Abstract
The diaphragm is the most important respiratory muscles. Disturbances of movement diaphragm accompanied by various respiratory complaints such as difficulty inhaling and exhaling. It can simulate asthma. Disorders of the diaphragm kinetics may occur with the celiac artery compression syndrome (CACS, Dunbar syndrome).
The aim: of the study was to evaluate the functional activity of the diaphragm in patients with CACS and respiratory complaints simulate asthma.
Methods: The 44 patients with respiratory disorders and CACS (mean age 23.4 years) were studied. We evaluated: clinical manifestations, chest X-ray, spirometry, PImax and PEmax test, ultrasound duplex celiac artery (CA). Right hemidiaphragm function was investigated by ultrasound.
Results: Patients with CACS complaints were: shortness of breath (98%), exercise intolerance (87%), decreased working capacity (68%). In most cases, the standard treatment of asthma in patients with a diagnosis of asthma and CACS was ineffective. The phenomenon of bronchospasm were detected in 20% of patients. Extreme weakness of the respiratory muscles was detected in 20.5% of patients, moderately expressed - at 22.7%, light - at 20.5%. In patients correlations (p <0.05) were found: between fraction thickening diaphragm and proximal diameter CA (R = 0,33), and peak velocity (PV) of blood flow in the CA (R = -0,36); between the velocity diaphragm relaxation and PV in the CA (r = -0.34). In 90% of patients operated on for CPP after 6 months after surgery disappeared respiratory diseases.
Conclusion: Firstly - misdiagnosis of asthma can be supplied in patients with CACS. Secondly - the absence of effect from standard asthma therapy is an indication to exclude Dunbar syndrome.
