Multidetector computed tomography (MDCT) scanning technology has increased the ease with which pulmonary emboli (PE) are evaluated. Our aim was to determine whether the incidence and severity of postoperative PE have changed since adoption of multidetector computed tomography. ⋯ Chest CT scans are being performed more frequently on postoperative cancer patients and have resulted in an increased diagnosis of peripheral PE. The clinical significance of, and optimal treatment for, diagnosed subsegmental PE are incompletely defined.

Endovascular grafts have rapidly evolved as a minimally invasive treatment for a variety of acute and chronic disorders of the thoracic aorta. Application of this technology at a single center is reported. ⋯ Thoracic endovascular aortic repair represents an effective treatment for a variety of pathologic states. But the risk-benefit analysis for thoracic endovascular aortic repair should carefully consider the extent of disease, pathologic condition, and renal function.

Although a large proportion of patients with traumatic thoracic aortic injury die before undergoing definitive repair, those who survive still face ongoing risk of death and morbidity. Endovascular therapy may offer a minimally invasive alternative in the repair of the aortic injury. ⋯ Although patients who undergo endovascular repair of traumatic thoracic aortic transections typically have significant concomitant injuries, the procedure itself is well tolerated and can be performed rapidly with minimal blood loss and contrast administration. But close followup is necessary given the risk of late complications.

Some patients require major leg amputation after lower-extremity prosthetic bypass for graft occlusion or failure of wound healing, despite a patent graft. Amputation above or below the knee was hypothesized to increase susceptibility to prosthetic graft infection in the ipsilateral extremity. ⋯ Amputation increases risk of prosthetic graft infection, especially when performed early or after failed revascularization. Consideration should be given to partial or complete removal of a prosthetic graft above the level of the amputation under these conditions.

Venous thromboembolism (VTE) is reported to occur among 7% to 58% of trauma patients. Variability in VTE rates might reflect differences in case mix and quality of care, but also screening practices or data capture. We explored the variation in VTE rates across trauma centers to determine its use as a measure of the quality of patient care. ⋯ There was substantial variation in rates of VTE across trauma centers. There was no relationship between DVT and PE outlier status, which is counter to the understanding of the biologic relationship between the two. Lastly, the very low Intraclass correlation coefficient for PE compared with DVT suggests that to a large extent, practice variation has very little impact on PE rates. In light of these findings and concerns about patient ascertainment of DVT, VTE rates might not be a useful measure of quality of care.
