Arterial Reconstruction in Cutaneous Ischaemic Lesions

Iliofemoral venous thrombosis. Pathological considerations and surgical management

“…Embolism may be massive and fatal and may occur before leg signs are present, part of the 'silent' leg syndrome (Mavor and Galloway, 1967a). Iliofemoral venous thrombosis is often a slow insidious process, and a stage of partial or incomplete occlusion of the vein may be present for weeks or months, detectable only by femoral venography (Mavor and Galloway, 1967a). Clot-formation in fact may be extensive without occlusion (Sevitt, 1962) (Figs.…”

“…It would appear therefore that peripheral venous thrombosis is not in itself of serious clinical import. Because of the collateral venous arrangements, acute venous insufficiency does not occur and late morbidity is related entirely to perforator damage (Mavor and Galloway, 1967b). Pulmonary embolism with its origin in this segment is not usually significant, cannot be massive, and can only become serious because of the cumulative effect of many small * Twenty-four cases were bilateral.…”

“…The common iliac vein is usually initially involved, the left more so than the right in a ratio of 3 : I (Table II). collateral ' run-around ' veins for such an obstruction are always adequate, and all legs have two by-passes, and 80 per cent have three by-passes for this segment (Mavor and Galloway, 1967b). Venous inflow at the common femoral area via the long saphenous vein, the profunda femoris, and venae comitantes is always considerable, and likely to diminish the chances of propagation from peripheral to proximal segment.…”

“…When the right side is affected, embolism is more likely to occur, the more indirect transverse lie of the left common iliac vein presumably affording some protection (Table IZ). Embolism may be massive and fatal and may occur before leg signs are present, part of the 'silent' leg syndrome (Mavor and Galloway, 1967a). Iliofemoral venous thrombosis is often a slow insidious process, and a stage of partial or incomplete occlusion of the vein may be present for weeks or months, detectable only by femoral venography (Mavor and Galloway, 1967a).…”

“…The termination of the profunda femoris vein can be taken as the anatomical division between the two types (Mavor and Galloway, 1967b).…”
