We practice in a community hospital, where I am a vascular surgeon/co-director of vascular lab.

We do not offer after hours studies. Our advice is to hospitalize on heparin overnite those who are at the most apparent risk, and schedule outpaitent a.m. scans for those at low risk. The introduction of low molecular weight heparin helps. Now outpatients can be treated with LMWH until a scan is done.
