Breast Reconstruction Flap Salvage

Краткая информация для пациента

Есть ли FDA-допуск для этого показания?

Yes — FDA-cleared under K040187 (June 21, 2004) for medicinal leech application to relieve venous congestion in microsurgical reconstructive procedures, including breast reconstruction flaps.

Какие доказательства существуют?

This is an FDA-cleared use. The largest published hospital series (Nguyen 2012, n=154) reports that about 78 percent of congested DIEP flaps were saved when leech therapy was added to surgical re-exploration. Major U.S. cancer centers (MD Anderson, Memorial Sloan Kettering, Mayo) include leech availability in their post-operative protocols. Leeches do not replace surgery — if the issue is an artery problem or a fixable surgical clot, the surgical team must address that first.

Основные риски

• Bleeding from each bite site for 6 to 10 hours after the leech detaches
• Need for blood transfusion (about 1 in 3 patients) from cumulative blood loss over the treatment course
• Aeromonas hydrophila infection (your team starts an antibiotic such as ciprofloxacin before the first leech)
• Loss of the flap despite treatment if the underlying artery problem cannot be fixed
• Allergic reaction to leech saliva (uncommon)
• Visible bite-mark scarring on the reconstructed breast that may fade but may not disappear entirely
• Longer hospital stay and emotional stress from a complication after an already long surgery

Кому не следует это рассматривать

• Patients on warfarin, apixaban, rivaroxaban, dabigatran, or heparin
• Patients with hemophilia or another inherited bleeding disorder
• Patients with severe anemia (hemoglobin under 10 g/dL) before therapy
• Patients with active bloodstream infection or sepsis
• Patients allergic to ciprofloxacin and other antibiotics covering Aeromonas
• Patients whose flap has completely died (no salvage is possible — surgical removal is needed)
• Patients whose flap problem is an artery issue (this requires surgical revision, not leeches)

О чём спросить врача

• Is this an artery problem, a vein problem, or both? Leeches only help with vein problems.
• Should I be taken back to the operating room before or instead of starting leech therapy?
• Which antibiotic will I get for Aeromonas prevention, and for how long?
• How often will my blood count be checked, and at what level would you transfuse?
• How will the bite scars look once everything heals, and is there anything that helps them fade?
• If the flap fails despite leeches, what are my options — a new flap from a different site, an implant, or no reconstruction?
• Will my breast cancer follow-up care be affected by this complication or by the transfusions?

Когда срочно обратиться за медицинской помощью

• Bleeding from any bite site soaking through more than one dressing per hour, or bleeding lasting more than 24 hours after the leech detaches
• Increasing redness, warmth, swelling, or pus around the flap or bite sites
• Fever above 38.0 C / 100.4 F, chills, or feeling suddenly unwell
• Flap turning darker, colder, or harder despite leech therapy
• Hives, swelling of the face or tongue, or any breathing difficulty
