OBJECTIVES: To assess enhancement patterns of sporadic insulinomas on volume perfusion CT (VPCT), and to identify timing of optimal tumour-parenchyma contrast. METHODS: Consecutive patients who underwent VPCT for clinically suspected insulinomas were retrospectively identified. Patients with insulinomas confirmed by surgery were included, and patients with familial syndromes were excluded. Two radiologists evaluated VPCT images in consensus. Tumour-parenchyma contrast at each time point was measured, and timing of optimal contrast was determined...

: Laparoscopic surgery (LS) is the minimally invasive alternative to open surgery and endovascular approach for treating major aortic diseases. Only few reports in the literature describe the long-term outcomes of the laparoscopic approach for major vascular diseases. Furthermore, the widespread use of endovascular techniques has limited the use of LS to wellselected patients. This review evaluated the results of LS for aortic disease and compared the clinical outcomes of laparoscopic technique with those of open and endovascular surgery...

Epiaortic ultrasound is an imaging modality that is commonly used to evaluate the ascending aorta for atheroma and other mural lesions during elective cardiac surgery. Its use in contained aortic rupture has not been established. We present a case of thoracic trauma with contained pseudoaneurysm of the ascending aorta. At operation, the precise location of the aortic tear could not be identified by visual inspection, manual palpation, or transesophageal echocardiography. Epiaortic ultrasound was employed and the aortic defect was identified and successfully repaired...

Paraplegia caused by spinal cord ischemia is a severe complication following surgeries in the thoracic aneurysm. HMGB1 has been recognized as a key mediator in spinal inflammatory response after spinal cord injury. Electroacupuncture (EA) pretreatment could provide neuroprotection against cerebral ischemic injury through inhibition of HMGB1 release. Therefore, the present study aims to test the hypothesis that EA pretreatment protects against spinal cord ischemia-reperfusion (I/R) injury via inhibition of HMGB1 release...

Ischemia-reperfusion injury is the major complication of abdominal aortic surgery, and it mainly affects the lower extremities and remote organs. In the present study, the electrophysiological alterations in diaphragm that underlie the post-operative respiratory dysfunction were investigated. Wistar Albino rats were randomly divided into two groups: SHAM (only laparotomy was performed) and IR (abdominal aorta was clamped for 30min and reperfused for 2h). Following the operational period diaphragm muscles were isolated and electrophysiological experiments were carried out in-vitro...

Objective: Introduce the low-cost and easy to purchase simulator without biological material so that any institution may promote extensive cardiovascular surgery training both in a hospital setting and at home without large budgets. Methods: A transparent plastic box is placed in a wooden frame, which is held by the edges using elastic bands, with the bottom turned upwards, where an oval opening is made, "simulating" a thoracotomy. For basic exercises in the aorta, the model presented by our service in the 2015 Brazilian Congress of Cardiovascular Surgery: a silicone ice tray, where one can train to make aortic purse-string suture, aortotomy, aortorrhaphy and proximal and distal anastomoses...

BACKGROUND: In the patients with longer-segment aortic arch hypoplasia or interruption with ventricular septal defect, surgery with homograft vessel or autologous pericardial patch to augment descending aortic arch will not result in adverse reactions caused by end-to-end anastomosis. In this study, we retrospectively analyzed primary experience of surgical correction of complicated aortic arch anomaly with autologous main pulmonary artery. METHODS: From July 2010 to March 2016, the twenty-one cases of aortic arch complex anomalies were reconstructed with autologous main pulmonary artery...

OBJECTIVES: We hypothesized that antegrade open stent graft implantation in the descending aorta during acute type A aortic dissection surgery is safe and improves patient outcome compared with the standard repair technique. METHODS: Hundred and forty-one consecutive patients underwent surgery for acute type A aortic dissection at our institution from 2010 to 2016. Of those, 104 patients underwent ascending aorta and hemiarch repair under hypothermic circulatory arrest with antegrade cerebral perfusion (standard group)...

Heart failure is one of the leading causes of death worldwide. It is a complex clinical syndromethat includes fatigue, dyspnea, exercise intolerance, and fluid retention. Changes in myocardial structure, electrical conduction, and energy metabolism develop with heart failure, leading to contractile dysfunction, increased risk of arrhythmias, and sudden death. Hypertensive heart disease is one of the key contributing factors of cardiac remodeling associated with heart failure. The most commonly-used animal model mimicking hypertensive heart disease is created via surgical interventions, such as by narrowing the aorta...

PURPOSE: Risk stratification is of utmost importance for patients with infective endocarditis (IE) who need surgery. However, for these critically ill patients, aspecific scoring systems are used to predict the risk of death after surgery. The aim of this study was both to analyze the risk factors for in-hospital death, which complicates surgery for IE and to create a mortality risk score based on the results of this analysis. METHODS: Outcomes of 138 consecutive patients (mean age 60...

The proper proximal landing zone is a key element for success of endografting in thoracic aortic pathology. If coverage of innominate artery is unavoidable for safe proximal landing, arch debranching surgery is necessary to recruit supra-aortic blood flow before endografting. However, calcified or adhesive ascending aorta makes it difficult to clamp ascending aorta for anastomosis in the first step of arch debranching surgery. We present a novel "no clamp complete parachute technique" to complete this challenging anastomosis...

OBJECTIVES: Endovascular repair of traumatic injury of the aortic isthmus is a safe technique that has shown good short-term results. However, the future of these stent grafts remains unexamined, especially in relation to young patients. METHOD: Between January 2000 and December 2014, 60 patients were treated with endovascular aortic stent graft for injury of the aortic isthmus. Follow-up was done by computed tomography scans with intravenous contrast or magnetic resonance imaging associated with a chest X-ray in order to control the stent graft...

The ability to quantify patient-specific hospital mortality risk before the Norwood procedure remains elusive. This study aimed to develop an accurate and clinically feasible score to assess the risk of hospital mortality in neonates undergoing the Norwood procedure. All patients (n = 549) in the publically available Pediatric Heart Network Single Ventricle Reconstruction trial database were included in the analysis. Patients were randomly divided into a derivation (75%) and validation (25%) cohort. Preoperative factors found to be associated with mortality upon univariable analysis (P < 0...

BACKGROUND: Altered coronary blood flow occurs in patients with coronary artery disease (CAD). Adenosine strongly impacts blood flow mostly via adenosine A2A receptor (A2AR) expressed in coronary tissues. As part of a systemic regulation of the adenosinergic system, we compared A2AR expression in situ, and on peripheral blood mononuclear cells (PBMC) in CAD patients. METHODS AND RESULTS: Aortic and coronary tissues, and PBMC were sampled in 20 CAD patients undergoing coronary artery bypass surgery and consecutively included...
