INTRODUCTION: In managing arterial rupture, stent-graft implantation may cause limb ischemia by crossing a major branch for hemostasis. The ViaHole technique could circumvent a major branch occlusion.
MATERIALS AND METHODS: The process involved advancing retrograde devices into an occluded major branch by the stent-graft implantation to reach the outer surface of the stent-graft, puncturing the stent-graft with a 20-gauge needle to touch the retrograde device, manipulating the guidewire through the needle hole and externalizing it, advancing the microcatheter into the proximal lumen, catching the microcatheter using an antegrade 4-Fr catheter, inserting an antegrade guidewire into the retrograde microcatheter to cross the stent-graft hole, dilating the lesion and stent-graft hole using a 3.0-mm balloon, and ensuring hemostasis at the puncture site.
RESULTS: A 72-year-old male with a history of stent-grafted treatment for right popliteal aneurysm presented with acute limb ischemia (ALI). The occlusion spanned distal superficial femoral artery to the below-the-knee arteries. Hemostasis was achieved after an unintentional rupture of the proximal posterior tibial artery during surgical thrombectomy by implanting endoluminal stent-grafts instead of surgical bypass due to no distal anastomosis site. However, recurrent ALI occurred three months later. Surgical bypass was again deemed unfeasible due to no run-off. Unsuccessful recanalization attempts of the bilateral tibial arteries led us to perform the ViaHole technique to recanalize the peroneal artery occlusion. Finally. successful revascularization was achieved, and 1-year patency was confirmed.
CONCLUSIONS: The ViaHole technique may be valuable for revascularizing a major side branch occluded by stent-graft implantation.
