Successful Coil Embolization Treatment of a Large Arterioportal Fistula: A Rare Cause of Mesenteric Ischemia.

Superior mesenteric arteriovenous fistulae (SMAVF) are a rare complication from trauma or iatrogenic surgical intervention. There are less than 50 cases reported in the literature and no clear guidelines as to the best practices for diagnosis and treatment. SMAVF are often asymptomatic but can present with nonspecific abdominal symptoms ranging from nausea and vomiting to gastrointestinal bleeding and mesenteric ischemia.

Uremic Leontiasis Ossea in a Patient With End-Stage Renal Disease in Hemodialysis.

Uremic leontiasis ossea is a rare condition, reported in patients with severe renal disease. Patients present with progressive enlargement of facial bones - in particular, the maxillary and mandibular bones. Rarity of this condition leaves clinicians puzzled on initial evaluation and management.

Characterization of Pulmonary Emboli in Total Joint Arthroplasty Patients Compared to General Medical Patients.

Pulmonary emboli (PEs) occur in medical and postoperative total joint arthroplasty (TJA) patients. These are different patient populations, yet both undergo identical diagnosis and treatment regardless of PEs size and quantity. To date, there has been no analysis of the location, size, and quantity of emboli that occur postoperatively in TJA compared with general medical patients.

Pulmonary Findings on Computed Tomography in Asymptomatic Total Joint Arthroplasty Patients.

An increase in the diagnosis of pulmonary embolus (PE) in the early postoperative period has been attributed to the use of multidetector 64-slice computed tomographic (CT) scans. It was suspected that this finding was the result of marrow or fat emboli that are commonly associated with arthroplasty rather than a true venous thromboembolic phenomenon. The purpose of this study was to determine the baseline pulmonary findings in asymptomatic patients after total joint arthroplasty (TJA).

Water as a contrast medium: a re-evaluation using the multidetector-row computed tomography.

Water as an intraluminal negative contrast medium produces improved image quality with reduced artefact. However, rapid absorption of oral water in the bowel relative to speed and timing of image capturing has limited its clinical application. These findings predate advances in multidetector-row computed tomography (CT).

Novel angle measurements for assessment of shoulder location using the scapular y radiograph.

Shoulder dislocation is an injury with potential long-term consequences that requires prompt diagnosis and treatment. Patient positioning and imperfect radiographic views may result in discomfort, added examination time, and problematic diagnosis. The scapular Y radiograph has been shown to be useful in diagnosing shoulder dislocation but is not considered sufficient in isolation.

The MR dimple sign in irreducible posterolateral knee dislocations.

While posterolateral knee dislocation is a rare entity, its identification has important implications. The invagination of skin seen in posterolateral knee dislocations is referred to as the "dimple sign" on physical exam. We report a case where the "dimple sign" was also demonstrated on magnetic resonance imaging.

Observational study on intrathecal and peridural changes after routine spinal and epidural anesthesia in patients undergoing total joint arthroplasty.

Epidural bleeding from spinal anesthetics or epidural catheter placement is concerning, especially when anticoagulants are used. Little is known of the natural changes that occur subdurally or epidurally after each of these procedures. To describe the natural history and occurrence of bleeding that may result from these anesthetics with anticoagulants, we studied 16 joint arthroplasty patients who underwent spinal magnetic resonance imaging postoperatively.

The use of polyacrylamide gel in soft-tissue augmentation: an experimental assessment.

Background: An increasing number of soft-tissue filler substances that lack experimental and clinical data have been introduced into plastic surgery practice outside the United States. One of these substances is polyacrylamide gel. It contains 2.
