Duplex ultrasound was performed which confirmed it to be a large pseudoaneurysm arising from right radial artery with a narrow neck (0.18 mm) (Figure 2).

Radial angiogram was performed through 6-F Judkins Right (JR) guide catheter (Medtronic Inc, USA) which revealed pseudoaneurysm, its narrow neck and large size (Figure 3A, B). 0.014-inch runthrough wire (Terumo Inc, Japan) was parked into distal branch of radial artery. 3.5x18-mm Graftmaster covered stent (Abott Vascular, USA) was positioned over the neck of pseudoaneurysm (Figure 3C).
The stent was slowly deployed at 14-atm
pressure (A); Subsequent angiogram demonstrated
complete exclusion of pseudoaneurysm without any
spillage of contrast into the sac (B).

The stent was slowly deployed over one minute time at 14-atm pressure (Figure 4A). Subsequent angiogram demonstrated complete exclusion of pseudoaneurysm without any spillage of contrast into the sac (Figure 4B).

Ultrasonography on the following day revealed partially thrombosed and completely excluded pseudoaneurysm and patent radial artery (Figure 5).
