[Long-term follow-up after acute myocardial infarct cause by non-arteriosclerotic spontaneous coronary artery dissection].

Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction, primarily in young women. The etiology of dissections is still under discussion. Possible factors are inflammation, changes of flow dynamics, and preexisting intima lesions. We report on two young women, 49 and 30 years of age, who suffered and acute anterior wall infarction. Coronary angiography confirmed diagnosis of spontaneous coronary artery dissection of the LAD in the acute an subacute phase of acute myocardial infarction. The patients suffered no further cardiac events at long-term follow-up of up to 9 years.

[New markings of central venous catheters, an improvement for localisation on x-ray pictures (author's transl)].

Despite the inweave of an X-ray positive thread the tip of a venous catheter is not always clearly delineated in the roentgenogram. The use of a new type of marking is considered to be constructive. The tip and further clearly identifiable equidistant markings along the length of the catheter are suggested. These facilitate an exact localisation of the catheter either directly or indirectly, and thus necessary corrections can be undertaken easily and exactly. Catheter fractures, embolisation of such fragments and extravenous placement of the catheter are immediately discernible. Furthermore we assume that X-ray dosage can be reduced and contrast medium accidents can be avoided.
