Patients with abdominal aortic aneurysms (AAAs) of less than 5.5 cm have no significant differences in clinical outcomes after endovascular repair (EVAR) than those with larger AAAs according to data from a five-year prospective clinical trial setting. The researchers maintain their recommendation that small aneurysms should not be treated surgically. Details of this study were presented at the 64th Vascular Annual Meeting presented by the Society for Vascular Surgery.

Vascular surgery may be accompanied by cardiovascular complications, like ventricular tachyarrhythmia (VT). Though, these arrhythmias initially might be asymptomatic, they can lead to increased risk for late sudden cardiac death after surgery. Researchers from the Netherlands believe that cardiac high-risk patients with new-onset perioperative VT might benefit from preemptive cardioverter defibrillator (ICD) implantation in addition to optimal focused medical therapy.

Researchers have found that less bone loss is experienced in an oral implant when a two-stage approach to surgery is used. Simultaneously inserted implants, which require one operation to transplant bone tissue and to insert implants into the jawbone, have shown excellent results. However, when the implants were inserted in a second operation about six months after the bone tissue grafts, crestal bone loss was reduced.
