Massive hemorrhage from arterial access in patients receiving anticoagulation and
antiplatelet therapy is a rare but potentially devastating complication. The authors
present a patient who developed a large retroperitoneal and anterior abdominal wall
hemorrhage following an unintentional and unrecognized arterial injury during an endovascular
procedure. Reversal of anticoagulation in patients who have undergone stent-assisted
coil embolization of intracranial aneurysms is an undesirable approach due to the
risk of thromboembolism; rather, transcatheter embolization of the bleeding source
should be considered.
