Introduction: Type A aortic dissection can present with malperfusion syndrome. Lower limb ischaemia may resolve with repair of the dissection; however, the long duration of repair and/or persistent ischaemia may leave tissue at risk of necrosis with potential for substantial morbidity. Report: Here, the case of a 67 year old man who presented with a Type A aortic dissection with malperfusion of the lower extremities is described. The Vascular Surgery and Cardiac Surgery divisions were consulted simultaneously...

OBJECTIVE: When an autogenous vein is harvested and used for arterial bypass, it suffers physical and biologic injuries that may set in motion the cellular processes that lead to wall thickening, fibrosis, stenosis, and ultimately graft failure. Whereas the injurious effects of surgical preparation of the vein conduit have been extensively studied, little is known about the influence of the clinical environment of the donor leg from which the vein is obtained. METHODS: We studied the cellular responses of fresh saphenous vein samples obtained before implantation in 46 patients undergoing elective lower extremity bypass surgery...

Descending aorta interruption is an extremely rare congenital defect. Conventional repair with end-to-end anastomoses is often a surgical challenge in view of the extensive collateral vessels that develop on the chest wall and inside the chest cavity. Extra-anatomic bypass is the preferred technique for the surgical repair of this entity, which avoids the network of collateral vessels, enables simultaneous treatment of associated lesions, and in all likelihood reduces morbidity and mortality. Here we describe an extra-anatomic bypass from the ascending aorta to the bilateral iliac arteries in a 24-year-old woman using vascular grafts (MAQUET Holding B...

BACKGROUND: Redo area region operation is associated with a significant morbidity such as neurovascular injury, infection and lymphorrhea. The traditional management of occluded femoro-popliteal grafts often includes redissection of a scarred groin to obtain adequate inflow via the common femoral artery. These procedures are more technically demanding and require more expertise and judgment than the primary operation. We describe a case of using the ipsilateral iliac branch prosthesis of aorto-bifemoral as inflow for iliac-peroneal bypass, avoiding the previous groin incisions, to minimize the local complications related to a redo groin dissection and to decrease the operative time required to obtain an adequate inflow source...

Venous ulcers can be a chronic debilitating condition with a high rate of recurrence. Herein we describe a case of a patient who successfully underwent an arterial bypass for rest pain but returned with lower extremity swelling and venous ulcers. Venography demonstrated a focal common femoral vein stenosis due to scarring from the surgical exposure. This was treated with endovenous stenting and resulted in resolution of the swelling and ulceration.

OBJECTIVES: Warming intravenous fluids is essential to prevent hypothermia in patients with trauma, especially when large volumes are administered. Prehospital and transport settings require fluid warmers to be small, energy efficient and independent of external power supply. We compared the warming properties and resistance to flow of currently available battery-operated fluid warmers. METHODS: Fluid warming was evaluated at 50, 100 and 200 mL/min at a constant input temperature of 20°C and 10°C using a cardiopulmonary bypass roller pump and cooler...

INTRODUCTION: Small bowel intussusception is a rare complication after Roux-en-Y gastric bypass (RYGB) whose incidence tends to increase. This rising could be explained by an increasing bariatric surgery over the last two decades and by a better recognition of this potential complication. PATIENT AND METHODS: We report a case of jejunojejunal intussusception in 33-year-old woman 2 years following a laparoscopic RYGB. She was taken to the operating room for exploratory laparotomy...

It is well known that a heavily calcified mitral valve significantly increases the perioperative and postoperative risks of mitral valve surgery. A 71-year-old woman was referred to our department with severe mitral valve disease. Cardiac imaging revealed extremely severe calcification of the entire left heart. Surgery was performed through a median sternotomy with standard cardiopulmonary bypass. After dilating the mitral orifice with a balloon, we replaced the valve with a transcatheter Edwards Sapiens 3 aortic valve under direct vision...

Aortic sarcoma is a rare entity. In this study, we report a case of a 56-year-old man with complaints of pain and numbness of bilateral lower extremities. An endovascular aortic repair was finally adopted to prevent recurrent embolic events. An endo-biopsy was performed and showed aortic sarcoma. Axillary bifemoral and femoro-femoral cross-over bypass surgeries were taken to supply blood to the lower extremities in the 6th month after the first operation. He finally passed away in the 37th month. Aortic sarcoma should be taken into consideration as one of the possible etiologies for massive thrombus in aorta...

BACKGROUND: There is a paucity of data in regards to longer term morbidity outcomes in Indigenous Australian patients undergoing coronary artery bypass grafting (CABG). No comparative data on re-infarction, stroke or reintervention rates exist. Outcome data following percutaneous coronary intervention (PCI) is also extremely limited. Addressing this gap in knowledge forms the major aim of our study. METHODS: This was a single centre cohort study conducted at the Townsville Hospital, Australia which provides tertiary adult cardiac surgical services to the northern parts of the state of Queensland...

BACKGROUND: Dual antiplatelet therapy (DAPT) usually refers to the administration of aspirin plus a platelet P2Y12 receptor blocker. This combination is commonly prescribed after revascularization procedures in patients with peripheral arterial disease (PAD) to prevent failure of the intervention. However, there is not a consensus among peripheral vascular specialists regarding whether the optimal treatment regimen for their patients is mono antiplatelet therapy (MAPT) or DAPT. Furthermore, there is no consensus regarding the optimal duration of DAPT...

Occlusive artery disease (CAD) is the leading cause of death worldwide. Bypass graft surgery remains the most prevalently performed treatment for occlusive arterial disease, and veins are the most frequently used conduits for surgical revascularization. However, the clinical efficacy of bypass graft surgery is highly affected by the long-term potency rates of vein grafts, and no optimal treatments are available for the prevention of vein graft restenosis (VGR) at present. Hence, there is an urgent need to improve our understanding of the molecular mechanisms involved in mediating VGR...

Background: Popliteal artery entrapment syndrome (PAES) is a very rare pathology that can cause lower extremity ischemia in healthy young people. Anomalous anatomic relationships between the popliteal artery (PA) and the surrounding musculo-tendinous structures cause PAES. We present 31 patients with PAES in 35 limbs that were treated surgically in our clinic within a 12-year period. Patients and Methods: From 2001 to 2015, 31 patients (mean age: 32 ± 7.4 years) underwent surgery for PAES...

The progression of cystic fibrosis (CF) from an acute to a chronic disease is often associated with the conversion of the opportunistic pathogen Pseudomonas aeruginosa from a nonmucoid form to a mucoid form in the lung. This conversion involves the overproduction of the exopolysaccharide alginate, whose production is under control of the AlgT/U sigma factor. This factor is regulated posttranslationally by an extremely unstable process and has been commonly attributed to mutations in the algT/U gene. By exploiting this unstable phenotype, we isolated 34 spontaneous nonmucoid variants arising from the mucoid strain PDO300, a PAO1 derivative containing the mucA22 allele commonly found in mucoid CF isolates...

BACKGROUND: Patients with peripheral arterial disease (PAD) often have high comorbidity burden that may complicate post-interventional course and drive increased healthcare expenditures. Racial disparity had been observed in lower extremity revascularization (LER) patterns and outcomes. In 2014, Maryland adopted an all-payer rate setting system to limit the rising hospitalization costs. This resulted in an aggregate payment system in which hospital compensation takes place as an overall per capita expenditure for hospital services...
