Simple Evaluation of Left Hand Function after Thoracic Endovascular Aortic Repair with Obstruction of Left Subclavian Artery

We evaluated left hand function with or without obstruction of left subclavian artery for 29 cases of thoracic endovascular aortic repair (TEVAR). 18 cases of distal true aortic aneurysm were undergone surgery with simple direct closure of left subclavian artery (LSCA). The other 11 cases of true arch aneurysm were revascularized by axilla-carotid-axilla bypass grafting with TEVAR. Later 26 cases were evaluated by blood pressure, maximal grasping power, persisting duration of 60% maximal grasping power, circumferential length of upper and forearms, and simple test for evaluating hand function (STEF). Left hand blood pressure was significantly reduced than right side in obstruction group. But left hand function was not reduced in any other test. We concluded that no relationship between the obstruction of LSCA and the left hand function, and the influence of late survival and mobidity.
