Fig. 2.

Complications after transradial percutaneous coronary procedures (TR-PCP) and the impact on upper extremity function. All complications affect upper extremity function after TR-PCP. The mechanism and the magnitude in which they affect function is partly known and partly unknown (black box). The circle below represents upper extremity function and the negative impact complications might have. a Very little is known about complications affecting upper extremity function after TR-PCP (red circle without overlap). However, there is awareness for the overlap part. Access-site complications (inner white circle) are described in the literature (Table 1). Major adverse cardiac and cerebral events (MACCE) (outer white circle) might influence upper extremity function as well, but were not investigated in this article. b Upper extremity function consists of several important physiological capacities as mentioned in the pie diagram. Pain is not a physiological parameter, but negatively affects all parameters of upper extremity function
