I just had rubber roofing installed on three one-story wings and two small porches with nearly flat roof surfaces. Sheets of a fiberboard-like material were laid down over the old roll roofing to cushion and protect the rubber.
Atherosclerotic Peripheral Vascular Disease. Introduction. The peripheral arteries include those branches of the aorta. supplying the upper and lower extremities and the abdominal. viscera. Most peripheral arterial occlusive disease is due to athero-. sclerosis, although other conditions such as fibromuscular dysplasia, muscular entrapment, cystic adventitial degeneration, and arteritis. may cause obstruction of the peripheral arteries.
In most cases of necrotizing sialometaplasia, the etiology is believed to be related to vascular ischemia. Cases are reported in which vascular compression is caused by a necrotic myocutaneous reconstruction flap, embolization from carotid endarterectomy, sickle cell anemia,Buerger disease,or Raynaud phenomenon.
