Improved patency after axillofemoral bypass for aortoiliac occlusive disease.

Objective: Axillofemoral bypasses (AxFBs) have been used since 1962 to treat aortoiliac disease. In the past, reported patency rates (37%-76%) for these extra-anatomic grafts have been inferior to those for anatomic aortic grafting. Reported low survival rates after AxFB (40%-50%) have confirmed that these procedures have been used primarily in patients at high risk for complications from aortofemoral bypass.

Heparin-bonded expanded polytetrafluoroethylene femoropopliteal bypass grafts outperform expanded polytetrafluoroethylene grafts without heparin in a long-term comparison.

Objective: Expanded polytetrafluoroethylene (ePTFE) grafts have become an acceptable prosthetic alternative to autologous vein for infrainguinal arterial reconstructions. Recently, heparin bonding to the graft's luminal surface has been used as an adjunctive method of improving graft patency. We retrospectively evaluated a prospective experience with heparin-bonded ePTFE (HePTFE) vs the results of a prior experience with standard ePTFE (SePTFE) to compare patency rates in above-knee (AK) and below-knee (BK) femoropopliteal bypass through the 5-year follow-up.

Endovascular brachytherapy for renal artery in-stent restenosis.

Objective: Renal artery in-stent restenosis (RAISR) is not an infrequent occurrence and may be in part responsible for the failure of renal stents to improve clinical outcome. A variety of treatments have been used to restore patency, with mixed results. These include repeated percutaneous transluminal renal angioplasty (PTRA), repeated PTRA with bare-metal stents, and repeated PTRA with drug-eluting stents or covered stents.

Essentials of negotiating for employment in a changing environment.

Evolving changes in health care in the United States are causing new graduates and self-employed physicians to consider employment with large groups and health systems. Familiarity with the principles, proper conduct, and mechanics of negotiating an employment agreement will be important for vascular surgeons making such a decision. The various components of compensation packages and contract language need to be critically evaluated.

Contralateral carotid artery occlusion is not a contraindication to carotid endarterectomy even if shunts are not routinely used.

Objective: Although controversial, carotid artery stenting (CAS) has been proposed as being safer than carotid endarterectomy (CEA) for patients with a contralateral internal carotid occlusion (CCO). Arguably, with a CCO, CAS should be even safer than CEA if a shunt is not used. Accordingly, we reviewed our experience with 2183 CEAs performed routinely without a shunt to evaluate the risk of CEA performed in a subset of 147 patients with a CCO.

The role of completion imaging following carotid artery endarterectomy.

A variety of completion imaging methods can be used during carotid endarterectomy to recognize technical errors or intrinsic abnormalities such as mural thrombus or platelet aggregation, but none of these methods has achieved wide acceptance, and their ability to improve the outcome of the operation remains a matter of controversy. It is unclear if completion imaging is routinely necessary and which abnormalities require re-exploration. Proponents of routine completion imaging argue that identification of these abnormalities will allow their immediate correction and avoid a perioperative stroke.

Influence and critique of the JUPITER Trial (Statins v no statins for primary prevention of cardiovascular events in patients with normal lipids and elevated C-reactive protein).

Perhaps no recent trial in primary prevention of cardiovascular disease has resulted in more controversy than the JUPITER (Justification for the Use of Statins in Prevention: An Intervention Trial Evaluating Rosuvastatin) trial, which was first published in 2008. The study evaluated a patient cohort previously considered to be "healthy," ie, men 50 years of age or older and women 60 years of age or older, who did not have a history of cardiovascular disease and, at the initial screening visit, had a low-density lipoprotein cholesterol level of <130 mg/dL (3.4 mmol/L) and a high-sensitivity C-reactive protein level ≥2.

Private practice perspective on conflict of interest mandates.

This article assesses the current mandates on conflict of interest issues as they affect the practice of community-based vascular surgery and the pharmaceutical and medical technology industries and expresses the views of a private practice vascular surgeon. Scenarios where conflict of interest may occur are presented with assessments on how these scenarios will play out if such mandates are enforced.

Long-term safety of left renal vein division and ligation to expedite complex abdominal aortic surgery.

Background: Left renal vein division and ligation (LRVDAL) is performed to facilitate complex abdominal aortic surgery. Surgeons restore continuity of the vein due to concern that ligation could cause renal compromise or hematuria. However, we report the short and long-term safety of left renal vein division and ligation.

Setting up an imaging center, adding CT, MR, [corrected] and an angiography suite to vascular labs.

Computed tomographic angiography (CTA), magnetic resonance angiography (MRA), and diagnostic arteriography are all vascular diagnostic tools that may be included in modern vascular diagnostic laboratories. Before undertaking the establishment of such an all-purpose diagnostic, and possibly interventional, facility the vascular specialist or group needs to ensure safe patient care and the ability to provide these diagnostic tests and procedures without incurring a financial loss. This article will detail one method of setting up such a facility and suggest some other approaches.

Risk stratification in critical limb ischemia: derivation and validation of a model to predict amputation-free survival using multicenter surgical outcomes data.

Background: Patients with critical limb ischemia (CLI) are a heterogeneous population with respect to risk for mortality and limb loss, complicating clinical decision-making. Endovascular options, compared with bypass, offer a tradeoff between reduced procedural risk and inferior durability. Risk stratified data predictive of amputation-free survival (AFS) may improve clinical decision making and allow for better assessment of new technology in the CLI population.
