Endovascular treatment for post-traumatic pseudoaneurysm (PsA) has been deemed effective and minimally invasive. However, embolization of all feeding and outflow vessels is difficult if multiple fine arteriovenous fistulas (AVFs) are present. In the present case, PsA of the medial plantar artery with AVF was diagnosed 1 month after injury by a rusty nail. Treatment using a combination of embolization of only the main feeding artery and percutaneous thrombin injection into PsA was successful. This approach can completely resolve PsA in narrow vessels, such as in the foot, particularly when AVF is present with numerous connected vessels.

The VIABAHN stent graft is often used for traumatic and iatrogenic vascular injuries. In this case, vascular injury at both edges of the VIABAHN stent graft was noted 4 months after endovascular repair for idiopathic superficial femoral artery (SFA) rupture. The longitudinal compression of the SFA with a decrease in hematoma size was assumed to exceed the flexibility of the stent graft. Thus, the use of stent grafts for vascular injuries with giant pseudoaneurysms may result in late vascular injuries at both edges of the stent graft. Therefore, cautious assessment of its indications and strict surveillance are required.
