Acute mesenteric ischemia is a rare life-threatening condition that accounts for approximately one in 1000 hospital admissions. The mortality rate is 50%-69% owing to the absence of specific symptoms and laboratory data, which makes early detection of this condition difficult. If the use of contrast material is possible, biphasic contrast material-enhanced multidetector computed tomography (CT) is the first-line imaging test for early diagnosis of the disease and for differentiation from other causes of acute abdomen...

BACKGROUND: Renal cell carcinoma (RCC) are accompanied by inferior vena cava (IVC) thrombus in up to 10% of the cases, with surgical resection remaining the only curative option. In case of IVC wall invasion, the operative procedure is more challenging and may even require IVC resection. This study aims to determine the diagnostic performance of contrast-enhanced magnetic resonance imaging (MRI) for the assessment of wall invasion by IVC thrombus in patients with RCC, validated with intraoperative findings...

INTRODUCTION: Phlegmasia cerulea dolens (PCD) is a rare complication of deep venous thrombosis (DVT). Massive ileo-femoral DVT is usually the cause and prompt treatment is mandatory as it represents a medical emergency. Reported amputation rates range from 12% to 25% and mortality ranges from 25% to 40%. Limb ischemia results from obstruction to arterial inflow secondary to extreme levels of venous hypertension. Primary treatment goal is restoration of venous outflow and can be achieved by endovascular or surgical techniques...

INTRODUCTION: Creating and maintaining a functional vascular access(VA) is a critical factor in the survival of a dialysis patient. However, it will not function forever, implying a creative attitude from the vascular surgeon either to maintain its functionality or built a new one wherever possible, being it autologous or synthetic. METHODS: Describe the VA history of a 59years-old male with morbid obesity and end-stage chronic kidney disease. RESULTS: His VA construction started in2012 with failed attempts in both forearms until a functional brachiocephalic artery-venous fistula(AVF) in the right upper limb was achieved, but was deemed to ligation as severe venous hypertension secondary to central venous disease related to CVC use...

Cerebral venous sinus thrombosis is sometimes fatal. We describe a case of sinus thrombosis in a 43-year-old woman presenting with generalized seizure, delirium, and a 2 week history of headache and nausea. The patient underwent mechanical thrombectomy using a novel combined approach, in which a Shouryu HR balloon catheter (Kaneka) was anchored in the right transverse sinus (TS), sigmoid sinus (SS), and superior sagittal sinus (SSS), while a Penumbra 5 MAX ACE (Penumbra) catheter was moved back and forth between the right TS, SS, and SSS...

We have used a new device to prevent pulmonary embolism during pharmacomechanical thrombectomy in a 25-year-old postpartum woman. The Angel® catheter (BiO2 Medical Inc., Golden, CO, USA) is a temporary device that combines the functions of a vena cava filter (VCF) with those of a triple-lumen central venous catheter. Normally, a VCF is implanted to prevent pulmonary embolism during pharmacomechanical thrombectomy. However, the complications associated with VCFs increase with time, not all of the filter can always be retrieved, and there can be iatrogenic effects both during implantation and retrieval...

OBJECTIVES: Upper arm arteriovenous fistulas (AVF) occasionally develop high flow. Revision using distal inflow (RUDI) effectively reduces flow of high flow accesses (HFA) in the short-term and is also popularised for treatment of haemodialysis access induced distal ischaemia (HAIDI). The long-term efficacy is unknown. The study's aim was to report on 3 year RUDI patency and recurrence rates for HFA with and without HAIDI. MATERIAL AND METHODS: This was a retrospective cohort study of patients with a HFA with or without HAIDI undergoing RUDI using greater saphenous vein (GSV) interposition between March 2011 and October 2017 at three facilities...

INTRODUCTION: Simultaneous kidney and pancreas transplant is the preferred treatment option for end-stage renal disease due to type 1 diabetic nephropathy. Vascular complications are detrimental to graft survival and can lead to graft loss in the early postoperative phase of transplantation. Generally, duplex Doppler ultrasound is used for vascular patency monitoring and pancreatectomy followed by re-transplantation is required in the majority of cases. Recently, pancreatic graft salvage with non-operative management, including medical anticoagulation and endovascular thrombectomy, in the early postoperative period has been described with success...

Behçet's Disease (BD) is a rare multi-systemic inflammatory disorder classified as a systemic vasculitis of unknown aetiology. Vascular involvement occurs in approximately 5-51.6% cases, affecting venous and arterial vessels. Cardiac involvement is rare in BD (6%). There have been published approximately 93 cases of BD associated with intracardiac thrombosis, with different treatments and courses. We present a case of a 35-year-old spanish male that, after a percutaneous pharmacomechanical thrombectomy with venous stent placement, developed high fever and extensive venous thrombosis despite anticoagulation including intracardiac thrombosis (ICT) in the right ventricle and pulmonary embolism that leaded to the diagnosis of BD...

We report the use of mechanical venous thrombectomy in 2 cases of cerebral venous sinus thrombosis in which the usual first-choice treatment with systemic anticoagulants was contraindicated. Our aim is to present this treatment as an alternative to consider when anticoagulants therapy is too risky or is contraindicated in critically ill patients.

BACKGROUND: Hepatocellular carcinoma (HCC) can be complicated by major vascular invasion, and resection can be beneficial in some patients.1 Some of these patients are traditionally operated under total vascular exclusion (TVE), refrigeration, extracorporeal circulatory bypass, and cardiac surgery, with high morbidity and mortality.2 However, HCC thrombi are not adherent to the venous wall, and with advances in surgical techniques, resection can be simplified and performed during short-duration TVE alone...

Yuki Horita
The objectives of central venous percutaneous transluminal angioplasty are to dilate the venous lesion and to extend the life of arteriovenous fistula for hemodialysis. It is reasonable to perform percutaneous transluminal angioplasty for central venous lesions if this interventional therapy is required to maintain stable dialysis therapy. However, the presence of large fresh thrombus at central venous lesion site represents a contraindication to percutaneous transluminal angioplasty unless the thrombus can first be removed by thrombectomy...

BACKGROUND: Beyond medical therapy, the role of endovascular approach for the management of chronic Venous Thromboembolic (VTE) disease is yet to be defined. To our knowledge, no systematic reviews or guidelines are available that provide information on how to manage this chronic condition. This paper represents the first systematic review of published reports on the use of vacuum-assisted thrombectomy (AngioVac) in treating chronic VTE disease. METHODS: A systematic review of published case-series, individual case-reports, and review articles in MEDLINE, PubMed, and Google Scholar was conducted...

BACKGROUND: Upper extremity deep vein thrombosis represents (UEDVT) 2-3% of all deep vein thrombosis. Catheter directed thrombolysis (CDT) was replaced largely by pharmacomechanical thrombolysis (PMT) in our institution. In this study we compared the immediate and 1-year results as well as the total hospital costs between CDT and PMT in the treatment of UEDVT. METHODS: From 2006 to 2013, 55 patients with UEDVT were treated with either CDT or PMT at Helsinki University Hospital...

BACKGROUND: Cancer patients demonstrate increased risk for venous thromboembolism (VTE), VTE recurrence, and anticoagulation-associated bleeding. Pharmacomechanical thrombolysis (PMT) aand thrombectomy improves venous patency, venous valve function, and quality of life in patients with acute iliofemoral deep vein thrombosis (DVT). It remains unknown whether pharmacomechanical thrombolysis can be used safely in patients with active cancer. We hypothesized that perioperative and short-term outcomes of pharmacomechanical iliofemoral DVT thrombolysis would not differ between patients with cancer and those without cancer...
