Next, a pressure dressing and thrombo embolic deterrent (TED) -above knee stockings- were applied to the donor limbs. Twenty-four hours later, the initial dressings were removed in the ICU, and the wounds were cleaned and sterile dressings were applied again. In routine clinical practice, elastic bandages were applied over the sterile dressing on the donor limbs immediately after the surgery. The anatomical locations of the vessels taken for graft depend on the vein size and patient's characteristics. Techniques used to remove saphenous vein were called the open-surgical-incision direct approach. Also, the patients who suffered from extreme generalized edema (anasarca) before or after surgery (due to different reasons such as heart failure, transient nephropathies and DVTs) and the cases on high dose of diuretics (because of significant heart failure) were excluded from the study. In the next step, by preoperative methods like physical examination or duplex ultrasound report, patients with deep vein thrombosis (DVT), varicose veins and lymphadenopathy were excluded. diuretics) of the patients were collected using questionnaire method. diabetes mellitus) and drug history (e.g. Demographic data, including age, gender, height, weight, medical history (e.g. They were scheduled for elective CABG surgery at Rajaie Cardiovascular Medical and Research Center, Tehran, Iran from February 2011 to January 2012, and written informed consent was obtained from each participant. One-hundred patients (79 men and 21 women, with mean age of 60 ± 9 years), were enrolled in this prospective cohort study. However, few studies have been conducted to evaluate the beneficial effects of elastic stockings on the prevention and treatment of lower limb edema in Iran ( 16).Īfter the approval of the study, the protocol was granted by the institutional review board. As a result, one of the most important approaches for suppressing lower limb edema after CABG surgery is compression therapy with medical elastic compression stockings. Based on the previous studies, the medical elastic compression stocking is one of the most frequent used medical compression techniques during prophylactic and maintenance phase of lower limb edema due to its ease of use and therapeutic function ( 15). Compression improves venous return of the lower extremities and therefore speeds-up the healing process ( 14). This technique suppresses postoperative pain and edema by preventing the formation of hematomas along the course of the removed vein.
Edema is a well-known complication in patients following CABG surgery and may cause discomforts in the donor legs, such as numbness, weakness, immobilization, sleep disorder and delayed healing ( 10- 12).Ĭompression therapy is the most common intervention to treat venous and lymphatic vessels disorders ( 13). There are different complications at the operation site, including, edema, erythema, tenderness and infection ( 6- 9). Besides arterial grafts, removal of the saphenous leg veins is the most common procedure in CABG ( 3- 5). This procedure is performed by harvesting saphenous vein or radial artery.
The number of coronary artery bypass graft (CABG) surgeries has been increased recently and it is estimated to be 800,000 surgeries worldwide annually ( 2).
Coronary artery disease is a global epidemic and the most common cause of death among non-infectious diseases ( 1).
