He came in complaining of chest pain and shortness of breath, expecting maybe a pulled muscle or a blood clot. Instead, scans revealed something almost unreal: a rigid rod of surgical cement running inside his heart and piercing his lung.
A routine back procedure ends in the cardiac theatre
The patient, 56, arrived at the emergency department with sharp chest pain that worsened when he breathed in, along with unusual breathlessness. Doctors see this kind of symptom every day. It often points to a lung infection, a collapsed lung or a classic blood clot in the lungs.
His chest X-ray, though, looked odd. On the image, emergency physicians spotted a long, extremely dense structure, far brighter than normal body tissue. A CT scan quickly followed and confirmed what they were seeing: a hard, straight object lodged in the right chambers of the heart. It did not look like a blood clot. It did not resemble a pacemaker lead or any standard piece of medical hardware.
Imaging revealed a 10-centimetre rod of orthopedic cement that had travelled from his spine into his heart, then penetrated his lung.
Cardiac surgeons were called in urgently. During open-heart surgery, they uncovered a sharp, rigid fragment of bone cement, about 10 cm long. It had pierced the right atrium of the heart and then the upper part of the right lung. The team removed the cement, repaired the heart tear and controlled the bleeding from the lung.
Remarkably, one month after the operation, the man’s symptoms had almost completely resolved. He survived an accident that could easily have ended in sudden cardiac arrest or massive internal bleeding.
What went wrong during his back surgery?
Just a week earlier, the man had undergone kyphoplasty, a common procedure used to treat painful vertebral compression fractures, often linked to osteoporosis. Both kyphoplasty and vertebroplasty involve injecting acrylic bone cement into a cracked or collapsed vertebra to stabilise it and ease pain.
The cement used is typically a polymethylmethacrylate (PMMA) mixture. It starts as a liquid paste. Surgeons or interventional radiologists inject it into the damaged bone under X-ray guidance. Within minutes, it hardens into a solid material that helps the spine bear weight more effectively.
During injection, though, some cement can escape through tiny veins inside the vertebra. From there, it can flow into larger veins that drain towards the heart. In many patients, small leaks occur but never cause trouble.

Studies suggest cement leakage into major veins in roughly one in four patients, yet only a very small fraction develop symptoms.
In this man’s case, some of the liquid cement entered the venous system, solidified into a narrow rod, and was carried by the bloodstream to the right side of the heart. The sharp fragment then behaved like a tiny spear, puncturing the heart wall and reaching the lung.
From spine to heart: the path of a cement embolism
Cement migration after spinal procedures is known as a cement embolism. When the fragment travels into the blood vessels, it can end up in:
- the right chambers of the heart
- the main pulmonary arteries
- smaller branches of the lung circulation
Many cement emboli settle in the lungs without causing any immediate problem. Sometimes they are spotted by chance on scans performed for another reason. But if the piece is large, pointed or poorly positioned, the risk rises sharply: the cement can block blood flow, damage vessel walls or, as in this case, perforate the heart.
How doctors spot and treat cement embolism
When cement reaches the lungs or heart, symptoms may look very similar to a standard pulmonary embolism caused by a blood clot. Patients can report:
- sudden chest pain, often sharp and worse on deep breathing
- shortness of breath or rapid breathing
- palpitations or rapid heartbeat
- feeling faint, weak or light-headed
- low blood pressure in severe cases
Because the warning signs mimic a clot, the key diagnostic tool is CT scanning. On CT images, bone cement appears as an extremely dense, bright material, almost like metal. This makes it easier to distinguish from soft blood clots.
A CT scan is usually the decisive test: cement stands out as a bright, rigid structure in the heart or pulmonary arteries.
Treatment depends on several factors: the size and shape of the fragment, where it is lodged, the patient’s symptoms and whether there is any bleeding or perforation.
Possible treatment strategies
Doctors can consider several options:
- Simple monitoring – for small, stable fragments that do not affect blood flow or cause symptoms.
- Endovascular removal – using catheters and tiny gripping devices threaded through veins to catch and pull out the cement.
- Open-heart surgery – often chosen when the cement has perforated the heart or major vessels, or when the patient is unstable.
In the reported case, open-heart surgery was judged the safest path because the cement had already torn the heart wall and lung tissue.
How rare is this complication after kyphoplasty?
Kyphoplasty and vertebroplasty are performed worldwide and have helped many patients regain mobility and manage severe spinal pain. The vast majority of procedures go smoothly. Leakage of tiny amounts of cement outside the vertebra is relatively frequent on imaging, but real complications remain uncommon.
Research suggests that visible venous leakage may occur in roughly 20–25% of treated patients, often without any symptoms. Only a small proportion develop a clinically significant cement embolism. Events where the fragment reaches the heart and perforates it, as in this man’s case, are particularly unusual and have been described mainly in case reports.
Serious intracardiac cement embolism is considered exceptional, yet it must be recognised quickly when chest symptoms appear after spinal cement procedures.
Because the technique is used on older adults, many of whom already have heart or lung conditions, clinicians face a challenge: separating routine post-operative discomfort from the early warning signs of an embolism.
Warning signs patients should not ignore
Anyone who has recently undergone a procedure using spinal cement should seek urgent medical advice if they notice:
- new or rapidly worsening chest pain
- unexpected shortness of breath, especially at rest
- sudden palpitations or irregular heartbeat
- unexplained fainting or near-fainting spells
- sharp back or shoulder pain linked to breathing
These symptoms do not automatically mean a cement embolism is present. They can be caused by a wide range of conditions, from muscle strain to heart attack. But after kyphoplasty or vertebroplasty, doctors tend to be more cautious and may order imaging to rule out cement migration.
Kyphoplasty, benefits and real-world risks
Kyphoplasty remains a valued tool for treating vertebral fractures. Patients who can barely stand due to spinal pain often report rapid relief once the cement stabilises the broken bone. The procedures are typically done through small skin punctures, with shorter recovery times than open spinal surgery.
Still, patients often do not hear much about rare complications. Cement leakage is one of those topics that sits in the background: known to specialists, barely mentioned in casual conversations about “routine” procedures.
| Aspect | Potential benefit | Potential risk |
|---|---|---|
| Pain relief | Rapid decrease in fracture pain | Occasional persistent pain |
| Spinal stability | Better support for collapsed vertebra | Cement leakage into nearby tissues or veins |
| Mobility | Improved ability to walk and function | Need for further procedures if new fractures occur |
| Cement embolism | Not a benefit, but usually avoided with technique | Rare migration of cement to lungs or heart |
Medical terms behind the headlines
Two phrases often appear in reports like this: “embolism” and “pleuritic pain”. They describe specific mechanisms and sensations.
An embolism means a material travelling through the bloodstream and getting stuck in a vessel. Usually, that material is a blood clot. In this story, it was solidified bone cement. Once lodged, an embolus can block blood flow and strain the heart.
Pleuritic pain is the sharp, stabbing chest pain that worsens when you breathe deeply, cough or laugh. It usually signals irritation of the pleura, the thin membranes lining the lungs and chest cavity. Emboli, infections and collapsed lungs can all trigger this type of pain.
What this case changes for patients and doctors
For patients, the story underlines a simple idea: if something feels wrong after a procedure, say so, even if it seems minor or embarrassing. Chest discomfort a week after back surgery is not always “just post-op pain”.
For doctors performing kyphoplasty or vertebroplasty, cases like this push towards meticulous technique: careful control of cement volume and pressure, constant imaging during injection, and close monitoring after the procedure. Some teams also review whether certain patients, such as those with large venous channels near the vertebra, need extra precautions.
In future, better cement formulations or delivery systems may further reduce leakage risk. Until then, cement embolism will remain a rare but striking example of how materials placed in the spine can, in exceptional circumstances, end up in the heart.
