ABSTRACT
A retrospective study of 82 cases of peripheral vascular occlusive disease examined by retrograde femoral arteriography with a catheter needle technique showed a 6% incidence of retrograde arterial wall dissection involving the iliac arteries and the aorta. In one patient, the dissection re-entered the abdominal aorta near the renal arteries, producing an iatrogenic chronic dissection. The others did not demonstrate any permanent side effects. In 1974, in view of the appreciable risk in the use of a catheter needle, the technique was changed to percutaneous femoral catheterization of the abdominal aorta using a catheter with multiple side holes. No further cases of iatrogenic aortic dissection were observed. A veriety of mechanisms may have been responsible for the dissections.

Postmortem examination of a child with osteodysplastia (Melnick-Needles syndrome) showed peculiar fibro-osseous tissue in the marrow cavity, with areas of bone constriction but no abnormality of endochondral ossification. Pectus excavatum and scalloping of the vertebral bodies were also present.

Serial erect roentgenograms of the gallbladder during oral cholecystography were taken in 50 patients before and after a fatty meal. In the presence of good opacification, layering of opaque and nonopaque bile was noted in most cases 2 hours after the fatty meal. The degree of layering was related to the extent of gallbladder contraction produced by the fatty meal and the degree to which the gallbladder refilled by the inflow of nonopaque liver bile. The layering phenomenon thus appears to be a manifestation of a normally functioning gallbladder and occurs when the gallbladder refills with fresh nonopaque bile.

This is a case report of a patient with a variant of idiopathic intestinal pseudo-obstruction (IIPO). The patient, a 53-year old female with polycystic kidney disease, had intermittent episodes of intestinal distention with megaduodenum and megasigmoid noted at roentgen study and postmortem examination. The etiology of this abnormality is unclear and no significant changes in the innervation of the bowel were noted on gross or histologic study.
