Should I hold Eliquis (apixaban) for an acute iliacus psoas hematoma?

Management of Eliquis in Acute Iliopsoas Hematoma

Yes, you should immediately discontinue Eliquis (apixaban) for an acute iliopsoas hematoma, as this represents active bleeding requiring reversal of anticoagulation and conservative management until bleeding cessation is documented.

Immediate Anticoagulation Management

Discontinue Apixaban Immediately

• Stop Eliquis immediately upon diagnosis of the iliopsoas hematoma 1, 2, 3
• Iliopsoas hematoma is a recognized complication of anticoagulant therapy that requires prompt cessation of the offending agent 2, 3, 4
• The American Heart Association/American Stroke Association guidelines for hemorrhagic complications recommend withholding anticoagulants in patients with active bleeding 1

Consider Reversal Agents

• For patients with apixaban-associated bleeding, treatment with prothrombin complex concentrates (PCCs), FEIBA, or recombinant factor VIIa (rFVIIa) might be considered on an individual basis 1
• Activated charcoal might be used if the most recent dose of apixaban was taken less than 2 hours earlier 1
• The decision to use reversal agents depends on the severity of bleeding, hemodynamic stability, and size of the hematoma 1, 5

Initial Conservative Management Approach

Standard Conservative Therapy

• Conservative management is the first-line approach for most iliopsoas hematomas and includes bed rest, restoration of circulating volume, and correction of underlying coagulopathy 2, 5
• Monitor hemoglobin, hematocrit, and coagulation parameters closely 3, 6
• Provide adequate analgesia for severe pain, which is universally present 6

Imaging Confirmation

• CT scan is the most useful diagnostic modality for confirming iliopsoas hematoma and assessing size 2, 5
• Serial imaging may be needed to document stability or expansion of the hematoma 1, 5

Indications for Escalation of Care

When Conservative Management Fails

• Transcatheter arterial embolization should be considered for hemodynamically unstable patients or those with active bleeding 2, 4
• Surgical evacuation is indicated for patients with large hematomas causing significant femoral nerve compression with severe motor deficits 5, 6
• Femoral nerve palsy occurs in approximately 23-79% of cases and may require surgical decompression for optimal recovery 5, 6

Hemodynamic Monitoring

• Patients with hemodynamic instability require more aggressive intervention beyond conservative management 2, 5
• Monitor for signs of ongoing bleeding including declining hemoglobin, expanding hematoma on imaging, or worsening neurological deficits 3, 5

Timing of Anticoagulation Resumption

Documentation of Bleeding Cessation Required

• Do not resume anticoagulation until bleeding has definitively stopped, documented by stable hematoma size on imaging and stable hemoglobin levels 1
• The American Heart Association guidelines for intracerebral hemorrhage (applicable principles for other bleeding) suggest that after documentation of cessation of bleeding, anticoagulation may be considered after 1 to 4 days from onset 1
• For iliopsoas hematoma specifically, the timeline may be longer given the potential for rebleeding and need for complete hematoma stabilization 2, 5

Risk-Benefit Assessment for Resumption

• The decision to resume anticoagulation must weigh the thromboembolic risk (e.g., atrial fibrillation, recent VTE) against the bleeding risk 1
• Consider mechanical prophylaxis with intermittent pneumatic compression during the period when anticoagulation is held 1
• If the patient has a high thromboembolic risk and anticoagulation cannot be safely resumed, consider temporary IVC filter placement 1

Common Pitfalls to Avoid

Critical Errors in Management

• Never continue anticoagulation in the presence of active bleeding - this is the most common and dangerous error 2, 3, 4
• Do not resume anticoagulation prematurely before documenting bleeding cessation, as rebleeding can occur and may be life-threatening 3, 5
• Avoid underestimating the severity based on initial presentation - iliopsoas hematomas can expand rapidly and cause femoral nerve compression 5, 6
• Do not delay imaging if clinical suspicion is high, as early diagnosis improves outcomes 2, 5

Monitoring Considerations

• Femoral nerve function should be assessed regularly, as paralysis can develop early or late in the course 6
• The onset of femoral nerve symptoms typically occurs between day 3 and day 14 of anticoagulation therapy 6
• Excessive anticoagulation (supratherapeutic levels) is present in approximately 64% of cases, emphasizing the importance of appropriate dosing 6
