Ligation and division of the saphenofemoral junction (L/D SFJ) can protect against the danger of venous thromboembolism (VTE) associated with greater saphenous vein (GSV) radiofrequency ablation (RFA). Although this procedure is regarded as clean from an infection standpoint, surgical site infection (SSI) can offset its thromboembolic benefit. We questioned whether SSI associated with L/D SFJ could be minimized by a single preoperative dose of antibiotic. ⋯ L/D SFJ combined with RFA of the GSV, when treated as a clean procedure and not prophylaxed with antibiotic, carries a significant risk of SSI. While diabetes and high body mass index are patient-associated SSI risk factors, a single dose of preoperative antibiotic significantly reduces the rate of all infection, eliminates the danger of serious infection, and is associated with minimal VTE.

Case Reports
Combined emergency abdominal aortic aneurysm repair and valve replacement in a patient with severe aortic stenosis.
Simultaneous open surgery has been advocated in the elective management of abdominal aortic aneurysm patients with significant ischemic heart disease, as staged procedures risk worsening myocardial ischemia or aortic rupture, depending on which is the first intervention. The argument for combined aneurysm and valve repair is less established. ⋯ The patient was successfully managed with emergency combined open abdominal aortic aneurysm repair and open aortic valve replacement. We would advocate that such a strategy be considered as a salvage technique in similarly difficult management dilemmas.

Review Meta Analysis
Updated systematic review and meta-analysis of randomized clinical trials comparing carotid artery stenting and carotid endarterectomy in the treatment of carotid stenosis.
To compare carotid artery stenting (CAS) versus carotid endarterectomy (CEA) in the treatment of carotid stenosis, including two recently published, large, prospective, randomized trials of these therapies. ⋯ CAS is inferior to CEA with regard to the incidence of stroke or death for periprocedural outcomes, especially in symptomatic patients. However, CAS was associated with a lower incidence of myocardial infarction. These procedures may be considered complementary rather than competing modes of therapy, each of which can be optimized with careful patient selection.

Comparative Study
A positron emission tomography/computed tomography (PET/CT) evaluation of asymptomatic abdominal aortic aneurysms: another point of view.
To assess the prevalence of increased (18)F-fluorodeoxyglucose (FDG) uptake in aneurysmal walls, adopting a case-control approach in a population of asymptomatic patients with abdominal aortic aneurysm (AAA). ⋯ In conclusion, our results suggest that FDG hot spot, as well an increased diffuse uptake of FDG, in PET/CT studies is an extremely rare finding in patients with AAA of diameter close to surgical indications.

The patient, a 55-year-old female Jehovah's Witness who had suffered type B aortic dissection since the age of 53 years, presented with enlargement of the false lumen in the distal aortic arch and was subsequently admitted to our hospital. While hospitalized, her enlarged false lumen ruptured and she underwent replacement of the distal aortic arch and descending thoracic aorta without blood transfusion. Blood conservation strategies for this patient included the following: 1) meticulous hemostasis when incising muscle or soft tissue, 2) minimal use of gauze and discard suckers, 3) exclusive use of a cell salvage device "from skin to skin," 4) low-prime cardiopulmonary bypass, 5) minimal laboratory blood sampling, and 6) preoperative and postoperative erythropoietin treatment. ⋯ The patient had an uneventful postoperative course, except for prolonged rehabilitation. The postoperative lowest Hb value was 5.2 g/dL on postoperative day 5, and the Hb value at hospital discharge (postoperative day 55) was 11.0 g/dL. Our experience with blood conservation surgery on this Jehovah's Witness patient suggests that ruptured chronic type B aortic dissection can be safely repaired on bypass through a left thoracotomy with no blood transfusion if the preoperative Hb value is >10.0 g/dL.
