pulmonary artery aneurysm

A 72-year-old male with a history of a triple-vessel coronary artery bypass graft years ago presented with a DeBakey type 2 aortic dissection and an aorto-left atrial fistula with patent bypass grafts (left internal mammary artery and saphenous vein grafts). He developed pulmonary oedema and required intubation. The right axillary artery was cannulated. After the ascending aorta and left internal mammary artery were clamped, the aorta was transected, leaving aortic tissue around two saphenous vein grafts as two separate patches...

Idiopathic pulmonary arterial hypertension is a serious condition that carries a poor prognosis. While exertional dyspnea is the most common symptom, angina like chest pain, most often due to right ventricle ischemia, may occur at advanced stages. We present a patient with pulmonary hypertension symptomatic for dyspnea and angina in whom computed coronary tomography angiography showed compression of the left main coronary artery by a large pulmonary artery aneurysm. Percutaneous coronary intervention and stenting was performed resulting in significant clinical improvement...

A pulmonary artery aneurysm (PAA) is a rare condition. It is treated in various ways, depending on its location and size. Herein, we describe the preoperative diagnosis of a PAA that was resected by segmentectomy. A 44-year-old female underwent CT, which revealed a 15-mm saccular protrusion in the right pulmonary artery and was diagnosed with PAA. The patient was initially observed without requiring further treatment, but a gradual increase in size led to therapeutic intervention. Because the PAA was located just peripheral to the right A8 bifurcation, embolization using interventional radiology was deemed too difficult...

Behcet's disease is a multisystemic vasculitis. It can affect the pulmonary artery in 2% to 5% cases. We discuss a case of a young male diagnosed with Behcet's disease on immunosuppressive therapy who presented with bilateral pulmonary artery aneurysms which were closed with covered stent and other devices.

A 62-year-old man was diagnosed an asymptomatic intralobar pulmonary sequestration (IPS) supplied by a short-neck proximal 57x25mm aneurysmal artery originating from the mid-descending aorta. The patient underwent thoracic endovascular aneurysm repair (TEVAR), an aortic endograft was released to entirely restore the aberrant vessel. The pulmonary resection was performed. A triportal video-assisted thoracic surgery (VATS) left lower lobectomy was carried out. TEVAR minimized the risk of bleeding and allowed a safe pulmonary resection with a minimally invasive approach...

AIM: To investigate the causal relationship between metabolic syndrome (MetS) and its components and 14 cardiovascular diseases using Mendelian randomization (MR). METHODS: We used summary statistics from large-scale genome-wide association studies of MetS, its components, and cardiovascular diseases. We performed a two-sample MR analysis using the inverse-variance weighted method and other sensitivity methods. We also performed multivariate MR to adjust for potential risk factors...

Endovascular treatment of complex vascular anomalies shifts the risk of open surgical procedures to the benefit of minimally invasive endovascular procedural solutions. Complex open surgical procedures used to be the only option for the treatment of a myriad of conditions like pulmonary and aortic valve replacement as well as cerebral aneurysm repair. However, due to advancements in catheter-delivered devices and operator expertise, these procedures (along with many others) can now be performed through minimally invasive procedures delivered through a central or peripheral vein or artery...

A 26-year-old male with Behçet's disease (BD) presented with recurrent oral and genital ulcers, bilateral pneumonia, and a left lower pulmonary artery aneurysm. Endovascular coil embolization was initially performed, followed by treatment with prednisone, colchicine, and azathioprine. Despite treatment, disease progression occurred, requiring additional embolization, intravenous pulse methylprednisolone, and cyclophosphamide. Ultimately, a combination of medical and endovascular interventions resolved the pulmonary arterial aneurysms...

We present a case of a complex congenital coronary artery fistula between the right coronary artery, left anterior descending artery, and the main pulmonary artery complicated by massive aneurysms and a left-to-right shunt. We highlight the multimodality approach to assessment and the importance of individualized management of complex coronary fistulas.

<b/> Background: In the latest American Heart Association guidelines, influenza vaccination is recommended for patients with peripheral arterial disease (PAD). The vaccination coverage in this specific population is currently unknown. This study aims to determine the adherence to influenza vaccination in a PAD population and identify associated determinants. Patients and methods. Hospitalized patients and outpatients with PAD from two university departments of vascular medicine were prospectively included...

MicroRNAs (miRs, miRNAs) are known to have a part in various human illnesses, such as those related to the heart. One particular miRNA, miR-155, has been extensively studied and has been found to be involved in hematopoietic lineage differentiation, immunity, viral infections, inflammation, as well as vascular remodeling. These processes have all been connected to cardiovascular diseases, including heart failure, diabetic heart disease, coronary artery disease, and abdominal aortic aneurysm. The impacts of miR-155 depend on the type of cell it is acting on and the specific target genes involved, resulting in different mechanisms of disease...

BACKGROUND: Thoracoabdominal aortic aneurysms (TAAAs) are rare but complicated aortic pathologies that can result in high morbidity and mortality. The whole-aorta hemodynamic characteristics of TAAA survivors remains unknown. This study sought to obtain a comprehensive view of flow hemodynamics of the whole aorta in patients with TAAA using four-dimensional flow (4D flow) magnetic resonance imaging (MRI). METHODS: This study included patients who had experienced TAAA or abdominal aortic aneurysm (AAA) and age- and sex-matched volunteers who had attended China Hospital from December 2021 to December 2022 in West...

Pulmonary Artery Aneur ysm (PAA), whether congenital or acquired, is a rare diagnostic find ing com pare d to aor tic aneur ysms. There have been fe w cases where PA As were documented as a complication of untreated Patent Ductus Ar teriosus (PDA) due to long-standing Pulmonary Arterial H ypertension (PAH). However, it is quite rare for a case of PAA to be reported with co-existing PDA without PAH. This report highlights a case of a five -year-old girl who was presented with palpitations, easy fatigability, fever, c yanos is, and vomiting...

Pulmonary artery pseudoaneurysms (PAPs) are uncommon, yet they frequently result in hemoptysis and are associated with a poor prognosis. We report a case of an 87-year-old male patient. Initially, he was admitted to a previous hospital, and diagnosed with a lung abscess in the left lower lobe. On the second hospital day, he developed hemoptysis. A contrast-enhanced chest computed tomography (CT) identified an infectious pulmonary artery pseudoaneurysm. On the ninth hospital day, pulmonary artery coil embolization was successfully performed, significantly improving the patient's condition...

Giant septic pulmonary artery aneurysms (PAAs) are rare but important entities, with few cases having been reported worldwide. Early diagnosis and prompt treatment are crucial in the management of such cases. We report a 56-year-old female patient presenting with fatigue, nausea and vomiting who was first diagnosed with diabetic ketoacidosis (DKA) and developed life-threatening giant infectious PAA secondary to SARS-CoV-2 infection and Actinomyces odontolyticus sepsis. The patient did not develop any specific symptoms, and enhanced computed tomography (CT) revealed a massive PAA of 5...

BACKGROUND: A coronary artery aneurysm is a dilation exceeding 1.5 times the diameter of the patient's largest coronary vessel. They are rare, varying in prevalence between 1.4 and 4.9%. Additionally, they carry a high risk of potential complications, including thrombosis and myocardial infarction, with a risk of rupture. We present an interesting case of a patient with initial imaging suggesting a mass in the right ventricle. CASE SUMMARY: This patient initially presented with acute hypoxic respiratory failure related to pulmonary oedema...

BACKGROUND: Enterprise stent was approved for the treatment of wide-necked intracranial aneurysms. However, it has been widely used in the endovascular treatment of intracranial artery stenosis, which is still controversial. The purpose of this study was to evaluate the safety and efficiency of the Enterprise stent in the endovascular treatment of intracranial artery stenosis disease. METHODS: We conducted a retrospective case series of 107 patients with intracranial artery stenosis who received Enterprise stent implantation at Nanjing Drum Tower Hospital from January 2020 to December 2022...
