Removal of intracardiac bone cement embolism after percutaneous kyphoplasty: A case report

Cement leakage and pulmonary embolism by bone cement-augmented pedicle screw fixation of the thoracolumbar spine - A case report

Background

Few studies discuss the complication of pulmonary cement embolism (PCE) due to cement augmented pedicle screw instrumentation (CAPSI) of the thoracolumbar spine.

Case Description

A 62 female with a history of multiple myeloma and Sjogren's syndrome on chronic steroids developed an osteoporotic L1 compression fracture and underwent posterior stabilization with a T10-L4 CAPSI. However, postoperatively, the patient developed a surgical site infection and a PCE, resulting in severe respiratory compromise and death 1 month later.

Conclusion

When performing a T10-L4 thoracolumbar CAPSI (i.e., augmented pedicle screw instrumentation of the thoracolumbar spine) to address an L1 osteoporotic compression fracture, a 62 year old patient developed a life ending multi organ deficiency due to sepsis together with a PCE.

Case report: Inspiration from a rare fatal heart perforation after percutaneous vertebroplasty

The principal benefit of employing percutaneous vertebroplasty (PVP) for managing osteoporotic vertebral compression fractures lies in its capacity to facilitate early mobilization in elderly patients, thereby effectively avoiding the potential catastrophic complications associated with prolonged bedridden states. However, bone cement leakage, as the most common complication of PVP, may have fatal consequences. Here, we report a case involving an 85-year-old male patient with L1 vertebral compression fracture who underwent PVP at our hospital and was discharged on the same day of the surgical intervention. Subsequently, the patient experienced symptoms of chest tightness and palpitations. Cardiac ultrasound examination revealed pericardial effusion, while pulmonary computed tomographic angiography (CTA) demonstrated a strip high-density shadow in the right ventricular area. Finally, it was determined that the perforation of the right ventricular wall was caused by bone cement embolism. Through this comprehensive case report, we aim to deepen the understanding of orthopedic doctors on the importance of preventing bone cement leakage.

Life-threatening intracardiac cement embolisms after percutaneous kyphoplasty: a case report and literature review

BACKGROUND

Percutaneous kyphoplasty is a popular technique in the treatment of osteoporotic vertebral fractures, but intracardiac cement embolism can be a life-threatening complication.Case presentation: The authors present a case involving a patient who developed dyspnea and chest tightness after percutaneous kyphoplasty. Echocardiography and chest computed tomography confirmed several foreign bodies in the right atrium and pulmonary arteries causing cardiac perforation and pericardial tamponade. Conservative treatment was administered, and the patient died of respiratory and heart failure.

CONCLUSIONS

The present case highlights that surgical removal may be the first-choice treatment for symptomatic intracardiac cement embolism.

A case report of intracardiac bone cement embolization after posterior decompression and cement-enhanced pedicle screw fixation for osteoporosis and lumbar degeneration

RATIONALE

Bone cement leakage is a common complication of percutaneous kyphoplasty (PKP) and percutaneous vertebroplasty (PVP) surgery and has also been reported in posterior decompression and cement-enhanced pedicle screw fixation. When bone cement leaks through the venous system, it will have serious consequences and even endanger the life of the patient, especially when the bone cement causes intracardiac embolism.

PATIENT CONCERNS

A 70-year-old woman developed chest tightness and decreased blood oxygen saturation following posterior decompression and cement-enhanced pedicle screw fixation.

DIAGNOSIS

After the patient was given symptomatic treatment, the symptoms were not relieved, the high-sensitivity troponin I level continued to rise, the electrocardiogram results were abnormal, and chest computed tomography (CT) revealed multiple flaky and strip-shaped dense shadows in the heart.

INTERVENTION

The patient underwent removal of foreign bodies from the heart under cardiopulmonary bypass and tricuspid valvuloplasty, removal of intracardiac bone cement, and repair of the tricuspid valve and chordae.

OUTCOME

The patient recovered well postoperatively and was discharged from the hospital after 3 weeks. There were no intracardiac foreign bodies observed on chest CT after the operation.

LESSONS

For patients with cardiopulmonary discomfort after posterior decompression and bone cement-enhanced pedicle screw fixation, in view of the limitations of radiographic examination, we recommend performing chest CT examination to confirm the diagnosis. For patients with intravascular foreign body embolism, multidisciplinary team joint treatment saves lives.

A spear to the heart-the accidental discovery of a giant cement embolism in the right heart: a case report

BACKGROUND

The incidence of recognized cardiopulmonary cement embolism in the context of percutaneous vertebroplasty varies between 0% and 23%. In most cases, only small fragments embolize in the pulmonary arteries or the right heart cavities. The latter can cause potential harm by right ventricular perforation.

CASE SUMMARY

A 57-year-old patient was admitted to our department of cardiology due to exertional dyspnoea and chest pain. In the course of further diagnostic tests, a huge cement embolus was accidentally discovered in the right ventricle. The unusual size and length and the threat of ventricular perforation make this case so unique.

DISCUSSION

Large cement embolisms in kyphoplasty settings are possible and associated with the risk of fulminant complications.

Bedside echocardiography for diagnosis of intracardiac cement embolism after percutaneous vertebroplasty: A case report

This case report is to demonstrate that a female patient had suddenly become unconscious 14 hours after percutaneous vertebroplasty. Bedside echocardiogram showed that the patient had a strong echo in the right heart with a small amount of pericardial effusion. CT showed high density in the distal branches of both pulmonary arteries and a high density in the right heart. With the help of that, the doctor made the diagnosis of intracardiac cement embolism in a very short time. The bone cement in the heart was removed under emergency cardiopulmonary bypass, then the patient was discharged smoothly.
