O86.81 Puerperal septic thrombophlebitis

Name of the Condition

• Puerperal septic thrombophlebitis (O86.81)

Summary

Puerperal septic thrombophlebitis is a postpartum infection involving inflammation and clot formation in the veins, typically occurring within the pelvic or lower extremity venous system. This condition requires prompt recognition and treatment to prevent systemic complications.

Causes

The condition arises from bacterial infection of the venous system during the puerperium, often following childbirth. Common pathogens include Staphylococcus aureus, Streptococcus species, and anaerobic bacteria. Infection may originate from nearby pelvic tissues or spread hematogenously.

Risk Factors

• Prolonged labor or membrane rupture
• Cesarean delivery
• Retained placental fragments
• Multiple vaginal examinations during labor
• Preexisting infections (e.g., chorioamnionitis)
• Immunosuppression or underlying medical conditions
• History of venous thromboembolism

Symptoms

• Fever (temperature >38°C or 100.4°F)
• Localized pain, swelling, or warmth over affected veins
• Erythema (redness) along the vein
• Malaise or fatigue
• Possible palpable cord-like vein
• In severe cases, signs of sepsis (e.g., tachycardia, hypotension)

Diagnosis

Diagnosis involves clinical evaluation of symptoms, physical examination (e.g., palpation of tender, inflamed veins), and imaging studies (e.g., ultrasound or Doppler) to confirm venous thrombosis. Blood cultures may identify the causative organism.

Treatment Options

Treatment typically includes broad-spectrum antibiotics to target the infection and anticoagulation to prevent clot extension. Severe cases may require hospitalization for intravenous therapy and monitoring. Surgical intervention is rarely needed.

Prognosis and Follow-Up

With prompt treatment, most patients recover fully. Follow-up may involve monitoring for resolution of symptoms and assessing for complications like pulmonary embolism. Anticoagulation duration depends on clot extent and risk factors.

Complications

• Pulmonary embolism from clot migration
• Sepsis or septic shock
• Chronic venous insufficiency
• Post-thrombotic syndrome
• Recurrent thrombosis

Lifestyle & Prevention

• Maintain good perineal hygiene post-delivery
• Early ambulation to promote circulation
• Proper wound care after cesarean or episiotomy
• Avoid prolonged immobility
• Seek prompt care for signs of infection

When to Seek Professional Help

Consult a healthcare provider immediately if experiencing fever, severe leg pain, swelling, or signs of sepsis (e.g., rapid heart rate, confusion) after childbirth.

Tips for Medical Coders

Document the presence of venous thrombosis and associated infection clearly. Include details on affected veins (e.g., pelvic, lower extremity) and any confirmed pathogens. Ensure documentation supports the septic nature of the thrombophlebitis to justify the code.
