Injury of the common peroneal nerve after cardiothoracic operations.
BACKGROUND
To assess incidence, etiology, and clinical relevance of common peroneal nerve injury (CPNI) in patients after cardiothoracic surgery.


METHODS
In an 11-year period, CPNI was detected in 39 out of 20,718 patients (0.19%): 38 times after cardiopulmonary bypass (CPB) (38 of 12,726; 0.30%) and in 1 patient after a non-CPB procedure (1 of 7,992; 0.013%). These patients underwent intensive physiotherapeutic treatment. As the majority of CPNI occurred after CPB (97.4%), data of these patients were compared with a 1-year set of 1,032 patients who underwent CPB procedures.


RESULTS
Patients with CPNI were older, had a higher percentage of subnormal body weight, and had considerable comorbidity such as peripheral arteriosclerotic disease, diabetes mellitus, and arrhythmias. Follow-up was complete (mean: 5.2 years; 0.4 to 10.7 years). Twenty-eight patients were free of symptoms; 10 patients complained of moderate symptoms, but were not limited in their everyday life; 1 patient still suffers from severe sensorimotor symptoms.


CONCLUSIONS
CPNI after cardiothoracic surgery is rare. Duration of the operative procedure, an increased comorbidity, and a subnormal body weight are assumed to have an etiologic impact. Prognosis is mostly good, but early physiotherapeutic treatment is crucial for prognosis.
