INTRODUCTION: A primary aortoenteric fistula (PAEF) is a communication between aorta and the gastrointestinal tract. It is a rare condition that is difficult to diagnose and therefore associated with a high mortality. PRESENTATION OF CASE: We report a rare case of a 66-year old man with an unstable bleeding PAEF. A salvage procedure was performed with a covered stent. Later, a sigmoidectomy was performed with resection of the fistula. Postoperatively, the patient suffered an infection that was treated well with antibiotics and he was discharged two weeks later with complete resolution of the fistula...

OBJECTIVE/BACKGROUND: The aim is to present current results of open complex aortic repair in patients with connective tissue disease (CTD). METHODS: This was a retrospective cross-border, single centre study. From February 2000 to April 2016 72 aortic operations were performed on 65 patients with CTD (41 male, median age 41 years [range 19-70 years]). Fifty-six patients (86%) underwent at least one previous aortic repair (71 open, four endovascular), including 33 patients (51%) operated before at the site of the procedure reported here...

Aortic cross-clamping induced ischemia reperfusion (IR) is an important factor in development of postoperative acute cardiac injury following abdominal aortic surgery. We investigated the possible antioxidant/anti-inflammatory effects of fluoxetine (FLX), which used widely as a preoperative anxiolytic, on cardiac injury induced by IR of infrarenal abdominal aorta. FLX was administered to IR (60-min ischemia and 120-min reperfusion) performed rats for 3 days, once daily at 20 mg/kg, i.p. dosage. Results were compared to control and non-FLX treated IR performed rats...

BACKGROUND: Thoracic endovascular aortic repair is characterized by a substantial need for reintervention. Secondary open aortic procedure becomes necessary when further endoluminal options are exhausted. This synopsis and quantitative analysis of available evidence aims to overcome the limitations of institutional cohort reports on secondary open aortic procedure. METHODS AND RESULTS: Electronic databases were searched from 1994 to the present date with a prospectively registered protocol...

Introduction-patients: Takayasu arteritis may involve various parts of the aorta and its major branches. It leads to occlusive or aneurysmal disease of the vessel. It can be treated either with surgery or percutaneous intervention. We report a successful endovascular treatment of stenosis of the descending thoracic and abdominal aorta in a 19-year-old female. Methods-results-conclusions: Self-expandable nitinol stent was deployed and adequate opening of the aorta was obtained in this patient. Long-term durability of endovascular approach is a matter of debate...

: Aneurysms of the descending thoracic and thoracoabdominal aorta are life-threatening conditions. All aneurysms which have not yet had an indication for the treatment need regular follow-up to prevent rupture or dissection. We present a case of a patient with a giant aneurysm of the thoracoabdominal aorta who was denied both surgery and endovascular treatment.

A 62-years-old female had undergone ascending aortic replacement with homograft for graft infection and mediastinitis after initial replacement of ascending aorta due to acute type A dissection. Ten years after homograft replacement, follow up computed tomography showed acute growing saccular aneurysm of the homograft without infectious symptoms. We urgently performed Bentall procedure and hemiarch replacement successfully. Pathological diagnosis was true aneurysm of the homograft. She was discharged from hospital without any complication and has been quite uneventful 7 years after surgery...

Quadricuspid aortic valve is a rare congenital disease. We experienced 3 surgical cases of quadricuspid aortic valve. Patient 1 was a 72-year-old man who was noted to have a quadricuspid aortic valve associated with aortic regurgitation and an ascending aortic aneurysm(51 mm in diameter). He underwent replacement of the aortic valve and the ascending aorta. Patient 2 was a 71-year-old man with severe aortic stenosis, regurgitation, and coronary triple vessel disease. He underwent aortic valve replacement and coronary artery bypass grafting...

BACKGROUND: Recently, it was reported that angiopoietin-like protein 2 (ANGPTL2) secreted from a pathologically stressed heart accelerates cardiac dysfunction in an autocrine/paracrine manner, and that suppression of ANGPTL2 production in the heart restored cardiac function and myocardial energy metabolism, thereby blocking heart failure (HF) development. Interestingly, circulating ANGPTL2 concentrations reportedly increase in HF patients, suggesting a possible endocrine effect on cardiac dysfunction...

Thoracic endovascular aortic repair (TEVAR) is commonly applied in type-B aortic dissection. For patients with dissection affects descending aorta and extends downward to involve abdominal aorta and possibly iliac arteries, false lumen (FL) expansion might occur post-TEVAR. Predictions of dissection development may assist in medical decision on re-intervention or surgery. In this study, two patients are selected with similar morphological features at initial presentation but with different long-term FL development post-TEVAR (stable and enlarged FL)...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

BACKGROUND: Temporary hepatic ischemia is inevitable during open aortic surgery when supraceliac clamping is necessary, as in thoracoabdominal or pararenal aneurysms. Remote ischemic preconditioning (RIPC) has been described as a potential protective means against ischemia - reperfusion injury (IRI) in various tissues including the liver. The aim of this experimental study was to detect the effect of RIPC on liver IRI in a model of supraceliac aortic cross-clamping. METHODS: An animal study was performed...

BACKGROUND: In January 2015 we created a multidisciplinary Aortic Center with the collaboration of Vascular Surgery, Cardiac Surgery, Interventional Radiology, Anesthesia and Hospital Administration. We report the initial success of creating a Comprehensive Aortic Center. METHODS: All aortic procedures performed from January 1, 2015 until December 31, 2016 were entered into a prospectively collected database and compared with available data for 2014. Primary outcomes included the number of all aortic related procedures, transfer acceptance rate, transfer time and proportion of elective/emergent referrals...

Bleeding is a serious concern during surgery for acute aortic dissections. We have used Hydrofit and Surgicel together to achieve hemostasis at the graft anastomotic sites during replacement of the ascending aorta and aortic arch. Complete hemostasis was achieved without further need for any additional sutures.

OBJECTIVES: Previously published studies showed that the standard tumor-to-blood standardized uptake value (SUV) ratio (SUR) was a more accurate prognostic method than tumor maximum standardized uptake value (SUVmax). This study evaluated and compared prognostic value of positron emission tomography (PET) parameters and normalized value of PET parameters by blood pool SUV in non-small-cell lung cancer (NSCLC) patients who received curative surgery. METHODS: Seventy-seven patients who underwent curative resection for NSCLC between January 2010 to December 2013 were enrolled in this study...

Isolated supravalvular aortic stenosis in adults is a rare form of left ventricular outflow tract obstruction. We describe a case in a 41-year-old man in whom the supravalvular aorta had narrowed to approximately the size of the left anterior descending coronary artery. The patient underwent aortic surgery with replacement of the ascending aorta and repair of supravalvular aortic stenosis with a pantaloon graft. A postoperative echocardiogram showed substantial improvement: the mean gradient across the aorta had fallen from 48 to 8 mmHg...

Invasion of a renal cell carcinoma thrombus into the inferior vena cava and right atrium is infrequent. Reaching and completely excising a tumor from the inferior vena cava is particularly challenging because the liver covers the surgical field. We report the case of a 61-year-old man who underwent surgery for a renal cell carcinoma of the right kidney that extended into the inferior vena cava and right atrium. During dissection of the liver to expose the inferior vena cava, transesophageal echocardiograms revealed right atrial mass migration into the tricuspid valve...

Polyester is commonly used in vascular surgery for patch angioplasty and grafts. We hypothesized that polyester patches heal by infiltration of arterial or venous progenitor cells depending on the site of implantation. Polyester patches were implanted to the Wistar rat aorta or inferior vena cava and explanted on days 7 or 30. Neointima that formed on polyester patches was thicker in the venous environment compared to the amount that formed on patches in the arterial environment. Venous patches had more cell proliferation and greater numbers of VCAM-positive and CD68-positive cells, whereas arterial patches had greater numbers of vimentin-positive and alpha-actin-positive cells...

Hemosuccus pancreaticus is a rare cause of gastrointestinal bleeding in which haemorrhage occurs from the ampulla of vater via the pancreatic duct, mostly from ruptured pseudoaneurysms. Our patient is a 25-year-old Filipino male who presented with intermittent epigastric pain associated with melena and decreasing haemoglobin despite multiple blood transfusions. EGD showed erythematous gastric and duodenal mucosa with no evidence of active bleeding. Whole abdominal CT scan with IV contrast showed diffusely prominent pancreas with areas of non-enhancement suggestive necrosis...
