Abstract
OBJECTIVE: To investigate if a history of venous thromboembolism (VTE) is a risk factor for complications in head and neck free flap surgery by assessing outcomes among patients with a history of deep vein thrombosis (DVT) and/or pulmonary embolism (PE). STUDY DESIGN: Retrospective cohort study. SETTING: Single tertiary care center. METHODS: All patients undergoing head and neck free flap reconstruction at our institution between September 1, 2006, and April 2, 2020, were assessed for inclusion. Patients with and without a history of DVT or PE preoperatively were identified and grouped for comparison. Groups were compared for demographics, comorbidities, and 30-day complications. Significance was assessed with chi-square and binary logistic regression analyses. RESULTS: Of the 1061 patients meeting inclusion criteria, 40 (3.8%) had a history of VTE. These patients were significantly older (mean [SD], years: 67.8 [11.7] vs 63.0 [14.1], P = .038) and significantly more likely to have history of chemotherapy (35.0% vs 18.7%, P = .010) and stroke (27.5% vs 4.5%, P < .001). After accounting for patient characteristics via binary logistic regression, VTE was independently associated with an increased risk for postoperative thrombosis of the free flap pedicle (odds ratio [95% CI] = 3.65 [1.12-11.90], P = .032) and reoperation (2.45 [1.25-4.80], P = .009). Patients with history of PE had a significantly increased risk for flap failure (7.70 [1.77-33.52], P = .007). Prior VTE was not independently associated with an increased risk for medical complications or readmission. CONCLUSION: Patients with a history of VTE may be at an increased risk for free flap compromise secondary to postoperative pedicle thrombosis. This risk should be considered in preoperative workup and postoperative monitoring.

Por qué esto importa para la hirudoterapia
Este estudio de cohorte retrospectivo de 1.061 pacientes con colgajos libres de cabeza y cuello encontró que el antecedente preoperatorio de tromboembolismo venoso se asoció de forma independiente con un mayor riesgo de trombosis postoperatoria del pedículo del colgajo libre (OR 3,65) y de reintervención (OR 2,45), mientras que el antecedente de embolia pulmonar específicamente aumentó el riesgo de fallo del colgajo (OR 7,70). La conexión con el ámbito de la ASH es indirecta: el estudio se refiere a complicaciones trombóticas en reconstrucción microvascular, un contexto clínico en el que las sanguijuelas medicinales se utilizan a veces para el rescate del colgajo en la congestión venosa. Sin embargo, el artículo no menciona sanguijuelas, hirudoterapia ni compuestos derivados de sanguijuelas. Ningún contenido respalda una relevancia directa más allá del dominio quirúrgico compartido donde la terapia con sanguijuelas puede ser una herramienta coadyuvante.
