Needle fragment embolism into the right ventricle: a rare cause of chest pain case report and literature review

Postmortem Imaging of an Unusual Case of Fatal Heart and Lung Perforation Due to Self-Treatment

Intentional or accidental cardiothoracic injuries caused by needles and pins are rare and commonly reported in individuals with psychiatric conditions or intravenous drug users. Although rare, these cases could result in serious injury during the performance of an autopsy and highlight the importance of post-mortem radiology. Therapeutic complications with cardiac perforation have been reported due to pericardiocentesis and acupuncture. The majority of reported cases were not fatal and some had a prolonged asymptomatic period of weeks or even years after insertion. Needles or other sharp objects can reach the cardiovascular system directly through the chest wall, indirectly from any segment of the gastrointestinal tract after swallowing needles, or through migration of broken needles from distant injection sites in intravenous drug users. We report a case of rapidly fatal cardiopulmonary injuries following "self-treatment" to "pop" a cyst with a piercing needle. The scene, autopsy, computed tomography, and digital x-ray findings of this unique case are discussed with a review of selective literature. In this case, the right lung and heart showed multiple perforations, possibly resulting from heartbeats or respirations pushing the organs against the needle. To our knowledge, perforations in this setting of "self-treatment" have not been previously reported in the literature.

Mitral valve regurgitation and endocarditis triggered by a needle

BACKGROUND

Cardiac foreign bodies are extremely rare in clinical patients, especially when foreign bodies damage the internal structure of the heart coincidentally after they penetrate the heart.

CASE PRESENTATION

Here, we report the case of a two-year-old girl whose heart was penetrated by a needle, which triggered mitral valve regurgitation and endocarditis. After a comprehensive inspection, accurate judgment and surgical preparation, we removed the needle and repaired her mitral valve. Fortunately, she recovered postoperatively.

CONCLUSION

From this case, we can know that when cardiac foreign bodies are suspected, ultrasound is an important inspection method. Moreover, the approaches for handling each such case are different depending on the associated injuries.

Needle Embolism to the Heart: A Case Report and Review

Needle embolisms in the heart are quite rare, and their management is largely based on clinical experience. We describe a patient with chest pain and shortness of breath, whose electrocardiogram revealed subtle inferolateral ST segment elevations. The patient was found to have a bloody pericardial effusion causing tamponade from a long-ago injected needle. Removal of a needle is a complicated decision, that should be done in a multi-disciplinary fashion to minimize complications. Removal may not always be necessary if the needle is in a stable position and not in danger of migration.

A case of needle embolism in a drug abuser, a diagnostic and therapeutic challenge

Background

Needle embolism is a rare complication of intravenous habit. Clinical manifestations include recurrent pericarditis, tamponade, cardiac perforation, and infective endocarditis. We describe the case of needle embolization in a young intravenous opiate abuser.

Case presentation

We describe a rare complication of intravenous misuse in a 23-year-old patient. He presented at the emergency department with chest pain and shortness of breath. He complained of remittent fever ensued 6 months before. Echocardiographic and radiologic images revealed pericardial effusion and a needle fragment inside the pericardium. The needle was removed through left-anterior mini-thoracotomy, after CT-guided carbon tracking.

Conclusions

The presence of a foreign body within the heart resulted from the migration of a needle fragment from a peripheral vessel. It caused fever and recurrent pericarditis. In similar cases, surgical extraction is the therapy of choice.

Occult Ingested Foreign Body: An Unusual Cause of Perimyocarditis

BACKGROUND

Intracardiac foreign bodies have been described in the literature, however, they are rare entities, particularly in pediatric patients. We present a case of a teenage boy diagnosed with perimyocarditis who was found to have an unexpected underlying etiology: an unknowingly swallowed sewing pin.

CASE REPORT

A 17-year-old boy presented to the Emergency Department with 3 days of chest pain suggestive of perimyocarditis, in the absence of prodromal symptoms or trauma. Electrocardiogram at the time of presentation demonstrated diffuse ST-segment elevation consistent with perimyocarditis. A chest radiograph was significant for a linear density in the anterior mid chest, concerning for foreign body. Chest computed tomography confirmed the presence of a 3.5-cm linear metallic foreign body within the right ventricle. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case demonstrates the need to consider alternative etiologies for perimyocarditis, especially in the absence of the typical prodromal symptoms. In addition, it highlights the potential devastating complications of foreign body ingestion and challenges the paradigm that ingested sharp linear foreign bodies < 5 cm in length rarely cause problems.

Radiological features and management of retained needles

The identification of retained needles is essential because of their sharp structure with possible life-threatening complications. However, radiological evaluation could be challenging, especially in case of needles' relatively poor conspicuity and small dimension. This pictorial essay focuses on clinical issues (needle features, retention mechanisms and associated complications) and technical aspects (choice of the best diagnostic modality and technique) that can lead the radiologist to an earlier and proper diagnosis of needle retention in order to provide the best treatment for the patient.

Needle Embolization: Suspecting Needle Migration in Intravenous Drug Abusers

BACKGROUND

Thirteen million people inject drugs globally, making intravenous drug abuse a substantial concern worldwide. While intravenous drug users occasionally report the breaking of a needle into the skin or subcutaneous tissue, central needle migration remains a rare but potentially devastating complication.

CASE REPORT

A 27-year-old man with a history of intravenous drug abuse presented to the emergency department with the sudden onset of left-sided neck pain, chills, and subjective fever with a history of needle breaking in his left neck 3 weeks earlier while using heroin. A computed tomography scan of his chest revealed a needle lodged in the right ventricle with associated mediastinitis and mass effect on the left brachiocephalic vein, and a left internal jugular thrombus. Broad-spectrum antibiotics were initiated. This patient was managed nonsurgically for several reasons and was discharged on hospital day 12 with oral antibiotics. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Intravenous drug abusers commonly use cervical veins when their peripheral vasculature has become sclerosed. This puts intravenous drug users at increased risk for intravascular embolization. Due to varied symptomology-chest pain, dyspnea, fever, or asymptomatic-and timelines-days, weeks, or months-after reported needle fragmentation, this remains a complex and likely underdiagnosed condition. Case reports describe serious complications of intracardiac needle embolization, such as cardiac perforation, constrictive pericarditis, septic endocarditis, dysrhythmias, granulomas, venous thrombosis, empyema, acute or delayed spontaneous pneumothorax, osteomyelitis, and valvular damage. In this complicated patient population, clinicians should consider needle retention and relocation in patients who report needle breaking or in those who present with chest pain, dyspnea, or fever among other complaints.
