Sciatic nerve loop engulfing perforator arteries - a case report

The sciatic nerve is the thickest in the human body; however, it is susceptible to a wide range of anatomical variations with potential clinical implications. Some variations are very rare and unreported in the existing literature We present a case of a middle-aged male cadaver with a sciatic nerve giving a loop where 3 perforator arteries from the profunda femoris artery pass; the loop bundles were reforming the main nerve distally. A sciatic nerve loop engulfing muscular perforator arteries is a scarce anatomical variation worth knowing for clinical, academic, and research interests.
