“…[15][16][17][18] A relevant naturally occurring and exceedingly rare phenomenon is the congenital absence or hypoplasia of one of the carotid arteries identified in 0.13% of 5100 adults in a recent study using magnetic resonance imaging (MRI). 19 However, associated cardiovascular changes, including changes in CIMT, in patients with naturally occurring absence of one carotid artery have not been reported in the literature.…”

Objective: To compare left carotid intima-media thickness (CIMT) and biochemical markers for atherogenesis in neonatal venoarterial extracorporeal membrane oxygenation (ECMO) survivors with normal controls during childhood.Methods: Venoarterial ECMO survivors and healthy patients between 12 and 18 years of age were enrolled in a matched control prospective study. ECMO survivors were matched to controls based on chronological age and percentage of body mass index (BMI). Measured CIMT of the posterior left carotid artery and CIMT values corrected for carotid artery size were used for data analysis.Results: Thirty-one neonatal venoarterial ECMO survivors were matched to 31 healthy controls. No significant differences were found between ECMO survivors and controls for age, weight, percentage of BMI, total fat composition, lipid profiles, ultrasensitive C-reactive protein or homocysteine levels. Significant differences between ECMO and controls patients were found in systolic, diastolic and mean left CIMT. IntroductionExtracorporeal membrane oxygenation (ECMO) is used to treat severe cardiorespiratory failure refractory to conventional medical management. In newborns, ECMO is most commonly used to treat respiratory failure caused by meconium aspiration syndrome, congenital diaphragmatic hernia, sepsis/pneumonia and persistent pulmonary hypertension. Since the inception of ECMO support, the Extracorporeal Life Support Organization (ELSO) registry has documented over 14 000 late preterm and term neonates treated with venoarterial ECMO for respiratory indications, resulting in an overall survival of 73%1 The most common approach to providing ECMO support in neonates is achieved by cannulation of the right common carotid artery (RCCA) and the right internal jugular vein. Most ECMO centers ligate the RCCA at the time of ECMO decannulation. Although no adverse effects are clinically apparent following ECMO support and ligation of the RCCA, these children are dependent on only three arteries (the vertebral arteries and the left carotid artery) to maintain adequate cerebral perfusion. As many of these former neonatal venoarterial ECMO survivors are reaching young adulthood, we set out to investigate whether neonatal ECMO survivors are at an increased risk for premature atherosclerosis and cardiovascular disease (CVD). In adults and older children, carotid artery intima-media thickness (CIMT) is an accepted marker for CVD risks.2 Indeed, in adult populations, when elevated, CIMT is associated with an increased risk for peripheral arterial disease, stroke and coronary events.

“…A recent study analyzed magnetic resonance imaging (MRI) and cerebral digital subtraction angiography (DSA) series and reported higher rates of ICA agenesis or hypoplasia at 0.13% (5). Studies have reported that ICA agenesis is more often seen on the left, and the left/right ratio of the pathology is 3:1 (6). ICA agenesis has been suggested to be a developmental variation, although its exact cause is unknown (7).…”

135Congenital internal carotid artery (ICA) agenesis is a rare abnormality. People with this abnormality usually have adequate collateral circulation and remain asymptomatic for many years. However, patients may also present with pulsatile tinnitus, headache or blurred vision, or rarely with ischemic stroke or subarachnoid hemorrhage. Diagnosis is usually incidental with the performance of carotid artery Doppler ultrasonography or cervical/cranial magnetic resonance imaging owing to other symptoms. ICA agenesis might also be misdiagnosed as ICA occlusion. In this manuscript, we report a patient with ICA agenesis who initially presented with facial paresthesis and was referred to our center for interventional therapy for left-sided ICA occlusion. Keywords: Internal carotid artery, agenesis, occlusionKonjenital internal karotis arteri (ICA, internal carotid artery) agenezisi nadir görülen bir anomalidir. Bu anomaliye sahip hastaların çoğu, yeterli kollateral dolaşım sayesinde uzun zaman asemptomatik olarak kalır. Az sıklıkta hastalar pulsatil tinnitus, baş ağrısı veya bulanık görme gibi yakınmalar ve nadiren iskemik inme ya da subaraknoid kanama tablosu ile başvurabilirler. Tanı genellikle başka bir nedenle yapılmış olan karotis arteri renkli Doppler ultrasonografisi veya servikal/ kranyal manyetik rezonans görüntülemeleri sırasında tesadüfen konur. Ancak dikkatli olunmadığı takdirde ICA tıkanması olarak yanlış bir tanı konulabilir. Bu yazıda, yüzünde yanma şikayeti ile başvuran ve sol ICA tıkanıklığı tanısı ile girişimsel tedavi amacıyla merkezimize yönlendirilen ancak ICA agenezi tanısı konulan bir hasta sunulmaktadır.

“…If the agenesis is detected by MRI angiography, it must be confirmed by CT, in an attempt to find hypoplasia or absence of the carotid canal. Generally, the main secondary source of blood supply is the vertebrobasilar system (in cases of bilateral agenesis) or the dominant ICA (in cases of unilateral agenesis or hypoplasia) (9) .…”

“…This occurs because there is a sufficient cerebral circulation supplied by anastomosis in the circle of Willis, intracavernous and external carotid artery anastomosis, besides persistent embryonal arteries. In these cases, the patients are referred for medical assistance because of complications resulting from abnormalities associated with carotid artery agenesis (7,9) .…”
