Rare case of Postpartum Hamman's syndrome presenting with facial asymmetry- A report
Dr Julian Wijesuriya at Department of Anaesthetics and Intensive Care Medicine, Lister Hospital, Stevenage, UK and colleagues have reported a rare case of Postpartum Hamman's syndrome presenting with facial asymmetry.The case has appeared in the BMJ Case Reports.
Hamman's syndrome describes the rare complication of straining affecting 1:100 000 live births in which barotrauma results in lung injury, pneumomediastinum, and surgical emphysema.
A 24-year-old primi parturient with suspected acute stroke was transferred urgently to the consultant-led obstetric unit following normal vaginal delivery of a healthy baby under midwifery-led care. The patient had no significant medical history and, other than having a low body mass index at booking (17 kg/m2) and delivering a large baby (>90th centile), she had undergone a normal pregnancy and delivery.
Immediately following delivery, the patient developed facial asymmetry with left-sided swelling and drooping and altered voice. Urgent clinical assessment revealed cardiorespiratory stability and, other than mild dysphonia, no evidence of acute stroke; there was marked surgical emphysema extending from the chest up to the face.
A portable chest radiograph demonstrated surgical emphysema but no evidence of pneumothorax. The ruptured esophagus was suspected and a CT of the neck and chest with contrast was requested. This demonstrated pneumomediastinum, a small apical pneumothorax and no evidence of oesophageal rupture (figure 1).
The diagnosis of Hamman's syndrome was made and, following a period of observation and conservative management, the patient was discharged home with outpatient respiratory follow-up.
Treatment is usually conservative, however, it is important to fully investigate such patients to exclude other diagnoses such as Boerhaave's syndrome, which may require surgical intervention. Extensive surgical emphysema may distort head and neck anatomy, with resultant facial and vocal changes suggesting neurological pathology (figure 2). However, a thorough clinical examination should narrow the differentials and radiological investigation will confirm the diagnosis.
Learning points
Hamman's syndrome is a rare complication of normal labour.
The diagnosis must be urgently differentiated from the more serious Boerhaave's syndrome.
Extensive surgical emphysema may cause facial asymmetry and dysphonia, mimicking stroke.
