(a) Volume-rendered image showing aneurysmal dilatation of the LIMA (white arrow) fistulized with the left brachiocephalic vein (black arrow). (b) Three-dimensional reconstructed images show aneurysmal dilatation of the LIMA (small black arrow) near its origin from the subclavian artery (large black arrow) and its relationship with the left subclavian and brachiocephalic vein (white arrow). (c) Selective arteriogram of the subclavian artery demonstrating aneurysmal dilation of proximal LIMA (white arrow) and fistulization with the left brachiocephalic vein (black arrow). (d)  Successful coil embolization of LIMA (arrow) showing closure of AVF.

IMA fistulized with the brachiocephalic vein (Figures 1(a) and 1(b)). Invasive angiography confirmed the presence of a fistula between the IMA and brachiocephalic vein. She underwent successful coil embolization of the IMA and aneurysm (Figures 1(c) and 1(d)).

Case 2 arteriograms of the LIMA fistula with the proximal subclavian vein. Initial angiogram (a), during coil deployment (b), and final angiogram (c) showing successful closure of the AVF. (white arrows, subclavian/brachiocephalic venous system; black arrows, subclavian artery and IMA).

Angiography was performed showing a large pseudoaneurysm as well as an AV fistula joining the LIMA to the proximal subclavian vein (Figure 2(a)). Subsequently, a total of 4 coils were deployed in the proximal portion of the LIMA (Figure 2(b)). A week after intervention, a repeat LIMA angiogram demonstrated closure of the AV fistula (Figure 2(c)).
