Inferior vena cava (IVC) filters are medical devices designed to provide a mechanical barrier to the passage of emboli from the deep veins of the legs to the heart and lungs. Despite decades of development and clinical use, IVC filters still fail to prevent the passage of all hazardous emboli. The objective of this study is to (1) develop a resolved two-way computational model of embolus transport, (2) provide verification and validation evidence for the model, and (3) demonstrate the ability of the model to predict the embolus-trapping efficiency of an IVC filter...

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...

We sought to comprehensively assess the efficacy of Intermittent Pneumatic Compression (IPC) in patients undergoing gynecologic surgery. A computerized literature search was conducted in Pubmed, Embase and Cochrane Library databases. Seven randomized controlled trials involving 1001 participants were included. Compared with control, IPC significantly lowered the deep vein thrombosis (DVT) risk [risk ratio (RR) = 0.33, 95% confidence interval (CI): 0.16 - 0.66]. The incidence of DVT in IPC and drugs group was similar (4...

BACKGROUND: Cytoreductive surgery and heated intraperitoneal chemotherapy (CS/HIPEC) is performed for selected indications at a limited number of specialized centers worldwide. Currently there is no standardized approach to the perioperative care process. We sought to capture current practices in the perioperative management of patients who undergo CS/HIPEC at high-volume centers. METHODS: Surgeon members of the American Society of Peritoneal Surface Malignancies working at high-volume CS/HIPEC centers (>10 cases/year) were invited to complete an online survey...

Extended-duration pharmacological thromboprophylaxis, for at least 28 days, is effective for the prevention of symptomatic venous thromboembolism (VTE) in high-risk surgical patients but is of uncertain benefit in hospitalized medical patients. We aimed to evaluate the efficacy and safety of extended-duration thromboprophylaxis in hospitalized medical patients. We conducted a systematic PubMed, Medline and EMBASE literature search until June 2016 and a meta-analysis of randomized controlled trials which compared extended-duration with short-duration thromboprophylaxis in hospitalized medical patients...

Thromboembolic events including cerebral thrombosis, deep vein thrombosis, and pulmonary embolism are major complications in β-thalassemia. Damaged red blood cells and chronic platelet activation in splenectomized β-thalassemia/HbE patients were associated with increased microparticles (MPs) releases into blood circulation. MPs are small membrane vesicles, which play important roles on coagulation. However, the role of MP in thalassemia is poorly understood. In this study, the effects of splenectomized-MPs on platelet activation and aggregation were investigated...

Tuberculosis is a common infectious disease with a high prevalence in developing countries and presents a major public health issue. Internal jugular vein (IJV) thrombosis is a rare complication in tuberculous cervical lymphadenopathy. We report a case of 26-year male patient with a history of low-grade evening rise in fever, dry cough, loss of appetite, and loss of weight with swelling in lower neck on right side. Ultrasonography (USG) neck showed well-defined hypoechoic lymph nodes posterior to right IJV and common carotid artery in the lower neck at level IV and in the right supraclavicular region showing central necrotic areas with adjoining IJV thrombosis...

Femoral artery injuries are a rare complication of blunt trauma in children that require expeditious diagnosis and treatment to prevent permanent limb dysfunction. Point-of-care ultrasonography of femoral vessels is a well-established emergency physician technique for ruling out deep vein thrombosis and guiding femoral vessel catheterization. We present the first report of a pediatric emergency physician diagnosing a traumatic femoral artery thrombus using point-of-care ultrasonography.

BACKGROUND: Short (or small) saphenous vein (SSV) varices occur as a result of an incompetent sapheno-popliteal junction, where the SSV joins the popliteal vein, resulting in reflux in the SSV; they account for about 15% of varicose veins. Untreated varicose veins may sometimes lead to ulceration of the leg, which is difficult to manage. Traditionally, treatment was restricted to surgery or conservative management. Since the 1990s, however, a number of minimally invasive techniques have been developed; these do not normally require a general anaesthetic, are day-case procedures with a quicker return to normal activities and avoid the risk of wound infection which may occur following surgery...

BACKGROUND: Thrombolytic therapy is effective in selected patients with deep vein thrombosis (DVT). Therefore, identification of a marker that reflects the age of thrombus is of particular concern. This pilot study aimed to identify a marker that reflects the time after onset in human aspirated DVT. METHODS: We histologically and immunohistochemically analyzed 16 aspirated thrombi. The times from onset to aspiration ranged from 5 to 60 days (median of 13 days)...

Background Despite guideline-compliant prophylaxis, an increased rate of deep venous thrombosis (DVT) formation has been reported following autologous versus implant-based breast reconstruction. We hypothesized that tight abdominal fascia closure might decrease lower extremity venous return and promote venous stasis. Methods An observational crossover study of patients who underwent autologous breast reconstruction using transverse rectus abdominis musculocutaneous/deep inferior epigastric artery perforator flaps was conducted...

BACKGROUND: Recent anatomical findings have suggested that facial fat distribution is complex and changes with age. Here, we developed a grafting technique based on the physiological distribution and volume changes of facial fat compartments to achieve a youthful and natural-looking face. METHODS: Forty cadaveric hemifaces were used for the dissection of fat compartments and neurovascular structures in the mid-face area. Seventy-eight patients were treated for cheek atrophy using our targeted restoration of mid-face fat compartment volume...

REVIEW
Helia Robert-Ebadi, Marc Righini
Isolated distal deep vein thrombosis (DVT), also known as calf DVT, represents up to 50% of all lower limb DVT in ultrasound series and is therefore a frequent medical condition. Unlike proximal DVT and pulmonary embolism (PE), which have been extensively studied and for which management is well standardized, much less is known on the optimal management of isolated calf DVT. Recent data arising from registries and non-randomized studies suggest that most distal DVTs do not extend to the proximal veins and have an uneventful follow-up when left untreated...

In 2005, a 48-year-old man with a spinal cord injury had an inferior vena cava filter placed for recurrent deep vein thrombosis and pulmonary embolism. He was referred for filter retrieval after a computed tomography scan demonstrated caval stenosis and 2 fractured filter arms, 1 in a pulmonary artery and 1 penetrating into the retroperitoneum and impinging on the aorta. During retrieval, 1 arm was inadvertently advanced into the aorta, and embolization of the arm occurred to the left profunda femoris artery...
