The latissimus dorsi flap is a highly versatile reconstructive option used in head, neck, torso, and breast reconstruction surgeries. Surgeons harvest the flap from the latissimus dorsi muscle, which is richly vascularized by the thoracodorsal vessels. This ensures flap viability and enables its use as a pedicled or free tissue transfer method. This versatility provides ample soft tissue coverage for large defects with excellent skin color and texture match, making it particularly advantageous for aesthetic reconstruction. Early recognition and intervention can often salvage the flap despite potential complications such as flap failure or vascular compromise. Overall, the latissimus dorsi flap is a valuable tool in the armamentarium of reconstructive surgeons, offering effective solutions for complex defects. Recent advancements have also extended the use of the latissimus dorsi flap to neophallus construction for transgender individuals, showcasing its evolving versatility. This activity provides clinicians with a comprehensive understanding of using the latissimus dorsi flap in reconstructive surgery, emphasizing flap harvest, transfer techniques, perioperative management, patient selection, and postoperative care strategies. This activity enables interdisciplinary healthcare professionals to refine their skills in managing diverse clinical scenarios, emphasizing the indispensable role of the latissimus dorsi flap in modern surgical practice. By fostering interdisciplinary collaboration and communication, this activity equips healthcare professionals to effectively incorporate the latissimus dorsi flap into their practice, leading to enhanced patient-centered care and improved surgical outcomes.

The latissimus dorsi flap, whether myocutaneous or myofascial, is a highly versatile reconstructive option used in head, neck, torso, and breast reconstruction surgeries, providing a versatile solution to a wide range of reconstructive challenges (see Image 3. Latissimus Dorsi Myocutaneous Free Flap and Image 4. Latissimus Dorsi Myofascial Free Flap).[1][2][3] Surgeons harvest the flap from the latissimus dorsi muscle, which is richly vascularized by the thoracodorsal vessels. This ensures flap viability and enables its use as both a pedicled and free tissue transfer method. This flap provides an abundant source of pliable soft tissue, a quality often lacking in alternative flap options. Moreover, the myocutaneous version of the latissimus dorsi flap is designed to include skin and subcutaneous tissue, providing extra bulk as needed, thereby enhancing its versatility across various clinical scenarios.[4] With minimal absolute contraindications and remarkable versatility, this flap presents itself as an indispensable tool in the arsenal of reconstructive surgeons, offering effective solutions for complex defects. In postmastectomy breast reconstruction, the pedicled latissimus dorsi transfer is commonly used, and its application also extends to free functional muscle transfer for facial reanimation.[5][6][7] Whether utilized as muscle alone or including skin, the pedicled latissimus dorsi flap can effectively address chest or neck defects without tension. This approach is particularly advantageous for women with neck defects, avoiding potential breast deformities linked with pectoralis flap reconstruction. In extensive cases, surgeons may harvest a mega flap that includes the latissimus dorsi and parascapular soft tissue, along with the subscapular artery, circumflex scapular, and thoracodorsal branches. These mega flaps may necessitate the inclusion of scapular bone, rib, and the serratus anterior muscle for reconstruction purposes.[8]

Consequently, the latissimus dorsi flap continues to evolve, broadening its range of applications and confirming its crucial role in modern surgical practice.

The most concerning complication in flap surgery is flap failure, which can manifest as partial or complete loss due to vascular compromise during the initial few weeks of healing.[8] Prompt recognition and intervention are crucial for salvaging compromised flaps. Timely recognition of vascular compromise is essential, as early intervention can salvage flaps by addressing vascular occlusion and kinking or using leech therapy to mitigate venous congestion. Leeches aid in flap salvage by directly removing venous blood and secreting hirudin, which is a natural anticoagulant that inhibits thrombin from converting fibrinogen to fibrin and activating platelets.[18] However, when using leeches, the prophylactic administration of a fluoroquinolone antibiotic is crucial to prevent potential infection from Aeromonas hydrophila, commonly found in the gut of medicinal leeches.[19] Despite interventions, prolonged venous congestion or inadequate arterial inflow may lead to irreversible flap loss. Early recognition of vascular insufficiency in a free latissimus dorsi flap is paramount, as irreversible microcirculatory damage can occur after 6 hours of ischemia.[20] A swift return to the operating room is crucial for restoring perfusion, with up to a 90% salvage rate achievable if corrective measures are promptly implemented.[21] Most vascular occlusions occur within the initial 48 hours, with later thromboses posing a lower salvage likelihood, particularly for muscle flaps.[21] To optimize circulation while preparing for urgent reoperation, interventions may include releasing sutures overlying the pedicle and administering aspirin and heparin. Another option is injecting a high-dose thrombolytic, such as streptokinase or urokinase, into the flap itself and draining it out of the flap vein rather than into the systemic circulation if direct mechanical thrombectomy fails.[22]

Effective patient-centered care and optimal outcomes in latissimus dorsi flap procedures require a collaborative approach among interprofessional healthcare providers, including physicians, advanced practitioners, nurses, and pharmacists. Surgeons must demonstrate proficiency in flap harvest and transfer techniques, as well as ensure meticulous dissection and hemostasis to prevent complications such as hematoma formation. Interprofessional communication is crucial throughout the perioperative period, with anesthesiologists and surgical teams working together to maintain hemodynamic stability and optimal flap perfusion. Nurses are critical in preoperative patient education, postoperative monitoring, wound care, and pain management. Pharmacists ensure appropriate antibiotic prophylaxis and pain management regimens. Advanced practitioners facilitate comprehensive preoperative assessments and optimize patient health status before surgery. Through interdisciplinary collaboration and clear communication, healthcare teams can enhance patient safety, satisfaction, and outcomes in latissimus dorsi flap procedures.
