*3.3.2 Neurovascular structures*

The vascular structures that need attention in hip surgery in general and in hip arthroscopy in particular are essentially the common femoral artery (CFA) and its two terminal branches, the profunda femoris artery (PFA) and the superficial femoral artery, (SFA) as well as three lateral branches, which are the circumflex superficial iliac artery (CSIA), the lateral circumflex femoral artery (LCFA), and the medial circumflex femoral artery (MCFA) (**Figure 6**).
