OBJECTIVE. We sought to compare image quality, contrast enhancement, and radiation dose in patients undergoing ECG-triggered high-pitch helical CT or non-ECG-synchronized helical CT of the thoracoabdominal aorta. MATERIALS AND METHODS. We retrospectively assessed data from 101 consecutive patients (81 men, 20 women; mean age, 71 +/- 11 [SD] years) undergoing clinically indicated CT angiography (CTA) of the thoracoabdominal aorta on a dual-source scanner using either the ECG-triggered high-pitch helical mode (group 1, n = 52) or non-ECG-synchronized standard-pitch helical mode (group 2, n = 49) during the arterial phase. Two independent readers assessed image quality, noise, and contrast enhancement throughout the thoracoabdominal aorta. Scanner-reported dose-length product values were used to estimate effective dose values. RESULTS. Image quality at the root-proximal ascending level was higher in group 1 (mean +/- SD, 2.81 +/- 0.40) than in group 2 (1.22 +/- 0.47; p < 0.0001), with similar quality for both groups noted at other levels. Group 1 scans displayed higher image noise at all levels. The groups received a similar volume of contrast material (p = 0.77), and similar percentages of cases with acceptable contrast enhancement (> 250 HU) were noted in the two groups. The estimated radiation burden was significantly lower in group 1 (mean +/- SD, 5.4 +/- 1.8 mSv) than in group 2 (14.4 +/- 5.1 mSv; p < 0.0001). CONCLUSION. Imaging of the thoracoabdominal aorta with ECG-triggered high-pitch CTA provides higher quality images of the aortic root and ascending aorta with sufficient contrast enhancement and decreased estimated radiation dose compared with non- ECG-synchronized standard-pitch helical CT.

Physiology laboratory experience for high school students.

Recently, we were charged with providing a learning opportunity for high school students participating in the Upward Bound Regional Math and Science Program, a program designed to stimulate interest in mathematics and science for students from disadvantaged environments. Our challenge was to introduce students to the joys, excitement, and mystery of physiology and to stimulate their interest for future study. To this end, we developed a laboratory experience that examined basic physiological concepts in an animal model. This opportunity introduced students to how their bodies work and the importance of the use of animals in research. The students left the experience confident, motivated, and excited about learning.

STUDY DESIGN: A retrospective review was completed on 21 patients who had a "least invasive" (one or two level) microdecompression and uninstrumented single-segment lumbar fusion for spinal canal stenosis with degenerative spondylolisthesis. OBJECTIVE: To determine whether a "least invasive" approach to lumbar spinal canal stenosis and degenerative spondylolisthesis would yield acceptable results. SUMMARY OF BACKGROUND DATA: The prevailing surgical technique for symptomatic spinal canal stenosis with degenerative spondylolisthesis is a wide midline decompression and instrumented fusion. METHODS: On an average of 38 months postoperatively, 21 patients were personally assessed on four scores: 1) their overall satisfaction with the outcome of surgery, 2) an analog back and leg pain scale, 3) a functional evaluation scale, and 4) Ferguson (upshot) anterior-posterior lumbosacral and lateral flexion-extension radiographs. RESULTS: The overall satisfactory outcome on all four scales was 16 (76%) of 21. Twenty of twenty-one patients had relief of their claudicant leg pain; the overall fusion rate was 18 (86%) of 21. Two of three patients with a pseudarthrosis had a successful outcome on the patient-oriented outcome (1, 2, and 3) scales (excluding the radiograph scale), and one was a failure. One patient with a solid fusion was a failure because of continuing back pain. One patient with a solid fusion was a failure because of continuing leg pain. The overall satisfactory outcome on the nonradiographic scales was 18 of 21, for an 86% patient satisfaction rate. CONCLUSIONS: In this retrospective study, a "least invasive" surgical approach to lumbar degenerative spondylolisthesis with spinal canal stenosis causing claudicant leg pain produced acceptable results.

Robotic harvest of the rectus abdominis muscle: a preclinical investigation and case report.

In an attempt to decrease donor-site morbidity for rectus abdominis muscle harvest during free tissue transfer, we developed a technique of minimally invasive harvest. The da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA) was used in two cadavers for dissection and harvest of four rectus abdominis muscles. After the cadaver dissections were performed, the technique was used in a 30-year-old woman to harvest the left rectus abdominis muscle for free tissue transfer to a lower extremity defect. Four cadaver dissections for harvest of the rectus abdominis muscle using the da Vinci Surgical System were performed. In the cadavers and actual case, three ports (11 mm, 11 mm, and 15 mm) were used to access the abdominal cavity and perform the dissection. An additional 3 cm incision was used to remove the muscle from the abdominal cavity. The patient has not developed any surgical-site morbidity, including bulge or hernia in the 6 months postprocedure. Minimally invasive harvest of the rectus abdominis muscle is possible with the assistance of the da Vinci Surgical System. Potential benefits may include decreased surgical-site morbidity. Also, this may provide an approach to minimally invasive transperitoneal reconstruction.
