Pseudoaneurysms are created by a traumatic or iatrogenic perforation of an artery, resulting in accumulation of blood between the two outermost layers of a blood vessel, the tunica media and tunica adventitia. Pedal artery pseudoaneurysms are an extremely uncommon complication of foot and ankle surgery; therefore, few cases have been reported in the literature. Early diagnosis is important to ensure timely treatment of this condition. Once clinical suspicion has been established, urgent referral to the vascular surgery clinic for prompt surgical evaluation is required to prevent potentially harmful sequelae. We present the case of a 70-year-old woman who developed a pseudoaneurysm of the dorsalis pedis artery 33 days after undergoing open reduction and internal fixation of a second metatarsal fracture. Her treatment included urgent referral to the vascular surgery clinic with subsequent surgical repair of the pseudoaneurysm by means of ligation of the medial dorsal branch of the dorsalis pedis artery. At 10-month follow-up, she denied any pain, sensory deficits, or functional disability and had returned to all preinjury activities, with no recurrence of the pseudoaneurysm. Our case study demonstrates early diagnosis and successful treatment of a pseudoaneurysm of the dorsalis pedis artery that developed shorty after open reduction and internal fixation of a second metatarsal fracture.
Staphylococcus pseudintermedius is an emerging zoonotic pathogen that is very similar to human Staphylococcus pathogens, particularly multidrug-resistant Staphylococcus aureus. Recent reports have indicated that S pseudintermedius is easily transmitted between pets (mainly dogs) and owners because of these similarities. Although this pathogen has been associated with diabetic foot infections, it has not yet been described in the podiatric medical literature. In this case report, we present a diabetic foot infection in a 61-year-old man that was refractory to multiple rounds of antibiotic drug therapy. Deep wound cultures eventually grew S pseudintermedius, which was the first known case of this pathogen reported in our hospital system.
