[Surgical Therapy of Acquired Unilateral Diaphragmatic Paralysis: Indication and Results].
Unilateral elevation of the diaphragm may be due to various causes and requires further elucidation when the aetiology is unknown. Elevation of the diaphragm is often caused by diaphragmatic paralysis, either due to damage to the phrenic nerve or to the phrenic muscle. Patients typically complain of increased respiratory distress when lying down, bending or swimming. Basic diagnostic testing consists of a chest X-ray, as well as spirometry and computer tomography of the neck and chest. In many cases, no cause can be identified for the diaphragmatic paralysis. In symptomatic patients, diaphragm plication leads to fixation and thus to a reduction in the paradoxal respiratory movement of the paralysed diaphragm. In a large majority of studies, this results in significant and lasting improvement in vital capacity and respiratory distress. Spontaneous recovery of diaphragm paralysis is possible, even after several months, so a waiting period of at least 6 months should elapse before diaphragmatic plication is performed, if the clinical situation allows. The procedure can be performed minimally invasively, with low morbidity and mortality. When cutting the phrenic nerve, a nerve suture is recommended, if possible, or otherwise diaphragm plication during the procedure, especially in the case of pneumonectomy. This review provides an overview of the causes, pathophysiology, symptoms, diagnosis, therapy and results of diaphragmatic plication in acquired, unilateral diaphragmatic paralysis in adults, and suggests an algorithm for diagnostic testing and therapy.
