Background:
Vascular surgeons can offer patients with arterial and venous disorders a multitude of endovascular and surgical options. Computed tomographic angiography (CTA) has the potential to allow the development of an effective interventional strategy without subjecting patients to invasive diagnostic testing.
Methods:
A prospectively maintained database was reviewed comprising 6 consecutive months of arterial and venous procedures performed using an algorithm emphasizing CTA supplemented with other noninvasive imaging.
Results:
Eighty-five patients underwent 90 arterial or venous procedures, the majority of which were based on CTA. Preprocedure plans matched a successful intervention in 35 of 40 (88%) procedures performed in the interventional suite, and 48 of 49 (98%) procedures performed in the surgical suite. Two of 40 patients treated initially in the interventional suite eventually required a surgical vascular procedure. The majority of procedures were therapeutic (86%) rather than diagnostic (14%).
Conclusions:
An algorithm using CTA and supplemented with other noninvasive imaging allows safe and effective planning for open surgical and endovascular procedures.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
