Superficial epigastric vein sparing in the saphenous-femoral crossectomy or in the closures of the saphena magna

Ann Ital Chir. 2015:86:383-5.

Abstract

Aim: Considerations based on years of experience, have led our school to spare the superior collateral vein: the superficial epigastric vein.

Material of study: 1536 selective epigastric-sparing crossectomies performed with the support of Duplex US to detect the normal functioning of terminal saphenous-fermoral junction and femoral valves.

Results: The selective-haemodynamic sapheno-femoral junction ligation" (although this is not strictly done), saves from ligation (but only in the presence of functioning femoral and saphenous terminal valves) and division the termination of the superficial epigastric vein into the common femoral vein.

Discussion: Superficial epigastric vein is a descending draining vessel, assisted by gravity (unlike the inferior collaterals). In case of obesity or portal hypertension, the spared superficial epigastric vein could drain into the common femoral vein keeping its anatomical and haemodynamic functions.

Conclusions: The resulting anterograde flow will provide some flow through the residual saphenous stump, preventing its thrombosis.

Key words: Duplex US, Ligation, Saphenous vein.

Considerazioni basate su anni di esperienza, hanno portato la nostra scuola a preservare la vena collaterale superiore: la vena epigastrica superficiale. Questa rappresenta un vaso discendente che drena con l’ausilio della gravità (a differenza dei collaterali inferiori). In caso di obesità o ipertensione portale, la vena epigastrica superficiale risparmiata può defluire nella vena femorale comune mantenendo le sue funzioni anatomiche e emodinamiche. Questo concetto ci ha portato, ma solo in presenza delle valvole terminale femorale e safenica competenti, ad un “legatura selettiva emodinamica della giunzione safeno-femorale“ (anche se questo non viene fatto in modo rigido e sistematico), che evita la legatura dello sbocco della vena epigastrica superficiale nella vena femorale comune. Il flusso anterogrado risultante fornice un certo flusso attraverso il moncone di safena residuo, impedendone la trombosi.
