Pulmonary endarteritis and endocarditis complicated with septic embolism: a case report and review of the literature.

BACKGROUND: Pulmonary endarteritis is a rare clinical phenomenon with congenital heart that can potentially lead to major complications. CASE PRESENTATION: We report a 47-year-old man with pulmonary endarteritis. This patient presented with hypertension, chest pain and a previous history of pulmonary valve disease during childhood. Also, eight-months prior, he was hospitalized with dyspnea (Functional Class III), cough, phlegm, and night sweats without fever. Echocardiographic diagnosis in the first transtransthoracic echocardiography (TTE) was intense pulmonary valve stenosis (PVS) an, thus, the pulmonary valve vegetation and PVS, established by transesophageal echocardiography (TEE). He was referred for surgery after 1 weeks of intravenous antibiotic therapy for removal of the vegetation. CONCLUSIONS: Finally he was asymptomatic at 3-months of follow-up and was clinically in good condition. Therefore, the detection of infective endocarditis of the lung valve must not lengthy be prolonged.

A case report on endarteritis in a child with coarctation of aorta.

Coarctation of aorta(CoA), complicated by endarteritis in a children is very rare. Here we present a case of endarteritis in an unoperated CoA in a four year old boy. CoA had been diagnosed in the referring hospital, yet the diagnosis of endocarditis distal to CoA, was made in the tertiary center using modified transthoracic echo windows or focused views. After six weeks of intravenous antibiotic treatment, a coarctectomy and end-to-end anastomosis was performed and he recovered clinically well. This case report concludes that echocardiography remains as the standard diagnostic method for identifying intracardiac manifestations of infective endocarditis/endarteritis. Last but foremost, it delineates the importance of modified transthoracic echo windows or focused views in identifying the unusual position of endocarditis.

Fungal prosthetic aortic valve endocarditis and endarteritis: An unusual cause of aortic root vegetations.

Fungal endocarditis is a relatively rare occurrence with high morbidity and mortality. Patients may have an indolent and non-specific course requiring a high index of suspicion to make a diagnosis. Here, we present the case of a 33-year-old patient who presented with fevers and acute lower limb ischemia requiring a 4-compartment fasciotomy caused by septic emboli from Candida albicans endocarditis. The patient had a large vegetation in the ascending aorta associated with a mycotic aneurysm, which is an exceedingly rare location for a vegetation. We also review the literature and summarize the typical echocardiographic appearance and vegetation locations in fungal endocarditis.

[POSSIBILITIES OF THE FORCED INTRAARTERIAL INJECTION OF MEDICINAL PREPARATIONS IN A COMPLEX OF TREATMENT FOR THE LOWER EXTREMITIES CHRONIC ISCHEMIA].

The efficacy and prognostic significance of the forced intraarterial injection of medicinal preparations in complex of treatment in patients, suffering chronic ischemia of the lower extremities tissues, was studied. In experimental conditions of the main blood flow blockade the forced intraarterial injection of medicinal preparations have promoted the release of vessels from cellular aggregates and the blood clots; and in the ischemia of degree ІІ - ІІІа ­ has determined more pronounced clinical improvement. Appearance of reactive hyperemia of the foot in terms more than 2 min have witnessed the hopelessness of the extremity saving.

Isolated endarteritis and kidney transplant survival: a multicenter collaborative study.

Isolated endarteritis of kidney transplants is increasingly recognized. Notably, microarray studies revealed absence of immunologic signatures of rejection in most isolated endarteritis biopsy samples. We investigated if isolated endarteritis responds to rejection treatment and affects kidney transplant survival. We retrospectively enrolled recipients of kidney transplant who underwent biopsies between 1999 and 2011 at seven American and Canadian centers. Exclusion criteria were recipients were blood group-incompatible or crossmatch-positive or had C4d-positive biopsy samples. After biopsy confirmation, patients were divided into three groups: isolated endarteritis (n=103), positive controls (type I acute T cell-mediated rejection with endarteritis; n=101), and negative controls (no diagnostic rejection; n=103). Primary end points were improved kidney function after rejection treatment and transplant failure. Mean decrease in serum creatinine from biopsy to 1 month after rejection treatment was 132.6 µmol/L (95% confidence interval [95% CI], 78.7 to 186.5) in patients with isolated endarteritis, 96.4 µmol/L (95% CI, 48.6 to 143.2) in positive controls (P=0.32), and 18.6 µmol/L (95% CI, 1.8 to 35.4) in untreated negative controls (P<0.001). Functional improvement after rejection treatment occurred in 80% of patients with isolated endarteritis and 81% of positive controls (P=0.72). Over the median 3.2-year follow-up period, kidney transplant survival rates were 79% in patients with isolated endarteritis, 79% in positive controls, and 91% in negative controls (P=0.01). In multivariate analysis, isolated endarteritis was associated with an adjusted 3.51-fold (95% CI, 1.16 to 10.67; P=0.03) risk for transplant failure. These data indicate that isolated endarteritis is an independent risk factor for kidney transplant failure.

Brucella arteritis: clinical manifestations, treatment, and prognosis.

Brucellosis is the most common bacterial zoonosis, and causes a considerable burden of disease in endemic countries. Cardiovascular involvement is the main cause of mortality due to infection with Brucella spp, and most commonly manifests as endocarditis, peripheral and cerebrovascular aneurysms, or arterial and venous thromboses. We report a case of brucellosis presenting as bacteraemia and aortic endarteritis 18 years after the last known exposure to risk factors for brucella infection. The patient was treated with doxycycline, rifampicin, and gentamicin, and underwent surgical repair of a penetrating aortic ulcer, with a good clinical recovery. We review the signs and symptoms, diagnostic approach, prognosis, and treatment of brucella arteritis. We draw attention to the absence of consensus about the optimum therapy for vascular brucellosis, and the urgent need for additional studies and renewed scientific interest in this major pathogen.

Carotid inflammation is unaltered by exercise in hypercholesterolemic Swine.

INTRODUCTION: Reduction of vascular inflammation might contribute to the beneficial effects of exercise. We hypothesized that 1) exercise would reduce carotid endothelial vascular cell adhesion molecule-1 (VCAM-1) and that 2) in vivo detection of carotid inflammation can be achieved in a large animal model using contrast-enhanced ultrasound (CEU) with VCAM-1-targeted microbubbles (MBs). METHODS: Familial hypercholesterolemic (FH) swine were divided into sedentary (Sed) and exercise-trained (Ex) groups. Ex pigs underwent 16-20 wk of treadmill aerobic exercise. At the end of the study, in vivo CEU with VCAM-1-targeted MBs and assessment of endothelial-dependent dilation (EDD) were performed in carotid arteries. VCAM-1 mRNA and protein expression were compared with markers of atherosclerotic disease and health, and in vitro EDD was assessed in carotid arteries. RESULTS: Exercise training neither reduced inflammation nor improved EDD in carotid arteries of FH swine. Markers of atherosclerosis including VCAM-1 were prominent in the bifurcation compared with the proximal or distal common carotid artery and inversely associated with phosphorylated and total endothelial nitric oxide synthase. Signal intensity from VCAM-1-to-control MBs positively correlated with carotid VCAM-1 protein expression, validating our technique. CONCLUSION: These results first demonstrate that aerobic exercise has no effect on carotid endothelial inflammatory markers and EDD in FH swine. Second, our findings indicate that CEU using VCAM-1-targeted MBs can detect inflammation in vivo, providing strong foundations for longitudinal studies examining the effect of therapeutic interventions on the inflammatory status of the endothelium.

Femoral artery infections associated with percutaneous arterial closure devices.

Hemostasis obtained by manual compression after femoral artery catheterization results in consistently low rates of major complications. A rare complication of femoral artery catheterization is arterial infection. Its occurrence after diagnostic angiography using manual compression has not been reported. We report two cases of femoral arterial infection after uneventful diagnostic catheterization in nonimmunocompromised patients using the Perclose percutaneous arterial closure device. Our cases are representative of Perclose associated infections, with delayed presentation of a staphylococcal arterial infection requiring arterial debridement and reconstruction. This article indicates that Perclose use carries a risk of severe arterial infection. Surgeons should be aware of the potential infectious complications associated with Perclose use and the need for aggressive treatment.

[Intravascular laser irradiation of blood in multimodal treatment of patients with obliterating diseases of the lower limb vessels]. / Vnutrisosudistoe lazernoe obluchenie krovi v kompleksnom lechenii bol'nykh s obliteriruiushchimi zabolevaniiami sosudov nizhnikh konechnostei.

The work analyses the results of the multimodality treatment of 80 patients among whom 20 suffered from endarteritis obliterans and 60 from atherosclerosis obliterans of the lower limb vessels. In the process of complex treatment intravascular laser irradiation of blood (ILIB) was carried out by introducing the light guide into a peripheral vein. In 31 (73.8%) patients with decompensated circulatory disorders in the limbs, a course of ILIB produced a good clinical effect. A positive effect was encountered in 35 (92.1%) of patients with subcompensated circulatory disorders in the lower limbs. The clinical efficacy of ILIB is due to normalization of blood coagulative properties, increase of the fibrinolytic potential, improvement of hemorheology, and normalization of the lipoprotein ratio.

[Roentgeno-surgical treatment of vascular occlusive diseases of the lower extremities]. / Rentgenokhirurgicheskoe lechenie okkliuzionnogo porazheniia sosudov nizhnikh konechnostei v stadii tiazheloi ishemii.

The methods of direct revascularization of the lower extremities in occlusive-stenotic lesion at the stage of severe ischemia were used in 144 patients. Of them in 35, simultaneously or with a several day interval, the ++roentgeno-endovascular dilatation (RED) in the several segments of the arterial bed was carried out, in 36--RED was performed in combination with 2-3 procedures of plasmapheresis, in 16 patients in occlusion to a large extent, the isolated balloon profundoplasty was performed, in 46 patients with total lesion of the vessels--isolated RED of the aorto-iliac segment. This contributed to increase in the effectiveness of the collateral blood flow in the vessels of the lower extremities. A high effectiveness of the methods employed was noted in follow-up of from 1 to 5 years. The indications for the use of RED and causes of failures are presented.

[Outpatient electromagnetic therapy combined with hyperbaric oxygenation in arterial occlusive diseases]. / Magnitoterapiia v komplekse s giperbaricheskoi oksigenatsiei pri obliteriruiushchikh zabolevaniiakh arterii v poliklinike.

The authors first applied hyperbaric oxygenation (HBO) in the outpatient clinic in 1968. Barotherapy was conducted in 107 outpatients whose ages ranged from 27 to 80 years; they had various stages of the disease of 5- to 20-year history. In 70 patients treated for obliterating diseases of the vessels by HBO in a complex with magnetotherapy by means of magnetophors, the remission lasted 1-2 years; patients treated by HBO alone had a 3-8 month remission. A prolonged positive effect was produced in 64 patients. The suggested effective and safe method is an additional one to the existing means of treating this serious and progressive disease, which can be applied successfully in outpatient clinics.
