“…Mechanical complications in PAH patients are usually related to progressive dilatation of the PA and include PA aneurysms, rupture and dissection and compression of different intrathoracic structures such as the left main coronary artery, pulmonary veins, main bronchi and the recurrent laryngeal nerves [279][280][281]. Symptoms and signs are not specific and are variable according to the different complications, including chest pain (angina-like or not), dyspnoea, regional lung oedema and sudden death.…”

Guidelines summarize and evaluate all available evidence on a particular issue at the time of the writing process, with the aim of assisting health professionals in selecting the best management strategies for an individual patient with a given condition, taking into account the impact on outcome, as well as the risk–benefit ratio of particular diagnostic or therapeutic means. Guidelines and recommendations should help health professionals to make decisions in their daily practice. However, the final decisions concerning an individual patient must be made by the responsible health professional(s) in consultation with the patient and caregiver as appropriate.

Pulmonary Artery Diameter Predicts Lung Injury After Balloon Pulmonary Angioplasty in Patients With Chronic Thromboembolic Pulmonary Hypertension

SummaryBalloon pulmonary angioplasty (BPA) has been an attractive strategy for chronic thromboembolic pulmonary hypertension (CTEPH), even though it occasionally causes lung injury. However, predictive factors of lung injury after BPA have not been established. Pulmonary artery (PA) dilatation is often observed in patients with pulmonary hypertension. We investigated the association between PA diameter and complications after BPA.The subjects were 19 CTEPH patients who underwent BPA. Patients were divided into two groups: patients with lung injury including asymptomatic lung infiltration on computed tomography (CT) images or mild hemoptysis (group L, n = 9) and no complications (group N, n = 10). PA diameter was measured on CT and corrected by the body surface area (PA diameter index).There were no significant differences in hemodynamic indices or the number of treated vessels between the two groups. Right, left, and main PA diameter indices were higher in group L than in group N. Among the clinical variables, the right, left, and main PA diameter indices were significant predictors for lung injury caused by BPA (right PA: OR 1.819, 95%CI 1.056-3.135, P < 0.05; left PA: OR 1.857, 95%CI 1.091-3.159, P < 0.05; main PA: OR 1.399, 95%CI 1.001-1.956, P < 0.05).The PA diameter index can be used to effectively predict the risk of lung injury after BPA.

“…The presence of significant parenchymal lung disease, which can distort the great vessel anatomy, also appears to affect the correlation between PH and pulmonary artery size [27]. The significant difference that was noticed in the measurements done in both normal patients and patients with CTEPH give the evaluation of the pulmonary artery and its branches an important approach; because the pulmonary artery size was associated with unexpected death [50].…”

Pulmonary hypertension (PH) is a complex disorder and may be related to a variety of diseases. It may arise in association with chronic thromboembolic pulmonary hypertension (CTEPH) or pulmonary embolism (PE). Knowledge of the radiological features is required to characterize and accurately diagnose the conditions and may improve the outcome. This study was designed to evaluate the clinical characteristics and the computerized tomography angiography findings in patients with PH, PE and CTEPH. Contrast-enhanced CT scans were acquired in 55 Sudanese patients with PE, 20 patients with PH, 25 patients with CTEPH and 50 normal subjects who were considered as control group. The CT diagnostic criteria for all cases were characterized. The clinical signs, parenchymal abnormalities, pulmonary tree and cardiac segments in all groups were characterized and compared with the control group. The results showed that the most common clinical characteristics were found to be chest pain, dyspnea, lower limb swelling, tachycardia and syncope which were correlated significantly with the presence of the disease. In all patients groups, the pulmonary vascular segments, cardiac segments and lung parenchyma changes were detected and were significantly different from the normal control subjects at p ≤ 0.01. It was found that CT angiography has a significant role in the diagnostic evaluation of these groups of patients. CT imaging is acceptably used in diagnosis, defining cause, quantifying heart segments and parenchyma changes in order to assess the feasibility of surgery, monitoring and therapeutic planning.
