“Introduction A pseudoaneurysm of the peripheral artery is very rare and is generally a late sequela of trauma, iatrogenic injury, and general

illness. It is more infrequent in the upper limb vasculature than in the lower limb vasculature. Although there are many reported causes of brachial artery pseudoaneurysms, to our knowledge, this is the first report of delayed rupture of a brachial artery pseudoaneurysm during the rehabilitation of a patient with burns of the upper extremity who underwent fasciotomy and musculocutaneous flap coverage. We also present a review of the brachial artery pseudoaneurysm. Presentation of case A 26-year old male patient

presented ABT-888 mw to the hospital with wound dehiscence and oozing of the left axilla that had commenced two days earlier while undergoing rehabilitative therapy for postburn joint ankylosis and brachial plexus palsy of the upper extremity (Figure 1). According to the patient’s history, he had undergone escharectomy and latissimus dorsi musculocutaneous flap coverage of a neurovascular bundle exposed in the medial upper arm due to a contact burn of the left upper extremity six months earlier, in addition to a split-thickness skin graft for a lesion (Figure 2). At the time of the hospital visit, the patient’s blood pressure was 130/74 mmHg, and his heart rate was 98 bpm. The hemoglobin

value was 12.8 g/dl. The examination revealed no other specific findings. The wound was approximately 1 × 1 cm wide, with Galeterone bleeding in an oozing pattern. Distal pulsation and circulation had been maintained. Under the assumption that wound dehiscence had occurred during the rehabilitative treatment, a moderate compression gauze dressing was applied. The wound gradually healed, but wound rupture occurred again at the site of the posterior axilla on day 14 of hospitalization. The new site of wound dehiscence was due to a hematoma, which was accompanied by profuse bleeding. A gauze compression bandage was applied again, and a computed tomography angiography (CTA) was conducted. The CTA images revealed a pseudoaneurysm in the brachial artery (Figure 3). Due to the profuse bleeding from wound, the patient’s blood pressure was decreased to 90/50 mmHg, and the heart rate was increased up to 108 bpm. The hemoglobin value was also dropped to 8.2 g/dl. The patient underwent immediate surgical exploration and the pseudoaneurysm was approached through the marginal side of the previously performed latissimus dorsi musculocutaneous flap.
