Bullet embolism to the peripheral arterial system is a rare phenomenon which frequently results in misdiagnosis due to lack of early symptoms. Embolisms can go to either arterial or venous systems with common sites of injury including the left ventricle, pulmonary vein, thoracic and abdominal aorta and peripheral arteries. Herein we present a case of a 19 year old patient with multiple gunshot wounds to the torso with a bullet embolism to the left popliteal artery necessitating embolectomy. This subsequently led to diagnosis and repair of an abdominal aortic psuedoaneurysm not clearly evident on initial imaging...

PURPOSE: Pulmonary hypertension and exercise-induced oxygen desaturation (EID) influence acute exacerbation of COPD. Computed tomography (CT)-detected pulmonary artery (PA) enlargement is independently associated with acute COPD exacerbations. Associations between PA to aorta (PA:A) ratio and EID in patients with COPD have not been reported. We hypothesized that the PA:A ratio correlated with EID and that results of the 6-minute walk test (6MWT) would be useful for predicting the risk associated with PA:A >1...

Air embolism is often an iatrogenic complication which may occur in venous or arterial circulation depending on the port of entry. We present two cases in which air embolism occurred in venous and arterial circulation after contrast medium injection (CMI) and coronary artery bypass graft (CABG) surgery, respectively. In one case, accumulation of air bubbles was observed in the pulmonary artery after CMI. This was attributed to inadvertent injection of air owing to improper connection of the injector and the catheter...

BACKGROUND: Previously we found that smooth muscle cell (SMC)-specific knockout of miR-17~92 attenuates hypoxia-induced pulmonary hypertension. However, the mechanism underlying miR-17~92-mediated pulmonary artery SMC (PASMC) proliferation remains unclear. We sought to investigate whether miR-17~92 regulates hypoxia-inducible factor (HIF) activity and PASMC proliferation via prolyl hydroxylases (PHDs). METHODS AND RESULTS: We show that hypoxic sm-17~92(-/-) mice have decreased hematocrit, red blood cell counts, and hemoglobin contents...

Selexipag (NS-304; [2-{4-[(5,6-diphenylpyrazin-2-yl)(isopropyl)amino]butoxy}-N- (methylsulfonyl)acetamide]) is a novel, orally available non-prostanoid prostacyclin receptor (IP receptor) agonist that has recently been approved for the treatment of pulmonary arterial hypertension (PAH). We examined the effect of the active metabolite of selexipag, MRE-269, and IP receptor agonists that are currently available as PAH therapeutic drugs on the relaxation of rat, porcine and human pulmonary artery. cAMP formation in human pulmonary artery smooth muscle cells was induced by all test compounds (MRE-269, epoprostenol, iloprost, treprostinil and beraprost sodium) and suppressed by IP receptor antagonists (CAY10441 and 2-[4-(1H-indol-4-yloxymethyl)-benzyloxycarbonylamino]-3-phenyl-propionic acid)...

The pulmonary artery catheter (PAC) is the most common method of measuring cardiac output in cardiac surgery. However, its use has always been questioned in terms of survival benefit, specifically with regard to the accuracy of its measurements and its invasive nature, with the potential for serious complications. In this review we aimed to develop a clear understanding of the pitfalls of the use of PAC, and discuss its risks and available alternatives. We conclude that there is no indication for the routine use of PAC such that clinicians should carefully consider the clinical risks and benefits on a patient by patient basis...

BACKGROUND: Pulmonary arterial hypertension (PAH) is a rare and fatal disease. The prostacyclin (PGI2) pathway is a well-known therapeutic target for PAH. As a novel vasoconstrictive peptide, coupling factor 6 (CF6) has been recognized as the only endogenous inhibitor of PGI2. However, the relationship between CF6 and PAH is still unknown. In this study, we investigated the involvement of CF6 in PAH in rats. METHODS: A total of 80 Sprague-Dawley rats were randomly divided into 2 groups: a control group (with saline intraperitoneally) and a monocrotaline (MCT)-treated group (with MCT 60mg/kg intraperitoneal injection)...
