We report a case of exercise-induced spontaneous thrombosis of the left spermatic vein. The sonographic appearance mimicked an incarcerated left inguinal hernia by demonstrating a tubular, hypoechoic, noncompressible, cystic appearing inguinal mass with no flow evident on color Doppler imaging.
We conducted a prospective evaluation of the normal vermiform appendix in 203 patients. Conventional CT techniques were utilized with an 8 mm slice thickness and 10 mm slice interval. The normal appendix was definitely identified in 51% of the patients studied. Computed tomographic appearance of the normal appendix is demonstrated, and potential pitfalls are described.
Twenty consecutive patients requiring surgical procedures on a lower extremity received leg blocks using a modification of Labat's classic approach. A Doppler ultrasound pencil probe was used to identify the dominant arterial structure exiting the sciatic notch with the sciatic nerve. A block needle was inserted in the same orientation as the probe until paraesthesias were elicited; then 25 ml of local anesthetic was injected. Successful block was achieved in one or two attempts in 70% of the patients.
