1029: PARTIAL ANOMALOUS PULMONARY VENOUS CONNECTION: A BENIGN CAUSE OF OXYGEN-RICH CENTRAL VENOUS BLOOD

Fifty-three central venous catheters were followed up by radiography or direct observation during open-heart surgery. Forty of these were satisfactorily positioned for recording central venous pressure or for sampling central venous blood. Radiography showed that the catheter tip was in an unsatisfactory position in 21 per cent of cases. It is recommended that radiographic confirmation of the site of the catheter tip be obtained as a routine and if necessary the catheter can be re-positioned and another radiograph taken.

Abstract 1. Megakaryocytes were demonstrated in central venous blood of each of 23 patients who underwent cardiac catheterization. Cell counts ranged from 0.7 to 5.9 megakaryocytes per ml. of blood; the equivalent of one-third of these cells were considered to contain a full complement of cytoplasm. It has become evident that megakaryocytes are normal constituents of blood. 2. In an attempt to quantify megakaryocyte migration from the bone marrow it was calculated that from 20-50 per cent of the mature megakaryocyte population enters the blood and ultimately reaches the lungs. The possibility that all megakaryocytes migrate from the marrow is not precluded with certainty by these studies. 3. It was estimated that from 7-17 per cent of the body’s platelets are released in the pulmonary capillaries. If all megakaryocytes migrate from the bone marrow, then as much as 33 per cent of the platelet population is delivered to the blood in the lungs.
