Intraoperative spinal cord monitoring during descending thoracic and thoracoabdominal aneurysm surgery.
Postoperative paraplegia is one of the most dreaded complications after descending thoracic and thoracoabdominal aneurysm surgery. In this study, intraoperative monitoring was applied during resection of descending thoracic and thoracoabdominal aneurysms to detect spinal cord ischemia and help prevent paraplegia. ⋯ The results demonstrate that compared with SSEP, MEP, especially myogenic MEP, is more sensitive and specific in detection of spinal cord ischemia, and that intraoperative monitoring can indeed help prevent paraplegia.

Stent grafts for the thoracic aorta: a new paradigm?
The treatment of thoracic aortic pathology is complicated by the morbidity of the surgical procedure, and the comorbidities encountered in an elderly population. Stent grafts have now been used for approximately 10 years for the treatment of thoracic aneurysmal disease, management of aortic dissections, intramural hematoma, and giant penetrating ulcers, and for traumatic aortic tears, with impressive early results. ⋯ Nevertheless, significant and even unique therapies have been enabled by stent graft technology for the treatment of the above-mentioned diseases. It is likely that, with more sophisticated technology and improved understanding of thoracic aortic pathology, stent graft use will expand, and its utility will be further clarified.

The appropriate surgical strategy for patients with an arch tear in acute type A dissection remains controversial. We retrospectively compared surgical results after hemiarch as compared with transverse aortic arch replacement in patients with an arch tear in acute type A dissection. ⋯ Hemiarch replacement for acute type A dissection demonstrated favorable early and late outcome. The extent of graft replacement influenced surgical mortality and morbidity. Whenever the intimal tear is located in the lesser curvature of the transverse arch, hemiarch replacement is recommended to improve overall operative mortality and morbidity.

Randomized Controlled Trial Clinical Trial
Development of a CD-ROM Internet Hybrid: a new thoracic surgery curriculum.
The TSDA Prerequisite Curriculum Committee has successfully developed the content for a didactic curriculum to be mastered by the residents before their matriculation in a thoracic surgical residency program. In addition the committee assembled an innovative electronic format consisting of a CD-ROM Internet Hybrid to teach this curricular material. By use of a serialized CD-ROM Internet Hybrid it is possible to store relatively dense high bandwidth portions of the curriculum including video and audio materials on the CD-ROM and yet allow constant updating and interaction of the other portions of the curriculum. ⋯ It is our anticipation that successful completion of this project will not only allow for the use of an innovative highly technical means of education for our residents but may in turn become broadly applicable to many other types of educational projects within thoracic surgery education. This may also be applicable to other types of educational projects in the postgraduate education industry and other venues as well. The conduct of a scientific study monitoring the impact of this curriculum project as well as the acceptance of the project by the resident is also relatively unique and will be scrutinized by numerous professional medical and educational groups.
