Median arcuate ligament syndrome, also known as celiac artery compression syndrome, is a rare and unusual clinical disorder. Its symptoms are non-specific, which complicates its diagnosis, and a multidisciplinary approach is required to treat the disorder. The ligament is circumferentially cleared by laparoscopy. Selective angiography and endovascular techniques may be used after laparoscopy. Vital organs and important vascular structures can be injured during the surgery. The combination of different procedures, as well as the high risk of damage, make this process a significant challenge for the anaesthetist. During corrective surgery for median arcuate ligament syndrome, general anaesthesia must be adapted to the various haemodynamic and ventilatory requirements, and strict control of pain established, as oral tolerance is a key factor in the post-operative recovery of these patients., (Copyright © 2018 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

Objective: Intraoperative transesophageal echocardiography can be a highly useful monitoring technique during myocardial revascularization surgery when extracorporeal circulation (ECC) is not being used. Transesophageal echocardiography provides real-time images on both volume status and segmental myocardial contractility without interfering with the surgical field., Patients and Methods: A total of 25 patients undergoing myocardial revascularization by sternotomy without ECC were monitored by transesophageal echocardiography during surgery., Results: The 18 men and 7 women studied had a mean (SD) age of 71.3 (8) years. A third of them had hypertension and diabetes, 3 had suffered a cerebrovascular accident, and 2 had renal failure. Nine patients had a history of acute myocardial infarction and 3 had undergone angioplasty. Baseline echocardiograms on all patients established that 6 had a low ejection fraction (<30%). Twelve had altered segmental contractility, which was transient in 11 cases. Six patients had improved ejection fraction at the final assessment. Transesophageal electrocardiography also monitored volume status and the effects of inotropic drugs and beta-blockers in 83% of the patients., Conclusion: Transesophageal electrocardiography is a minimally invasive, safe, and precise way to directly monitor the beating heart in real time during myocardial revascularization without ECC. Image quality is good.

We describe the case of a 70-year-old man who underwent resection of a right hypernephroma with vena caval and right atrial extension with continuous monitoring by transesophageal echocardiography. The monitoring technique brought important advantages, providing images that facilitated anatomical and functional evaluation of cardiac structures without obstructing the surgical field. Images of the heart and great vessels obtained in real time allowed the surgeon to make operative decisions based on accurate assessment of the cephalad extension of the tumor to the right chambers. Transesophageal echocardiography also allowed the anesthesiologist to monitor hemodynamic status throughout surgery and watch for tumoral emboli. The imaging technique proved to be highly useful for both anesthetic and surgical management of the patient.
