Alternative venous outflow vessels in microvascular breast reconstruction

Area of Science:

• Plastic Surgery
• Microsurgery
• Reconstructive Surgery

Background:

• Microvascular breast reconstruction is often complicated by inadequate recipient vessels post-mastectomy and irradiation.
• Size mismatch in outflow veins contributes significantly to thrombosis and flap failure.

Purpose of the Study:

• To review the authors' experience using alternative venous outflow vessels in microvascular breast reconstruction.
• To evaluate the efficacy and safety of external jugular and cephalic veins as outflow conduits.

Main Methods:

• Retrospective analysis of 1278 microvascular breast reconstructions over 10 years.
• Identification of patients utilizing external jugular or cephalic veins for venous outflow.
• Analysis of patient demographics, flap types, reasons for alternative vessel use, and complication rates.

Main Results:

• External jugular vein used in 23 flaps (22 patients), primarily with superior gluteal and TRAM flaps.
• Cephalic vein used in 11 flaps (11 patients), predominantly with TRAM and superior gluteal flaps.
• Alternative vessels frequently used due to size mismatch (74% for external jugular vein).
• Flap salvage rates were high when using these veins, with low complication incidence (one minor neck hematoma).

Conclusions:

• External jugular and cephalic veins are valuable ancillary options for microvascular breast reconstruction.
• These vessels are straightforward to dissect, well-tolerated, and associated with high success rates.
• Their use can mitigate complications arising from inadequate primary recipient vessels or size mismatches.
