Acute septic deep venous thrombosis of the lower extremities due to foreign body injury and infection: a case report

Abstract Background: Septic deep venous thrombosis (DVT) of the lower extremities caused by foreign bodies is rare in the clinic, and the symptoms are serious. If the correct treatment is not implemented as soon as possible, the patient may progress to sepsis. Case presentation: We report the case of a 51-year-old normally healthy male who developed fever 3 days after field work. He was diagnosed with scrub typhus but did not respond well to anti-infective treatment. After a detailed inquiry of his medical history and an auxiliary examination, the diagnosis was confirmed as septic DVT of the left lower limb caused by a foreign body. After surgery, anticoagulation and anti-infection treatment, the infection and thrombosis were controlled, and the patient was cured and discharged. Conclusions: Early detection of the aetiology of sepsis and early adoption of the correct measures can effectively block the progression of the disease and reduce patients’ pain. Clinicians should identify the source of sepsis through a medical history and clinical examination.
