Summary
Vascular surgery in patients with human immunodeficiency virus (HIV) is safe and effective. Surgical outcomes are improved with necessary precautions, and antiretroviral therapy can enhance patient immune status.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Immunology
Background:
- Vascular disease is a significant concern in patients with human immunodeficiency virus (HIV).
- Understanding the spectrum of vascular disease and associated risk factors in HIV patients is crucial for effective management.
Purpose of the Study:
- To determine the spectrum of vascular disease in HIV/AIDS patients.
- To identify risk factors influencing clinical outcomes.
- To develop a management protocol for vascular disease in HIV-positive individuals.
Main Methods:
- Prospective clinical survey with comprehensive screening for vascular disease risk factors and HIV-related conditions.
- Management of vascular emergencies irrespective of HIV status.
- Elective management based on immune status and risk stratification.
Main Results:
- 42 HIV-positive patients were studied, with occlusive disease (57%) being the most common presentation.
- Vascular surgical procedures were performed on 36 patients with no surgical mortality.
- Complications included 2 amputations and 7 cases of minor wound sepsis; 3 patients on antiretroviral therapy showed improved viral load and CD4 T-cell counts.
Conclusions:
- Surgical intervention for vascular disease in HIV-positive patients can be safe and effective.
- Implementing necessary precautions can reduce surgical morbidity.
- Antiretroviral therapy may positively impact immune status in patients undergoing vascular surgery.
