Integrated vascular surgery residency to thoracic surgery fellowship: A less-known training pathway for modern cardiothoracic surgery

To the Editor:

The recent article by Ahmed and colleagues¹ provides a comprehensive review of the various pathways available to achieve board certification in thoracic surgery. One such pathway highlighted is the integrated vascular surgery program followed by a traditional thoracic surgery fellowship, which represents a 7- to 8-year trajectory. This pathway, although less commonly pursued, has an advantage of providing dual board certification in vascular and cardiothoracic surgical subspecialities. The attainment of board certification in vascular surgery is a valuable asset, although it remains underrepresented in medical student advising. Many students are unlikely to encounter or receive guidance from surgeons who have completed this specific pathway, thereby limiting awareness of its advantages.

The integrated vascular surgery program emphasizes the development of fundamental vascular surgical skills, including vascular access and anastomosis. These technical competencies form the cornerstone of cardiac surgery.² Early exposure to endovascular techniques in aortic surgery during vascular training facilitates the mastery of large-bore percutaneous arteriovenous access, which is critical for many cardiac procedures. The training process often follows a natural progression, where expertise in complex vascular territories—such as the femoral, carotid, brachial, and tibial arteries—culminates in proficiency in coronary surgery. Graduates of vascular surgery programs enter cardiothoracic fellowships well prepared for coronary revascularization, open and endovascular thoracic aortic procedures, transcatheter valve interventions, and peripheral vascular access. These skills are highly valued among cardiothoracic trainees (Table 1).

Advantages and disadvantages of integrated vascular to traditional cardiothoracic fellowship training paradigm

Advantage

Disadvantage

-Dual board certification in vascular and cardiothoracic surgery -Community-based general practice desirability -Superior “wire” skill set -Comfort in performing endovascular and open aortic surgery, extra-anatomical reconstruction, and peripheral cardiopulmonary cannulation -Management of concomitant comorbidities, such as carotid, peripheral vascular, and end stage renal disease -Broad referral based -Flexibility to pivot careers

-Lack of exposure to minimally invasive general surgery -Less desirable in highly academic referral centers with robust subspecialized work pool -Potential perception as jack of all trades, master of none

The demand for surgeons with broad, versatile skillsets is particularly high in community hospital settings, where financial pressures and operative volume are key considerations. Surgeons who provide services across multiple subspecialties offer significant financial advantages, creating wide referral bases and optimizing surgical volume for lower-volume hospital systems.

However, this dual certification pathway is not without its challenges. In large academic centers, where vascular and cardiothoracic departments often function independently, the ability to navigate between these 2 specialties can present hiring challenges. The division between these departments may limit opportunities for surgeons seeking to practice in both domains.

Despite these obstacles, the versatility afforded by dual certification remains its greatest advantage. In community-based settings, the ability to perform both vascular and cardiothoracic procedures offers a significant professional benefit. For individuals in integrated vascular surgery programs who are considering a subsequent cardiothoracic fellowship, pursuing this path is highly recommended. The expansion of surgical expertise and the ability to bridge multiple specialties provides both personal and professional fulfillment. Ultimately, a strong foundation in vascular surgery enhances one's capabilities as a cardiac surgeon, and vice versa. Regardless of the path chosen, a commitment to quality and lifelong learning will continue to define modern cardiothoracic surgeons.
