Inferior cava vein guidelines

Riten Kumar, Bryce A Kerlin
Abdominal venous thrombosis is a rare form of venous thromboembolic disease in children. While mortality rates are low, a significant proportion of affected children may suffer long-term morbidity. Additionally, given the infrequency of these thrombi, there is lack of stringent research data and evidence-based treatment guidelines. Nonetheless, pediatric hematologists and other subspecialists are likely to encounter these problems in practice. This review is therefore intended to provide a useful guide on the clinical diagnosis and management of children with these rare forms of venous thromboembolic disease...

AIM: to investigate the short-term outcomes and risk factors indicating postoperative death of patients with lesions adjacent to the hepatocaval confluence. METHODS: We retrospectively analyzed 54 consecutive patients who underwent hepatectomy combined with inferior vena cava (IVC) and/or hepatic vein reconstruction (HVR) from January 2012 to January 2016 at our liver surgery center. The patients were divided into 5 groups according to the range of IVC and hepatic vein involvement...

For identification of potentially surgically curable primary aldosteronism, guidelines recommend use of adrenal vein sampling (AVS) that requires selective catheterization of both adrenal veins as verified by using the cortisol-derived selectivity index. Unfortunately, bilaterally selective studies are not obtained under unstimulated conditions in a proportion of the cases ranging between 15% and 50% depending on the cutoff used. We therefore investigated whether 17-α-hydroxyprogesterone and androstenedione, which showed a higher step-up between adrenal vein and inferior vena cava blood than cortisol, can ascertain selectivity when cortisol failed to do so...

INTRODUCTION: Intravenous leiomyomatosis (IVL) is a rare smooth muscle tumor, usually found in women with tumors of the reproductive organs, such as uterus myomatosous. Surgically, this case belies the call for sternotomy and two-stage surgery in caval IVL extending to the right atrium: we suggest one-stage median laparotomy as a minimal procedure with maximal benefit. PRESENTATION OF CASE: We present the case of a 60-year-old postmenopausal woman with suspected intravenous leiomyomatosis of the right internal iliac vein...

INTRODUCTION: Inferior vena cava filters are used to prevent embolization of a lower extremity deep vein thrombosis when the risk of pulmonary embolism is thought to be high. However, evidence is lacking for their benefit and guidelines differ on the recommended indications for filter insertion. The study aim was to determine the reasons for inferior vena cava filter placement and subsequent complication rate. MATERIALS AND METHODS: A retrospective cohort of patients receiving inferior vena cava filters in Edmonton, Alberta, Canada from 2007 to 2011...

Venous thromboembolism (VTE), which constitutes pulmonary embolism and deep vein thrombosis, is a common disorder associated with significant morbidity and mortality. Landmark trials have shown that direct oral anticoagulants (DOACs) are as effective as conventional anticoagulation with vitamin K antagonists (VKA) in prevention of VTE recurrence and associated with less bleeding. This has paved the way for the recently published guidelines to change their recommendations in favor of DOACs in acute and long-term treatment of VTE in patients without cancer...

OBJECTIVE: Adrenal venous sampling (AVS) is recommended by clinical guidelines to distinguish surgically curable types of primary aldosteronism, but remains widespread underused mainly due to difficulty in successful sampling. When considering that the right adrenal vein is angled caudally, AVS through upper extremity approach may be more appropriate. The purpose of this study was to establish the technique ofAVS via median cubital vein (MCV), and evaluate its safety and feasibility. DESIGN AND METHOD: From January 2012 to June 2015, 194 consecutive patients diagnosed as primary aldosteronism underwent AVS via MCV at the Fuwai Hospital...

INTRODUCTION: The Fontan procedure (FP) has become the standard operation for patients with single ventricle physiology. However, a long period of elevated systemic venous pressure and low cardiac output after the procedure result in chronic inflammation and liver cirrhosis, which may eventually lead to the occurrence of hepatocellular carcinoma (HCC). CLINICAL FINDINGS: We described the case of a 16-year-old female who developed HCC after the FP. At 21 months, the patient received a lateral tunnel FP, and 14 years later, she began complaining of abdominal distension, telangiectasia, and fatigue...

Thrombotic occlusion of central venous catheters (CVCs) is a common problem in newborns. No guideline systematically addresses the diagnosis, management, and prevention of this complication. The objective of this review is to establish evidence-based guidance for the management of CVC thrombosis. A comprehensive literature search was conducted from 1948 to 2012. Twenty-six articles fulfilling four criteria - humans, neonates aged less than 28 days, CVC insertion, and English language - were included for analysis...

BACKGROUND: Acute pancreatitis is an acute inflammatory process of the pancreas that can trigger a systemic inflammatory response. Pulmonary embolism refers to obstruction of the pulmonary artery or one of its branches by material (usually a thrombus) that originated elsewhere in the body. Extensive lower limb deep vein thrombosis with pulmonary embolism is a rare complication of acute pancreatitis that has been described in a few case reports. Deep vein thrombosis and hypercoagulable states in pancreatitis are thought to be due to release of pancreatic proteolytic enzymes from a cyst that is connected to the pancreatic duct and penetrates into a vessel...

Cancer is one the most prevalent risk factors in patients diagnosed with deep vein thrombosis or pulmonary embolism. Patients with cancer and venous thromboembolism have a higher risk of mortality when compared to patients with cancer without venous thromboembolism and a higher risk of recurrent thrombosis when compared with patients with venous thromboembolism without cancer. This increased risk of recurrence is not only observed after anticoagulant treatment is stopped, but also during anticoagulant treatment...

Renal cell carcinoma accounts for 2%-3% of all visceral malignancies. Preoperative imaging can provide important staging and anatomic information to guide treatment decisions. Size of the primary tumor and degree of local invasion, such as involvement of perinephric fat or renal sinus fat, and tumor thrombus in renal veins and inferior vena cava are important detriments to local staging of primary tumor. Both kidneys are assessed for presence of other synchronous lesions. The ACR Appropriateness Criteria(®) are evidence-based guidelines for specific clinical conditions that are reviewed every three years by a multidisciplinary expert panel...

Renal cell carcinoma (RCC) accounts for 85-90% of kidney cancers, which in turn account for 2-3% of all malignant tumors in adults. Xp11.2 translocation/TFE3 gene fusion RCC is currently classified as a distinct type of RCC. RCC is capable of invading the renal vein and inferior vena cava to form a tumor thrombus. The incidence of RCC with tumor thrombi within the renal vein or inferior vena cava is 7-10% in China. In the present case report, the patient underwent radical resection of the renal tumor and removal of the tumor thrombus, assisted by cardiopulmonary bypass, for the treatment of Xp11...

May-Thurner syndrome (MTS) is an anatomically variable condition resulting in compression of the left common iliac vein between the right common iliac artery and the underlying spine with subsequent development of a left deep vein thrombosis (DVT). Although this syndrome is rare, its true prevalence is likely underestimated. Mainly, clinical symptoms and signs include, but are not limited to, pain, swelling, venous stasis ulcers, skin pigmentation changes and post-thrombotic syndrome. Correct treatment is not well established and is based on clinical presentation...

Pulmonary vein isolation (PVI) is the cornerstone of current ablation techniques to eliminate atrial fibrillation (AF), with the greatest efficacy as a stand-alone procedure in patients with paroxysmal AF. Over the years, techniques for PVI have undergone a profound evolution, and current guidelines recommend PVI with confirmation of electrical isolation. Despite significant efforts, PV reconnection is still the rule in patients experiencing post-ablation arrhythmia recurrence. In recent years, use of general anesthesia with or without jet ventilation, open-irrigated ablation catheters, and steerable sheaths have been demonstrated to increase the safety and efficacy of PVI, reducing the rate of PV reconnection over follow-up...

A recent multicenter registry study of venous thromboembolism (VTE) patients in Japan demonstrated a high prevalence of inferior vena cava (IVC) filter placement. However, data regarding indications, applications, and outcomes of IVC filters in Japanese patients are quite limited. This study was an observational, single-center, retrospective cohort study of all consecutive patients with acute VTE treated between March 2006 and February 2014. Data extracted included patient demographics, indications, applications, and complications of IVC filters, as well as VTE recurrence and death...
