ABSTRACT
We report a case of migration of a surgical localization wire from the breast to the abdomen. A 41-year-old female underwent presurgical needle localization of a deep-sited left-sided breast lesion. Migration of the localization wire in the chest wall occurred during the procedure documented by imaging. Computed tomography (CT) examination showed no evidence of the wire in the left lower lung field, no peritoneal free fluid, active bleeding, or abnormalities of abdominal organ, but a metallic-density representing the localization wire was seen for a length of 13 cm from the right diaphragmatic crus to the right psoas muscle, close to the inferior vena cava. A following CT examination showed the wire partially outside the inferior vena cava and partially inside the right iliac vein. The wire was successfully taken out by an angiographic interventional procedure.

The inhibitory effect on platelet function induced by several radiographic contrast media is still poorly understood. In this study platelet abnormalities caused by in vitro addition of ioglicinic acid, a new ionic contrast medium, were evaluated. The appearance of several granules similar to dense bodies associated with shape change and internal reorganization were detected by electron microscopy techniques. A functional study revealed a marked decrease in the aggregating response of platelets to adenosine diphosphate and calcium ionophore A23187, while aggregation in response to collagen was completely normal. It is suggested that ioglicinic acid induces platelet abnormalities related to the effect on calcium movements and that studies with this contrast medium may help the understanding of some basic events of platelet activation.

It has long been supposed that histamine plays an intemediary rôle in pulmonary hypertension due to hypoxia, though no firm evidence has been collected. Lung and aortic pressure and the blood histamine content in the aorta, pulmonary artery, vena cava inferior, and suprahepatic veins were therefore measured in anaesthetised dogs breathing ambient air, and after 5' administration of a gas mixture containing 8% O2. Lung pressure rose significantly and aortic pressure changed only slightly. Histamine values, however, rose significantly in the pulmonary artery and were unchanged in the aorta after the hypoxic stimulus. In addition, concentrations were higher in the vena cava and unchanged in the suprahepatic veins. These results indicate that histamine is released from skeletal muscle and electively taken up by lung tissue during hypoxia. Its rôle is certainly important, but further elucidation must await the performance of other studies using drugs that selectively block its release from the muscle district.
