Summary
Pulmonary thromboendarterectomy successfully treated severe dyspnea in an elderly patient with extensive pulmonary artery occlusion. This surgical intervention, even in older individuals, offers significant symptom improvement and a return to normal life.
Area of Science:
- Cardiology
- Thoracic Surgery
- Pulmonary Medicine
Background:
- Pulmonary hypertension significantly impacts elderly patients, often presenting with severe dyspnea unresponsive to conventional treatments like vasodilators and anticoagulants.
- Chronic thromboembolic pulmonary hypertension (CTEPH) can lead to near-complete occlusion of pulmonary artery branches, as seen in this case.
Observation:
- A 75-year-old female presented with severe dyspnea, elevated pulmonary vascular resistance (545 dynes·sec·cm⁻⁵), and extensive right pulmonary artery occlusion confirmed by imaging.
- The patient underwent pulmonary thromboendarterectomy (PTE) utilizing cardiopulmonary bypass, a videoscope for visualization, a flexible aspirator, and non-invasive monitoring for circulatory arrest.
Findings:
- The surgical procedure involved 101 minutes of cardiopulmonary bypass with a minimum temperature of 24.5°C.
- Post-operatively, the patient experienced marked improvement in symptoms and a return to her usual daily activities.
Implications:
- Pulmonary thromboendarterectomy is a viable and effective treatment option for elderly patients with severe CTEPH.
- Modifications to surgical techniques, including advanced visualization and monitoring, enhance the safety and efficacy of PTE in the geriatric population.
