The availability of ultrasonography and computerized tomography has significantly improved diagnostic capability in the evaluation of splenic abscess. In addition, recent evidence has shown that percutaneous drainage of splenic abscess is a safe and efficacious approach to therapy and is indicated especially when patients are seriously ill, postoperative or when the risks of general anesthesia, surgical drainage or splenectomy are substantial. ⋯ Discussion of important features of this illness, as well as a comprehensive review of reported instances and guidelines related to percutaneous drainage of splenic abscess, are presented herein. A team approach, which uses the experience of imaging and surgical personnel, is invaluable in therapy when a splenic abscess is encountered.

Comparative StudyUse of the multiple uptake gated acquisition scan for the preoperative assessment of cardiac risk.
A retrospective study was undertaken at three hospitals of 196 patients who underwent an operative procedure as long as 60 days after radionuclide determination (multiple uptake gated acquisition scan [MUGA]) of left ventricular ejection fraction (LVEF). Cardiac related mortality rates were 2.2 per cent among patients in group 1, LVEF greater than or equal to 55 per cent; 5.4 per cent in group 2, LVEF 36 to 54 per cent, and 19.5 per cent in group 3, LVEF less than or equal to 35 per cent (p less than 0.005). Statistically significant correlation between MUGA-derived LVEF and cardiac related mortality was found in veteran patients undergoing noncardiac surgical procedures (both vascular and nonvascular). ⋯ A preoperative American Society of Anesthesiologists Physical Status Evaluation classification of IV or a preoperative pulmonary capillary wedge pressure of 20 centimeters of water or greater also predicted an increased risk of postoperative cardiac death. We advise preoperative MUGA scans for all patients in whom the results of preoperative history or physical examination suggest compromised ventricular function. We also advise pulmonary arterial catheter hemodynamic monitoring during the perioperative period for all patients with a preoperative MUGA-derived LVEF of less than or equal to 35 per cent.

A simple technique for redirection of malpositioned Broviac or Hickman catheters.
A simple angiographic technique for repositioning an aberrantly located Broviac or Hickman catheter tip is described. It is easy to perform and requires catheters and guide wires that are available in all angiography rooms. The technique is effective, and it has had no complications.
