Objectives: Open lower extremity revascularization is controversial among octogenarians; however, the indications for surgical bypass are higher in the elderly population. The aim of the study was to compare postoperative outcomes between octogenarians and non-octogenarians following femoropopliteal bypass surgery.
Methods: Our regional, multi-institutional database was queried for femoropopliteal bypass procedures performed between 1995 and 2020. Electronic medical records were individually reviewed for operative and postoperative data. Univariable and multivariable logistic regression were utilized to determine predictors of postoperative outcomes.
Results: Among 1315 patients who underwent femoropopliteal bypass, 234 (17.8%) were octogenarians. Octogenarians more frequently underwent bypass for lower extremity tissue loss (48.7% vs 30.2%), whereas claudication was more common among non-octogenarians (24.0% vs 9.8%) ( < .001). Below-knee bypass target (72.2% vs 59.3%) and prosthetic conduit utilization (58.5% vs 43.7%) were more frequent in octogenarians ( < .001 each). Overall hospital length of stay was longer among patients > 80 years (median 6 days [interquartile range [IQR] 4-9] vs 5 days [IQR 4-8], = .017). The overall 30-day (5.6% vs 1.5%) and one-year mortality rates (25.6% vs 7.9%) were higher among octogenarians ( < .001 each). On multivariable analysis, age greater than 80 years was found to be an independent risk factor for postoperative mortality (OR 3.79 [1.75-8.20], = .0007).
Conclusions: Octogenarians undergoing bypass femoropopliteal bypass surgery have considerably worse postoperative outcomes, compared with non-octogenarians. These data may help inform elderly patients prior to undergoing open lower extremity revascularization.

Introduction: Initial surgical revascularization has a recognized primary role in patients with critical limb-threatening ischemia with a high-quality great saphenous vein for conduit. However, approximately one-third of lower extremity vein grafts develop lesions threatening graft patency. Traditional treatments have limitations, highlighting the need for innovative solutions.

Article Synopsis
- - The study investigates how collateral vessels, which develop from arterioles due to arterial issues, may provide a natural bypass to improve walking performance in patients with peripheral arterial disease after treatments like balloon angioplasty.
- - It analyzed medical data from 824 patients undergoing endovascular treatments for femoropopliteal chronic total occlusion, ultimately focusing on 410 limbs and looking at the relationship between collateral vessels and vessel dissection severity.
- - Results indicate that severe dissections were more common with specific lesion types, longer occlusions, and certain characteristics of collateral vessels, suggesting that these factors could help predict complications following treatment.

In patients with a femoropopliteal chronic total occlusion (CTO) after femoro-femoral (FF) bypass surgery, it is often difficult to perform endovascular therapy because of access site problems. We have treated two patients with CTO of the superficial femoral artery (SFA) using an FF crossover bypass graft. The two cases were a man with intermittent claudication and acute limb ischemia, respectively.

Article Synopsis
- * The study found that patients without healing had significantly higher rates of amputation and noncompliance compared to those whose ulcers healed, highlighting the importance of TCC adherence in treatment success.
- * Subgroup analysis revealed that patients undergoing revascularization interventions had better healing outcomes (66.7% healed) and noted lower ABI scores, indicating more severe vascular issues, compared to those who did not require additional procedures. *

Intravascular stent infections are often associated with high risks of morbidity and mortality. We report here a case of a patient with an arterial stent and recurrent septicaemias successfully treated with phage-meropenem combination therapy. A 75-year-old female with arteriosclerosis and comorbidities went through a femoropopliteal bypass with prosthesis in the right inguinal area.
