2. Fig. 1
Schematic diagram shows C-arm in position with patient on radiolucent table. Arrow indicates potential rotation of C-arm to obtain varying obliquities of projection. C-arm requires power source and is connected in the operating room to mobile DSA unit (IDIS).

4. Fig. 3
Left, Completion operative DSA illustrates stenosis at distal end of arteriotomy as a result of a suture (arrow). Right, Operative completion DSA in same patient after revision by patch angioplasty. Also illustrated (lower arrow) is the “shelf” at the proximal end of the endarterectomy from the diffusely thickened atherosclerotic wall of the common carotid artery.

5. Fig. 4
Left, Operative DSA illustrates stenosis at distal end of endarterectomy as a result of platelet thrombus (arrow). Right, Repeat operative DSA in same patient after removal of platelet thrombus and revision with patch angioplasty.

6. Fig. 5
Operative DSA illustrates what were thought to be insignificant irregularities along internal carotid suture line (arrow, both sides of internal carotid). Intravenous DSA 3 weeks after operation shows occlusion of internal carotid artery at its origin.
