The surgical treatment of aneurysms of the abdominal aorta with resection and grafting: review of 12 cases

1. An aneurysm of the abdominal aorta is a lesion which is a constant threat to a patients life because of the danger of rupture and exsanguination. The policy of "watchful waiting" is not to be commended in these cases. Resection of the aneurysm with insertion of a graft is the curative procedure for this condition2. The diagnosis, the selection of patients, and the surgical procedure are discussed3. Twelve cases are reviewed. Although the interval of this study has not been long enough to make definite conclusions, the results, as judged by the period of survival and relief of symptoms, appear to justify the use of this surgical procedure.

A new method of treatment of experimental uremia in dogs

The study described the use of human placenta as a dialyzing medium. This is a preliminary reportThe subject was a dog legated to produced uremia. A freshly delivered placenta was obtained. The two arteries and the vein of the umbilical cord were cannulated separately using glass cannules. The femoral vessels of the dog were exposed and cannulated on both sides. The cannulated vessels of the dog and the placent were connected to establish a closed circulation, such that the dogs blood flowed from the femoral arteries to the umbilical arteries through the placenta to the umbilical vein, then back to the femoral vein of the dog and its general circulationThe establishment of circulation through the placenta was satisfactory. The NPN and creatinine levels were determined and recorded.(Author)
