Extraneous injection of the perivasal block results in damage to small vessels and hematoma formation. Usually, these hematomas are very small and can be managed without surgery by using rest, ice, and nonsteroidal anti-inflammatory drugs (NSAIDs).

Major surgical damage to spermatic vessels can result in testicular compromise and atrophy; this complication is often not realized until late in the postoperative course. This rare and unfortunate complication requires urologic consultation and may, ultimately, result in orchiectomy.

As with any surgical procedure, unrealized minor damage to the nerves can result in immediate postoperative pain or persistent chronic pain.
