Review Case Reports
False aneurysm of perforating branch of the profunda femoris artery after external fixation for a complicated femur fracture.
False aneurysm of the profunda femoris artery rarely occurs and is a serious complication following femur fracture. A 39-year-old man who developed a false aneurysm arising from the perforating branch of the profunda femoris artery following an external fixation for a complicated femur fracture was presented. Clinical diagnosis was confirmed by selective arterial angiography after occurrence of significant hemorrhage and swelling of the injured thigh. ⋯ The patient was discharged on the 10th postoperative day with external fixation. False aneurysm in a branch of the profunda femoris artery is a very rare status following application of the external fixator due to complicated femur fracture. Related literatures and interventions were reviewed on the basis of this case.

Severe pulmonary oxygenation impairment occurred in some patients with pleurotomy during the harvest of the internal mammary artery graft followed by coronary artery bypass grafting (CABG). Peripheral pulmonary atelectasis in the postoperative chest X-ray was detected in these patients. We studied the efficacy of intraoperative positive end-expiratory airway pressure (PEEP) therapy for the prevention of postoperative pulmonary oxygenation impairment. ⋯ In conclusion, PEEP therapy may prevent pulmonary atelectasis and oxygen impairment after CABG.
