Perioperative outcomes after endovascular repair (EVAR) of abdominal aortic aneurysms (AAA) have been rigorously studied; however, inpatient and postdischarge outcomes have not been separately analyzed. The objective of this study was to examine postdischarge 30-day outcomes after elective EVAR. ⋯ Patient characteristics associated with a higher risk for postdischarge adverse events after EVAR were identified. Whether improved predischarge surveillance and close postdischarge follow-up of identified high-risk patients will further improve 30-day outcomes after EVAR needs to be prospectively studied.

Multicenter Study Comparative Study
Failure to rescue and mortality following repair of abdominal aortic aneurysm.
Recently, failure to rescue (FTR; death following major complication) has been shown to be a primary driver of mortality in highly morbid operations. Establishing this relationship for open and endovascular repair of abdominal aortic aneurysms may be a critical first step in improving mortality following these procedures. We sought to examine the relative contribution of severe complications and FTR to variations in mortality rate. ⋯ FTR appears to drive a large proportion of the variation in mortality associated with abdominal aortic aneurysm repair. The exact mechanisms underlying this variation remain unknown. Nonetheless, FTR is influenced by the structural characteristics and safety culture related to the timely recognition and management of severe complications. Hospitals that are unable to effectively handle severe complications following EVAR or OAR require close scrutiny.

Blunt injury of the abdominal aorta is highly fatal. We present an unusual case of an osteophyte impaling the abdominal aorta treated by endovascular repair. A 77-year-old man sustained a thoracolumbar fracture-dislocation with posterior aortic rupture between his celiac and superior mesenteric artery origins. ⋯ He was dismissed on postoperative day 6. At 6 months, he had returned to most preinjury activities, and at 2-year follow-up, he continues to have good functional outcome. Endovascular repair may be successfully employed in select aortic injuries in hemodynamically stable patients.

Review Meta Analysis
Bayesian network meta-analysis of nitinol stents, covered stents, drug-eluting stents, and drug-coated balloons in the femoropopliteal artery.
Several randomized controlled trials (RCTs) have shown the superiority of some of these technologies over balloon angioplasty, but direct comparisons between these treatment options are lacking. The authors conducted a network meta-analysis of RCTs comparing bare nitinol stents, covered nitinol stents, paclitaxel- or sirolimus-eluting stents (PES or SES), and paclitaxel-coated balloons (PCB) with plain balloon angioplasty or with each other in the femoropopliteal artery (PROSPERO registry: CRD42013004845). ⋯ Immediate technical success is better with the use of covered stents, whereas paclitaxel-eluting stents and paclitaxel-coated balloons offer the best long-term results in the femoropopliteal artery.

Thrombolysis as a treatment for acute limb ischemia (ALI) has become a first-line therapy based on studies published over 2 decades ago. The purpose of this study was to assess outcomes of patients treated for ALI using contemporary thrombolytic agents and endovascular techniques. ⋯ Endovascular therapy with thrombolysis using tissue plasminogen activator remains an effective treatment option for patients presenting with mild or moderate lower extremity ALI, with equal benefit derived with CDT or PMT. Patients with end-stage renal disease or poor pedal outflow have an increased risk of limb loss and may benefit from alternative revascularization strategies.
