Venous thromboembolism after Diaphragm Pacing in amyotrophic lateral sclerosis

ABSTRACT Introduction: Patients with amyotrophic lateral sclerosis (ALS) are prone to venous thromboembolism (VTE) and secondary complications. Because there is an increased incidence of VTE after surgical procedures, placement of a Diaphragm Pacing System (DPS) in ALS patients as treatment for respiratory muscle weakness could potentially increase the incidence of VTE, especially in patients with limited mobility. Methods: We implanted a DPS in 10 ALS patients who met the criteria for this procedure. They underwent a preoperative evaluation as recommended by the guidelines. Results: We report 2 patients with no symptoms of deep vein thrombosis (DVT) before the surgical procedure who then developed perioperative VTE. Conclusions: These patients highlight the need to consider preoperative screening for DVT and postoperative thromboprophylaxis in high‐risk ALS patients who undergo DPS placement.
