I do recall Kiba was in that exact situation (or was it his right hand?) when he fought against Siegfried for the final time and they got his arm back on.

The only difference I can think of is that it may have a heavy effect on Issei's body similar to extreme shock, especially if this happened while in his Balance Breaker state.
