Abstract
Background

Mechanical thrombectomy is a useful technique in patients with high-risk pulmonary embolism. It is indicated as an alternative to systemic fibrinolysis when it is contraindicated or as an adjuvant therapy when it fails.

Objective

To describe clinical characteristics, evolution and survival of patients with high-risk pulmonary embolism who have undergone mechanical thrombectomy.

Method

Single-center retrospective descriptive study of consecutive patients who underwent mechanical thrombectomy. Demographic, clinical and survival variables were analyzed.

Results

9 patients were included (56% men, 44% women). All patients had pulmonary artery pressure assessed using a Swan-Ganz catheter before thrombectomy. The median pulmonary artery pressure before the procedure was 46mmHg (51−38mmHg). Systemic fibrinolysis was also performed in 5 cases, in 2 of them in the setting of cardiorespiratory arrest, without hemorrhagic complications. No patient died during hospitalization. Survival one month after the procedure was 100%.

Conclusions

In our series, mechanical thrombectomy is a useful technique as an alternative to systemic fibrinolysis or as an adjuvant therapy to it.

Resumen
Antecedentes

La trombectomía mecánica es una técnica útil en pacientes con embolia pulmonar de alto riesgo. Está indicada como alternativa a la fibrinolisis sistémica cuando está contraindicada o como terapia adyuvante cuando esta fracasa.

Objetivo

Describir características clínicas, evolución y supervivencia de los pacientes con embolia pulmonar de alto riesgo a los que se les ha realizado trombectomía mecánica.

Método

Estudio retrospectivo descriptivo unicéntrico de pacientes consecutivos a los que se le realizó trombectomía mecánica. Se analizaron variables demográficas, clínicas y supervivencia.

Resultados

Fueron incluidos 9 pacientes (56% varones, 44% mujeres). A todos se les evaluó la presión en arteria pulmonar mediante catéter Swan-Ganz antes de la trombectomía. La mediana de presión arterial pulmonar previa al procedimiento fue de 46mmHg (51−38mmHg). Se realizó además fibrinolisis sistémica en 5 casos, en 2 de ellos en el seno de parada cardiorrespiratoria, sin complicaciones hemorrágicas. Ningún paciente falleció durante la hospitalización. La supervivencia al mes del procedimiento fue del 100%.

Conclusiones

En nuestra serie, la trombectomía mecánica resulta una técnica útil como alternativa a la fibrinolisis sistémica o como terapia adyuvante a esta.
