Prosthetic Aneurysm in an Axillofemoral Dacron Bypass Graft

types of synthetic fibers. A number of publications have already appeared describing complications of graft dilation or rupture of prostheses secondary to yarn deterioration. 1-8 The following case report illustrates such yarn deterioration in an axillofemoral knitted Dacron graft. This case is reported to stress that patients bearing any type of vascular prosthesis should be observed throughout their lifetime for this complication.

A new approach in evaluating the hemodynamics of ischemic legs by mass spectrometry: a preliminary report.

Mass spectrometry has been used for continuous in vivo measurement of tissue, blood, and respiratory gases since Brantigan and his colleagues’ developed the nonthrombogenic diffusion membrane patterned after Grode’s method.’ To evaluate tissue perfusion, mass spectrometry has also been used to measure cerebral, myocardial, and skeletal muscle gas tensions, both experimentally and clinically.’-’ The hemodynamics of peripheral arterial disease have been elaborated by plethysmography, thermography, impedance and Doppler devices, and radioactive clearance. Angiography is widely u6!~;L’. to diagnose obliterative arterial diseases, but the information provided by angiograms is relatively limited.
