Qiulun Lu, Xiuxin Jiang, Cheng Zhang, Wei Zhang, Wencheng Zhang
BACKGROUND: Abdominal aortic aneurysm (AAA) affects more than 5% of the population in developed countries. To study the formation and progression of AAA, we developed a non-invasive method to analyse regional aortic stiffness to monitor the formation and progression of AAA. METHODS: Saline or Angiotensin II (AngII) was subcutaneously infused in apolipoprotein E knockout (ApoE(-/-)) mice for 28 days; a high-resolution imaging system was used to identify changes in arterial stiffness measured by pulse-wave velocity (PWV) and aortic lumen diameter in the suprarenal aorta...

The J curve hypothesis propose that the relation between blood pressure and risk for cardiovascular events is non-linear. Instead of a decreased risk with lower blood pressure, the risk increases at lower blood pressures. This issue has been discussed for many years, and is still a hot topic. The debates have most often had its origin in the question about how far blood pressure should be lowered with antihypertensive drugs.One one hand, we know that many patients with hypertension is not treated to targets according to guidelines and that this contributes to the high risk for cardiovascular diseases in patients with hypertension...

Clostridium septicum is a highly virulent pathogen which is associated with colorectal malignancy, hematological malignancy, immunosuppression, diabetes mellitus and cyclical neutropenia. Presentation may include disseminated clostridial infection in the form of septicemia, gas gangrene, and mycotic aortic aneurysms. We report the case of a 62-year-old female presenting with necrotizing fasciitis of her left thigh and subsequently developing rectal bleeding. While she was being treated with empiric antibiotics, her blood culture was found to be positive for C...

Since the publication of the 2012 guidelines new literature has emerged to inform decision-making. The 2016 guidelines primary panel selected a number of clinically relevant questions and has produced updated recommendations, on the basis of important new findings. In subjects with clinical atherosclerosis, abdominal aortic aneurysm, most subjects with diabetes or chronic kidney disease, and those with low-density lipoprotein cholesterol ≥ 5 mmol/L, statin therapy is recommended. For all others, there is an emphasis on risk assessment linked to lipid determination to optimize decision-making...

Endovascular repair of the abdominal aorta is a method of choice in pronounced concomitant pathology and high risk of open surgical treatment. The article deals with a clinical case report of successful surgical management of a patient with an infrarenal aortic aneurysm, transplanted kidney, chronic renal insufficiency, secondary diabetes mellitus, multifocal atherosclerosis with predominant involvement of coronary arteries and lower-limb arteries, in whom open surgical treatment was associated with high risk...

BACKGROUND: Diabetes is a risk factor for atherosclerotic disease but negatively associated with the development and progression of abdominal aortic aneurysm (AAA). Advanced glycation end products (AGEs) are increased in diabetes and renders the vascular matrix more resistant to proteolysis. We assessed the concentration of AGEs in AAA biopsies obtained from diabetic and nondiabetic patients and hypothesized that (nonenzymatic) glycation of AAA tissue protects against proteolytic breakdown of collagen...

Oculomotor nerve palsy can be due to varied causes that include diabetic neuropathy, myasthenia gravis, brainstem infarction, demyelinating conditions, and cerebral aneurysms. Among the aneurysmal causes of oculomotor nerve palsy, aneurysm of the posterior communicating artery has been observed to be the most common. Pupillary dysfunction is considered to be an important feature of aneurysmal oculomotor nerve paresis. A case of a 7-year-old boy with partial oculomotor nerve palsy with pupillary sparing is being reported here, the etiology of which is tortuous and ectatic distal internal carotid artery...

BACKGROUND: Pleiotropic effects on cardiovascular protection have been suggested in several oral antidiabetic drugs (OAD). The impacts of OADs on aortic aneurysm (AA) growth have been found in animal studies, but the evidence of their beneficial effects for AA protection in human are lacking. We investigated the relationship between OAD therapy and the risk of developing AA. METHODS: We conducted a nested case-control analysis using the database extracted from Taiwan's National Health Insurance Research Database...

BACKGROUND AND AIMS: Although it has become clear that aneurysmal and occlusive arterial disease represent two distinct etiologic entities, it is still unknown whether the two vascular pathologies are prognostically different. We aim to assess the long-term vital prognosis of patients with abdominal aortic aneurysmal disease (AAA) or peripheral artery disease (PAD), focusing on possible differences in survival, prognostic risk profiles and causes of death. METHODS: Patients undergoing elective surgery for isolated AAA or PAD between 2003 and 2011 were retrospectively included...

OBJECTIVES: Reported results of ruptured abdominal aortic aneurysm (rAAA) in patients with antecedent endovascular repair (EVAR) to those presenting with de novo rupture show a similar or slightly improved outcome. The aim of this study was to compare differences in the presentation and outcomes of rAAA with and without prior EVAR. METHODS: A retrospective review of one hundred twenty-one (121) patients with rAAA, ruptured identified two groups. Group A included 17 patients (rAAA n= 17) with antecedent EVAR and Group B consisted of 104 patients (rAAA n= 104) with de novo ruptures, from January 2001 to March 2015 in three teaching hospitals...

Third nerve paralysis has been known to be associated with a wide spectrum of presentation and other associated factors such as the presence of ptosis, pupillary involvement, amblyopia, aberrant regeneration, poor bell's phenomenon, superior oblique (SO) overaction, and lateral rectus (LR) contracture. Correction of strabismus due to third nerve palsy can be complex as four out of the six extraocular muscles are involved and therefore should be approached differently. Third nerve palsy can be congenital or acquired...
