Neurofibromatosis type 1 (NF-1) is an autosomal dominant disease primarily characterized by cutaneous café au lait macules, benign neurofibromas, and iris hamartomas. A spectrum of vascular abnormalities is associated with NF-1. We present a case of a 49-year-old female with NF-1 and spontaneous rupture of the infrarenal aorta caused by invasion of a neurofibroma and treated with endovascular stent grafting.

Introduction: Ultrasound-guided thrombin injection (UGTI) is a well-established practice for the treatment of femoral artery pseudoaneurysm. This procedure is highly successful but dependent on appropriate pseudoaneurysm anatomy and adequate ultrasound visualization. Morbid obesity can present a significant technical challenge due to increased groin adiposity, resulting in poor visualization of critical structures needed to safely perform the procedure. We aim to evaluate the safety and efficacy of UGTI to treat femoral artery pseudoaneurysm in the morbidly obese. Methods: This is a retrospective cohort study in which all patients who underwent UGTI at The Ohio State University Ross Heart Hospital from 2009 to 2014 were analyzed for patient characteristics and stratified by body mass index (BMI). Patients with BMI ≥ 35 were considered morbidly obese and were compared to patients with a BMI < 35. Outcome was failed treatment resulting in residual pseudoaneurysm. Results: Our cohort consisted of 54 patients who underwent thrombin injection. There were 41 nonmorbidly obese and 13 morbidly obese patients. Mean age was 64.5 years. The cohort was 44.4% male. There were 6 failures, of which 1 underwent successful repeat injection and 5 underwent open surgical repair. There was no statistically significant difference in failure between nonmorbidly obese and morbidly obese patients (9.8% vs 15.4%, P = .45). There were no embolic/thrombotic complications. Conclusion: Ultrasoundguided thrombin injection is a safe and effective therapy in the morbidly obese for the treatment of femoral artery pseudoaneurysm. In the hands of experienced sonographers and surgeons with adequate visualization of the pseudoaneurysm sac, UGTI should remain a standard therapy in the morbidly obese. [ABSTRACT FROM AUTHOR]

Radiotracer imaging allows for noninvasive detection and quantification of abnormalities in angiosome foot perfusion in diabetic patients with critical limb ischemia and nonhealing wounds. A 60-year-old male presented with critical limb ischemia (CLI), which was associated with second toe gangrene of the left foot (Panel A-1), a left limb ankle-brachial index (ABI) of 0.65, and bilateral claudication.

Vascular anomalies are extremely rare in patients with von Recklinghausen disease. This report presents a case of an acute spontaneous subclavian artery rupture in a patient with von Recklinghausen disease. A 44-year-old woman with a history of neurofibromatosis type 1, multiple sclerosis, and aortic valve replacement experienced a ‘‘popping sensation’’ in her neck. An emergent angiogram via a right brachial artery approach revealed active extravasation of contrast from the proximal part of the right subclavian artery between the vertebral and axillary arteries. An 8 mm × 5 cm endoprosthesis stent graft was placed across the area of extravasation via the brachial sheath. Completion angiography revealed brisk flow through the stent graft with resolution of the area of extravasation and no residual stenosis. Arterial rupture, aneurysm formation, stenosis, and dissection can be fatal in patients with neurofibromatosis. Further research is needed to determine screening guidelines and management algorithms for this patient population. [ABSTRACT FROM PUBLISHER]

The article focuses on the treatment and management of atherosclerotic disease. Topics discussed include risk factors associated with the same; role of the clinical pharmacist in an integrated heart and vascular clinic for the management of the same; and a table depicting type of intervention performed by the clinical pharmacist and acceptance rates such as aspirin, deletion of therapy and patient education.
