CARDIOVASCULAR JOURNAL OF AFRICA • SMC-PAFCIC Abstracts October 2022 71 AFRICA Submission ID: 1573 PARAORTIC ECTOPIC THYROID: A CASE REPORT NCIRI SALMA, BOUSNINA MOUNA, SOUMER KHEDIJA, AZABOU NADIA, BENNOUR EMNA, JEMEL AMINE TUNISIA Background: Ectopic thyroid is defined as thyroid tissue not located anterolaterally between the second and the fourth tracheal cartilage. This anomalous localization is a rare lesion that results from abnormal embryologic development and/or migration of the gland. An intracardiac ectopic location is even rarer. We are presenting a case of a discovery of paraortic ectopic thyroid during coronary artery bypass graft surgery. Case report: A 63 year old female patient with a history of diabetes and dyslipidemia who got admitted in cardiovascular surgery department for coronary revascularization. During the coronary artery bypass graft surgery, we discover a 25mm superficial movable mass on the antero-lateral side of the ascending aorta. The mass was resected and sent to anatomopathology to clarify the diagnosis. Thus, the pathological examination of the mass revealed ectopic thyroid cells with no signs of malignancy. Howerver, the patient was clinically and biochemically euthyroid. Ultrasound sonography of the cervical region showed no thyroid gland abnormalities. We completed the explorations with scintigraphy that showed a thyroid gland in place, decreased in size, and no residual ectopic thyroid tissue. With simple postoperative follow-up, the patient was sent home and had regular check-up revealing the absence of any clinical complication. Conclusion: The clinical occurrence of ectopic thyroid gland is an infrequently encountered condition, resulting from a developmental abnormality during the migration of the thyroid. Intracardiac or pericardial extension is a rarer case that could be discovered incidentally. This condition is often asymptomatic, whereas symptoms could be related to ectopic thyroid size, to its relationships with surrounding organs. Submission ID: 1578 AXILLARY ARTERY ANEURYSM REVEALED BY ACUTE ISCHEMIA OF THE UPPER EXTREMITY CHIHAOUI CHAIMA, SOUMER KHEDIJA, BOUSNINA MOUNA, JABER CHAKER, BENNOUR EMNA, JEMEL AMINE TUNISIA Background: Upper extremity peripheric artery aneurysms are not common. True aneurysms of the axillary artery on the basis of atherosclerosis are rare and remain asymptomatic until a complication occurs. We are reporting a case of left axillary artery aneurysm revealed by acute ischemia of the upper extremity. Case report: A 92-year-old male patient presented to the emergency department with the complaint of an increasing pain and numbness of his left forearm, associated with cyanosis of the tips of fingers of the left hand evolving since the day before. He had no history of trauma or vascular intervention. But he was hypertensive and receiving oral anticoagulation therapy due to chronic atrial fibrillation. There was no axillary mass in the physical examination. However, humeral, ulnar and radial pulses were suppressed and the neurological examination of the upper extremity showed paresthesia of fingers. CT scan objectified a fusiform aneurysm, partially thrombosed and measuring 4 * 4 cm of the left axillary artery. The distal arteries were not contrasted. We immediately started intravenous heparin and urgent open surgical resection of the aneurysm was planned. Under general anesthesia and through an infraclavicular incision, we controlled the axillary artery upstream the aneurysm then the brachial artery after brachial approach. The aneurysmal mass was carefully dissected, separated from the surrounding tissues and resected after heparinization and clamping. Embolectomy of distal arteries using a Fogarty balloon catheter was also performed. Arterial continuity was established by interposing a graft bypass. Distal and proximal anastomosis were done in end to side fashion. Distal pulses were normal after the anastomosis. The pathological examination of the aneurysm sac revealed a true axillary artery aneurysm on an atherosclerosis basis. Postoperative course was uneventful and the patient was discharged on the third postoperative day without morbidity. Conclusion: Although aneurysms of the axillary artery are rare and mostly asymptomatic, it should be treated early to prevent many complications such as distal embolization. Thus, surgical or endovascular repair, if suitable anatomy, should be done without delay.

Left atrial (LA) longitudinal was reported recently to have additive diagnostic value to assess left ventricle(LV) filling pressures (LVFP)in acute settings Our study aim is to assess the accuracy of LA strain inevaluating
