Introduction: The management of extracranial arterio-venous malformations (AVMs) is complex and often requires a multidisciplinary approach. Currently, treatment includes surgical resection and embolotherapy. Methods: We present the case of a foot AVM that was managed with adjuvant radiotherapy after previous surgery and embolotherapy had been attempted, and we discuss the role of radiotherapy in the management of extracranial AVMs. Results: The malformation was successfully eradicated with complete obliteration of the nidus and no recurrence. Conclusions: The addition of radiotherapy in the management of extracranial arterio-venous malformations offers promising results using similar doses to those used in brain AVMs.

Aunque existe abundante literatura sobre las distintas complicaciones de los colgajos libres, la descripción de necrosis superficial completa en colgajos libres es escasa. Presentamos un caso de reconstrucción postraumática de pie con colgajo libre de músculo gracilis, que en el postoperatorio desarrolló una escara oscura y seca que cubría toda su superficie y semejaba una pérdida total del colgajo. Sin embargo, el pedículo del colgajo mantuvo en todo momento un tono activo en ecografía doppler, por lo que se decidió un manejo expectante. De manera diferida, se realizó cirugía de revisión con desbridamiento de la escara y del tejido necrótico superficial a los 21 días, descubriendo tejido sano del colgajo subyacente, que fue injertado. Posteriormente, el colgajo mostró una evolución favorable con una buena integración del injerto. Aunque en nuestro paciente no se identificó la causa exacta de esta complicación, se discuten las posibles etiologías con especial hincapié en el tabaco como factor de riesgo.

Background: In facial palsy reconstruction, static techniques with the use of slings can improve the appearance and functionality of the paralyzed face and may be used in patients who cannot undergo complex surgeries or as an ancillary procedure to a dynamic reconstruction. The objective of this study was to assess the improvement in facial symmetry and quality of life among older patients with flaccid facial palsy with the use of a plantaris tendon sling. Methods: A total of 46 patients who had undergone a static reconstruction with the plantaris tendon sling were studied. The surgical technique is detailed emphasizing the tips and pearls. Results: The displacement of the oral commissure was assessed with the FACIAL CLIMA demonstrating a mean elevation of 1.5 +/- 0.4 cm and an improvement of 97 +/- 7% in the recovery of oral commissure symmetry 2 years after the surgery, whereas the Sunnybrook Facial Grading System showed an improvement of symmetry at rest (-15 +/- 5) at 2 years. The Facial Disability Score indicated an improvement of the physical disability (+73.5 +/- 14) as well as the social impairment (+21 +/- 7) at 1 year postoperatively. Patients were followed for a median of 2 years (range 2-6 years). Conclusions: The use of tendon slings for static facial paralysis reconstruction is a reliable technique with no functional sequelae and good long-term results.
