted within 4 months prior to examination. The results are as follows. 1) Of these patients, male are 28. The mean ages of male are 35.60 (yr) and female are 41.82. 2) The differences of peak and mean velocities of prosthetic acardiac valves between male and female are not significant, but the differences of valvular size between male and female are significant(male:31.00±1.30(mm), female:29.36±2.11, p<0.01). 3) The difference of size and flow velocities between mechanical (Edwards-Duromedics) and tissue(Ionescue-Shiley) valves are not significant, but the ages of patients with mechanical valves are significantly lower than tissue valves(mechanical valve; 34.05±11.28, tissue valve; 43.62±11.26, p<0.01). 4) The differences of flow velocities between mechanical and tissue valves, sizes of which are 31mm, are significant statistically (peak velocity; 130.15±24.59 vs 110.00±19.41, mean velocity; 74.49±23.14 vs 51.38±12.71, p<0.01). 5) The sizes of valves are larger, the peak and mean velocities are lower, but it is not significant statistically. The results indicated that Doppler echocardiography is a useful method for evaluating function of prosthetic valves.

To evaluate the relationship between coronary artery disease(CAD) and the various levels of lipid and lipoproteins, we performed coronary angiography to the patient, who were suspected coronary artery disease from January 1988 to August 1989. And compared it with normal control group. The number of control group were 41(21 men, 20 women), and the patient group were 52(42 men, 10 women). The age was not differ between two groups. The results were as follows; 1. In CAD group, the plasma concentration of total lipid, triglyceride, total cholesterol, phosphlipid, and TC/HDL ratio were significantly higher than in control group. But, though, the concentration of HDL was lower in CAD group, had no significant difference between two groups. 2. The severity of CAD were well correlated with total lipid, cholesterol, LDL, trigylceride, phospholipid, TC/HDL, LDL/HDL levels. HDL level didnt's show significant correlation with the degree of CAD. We concluded that total lipid, cholesterol, trigylceride TC/LDL ratio were valuable markers of CAD in Korean, but futhur studies of lipoproteiins and other risk factors in the large population will be recommended.

To study the pseudocholinesterase acticity and its clinical significance in patients with acute organophosphate poisoning, Authors checked the serum cholinesterase activity in 49 normal subjects and 31 acute organophosphate poisoned patients. The results were followings. 1. The mean pseudocholinesterase activity f normal subjects was 1271 IU/L in male and 1131 IU/L in female. The total mean cholinesterase activity was 1209/ IU/L. 2. The pseudocholinesterase activity of patients were significantly reduced compare to normal. 22 patients(73%) were below 10% of normal, 6 patients(20%) were between 10-20% of normal and only 2 patients (7%) were between 20-50% of normal. 3. As a whole there was more depressed cholinesterase activity in patients with comatous and drowsy mentality, but there was no statistically significant difference between three groups. 4. The pseudocholinesterase activity in patients with respiratory failure was more depressed than without respiratory failure, but there was no statistically significant difference between three groups. 4. The pseudocholinesterase activity in patients with respiratory failure was more depressed than without respiratory failure, but there was no statistically significant difference presented. 5. The mean arterial blood gas checked on arrival was pH 7.386, PaO?? 66mmHg, PaCO?? 38mmHg 02 Saturation 91%. There was noted no statistically significant correlation between pseudocholinesterase activity and these parameters. 6. The pseudocholinesterase activity on the 1st day of admission was 5.7% of normal and progressively increased during admission. On the 14th day of admission, the pseudocholinesterase activity was 35.5% of normal and it takes 20 days to reach 50% of normal. Authors concluded that serum cholinesterase activity of acute organonphosporus poisoned patients were markedly depressed and progressively increased during admission. As a whole the pseudocholine-sterase activity seemed to be related to the clinical findings but no statistically significant difference was found.
