Randomized Controlled Trial Comparative Study
Less painful tumescent solution for patients undergoing endovenous laser ablation of the saphenous vein.
This study aims to investigate the efficacy of lidocaine, prilocaine, and bupivacaine used in tumescent solution during endovenous laser treatment (EVLT) on intraoperative and postoperative pain. ⋯ Tumescent anesthesia is the most critical component of EVLT to improve comfort by reducing the pain. Therefore, we conclude that bupivacaine is an optimal alternative to lidocaine and prilocaine in tumescent anesthesia and can be used safely.

Comparative Study
Does the technique of carotid endarterectomy determine postoperative hypertension?
Hypertension (HT) after carotid endarterectomy (CEA) is a risk factor for postoperative myocardial infarction, stroke, and neck hematoma. We compared the incidence of postoperative HT within the week after eversion CEA (e-CEA) and patch closure CEA (p-CEA). Postoperative HT was defined as a systolic blood pressure (sBP) ≥ 160 mm Hg and/or the need for postoperative vasodilatators. The aim of our study was to determine if the technique of CEA had an effect on postoperative HT. ⋯ The e-CEA technique is not a risk factor and does not have an effect on postoperative HT. The postoperative sBP was more stable in this group. Eversion carotid endarterectomy has been considered, in the literature, as a risk factor of postoperative hypertension. We conducted a large prospective and comparative study of the endarterectomy technique by eversion and with conventional patch closure. The primary end point was the blood pressure value and the administration of antihypertensive treatment. Our study shows that postoperative hypertension after carotid endarterectomy is not related to the surgical technique. Changes in blood pressure after carotid endarterectomy by eversion are lower than those observed after conventional endarterectomy with patch closure. This technique prevents the occurrence of possible hypotension occurrence, which can be the cause of perioperative complications.

The use of endovascular technology for mesenteric interventions has become an increasingly accepted treatment modality. We present an unusual case of celiac artery stent placement for coronary ischemia. ⋯ Use of arterial conduits for CABG have proven to be superior to vein. Long-term viability of the GEA as a conduit is dependent in part on the patency of mesenteric circulation. Our findings demonstrate a viable endovascular treatment option for angina pectoris secondary to mesenteric stenosis in this unique patient population.

Observational Study
Current factors of fragility and delirium in vascular surgery.
Vascular surgery patients are frequently deemed to be in a frail clinical condition and at risk for delirium. Therefore, we evaluated the incidence and independent perioperative risk factors for delirium. In addition, we describe factors on frailty in the various vascular disease groups in current practice. ⋯ Delirium is a frequent complication in vascular surgery clinical practice, especially in the elderly. Nurse visits at patients' homes and the Amphia Risk Score for delirium were independent risk factors for delirium in our study population. In this study, we identified patients with critical limb ischemia as the most frail and vulnerable.

Comparative Study
Racial disparities in outcomes of endovascular procedures for peripheral arterial disease: an evaluation of California hospitals, 2005-2009.
Racial/ethnic disparities in treatment outcomes of peripheral arterial disease (PAD) are well documented. Compared with non-Hispanic (NH) whites, blacks and Hispanics are more likely to undergo amputation and less likely to undergo bypass surgery for limb salvage. Endovascular procedures are being increasingly performed as first line of therapy for PAD. In this study, we examined the outcomes of endovascular PAD treatments based on race/ethnicity in a contemporary large population-based study. ⋯ In this contemporary large population-based study, we demonstrated that even among matched cohorts Hispanics and blacks have worse amputation-free survival than NH whites following endovascular therapy. Our study also found that Hispanics and blacks are more likely to undergo lower extremity arterial reinterventions than NH whites. Further research is crucial in understanding if higher reintervention rates in Hispanics and blacks are because of more severe disease and/or poor access to proper follow-up care and optimal medical management.
