REVIEW
Richard J Lin, David L Green, Gunjan L Shah
Patients with primary or metastatic brain tumors are at increased risk of developing venous thromboses. However, the potential benefit of therapeutic anticoagulation in these patients must be weighed against the deadly complication of intracranial hemorrhage. In this review, we summarize available evidence and recent studies of intracranial bleeding risks in primary and metastatic tumors and the impact of therapeutic anticoagulation. We find that for the majority of primary and treated metastatic brain tumors, the risk of spontaneous bleeding is acceptable and not further increased by careful therapeutic anticoagulation with low molecular weight heparin or direct oral anticoagulants, although thrombocytopenia (platelet count less than 50,000/μL) and other coagulopathies are relative contraindications...

OBJECTIVE To describe our en-bloc technique of retroperitoneal lymph node dissection (RPLND) during retroperitoneal laparoscopic radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UTUC) and evaluate perioperative outcomes. METHODS From 2002 to 2015, 114 patients with UTUC located at the pelvis and/or upper or middle ureter underwent retroperitoneal laparoscopic RNU at two institutions. Performance of RPLND began in February 2009. The template of RPLND included the renal hilar and para-aortic lymph nodes (left side) and the renal hilar, paracaval, retrocaval, and intra-aortocaval lymph nodes (right side)...

REVIEW
John Andrew Kaufman
The inferior vena cava filter clinical environment is notable for the degree of controversy, uncertainty, and fear associated with these devices by both physicians and the public. This article reviews some of the more important current issues with these devices as well as emerging and future trends.

Orthotopic aortic transplantation using the sleeve technique reduces injury to the aorta with failure rate of only 10-20%. The time to anastomose the aorta in mice using the sleeve method was short and easy averaging 20 min, permitting studies of iso/allo grafts. The following article describes the aortic transplantation procedure used in our laboratory. The mice were anesthetized with a mixture of 1.5% volume isoflurane and 100% oxygen through a face mask. At this point, the segment of the aorta between the renal arteries and its bifurcation was separated from the vena cava, freely prepared and clampedat the proximal and distal segments with a single silk suture...

Inferior vena cava (IVC) interruption is a rare condition that might pose difficulties during typical flutter ablation. When azygos vein continuation is present ablation via the femoral route could be performed. In the absence of azygos vein continuation, typical atrial flutter ablation via a superior approach from the SVC is feasible.

Objective The admission glucose level is a predictor of mortality even in patients with acute pulmonary embolism (APE). However, whether or not the admission glucose level is associated with the severity of APE itself or the underlying disease of APE is unclear. Methods This study was a retrospective observational study. A pulmonary artery (PA) catheter was used to accurately evaluate the severity of APE. The percentage changes in the mean PA pressure (PAPm) upon placement and removal of the inferior vena cava filter (IVCF) were evaluated...

A 62-year-old female with a history of anal gland adenocarcinoma presents with metastatic disease to the kidney with renal vein tumor thrombus extending into the inferior vena cava (IVC). Metastatic disease to the kidney with renal vein tumor thrombus is extremely rare with only several cases described in the literature. We present the first reported case of metastatic anal gland adenocarcinoma to the kidney with renal vein tumor thrombus.

Early stage acute kidney injury (AKI) is an independent risk factor for an increase in mortality. Accurate assessment of volume status is a major challenge during the early stages of acute renal injury. Determining volume status based on the history and physical exam lacks accuracy. Urine sodium and free excretion of sodium (FENa) provide objective evidence of intravascular volume status when interpreted carefully and is helpful to delineate prerenal from intrinsic renal failure. In recent years point of care ultrasound has been used to assess volume status...

A 56-year-old man with episodic abdominal pain was evaluated for acute left-side abdominal pain. CT scans showed an alternating location of the liver. This phenomenon, in which the liver is freely displaced along the transverse axis around the inferior vena cava, is called 'wandering liver'.

Postoperative bile leakage (BL) is a major complication of hepatic alveolar echinococcosis (HAE). The purpose of this study was to identify the risk factors for BL and to establish a simple scoring system for predicting BL.A total of 152 patients with HAE were included in the study between May 2004 and December 2016. The patient's baseline data, laboratory blood tests, imaging features, and surgical management were collected. Univariate and multivariate analyses were used to screen for factors to predict BL...

RATIONALE: Primary leiomyosarcoma (LMS) of the vein is a rare tumor that arises from the smooth muscle cells of the vessel wall and has an extremely poor prognosis. This tumor can occur in vessels such as the inferior vena cava, great saphenous vein, femoral vein, iliac vein, popliteal vein, and renal vein; the inferior vena cava is the most common site. LMS of the femoral vein can result in edema and pain in the lower extremity; therefore, it is not easy to be differentiated from deep vein thrombosis (DVT)...

BACKGROUND: Acute heart failure (AHF) is one of the leading causes of admission to emergency department (ED); severe hypoxemic AHF may be treated with noninvasive ventilation (NIV). Despite the demonstrated clinical efficacy of NIV in relieving symptoms of AHF, less is known about the hyperacute effects of bilevel positive airway pressure (BiPAP) ventilation on hemodynamics of patients admitted to ED for AHF. We therefore aimed to assess the effect of BiPAP ventilation on principal hemodynamic, respiratory, pulse oximetry, and microcirculation indexes in patients admitted to ED for AHF, needing NIV...

BACKGROUND AND AIMS: The purpose of this study is to report our 20-year experience with the surgical management of renal cell carcinoma extending into the inferior vena cava using a novel classification system. MATERIALS AND METHODS: We retrospectively reviewed the data of 103 patients (69 males, 34 females, mean age: 52.9 ± 12.6 years) with renal cell carcinoma involving the venous system treated between 1993 and 2014. The inferior vena cava tumor thrombus was classified into five levels: 0 (renal vein, n = 12), 1 (infrahepatic, n = 33), 2a (low retrohepatic, n = 26), 2b (high retrohepatic, n = 19), and 3 (supradiaphragmatic, n = 13)...

We herein report a case of a retroperitoneal tumor of unknown origin that was diagnosed as a seminoma after tumor biopsy and was successfully treated with chemotherapy containing bleomycin, etoposide, and cisplatin(BEP). A 47-year old man visited our hospital with left abdominal pain. An endoscopic examination revealed an ulcer lesion on the third part of the duodenum. Abdominal CT scan revealed a retroperitoneal tumor invading the abdominal aorta with the tumor thrombus in the inferior vena cava(IVC). An endoscopic biopsy could not identify the tumor's origin because of the negative staining of various surface markers on immunohistochemistry...

OBJECTIVES: Rat models of renal transplant are used to investigate immunologic processes and responses to therapeutic agents before their translation into routine clinical practice. In this study, we have described details of rat surgical anatomy and our experiences with the microvascular surgical technique relevant to renal transplant by employing donor inferior vena cava and aortic conduits. MATERIALS AND METHODS: For this study, 175 rats (151 Lewis and 24 Fisher) were used to establish the Fisher-Lewis rat model of chronic allograft injury at our institution...

Background  Nutcracker phenomenon (NCP) can occur due to various anatomical anomalies. Anterior and posterior NCP are defined in the literature. Posterior NCP combined with left atrial isomerism is a rare condition. Case description  We present a rare case of an asymptomatic posterior NCP involving the azygos vein in a patient with a complex cardiovascular pathology with left atrial isomerism, left ventricular outflow tract obstruction, interrupted inferior vena cava, and azygos continuation. Conclusion  Detection of the NCP especially involving such a rare anatomical anomaly as an azygos continuation has a crucial importance for diagnostic and surgical procedures...
