Genomic modeling of atherosclerosis in peripheral arterial disease and its variant phenotype in patients with diabetes.

Microarrays can be used to discover candidate genes associated with peripheral arterial disease (PAD) and develop models that predict patient clinical status. We hypothesize that multiple phenotypes of PAD with distinct patterns of gene expression exist. We histologically characterized and extracted ribonucleic acid from 31 arterial samples collected from the lower extremities of patients undergoing amputation or free fibular grafting.

Superior vena cava perforation and cardiac tamponade after filter placement in the superior vena cava--a case report.

The purpose of this paper is to report the complication of perforation of the superior vena cava (SVC) leading to cardiac tamponade after the insertion of a Trapease IVC filter in the SVC position. A 29-year-old man was hit by motor vehicle and sustained numerous injuries including a left skull fracture, intracerebral hemorrhage, and left open tibial shaft fracture. During his hospitalization, he developed an extensive symptomatic right upper extremity deep venous thrombosis involving the brachial, axillary, subclavian, internal jugular, and brachiocephalic veins.
