Background: Bentall surgery is the main method for treating aortic root lesions, but traditional Bentall method is very difficult for patients with mild aortic sinus dilation to directly anastomose the coronary artery orifice with graft. Case presentation: A 41-year-old man was admitted to hospital after severe chest pain. Computed tomography angiography(CTA)revealed a type A aortic dissection. Echocardiography showed moderate aortic valve regurgitation and an aortic sinus diameter of 38 mm(mm). The patient underwent emergency Bentall surgery (using a preset coronary artery orifice patch), total arch replacement, and implantation of a graft into the descending aorta. Follow-up echocardiography showed the patient cardiac function was good, and there was no residual leakage at the coronary artery orifice. Conclusions: This method is an alternative to traditional Bentall surgery and is suitable for all aortic root lesions, especially those with mild aortic sinus dilation or concomitant aortic dissection.

Key Clinical Message: After a Bentall surgery, there is a small chance of developing a serious complication called vascular graft infection. 18F‐FDG PET/CT, a new and accurate diagnostic tool, can help detect it early, especially if the symptoms are unusual. A 14‐year‐old boy who had undergone Bentall surgery 1 year prior presented with symptoms of fever, chills, loss of appetite, and weight loss over the course of a month. The initial Bentall surgery was performed due to an aneurysm of the thoracic aorta, along with severe aortic valve insufficiency and moderate aortic valve stenosis. The patient was referred to the PET/CT department for evaluation of possible endarteritis or infection of Dacron graft, which had been reported in trans‐esophageal echocardiography as suspicious findings. Despite normal blood tests, blood cultures, and other imaging modalities, the 18F‐FDG PET/CT confirmed the diagnosis of vascular graft infection. This diagnostic tool allowed for timely and appropriate treatment and prevention of possible complications. [ABSTRACT FROM AUTHOR]

Background: Aortic pseudoaneurysm is an infrequent complication of ascending aorta surgery. Cases: This is a report of two cases that underwent the Bentall procedure that presented with large pseudoaneurysms. Conclusion: Use of multimodality imaging after Bentall surgery has been advocated for the detection of surgical complications. Although 3D CT angiography has the highest diagnostic accuracy, familiarity with transthoracic echocardiographic finding in these patients will lead to earlier diagnosis. [ABSTRACT FROM AUTHOR]
