Patients who have had arteriograms in our department performed by puncturing the axillary or brachial artery are being reviewed for complications relating to these procedures, as well as, the impact of the procedure on their length of stay in the interventional radiology area.  Access to arteries in the upper extremity has been known to have a higher complication rate than femoral artery access, however, access to the upper extremity is necessary in several cases relating to the patient’s clinical situation or to the specific procedure that is being performed.  Patient records will be reviewed along with their arteriogram films for data to include hematocrit, before and after, coagulation status and size of catheter used, and the procedure being performed.  These records will be tabulated for statistics and complication rates.
