Discussion and management of late failures in reconstructive procedures involving the abdominal aorta.

Review of fifty-eight late failures of 326 procedures performed for revascularization of the abdominal aorta over the past six years showed a low overall operative mortality of 9 per cent. Secondary vascular procedures directed at the aorta itself or at its graft substitute proved more effective in relieving symptoms and restoring flow than did secondary procedures directed at more distal problems in the lower extremities. The aortofemoral graft in conjunction with profundaplasty proved to be the most effective means of restoring flow to the lower extermity after graft occlusion in a previous aortoiliac or aortofemoral graft.

Reduction of early occlusions in the high risk peripheral saphenous vein graft.

Early thrombosis of saphenous vein grafts can only reduce long-term patency. There exists a high risk category of patients who can be identified preoperatively where early failure is increased above the 10-20% which is attributed to technical errors. A venous side-arm indwelling catheter offers a safe means of reducing early thrombosis, promptly diagnosing the occlusion when it does occur, and more clearly delineating a course of corrective action. The venous side-arm catheter provides a means by which the vascular bed at highest risk may be regionally anticoagulated while allowing systemic clotting times to remain near normal. In addition, vasoactive drugs may be infused directly into the arterial tree and perhaps most importantly, rapid and atraumatic arteriograms can be obtained postoperatively at the bedside for evaluation of questionable perfusion. Regional heparinization and postoperative arterigraphy by means to the side-branch catheter technique was used in twelve patients who otherwise had an expected occlusion rate of 75% or more with an actual early occlusion incidence of zero.

Cerebro-hepato-renal syndrome. Report of a case with histochemical and ultrastructural observations.

A new case of the cerebro-hepato-renal syndrome is being reported. The neuropathologic changes consisted of developmental abnormalities of cerebral and cerebellar cortex and of the inferior olives. In addition, there were metabolic changes in the central nervous system, indicated by an accumulation of lipid within histiocytes of free in gray and white matter, deficiency in myelination and gliosis of the white matter, and marked proliferation of protoplasmic astrocytes in the gray matter. A unique feature of this case was the presence of numerous clusters of lipid-filled macrophages and occasional cholesterol crystals in the molecular layer of the cerebellum. The histochemical reactions and ultrastructural appearances of the lipid deposits are suggestive of accumulation of several different types of lipids.
