Multispecialty involvement in the management of type B aortic dissections in the endovascular era-Implications for training cardiothoracic residents.

PURPOSE

Involvement of qualified specialists with proficiency in endovascular therapies has created flux regarding the role of cardiothoracic surgeons, vascular surgeons, and other catheter-skilled specialists in the management of type B aortic dissections. We used manuscript authorship trends and recent match data in order to study how multi-specialty involvement in treating aortic dissections has changed in the endovascular era.

METHODS

A PubMed review of published literature between 1998 and 2015 was performed with "aortic dissection" in the title. Case studies and entries with incomplete author or identifying information were excluded. Author number, specialty affiliation, and treatment focus were recorded. Available residency match data were obtained from the National Resident Matching Program (NRMP).

RESULTS

Cardiothoracic surgeons represented 38.5% (10/23) of the authors for papers with an endovascular focus in 1998 compared with 27.7% (59/213) in 2015. Vascular surgeons represented 19.2% (5/23) and 37.1% (79/213) of authors in 1998 and 2015, respectively. Radiologists accounted for 30.4% (7/23) of authorship in 1998 and 8.9% (19/213) in 2015. NRMP match data revealed a 10.6% decrease in thoracic surgery matches from 2004 to 2015, while vascular surgery and interventional radiology increased by 74.7% and 191.1%, respectively.

CONCLUSIONS

Endovascular technologies have resulted in significant changes as to which specialties manage complicated type B aortic dissections. Vascular surgeons, with both open and extensive endovascular training are optimally positioned to assume a major role in the care of aortic dissection patients. Continued emphasis on endovascular training and multispecialty collaboration is essential for cardiothoracic surgeons in the endovascular era.
