Evacuation of hematomas using liposuction technology: Technique and literature review

Established nonexpanding hematomas can be successfully treated with minimal morbidity using standard liposucstion techniques at the bedside or in an outpatient setting under local anesthesia. The authors presents a series of eight patients and discuss current concepts of dealing with this common and distressing surgical complication.     

New universal precaution aspiration tray

A new tray has been designed for use during procedures involving needles and other sharp objects. The tray includes a foam adhesive pad, marked into 10 sections, into which the sharp objects can be placed point first. After the procedure, the objects can be safely withdrawn by their handles and then discarded. The tray has been used in more than 250 procedures.     

Radiologically guided balloon dilation of gastrointestinal strictures. Part I. Technique and factors influencing procedural success

Radiologically guided balloon catheters were used to dilate 94 gastrointestinal strictures in 92 patients over a 6-year period. Fifty strictures were esophageal and 44 nonesophageal (22 gastroenterostomies, 11 antral-pyloric strictures, four colorectal strictures, four enteroenterostomies, and three miscellaneous strictures). Factors influencing the success of stricture intubation included patient age, stricture location (esophageal vs. nonesophageal and proximal vs. distal esophageal), and association with a surgical anastomosis. Malignancy was associated with greater postdilation irregularity and a smaller increase in stricture diameter, as measured radiographically. Procedural failures occurred in 8% of cases (2% of esophageal and 30% of nonesophageal lesions). Two small, asymptomatic mucosal tears were seen after dilation (one esophageal and one colonic); no other procedural complications occurred. Following successful dilation, 16 patients (17%; six with esophageal and ten with non-esophageal strictures) had recurrence of symptoms during short-term (30-day) follow-up.     

Tongue and oropharynx: findings on MR imaging

Ten healthy subjects and 44 patients with diseases of the tongue or oropharynx were studied with magnetic resonance (MR) imaging. Axial, coronal, and sagittal images with a thickness of 4 mm were obtained with a pixel size of 0.75 X 0.75 mm on a 256 matrix. Nineteen of the patients underwent computed tomography (CT). Nine of those patients later had surgery, and the specimens were obtained for organ sectioning. These three studies as well as clinical history and physical examination findings were correlated. MR imaging was equal to or better than CT in those patients having both examinations. However, neither CT nor MR allowed recognition of histologic features or detection of microscopic spread of disease. Direct coronal and sagittal imaging planes on MR imaging allowed visualization of intrinsic tongue musculature, not possible with CT; this was important in recognizing subtle tumor extension. For these reasons, MR is the imaging method of choice for studying diseases of the tongue and oropharynx.     

AIDS awareness in the conduct of radiologic procedures: guidelines to safe practice

The epidemic of the acquired immunodeficiency syndrome (AIDS) has affected all geographic regions of the United States. Indeed, it is likely that a majority of U.S. hospitals have cared for patients who are infected with the human immunodeficiency virus (HIV), the virus that causes AIDS. More than 46,000 individuals with HIV infection have fulfilled the strict diagnostic criteria for AIDS (1). All of these patients with AIDS have been seriously ill and have been hospitalized, often multiple times and for prolonged periods. Another, larger group patients with HIV infection has had another form of the disease, the so-called AIDS-related complex. Many of these patients have also spent time in hospitals. An even larger group of individuals has been infected with HIV but has remained asymptomatic to date. Some of these persons have been admitted to hospitals or have received outpatient diagnostic procedures for intercurrent medical or dental complaints that were unrelated to their asymptomatic HIV infection. At the time of their medical evaluation, some of these asymptomatic individuals were known to have a positive HIV antibody test. It is likely, however, that the serologic status of the majority of asymptomatically infected patients was unknown. Thus, by now a very large number of health-care personnel in the United States, including diagnostic radiology staff, have assisted in the care of HIV-infected patients.
