A 77-year-old woman with arteriovenous shunt for hemodialysis in the left forearm suffered from subarachnoid hemorrhage due to the rupture of a saccular aneurysm located on the left lateral wall of vertebrobasilar junction. Her left subclavian artery was severely stenosed and subclavian steal phenomenon was demonstrated on the digital subtraction angiography. Embolization of the parent artery including the aneurysm using detachable coils resulted in the successful obliteration of the aneurysm through the revascularized left subclavian artery...

The phenomenon of coronary steal is well known in the setting of HLHS (Hypoplastic Left Heart Syndrome) early after the Classical Norwood Operation. We report a rare case of an infant with HLHS [Severe Aortic Stenosis (AS), Mitral Stenosis (MS) and small Left Ventricle (LV)], who developed aortic regurgitation and presumed coronary steal late after the Sano Modification of the Norwood Procedure. Coronary steal developed secondary to progressive aortic and mitral regurgitation and resulted in poor right ventricular function and severe tricuspid regurgitation...

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly which is one of leading causes of myocardial ischemia and infarction in children. If left untreated, it results in a 90% mortality rate in the first year of life. In patients who survive to the adulthood, the coronary steal phenomenon and retrograde left-sided coronary flow provide a substrate for chronic subendocardial ischemia, which may lead to left ventricular dysfunction, ischemic mitral regurgitation, malignant ventricular arrhythmias, and sudden cardiac death...

OBJECTIVES: Our goal was to report the selection schemes, technical variations and long-term outcome of extra-anatomical bypass to correct complex, recurrent aortic coarctation and hypoplastic aortic arch. METHODS: Between 1989 and 2012, 53 patients (mean age 13.2 ± 4.3, median 11.6, range 9-23 years) with complex aortic coarctation ( n  = 33; long-segment hypoplastic aortic arch in 15), recurrent coarctation ( n  = 20; anastomosic pseudoaneurysm in 10), underwent correction using extra-anatomical bypass, either with ( n  = 18: femoral bypass = 13, left heart bypass = 5) or without ( n  = 35) extracorporeal circulation via a left lateral thoracotomy ( n = 48) and combined median sternotomy and median laparotomy ( n  = 5)...

Large intercoronary communications in the absence of obstructive coronary artery disease constitute a very rare coronary artery anomaly in which there is a readily visible connection between the 2 coronary arteries with a unidirectional or bidirectional blood flow; consequently, this anomaly may be misinterpreted as a functioning collateral vessel, indicative of an unrecognized proximal coronary artery occlusion. In contrast to collateral vessels that are seen in the presence of critical coronary artery stenosis and total occlusions, these arterial communications are vessels that are single, extramural, straight, and large in diameter...

All biological processes are governed by principles of physics that dictate the pathophysiology and even the treatment of congenital heart diseases. In this review, basic concepts such as flow, pressure, resistance, and velocity are introduced, followed by more complex laws that describe the relationship between these variables and the disease processes. Finally, physical phenomena such as turbulence, steal and runoff phenomenon, and energy loss are discussed. By application of these principles, one can accurately quantify modifications undertaken to treat diseases, for example, the size of a patch that augments a vessel and the angle of an anastomosis to allow a certain flow...

BACKGROUND: The right-sided aortic arch (RAA) is a rare congenital defect of the aorta. The aim of the study was to assess the occurrence of RAA in diagnoses performed by the University Radiology Department and analyze the frequency of concomitant vascular abnormalities. METHODS: The database of the Radiology Department was retrospectively analyzed between January 2008 and May 2016 with the keyword "right aortic arch". Twenty patients with this diagnosis were identified from a total of 11,690 CT examinations of the chest area, 19,623 CT examinations of brain-supplying vessels, and 1863 MRI examinations of the heart and aortic arch or brain-supplying arteries...

The clinical benefits of using the left internal mammary artery (LIMA) to bypass the left anterior descending artery are well established making it the most frequently used conduit for coronary artery bypass surgery (CABG). Coronary subclavian steal syndrome (CSSS) occurs during left arm exertion when (1) the LIMA is used during bypass surgery and (2) there is a high grade (≥75%) left subclavian artery stenosis or occlusion proximal to the ostia of the LIMA resulting in "stealing" of the myocardial blood supply via retrograde flow up the LIMA graft to maintain left upper extremity perfusion...

Atherosclerosis affecting the carotid arteries accounts for up to 20% of ischemic strokes 1. The clinical effects of atherosclerotic occlusive disease vary according to multiple factors, one of which is collateral circulation. In response to a chronic decrease in cerebral perfusion from atherosclerotic occlusion, alternative flow pathways, or collaterals, develop in a variety of patterns. In the setting of carotid occlusion, flow from the Circle of Willis, if complete, often comprises the main cerebral collateral network...

Moyamoya disease is characterized by bilateral progressive terminal internal carotid arteries steno-occlusion. In this patient, the disease affected middle cerebral arteries and was disclosed after a left frontal cerebral infarction. Brain HMPAO perfusion scintigraphy with acetazolamide challenge, obtained before surgical treatment, demonstrates an extended bilateral frontal hypoperfusion with a vascular steal phenomenon. The same examination obtained after surgical treatment demonstrates a frank improvement in basal brain vascularization, with nearly complete correction of vascular steal phenomenon...

Coronary subclavian steal syndrome (CSSS) is a well-recognized phenomenon secondary to coronary artery bypass grafting and may cause myocardial ischemia. We report 2 cases of CSSS successfully treated with subclavian artery (SA) stenting. In both cases, an Optimo balloon guiding catheter was placed in the SA immediately proximal to the vertebral artery (VA) origin as a double protection system for the VA and left internal thoracic artery (LITA) graft. There were no periprocedural complications. Balloon protection for both the VA and LITA using a single balloon guiding catheter is a reasonable and safe technique for preventing distal embolisms...

Coronary-subclavian artery (SCA) steal syndrome is an uncommon phenomenon in which coronary flow is diverted into the SCA through the patent left internal mammary artery (LIMA) conduit due to critical subclavian stenosis. The prevalence of significant left SCA (LSCA) stenosis in patients, referred for coronary bypass surgery, has been reported to be 0.2 to 6.8%. Most patients usually present with angina pectoris, and secondary myocardial infarction is rarely reported. Herein, we present a case of coronary bypass graft in which a left anterior descending artery-LIMA graft was applied to supply the left arm due to complete LSCA occlusion...

Background The treatment of brain arteriovenous malformations (AVMs) has been studied extensively. With the use of the Spetzler-Martin (S-M) grading system, patients can be informed appropriately about their possible surgical risks. This does not hold true for their neuropsychological sequelae, which have not been studied widely. We evaluated the neuropsychological outcome of our patients treated for brain AVMs. Methods Of 113 patients treated for a brain AVM between 2001 and 2009, 66 patients were enrolled in the study...

Subclavian steal is a relatively common vascular phenomenon usually caused by atherosclerotic disease. While symptoms are rare, arm claudication of the ipsilateral limb is most common, with paroxysmal symptoms of vertebrobasilar insufficiency (often exercise induced) being relatively uncommon. Here we present a case of brachial artery embolism during mechanical thrombectomy for basilar artery thrombosis, secondary to subclavian steal phenomenon. This atypical and potentially irreversible complication should be considered in patients with acute ischemic stroke undergoing neurointerventional management when subclavian steal is discovered angiographically...

Kommerell's diverticulum (KD) is defined as a bulbous dilatation of the origin of an aberrant subclavian artery due to a remnant of the left fourth aortic arch. We report the case of an asymptomatic woman in whom progressive thrombosis of the KD extending to the prevertebral tract of an aberrant right subclavian artery was detected at multidetector computed tomography imaging for lung cancer staging performed before and after the beginning of chemotherapy. Reversed blood flow in the ipsilateral vertebral artery due to subclavian steal phenomenon was also observed by color Doppler ultrasound examination...

The subclavian-vertebral artery steal syndrome (SSS) is the hemodynamic phenomenon of blood flow reversal in the vertebral artery due to significant stenosis or occlusion of the proximal subclavian artery or the innominate artery. Occasionally, SSS is diagnosed in patients not harboring arterial stenosis. With the exception of arterial congenital malformations, the limited case reports of SSS with intact subclavian artery are attributed to dialysis arteriovenous fistulas (AVFs). Interestingly, these cases are more frequently symptomatic than those with the classical atherosclerotic SSS forms...

BACKGROUND: The omental flow-through flap (OFTF) is based on the use of an anatomic unit composed of the right gastro-omental artery (bypass) with its omental branch or branches supplying the greater omentum (flap). The greater omentum flap is known for its capacity of resistance to infection, for its use in the treatment of ischemic lesions and as a high-flow tissue. Several hypotheses regarding the hemodynamic behavior of a distal bypass with a flap were discussed in the literature...

Myocardial infarction in the absence of coronary artery disease is a rare finding. Mechanisms leading to infarction include paradoxical embolism, coronary dissection, coronary spasm, hypercoagulable states, vasculitis, or-in presence of a coronary fistula-a steal phenomenon. We report for the first time a case of a patient with an arteriovenous coronary fistula and no coronary artery disease, suffering from three incidents of myocardial infarction in three different coronary regions-of which only one was located in the area supplied by the coronary artery connected to the fistula...
