Feasibility of Lipid Screening During First Trimester of Pregnancy to Identify Women at Risk of Severe Dyslipidemia.

Background Dyslipidemia is an important risk factor for atherosclerotic cardiovascular disease, especially when disease presents at a young age. Despite national screening guidelines to perform a lipid profile test in children and young adults, many reproductive-age women have not undergone lipid screening. Our objective was to assess the feasibility of lipid screening during the first trimester of pregnancy as a strategy to increase lipid screening rates among women receiving prenatal care. Methods and Results A nonfasting lipid panel was incorporated into routine prenatal care among obstetricians at a single academic clinic. Educational materials and a clinical referral pathway were developed for patients with abnormal results. Over 6 months, 445 patients had a first prenatal care visit. Of the 358 patients who completed laboratory testing, 236 (66%) patients completed lipid testing. Overall, 59 (25%) patients had abnormal results. One patient with previously undiagnosed suspected familial hypercholesterolemia was identified. Barriers to ordering lipid tests included the burden of reviewing additional laboratory results and uncertainty about patient counseling. Conclusions Implementation of nonfasting lipid screening as part of routine prenatal care during the first trimester is feasible and may play a crucial role in timely diagnosis and management of lipid disorders in women of reproductive age. Future work should focus on optimizing health system workflow to minimize burden on clinical staff and facilitate follow-up with appropriate specialists.

Patient Preference for Transradial Access over Transfemoral Access for Cerebrovascular Procedures.

PURPOSE: Shared decision-making, when physicians and patients collaborate and agree on health care decisions, is a key tenant of patient-centered care. Choice of access site for neurovascular procedures is rarely a shared decision point between physicians and patients. We present our initial evaluation of patient preference for radial over femoral access for cerebrovascular procedures. MATERIALS AND METHODS: IRB approved single-center, prospective, and consecutive survey of all patients undergoing transradial access for cerebrovascular imaging and intervention. Primary inclusion criteria were patients who had previously undergone a transfemoral access procedure and chose to have their second procedure via a transradial approach. All patients underwent pre-procedural neurologic and extremity exams (including Barbeau tests for radial access suitability prior to radial access), post-procedural neurological evaluation and radial access assessment post-procedure, and complete neurological and radial access-site evaluation in the neurointerventional outpatient clinic 1-2 week post-procedure. RESULTS: Twenty five consecutive patients who underwent radial access cerebrovascular procedures after previous femoral access cerebrovascular procedures (16 diagnostic angiograms and 9 interventional procedures) were included. No major complications (including hematomas, infection, or delayed radial artery occlusion) were encountered during the immediate post-procedurral period or on outpatient follow-up (average 8 days). On immediate post-procedural examination, 16% had mild bruising and 24% had mild pain at the radial access site. Of the 25 patients included in this study, 24 strongly preferred radial access over femoral access and reported that, if they needed another procedure, they would prefer radial access. CONCLUSION: There was nearly unanimous patient preference for radial over femoral access for cerebrovascular procedures in this single-center prospective analysis. There were no major complications and no incidences of delayed radial occlusion. In the current age of value-based and patient-centered medicine, the radial approach should be considered for nearly all neurovascular procedures.

Subclavian steal: Endovascular treatment of total occlusions of the subclavian artery using a retrograde transradial subintimal approach.

INTRODUCTION: In symptomatic subclavian steal syndrome, endovascular treatment is the first line of therapy prior to extra-anatomic surgical bypass procedures. Subintimal recanalization has been well described in the literature for the coronary arteries, and more recently, in the lower extremities. By modifying this approach, we present a unique retrograde technique using a heavy tip microwire to perform controlled subintimal dissection. METHODS: We present two cases of symptomatic subclavian steal related to chronic total occlusion of the left subclavian artery and right innominate artery, respectively. Standard crossing techniques were unsuccessful. Commonly at this point, the procedures would be aborted and open surgical intervention would have to be pursued. In our cases, retrograde access was easily achieved via an ipsilateral retrograde radial artery, using controlled subintimal dissection and a heavy-tipped wire. RESULTS: We were able to easily achieve recanalization in both attempted cases of chronic total occlusion of the subclavian and innominate artery, using a retrograde radial subintimal approach. Subsequent stent-supported angioplasty resulted in complete revascularization. No major complications were encountered during the procedures; however, one patient did develop thromboembolic stroke secondary to platelet aggregation to the stent graft, 9 days post-procedure. CONCLUSIONS: Endovascular treatment is considered the first-line intervention in medically refractory patients with symptomatic subclavian steal syndrome. In the setting of chronic total occlusions, a retrograde radial subintimal approach using a heavy tip wire for controlled subintimal dissection is a novel technique that may be considered when standard approaches and wires have failed.
