Comparison of atherectomy, drug-eluting balloon, and combined treatment efficiency by near infrared spectroscopy.

La aterosclerosis es una patología sistémica que afecta a todo el sistema vascular. El tabaquismo, la hiperlipidemia, la diabetes mellitus, la edad avanzada y la hipertensión son factores de riesgo conocidos para el desarrollo de aterosclerosis. El tratamiento quirúrgico en la enfermedad arterial periférica ha sido reemplazado por opciones de tratamiento endovascular en los últimos años debido a la mortalidad y la morbilidad. En nuestro estudio, nuestro objetivo fue presentar la efectividad de la aterectomía, el balón liberador de fármacos y la terapia combinada con valores determinados por espectroscopía de infrarrojo cercano en pacientes con enfermedad arterial periférica aterosclerótica. Material y métodos: Los pacientes con claudicación intermitente o isquemia crítica de la pierna (Rutherford clase 3 o más) han sido vistos en el estudio. Hubo 30 pacientes masculinos y 9 femeninos. Los pacientes fueron seguidos antes, en la primera hora después y en el tercer mes después del procedimiento, con un índice simultáneo de presión tobillo-brazo (ABI), mediciones de la distancia a pie y medición de la oxigenación de los tejidos mediante el método de espectroscopía de infrarrojo cercano (NIR). Resultado: cuando los pacientes con mediciones similares de ABI postoperatorio se evaluaron con NIR, se observó una mayor oxigenación venosa en los pacientes que usaron métodos de tratamiento combinados con aterectomía. Según estos resultados, pensamos que los métodos de tratamiento combinados con aterectomía han aumentado la mirocirculación y la circulación colateral más que otros métodos. Atherosclerosis is a systemic pathology involving the entire vascular system. Smoking, hyperlipidemia, diabetes mellitus, advanced age, and hypertension are known risk factors for the development of atherosclerosis. Surgical treatment in peripheral arterial disease (PAD) has been replaced by endovascular treatment options in recent years due to mortality and morbidity. In our study, we aimed to present the effectiveness of atherectomy, drug-eluting balloon, and combined therapy with values determined by near-infrared spectroscopy (NIRS) in patients they have atherosclerotic PAD. Materials and methods: Patients with intermittent claudication or critical leg ischemia (Rutherford class 3 or more) have been viewed in the study. There were 30 male and 9 female patients. Patients were followed up before, at the 1st h after and at the 3rd month after the procedure, with simultaneous ankle-brachial pressure index (ABPI), walking distance measurements, and measurement of tissue oxygenation by NIRS method. Results: When patients with similar post-operative ABPI measurements were evaluated with NIRS, venous oxygenation was observed higher in patients used treatment methods combined with atherectomy. According to these results, we thought that treatment methods combined with atherectomy have increased microcirculation and collateral circulation more than other methods.
