Coronary subclavian steal syndrome causing acute coronary syndrome: a case report.

Project description:BackgroundMyocardial infarction on non-occluded coronary artery represents a very specific subset of acute coronary syndrome (ACS). Coronary subclavian steal syndrome (CSSS) is defined by a left subclavian artery stenosis in case of (i) left internal mammary artery (LIMA) used to bypass left anterior descending artery (LAD) and (ii) >75% stenosis of the left subclavian artery prior to the origin of the LIMA to LAD graft. Here we report the case of a CSSS causing ACS.Case summaryA 71-year-old man with history of LIMA to LAD coronary artery bypass surgery was admitted to the nephrology intensive care unit for acute kidney injury requiring dialysis. Due to rapid deterioration, altered left ventricular ejection fraction and elevated c-troponin levels, an urgent coronary angiography was performed. It revealed a subtotal occlusion of the left subclavian artery prior to the origin of the LIMA to LAD graft. This was responsible for a severely altered coronary flow in the LIMA and LAD. Revascularization of the proximal left subclavian artery with a stent was performed, enabling instant recovery of distal coronary flows.DiscussionACS due to CSSS in this report highlights the complexity of the cardio-renal interaction. Patients with coronary artery bypass graft and chronic kidney disease commonly exhibit a higher risk for severe progression of atherosclerosis at multiple sites. CSSS treatments include secondary prevention measures and revascularization (if indicated) such as an endovascular approach.

Coronary subclavian steal syndrome-is there a need for routine assessment for subclavian artery stenosis following coronary bypass surgery?

Project description:Subclavian artery stenosis (SAS) resulting in coronary subclavian steal syndrome (CSSS) is a common but under recognized pathology following coronary artery bypass surgery (CABG). Patients with SAS may be asymptomatic due to the sub-clinical diversion of blood flow from the myocardium and retrograde blood flow during catheter angiography in the left internal mammary artery (LIMA) may be the first suggestion of CSSS. The management of SAS, causing CSSS, may rarely require acute assessment and intervention. However, full anatomical assessment of the stenosis morphology may be limited on fluoroscopy. Correction of SAS may be essential to achieve effective reperfusion therapy.

Coronary subclavian steal syndrome due to thrombosis of the left subclavian artery aneurysm: a case report.

Project description:BackgroundCoronary subclavian steal syndrome (CSSS) is an often easily overlooked cause of angina that may occur after a coronary artery bypass graft (CABG) procedure. The onset of CSSS several years after coronary revascularization has been described in case reports, and in the few retrospective reviews that compare the endovascular approach with surgical treatment. Subclavian stenosis can naturally coincide with coronary artery disease and may already be present during the initial CABG.Case summaryA 59-year-old male with a history of three-vessel disease who had a left internal mammary artery (LIMA) bypass graft, exhibited a gradual worsening of angina that coincided with numbness and impaired function of the left fingers, hand, and arm. Myocardial perfusion imaging showed reversible ischaemia, and coronary angiography suggested a thrombotic lesion proximal to the LIMA ostium. Calcified and partially thrombosed proximal left subclavian artery (LSA) aneurysm was visualized using computed tomography imaging, whereas Doppler ultrasound revealed a partially reversed vertebral flow. The lowest risk treatment was a bypass between the left common carotid artery and the LSA. The procedure was immediately successful, with cessation of symptoms and a favourable medium-term outcome.DiscussionAs no guidelines exist for such cases, the importance of multidisciplinary co-operation in diagnostics and devising a treatment plan is underlined. Moreover, screening for subclavian artery stenosis in CABG candidates should be warranted as part of the initial preoperative assessment.

Chronic vertebrobasilar insufficiency in subclavian steal syndrome.

Project description:Subclavian steal syndrome is a vascular disorder that consists of significant blood supply restriction with resultant insufficiency of the vertebrobasilar artery and the subclavian artery causing symptomatic insufficiency to the brain and upper extremity. It is important to recognize this condition in patients with subacute to chronic posterior circulation vascular insufficiency as early diagnosis and treatment can have good clinical outcomes (J Clin Neurosci. 2010;17:1339). CT angiogram of the head and neck should be considered in patients with chronic vertebrobasilar insufficiency to evaluate subclavian steal syndrome.

Coronary-subclavian steal syndrome: a case report of a rare entity that can become a deadly threat.

Project description:BackgroundIn patients who underwent coronary artery bypass graft (CABG), the coronary-subclavian steal syndrome (CSSS) is characterized by a subclavian artery stenosis proximal to the origin of the internal mammary artery resulting in functional graft failure.Case summaryA 62-year-old gentleman underwent CABG following a non-ST elevation myocardial infarction and an angiogram showing left main stem and three-vessel disease. Forty-eight hours later he developed cardiogenic shock that improved with inotropic support and intra-aortic balloon pump insertion. However, 7 days later, he deteriorated again and even though the myocardial injury markers and echocardiogram were normal, an angiography was performed showing significant CSSS. Due to the chronic nature of his subclavian stenosis and the severity of the cardiogenic shock, the heart team decided to treated his epicardial disease percutaneously and occlude the left internal mammary artery in its mid-segment with coils. The patient was discharged home 28 days after CABG and has remained since asymptomatic with improvement in his functional class.DiscussionCoronary-subclavian steal syndrome is a rare but fatal complication with increased morbidity and mortality due to reduced awareness amongst medical professionals. Subclavian artery stenosis stenting is the gold standard treatment; herein we present a new approach for complex and very sick patients in whom it is not possible to open the subclavian artery percutaneously. Increased awareness and prompt diagnosis of this pathology in CABG patients are essential for successful outcomes.

Endovascular treatment of coronary subclavian steal syndrome: a case series highlighting the diagnostic usefulness of a multimodality imaging approach.

Project description:BackgroundCoronary subclavian steal syndrome (CSSS) is an uncommon complication observed in patients after coronary artery bypass surgery with left internal mammary artery (LIMA) grafts. It is defined as coronary ischaemia due to reversal flow from the LIMA to the left subclavian artery (SA) when a proximal left SA stenosis is present. In practice, the entire clinical spectrum of ischaemic heart disease, ranging from asymptomatic patients to acute myocardial infarction, may be encountered.Case summaryThree cases of CSSS recently detected at our hospital are being described. Two patients presented with an acute coronary syndrome, so diagnosis was suspected based on coronary angiography findings, as retrograde blood flow from LIMA to the distal SA was present. Myocardial ischaemia was documented by myocardial perfusion scintigraphy in one case. The third patient was asymptomatic and CSSS was suspected during physical examination and confirmed by computed tomography (CT). Endovascular intervention with balloon-expandable stent implantation of the stenotic SA was performed by vascular surgeons in all patients. No periprocedural complications occurred, and complete resolution of symptoms was achieved.DiscussionIn CSSS, subclavian angiography is the standard diagnostic test. However, other diagnostic techniques may be valuable to better clarify this challenging diagnosis. In the herein small series, the usefulness of a multimodality imaging approach including Doppler ultrasound, myocardial perfusion scintigraphy, and CT is well demonstrated. Furthermore, this study endorses the safety and utility of endovascular treatment in different clinical scenarios, including asymptomatic patients.

Endovascular treatment of coronary subclavian steal syndrome complicated with STEMI and VF: A case report and review of the literature.

Project description:Key Clinical MessageEndovascular treatment of coronary subclavian steal syndrome is usually successful and safe. However, it might be lethally complicated, such as our case of STEMI and ventricular fibrillation during stent deployment. Early diagnosis of subclavian stenosis, intermittent dilations of balloons during stent deployment, and choosing the accurate stent size are suggested to avoid such complications.
