Management of post-biopsy hematomas requires individualization based on size, symptom severity, and progression trends. Standardized stepwise protocols prevent overtreatment while averting severe complications. Clinically, >90% resolve conservatively; only a minority require active intervention.
Hematoma evaluation involves three dimensions: ① Size: <2 cm (small), 2–5 cm (medium), >5 cm (large). ② Symptoms: Grade I (asymptomatic), Grade II (mild discomfort, no functional impairment), Grade III (severe pain, restricted activity). ③ Dynamics: Assess every 4 hours within 24 hours post-biopsy, then daily, monitoring for enlargement. Ultrasound is the primary tool, differentiating active bleeding via internal echoes and borders.
Conservative therapy suits Grade I–II small hematomas: ① Compression: Elastic bandages at 30–40 mmHg for 24–48 hours (avoiding circulatory compromise). ② Cryotherapy: Intermittent cold packs (15 min/hourly intervals) within 72 hours post-biopsy to constrict vessels. ③ Adjuvant pharmacotherapy: Oral Yunnan Baiyao capsules or tranexamic acid to promote coagulation. ④ Positioning: Avoid lateral decubitus on the affected side; elevate the head-of-bed 15° during sleep to reduce congestion. If hematomas enlarge >50%, skin warmth increases, or leukocytosis develops, infection is likely, warranting regimen adjustment.
Minimally invasive interventions target Grade III medium hematomas or conservative failures: ① Ultrasound-guided aspiration: For liquefied chronic hematomas; instill thrombin post-evacuation to induce clotting. ② Catheter drainage: For loculated hematomas; insert an 8F drain with continuous suction, irrigating daily until output <5 ml. ③ Endoscopic evacuation: For large hematomas with active bleeding; insert a 3-mm endoscope via a micro-incision to electrocoagulate vessels and clear clots. Regardless of modality, prophylactic antibiotics (e.g., cefuroxime axetil) for 3–5 days prevent secondary infection. For coagulopathic patients, correct INR to <1.5 preoperatively and extend compression to 72 hours post-biopsy. Future interventional radiology techniques, such as percutaneous vascular embolization, may offer novel solutions for refractory hematomas.
