Carotid angioplasty and stent-induced bradycardia and hypotension: Impact of prophylactic atropine administration and prior carotid endarterectomy The administration of prophylactic atropine before balloon inflation during CAS decreases the incidence of intraoperative bradycardia and cardiac morbidity in primary CAS patients Hemodynamic instability due to hypotension and bradycardia in response to carotid artery stenting occurs in a relatively low proportion of patients. Elderly patients and those with coronary artery disease are at highest risk Carotid artery stenting (CAS) is the treatment of choice in high-risk patients with extracranial carotid occlusive disease. 1 Bradycardia and hypotension are well-recognized complications of this procedure and are often transient and self-limiting Carotid stent: Bradycardia cause During carotid angioplasty and stenting, a tiny balloon is inserted to widen the lumen of a stenotic carotid artery, and small metal stent is placed to prop it open and decrease the chance of restenosis
Diehm et al. conducted a study on the influence of stent type on hemodynamic depression after CAS and drew the conclusion that nitinol stents were associated with a higher risk of hypotension compared with braided Elgiloy stents during the procedure. However, procedural hypotension and bradycardia were not related to the incidence of major. Transient sinus bradycardia or asystole are relatively common physiological responses to balloon dilatation of carotid bifurcation lesions, particularly during post-dilatation stenting (5)
Bradycardia and hypotension have been observed after CAS with a reported incidence of 7% to 76%. 2, 3, 4, 5, 6, 7, 8 The causative factor is believed to be stimulation of the carotid sinus baroreceptors by the angioplasty balloon and intravascular stent Hypotension and bradycardia can occur during or after carotid artery stent placement (CAS) due to the stretching of the carotid sinus baroreceptors by the balloon and the stent
Among patients with hemodynamic instability or depression, which consists of hypertension, hypotension, or bradycardia after CEA or carotid stent placement, acute hypertension is attributed to the transient dysfunction of adventitial baroreceptors in patients who underwent endarterectomy, though metabolic factors such as renin and vasopressin have also been implicated. 8, 13, 14, 28 ⇓⇓⇓- 32 Our study revealed an increase in the tendency to present with AEs and hyperperfusion in apical lesions Carotid artery stenosis is responsible for approximately 20% of strokes annually. Carotid revascularization, in appropriately selected patients, reduces this risk. 1 Two different approaches for carotid revascularization exist, carotid endarterectomy (CEA) and carotid artery stenting (CAS). Each of these revascularization modalities has relative risks and benefits
No permanent neurological or cardiac sequelae were observed. CONCLUSION: Sustained hypotension with or without bradycardia may develop after carotid angioplasty and stent placement, presumably as a result of carotid sinus dysfunction Manipulation of carotid sinus during carotid surgery activates the carotid sinus reflex by stimulating the carotid sinus baroreceptors, which give rise to impulse carried via glossopharyngeal nerve to the medulla oblongata. These afferent impulses lead to the activation the cardiac vagal efferent nerve fibers, leading to cardiac bradycardia, AV. 11th Annual Cerebrovascular Symposium May 11-12. 2016 3 Post-op Carotid Management Objectives •Review the potential complications of carotid surgery •Cranial nerve palsies •Hemodynamic instability •Hyperperfusion syndrome •Stroke, MI •Post op neck hematoma •Discuss the clinical management of these complications when applicabl Factors associated with hypotension and bradycardia after carotid angioplasty and stenting Journal of Vascular Surgery, Vol. 46, No. 5 Electrophysiology and neuronal integrity following systemic arterial hypotension in a rat model of unilateral carotid artery occlusio Incidence of hemodynamic depression after carotid artery stenting using different self-expandable stent types.

Because the carotid endarterectomy literature has demonstrated poor outcomes after episodes of hypotension and bradycardia, this procedure has the potential to improve the safety of carotid angioplasty and stent placement (28, 33). The use of pacemakers reduced the incidence of bradycardia and hypotension to only 9%, as compared with the rate. Cayne N. , Faries P. , Trocciola S. , et al. Carotid angioplasty and stent-induced bradycardia and hypotension: impact of prophylactic atropine administration and prior carotid endarterectomy. J Vasc Surg. 2005 ;41: 956 - 961 The risk of bradycardia and hypotension after carotid stenting is directly related to the degree of dilation performed and may be observed up to twelve hours postoperatively. Postoperative hypotension correlates with increased in-hospital complications and long-term risk of death The bradycardia persisted for a few minutes after balloon deflation. One patient required permanent pacemaker placement 3 days after carotid stenting. Waigand et al 19 reported the development of a sinoatrial block in 40 of 50 patients with severe coronary artery disease during high-pressure inflation for carotid angioplasty followed by stenting
Bradycardia and hypotension have been observed after carotid artery stenting (CAS) with a reported incidence of 7% to 76% [1-7].The causative factor is believed to be the stimulation of the carotid sinus baroreceptors by balloon dilatation Intraprocedural bradycardia (heart rate < 60 bpm) developed in 29 patients (38%) and hypotension (systolic blood pressure < 90 mm Hg) occurred in 1 patient (1%) treated with stenting alone. Fourteen patients (70%) who underwent angioplasty and stenting had bradycardia, and hypotension developed in 4 (20%)

Factors associated with hypotension and bradycardia after carotid angioplasty and stenting Peter H. Lin, Wei Zhou, Panagiotis Kougias, Hosam F. El Sayed, Neal R. Barshes, Tam T. Huynh Thoracic & Cardiovascular Surger Hypotension and bradycardia have been described quite well after carotid procedures (both carotid endarterectomy and carotid stenting). Bradycardia and hypotension after these procedures is probably due to stimulation of the carotid body and a centrally mediated reflex (see relevant post).. However, hypertension has also been described after carotid procedures area.9 Additionally, carotid baroreceptor stimulation during CAS via a balloon or a carotid stent induces transient, some-times prolonged bradycardia and hypotension that can result in more intense cerebral ischemia than during clamping of the ICA in CEA. Furthermore, subsequent rebound arterial hyper Carotid endarterectomy (CEA) is the standard long-standing surgical procedure and was proved to be effective in preventing ischemic stroke in patients with moderate to severe carotid stenosis as long as three decades ago.[7,9] Because of recent advances in neuroendovascular surgery, carotid artery stenting (CAS) has become an alternative.
After the stent is placed successfully, flow reversal is turned off and blood flow resumes in its normal direction. TCAR not only obviates the need to navigate catheters through the aortic arch (a step linked to stroke during carotid stenting through the groin), but also prevents fragments of plaque released during stenting from travelling with. Europe PMC is an archive of life sciences journal literature Carotid artery stenting after the necessary preventive measures was successful. The article also considers possible risk factors of significant perioperative bradycardia during carotid angioplasty with stenting and measures preventing cardiac conduction perioperative worsening
We report a case of a 72-year-old man who had undergone elective stenting of an asymptomatic high grade stenosis of the proximal left internal carotid artery. The indication was progression of the stenosis over a 3 year period despite receiving maximal medical therapy, and patient preference for stenting over endarterectomy. He became profoundly hypotensive in the immediate post-stent period. Hemodynamic instability was defined as: 1) any episode of hypotension (that is, systolic BP lower than 90 mm Hg or a decrease of 50 mm Hg or more from the baseline BP) after stent deployment or balloon inflation; or 2) any episode of bradycardia after stent deployment or balloon inflation described by a heart rate lower than 60 bpm, an R-R.
Carotid artery stenting (CAS) leads to a greater decrease in blood pressure (BP) compared with carotid endarterectomy (CEA), although the effect is short-lived. What persists, though, according to results published online October 13, 2011, ahead of print in Stroke, is a decrease in antihypertensive medication use in CAS patients Mendelsohn FO, Weissman NJ, et al (2003) Hypotension and brady- et al (2000) Postprocedural hypotension Lederman RJ et al (1998) Acute cardia after elective carotid stenting: after carotid artery stent placement: hemodynamic changes during carotid frequency and risk factors. predictors and short- and long-term artery stenting
It is well recognized that hemodynamic instability consisting of hypertension, hypotension, or bradycardia often occurs after carotid endarterectomy (CEA) (4, 9, 16, 18, 19, 20, 26) and has been linked to surgical morbidity and mortality, especially to stroke and cardiac complications (1, 7, 9, 10, 12, 22).In particular, bradycardia and hypotension after CEA presumably result in increased.

The risk of stroke after carotid sinus massage is greater if there is preexisting carotid stenosis or carotid plaques. We present the case of a patient with underlying 40% carotid stenosis, who developed a watershed stroke after a self-neck massage in our stroke unit. We show a well-documented case with magnetic resonance images before and after the neck massage . Patients and Methods: This observational prospective (pilot) study included 20 patients—who underwent CAS. The study was carried out in Ain shams university hospitals—Railway hospital (ERMED) and Suez insurance hospital from December 2018 to February 2020 Bradycardia is seen consistently during predilation, stent deployment, and postdilation; there is, however, a trend toward greater hypotension during the stent delivery and postdilation. 18 Bradycardia (heart rate <60 beats per minute) occurs in 13% to 38% of patients and hypotension (systolic pressure <90 mm Hg) occurs in 5% to 26% of patients.

The long term performance (> 3 years) of carotid stents has not yet been established. As with any type of vascular implant, infection secondary to contamination of the stent may lead to thrombosis, pseudoaneurysm or rupture. The stent may cause a thrombus, distal embolization or may migrate from the site of implant through the arterial lumen The patient also suffered from hypotension and bradycardia, which was treated with neo-synephrine and atropine. The patient fully recovered with no deficits in less than 15 minutes. The patient underwent a cabg surgery 8 days later and was in recovery. The patient was discharged 21 days after the carotid stenting procedure In 46 consecutive patients with carotid artery stenosis, rSO2 was continuously recorded during and after CAS. In addition, the patients underwent SPECT to evaluate a change in CBF on the next day after CAS. Introprocedural bradycardia (heart rate <50 bpm) occurred in 21 patients (46%) including one transient cardiac arrest Objectives To assess the incidence and timing of hypotension after carotid artery stenting (CAS) and its correlation with postoperative complications. Background CAS‐associated postoperative hypotension has been linked to surgical morbidity and mortality, especially to stroke and cardiac complications.
