Insights
Medical compression stockings (TED) are more effective than elastic bandages in preventing leg edema after coronary artery bypass graft (CABG) surgery. This compression therapy helps reduce swelling in the foot and heel regions of donor limbs.
Area of Science:
- Vascular Surgery
- Postoperative Care
- Edema Management
Background:
- Saphenous vein removal during coronary artery bypass graft (CABG) surgery can lead to postoperative leg edema.
- Compression therapy is a common method to prevent and manage such swelling.
Purpose of the Study:
- To compare the effectiveness of medical compression stockings (TED) versus elastic bandages in preventing edema in donor limbs after CABG surgery.
Main Methods:
- Measurements of lower limb peripheries were taken at four regions (foot, heel, ankle, calf) in 295 CABG patients upon admission and at discharge.
- The difference in measurements between admission and discharge was used to assess the efficacy of compression methods.
Main Results:
- Patients using TED stockings showed significantly less peripheral swelling in the foot (region A) and heel (region H) areas at discharge compared to those using elastic bandages.
- Statistical analysis indicated significant differences in regions A (P=0.009) and H (P=0.012) favoring TED stockings.
Conclusions:
- Knee-length medical compression stockings (TED stockings) are more effective in reducing foot and heel edema in donor limbs post-CABG than traditional elastic bandages.
- TED stockings offer superior edema control in specific lower limb regions following saphenous vein harvesting for CABG.
Abstract:
The removal of the saphenous veins in coronary artery bypass graft (CABG) surgery may cause leg edema. Compression therapy is often used to prevent postoperative edema. The objective of this study was to compare the efficacy of medical compression stocking (TED) and elastic bandage-type on donor limbs after CABG. The peripheries of lower limbs were measured at four regions (A: end of tarsal bones, H: heel , B: immediately above the ankle, C: largest circumference of the calf) at admission in 295 patients how CABG candidates and differences in these measurement points at discharge compared to measurements at admission time were calculated. The difference was considered as a measure of the effectiveness of two types of compression to prevent postoperative edema in donor limbs after CABG. The alterations of 396 donor limbs of 295 patients were examined after CABG at admission and discharge time. In 101 patients veins for graft were taken from both lower limbs. After analysis, if subjects had worn TED stockings, the peripheries of donor limbs at discharge were less than at admission time in the A and H regions compared to elastic bandage group (P(A) = 0/009), (P(H) = 0/012). The conclusion reached was that using the kind of knee length compression stocking (TED stocking , Kendall Co.) is more effective edema at foot and heel regions in donor limbs after CABG than elastic bandages.
