Will You Need a Blood Transfusion for Disc Replacement?

No, you do not always need a blood transfusion for disc replacement because it is a less invasive procedure that limits blood loss. However, you may need a blood transfusion if you have anemia or undergo multi-level spine surgery, as longer procedures can lead to higher blood loss.

At Total Orthopedics and Sports Medicine, our surgeons use an advanced approach to minimize blood loss during surgery. We also use camera-guided techniques such as fluoroscopy to target the surgical area and avoid tissue damage. This method helps control bleeding, supports faster healing, and promotes a smooth recovery. Call 855-321-6784 for an advanced surgery.

How Common Is a Blood Transfusion During Disc Replacement?

A blood transfusion during disc replacement is very rare, especially in single-level procedures. In fact, a retrospective study published in Springer found that none of the patients required donor blood during the procedure. In this study, the researchers analyzed 50 patients who underwent lumbar disc replacement. They found that around 96% of cases had very low blood loss of about 119 mL.

After a 30-day follow-up, only 8.5% of patients were readmitted, and one patient visited the emergency department but returned home after normal test results. Research also found that no patients were readmitted due to postoperative anemia. However, the need for a blood transfusion varies and depends on the following predictors:

Surgical Approach (Anterior vs. Posterior)

An anterior approach (from the front) is often more efficient and allows better access to the disc, which can help control blood loss. In contrast, a posterior approach (from the back) avoids major blood vessels but still requires careful handling of soft tissues. Research published in the Life Journal shows that this approach can lead to higher blood loss due to larger incisions and longer surgical time.

Number Of Levels Treated

If surgeons treat only one level, the procedure takes less time and usually leads to minimal blood loss. However, in multi-level surgery, the need for a blood transfusion may increase because the procedure requires a longer operative time and dissection. For example, a study published in the International Journal of Spine Surgery compared 86 patients who underwent disc replacement at one level (54 patients) and at two levels (32 patients).

The study found that single-level cases had lower blood loss, around 59 mL, compared to about 79 mL in two-level procedures. It also showed that operative time was shorter in single-level cases (61.6 minutes) than in two-level procedures (97.8 minutes). In addition, patients with single-level surgery had a shorter hospital stay of 1.89 days compared to 2.44 days.

Surgical Setting (Outpatient vs. Hospital)

The need for a blood transfusion during disc replacement surgery is significantly lower in the outpatient setting than in traditional hospital settings. This happens because outpatient procedures usually involve carefully selected patients and less complex cases. Beyond that, NIH research shows that 90-day readmission rates are lower in outpatients than inpatients. It also found that anterior lumbar procedures, including single-level and multilevel cases, can be performed safely in an outpatient setting.

Can Anemia Increase Transfusion Risk in Disc Replacement?

Yes, anemia can increase the risk of a blood transfusion during disc replacement. This condition lowers the number of red blood cells, which reduces oxygen supply to tissues and can affect organ function during surgery. Surgical stress also triggers inflammation and limits the body’s ability to restore blood levels after loss. For this reason, your healthcare provider evaluates your condition through tests to confirm and manage anemia before spinal surgery.

Anemia can also lead to postoperative complications by reducing oxygen delivery to healing tissues. As a result, you may face a higher risk of infection symptoms, including wound issues and pneumonia. In addition, the heart and lungs may strain, leading to problems such as irregular heart rhythms or breathing difficulties. This reduced oxygen supply can also affect the kidneys, potentially impairing leg circulation and delaying recovery.

Note: You should check your red blood cell count (hemoglobin levels) 4 to 6 weeks before surgery to detect and treat underlying anemia.

What Is The Average Blood Loss Range In Lumbar ADR?

The average blood loss for lumbar artificial disc replacement is typically around 50–150 mL in single-level procedures. However, if you undergo a two-level procedure or if vascular injury occurs, the total blood loss can increase to around 200–300 mL. This happens because a longer surgical time can lead to increased bleeding during the procedure.

Moreover, a prospective NIH study evaluated 290 patients who underwent 404 lumbar disc replacements to assess outcomes and surgical factors. Among these, 27 patients had prior fusion surgery and were followed for an average of 33 months. The study found that disc replacement required less operative time and resulted in lower blood loss than more complex fusion procedures. It also reported an average estimated blood loss of about 290 mL, even in more complex cases. Beyond that, the study reported the following clinical outcomes after disc replacement surgery:

• Surgery Duration: About 134 minutes on average
• Hospital Room Stay: Around 3.3 days
• Return to Work: About 32 days after surgery
• Pain Level: Reduced from 9.1 to 3.2 after surgery
• Disability Score (ODI): Improved from 50.2 to 21.7
• Reoperation: 4 patients needed revision surgery

Why Is Blood Loss Generally Lower In Spine Surgery?

Blood loss is generally lower in disc replacement surgery because it is a less invasive procedure. This technique uses an anterior (front) approach, which avoids incision through back muscles and reduces tissue damage. Other than that, the ADR procedure usually treats only one level and takes less time, which helps limit bleeding. Unlike fusion surgery, it also requires less muscle dissection and avoids extensive hardware placement, which further reduces blood loss.

What Techniques Do ADR Surgeons Use To Minimize Blood Loss?

Our surgeon, Dr. Georgiy Brusovanik, MD, uses a minimally invasive anterior approach and pharmacologic agents, such as tranexamic acid (TXA), to significantly reduce bleeding during ADR procedures. He may also use advanced electrosurgical devices, which allow precise cutting while sealing blood vessels. In some cases, he may apply topical hemostatic agents directly to the surgical site to support natural clot formation after careful physical exam.

Here are common topical hemostatic agents that Dr. Georgiy Brusovanik, MD, may use to control bleeding during ADR procedures:

Flowable Hemostats (Thrombin-Gelatin Matrices)

These agents quickly control active bleeding by adapting to the shape of the surgical site and forming a stable clot. For example, an NIH study shows that Floseal (Baxter) combines human thrombin (a protein that helps blood clot) with a gelatin matrix to stop moderate to severe epidural bleeding (bleeding around the spinal cord covering). Similarly, Surgiflo (Ethicon) uses a gelatin-thrombin blend to create a strong clot barrier that controls bleeding throughout the procedure.

Oxidized Regenerated Cellulose (ORC)

Our surgeons use this absorbable topical agent to control bleeding from small blood vessels when standard methods like electrocoagulation are less effective. The doctor applies it in a dry or slightly moistened form, which helps stop slow bleeding from veins and small arteries. Moreover, a recent PubMed systematic review found that ORC reduced total blood loss by about 102.5 mL compared to standard methods. It also reduced the hemoglobin drop by nearly 4 g/L (a measure of blood loss) without increasing surgical risk.

Gelatin Sponges or Powders

Gelatin-based materials help control bleeding by absorbing blood and gently pressing against the bleeding area. Surgeons often place them in the epidural space to control venous bleeding without risking nearby nerves connected to the thoracic and lumbar regions.

Besides reducing blood loss, gelatin materials also provide the following benefits during surgery:

• Epidural Hemostasis: They control bleeding in sensitive spinal areas where heat-based tools may damage nerves.
• Bone Surface Control: Products such as Gelfoam or Surgifoam are commonly applied to cancellous bone (spongy inner bone) and are absorbed within 4–6 weeks.
• Adhesion Prevention: They help reduce the formation of fibrous tissue (scar-like tissue) that can stick to nerve roots after surgery.

Moreover, Dr. Georgiy Brusovanik, MD, may use cell-salvage systems to collect and clean your blood during the procedure via intravenous methods. This approach helps maintain your blood volume and reduces the need for donor transfusions (blood from another person). In severe cases, he will guide you to store your own blood through autologous donation (using your own blood).

What Factors Can Increase Bleeding During ADR?

Old age, higher body mass index (BMI), and multilevel procedures affect the spinal joints and increase the risk of blood loss during surgery. Research in the North American Spine Society Journal reports that the type of prosthesis and intraoperative heparinization are also associated with increased bleeding. Beyond that, continuing low-dose aspirin (LD-ASA) may affect bleeding control during the procedure.

Here is how these factors increase the risk of bleeding during ADR procedures:

Prosthesis Type (TDR)

Certain disc implant designs require wider surgical exposure, which increases the chance of bleeding. In such cases, surgeons often need to prepare the disc space more extensively, including keel cuts (grooves cut into bone to secure the implant). This process exposes cancellous bone (spongy inner bone), which tends to bleed more than hard outer bone. As a result, procedures may result in greater overall blood loss.

Intraoperative Heparinization

Spine specialists use heparin (a blood thinner) during surgery to prevent clot formation when blood vessels are retracted. This step protects you from serious complications, such as thromboembolism (blood clots that move through blood vessels). However, heparin reduces the blood’s ability to clot, which can increase bleeding during the procedure.

Increased BMI

According to NIH research, patients with a BMI of 25 kg/m² or higher tend to experience greater blood loss and longer surgical times than those of normal weight. The study also found that the risk of perioperative complications (issues during or after surgery) increases when BMI rises above 22.3 kg/m². It further showed that the risk of durotomy (tear in the spinal covering) becomes higher when BMI exceeds 25.1 kg/m². This happens because higher BMI (excess body weight) limits clear visibility of the surgical area. In such cases, surgeons often need stronger retraction (pulling tissues aside), which can increase pressure on blood vessels. This pressure raises the risk of swelling and bleeding during the procedure.

Anatomical Variations

Variations in blood vessel positioning can make the procedure more complex. For example, a low bifurcation (early splitting) of the aorta or vena cava requires additional dissection (careful tissue separation). For this reason, surgeons gently move and hold these vessels aside to safely reach the spine. This manipulation increases the risk of bleeding during the procedure.

Does Age Impact Blood Loss in ADR?

Yes, older patients may experience more bleeding during artificial disc replacement (ADR). This happens because aging reduces the strength of perivascular connective tissue (tissue that supports blood vessels). As a result, smaller blood vessels become more fragile and bleed more easily during surgery. In addition, the following age-related conditions (other health issues) can further increase the overall risk of blood loss during the procedure.

• Hypertension (high blood pressure): Higher pressure in the vessels can increase bleeding during surgery.
• Diabetes: Slower healing can increase the risk of bleeding.
• Atherosclerosis (hardened arteries): Reduced flexibility makes vessels more prone to injury.
• Chronic kidney disease: It can affect clotting function and increase bleeding risk.
• Liver disorders: They reduce the production of clotting factors (proteins that help stop bleeding).

In fact, a study published in the Global Spine Journal shows that older patients face a higher risk of complications during spinal surgery. The study reviewed 262 surgeries in patients aged 80 years or older across multiple centers. It found that complications occurred in about 29% of cases, with 13% classified as life-threatening. The results also showed that blood loss of 500 g or more significantly increased the risk of surgical complications.

What Are the Risks of Blood Transfusion During ADR?

Blood transfusion during ADR can lead to complications such as surgical site infections (SSIs) and acute respiratory distress. It can also cause acute immune hemolytic reactions, febrile reactions (fever and chills), and allergic reactions ranging from mild itching to severe issues. Beyond that, you may develop delayed immunomodulation (weakened immune response) or transfusion-associated circulatory overload (TACO) due to excess fluids.

In some cases, the following complications may also occur due to blood transfusion:

• Transmission of infectious diseases: You have a risk of viruses like HIV or Hepatitis B/C despite strict screening.
• Thrombotic Events: Blood transfusions are linked to a higher risk of deep vein thrombosis (DVT) and pulmonary embolism
• Longer Hospital Stay: Transfusion is associated with higher complication rates, often leading to increased hospital length of stay (LOS).
• Iron overload: Excess iron from repeated transfusions can build up and damage organs over time.

How Long Does It Take to Recover Blood Loss After ADR?

Most patients begin to recover from blood loss within 2 to 4 weeks, while full recovery after ADR can take 3 to 6 months. In the first few days after surgery, hemoglobin levels (a measure of the amount of blood in your body) usually drop and reach their lowest point around days 3 to 4. After this phase, your body gradually restores blood levels during the first week and continues recovery within a few months. However, the exact duration of recovery varies depending on the following factors:

• Blood Loss Amount: Less blood loss supports faster recovery.
• Nutrition: Good iron intake helps rebuild blood quickly.
• Surgical Approach: Minimally invasive methods reduce bleeding.
• Post-op Care: Avoiding NSAIDs prevents hidden bleeding.
