Portal vein (PV) thrombosis (PVT) in the absence of liver disease or thrombophilia is rare. We report a 57-year-old male with a history of stage 3 chronic kidney disease who presented at the emergency department 18 months after abdominal surgery with progressive abdominal pain and distention. Computed tomography revealed PVT with multiple collaterals and moderate ascites. He had undergone partial gastrectomy and gastrojejunal anastomosis at an outside facility for gastrointestinal stromal tumors that caused an iatrogenic stenotic lesion in the PV...

Arterial pseudoaneurysms are relatively rare complications of the vascular system. Many cases may remain asymptomatic for a lifetime only to be discovered incidentally, whereas others may cause fatal hemorrhage. Majority of cases present with local compressive symptoms. Rarely, it has been implicated as an etiology for gastrointestinal (GI) bleed by eroding into an adjacent bowel, with splanchnic pseudoaneurysm being more commonly responsible as compared to peripheral ones. Although rare, they are an important consideration because of the high mortality rate...

The effect of hyperlipidemia on the systemic production of cytokines was evaluated in the plasma of rats after anterior abdominal wall reconstruction with polypropylene (Esfil) and polytetrafluorethylene (Ecoflon) endoprostheses. The reference group was formed from animals without hyperlipidemia, in which anterior abdominal wall plasty was carried out with the use of the same endoprostheses. Intact rats without hyperlipidemia and intervention served as the control. Hypercytokinemia was detected on days 1-10 after reconstructive surgery on the anterior abdominal wall...

Titanium and polypropylene mesh endoprostheses were implanted into the rat abdominal cavity and the populations of cells migrating to their surface were analyzed. On both materials, the cells were presented mainly by macrophages that proliferated, activated, and fused to form multinuclear cells. Contact with the foreign surface triggered superoxide anion generation and myeloperoxidase synthesis by macrophages (these processes were more intense on polypropylene implants than on titanium ones) and stimulated production of nitric oxide by macrophage...

The Ovation Abdominal Stent Graft System is a trimodular endoprosthesis planned to overcome the limitations of currently available stent grafts, allowing through complex iliac and femoral access and providing a proximal seal in challange infrarenal neck morphology. The proximal sealing is achieved by means of a network of inflatable rings filled with low-viscosity radiopaque polyethylene glycol (PEG) based polymer during stent graft deployment. The leakage of polymer outside the channel to fill the rings into the vascular system may induce an hypersensitivity reaction and anaphylactic shock...

INTRODUCTION: Comparatively to open repair, endovascular aneurysm repair has reduced transfusion rates but thereâs no recommendation about number of red blood cells units to be crossmatched preoperatively. Our aim is contribute to the analysis of red blood cells units needs in endovascular and hybrid aortic aneurysm repair and developing a protocol for maximum surgical blood orders schedule. MATERIAL AND METHODS: We retrospectively analyzed our prospective database of elective endovascular aneurysm repair from 2001 to 2012...

BACKGROUND: In the young patient, treatment of post-traumatic elbow arthritis remains difficult. Total elbow arthroplasty must be delayed for as long as possible. Therapy starts with nonoperative treatment. If this fails, operative options can be discussed. TREATMENT AIM: The aim of surgery is to provide a functional range of motion with acceptable pain without obstructing future treatment options. THERAPY: Patients with pain at terminal extension and/or flexion may benefit from arthroscopic or open debridement...

Introduction/Background: With extended life expectancy, the number of primary joint arthroplasties has also increased. Revision surgery is also more often necessary, due to aseptic or septic loosening of the prosthesis or periprosthetic fracture. Large bone defects often occur in these patients and several non-modular, conventional implants are available to handle this difficult situation. Custom made implants offer an individually designed and defect-adapted shape with perfect covering of the lesion, but may delay the operation...

BACKGROUND AND AIMS: Anastomotic bile leaks are common after orthotopic liver transplant (OLT), and standard treatment consists of placement of a biliary endoprosthesis. The objectives of this study were to identify risk factors for refractory anastomotic bile leaks and to determine the morbidity associated with refractory bile leaks after OLT. METHODS: Consecutive adult patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) for treatment of post-OLT biliary adverse events between 2009 and 2014 at a high-volume transplant center were retrospectively identified...

Improvements in imaging and treatment of musculoskeletal tumors have increased the variety of options for reconstruction following joint-sparing diaphyseal resection. The purpose of this case series was to show that reconstruction of malignant tumors of the radial shaft with an intercalary prosthesis may be an option for patients with segmental bone loss. Three consecutive patients underwent wide resection of the radial diaphysis followed by reconstruction with a custom intercalary prosthesis. A custom intercalary prosthesis with lap joint design was used in all 3 cases...

The revision of the two phase treatment represents a golden standard in the treatment of infected endoprosthesis. Throughout this study, the results of 21 patients with an infected hip endoprosthesis treated in two phases have been processed, with the use of an antibiotic spacer, within the period of 2009 and 2012. Thereby, a unique protocol for diagnosis and treatment of infections has been applied to all the patients, which entails a preoperational x-ray image, laboratory findings (Se, CRP), as well as a puncture aspiration with a microbiological and biochemical examination of the aspirated fragments...

Thoracic aorta mural thrombosis (TAMT) is uncommon pathology with potentially catastrophic complications due to recurrent spontaneous distal embolization. Best treatment , medical or surgical, is still under debate especially in high risk patients. Endovascular approach by means of thoracic endoprosthesis seems to be feasible and minimally invasive treatment option. We report a successful treatment of symptomatic TAMT using a thoracic aortic stent graft in high risk patient for open repair and contraindication to systemic anticoagulation...

CONTEXT: Endovascular aneurysm repair (EVAR) has become the preferred approach for the treatment of infrarenal abdominal aortic aneurysm (IRAAA) in detriment of Open Surgical Repair (OSR). EVAR results in lower mortality rates within 30 days, but rates tend to be the same after longer periods. Moreover, reduced use of hospital resources with EVAR does not necessarily offset the costs of the endoprosthesis. OBJECTIVES: To estimate hospital expenses after OSR or EVAR, including early and late re-admissions...
