ABSTRACT
The prevalence of obstructive arterial disease is between 3.5 and 12.1% in 60 aged populations. It's a current disease which has a pernicious influence in quality of life. Management of patients with peripheral arterial occlusive disease has to be planned in the context of natural history, epidemiology, and apparent risk factors that predict deterioration. The purpose of this review is to take stock of the consensus and the controversies about terminology, epidemiology, diagnosis and management of peripheral arterial occlusive disease.

Chronic contained rupture of abdominal aortic aneurysm is a rare event which can cause diagnostic difficulties. It can present as a chronic back pain and the delayed diagnosis and delayed surgical repair may compromise the final results. The outcome of urgent repair of a chronic contained leak is equivalent to that of elective aneurysm repair. We report a case of contained rupture of a small abdominal aortic aneurysm with delayed diagnosis, evaluated by computed tomography showing a beginning erosion of the lumbar vertebral body. The patient was operated on within 24 hours on admission with uneventful surgical outcome.

OBJECTIVES: To assess the effet of cryopreservation on the structural and functional properties of venous and arterial human allografts. MATERIALS AND METHODS: Segments of arteries and veins harvested from multiorgan donors were divided into 3 groups: fresh-control tested for 24 hours after harvesting, frozen directly at -80 degrees C and frozen gradually (progressive freezing technique) and preserved in liquid nitrogen at -196 degrees C degree. The 2 cryopreserved groups of segments were allowed in two different cryoprotectant solutions (M1 and M2) containing both dimethyl sulphoxide (10%), RPMI 1640 for the first and M 199 for the second. Rapid thawing was done at regular intervals over 4 months and the allografts were processed for biomechanical, ultrastructural, morphological and immunohistochemical analysis. RESULTS: Cell damage was less intense in the specimens conserved in M1 solution and by progressive freezing technique especially for smooth muscle cells and endothelial cells which remained preserved until 12 weeks. CONCLUSION: Cryopreservation in both the solutions employed induce changes in the morphology of arterial wall. Better results were obtained with RPMI 1640 associated with progressive freezing.
