Patient: Female, 71-year-old
Final Diagnosis: Pacemaker related pleural effusion
Symptoms: Dry cough
Medication:—
Clinical Procedure: —
Specialty: Cardiology • General and Internal Medicine
Objective:
Unusual or unexpected effect of treatment
Background:
Post-cardiac injury syndrome, including pleural effusion as a delayed complication of permanent pacemaker implantation, has rarely been reported. To resolve pleural effusion, prolonged chest tube placement is often required. Anti-inflammatory agents combined with diuretics are also often prescribed. Saireito, a Japanese herbal medication, which is a combination of Goreisan and Shousaikoto, has both anti-inflammatory and water-modulation properties and has been used for edema (lymph edema, cerebral edema) and inflammation (chronic nephritis).
Case Report:
We describe a 71-year-old woman with a history of syncope and bradycardia who underwent dual permanent pacemaker implantation (placed in the right chest because of a persistent left superior vena cava) without complications. Two months later, she came to the hospital as an outpatient with a dry cough, and was diagnosed with right-sided pleural effusion. A pleural fluid analysis revealed exudative effusion, according to Light’s criteria. The fluid was negative for infectious etiology. Chest X-ray, computed tomography, and echocardiography revealed no signs of pericardial effusion or perforation of the pacemaker lead to outside the heart. The pleural effusion persisted despite use of anti-inflammatory medication for several weeks and diuretics for a short period. Saireito was administered with good response; the pleural effusion resolved completely and there was no deterioration of renal function.
Conclusions:
The present case highlights the clinical significance of Saireito as an effective therapeutic agent for late-onset pacemaker-related pleural effusion, without adverse effects such as renal dysfunction.
