Blue toe syndrome is when one or more of a person's toes starts to look blue or purple in color. It happens when blood vessels leading to the affected area become blocked.

Background Left atrial septal pouches (LASPs) are a relatively newly described but common anatomical cardiac variant thought to be associated with atrial fibrillation (AF) and cardio-embolic stroke. Blue toe syndrome (BTS) describes ischemic changes in the toes due to microembolisation of the digital arteries. Establishing the etiology of BTS is vital so that the underlying cause can be treated. Here we describe the first case of BTS arising due to emboli from LASP thrombus arising on a background of new-onset AF. Case presentation A 65-year-old man presented with a two-day history of progressive painful swelling and bluish-purple discoloration of the second and fourth toes of his left foot and new-onset AF. Tests for hypercoagulability disorders were negative. Duplex ultrasound and CT angiography excluded deep venous thrombosis and an absence of embolus, thrombus, or occlusion in the arterial tree in the lower extremities bilaterally, so BTS was diagnosed. While transthoracic echocardiography and chest CT initially showed no cardiac abnormalities or mural thrombus, subsequent transesophageal echocardiography revealed a LASP with an associated pedunculated thrombus. The affected toes were amputated due to wet gangrene, but the patient recovered well with thrombus resolution after anticoagulation. Conclusion The presence of a LASP in the absence of any other identifiable cause of BTS should trigger careful investigation of the interatrial septum, preferably using a multimodality imaging approach. The possibility that LASPs may not merely be an innocent bystander but a causative mechanism for peripheral ischemia must be considered.

The spontaneous onset of a painful unilateral blue toe is usually caused by fibrinoplatelet microemboli arising from an upstream stenotic or occlusive lesion of the iliac or femoral artery. This constellation of findings is referred to as the blue toe syndrome (BTS). In 12 patients who experienced 14 spontaneous episodes of BTS, angiography demonstrated 15 proximal atherosclerotic arterial lesions, which were presumed to be the source of the microemboli. Fourteen of the 15 lesions were short-segment stenoses or occlusions distal to the aortic bifurcation. Six lesions were treated with antiplatelet or anticoagulant drugs followed by delayed percutaneous transluminal angioplasty (PTA) 6-12 weeks later. Three lesions were treated with surgical bypass, three with long-term anticoagulation, and one with transcatheter clot aspiration and immediate PTA. Two were treated with immediate thrombolytic therapy and had embolic complications. Antiplatelet and anticoagulant therapy followed by delayed PTA may be an effective alternative to surgery for treating BTS.

The sudden development of cyanotic lesions on the feet may be a result of atheroembolic disease or a number of medical conditions. A careful history and physical examination, basic laboratory tests, and noninvasive vascular assessment usually distinguish between medical and surgical causes and...

• We describe 31 patients in whom proximal lesions in the arterial tree were identified as probable sources of emboli causing the "blue toe" syndrome. This syndrome consists of acute digital ischemia caused by microembolization to the digital arteries from a proximal source via a patent arterial...
