Deep vein thrombosis (DVT) is associated with a high cost burden for health care systems because of secondary cost intensive complications like pulmonary embolism and especially the post thrombotic syndrome (PTS). The current standard therapy of anticoagulation for DVT therapy has not changed through the years leaving patients especially with iliofemoral vein thrombus on a high-risk situation for developing PTS. Current study situation for endovascular treatment of iliofemoral DVT treatment gives a rationale for active thrombus removal using catheter directed therapy (CDT) or pharmacomechanical thrombectomy (PMT) which improves valvular vein function and luminal patency reducing the potential complication of PTS...

Thromboprophylaxis is not well defined after liver transplantation (LT). The aim of this study was to evaluate the incidence of splanchnic vein thrombosis (SVT) and nonsplanchnic vein thrombosis (NSVT) after LT. Liver transplantations performed between 2009 and 2013 in our institution were reviewed. Demographic, intraoperative, and postoperative data were recorded. Low-molecular-weight heparin was only administered postoperatively if intraoperative thrombectomy was performed or in patients preoperatively anticoagulated...

OBJECTIVE: Current percutaneous thromboembolectomy techniques may obviate surgical intervention in high-risk patients with iliocaval thrombus or thrombus of the right side of the heart, but typically require thrombus fragmentation and thrombolysis with associated bleeding and thromboembolic complications. The AngioVac (Angiodynamics, Latham, NY USA) device uses a percutaneous venovenous bypass circuit to aspirate intact thrombus. A review of the literature was performed with regard to the AngioVac device to determine the factors correlating with successful thrombus extraction...

OBJECTIVE: Percutaneous mechanical thrombectomy (PMT) is regularly used in the treatment of both venous and arterial thrombosis. Although there has been no formal report, PMT has been linked to cases of reversible postoperative acute kidney injury (AKI). The purpose of this study is to evaluate the risk of renal dysfunction in patients undergoing PMT vs catheter-directed thrombolysis (CDT) for treatment of an acute thrombus. METHODS: This study is a retrospective review of all patients in a single institution with a Current Procedural Terminology code for PMT or CDT from January 2009 through December 2014...

Cerebral venous thrombosis (CVT) has an incidence of 1.32/100,000/years in high-income countries, and higher in middle- and low-income countries. CVT is more frequent in infants and children young adults and females, especially during pregnancy/puerperium. CVT are now being diagnosed with increasing frequency because of the increased awareness and higher use of magnetic resonance imaging (MR) for investigating patients with acute and subacute headaches and new onset seizures. CVT rarely present as a stroke syndrome...

Lindsay Robertson, Olivia McBride, Anne Burdess
BACKGROUND: Deep venous thrombosis (DVT) occurs in approximately one in 1000 adults every year, and has an annual mortality of 14.6%. In particular, iliofemoral DVT can lead to recurrent thrombosis and post-thrombotic syndrome (PTS), a painful condition which can lead to chronic venous insufficiency, oedema, and ulceration. It causes significant disability, impaired quality of life, and economic burden. Early thrombus removal techniques have been advocated in patients with an iliofemoral DVT in order to improve vein patency, prevent valvular dysfunction, and reduce future complications, such as post-thrombotic syndrome and venous ulceration...

Exhaustion of superficial veins coupled with the presence of intrathoracic central venous occlusions remains a significant obstacle for hemodialysis access creation; complex arteriovenous graft (AVG) configurations have been described. The axillary-iliac AVG was first reported in 1987, and few authors have explored this access. We evaluated our experience with this AVG configuration utilizing the early cannulation (EC) graft Flixene™ (Atrium ™, Hudson, NH, USA). Eight patients (75 % men; mean age 37 ± 10 years) with End-Stage Renal Disease (ESRD) underwent axillo-iliac AVG creation with Flixene™ grafts; all had exhausted peripheral veins, occluded thoracic central veins, and inadequate femoral veins...

BACKGROUND: The medial sural artery perforator (MSAP) flap shows advantages for reconstruction in the foot and ankle, where bulk is a liability. We evaluated the versatility of this flap and provide further evidence on its use for covering small-to-moderate size defects by comparing the outcome depending on the region of reconstruction. METHODS: Twenty-two patients with variable defects of 4 × 4 to 18 × 7 cm underwent MSAP flap reconstruction. Final outcomes of all patients were evaluated 12-months postoperatively using the AOFAS ankle-hindfoot, midfoot and hallux scale for clinical-functional evaluation, and the SF-36 health survey for quality-of-life measurement...

Deep venous thrombosis (DVT) is a common disorder with a significant mortality rate. Successful endovascular treatment of acute DVT is most likely to be achieved in patients with recently formed thrombus, (<10-14 days) with acute iliofemoral DVT. Endovascular treatment options include: Catheter-directed thrombolysis (CDT), pharmacomechanical catheter-directed thrombolysis (PCDT), percutaneous aspiration thrombectomy (PAT), vena cava filter protection, venous balloon dilatation and venous stent implantation...

BACKGROUND: The risk of deep venous thrombosis is elevated during pregnancy and the puerperium. Therapy is usually limited to conservative measures as invasive thrombus removal is feared because of possible complications. However, leg- or life-threatening situations require fast thrombus removal, and the long-term rate of post-thrombotic syndrome (PTS) may be reduced by venous recanalization. Our center's experience may give support to surgical venous thrombectomy (VT). METHODS: Between 1996 and 2016, all women who received VT for pregnancy-related deep venous thrombosis in our department were included...

Neonatal hemostasis differs qualitatively, but in particular quantitatively, from hemostasis in older children and adults. Nevertheless, hemostasis in healthy neonates is functionally stable with no tendency to bleeding or thrombotic complications. In sick neonates, however, risk factors may disrupt this equilibrium and lead to thrombosis. The most important risk factor is the central venous catheter. Management of neonatal central venous catheter thrombosis is challenging, as no controlled trials have been performed...

Venous thromboembolic disease is a major cause of morbidity in cancer patients. The Perspective database was used to identify patients with solid tumors and a diagnosis of VTE from 2006 to 2012. We examined use of IVC filters, thrombolysis, and thrombectomy. Among 32,545 patients, 23.1% received an IVC filter, 1.9% thrombolytic therapy, and 0.4% underwent thrombectomy. Use of IVC filters decreased between 2006 and 2012 (23.4% to 21.2%, p = 0.012). Older patients, uninsured patients, Hispanics, and those with more comorbidities were more likely to undergo filter placement while patients at rural hospitals were less likely to receive an IVC filter (p < 0...
