Estudo de caso: Aplicação da terapia a laser de classe 4 na cicatrização pós-operatória de feridas na sequência de uma amputação da cauda (caudectomia) num cão

Introdução

Tail injuries in pets are primarily caused by traumatic forces such as pinches and impacts, strenuous exercise strain, skin diseases, frostbite, underlying orthopedic/neurological disorders, and self-mutilation due to psychological stress, extreme pruritus (itching), or self-defense instincts. Following a caudectomy (tail amputation surgery), post-operative wounds commonly exhibit symptoms such as redness, swelling, exudation, abnormal scabbing, and elevated skin temperature. In severe cases, this can lead to wound ulceration, suppuration, and abnormal granulation tissue hyperplasia. Without timely care and intervention, delayed wound healing, recurrent inflammation, and excessive scarring may occur, or even progress to tissue necrosis and systemic infection, severely impacting post-op recovery and appearance.

Terapia laser de classe 4 is currently an advanced, non-invasive physical modality in veterinary clinical medicine applied to surgical wound repair and post-operative inflammation resolution. It offers significant advantages in being safe and non-invasive, providing anti-inflammatory and bactericidal effects, reducing edema and pain, accelerating granulation tissue growth, and promoting epidermal repair. It effectively overcomes the limitations of traditional care methods, enhancing surgical wound healing efficiency and quality. This report documents the complete recovery process of a Shiba Inu using VETMEDIX (FotonMedix) laser equipment, providing a scientific reference for similar complications.

05 Resumo do caso

Recuperação a curto prazo: The veterinary clinical team at Hangzhou Songzi Pet Hospital implemented a targeted Terapia laser de classe 4 protocol for the Shiba Inu patient suffering from poor post-operative wound healing and localized inflammation. During the treatment cycle, daily laser-assisted therapy sessions were conducted. Redness, swelling, and elevated skin temperature at the surgical site subsided progressively, while exudation and minor bleeding improved significantly. The scope of inflammatory infiltration narrowed, wound pain was markedly reduced, the amputation surface dried and contracted, and new granulation tissue grew in an organized manner, leading to a steady recovery of the pet’s appetite and spirit.

Acompanhamento a longo prazo: Following discharge, the patient received appropriate wound protection and restricted strenuous exercise to avoid stretching the incision, along with regular follow-up check-ups to track tail stump healing and tissue recovery. Long-term follow-up results indicated that the amputation wound had completely healed. The scabs shed naturally, leaving the skin flat and smooth. No common post-operative complications—such as ulceration, suppuration, abnormal granulation tissue hyperplasia, scar adhesion, or recurrent infection—were observed. The dog’s tail mobility has returned to normal, allowing it to run and play freely in a healthy state.

Conclusão: This case demonstrates the significant clinical value of VETMEDIX small animal high-power laser rehabilitation in canine wound healing. Utilizing Photobiomodulation (PBM) technology, terapia laser para tecidos profundos acts non-invasively on the tail amputation site to effectively optimize local blood circulation, dissipate post-operative inflammatory edema, alleviate wound pain, and inhibit the proliferation of pathogens. By accelerating granulation tissue growth and epidermal repair, it drastically shortens the wound healing cycle, showcasing prominent clinical advantages in terapia laser em medicina veterinária.
