The electrophysiological recording of the carpal tunnel syndrome exaggerated in the hypertensive patients

Abstract

Objective The disturbance of blood flow (BF) in the intrinsic microvasculature of the median nerve is closely involved in the entrapment of the median nerve. The chronic hypertension (CHt) causes interference with the endoneurial microcirculation and may lead to endoneurial edema and ischemic changes in the nerves.
Methods Thirty two patients, 6 males and 26 females, aged (41.5 ± 10.2) were elected to study the change in the severity of bilateral carpal tunnel syndrome (CTS) before and after suffering of CHt. All patients included in this study were subjected to the electroneurography (ENG).
Results The effect of CHt on median nerve compression causes worse severity, where the effect of CHt is indicated by the severity of the CTS and the recording of nerve conduction studies. All the elected patients diagnosed with CHt in these studies are becoming more severe of CTS after 4 months. The severity of the syndrome from mild or moderate become severe in some cases after the recording of CHt. Very high significant difference (P < 0.05) of the sensory and motor nerve conduction study’s parameters as distal sensory and motor latency, sensory and motor conduction velocity and amplitude between the two recordings, before and after diagnosis of CHt.
Conclusion The severity of entrapment of median N (CTS) affected worse after the patients suffering from the chronic hypertensive.
