Complications of Genitofemoral Nerve Block<br />
Because of <strong>the</strong> presence of multiple vessels in <strong>the</strong> spermatic<br />
cord (pampini<strong>for</strong>m plexus and testicular arteries), <strong>the</strong> blind<br />
technique is associated with <strong>the</strong> possibility of an intravascular<br />
local anes<strong>the</strong>tic injection and subsequent systemic intoxication.<br />
The per<strong>for</strong>ation and damage of <strong>the</strong> testicular artery with <strong>the</strong><br />
potential of subsequent bleeding and hematoma <strong>for</strong>mation is<br />
also a well-described serious side-effect of <strong>the</strong> blind technique<br />
(Goldstein 1983).<br />
The injection should be per<strong>for</strong>med with an ultrasound<br />
technique and administered just below <strong>the</strong> “click” of <strong>the</strong><br />
external oblique aponeurosis and after aspiration.
