Anterior Spine Exposure

Anterior spine exposure is the vascular surgeonโ€™s role in anterior lumbar interbody fusion: safely mobilizing the aorta, vena cava, and iliac vessels so the spine surgeon can reach the disc space, then closing the approach. Vascular Wellness Institute provides exposure for spine and orthopedic surgeons at hospitals in Sarasota, Bradenton, and Lakewood Ranch.

Anterior Spine Exposure in Sarasota & Bradenton

Spine Surgery at the Front Requires a Vascular Surgeon You Can Trust Behind It.

Anterior lumbar interbody fusion (ALIF) is a spine surgery technique that approaches the lumbar discs from the front of the body rather than from the back. This approach gives spine surgeons better access to the disc space and allows larger, more stable implants to be placed. However, gaining access to the front of the lumbar spine requires careful dissection around the major blood vessels โ€” the aorta, the inferior vena cava, and their branches โ€” that run directly in front of the spine.

This is the vascular surgeon’s role in ALIF: to safely mobilize and retract the major abdominal vessels, exposing the disc level the spine surgeon needs to access, and then to close the exposure at the end of the case. Vascular Wellness Institute provides anterior spine exposure services in Sarasota and Bradenton, working directly with spine surgeons and orthopedic surgical teams.

Why a Vascular Surgeon?

The proximity of the aorta, vena cava, and iliac vessels to the anterior lumbar spine means that inadvertent vascular injury during anterior approach spine surgery can cause life-threatening hemorrhage. Using a vascular surgeon to perform the exposure โ€” rather than having the spine surgeon perform their own approach โ€” is the standard of care at high-volume spine centers. The vascular surgeon is trained to work safely around these vessels, to recognize and control bleeding if it occurs, and to repair any vascular injury.

For Spine Surgeons and Referring Physicians

If you are a spine surgeon or orthopedic surgeon planning an anterior lumbar procedure in the Sarasota-Bradenton area and need a reliable vascular surgery partner for exposure, we welcome the opportunity to discuss your cases. Dr. Kristian Ulloa and Dr. Mariano Arosemena have experience with anterior spine exposure and work collaboratively with surgical teams at HCA Florida Blake Hospital, HCA Florida Sarasota Doctors Hospital, and Lakewood Ranch Medical Center.

To discuss a case or schedule a collaborative procedure, please contact us through the Physician Referrals link or call either of our offices directly.

Frequently Asked Questions

  • What levels of the lumbar spine can be accessed anteriorly? +

    The most commonly accessed level for ALIF is L5-S1, which is approached through a retroperitoneal or transperitoneal dissection below the bifurcation of the aorta and vena cava. L4-5 and occasionally higher levels can also be accessed anteriorly, though the vessel anatomy at these levels is more complex. Preoperative CT angiography helps plan the approach.

  • Are there risks specific to the anterior approach related to the vascular exposure? +

    The primary vascular risks are injury to the aorta, vena cava, or iliac vessels during exposure or closure, and injury to the superior hypogastric plexus โ€” a nerve network at L5-S1 that, if damaged, can cause retrograde ejaculation in male patients. An experienced vascular surgeon minimizes both risks. Preoperative counseling for male patients regarding this specific risk is standard.

  • How long does the exposure portion of the case take? +

    In experienced hands, anterior spine exposure typically adds 30 to 60 minutes to the operative time, depending on the level being accessed, the patient's body habitus, and the presence of prior abdominal surgery or scarring. Closure adds additional time.

  • Can anterior spine exposure be performed if a patient has had prior abdominal surgery? +

    Prior abdominal surgery increases the complexity of anterior spine exposure due to adhesions, but is not an absolute contraindication. A careful review of the patient's surgical history and abdominal imaging is warranted. Your vascular surgeon will assess feasibility and discuss any additional risks.

  • How do I refer a patient for anterior spine exposure? +

    Spine surgeons can reach us through the Physician Referrals link on our website, or by calling either office directly. We prefer to speak with the spine surgeon prior to scheduling to review the case, confirm hospital privileges, and coordinate scheduling.
