A rare case of spontaneous aortic thrombosis presenting with unilateral auto-Lisfranc joint amputation in a young adult: A case report.

introduction and importanceSpontaneous aortic thrombosis is a rare clinical entity in young adults. Its rapid progression from intermittent claudication to critical limb ischemia presents significant diagnostic and therapeutic challenges. Early recognition and timely intervention are crucial to prevent severe complications. We report a rare case of spontaneous aortic thrombosis that presented with unilateral auto-Lisfranc joint amputation in a young adult. CASE PRESENTATION: A 22-year-old male presented with progressive intermittent claudication lasting five months, and a week's history of dark skin discoloration in both feet, leading to a left auto-Lisfranc joint amputation. Imaging studies revealed severe abdominal aortic thrombosis with absent blood flow to the lower extremities. Following this, an aorto-bifemoral bypass procedure was performed, resulting in an improved condition during discharge. CLINICAL DISCUSSION: This case underscores the atypical presentation of primary aortic thrombosis in a young adult with no identifiable risk factors. The striking occurrence of unilateral auto-Lisfranc joint amputation as the initial symptom is exceptionally rare. Imaging revealed extensive aortic thrombus without indications of vasculitis or an embolic source, thereby necessitating surgical revascularization.

conclusionEarly diagnosis and prompt intervention are crucial in preventing severe morbidity and limb loss related to acute limb ischemia. This case exemplifies the necessity for healthcare professionals to maintain heightened awareness of vascular diseases, particularly in young adults, and to act decisively to ensure optimal patient outcomes. Continuous follow-up, education on identifying symptoms of thromboembolism, and strict adherence to anticoagulation therapy are essential components in improving long-term prognosis and preventing recurrence.
