Bilateral renal artery thrombotic occlusion: a unique complication following removal of a transthoracic intraaortic balloon.

An intraaortic balloon pump (IABP) was inserted through the ascending aorta during a coronary artery bypass operation. Five days later, after removal of the IABP and ligation of the end-to-side Dacron graft, the patient became acutely anuric. Abdominal aortography demonstrated a large "trapeze-shaped" thrombus which occluded both renal arteries. Following thrombectomy the patient recovered, with eventual return of renal function to the preoperative state.

Experimental renal infection: acute and chronic studies of histology and function.

Experimental renal infections have resulted in histologic lesions of acute and chronic pyelonephritis, but in most studies the urinary tract has been "traumatized" to induce persistent infection. Sequential functional alterations have been measured infrequently. The present studies were designed to separate the functional and histological changes caused by high pressure sterile reflux from reflux with pathogenic organisms. Reproducible disruption of the pelvic epithelium with extravasation of solution into the parenchyma and vasculature occurred with reflux of 2.0 ml of solution but not with 1.0 ml. Reflux with 2.0 ml of sterile broth failed to cause permanent histologic changes, but reflux with broth containing organisms resulted in minor inflammatory changes. There was no decrease in renal function in either group. In long-term studies, no histologic changes in the cortex or medulla were noted 21 weeks after reflux of 1.0 ml of broth containing organisms; however, there was failure of functional maturation in the infected animals commensurate with their growth, as compared to the shams and controls (P = 0.03). Sterile reflux did not cause cortical scars or changes in renal function, but persistent parenchymal infection was associated with arrest of functional growth.

Mitral valve replacement: a comparison of two prostheses.

Between November, 1965 and June, 1970, 175 patients underwent mitral valve replacement with the Smeloff-Cutter prosthesis (109 patients) or the toroidal valve (66 patients). The early mortality for patients with a toroidal mitral prosthesis was 18.2 percent (12 patients) and the late mortality 34.8 percent (23 patients). Among patients in whom Smeloff-Cutter mitral valves were inserted, the early mortality was 15.6 percent (17 patients) and the late mortality 23.9 percent (26 patients). During a follow-up period extending at least five years, thromboembolic complications occurred in 25.9 percent (14) of patients with toroidal valves and 7.6 percent (7) of patients with Smeloff-Cutter valves. Reoperation was necessary because of thrombosis of the prosthesis in seven patients with toroidal valves and two patients with Smeloff-Cutter valves. The incidence of endocarditis was the same in both groups. In this study, the Smeloff-Cutter mitral prosthesis proved to be superior to the toroidal valve because of a lower incidence of thromboembolism.
