In patients receiving a first time permanent access, we found that the majority were AVF and they resulted in low primary patency rates at 1 year and long maturation times. KDOQI encourages AVF creation in order to increase AVF use for dialysis, but the strategy of simply increasing the number being created may not lead to the desired result and potentially lead to an increase in catheter dependence.

SIA for the treatment of lower extremity chronic arterial occlusions is technically feasible, results in minimal morbidity, and provides satisfactory revascularization without surgical bypass. Secondary patency is comparable to that of autologous vein bypass and is achieved with a low rate of reintervention. When used as first-line therapy, SIA provides most patients with limb salvage and freedom from surgical bypass at 3 years.

Selective stents placed for suboptimal results after subintimal angioplasty produce similar patency rates to primary SIA without stents. Patients receiving stents with prior lower extremity bypass surgery will have worse outcomes than those without. Use of a stent diameter < or =6 mm and indication of critical limb ischemia will likely produce worse results. It appears that other stent variables (location, number, length, and overlap) do not alter patency. Finally, selective stent use after SIA provides excellent limb salvage.

SIA is an effective percutaneous technique for the revascularization of patients with lower extremity chronic arterial occlusions involving the superficial femoral artery. The procedure is successfully performed in all segments of the lower extremity with minimal morbidity or mortality. Rates of limb salvage and improvement in claudication are similar to those achieved by open surgical bypass, while modest reductions in limb salvage and primary patency are experienced in limbs with femorotibial occlusions.

Background: Drug coated balloon (DCB) angioplasty significantly reduces reintervention rates in patients with symptomatic femoropopliteal peripheral artery disease (PAD). However, stand-alone DCB use in long, severely calcified lesions is frequently associated with vessel recoil and/or high-grade dissections necessitating provisional stent implantation.Objectives: Assess the safety and effectiveness of a vessel preparation strategy with directional atherectomy (DA) prior to DCB angioplasty in patients with symptomatic severely calcified femoropopliteal PAD.Methods: REALITY (NCT02850107) prospectively enrolled subjects at 13 multinational centers with 8-36 cm femoropopliteal stenoses or occlusions with bilateral vessel wall calcification treated with DA prior to DCB angioplasty. The primary effectiveness endpoint was 12-month primary patency, and the primary safety endpoint

We present our experience with an acute Stanford type B aortic dissection in a 25-year-old, 26-week gravid patient without a known connective tissue disorder and discuss a literature-based treatment strategy. After failed conservative treatment manifest by aneurysm rupture, emergency cesarean section delivery and immediate repair of her thoracic aorta was performed. Seven months later, she is fully caring for her healthy baby. During pregnancy, thoracic aortic dissection occurs from physiologic and hemodynamic changes. Emergency cesarean delivery, followed by immediate aortic repair, is the treatment choice if malperfusion syndrome, rupture, uncontrolled hypertension, or unremitting pain occurs.

Endovascular reintervention after SIA is a safe and technically feasible procedure for recurrences and offers good limb salvage rate. Early reinterventions performed within 3 months of the original SIA portend a worse outcome. In addition, reinterventions are less durable in patients with CLI compared with claudication. Finally, by identifying a recurrent stenosis instead of an occlusion, close surveillance may contribute to improved overall outcome.
