Clinic’s Vascular Specialists Provide Circulatory Care, Limb Preservation to Patients

Hattiesburg Clinic Vascular Specialists offers comprehensive medical, endovascular and surgical care for all circulatory issues outside of the heart and the intracranial vessels. They specialize in the care of arterial and venous systems, from the carotids down to the toes, and to the top of the aortic arch.

The department’s services include medical management; surveillance programs; diagnostic vascular ultrasound; diagnostic arteriography; endovascular angioplasties; atherectomies and stent placement; surgical bypass procedures; and hybrid vascular reconstruction, which is a unique combination of open and endovascular surgery within the same procedure.

Vascular Specialists is led by four physicians: Humayun Bakhtawar, MD, RPVI; Edgar Guzman, MD, FACS, RPVI; Lewis E. Hatten, MD, FACS, RPVI; and J. Keith Thompson, DO, FACOS, RVT, along with a physician assistant, Samantha L. Jones, PA-C. All four physicians are fellowship-trained exclusively in the treatment of vascular issues.

Some providers in the department are qualified to supervise hyperbaric oxygen (HBO) chamber dives at the Forrest General Hospital Wound Care Center, with the goal of limb preservation. One provider offers a quarterly lecture and vascular screenings for the “Dare to Care” series at FGH. Another provider participates annually in medical missions in medically underserved countries. Several providers have also served as clinical faculty for William Carey’s Medical School and the USM Nursing program.

The rest of the team consists of four vascular sonographers, nine endovascular nurses and techs, and 12 office nurses and support staff. The department has plans to add more providers in the future.

In 2016, Vascular Specialists opened South Mississippi’s first physician-led outpatient angiography suite. The office-based Endovascular Center offers catheter-based diagnostics and interventions on the second floor of the main clinic, focusing on a patient-centered approach to care.

The department’s primary office, along with its Endovascular Center and Vascular Ultrasound Lab, are on the second floor of Hattiesburg Clinic’s main facility, 415 S. 28th Avenue in Hattiesburg. The specialists also hold outreach clinics in Collins, Columbia, Laurel, Picayune and Wiggins. Additionally, they see patients in conjunction with the wound care clinics in Tylertown and the FGH Wound Care Center.

Their office hours are Monday through Friday, 8 a.m. to 5 p.m. The department can be reached at 601-579-5010. To learn more about Vascular Specialists’ services and providers, visit
