Complications of the procedure include infection, allergic reactions to the materials used, intravasation of the material, and, if oil-based material is used, embolisation.

Later, C.R. Leedham-Green showed that such an R may constructed as the integral closure of a PID in a quadratic field extension (Leedham-Green 1972).
A demultiplexer extracts elementary streams from the transport stream in part by looking for packets identified by the same PID.
