Management of cardiac tamponade during catheter-directed thrombolysis of saddle pulmonary embolism: A clinical dilemma

Abstract

Catheter-directed thrombolysis (CDT) for the treatment of acute pulmonary embolism (PE) has gained popularity in recent years, but potential complications during the procedure and their management are not frequently discussed in the literature. In this case report, we describe the clinical dilemma regarding the postoperative anticoagulation management of a 60-year-old male who developed cardiac perforation during a CDT of an acute saddle PE. Early resumption of systemic heparin in such cases may help in clot resolution; however, it can worsen the hemopericardium. On the other hand, delaying restarting heparin may help in healing of the cardiac perforation but can lead to clot propagation. As the chest tube output was minimal initially, anticoagulation was started, which, however, led to disastrous outcome. With limited published medical literature to help guide such a complex situation, it may be prudent to carefully weigh the risks and benefits of resuming systemic heparin versus delaying it for 1–2 days to allow for definitive resolution of the cardiac perforation.

Complicated Complication: How Interventional Radiologists Should Manage Acute Iatrogenic Cardiac Tamponade

“…Only one case of pericardiocentesis conducted by an interventional radiologist as an insidious emergency has been documented [9]. In this specific emergent case, the interventional radiologist was performing catheter guided thrombolysis of a saddle embolus when the operator had to perform a pericardiocentesis, subsequent to iatrogenic pericardial effusion.…”
