Comparison of Double-Freeze versus Modified Triple-Freeze Pulmonary Cryoablation and Hemorrhage Volume Using Different Probe Sizes in an In Vivo Porcine Lung.

Purpose: To determine size of ablation zone and pulmonary hemorrhage in double-freeze (DF) vs modified triple-freeze (mTF) cryoablation protocols with different probe sizes in porcine lung.

Materials And Methods: In 10 healthy adult pigs, 20 pulmonary cryoablations were performed using either a 2.4-mm or a 1.

Inferior Vena Cava Filters: When to Place and When to Remove.

Pulmonary embolism (PE) is a common and feared result of deep vein thrombosis. While anticoagulation is the mainstay of management, interruption of flow of thrombus from leg veins to the pulmonary circulation is frequently desired either in lieu of or in addition to anticoagulation. Inferior vena cava filters have become frequently used to prevent PE despite a paucity of evidence for efficacy and increasing concerns about the long-term complications of indwelling filters.

Removal of Caval and Right Atrial Thrombi and Masses Using the AngioVac Device: Initial Operative Experience.

Purpose: To describe initial single-center experience with a thrombectomy device in managing right atrial and caval thrombi, tumors, and vegetations.

Materials And Methods: A retrospective analysis of AngioVac thrombectomy performed in 16 patients (mean age 53 y ± 13; 8 men, 8 women) between August 2013 and August 2015 was performed. Indications included right atrial mass/thrombus (6/16; 37.

Early Experience with AngioVac Aspiration in the Pulmonary Arteries.

Five consecutive cases in which the AngioVac aspiration cannula was used for the management of pulmonary embolism (PE) were retrospectively reviewed. Four cases (80%) presented with massive PE, and two (40%) were technically successful (reduction in Miller index ≥ 5). Four patients (80%) died at a mean of 7.

Evaluating patency rates of an ultralow-porosity expanded polytetrafluoroethylene covered stent in the treatment of venous stenosis in arteriovenous dialysis circuits.

Purpose: To evaluate the efficacy of an ultralow-porosity expanded polytetrafluoroethylene (ePTFE) covered stent in the treatment of autogenous arteriovenous fistula (AVF) and prosthetic arteriovenous graft (AVG) venous outflow stenoses.

Materials And Methods: Clinical and angiographic outcomes of 20 consecutive patients with arteriovenous dialysis circuits treated with the endoprosthesis were reviewed following institutional review board approval. Patients were followed routinely at 2 months and 6 months after stent placement, or earlier if clinically warranted.

Knowledge management and process monitoring of pharmaceutical processes in the quality by design paradigm.

Pharmaceutical processes are complex and highly variable in nature. The complexity and variability associated with these processes result in inconsistent and sometimes unpredictable process outcomes. To deal with the complexity and understand the causes of variability in these processes, in-depth knowledge and thorough understanding of the process and the various factors affecting the process performance become critical.

Uteroenteric fistula resulting from fibroid expulsion after uterine fibroid embolization: case report and review of the literature.

A 44-year-old woman underwent uncomplicated uterine fibroid embolization (UFE) for menstrual and bulk-related symptoms in an enlarged, myomatous uterus. After surgery, she spontaneously sloughed a large mass of fibroids that arrested in the cervical canal during passage. Four days after gynecological extraction, she developed copious vaginal discharge that contained enteric contents.

Developing a radiology-based teaching approach for gross anatomy in the digital era.

Rationale And Objectives: The purpose of this study was to assess the implementation of a digital anatomy lecture series based largely on annotated, radiographic images and the utility of the Radiological Society of North America-developed Medical Imaging Resource Center (MIRC) for providing an online educational resource.

Materials And Methods: A series of digital teaching images were collected and organized to correspond to lecture and dissection topics. MIRC was used to provide the images in a Web-based educational format for incorporation into anatomy lectures and as a review resource.

Intraoperative parathyroid hormone assay in patients with primary hyperparathyroidism and double adenoma.

Objective: To determine the utility of parathyroid hormone (PTH) monitoring for double adenomas (DAs).

Design: Retrospective chart review.

Setting: Tertiary referral center.

Regression of cerebral calcifications after endovascular treatment in a case of vein of Galen arteriovenous malformation.

The authors present the case of an infant harboring a vein of Galen arteriovenous malformation with conspicuous cerebral calcifications that progressively regressed after staged endovascular obliteration of the lesion. The role of venous hypertension and hydrocephalus secondary to the arteriovenous shunt are discussed to explain the formation and regression of the cerebral calcifications.

Two thousand Blalock-Taussig shunts: a six-decade experience.

Background: The Blalock-Taussig shunt (BTS) remains valuable for palliation of congenital heart disease, but its role has evolved. We reviewed our total institutional experience with BTS to examine changes in its use and outcomes.

Methods: A retrospective review was performed of all patients undergoing BTS at our institution from November 1944 to May 2006.
