Practical guide of vascular ultrasound in arteriovenous fistulae.

The use of vascular ultrasound, especially with the increasing prevalence of percutaneous arteriovenous fistulas, has taken a central role as a diagnostic and therapeutic imaging procedure in vascular access creation. The current review article stresses the importance of vascular ultrasound in arteriovenous fistula, from planning to creation to maintenance. It summarises and gives practical guidance regarding sonographic criteria for vascular access procedure planning, the application of vascular ultrasound intraoperatively and during follow-up.

Anomaly of Haughton type D left cervical aortic arch in combination with type B dissection: case report and literature review.

Background: The anomaly of cervical aortic arch is a rare phenomenon first described by Reid in 1914 and categorized by Haughton in 1975.

The role of atropine in carotid stenting of recurrent stenosis after eversion endarterectomy.

Objective: The value of prophylactic atropine use during carotid artery stenting (CAS) in primary carotid stenosis to prevent procedural hemodynamic depression is well accepted. However, its impact in case of recurrent stenosis after eversion carotid endarterectomy (E-CEA), which is known to be associated with decreased baroreflex function due to discontinuation of the carotid sinus nerve, has not been investigated so far.

Methods: The influence of angioplasty in the carotid bulb on intraprocedural and periprocedural hemodynamic changes (heart rate [HR], systolic blood pressure [SP], and diastolic blood pressure [DP]) of 38 CAS procedures (primary stenosis group, n = 16; post-E-CEA recurrent stenosis group, n = 22) was analyzed retrospectively.
