Insights
Immediate groin hematomas after electrophysiologic (EP) procedures predict later hematoma development. Focusing on procedural techniques and post-procedure care is key to preventing these common complications.
Area of Science:
- Cardiology
- Electrophysiology
- Vascular Access
Background:
- Groin hematomas are a common complication following electrophysiologic (EP) procedures.
- Understanding the incidence and predictors of these hematomas is crucial for improving patient outcomes.
Purpose of the Study:
- To evaluate the incidence and identify predisposing factors for groin hematomas after EP procedures.
- To determine the relationship between immediate post-procedural hematomas and later patient-reported hematomas.
Main Methods:
- Prospective observational study of patients undergoing EP procedures for various arrhythmias.
- Standardized manual compression, bed rest, and specific anticoagulation protocols were used.
- Adhesive pressure dressings were applied based on specific procedural criteria; hematomas were assessed via telephone follow-up.
Main Results:
- The overall incidence of hematoma was 10% immediately post-procedure and 27% at 14 days.
- No significant association was found between hematoma and factors like sex, age, BMI, anticoagulation levels, or use of pressure dressings.
- Immediate post-procedural hematoma was a strong predictor of patient-reported hematoma at 14 days (OR 18.7).
Conclusions:
- Immediate groin hematoma is the primary predictor of subsequent hematoma development after EP procedures.
- Preventive strategies should target both the procedural phase and immediate post-procedural care to minimize hematoma risk.
Objectives:
We evaluated the incidence and predisposing factors of groin hematomas after electrophysiological (EP) procedures.
Design:
Prospective, observational study, enrolling consecutive patients after EP procedures (Atrial fibrillation: n = 151; Supraventricular tachycardia/Diagnostic EP: n = 82; Ventricular tachycardia: n = 18). Patients underwent manual compression for 10 min and 3 h post procedural bed rest. AF ablations were performed with INR 2-3, ACT > 300, and no protamine sulfate. Adhesive pressure dressings (APDs) were used if sheath size ≥ 10F; procedural time > 120 min; and BMI > 30. Patient-reported hematomas were recorded by a telephone follow-up after 2 weeks.
Results:
Hematoma developed immediately in 26 patients (10%) and after 14 days significant hematoma was reported in 68 patients (27%). Regression analysis on sex, age, BMI 25, ACT 300, use of APD, sheath size and number, and complicated venous access was not associated with hematoma, either immediately after the procedure or after 14 days. Any hematoma presenting immediately after procedures was associated with patient-reported hematomas after 14 days, odds ratio 18.7 (CI 95%: 5.00-69.8; P < 0.001).
Conclusions:
Any hematoma immediately after EP procedures was the sole predictor of patient-reported hematoma after 2 weeks. Initiatives to prevent groin hematoma should focus on the procedure itself as well as post-procedural care.
