Review Case Reports
Recurrent upper extremity embolism due to a crutch-induced arterial injury: a different cause of upper extremity embolism.
Acute embolism of the upper extremity is a relatively infrequent event compared to the lower extremity, but it will affect the function of the limb involved and may occasionally lead to amputation. Most upper extremity emboli are of cardiac origin, with the remainder arising from subclavian aneurysm, occlusive disease, or iatrogenic causes. ⋯ Frequently, this process is initially diagnosed and treated as a brachial artery embolism; such a misdiagnosis is associated with recurrent embolism. We report herein two uncommon cases of axillobrachial arterial injuries secondary to crutch trauma as a source of recurrent emboli to an upper extremity.

The prevalence of occlusive peripheral vascular disease in the superficial femoral artery approaches 20% in patients over the age of 60. Symptomatic peripheral arterial disease (intermittent claudication) is present in 3% to 7% of patients over the age of 60. The attraction of minimally invasive, percutaneous endovascular angioplasty (PTA) for this large number of patients has resulted in multiple trials of new PTA +/- stenting devices. The purpose of this report is to determine whether trials should include controlled patients who have optimal medical management including supervised exercise. ⋯ Endovascular treatment was superior to medical treatment in functional outcome at 1 year in only one of the five randomized trials for claudication. In the other four trials, medical treatment produced a greater maximum walking distance at 1 to 2 years. Current trials lack optimal medical controls. New trials of PTA + stent should include a medically managed group of patients in a supervised exercise program as the comparator arm. The outcome measure should be maximum walking distance to demonstrate added functional benefit of the new device.

Review Case Reports
Management of median arcuate ligament syndrome: a new paradigm.
Median arcuate ligament (MAL) syndrome is an anatomic and clinical entity characterized by extrinsic compression on the celiac axis, which leads to postprandial epigastric pain, vomiting, and weight loss. Although characterized a few decades ago, the existence of this syndrome is still challenged by several authors. We reviewed the management of MAL syndrome, with special emphasis on the minimally invasive approaches. ⋯ Laparoscopic release of arcuate ligament syndrome with intraoperative duplex ultrasound may be used in patients with symptoms suggestive of the diagnosis. In patients with persistent celiac flow abnormalities noted on duplex ultrasound or postoperative imaging, celiac angioplasty and stenting are advocated. If this option is not available or does not relieve symptoms, vascular reconstruction should be employed.

Review Case Reports
Gluteal compartment syndrome following abdominal aortic aneurysm repair: a case report.
Compartment syndromes occur when the elevated tissue pressure within a confined limb's myofascial compartment exceeds capillary pressure, with subsequent neurovascular compromise. In order to reduce disability and the consequences of ensuring ischemia, it is essential for early recognition and intervention. This is more commonly recognized in the calf. We report an unusual case of gluteal compartment syndrome after abdominal aortic aneurysm (AAA) repair.

Review Meta Analysis
What is the evidence on efficacy of spinal cord stimulation in (subgroups of) patients with critical limb ischemia?
The use of spinal cord stimulation (SCS) has been advocated for the management of ischemic pain and the prevention of amputations in patients with inoperable critical limb ischemia (CLI), although data on benefit are conflicting. Several reports described apparently differential treatment effects in subgroups. The purpose of this study was to analyze the data on the efficacy of SCS and to clarify preselection issues. ⋯ The analysis did not indicate a subgroup of patients who might specifically be helped by SCS. Meta-analysis including all randomized data shows insufficient evidence for higher efficacy of SCS treatment compared with best medical treatment alone. Although some factors provide prognostic information as to the risk of amputation in patients with CLI, there are no data supporting a more favorable treatment effect in any group.
