Chronic thromboembolic pulmonary hypertension (CTEPH) is a sequela of a pulmonary embolus that occurs in approximately 1%-3% of patients. Pulmonary thromboendoarterectomy (PTE) can be a curative procedure, but balloon pulmonary angioplasty (BPA) has emerged as an option for poor surgical candidates. We used the National Inpatient Sample to query patients who underwent PTE or BPA between 2012 and 2019 with CTEPH.

Purpose: Pulmonary artery sarcomas (PAS) are rare malignant tumours that originate from the intimal layer of the pulmonary artery, occur in middle age and have a poor prognosis. In planning appropriate treatment, malignant disease should be suspected whenever there are specific clinical and radiological manifestations, in order to establish the differential diagnosis with acute pulmonary embolism or chronic thromboembolic pulmonary hypertension, with which this malignancy is most commonly confused.

Materials And Methods: Between 2008 and 2012, we managed four adult patients with a nonspecific clinical presentation who, at the conclusion of the diagnostic process, were found to be affected by PAS.

Delayed femoral pseudoaneurysm formation after percutaneous coronary intervention.

Clin Imaging

June 2007

Second Department of Surgery, Faculty of Medicine, University of Yamanashi, 1110 Shimokato, Chuo City, Yamanashi 409-3898, Japan.

Five femoral pseudoaneurysms were treated among 573 patients who underwent percutaneous coronary interventions. Four of the five patients suffered from diabetes mellitus and four patients needed regular hemodialysis due to chronic renal failure. One patient's course was complicated by infection.

Plaque composition in plexogenic and thromboembolic pulmonary hypertension: the critical role of thrombotic material in pultaceous core formation.

Heart

August 2002

Transplant Research Area, Molecular Diagnostic Cardiovascular and Transplant Pathology Laboratory, IRCCS Policlinico S Matteo, Pavia, Italy.

Background: Patients with pulmonary hypertension develop intimal plaques in large pulmonary arteries.

Objective: To test the hypothesis that the composition of such plaques differs depending on whether the aetiology of the disease is thromboembolic or hypertensive.

Design: Chronic thromboembolic and plexogenic pulmonary hypertension (primary and secondary (Eisenmenger syndrome)) were investigated.

Nitric oxide improves hypoxaemia following reperfusion oedema after pulmonary thromboendarterectomy.

Br J Anaesth

December 1995

Department of Cardiothoracic Anaesthetics and Intensive Care, Karolinska Hospital, Stockholm, Sweden.

A patient underwent pulmonary thromboendoarterectomy for chronic, major-vessel thromboembolic pulmonary hypertension. After operation the patient developed reperfusion oedema and hypoxaemia which was treated successfully with inhalation of nitric oxide. Before operation, the response to inhaled nitric oxide was characterized by a slight reduction in pulmonary vascular resistance but without improvement in gas exchange.
