Pulmonary Arterial Hypertension in a Patient With a Lung Mass: Any Link?
Cureus
December 2024
Pulmonology, King Abdulaziz Medical City, Jeddah, SAU.
A 52-year-old female patient with a history of atrial septal defect repair presented with progressive dyspnea and echocardiographic findings suggestive of pulmonary hypertension (PH). Incidentally, a lung mass was discovered on computed tomography (CT). Initial evaluation revealed World Health Organization functional class III symptoms and significant weight loss.

From the Department of Anesthesiology, Perioperative and Pain Medicine, Brigham and Women's Hospital, Boston, Massachusetts.
Background: Hypoxemia occurs with relative frequency during one-lung ventilation (OLV) despite advances in airway management. Lung perfusion scans are thought to be one of the most accurate methods to predict hypoxemia during OLV, but their complexity and costs are well-known limitations. There is a lack of preoperative stratification models to estimate the risk of intraoperative hypoxemia among patients undergoing thoracic surgery.

Article Synopsis
- Two patients with paroxysmal atrial fibrillation developed pulmonary vein stenosis (PVS) after AF ablation, with Case 1 being a female in her 50s and Case 2 a male in his 60s.
- The first patient showed high-degree left superior PVS 15 months post-ablation, while the second had progressive PVS nine months later, confirmed through contrast-enhanced CT and ventilation-perfusion scans.
- PVS is a rare complication of AF ablation that can lead to severe issues if untreated, and the case report emphasizes the importance of V/Q scans in assessing PVS despite its common association with pulmonary embolism evaluations.
How necessary it is to perform a ventilation scan in patients with a history of COVID-19 to rule out pulmonary thromboembolism?

Nuclear Medicine Research Center, Mashhad University of Medical Sciences, Mashhad, Iran.
Objectives: This study evaluated the necessity of a ventilation scan in patients suspected of PE with a history of COVID-19 infection.
Methods: This was a cross-sectional study of patients with PCR-confirmed COVID-19 and suspected PE at a tertiary care hospital in 2020. They underwent ventilation/perfusion (V/Q) scintigraphy using single-photon emission computed tomography/computed tomography (SPECT/CT) and CT scans with or without contrast.
Development and validation of a Prediction Model for Chronic Thromboembolic Pulmonary Disease.
Respir Res
December 2024
Department of Respiratory and Critical Care Medicine, Shandong Provincial Hospital Affiliated to Shandong First Medical University, 9677 Jing Shi Road, Jinan, 250000, Shandong, China.
Background: Acute pulmonary embolism (APE) is a critical disease with a high mortality rate, some of the surviving patients may develop chronic thromboembolic pulmonary disease (CTEPD), which affects the patient's prognosis. However, the research on the early diagnosis of CTEPD is limited. This study aimed to establish a prediction model for earlier identification of CTEPD.
