Highlights

  • Thrombotic complications have been increasingly observed in patients with COVID-19.

  • Confirming IGG and IGM + by immunochromatographic method.

  • AngioCT showing signs of arterial embolization to both limbs.

  • The patient underwent in the right lower limb thromboembolectomy.

  • Tricompartmental fasciotomy was performed to prevent compartment syndrome.

Abstract

Introdution

COVID-19 infection may predispose to venous and arterial thromboembolism due to excessive inflammation, hypoxia, immobilization and disseminated intravascular coagulation; however, there are few reports of lower limb ischemia as the main manifestation of the disease.

Presentation of case

Male patient, 69 years old, asthmatic, ex-smoker and bearer of systemic arterial hypertension, has been admitted to the emergency department with sudden onset of pain in the right lower limb (RLL), associated with cyanosis and reduced temperature of the limb. He has been tested for COVID-19 in the OR with positive result for IGG and IGM. Computed tomography angiography (AngioCT) was performed, showing signs of arterial embolization to both limbs, right internal iliac artery, and superior mesenteric artery. Faced with the threat of limb loss and the absence of signs and symptoms of visceral ischemia, the patient underwent full anticoagulation and RLL thromboembolectomy and tricompartmental fasciotomy. He was discharged after 7 days of hospitalization and demonstrated no other signs and symptoms of COVID-19, following outpatient follow-up.

Discussion

COVID-19 is associated with high risk of thrombotic complications being related to the clinical severity of the patient, with few studies that show symptoms of sudden pain in the lower limb without other complaints.

Conclusion

Individuals infected with COVID-19 are at risk for arterial thromboembolic events, and knowledge of such cases is essential in order to create specific protocols for prophylaxis of thrombotic events in these patients, in addition to increasing the suspicion of infection in individuals with acute arterial occlusion, mostly during pandemic times.
