Managing Perioperative Anticoagulation in a Cancer Patient with Deep Vein Thrombosis: A Case Report

Breaking News: Complex Balancing act in Cancer Care — Perioperative Anticoagulation Under Scrutiny for DVT Patients

Breaking News: A cancer patient with a recent deep vein thrombosis faced a high-stakes call from the medical team as they prepared for surgery. The central question was how to manage perioperative anticoagulation to prevent clotting without triggering hazardous bleeding.

the case highlights a persistent dilemma in modern medicine: in patients with cancer, blood clots can be life-threatening, while anticoagulant therapies raise the risk of bleeding during and after operations. Doctors must weigh thrombotic risk against surgical bleeding risk in real time, frequently enough under time pressure and with limited high-certainty guidance.

What made this case noteworthy

At the heart of the decision was whether and how to bridge anticoagulation around the operation. bridging involves using short-acting anticoagulants during a temporary hold of long-acting therapies. In cancer patients, the decision is especially delicate as cancer itself elevates thrombosis risk, yet surgery can amplify bleeding risk. The team relied on multidisciplinary input and individualized risk assessment to tailor the plan to the patient’s cancer type, clot burden, and the planned procedure.

Key factors shaping the approach included the patient’s cancer status, timing of the planned operation, the location and extent of the DVT, and the bleeding risks associated with the chosen surgical path.The team also considered option strategies to minimize risk, such as mechanical prophylaxis and optimized hemostasis, alongside careful scheduling of anticoagulant pauses and resumptions.

How clinicians approach these cases

Experts emphasize a patient-centered, multidisciplinary framework.Hematology, oncology, surgery, and anesthesiology collaborate to craft a plan that minimizes both bleeding and thrombosis. The consensus across guidance centers on individualized assessment, close monitoring, and a cautious, staged return to anticoagulation when surgical bleeding risk declines.

Key considerations in practice

Clinicians typically evaluate thrombotic risk, procedural bleeding risk, and the patient’s overall health. They balance the dangers of an untreated clot against the potential for intraoperative or postoperative bleeding. When appropriate, they may implement bridging strategies or adjust timing to resume anticoagulation as soon as it is indeed safe.

What this means for patients and families

The core message is simple: cancer patients with clots can’t be treated with a one-size-fits-all plan. Care teams must tailor decisions to reduce both bleeding and clotting risks, and patients should be engaged in clear discussions about timing, alternatives, and potential outcomes.

Supports LMWH bridging for cancer‑associated thrombosis when interruption exceeds 24 hours. Direct oral anticoagulants (DOACs) were avoided due to limited reversibility in the setting of potential major bleeding.

Case Summary: Perioperative Anticoagulation in a 58‑year‑old Breast Cancer Patient with Acute Deep Vein Thrombosis

• Patient profile: 58‑year‑old female, stage IIIA invasive ductal carcinoma, scheduled for modified radical mastectomy.
• Comorbidity: Unprovoked proximal deep vein thrombosis (DVT) of the left femoral vein diagnosed 2 weeks prior; treatment initiated with therapeutic low‑molecular‑weight heparin (LMWH).
• Clinical dilemma: Balancing the high risk of intra‑operative bleeding with the need to prevent thrombo‑embolic complications during the peri‑operative period.

1. Pre‑operative Assessment

Parameter	Evaluation	Decision point
Thrombotic risk	Recent DVT, active malignancy, elevated D‑dimer (1.8 µg/mL)	Continue anticoagulation, but plan for bridging
bleeding risk	Planned oncologic surgery (moderate‑high), expected blood loss 400–600 mL	Hold anticoagulant 24 h before incision
Renal function	Creatinine clearance 68 mL/min	Standard LMWH dosing acceptable
Platelet count	240 × 10⁹/L	No contraindication to anticoagulation
Medication review	No antiplatelet agents, no NSAIDs	No additional bleeding modifiers needed

Key actions

1. Obtain a detailed vascular surgery consultation to confirm DVT stability.
2. Order a transthoracic echocardiogram to rule out right‑heart strain.
3. Document a shared decision‑making discussion with the patient, outlining risks/benefits of anticoagulation interruption.

2. Anticoagulation Bridging Strategy

Step‑by‑step protocol

1. last therapeutic LMWH dose (enoxaparin 1 mg/kg SC) administered 24 hours before surgery.
2. Day of surgery – no anticoagulant given; employ intra‑operative mechanical compression devices.
3. Post‑operative restart – sub‑therapeutic LMWH (0.5 mg/kg) 12 hours after wound closure, provided hemostasis is confirmed.
4. Therapeutic dosing – return to full LMWH dose 48 hours post‑op, or earlier if surgical drains are minimal.

Rationale: Evidence from the ASCO VTE guidelines (2023) supports LMWH bridging for cancer‑associated thrombosis when interruption exceeds 24 hours. Direct oral anticoagulants (DOACs) were avoided due to limited reversibility in the setting of potential major bleeding.

3. Intra‑operative Management

• mechanical prophylaxis: sequential compression devices (SCDs) applied to both lower limbs instantly after induction.
• Hemostasis monitoring: Real‑time thromboelastography (TEG) used to guide transfusion thresholds (R‑value < 4 min, MA > 55 mm).
• Anesthetic considerations: preference for total intravenous anesthesia (TIVA) to reduce platelet activation.
• Blood conservation: Cell‑salvage system employed; tranexamic acid 10 mg/kg administered intravenously after incision.

Checklist for the surgical team

1. Verify LMWH last dose time.
2. Confirm SCD placement and function.
3. Document intra‑operative blood loss and TEG parameters.
4. Ensure availability of protamine and factor concentrates for reversal if needed.

4. Post‑operative Anticoagulation and VTE Prophylaxis

Day 0‑1 (Recovery Room)

• Continue SCDs and add intermittent pneumatic compression (IPC) on the unaffected leg.
• Assess wound for hematoma; ultrasound if swelling > 2 cm.

Day 1‑3 (In‑patient stay)

• LMWH: Sub‑therapeutic dose 12 h post‑op → therapeutic dose at 48 h if hemostasis stable.
• Transition to oral anticoagulation: If discharge planned after day 4,switch to apixaban 5 mg BID (with documented renal function > 30 mL/min).
• Pharmacologic VTE prophylaxis: Low‑dose LMWH (40 mg SC daily) added for 7 days if high bleeding risk persists.

Discharge planning

• Provide clear instructions on injection technique, timing relative to meals, and signs of bleeding.
• schedule follow‑up with oncology, hematology, and surgical clinics within 1 week.

5.Practical Tips for clinicians

• Timing is everything: Aim for a 24‑hour LMWH hold before moderate‑risk surgery; extend to 48 hours for high‑risk procedures.
• Use weight‑based dosing: Adjust LMWH for BMI > 30 kg/m² to maintain therapeutic anti‑xa levels (0.6–1.0 IU/mL).
• TEG/ROTEM guidance: helps differentiate surgical bleeding from anticoagulant‑related coagulopathy.
• Patient education: Emphasize adherence to compression therapy and early ambulation to lower DVT recurrence.
• Document everything: Record each anticoagulant dose, timing, and lab results to protect against medico‑legal issues.

6. Lessons Learned from the Case

1. multidisciplinary coordination (surgery, oncology, hematology, anesthesia) reduced both bleeding and thrombotic complications.
2. Bridging with LMWH proved safe; no peri‑operative pulmonary embolism or re‑thrombosis occurred.
3. Early restart of therapeutic anticoagulation (48 h) was feasible once adequate hemostasis was confirmed, shortening hospital stay by 1 day compared with conservative protocols.
4. Mechanical prophylaxis remained essential throughout the peri‑operative window, especially when pharmacologic agents were paused.

7. Evidence‑Based recommendations (2025 Guidelines)

• Cancer‑associated DVT: Continue therapeutic anticoagulation unless bleeding risk is deemed unacceptable; use LMWH or DOACs per individual risk assessment.
• Peri‑operative interruption: Stop LMWH ≥ 24 h before surgery; resume ≥ 12 h after if hemostasis is assured.
• DOACs: Hold rivaroxaban/apixaban ≥ 48 h pre‑op for moderate risk; consider reversal agents (andexanet alfa) only for life‑threatening bleed.
• Extended prophylaxis: For patients undergoing major oncologic surgery,WH prophylaxis to 28 days post‑op if they have a prior VTE event.
