BACKGROUND: Prognostic factors and the standard treatment approach for gynaecological carcinosarcomas have not yet been clearly defined. Although carcinosarcomas are more aggressive than pure epithelial tumours, they are treated similarly. Serous/clear cell and endometrioid components may be predictive factors for the efficacy of adjuvant chemotherapy (CT) or radiotherapy (RT) or RT in patients with uterine and ovarian carcinosarcomas. Heterologous carcinosarcomas may benefit more from adjuvant CT...

We present a case in which intraocular silicone injection for complex retinal detachment resulted in migration and distribution of silicone along the intracranial visual pathway, and ultimately throughout the ventricular system. Misinterpretation of this material as intracranial hemorrhage on outside computed tomography imaging delayed emergent repair of a Type A aortic dissection until the diagnosis was made on repeat imaging. A discussion of this case and salient computed tomography and magnetic resonance imaging characteristics of silicone is provided...

AIMS: Conventional computed tomography (CT) approaches provides limited visualization of the entire endoluminal changes of aortic dissection (AD), which is essential for its treatment. As an important supplement, three-dimensional CT virtual intravascular endoscopy (VIE) can show relevant details. This study aims to determine the value of VIE in displaying the entry tear and intimal flap of AD. METHODS AND RESULTS: Among 127 consecutive symptomatic patients with suspected AD who underwent CT angiography (CTA), 84 subjects were confirmed to have AD and were included in the study...

Matrix metalloproteinases-2 (MMP-2) plays an important role in the pathogenesis of type A aortic dissection (AD). The aim of this study was to evaluate the association of 3 single nucleotide polymorphisms (SNPs) in the MMP-2 gene with type A AD risk and aortic diameters in patients. We performed a case-control study with 172 unrelated type A AD patients and 439 controls. Three SNPs rs11644561, rs11643630, and rs243865 were genotyped through the MassARRAY platform. Allelic associations of SNPs and SNP haplotypes with type A AD and aortic diameters in patients were evaluated...

BACKGROUND: Stanford type-A acute aortic dissection (AAD) is a severe cardiovascular disease demonstrating the characteristics of acute onset and rapid development, with high morbidity and mortality. The available evidence shows that preoperative acute lung injury (ALI) induced by Stanford type-A AAD is a frequent and important cause for a number of untoward consequences. However, there is no study assessing the incidence of preoperative ALI and its independent determinants before Standford type-A AAD surgery in Chinese adult patients...

It is difficult to treat a thrombotic embolism in the common femoral artery or popliteal artery (POP A), i.e., the non-stenting zone. We report a new technique for the treatment of thrombotic embolism in the non-stenting zone using a self-expandable nitinol stent. Case 1 had an external iliac artery (EIA) occlusion that occurred over several months. A self-expandable nitinol stent was placed in the right EIA lesion via a retrograde approach using a distal 9-Fr balloon protection guide catheter in the right femoral artery...

Contrast-enhanced computed tomography (CT) is an effective tool for assessment of thoracic aortic disease in the modern era. Here, we describe a case of Type A aortic dissection incidentally detected by CT in a 63-year old man. Upon more precise imaging with electrocardiography (ECG)-gated CT, the dissection vanished, revealing it to be an aortic motion artifact. This report highlights the importance of motion artifacts mimicking a dissection flap. CT imaging gated with ECG can distinguish a dissection flap from an artifact...

This case illustrates the complexities of performing a primary percutaneous intervention in a patient with chronic Type A aortic aneurysm and dissection with contraindications for surgical management. We also discuss the significant risk that the patient had to overcome to survive an undiagnosed aortic dissection and an acute ST elevation myocardial infarction.

OBJECTIVES: To identify the risk factors for hypoxaemia following surgical repair of acute type A aortic dissection. METHODS: This was a retrospective study of patients treated between October 2013 and December 2014 at the Department of Cardiovascular Surgery, Anzhen Hospital, China. Univariable and multivariable analyses were performed on the clinical data of 160 patients with acute type A dissection and who underwent ascending aortic and arch replacement under deep hypothermic circulatory arrest...

OBJECTIVE: Current study sought to evaluate the effects of obstructive sleep apnea (OSA) plus hypertension (HTN) on prevalent cardiovascular diseases (CVD). DESIGN AND METHOD: This was a cross-sectional study and a total of 1889 subjects were enrolled. The apnea-hypopnea index (AHI) was measured by polysomnography and OSA degree was classified as mild (AHI 5-14.9) and moderate-severe (AHI ≥ 15), and AHI < 5 was considered no-OSA. Mean and lowest oxyhemoglobin saturation (SaO2) was detected by pulse oximetry...

OBJECTIVE: Aortic dilatation and dissection are complications in some Turner syndrome (TS) patients. To better understand vascular nature of aorta before adult, we evaluated several elastic properties of the aorta in adolescent with TS in comparison to healthy controls. DESIGN AND METHOD: Various indices of the vascular function of ascending aorta were assessed prospectively in TS (n = 28), with a mean age of 14.9 ± 3.3 years and age-matched control (n = 18) groups with the transthoracic echocardiography...

Current Hypertension Guidelines emphasize the importance of assessing the presence of preclinical organ damage. In fact, an extensive evaluation of organ damage may increase the number of patients classified at high CV risk and therefore strongly influence the clinical management of patients. Hypertensive heart disease remains to date the form of organ damage for which there is the greatest amount of evidence of a strong independent prognostic significance. In the presence of a chronic pressure overload, a parallel addition of sarcomers takes place with an increase in myocyte width, which in turn increases left ventricular wall thickness; myocyte hypertrophy is also associated with apoptosis, collagen deposition and ventricular fibrosis with an impairment of coronary hemodynamics as well, thus profoundly influencing functional properties of the left (and right) ventricle...

Chronic hypertension can result in deleterious effects on various vascular organs including the heart and vessels. Cardiovascular magnetic resonance (CMR) has the unique advantage of the ability to assess ventricular volumes and function, valvular abnormalities, vascular pathology, myocardial perfusion and tissue characterization with high accuracy and reproducibility and also avoid the risk of radiation. As this is the case, CMR seems to be an ideal method for comprehensive assessment of patients with systemic hypertension...

The central aorta constitutes the main trunk of the systemic arterial tree. It dilates passively with cardiac ejection during systole and then constricts with its recoil function during diastole, thereby regulating blood pressure and blood flow. The central pulsatile hemodynamics affects local hemodynamics within as well as downstream of the aorta (e.g., end organs).The aorta progressively stiffens and dilates with advancing age, and such age-dependent change is accelerated by hypertension. According to the law of Laplace, wall stress depends on the diameter and pressure of the blood vessel...

The successful clinical introduction of various non-invasive imaging modalities has contributed to the establishment of 'acute aortic syndrome', a relatively new clinical syndrome incorporating several disease entities with similar clinical features (at the time of clinical presentation). Aortic dissection (AD) with intimal flap and two aortic channels (true and false lumens) is the most important disease entity in acute aortic syndrome. Clinical characteristics of AD have been established, with standardized treatment strategies depending on the affected site of the aorta...

Epigastric pain is a common symptom in the emergency department. Most epigastric pain is not fatal, except in acute myocardial infarction, aortic dissection, and abdominal aneurysm rupture. Epigastric pain can also be the only symptom of isolated spontaneous gastric artery dissection. We report the case of a 51-year-old woman diagnosed with neurofibromatosis who initially presented with only epigastric pain. She was initially misdiagnosed with gastritis, treated conservatively, and discharged. Two hours later, she returned to the emergency department with persistent epigastric pain and rebound tenderness in the epigastric area...

BACKGROUND: How to choose the proximal landing zone in endovascular interventions for a patient with a patent retrograde false lumen in dissection of the ascending aorta and aortic arch remains unclear. This study sought to report the safety and efficiency of inducing thrombosis of the retrograde false lumen to enhance a proximal landing zone to treat retrograde type A aortic dissection. METHODS: This study included 9 patients with retrograde type A aortic dissection treated with a 2-stage operation strategy between January 2015 and January 2016...
