“…A frequent surgical treatment for conditions such as aortic constriction and aneurysms is end-to-end anastomosis [5,23]. Through this treatment, the aorta's blood flow channel is reshaped to enhance heart function and reduce pain.End-to-end anastomosis is one of the recommended treatments for aortic constriction in pediatric patients because of the high degree of flexibility of the aorta.…”

“…In the 1970s, Dr. Steidel and his colleagues first mentioned this disease, which can lead to structural abnormalities of the heart and blood vessels, thereby affecting the normal fun ction of the body [4]. The term "CoA" typically describes a restrict ed constriction of the thoracic descending aorta, which is situated next to the patent ductus arteriosus connection and distal to th e left subclavian artery [5]. This disorder is more common and ca uses 5%-8% of congenital cardiac abnormalities [5].Conversely, IAA denotes a congenital aortic arch deformity wherein the ascendin g and descending aortas do not have a direct physical relationshi p. Unlike CoA, IAA is a real discontinuity phenomeon [6][7][8].…”

The present article provides an overview of the anesthetic pr ocedure employed during off-pump aortic arch interruption surger y, a cardiovascular operation. The case study involved a 54-year-o ld male patient who was diagnosed with aortic arch interruption and who underwent an off-pump surgical intervention. Anesthesia protocol: The patient fasted and abstained before surgery. In the operating room, anesthesia induction was achieve d using midazolam, esketamine, etomidate, sufentanil, and rocuro nium. Throughout the procedure, anesthesia was maintained using propofol, remifentanil, and sevoflurane, with dosage adjustments made in accordance with the progress of the surgical interventio n. Intraoperative monitoring: Conventional monitoring included E CG, blood pressure, pulse oxygen saturation, end-tidal CO2, bispec tral index, hemodynamic monitoring, and cerebral oxygen saturati on monitoring (rSO2). The patient's mean arterial pressure (MAP) was carefully regulated within the range of 60-80 mmHg, while t he heart rate was maintained between 50-90 beats per minute t o ensure a stable circulatory state. Anesthesia outcome: The patient's vital signs remained stable, with appropriate anesthesia depth. The surgery was successfully completed, and the patient was transferred to the critical care u nit for postoperative observation and treatment. In off-pump aortic arch interruption surgery, maintaining stabl e vital signs and ensuring stable circulation are crucial anesthetic management components. The reported case demonstrated a satis factory anesthesia effect with no significant complications. This ca se highlights the importance of employing reasonable anesthesia methods and monitoring measures for safe and effective patient care.

“…Coarctation of the aorta (CoA) occurs in 0.3 of every 1,000 live births (1) and makes up 5%-8% of all congenital heart diseases (2). It is likely to represent a spectrum of aortic narrowing from a discrete entity to tubular hypoplasia, with many variations seen between the two extremes (3).…”

“…The main pathophysiological change of CoA is hypertension proximal to coarctation, and the postulated mechanisms of hypertension are mechanical obstruction and renin-angiotensinmediated humoral mechanisms (2). The increased afterload of the left ventricle will cause left ventricular hypertrophy.…”

ObjectivesBy reviewing the diagnostic process for adolescents with coarctation of the aorta (CoA) in our institution, we analyzed the reasons for delayed diagnosis of CoA. We also proposed a diagnostic protocol to improve the detection rate of CoA.MethodsIn this retrospective study, we included 48 patients aged 12–18 years who were diagnosed with CoA in our hospital from January 2000 to November 2022. Clinical data from involved cases in local hospitals and our institution were collected.ResultsAll patients had blood pressure (BP) measurements in upper and lower extremities in our institution. They all had hypertension, 29 (60.4%) of whom had known histories of the same. BP in the upper limbs of 47 (97.9%) patients was ≥20 mmHg higher than that in the lower limbs, and BP in the upper limb of 1 (2.1%) patient was greater than 0 and less than 20 mmHg than that in the lower limb. Echocardiography (ECHO) was performed in all patients, computed tomography (CT) or magnetic resonance imaging (MRI) was performed in 44 patients (91.7%). There were 38 (79.2%) patients who visited local hospitals. Among them, a total of 20 (52.6%) patients had their right upper extremity BP measured, 18 (47.4%) only had their left upper extremity BP measured, and 16 (42.1%) had their lower extremity BP measured. ECHO was performed in 27 (56.2%) patients and CT/MRI was performed in 18 (37.5%) patients. The detection rate for CT/MRI was 100%, and those of ECHO were 72.9% and 18.5% at our institution and a local hospital, respectively. Forty-eight (100%) and 23 (60.5%) patients were detected in our institution and local hospitals (P < 0.0001).ConclusionWe recommend measuring BP in the bilateral upper extremities. Measurement of BP in the lower extremities is recommended if hypertension is diagnosed. MRI/CT is recommended when BP in the upper extremity is greater than that in the lower extremity.
