Summary
Low molecular weight heparin (LMWH) prophylaxis can lead to rectus sheath hematoma, a rare complication. Early diagnosis and management are crucial, especially during surgery, to prevent severe outcomes like hypovolemic shock.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Anesthesiology
Background:
- Low molecular weight heparins (LMWH) are standard for preventing thromboembolic events.
- Rectus sheath hematoma is a rare but serious complication associated with LMWH therapy.
- Transsphenoidal surgery for hypophysial adenoma carries its own set of risks.
Observation:
- A patient undergoing transsphenoidal surgery for a hypophysial adenoma developed hypotension during LMWH prophylaxis.
- The patient's condition progressed to hypovolemic shock with atrial fibrillation.
- Computed tomography confirmed a large rectus sheath hematoma.
Findings:
- Conservative management led to the resolution of the rectus sheath hematoma and stabilization of the patient.
- Delayed diagnosis of rectus sheath hematoma can complicate intraoperative management and lead to severe hemodynamic instability.
- Spontaneous rectus sheath hematoma presentation is often nonspecific, necessitating advanced imaging for diagnosis.
Implications:
- Highlights the importance of vigilance for rare LMWH complications, even in elective surgical settings.
- Emphasizes the need for early recognition and management of rectus sheath hematoma to prevent surgical complications.
- Suggests that pre-operative diagnosis and management of rectus sheath hematoma could significantly improve patient outcomes and surgical safety.
