Natural history of visceral branch artery dissections and the influence of concurrent aortic dissection on overall and intervention-free survival.

Objective: Visceral branch artery dissection (VBAD) is uncommon and may occur with or without an associated aortic dissection (AD). We hypothesized that isolated VBAD would have a more benign clinical course than those with concurrent AD and compared survival outcomes stratified based on aortic involvement.

Methods: VBAD over a 5-year period were identified using International Classification of Diseases codes.

Translation of Legislation: Effect Analysis of Michigan Opioid Law on Clinical Practice.

Background: To combat almost 450,000 Americans dying of opioid overdose between 1999 and 2018, the Michigan Opioid Laws were implemented on July 1, 2018, to reduce overprescription of opioids. This retrospective study evaluated the effect of this legislation on prescribing patterns after thoracic operations at an academic, tertiary care center.

Method: Charts of 776 patients undergoing lobectomy, paraesophageal hiatal hernia repair, Nissen fundoplication, or esophagectomy between July 1, 2017, and July 1, 2019, were reviewed.
