ATP Femoropoplítea en pacientes claudicantes*

Article information

Resumen

Objetivos

Valoración de los resultados a corto, medio y largo plazo de la Angioplastia Transluminal Percutánea (ATP) femoropoplítea en pacientes con isquemia crónica MsIs en grado II.

Pacientes y métodos

Estudio retrospectivo de 28 pacientes seleccionados por estenosis significativas u obstrucciones cortas (< 3cm) del sector femoropoplíteo, claudicantes, sometidos a ATP sobre 35 extremidades entre 1992 y 1997. (21 hombres-7 mujeres; Edad media 66 aíos).

Analizamos factores de riesgo, aspecto angiográfico pre y postprocedimiento, permeabilidad del procedimiento a 6, 14, 18, 32, 46 y 62 meses determinada por valoración clínica, funcional y Eco-doppler en el último año.

Resultados

Exito inicial en el 100% de los procedimientos, valorado por arteriografía post-ATP, clínica e índice T/B.

Complicaciones menores en 3 casos.

La permeabilidad fue analizada mediante tabla de supervivencia de Kaplan-Meier con los siguientes resultados: Permeabilidad primaria del 85.3%, 73.1%, 70.1%, 60.9%, 51.4% y 41.1% a 6, 14, 18, 32, 46 y 62 meses respectivamente. Permeabilidad asistida del 54,37% a 62 meses. Fueron necesarias 7 re ATP, 4 en los primeros 6 meses, 1 a los 12 meses y 2 a los 48 meses.

Conclusiones

La ATP en pacientes claudicantes de este sector puede ser beneficiosa en casos muy seleccionados por sus buenos resultados de permeabilidad a largo plazo. La clínica de claudicación reaparece en caso de obstrucción o reestenosis marcada.

Summary

Objetives

Valuation of Percutaneus Transluminal Angioplasty (PTA) femoropopliteal in patients with chronic ischaemia of lower limbs in degree II.

Patients and methods

Retrospective study of 28 patients selected by significant stenosis or short occlusions (< 3cm) of femoropopliteal sector, claudicants, to PTA on 35 extremities between 1992 and 1997. (21 men-7 women; Half age 66 years).

We analyze factors of risk, angiographic aspect before and after PTA, permeability of the procedure at 6, 14, 18, 32, 46 and 62 months determined by clinical, funtional valuation and Echo-doppler in the last year.

Results

Initial success in 100% of the procedures, valued by angiography after PTA, clinic and index T/B. Smaller complications in 3 cases.

The permeability was analyzed by means of chart of survival of Kaplan-Meier with the folloxoing results: Primary permeability of 85.3%, 73.1, 70.1%, 60.9%, 51.4% and 41.1% at 6, 14, 18, 32, 46 and 62 months respectively. Attended permeability of 54.37% to 62 months. They were necessary 7 rePTA, 4 in the first 6 months, 1 at the 12 months and 2 to the 48 months.

Conclusions

PT A in patients halting of this sector, it can be beneficial in cases very selected by their long term good permeability results. In case of re-stenosis or occlusions, claudication will return.
