Purpose:
To report an acute endograft limb occlusion immediately subsequent to a total hip replacement.
Case Report:
A 62-year-old man underwent successful placement of a bifurcated stent-graft for a 5-cm abdominal aortic aneurysm (AAA). Surveillance imaging documented a satisfactory outcome and no defects in the stent-graft. Three months after the endograft procedure, he underwent left total hip arthroplasty, at which time the left endograft limb acutely thrombosed. He was successfully treated with thrombectomy and dilation/stenting of the thrombosed graft limb.
Conclusions:
Patients with aortoiliac stent-grafts need careful surveillance around the time of a procedure that may require extreme manipulation of the pelvis and hips. Even fully supported, widely patent endograft limbs may be vulnerable to acute thrombosis in this setting.
