Endostenting par prothèse en Y sur hématome après chirurgie de l’aorte thoracique

Abstract

Objective

To describe the diagnostic and therapeutic management of extrinsic tracheobronchial compression after thoracic aorta surgery.

Patient and methods

We report the case of a female patient with Marfan syndrome.

Results

A 27-year-old woman with Marfan syndrome presented respiratory distress after type III dissecting aneurysm of the descending aorta from extrinsic compression (hematoma) of the lower third of the trachea and the left bronchial stump. We placed a Y-stent (Y-Tracheobronxane^®, Novatech SA, France), thus restoring a satisfactory channel. A few days later, the patient developed right congestive heart failure from compression of the left pulmonary artery secondary to the progression of the hematoma. Medical treatment for this cardiological complication and the progressive resorption of the hematoma made it possible to remove the stent after 21 days with no dyspneic recurrence.

Conclusion

Placing a Y-stent is possible and effective and has few iatrogenic consequences in cases of extrinsic tracheobronchial compression from a hematoma occurring during heavy thoracic vascular surgery. With surgical revision impossible given the risks, stent placement allows progressive resorption of the hematoma, thus ending the compression of the bronchial tree.
