Septic Thrombophlebitis Treatment & Management

Prehospital Care
No specific prehospital care is required for septic thrombophlebitis.
Emergency Department Care
Peripheral
Peripheral intravenous catheters should be removed at the first sign of erythema, induration, or edema.[3] The temptation to try to preserve a peripheral intravenous catheter must be resisted, because complications associated with septic phlebitis are substantial and increase dramatically over time if the catheter is left in place.
Once phlebitis has become suppurative, simply removing the cannula is no longer sufficient. Inpatient surgical resection of the involved vein and its emissaries is the treatment of choice. Broad-spectrum antibiotics to cover S aureus, streptococci, and Enterobacteriaceae should be administered if suppuration or infection are noted. Polymicrobial infections are particularly common in burn patients.
Associated abscesses should be incised and drained.
Central
In contrast to peripheral venous catheters, infected central venous catheters should not be removed precipitously. Infected and thrombosed central catheters often have an extensive infected free-floating fibrin sheath, and a large mass of septic thrombus may be attached to the catheter. If the catheter is withdrawn precipitously, this septic material may embolize to cause infarct and distant septic metastases. Fibrinolysis is often necessary before safe removal can be undertaken.
Broad-spectrum antibiotics are indicated. In the case of Lemierre's syndrome, particular attention should be paid to covering anaerobic infections, whereas intra-abdominal septic thrombosis requires coverage of gram-negative organisms and anaerobes. Duration of therapy for all central venous disease is usually 4-6 weeks. Because many infections are due to S aureus, coverage of MRSA should be seriously considered depending on local resistance patterns.
Anticoagulation with heparin has been recommended for most central venous thrombophlebitides. The course of septic pelvic thrombophlebitis is notably improved with anticoagulation,[35] though there is no proven benefit in pylephlebitis. Its role in Lemierre's syndrome also remains controversial.[11] Anticoagulation does have an associated benefit in dural sinus thrombophlebitis, but no prospective data exist.[11]
Surgical excision of the involved vein is not possible in these cases, but resection of the infected thrombus may sometimes be necessary as an inpatient if the patient does not respond to medical management.
Associated abscesses should be incised and drained, surgically if in the deep tissues.[10, 15]
Consultations
- Surgery/vascular: Well-localized superficial phlebitis, even if suppurative, does not require any consultation provided the emergency physician is capable of performing superficial phlebectomy if indicated. However, patients with widespread suppurative phlebitis or suppurative phlebitis threatening the deep venous system benefit from consultation with a vascular surgeon. Additionally, the expertise of a general surgeon, gynecologist, otorhinolaryngologist, or neurosurgeon may be indicated, depending on each patient’s focus of infection and metastatic spread.
- Interventional radiology: Patients with thrombosed and infected central lines benefit from fibrinolysis and antibiotics prior to removal of the catheter. Because emergency physicians cannot often carry out this fibrinolysis due to hospital-specific time and expertise constraints, consultation with an interventional radiologist may be indicated.
- Infectious disease: Consultation with an infectious disease specialist may be prudent, in particular when dealing with immunocompromised patients.
- Intensive care: ICU consultation is required when clinically warranted.
