To determine the results of simultaneous thoracic endovascular aortic repair (TEVAR) and endovascular aneurysm repair (EVAR). ⋯ Combined TEVAR and EVAR can be performed successfully with minimal morbidity and mortality. In particular, in this limited series of eight patients, there have been no occurrences of lower extremity paralysis or renal failure despite a high proportion of emergent cases. When anatomically feasible, simultaneous TEVAR and EVAR can be considered as a viable alternative to staged or hybrid repair.

Prior studies have reported improved clinical outcomes with higher surgeon volume, which is assumed to be a product of the surgeon's experience with the index operation. We hypothesized that composite surgeon volume is an important determinant of outcome. We tested this hypothesis by comparing the impact of operation-specific surgeon volume versus composite surgeon volume on surgical outcomes, using open abdominal aortic aneurysm (AAA) repair as the index operation. ⋯ The current study suggests that composite surgeon volume-not operation-specific volume-is a key determinant of in-hospital mortality for open AAA repair. This finding needs to be considered for future credentialing of surgeons.

The purpose of this report was to present short and midterm results of endovascular aortic aneurysm repair (EVAR) of infrarenal aortic aneurysms in octogenarians and nonagenarians. ⋯ EVAR in octogenarians and nonagenarians is associated with a significantly higher but still low perioperative mortality compared to younger patients. Midterm survival in octogenarians and nonagenarians, although significantly lower than in younger patients, is still acceptable, indicating that age >80 years should not be an exclusion criteria for EVAR. Even high-risk patients >80 years can be treated safely with a low perioperative mortality and comparable midterm outcome to younger high-risk patients.

To assess whether the preoperative level of deoxygenated hemoglobin (HHb) in the calf muscle during light-intensity exercise is useful for identifying patients at risk of developing deep vein thrombosis (DVT) after total knee or hip arthroplasty. ⋯ NIRS-derived RI >2.3 may be a promising parameter for identifying patients at risk of developing postoperative DVT despite pharmacologic DVT prophylaxis. A GV diameter of >0.25 cm also seems to contribute to the development of postoperative DVT. These results might be helpful to physicians for deciding which patients require more intensive thromboprophylaxis.

Multicenter Study
Thrombolysis for lower extremity bypass graft occlusion.
Thrombolysis is a common method in the treatment of lower extremity bypass graft occlusion. The purpose of this study was to investigate the results of thrombolytic therapy in the management of acute bypass graft occlusion and to identify risk factors for technical failure and amputation. ⋯ Our findings support the use of thrombolysis in the treatment of acute bypass graft occlusion in the lower limb given its acceptable short- and long-term amputation-free survival rates. Technical failure and higher age were factors associated with major amputation. Synthetic grafts appeared to have a somewhat increased likelihood of technically successful thrombolysis compared with vein grafts, but on the other hand, they exhibited an increased risk of amputation during follow-up.
