The right vertebral artery most commonly originates as the first branch of the right subclavian artery. Although anatomical variants of the aortic arch are commonly encountered on cross-sectional imaging, certain variants of the right vertebral artery are exceedingly rare. In this report, we present 3 cases of aberrant right vertebral artery arising as the last branch of the aortic arch, a very rare variant.

BACKGROUND: Validation of subclavian duplex ultrasound velocity criteria (SDUS VC) to grade the severity of subclavian artery stenosis has not been established or systematically studied. Currently, there is a paucity of published literature and lack of practitioner consensus for how subclavian duplex velocity findings should be interpreted in patients with subclavian artery stenosis. OBJECTIVE: The objective of the present study was to validate SDUS measurements using subclavian conventional or computed tomography angiogram (subclavian angiogram [SA])-derived measurements...

Takayasu arteritis manifests with arterial occlusions and aneurysms. Revascularization is sometimes challenging, especially when carotid arteries are affected. In this report, we present a carotid artery revascularization technique in a patient who was admitted with orthostatic and postprandial transient ischemic attacks, resulting in a diagnosis of bilaterally occluded subclavian and vertebral arteries, occluded left common carotid artery, and severely stenosed right common carotid artery. Clamping of the right carotid artery was a challenge; however, our technique provides a neurologically safe revascularization...

BACKGROUND: Optimising filter life and performance efficiency in continuous renal replacement therapy has been a focus of considerable recent research. Larger high quality studies have predominantly focussed on optimal anticoagulation however CRRT is complex and filter life is also affected by vascular access, circuit and management factors. We performed a systematic search of the literature to identify and quantify the effect of vascular access, circuit and patient factors that affect filter life and presented the results as a meta-analysis...

BACKGROUND: Active fixation leads have provided stable atrial and ventricular pacing; however, long-term follow-up data have not been satisfactory. The purpose of this study was to investigate the long-term reliability of active fixation leads and their electrical characteristic stability. METHODS: A total of 1196 pacing leads were implanted in 830 patients consecutively between 2002 and 2013. In this retrospective study, we were able to trace 1092 leads in 750 patients to investigate the prognosis of implanted leads...

BACKGROUND: Aortic arch disease is a challenging clinical problem, especially in high-risk patients, in whom open repair can have morbidity and mortality rates of 30% to 40% and 2% to 20%, respectively. Aortic arch chimney (AAC) stents used during thoracic endovascular aortic repair (TEVAR) are a less invasive treatment strategy than open repair, but the current literature is inconclusive about the role of this technology. The focus of this analysis is on our experience with TEVAR and AAC stents...

BACKGROUND: The best management strategy for the left subclavian artery (LSA) in pathologic processes of the aorta requiring zone 2 thoracic endovascular aortic repair (TEVAR) remains controversial. We compared LSA coverage with or without revascularization as well as the different means of LSA revascularization. METHODS: A retrospective chart review was conducted of patients with any aortic diseases who underwent zone 2 TEVAR deployment from 2007 to 2014. Primary end points included 30-day stroke and 30-day spinal cord injury (SCI)...

BACKGROUND: Symptomatic subclavian artery total occlusion is widely treated with an endovascular procedure, which often results in distal vertebral artery embolism. Therefore, protection devices are important. Setting up a filter or balloon device in the vertebral artery can protect against this distal embolism. However, the use of embolic protection devices is not easy and makes the procedure more complicated. Here we report a case of symptomatic subclavian artery total occlusion that was successfully treated with a balloon-guiding catheter and the pull-through technique...

Intravenous leiomyomatosis is a benign smooth muscle tumor that often occurs in the internal iliac vein and is closely associated with a fibroid. Intravenous leiomyomatosis usually starts in the veins of the uterus. It can grow within the veins and extend into the inferior vena cava and ultimately extend into the right-sided heart chambers and pulmonary arteries. Other sites are less common, and a venous primary site is very rare. We report a case of subclavian vein tumor that was diagnosed as an unusual leiomyoma in a 21-year-old nulliparous woman...

Though the variations of vertebral artery are clinically asymptomatic yet abnormalities are of diagnostic importance either prior to vascular surgery in the neck region or in patients of intravascular diseases such as arteriovenous malformations or cerebral aneurysms. Therefore, the aim of the study is to bring out 2 variations in the configuration of vertebral artery and their clinical implication. During dissection of thorax of 2 female cadavers, 2 different variants of configurations of left vertebral arteries were observed...

BACKGROUND: Prevalence of bicuspid aortic valve (BAV) and right aberrant subclavian artery (ASA) separately is relatively common in general population, and much higher in some disorders. Surprisingly, coexistence of both valve and vessel anomalies has only been reported in single cases. METHODS: From 2008 to 2016, in a single, high-volume tertiary cardiac center, patients who underwent chest computed tomography or magnetic resonance imaging for various reasons, were retrospectively screened for the presence of right ASA...

BACKGROUND: The temporal variation of the hemodynamic mechanical parameters during cardiac pulse wave is considered as an important atherogenic factor. Applying non-Newtonian blood molecular viscosity simulation is crucial for hemodynamic analysis. Understanding low density lipoprotein (LDL) distribution in relation to flow parameters will possibly spot the prone to atherosclerosis aorta regions. METHODS: The biomechanical parameters tested were averaged wall shear stress (AWSS), oscillatory shear index (OSI) and relative residence time (RRT) in relation to the LDL concentration...

BACKGROUND: The current indications of cardiac implantable electronic devices (CIEDs) have expanded to include young patients with serious cardiac risk factors, but CIED placement has the disadvantage of involving unsightly scarring and bulging of the chest wall. A collaborative team of cardiologists and plastic surgeons developed a technique for the subpectoral placement of CIEDs in young female patients via a transaxillary approach. METHODS: From July 2012 to December 2015, subpectoral CIED placement via an axillary incision was performed in 10 young female patients, with a mean age of 25...

Central venous catheter insertion and cancer represent some of the important predisposing factors for deep venous thrombosis (DVT). DVT usually develops in the lower extremities, and venous thrombosis of the upper extremities is uncommon. Early diagnosis and treatment of deep venous thrombosis are of importance, because it is a precursor of complications such as pulmonary embolism and postthrombotic syndrome. A 47-year-old woman visited our department with painful swelling on the left side of her neck. Initial examination revealed swelling of the region extending from the left neck to the shoulder without any redness of the overlying skin...

BACKGROUND: Endovascular therapy is well studied in atraumatic conditions; and there appears to be a growing interest in its application to traumatic injuries. The objective of this study is to compare open and endovascular techniques in the management of peripheral arterial trauma. METHODS: This is a retrospective review of patients admitted to a Level I Trauma Center sustaining injuries to the subclavian, axillary, superficial femoral, and popliteal arteries. Demographics, surgical interventions, complications, and clinical outcomes were evaluated in patients requiring open or endovascular repair between 2009 and 2015...

AIM OF THE STUDY: Coronary artery bypass graft surgery is the gold standard for the treatment of multivessel and left main coronary artery disease. However, there is considerable debate that whether left internal mammary artery (IMA) should be taken as pedicled or skeletonized. This study was conducted to assess the difference in blood flow after the application of topical vasodilator in skeletonized and pedicled IMA. MATERIALS AND METHODS: In this study, each patient underwent either skeletonized (n = 25) or pedicled IMA harvesting (n = 25)...

A 10-year-old dog weighing 3.4 kg presented with intermittent regurgitation. Esophagography revealed that the thoracic esophagus was compressed dorsally at the region of the fourth intercostal space and segmentally dilated from the second to third intercostal region. Three-dimensional computed tomographic (CT) angiography confirmed a suspected vascular ring anomaly and also revealed multiple other vascular anomalies. These included aberrant right subclavian artery, absence of bilateral external jugular veins, right-gastric caval shunt, and a completely duplicated caudal vena cava...
