Two mechanical ways to promote venous return
When thromboprophylaxis comes up, many people first think of the classic anti-embolism stocking. Medical thromboprophylaxis stockings have been established for decades and are widely known. Less well known is the second mechanical option: the compression garment used with intermittent pneumatic compression (IPC). Both pursue the same goal — to promote venous return and counteract a stasis of blood in the deep veins — by different means.
The compression stocking: constant, static pressure
A medical thromboprophylaxis stocking applies a continuous, graduated pressure to the leg — strongest at the ankle, decreasing proximally. The pressure is static: it acts as long as the stocking is worn and does not change actively. Stockings are simple to apply, require no device and are inexpensive. Their effect depends on the correct size and fit.
The compression garment: active, cyclic compression
A compression garment is filled with air pressure in cycles by an IPC device and then released, typically about once per minute. With sequential garments, several air chambers fill one after another from distal to proximal in a graduated pressure gradient, moving the blood in a directed way towards the body. This active, rhythmic mechanism mimics the muscle pump and is especially relevant for immobilised patients whose own calf pump is inactive.
Side by side
| Feature | Compression stocking | Compression garment (IPC) |
|---|---|---|
| Mode of action | static continuous pressure | active, cyclic compression |
| Drive | passive (tissue elasticity) | device-supported (air pressure) |
| Promotion of return | continuous, passive | rhythmic, directed (distal → proximal) |
| Effect on coagulation | none (mechanical) | none (mechanical) |
| Typical strength | simple, device-free, inexpensive | active even with full immobility |
| Guideline framing | recognised mechanical prophylaxis | anchored in the S3 guideline (AWMF 003-001) |
Both procedures are recognised measures of mechanical thromboprophylaxis. The table compares modes of action and is not a judgement in the individual case. Which measure or combination is suitable is decided by the treating professionals.
Which measure when?
The choice depends on indication, risk profile and contraindications. IPC with compression garments is a sensible option in particular when an active promotion of venous return is desired — for example in heavily immobilised patients — or when stockings are not suitable. In high-risk settings, mechanical and pharmacological measures may be combined following a risk assessment. Read more about the mode of action on the page on intermittent pneumatic compression.
The compression garment from UniCare
UniCare supplies the IPC compression garments of the Phlebo Press® technology together with the matching devices — the mobile Phlebo Press® DVT 650 Easy and the Phlebo Press® DVT 603 for leg and foot indications — including German service, device instruction under §83 MPBetreibV and guaranteed availability from the warehouse in Hesse.
Frequently asked questions
What is the difference between a compression stocking and a compression garment (cuff)?
A medical anti-embolism / thromboprophylaxis stocking applies a constant, static pressure to the leg. A compression garment used with intermittent pneumatic compression (IPC) works actively: it is filled with air pressure in cycles by the device and then released, promoting venous return rhythmically. Both belong to mechanical thromboprophylaxis; the stocking acts passively and continuously, the garment actively and cyclically.
Is the IPC compression garment better than a thromboprophylaxis stocking?
There is no blanket answer, and claiming one would be unsound. Stockings and IPC have different modes of action and areas of use. IPC is an active, device-supported measure anchored in the German S3 guideline on VTE prophylaxis (AWMF 003-001); medical thromboprophylaxis stockings are also a recognised measure. Which measure or combination is suitable is decided by the treating professionals based on indication, risk profile and contraindications.
What is the alternative to anti-embolism stockings in the hospital?
As a mechanical alternative or addition to the stocking, intermittent pneumatic compression (IPC) with compression garments is an option. It is particularly suitable when active promotion of venous return is desired or when stockings are not an option. UniCare supplies the Phlebo Press® systems for this, with German service.
When is the compression garment used?
Typical settings are the postoperative phase, immobilised patients in intensive care, situations with a contraindication to pharmacological prophylaxis, and adjunctive use in high-risk settings. The indication is determined by the treating professionals.
