[Isolated interrupted aortic arch].

Interrupted aortic arch is rarely presented as an entirely isolated lesion (in childhood or young adult life) in a manner similar to classical coarctation and in association with obvious collateral circulation. We present a 24-year old male with arterial hypertension of the upper body part caused by interrupted aortic arch. In this patient the femoral pulses were reduced, collateral circulation was palpable intercostally.

[Pathologic morphology and clinical significance of the anomalous origin of the left circumflex coronary artery from the right coronary artery. General review and autopsy analysis of 30 cases].

After an extensive analysis of the world literature (121 references), beginning from the first reported case by Antopol and Kugel, 1933, the general review of the problem stressed especially the following morphologic characteristics and clinical significance of the anomalous origin of the left circumflex coronary artery (LCxA) from the right coronary artery (RCA): The place of the anomalous origin of LCxA from RCA among all other variations and anomalies of LCxA. The anatomical and topographical characteristics of LCxA originating from RCA in normal heart as well as in congenital heart diseases--CHD (especially complete transposition of great arteries--TGA). The formal genesis of LCxA from RCA according to original new Ogden's theory, taking into account the dual origin of the coronary arteries and the peritruncal angioblastic ring that surrounds the developing aorta and pulmonary artery.

Pulmonary artery pressure in rats with hereditary platelet function defect.

Pulmonary vasoactivity of several biochemical components produced or stored in platelet was the justification for the study of pulmonary artery pressure in fawn-hooded rats (FHR) with hereditary platelet storage pool deficiency. Anesthetized (pentobarbital 35 mg kg-1 i.p.

Correlation of clinical diagnoses with autopsy findings: a retrospective study of 2,145 consecutive autopsies.

The protocols of 2,145 autopsies were retrospectively reviewed and the findings compared with the clinical diagnoses. A sudden decline in the autopsy rate that occurred during the period studied was followed by a highly statistically significant difference in clinical accuracy (P less than 0.01), in favor of the predecline period.
