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.

Surgical correction of ALCAPA is highly recommended, regardless of age or the degree of intercoronary collateralization. This protocol presents a technique for the direct re-implantation of adult-type ALCAPA into the aorta to re-establish the dual-coronary perfusion. Whenever feasible, direct re-implantation is preferred to other surgical correction techniques.

Coronoid-Temporalis Pedicled Flap for Orbital Floor Defect Reconstruction
0 Views •
2025
This protocol presents a novel coronoid-temporalis pedicled flap (CTPF) technique for reconstructing small-to-medium orbital floor defects. CTPF avoids microvascular risks while maintaining biomechanical stability. Clinical cases demonstrate effective structural restoration, reduced complications, and preserved facial symmetry, offering a viable alternative to traditional grafts or alloplastic materials.
FAQs
The repair must maintain continuity in the main vessel while also keeping the branch opening unobstructed. This allows blood to pass through the reconstructed segment and continue into separate downstream territories. Careful alignment at the branching point is therefore essential, because an otherwise successful repair could still compromise circulation to tissues supplied by the branch.
A branching point has to accommodate blood flow through connected vessel pathways rather than a single straight segment. Misaligned sutures, an unsuitable graft connection, or narrowing at the junction can interfere with passage into one or both vessels. Preserving the channel and matching the vessel anatomy helps support downstream perfusion after reconstruction.
The strategy depends on the location and condition of the damaged or narrowed segment, the anatomy of the branch, and the need to preserve circulation to multiple tissue regions. Surgeons may remove the affected segment and reconnect the vessels or bypass it with a graft. Precise anatomical and perfusion assessment guides this individualized choice.
Removing the affected segment permits direct reconnection of the remaining vessel ends when their condition and position allow it. Bypassing instead routes blood around the damaged or narrowed area with a graft while preserving access to the relevant branch. Both approaches seek to restore continuity, but the selected option reflects the vessel anatomy and lesion characteristics.
Planning begins with detailed assessment of vessel anatomy and the circulation supplied by the main artery and branch. The surgeon then removes or bypasses the abnormal segment, reconnects the vessels with carefully aligned sutures or a graft, and considers whether the reconstructed pathway remains open for blood passage. These steps focus on preserving downstream perfusion.
This approach may be considered for arterial injury, aneurysmal disease, or complex occlusive conditions when a branching vessel must remain functional. Its value extends beyond repairing the visible lesion: maintaining blood flow can help protect downstream organs and tissues. The procedure also provides a clinical framework for developing more individualized strategies in vascular surgery.
