Objective

Although surgical pulmonarythromboendarterectomy is the treatment of choice forpulmonary hypertension due to chronic thrombotic and/orembolic disease, minimally invasive endovasculartechniques such as angioplasty or placement of a metallicstent can provide acceptable results when surgery is notindicated or has been refused by the patient.

Patients and methods

Eight patients (5 men, 3 women;mean age, 62.6 years) were treated. The patients were in New York Heart Association (NYHA) class III or IV andhad a mean pulmonary artery pressure of 40 mm Hg ormore, a capillary wedge pressure of 15 mm Hg or less, and a Miller index greater than 0.5. In all cases, diagnosis was based on Doppler echocardiography, pulmonaryangiography, hemodynamic evaluation, and ventilation-perfusion scintigraphy. All patients received fibrinolytictherapy and underwent angioplasty. A metallic stent wasimplanted in 3 patients. Follow-up echocardiographicassessment and ventilation-perfusion scans were scheduledat 1, 3, 6, and 12 months.

Results

The procedures were technically successful in allcases. The mean follow-up period was 18.7 months. Minorcomplications were extrasystoles (3 cases), slight bruising atthe site of puncture (1 case), and rectal bleeding thatresolved without treatment (1 case). One patient died froman unknown cause 24 hours after the procedure. In all othercases, improvements were noted in NYHA functional class, in hemodynamics demonstrated by echocardiography, andin vascular structure as shown by arteriography andscintigraphy.

Conclusions

Minimally invasive endovascularinterventions can help improve pulmonary arterialhypertension due to chronic thrombotic and/or embolicdisease in patients for whom medical or surgical treatmentis not possible.

Objetivo

Aunque la tromboendarterectomía pulmonarquirúrgica es el tratamiento de elección en la hipertensiónarterial crónica de origen tromboembólico, cuando no hayindicación quirúrgica o el paciente rechaza la cirugía sepuede recurrir a técnicas endovasculares de mínima inva-sión (angioplastia y prótesis metálica) con aceptables resul-tados.

Pacientes y métodos

Se trató a 8 pacientes (5 varones y3 mujeres) con una media de edad de 62,6 años, en clase IIIo IV de la clasificación de la New York Heart Association(NYHA), con presión arterial pulmonar media de 40 mmHgo superior, presión capilar enclavada de 15 mmHg o menore índice de Miller mayor de 0,5. En todos los casos el diag-nóstico se estableció por ecografía Doppler cardíaca, angio-grafía pulmonar, estudio hemodinámico y gammagrafía deventilación-perfusión. Se realizó tratamiento fibrinolítico se-guido de angioplastia en todos los casos, y se colocó una pró-tesis metálica en 3. Se realizaron revisiones clínicas al cabode 1, 3, 6 y 12 meses mediante ecografía y gammagrafía.

Resultados

El éxito técnico del procedimiento fue del100%. El seguimiento medio fue de 18,7 meses. Como com-plicaciones menores se produjeron extrasístoles en 3 casos;hematoma leve en la zona de punción en un caso, y rectorra-gia, que remitió sin tratamiento, en otro. Una paciente mu-rió por causa desconocida al cabo de 24 h. En todos los casosrevisados se observaron una mejoría en la clasificación de laNYHA, mejora hemodinámica evidenciada por ecografía ymejora morfológica objetivada por arteriografía y gamma-grafía.

Conclusiones

Las técnicas endovasculares de mínimainvasión pueden contribuir a mejorar la hipertensión arte-rial pulmonar crónica debida a tromboembolia en la que noes posible otro tratamiento (farmacológico o quirúrgico).
