Vascular causes of lower extremity wounds
Author: Niazi Khusrow
The two most common causes for lower extremity wounds are arterial and venous insufficiency. Arterial insufficiency is encountered with advancing age, diabetes mellitus, chronic kidney disease, coronary artery disease, hypertension and dyslipidemia. Patients can increase the risk if they indulge in tobacco products. Chronic venous insufficiency is far more common than arterial and starts at an earlier age especially if there is family history. It is exacerbated in professions where prolonged standing is involved. Both these conditions can be quickly diagnosed with simple tests which can then lead to proper treatment. By diagnosing these conditions promptly, we may help our patients and may reduce the epidemic of lower limb amputations.
When and how to do chemical ablation with Varithena
Author: Niazi Khusrow
Chronic venous insufficiency causing significant symptoms necessitates treatment, with one of the modalities being chemical ablation. In our experience we have found this form of treatment very helpful in tortuous superficial veins which would be hard to treat with stiff catheters like LASER or Radiofrequency. Before doing the chemical ablation it is essential to identify and mark the perforators to avoid any chemical transiting into the deep venous system and resulting in deep venous thrombosis.
Dr. Niazi is board certified in Internal Medicine, Cardiovascular Diseases and Interventional Cardiology by the American Board of Internal Medicine. He has had extensive experience working in some of the leading institutions of the world including USA over the past 25 years. He joined Emory University in 2003. Besides his interventional cardiology skills he brought many innovations to Emory. To high light a few:
1. Built a nationally recognized peripheral vascular program
2. Initiated a peripheral research program in cardiology
3. Established a noninvasive vascular laboratory
4. Started the first cardiology-run clinic for chronic venous insufficiency in Georgia. He is one of the few cardiologists who treat venous disease along with arterial disease
5. Educated and trained physicians especially cardiologists in how to look for vascular disease outside the heart including carotid artery disease peripheral arterial disease and lower extremity venous disease
6. Active industry consultant and researcher, participated in more than 20 clinical research studies and has authored more than 15 clinical articles in peer-reviewed medical journals
7. Leader in helping patients especially with non-healing wounds to avoid them from having amputations
Besides training physicians in the non-invasive Doppler techniques for the diagnosis of vascular diseases and complex interventional procedures, he actively participates in helping companies develop new devices for endovascular procedures.
Dr. Niazi is a prolific teacher and besides teaching medical students, residents and cardiology fellows, he has been invited to give lectures, grand rounds locally, nationally and internationally. He has travelled to many countries and has encouraged physicians to not only think of coronary artery disease but also evaluate and treat patients for vascular disease. He has done live demonstration cases demonstrating various endovascular techniques in different countries.
He is also a member of the peripheral vascular disease council of the prestigious American College of Cardiology (ACC) and has helped the college in growing the awareness of PVD. He is also member of the ACC Competency Management Committee. He continues to share his experience with other physicians in advancing the field of cardiovascular diseases.
