This protocol presents a step-by-step instruction for harvesting the superficial inferior epigastric artery fascia (SIEF) flap and wrapping it around the reconstructed peroneal nerve defect in rabbits. This surgical addition of vascularization to the tissue bed of nerve grafts is used to improve regeneration outcomes.

Access for long-term infusion in the superior mesenteric artery (SMA) of rats is a surgical procedure that consists of cannulation of a proximal branch of the SMA. The cannula exits from the abdominal wound and is tunneled through the subcutaneous space back to the interscapular fold.

FAQs
After crossing the costal margin, the artery enters the rectus sheath and descends along the deep surface of the rectus abdominis. Muscular branches support the rectus muscle, while cutaneous branches supply nearby superficial tissues. This branching pattern connects the vessel’s proximal entry point with the structures of the upper anterior abdominal wall.
The connection near the umbilical region links arterial flow from the upper and lower portions of the anterior abdominal wall. This anastomosis creates a collateral pathway, meaning blood can reach local tissues through connected vessels rather than relying on only one direction of supply. Its presence is therefore important when evaluating abdominal wall perfusion.
The superior epigastric artery approaches the abdominal wall from above, whereas the inferior epigastric artery contributes flow from below. Their vessels meet near the umbilical region, so they represent complementary routes within the same vascular network. This arrangement helps explain why their relationship matters in anatomical assessment and procedures involving the anterior abdominal wall.
Its predictable course across the costal margin and along the deep surface of the rectus abdominis provides a reference for locating vessels within the abdominal wall. Surgeons can use this relationship when considering abdominal access or tissue movement. Recognizing the artery’s position helps support planning intended to preserve perfusion and reduce the possibility of vascular injury.
Flap design must account for the artery’s supply to the upper anterior abdominal wall, including its muscular and cutaneous branches. These branches indicate how tissue in that region receives blood and therefore provide relevant anatomical information when a flap is planned. Understanding the vascular territory supports designs that consider local perfusion rather than tissue location alone.
During laparoscopic access, the artery’s location within the rectus sheath and its descent along the deep surface of the rectus abdominis are relevant to selecting and evaluating entry sites. The vessel is a vascular landmark because an access path that disregards abdominal wall anatomy may increase the possibility of injury. Its course therefore informs prevention and assessment of bleeding.
