Pulmonary arteriovenous malformations (PAVMs) are atypical vascular structures involving a direct connection between the pulmonary arterial and venous circulations. While PAVMs are a relatively uncommon disorder, unmanaged cases are at risk for the development of serious complications including embolization and infection. Since their first description in 1897, PAVMs have been identified and treated in a variety of ways. Advancements in diagnostic methods and operative techniques have allowed for more effective treatment of the disease...

Pulmonary arteriovenous malformations (PAVMs) are structurally abnormal vascular communications that provide a continuous right-to-left shunt between pulmonary arteries and veins. Their importance stems from the risks they pose (>1 in 4 patients will have a paradoxical embolic stroke, abscess or myocardial infarction while life-threatening haemorrhage affects 1 in 100 women in pregnancy), opportunities for risk prevention, surprisingly high prevalence and under-appreciation, thus representing a challenging condition for practising healthcare professionals...

INTRODUCTION: While the optimal care of patients with massive pulmonary embolism (PE) is unclear, the general goal of therapy is to rapidly correct the physiologic derangements propagated by obstructive clot. Extracorporeal membrane oxygenation (ECMO) in this setting is promising, however the paucity of data limits its routine use. Our institution expanded the role of ECMO as an advanced therapy option in the initial management of massive PE. The purpose of this project was to evaluate ECMO-treated patients with massive PE at an academic medical center and report shortterm mortality outcomes...

INTRODUCTION: Intermediate-high risk pulmonary embolism (IHR-PE) has a poor prognosis, but is under-represented in trials of direct oral anticoagulants (DOACs) in venous thromboembolic disease (VTE). We aimed to assess whether the administration of DOACs was equivalent to the conventional (CONV) treatment of low-molecular weight heparin bridged with warfarin for treating IHR-PE. METHODS: We conducted a retrospective cohort study including 59 consecutive patients admitted with IHR-PE and followed for up to three months after discharge...

In this report, we describe a male patient who presented with recurrent life-threatening hemoptysis due to the sequential formation of multiple pulmonary aneurysms. Both pulmonary artery coil embolization and right lower lobectomy were performed, with limited success. The patient experienced extensive bilateral femoral DVT extending into the inferior vena cava, with massive hemoptysis, fulfilling the diagnosis of Hughes-Stovin syndrome. A final diagnosis of Behçet disease was made following extensive investigation, and the patient responded well to prednisone 20 mg orally and azathioprine 100 mg orally...

Rasmussen's aneurysm, a very rare complication of active pulmonary tuberculosis (TB), is a pulmonary artery aneurysm adjacent to or within a tuberculous cavity. It may lead to rupture and life threatening massive hemoptysis, an uncommon but challenging medico-surgical emergency. This complication warrants attention in view of the resurgence of tuberculosis and increasing occurrence of multi-drug resistant TB, especially in resource-poor, high-TB burden countries like India. We present a case of an elderly man who presented to the emergency room with low-grade fever, cough and hemoptysis...

Emergency bedside veno-arterious ECMO implantation can be the only saving gesture in the suspicion of acute massive pulmonary embolism leading to haemodynamic failure, even before CT-scan imaging. Once the massive pulmonary embolism is confirmed it is possible to undergo surgical or percutaneous pulmonary thrombectomy, when thrombolytic therapy is contraindicated.

Pregnancy is an acquired hypercoagulable state. Most patients with thrombosis that develops during pregnancy present with deep vein leg thrombosis and/or pulmonary embolism, whereas the development of mesenteric vein thrombosis (MVT) in pregnant patients is rare. We report a case of MVT in a 34-year-old woman who had achieved pregnancy via in vitro fertilization-embryo transfer (IVF-ET). At 7 wk of gestation, the patient was referred to us due to abdominal pain accompanied by vomiting and hematochezia, and she was diagnosed with superior MVT...

The objective of this study was to evaluate the heritability of neonatal arterial ischemic stroke (NAIS) in relation to family history of thromboembolic event, maternal diseases, and thrombophilia in both parents ( F5G1691A, F2G20210A, and MTHFRC677 T mutations). Forty-two consecutive infants ≥36 weeks of gestation <28 days of life with acute symptomatic NAIS and their parents, as well as 129 controls, were prospectively recruited. Information on maternal data (age, body mass index, oral contraception, migraine, epilepsy, hypertension, and immune disease) and a 3-generation pedigree regarding myocardial infarction, pulmonary embolism, cerebrovascular event, and deep vein thrombosis were obtained...

BACKGROUND: Postoperative myocardial injury (PMI) is a strong predictor of mortality after noncardiac surgery. PMI is believed to be attributable to coronary artery disease (CAD), yet its etiology is largely unclear. We aimed to quantify the prevalence of significant CAD in patients with and without PMI using coronary computed tomography angiography (CCTA). METHODS: This prospective cohort study included patients of 60 years or older without a history of cardiac disease and with and without PMI after intermediate- to high-risk noncardiac surgery...

The development of new anticoagulants is an important goal for the improvement of thrombosis treatment. Recent studies have suggested the importance of thrombin inhibitors in the modulation of thromboembolic disorders. The aim of this study was to discover a new small-molecule thrombin inhibitor. In this study, the compound JJ1, which has a novel scaffold, was selected by structure-based docking simulation to determine its potential inhibitory activity against thrombin. JJ1 was shown to inhibit the catalytic activity of human α-thrombin with a K i of 0...

Development of aspergilloma is common in cases with a fungus ball-like shadow in cavities due to old tuberculosis. Some reports have shown that blood clots tend to appear as a fungus ball-like shadow. A 71-year-old man with a history of pulmonary tuberculosis presented with a fungus ball-like shadow in an old cavity and hemoptysis. There was no evidence of aspergillus infection on various examinations. We confirmed a blood clot and aneurysm of an artery under direct vision by bronchoscopy. A lateral thoracic artery aneurysm was detected by angiography...

BACKGROUND: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is increasingly adopted for the treatment of cardiogenic shock (CS). However, a marker of successful weaning remains largely unknown. Our hypothesis was that successful weaning is associated with sustained microcirculatory function during ECMO flow reduction. Therefore, we sought to test the usefulness of microcirculatory imaging in the same sublingual spot, using incident dark field (IDF) imaging in assessing successful weaning from VA-ECMO and compare IDF imaging with echocardiographic parameters...

Intermediate risk pulmonary embolism is common and carries a risk of progression to hemodynamic collapse and death. Catheter directed thrombolysis is an increasingly utilized treatment option, based largely on the assumptions that it is more efficacious than anticoagulation alone, and safer than systemic thrombolysis. In this review, we critically analyze the published data regarding catheter directed thrombolysis for the treatment of intermediate risk pulmonary embolism. Catheter directed thrombolysis reduces right heart strain and lowers pulmonary artery pressures more quickly than anticoagulation alone...
