Аннотация
BACKGROUND: Buerger disease, also known as Winiwarter-Buerger disease or thromboangiitis obliterans (TAO), is a non-specific inflammation of small- and medium-sized arteries with thrombus obliteration and without atherosclerotic changes. Patients with TAO can develop chronic limb-threatening ischaemia (CLTI) and are at risk of limb amputation despite smoking cessation and exercise therapy recommendations.
CASE SUMMARY: A 72-year-old Japanese man presented with painful discolouration of toes and renal impairment. He was diagnosed with Rutherford classification Stage 6 CLTI with immunoglobulin A nephropathy. He refused limb amputation. Clinical symptoms reduced after treatment with low-intensity pulsed ultrasound (LIPUS). LIPUS is a non-invasive option to alleviate peripheral arterial disease symptoms. Despite the initiation of conventional therapy measures, there was a worsening of the limb condition. The non-invasive investigational treatment option of LIPUS was initiated after the poor clinical outcomes of the conventional therapy measures. The patient's symptoms in the bilateral lower limbs, ulcers, and the blue-coloured toes gradually lessened. After 1 year of treatment with LIPUS, he had achieved better walking independence with improved quality of life.
DISCUSSION: Low-intensity pulsed ultrasound is a non-invasive option for therapeutic angiogenesis with the potential to improve ischaemic limb conditions in patients with peripheral arterial disease and to avoid major amputation procedures.
