Intrahepatic spontaneous portosystemic venous shunt: value of color and power Doppler sonography.

Spontaneous portosystemic venous shunts (SPVSs) within the hepatic parenchyma are rare. Fewer than 50 cases have been reported, and most of them were diagnosed by angiography. We present a case of SPVS diagnosed by color Doppler sonography in a 5-year-old boy admitted for bleeding due to rupture of esophageal varices. Conventional color and power Doppler sonography as well as CT showed a large shunt between the posterior branch of the right portal vein and the inferior vena cava. We believe that accurate diagnosis and follow-up of SPVS can be done with color Doppler sonography without resorting to angiography.

Primary coronary angioplasty and stent implantation in acute myocardial infarction. Comparative analysis of the in-hospital results in the CENIC/SBHCI registry. National Center of Cardiovascular Interventions members.

OBJECTIVE: Comparative analysis of the in-hospital results after primary implantation of stents or coronary balloon angioplasty in patients with acute myocardial infarction (MI). METHODS: CENIC (National Center of Cardiovascular Interventions) gathered data on 3, 924 patients undergoing coronary angioplasty (in the primary form, without the previous use of thrombolytic agents) in the first 24 hours after a MI, during the period of 1996-1998. From these 3,924 patients, 1,337 (34%) underwent stent implantation. We analyzed the success of the procedure and the occurrence of adverse cardiac events. RESULTS: In patients undergoing stent implantation there were more males (77% vs 69%, p=0.001), previous by pass surgery (6. 3% vs. 4.5%, p=0.01), anterior MI and stent implantation in left descending artery (55% vs. 48% vs. p=0.009), and saphenous vein bypass grafts (3.3% vs. 1.9%). the procedure was more succesful in the group of stents (97% vs. 84%, p=0.001) and reinfarction rate (2. 5 vs. 4%, p=0.002). The need for emergency revascularization was similar (1% vs. 1.1%, NS). Total in-hospital mortality was lower in stent group (3.4% vs. 7. 2%, p=0.0001) and this effect was in patients Killip class III/V (19.5% vs. 32.5%, p= 0.002) because there was no difference in patients class I/II (1.7% vs. 2.8%, p=0. 9). CONCLUSION: Primary stent implantation in acute myocardial infarction showed better early results than balloon angioplasty alome.

[Subcapsular hematoma complicating acute pyelonephritis].

Spontaneous subcapsular renal hematoma is rare and essentially associated with malignant, or benign tumor vascular diseases, inflammatory processes. In few cases, no cause was detected. We observed one additional case in a diabetic women. She presented fever, and bilateral flank pain. Ultrasonography showed bilateral subcapsular hematoma. Computed tomography confirmed these findings and demonstrated multiple area of acute focal pyelonephritis.

[Coronary angioplasty in octogenarians].

PURPOSE: To evaluate the indications, results and follow-up of patients with 80 years old and over, who had undergone percutaneous transluminal coronary angioplasty (PTCA). METHODS: From July 1987 through July 1990, 36 patients, 80 years of age and over, had PTCA as an alternative method to treat coronary artery disease. Their age ranged from 80 to 85 (mean = 83) years. Twenty five were male. Significative obstruction was considered when 70% or more of the internal diameter was stenosed. Satisfactory results were achieved when reduction of 50% or more of the coronary artery obstruction was obtained. RESULTS: In 34 of 36 patients (94.4%), PTCA was successfully performed. Forty four of 46 coronary arteries were successfully dilated. One patient had acute coronary occlusion with acute myocardial infarction treated clinically. There were no emergency surgeries or early deaths. Clinical follow-up was obtained in 15 of the 34 patients. Four had repeated coronary arteriography (at 1, 3, 6 and 12 months after primary PTCA) due to angina. Two of them had restenosis and were successfully redilated (the patients restudied at 3 and 6 months, respectively). Within a mean clinical follow-up period of 9.6 (ranging from 1 from 21) months the following features were observed: two of 15 patients (13.3%) had acute myocardial infarction and were clinically followed; late death occurred in 3 patients (20%) with only one related to cardiac events. Survival has been observed in 12 of these 15 patients (80%). CONCLUSION: PTCA represents an alternative, safe and effective invasive procedure to treat octogenarians with coronary artery disease.

The treatment of Friedreich's ataxia with amantadine hydrochloride.

Amantadine hydrochloride (AH) was orally administered to 16 patients with Friedreich's ataxia. We evaluated patient response with the functional ataxia scoring scale and calculated a total disability score. The mean percent improvement of the total disability score was 29.5%; for ambulatory patients alone it was 45.5%. No significant side effects were encountered. AH appears to be a safe and effective symptomatic treatment of Friedreich's ataxia.

[A theoretical analysis of systemic arterial blood pressure of mammals (author's transl)].

The theoretical reduced exponent b calculated for the arterial pressure, in accordance with Huxley's alometric equation, is 0; however the experimental value has shown different figures. In this paper it is proposed that systemic arterial pressure with exponent zero is in accordance with that of those arteries found at a greater distance of the heart but above cardiac level. We postulate that the cerebral arteries have an experimental exponent b = 0. We have calculated this exponent for the cephalic arterial pressure (arterial pressure at cardiac level minus hydrostatic pressure for cephalic level). With this correction, we have found a better correlation between experimental and theoretical figures in accordance with the theory of biological similarities.
