Nonpharmacologic Thrombectomy

Most cases of VTE can be successfully treated with anticoagulation. In some cases, removal of the occluding thrombus by surgical intervention may be warranted. Surgical or mechanical thrombectomy can be considered in patients with massive iliofemoral DVT when there is a risk of limb gangrene due to venous occlusion. The procedure can be complicated by recurrence of thrombus formation. In patients who present with massive PE, pulmonary embolectomy can be performed in emergency cases when conservative measures have failed. Patients who are hemodynamically unstable and have a contraindication to thrombolysis are candidates for pulmonary embolectomy. Administer heparin by IV infusion to achieve a therapeutic aPTT during the operation and postoperatively. Thereafter, give warfarin for the usual recommended duration.17,23

Vena Cava Interruption

IVC interruption is indicated in patients with PE who have a contraindication to anticoagulation therapy and in patients who have recurrent VTE while taking anticoagulation therapy.17' IVC interruption is accomplished by inserting a filter through the internal jugular vein or femoral vein and advancing it into the IVC using ultrasound or fluoroscopic guidance. IVC filters reduce the short-term risk of PE, but this benefit is not sustained in the long term. The incidence of DVT at 1 year after IVC filter insertion is higher when compared to patients without filters. Survival after a PE is

no different in patients with filters versus patients without filters. Therefore, anticoagulation therapy should be resumed as soon as possible after filter insertion and

continued as long as the filter is in place due to the high risk of DVT. Temporary or removable filters are now increasingly used and are replacing the use of permanent filters.17
