There is a paucity of robust clinical trial data to guide the treatment of acute pulmonary embolism (PE) thus the clinical guidelines rely heavily on expert opinion. Pulmonary Embolism Response Teams (PERT) have been developed to streamline the care of patients with acute PE. We conducted a survey among 100 experts in the field of PE during the second annual meeting of the PERT Consortium. Respondents were queried with respect to their demographic information, clinical practice questions and clinical vignettes...

BACKGROUND: Inferior vena cava (IVC) ultrasonography has been used for the diagnosis and prognosis of acute heart failure (HF). Its usefulness in chronic HF is less known. HYPOTHESIS: IVC ultrasonography is a useful tool in the care of patients with chronic HF. METHODS: For this prospective cohort study, 95 patients with chronic HF were included consecutively as they attended scheduled medical visits. Ultrasound was done with a 5-MHz convex probe device, calculating IVC collapse index (IVCCI)...

Introduction: Firearm-related injuries account for 20% of all injury-related deaths and are responsible for 105,000 injuries annually. The occurrence of bullet emboli to the heart is exceedingly rare. Given the rarity of emboli, controversy exists over management. The primary endpoint of this study is to establish a management algorithm for venous bullet emboli to the heart. Materials and methods: A literature search was performed using PubMed and Google Scholar with the following search terms: cardiac bullet embolus, cardiac missile embolus, and bullet embolus...

OBJECTIVE: Inferior vena cava filters (IVCFs) are indicated for therapeutic and prophylactic treatment of venous thromboembolism in patients where anti-coagulation has failed or is contraindicated. Retrievable IVCFs are not always retrieved despite clinical recommendations. The purpose of this review is to compare results in the literature regarding interventions to improve IVCF retrieval rates. METHODS: Articles were identified via the search terms "vena cava filters" and "inferior vena cava filters" in conjunction with "retrieval...

Curative resection is necessary to survival in pancreatic cancer, however after surgery, pathologic examination sometimes diagnoses the remains of cancer at the resected stump. Therefore, it is necessary to evaluate the stump by intraoperative rapid pathological examination. 5-aminolevulinic acid(5-ALA)is an endogenous natural amino acid and precursor of the heme pathway. 5-ALA is metabolized and accumulated as protoporphyrin IX(Pp IX)that is photosensitive substance. 5-ALA mediated photodynamic diagnosis(PDD)(ALA-PDD)has high diagnostic ability...

BACKGROUND: A permanently indwelling filter in the inferior vena cava (IVC) may induce caval thrombosis, which could develop and evolve from an acute to a chronic phase. The differential diagnosis of acute and chronic thromboses determines the treatment strategy. The role of computed tomography (CT) in diagnosing acute and chronic intra-filter and IVC thromboses has not been well established. This retrospective study summarizes the CT signs that indicate acute and chronic phases of intra-filter and IVC thromboses...

The aim of this study was to investigate the clinical benefit of presurgical therapy with pazopanib in renal cell carcinoma (RCC) patients with a tumor thrombus extending to a high level in the vena cava. A retrospective review was performed for seven consecutive patients with RCC and tumor thrombus involving the vena cava above the hepatic vein (level 3-4, Mayo Clinic classification) treated with pazopanib without initial cytoreductive nephrectomy at our institution. The effect of pazopanib was assessed in terms of the primary site response, thrombus diameter, and height (before and after treatment) on computed tomography or MRI...

Wilms' tumor (WT) is the most common pediatric renal tumor that often spreads to inferior vena cava and sometimes up to right atrium (RA). We describe successful management of 3-year-old child diagnosed with WT having extension up to RA. He was operated under cardiopulmonary bypass and extubated on postoperative day 2 and discharged. Perioperative anesthesia concerns were shock from dynamic tricuspid valve obstruction, intraoperative massive blood loss, and a higher risk of pulmonary thromboembolism during tumor manipulation...

Venous compression syndromes are caused by extrinsic venous compression of anatomical structures, such as the adjacent arteries and bones. Chronic venous compression and pulsative vibratory arterial pressure accelerate the development of deep vein thrombosis. Herein, we report the first case of double venous compressions due to a duplicated inferior vena cava-induced right-sided common iliac vein thrombosis. The thrombus was induced by left-sided inferior vena cava entrapment and right-sided common iliac vein compression, resembling nutcracker syndrome and May-Thurner syndrome, respectively...

Uterus transplantation may become the surgical therapeutic modality of choice for uterine factor infertility. However, this procedure still faces technical, therapeutic, and immunologic challenges that limit its success and clinical application. Experimental studies are therefore still needed to address various challenges in the field of uterus transplantation. Among various laboratory animals, small animals are ideal models for the purpose of experimental uterus transplant. However, clinical success in small animal models is not generalizable to clinical application and treatment for uterine factor infertility in humans...

PURPOSE: To assess whether the ultrasonographic measurement of the inferior vena cava (IVC) diameter in postpartum women is a useful parameter in evaluating the actual blood loss during delivery due to massive postpartum hemorrhage. MATERIALS AND METHODS: In postpartum women with blood loss ≥ 500 g, abdominal ultrasonography was performed 1 hour after delivery. The IVC diameter was measured during inspiration (IVCi) and expiration (IVCe). The maternal heart rate, blood pressure, and shock index (heart rate/systolic blood pressure) were also measured...

The aim of this study was to evaluate the effect of patient characteristics on the contrast agent dosage that is required to reach effective enhancement of the inferior vena cava (IVC) on computed tomography venographs (CTV).This retrospective study included 50 patients who underwent CTV at 80 kVp. The contrast injection protocol (iodine 600 mg/kg) was tailored to their body weight. We calculated the required contrast agent volume (CAVmean-IVC) to reach the mean enhancement of IVC. We performed univariate and multivariate linear regression analyses between the sex, age, body weight (BW), lean body weight (LBW), body surface area (BSA), height (HT), estimated glomerular filtration rate (eGFR), and CAVmean-IVC...

Vascular laparoscopic injuries are rare (0.2/1000), however, they are associated with 6-13% morbidity and mortality. Commonest sites for catastrophic haemorrhage are the right iliac vessels, inferior vena cava and less commonly the abdominal aorta. The injuries commonly occur at entry using a Veress needle or insertion of trocars. These risks are inherent to all laparoscopic surgery. A systematic approach for managing these includes prompt recognition, communication within the operative team, immediate resuscitation and specific operative strategies for the control of vascular haemorrhage based on the location and severity of the injury...

BACKGROUND: Diagnosis and management of patients presenting with acute dyspnea is one of the major challenges for physicians in emergency department (ED). A correct diagnosis is frequently delayed and difficult to ascertain, and clinical uncertainty is common, explaining the need for rapid diagnosis and a management plan. The primary aim of our study is to assess a diagnostic strategy using multiorgan point of care ultrasonography (USG) to differentiate patients presenting with acute dyspnea to ED into different diagnostic categories for timely management in a resource-limited setting...

The purpose of this study was to assess the smallest possible body sizes of patients in whom the Cleveland Clinic continuous-flow total artificial heart for adult (CFTAH) and pediatric configurations (P-CFTAH) can fit. One of the most critical dimensions is the vertebra-to-sternum distance at the junction of the right atrium to the inferior vena cava (V-S distance). Our previous CFTAH anatomical fitting study suggested that the CFTAH would fit patients of V-S distance ≥ 7.5 cm and the P-CFTAH of V-S distance ≥ 5...
