Inhaled nitric oxide as an adjunct to suction thrombectomy for pulmonary embolism

J Vasc Interv Radiol. 2004 Nov;15(11):1311-5. doi: 10.1097/01.RVI.0000137979.63175.B6.


Pulmonary suction thrombectomy can be a successful interventional tool in the treatment of pulmonary thromboembolism. Removal of clot burden typically results in prompt recovery of hemodynamic stability and improved oxygenation. However, in rare cases, clot removal does not sufficiently improve the clinical situation. Herein, two patients with massive pulmonary thromboembolism are presented whose condition improved only after they received nitric oxide as an adjunct to pulmonary suction thrombectomy. The treatment with this inhalable vasodilator was based on the hypothesis that prolonged ischemia had induced microcirculatory vasospasm, persistent after removal of the central clot.
