Distal outpatients hemodynamic treatment of chronic venous insufficiency of the lower limbs: a new proposal

Ann Ital Chir. 2023:94:549-556.

Abstract

The etiology of the venous insufficiency of the lower limbs is related to the increase of the district pressure. This occurs in case of pressure overload of the afferent compartment with a progressive increase of the gradient until the reversal of the flow direction. Varicose veins would be the effect and not the cause of the pressure overload which must always be researched in the efferent (draining) compartment. The gradient inversion in a compartment causes a reflux circuit (venous shunt) only if - in addition to the escape point - one re-entry point is also active, The closure of the escape point does not solve the etiological moment of the district pressure overload. It is therefore a symptomatic treatment that cannot reduce the potential of the system to cause recurrences. During walking, reflux will cause Transmural Pressure Peaks (PPT): in diastole if the reflux is systolic; in systole if the reflux is diastolic; in diastole and in systole if the reflux is diastolic-systolic. On this basis, it has been proposed CHIVA 2 distal outpatient treatment without CHIVA 1 with interesting haemodynamic effects. In the subcutaneous area by the pressure overload block it improves compartment drainage, reduces the peak of trans-mural pressure and the caliber of the varicose veins. In the intrafascial district: reduces peak and trans-mural walking pressure; does not change the drainage of the reflux; can restore an antegrade flow. KEY WORDS: Hemodyamic venous treatment, Vricose veins, Venous Hemodynamic Map (VHM).

Nel caso di eccessivo aumento pressorio del compartimento drenante profondo si ha l’inversione della direzione del flusso in quello superficiale. Per cui le vene varicose sarebbero l’effetto e non la causa di questo sovraccarico pressorio. L’inversione del gradiente pressorio in un compartimento provoca un circuito di reflusso (shunt venoso) solo se oltre al punto di fuga è attivo anche un punto di rientro. La chiusura del punto di fuga non risolve il momento eziologico del sovraccarico pressorio distrettuale. È quindi un trattamento sintomatico che non può ridurre il potenziale del sistema di causare recidive. Esistono tre tipi di reflusso: sistolico, diastolico e sistolico-diastolico. Su questa base è stato proposto il trattamento ambulatoriale emodinamico distale CHIVA 2 senza CHIVA 1 per trasformare i reflussi sistolici e sisto-diastolici in reflussi diastolici con l’obiettivo trasformare dei reflussi lunghi in brevi per prevenire le lesioni cutanee.
