“…It is more commonly seen on the left side and is believed to be a result of the acute angle of origin of the left subclavian artery, which may result in local turbulence of blood flow and subsequent atherogenesis [ 3 – 6 ]. Other rare causes include large-vessel vasculitis (e.g., Takayasu or giant cell arteritis), extrinsic compression (costoclavicular syndrome), iatrogenic stenosis (e.g., radiation-induced), and congenital vascular anomalies [ 7 ].…”

We present a rare cause of subclavian steal syndrome secondary to a dialysis arteriovenous fistula (AVF). A 69-year-old female with end-stage renal disease presented with ataxia and recurrent fainting spells. Angiography revealed normal subclavian arteries bilaterally, a right VA origin occlusion, and an apparent left VA origin occlusion. However, carotid artery angiography demonstrated flow through the posterior communicating artery with retrograde filling of the basilar artery and left VA to its subclavian origin. Repeat left subclavian arteriography during external compression of the AVF demonstrated normal antegrade left VA flow. The AVF was subsequently ligated resulting in complete symptom resolution.

“…Physical examination findings suggestive of subclavian stenosis include a discrepancy of >15 mm Hg in blood pressure readings taken in both upper extremities, delayed or decreased amplitude pulses in the affected side, and a bruit in the supraclavicular fossa. 2,[8][9][10] A bruit in the suboccipital area may also be heard. The skin and nails of the affected side should be examined to rule out atrophic changes attributable to arterial insufficiency.…”

“…BP must be measured from the two arms at the first visit. If there is>10 mmHg difference between the two arms' records, causes such as peripheral vascular disease should be excluded first [11]. In the case of an unrecognized cause of the BP discrepancy between the two arms, the higher side record is usually taken as a real BP measurement because even one side's high records are associated with an increased rate of CVS events and death [12].…”

Increased blood pressure (BP) damages multiple organs. Diagnosis, treatment, and prevention of end-organ require regular, accurate BP measurement. BP was predominantly recorded using the mercury-based-sphygmomanometer. Recently, oscillometric-based devices have been invented and are commonly used worldwide. BP measurement methods are broadly divided into Office-based and out-of-clinic (home). The patient at home or workplace conducts home BP measurement, either intermittently (Non-ambulatory BP monitoring [NABPM]) or continuously (Ambulatory BP Monitoring [ABPM]). Despite the variety of BP measurement methods, the ABPM method is the best method of BP recording, especially in unstable (liable) BP readings. NABPM is conducted less frequently in the nighttime, whereas ABPM is conducted day and night and gives more frequent stable BP records. In ABPM, the mean of the measurements is automatically calculated and stored for later use or sent directly to the physician. Furthermore, some people may have an increase in BP at nighttime or loss of the dipping BP character, which increases the risks of high BP complications. Hence, in this comprehensive review, we will discuss the different methods of BP recording, their advantages and disadvantage, and their differences. Scopus, EMBASE, PubMed, Google, and Google Scholar were searched for the related reviews and original articles cited for BP measurement methods and techniques.
