Aortic Neck Dilatation Following Thoracic Endovascular Aortic Repair.

Objective: Thoracic endovascular aortic repair (TEVAR) has become a mainstay of treatment for a variety of thoracic aortic pathologies. Expansion of the proximal aortic neck after endovascular repair of abdominal aortic aneurysms has been demonstrated; however, dilatation of the proximal aortic neck after TEVAR has not been well described. We sought to describe remodeling of the proximal neck following TEVAR.

Early experience with arterial thromboembolic complications in patients with COVID-19.

Background: Little is known about the arterial complications and hypercoagulability associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We sought to characterize our experience with arterial thromboembolic complications in patients with hospitalized for coronavirus disease 2019 (COVID-19).

Methods: All patients admitted from March 1 to April 20, 2020, and who underwent carotid, upper, lower and aortoiliac arterial duplex, computed tomography angiogram or magnetic resonance angiography for suspected arterial thrombosis were included.

Risk stratification of indeterminate thyroid fine-needle aspiration biopsy specimens based on mutation analysis.

Background: Mutation analysis is potentially a powerful tool to enhance the diagnostic accuracy of thyroid fine-needle aspiration (FNA) biopsy specimens. However, some clinicians may rely on a negative mutation panel to exclude malignancy. We aimed to determine the malignancy rate in indeterminate lesions with negative mutation analysis.

The impact of incidental identification on the stage at presentation of lower gastrointestinal carcinoids.

Background: Over the past 3 decades, there has been a significant increase in the incidence of gastrointestinal carcinoid tumors in the United States. Incidentally discovered carcinoids in the lower gastrointestinal tract have probably contributed to this increase. In this study we aimed to compare the clinicopathologic characteristics of incidentally discovered carcinoids of the small and large bowel with those identified as a result of symptoms.

Prophylactic central neck dissection and local recurrence in papillary thyroid cancer: a meta-analysis.

Background: The effectiveness of prophylactic central neck dissection (pCND) in the treatment of patients with papillary thyroid carcinoma (PTC) to prevent local recurrence is controversial. We performed a meta-analysis to assess the effect of pCND on local recurrence in PTC.

Methods: Exhaustive search of online search engines identified five retrospective studies that compared the local recurrence rates of PTC in patients without clinically detectable nodal disease in patients undergoing thyroidectomy + pCND (group A) to those undergoing thyroidectomy alone (group B).
