“…1% and 3% in the literature (19). After bifurcation replacement with Dacron grafts a per site incidence of 3.0 % in a total nu mber of 4 303 femoral anastomoses was reported by Szilagyi (31). In the study pr esent ed her e, there was no difference in the occurre nce of distal ana stomostic ane urysms between the groups during the first 42 postoperative months (one case in each group).…”

A total of 70 patients undergoing replacement of the aortic bifurcation between October 1983 and June 1985, were studied 5 years postoperatively for graft patency. In 35 cases a collagen-coated knitted Dacron prosthesis (group I) was implanted, while an identical, but uncoated, Dacron graft was used in a second group of 35 patients (group II). Distribution of vascular risk factors were similar in both patient groups. The underlying disease was aortoiliac occlusive disease in 24 patients of group I and in 33 of group II. Aortoiliac aneurysmal disease was present in 10 patients of group I and in 2 patients of group II. One patient of group I was suffering from Takayasu's disease of the descending type. At follow-up, all grafts were patent in group I, while in group II 8 distal limb occlusions occurred between 6 and 46 months postoperatively. This represents a 5-year limb patency rate of 100% for collagen-presealed grafts versus 88.6% for uncoated prostheses (p less than 0.01). A higher incidence of distal anastomotic aneurysms was found in group I (7/70 limbs) compared to group II (1/70 limbs) (p less than 0.05). It is concluded that long-term patency of knitted Dacron prostheses in aortic bifurcation replacement is not reduced by presealing with collagen. It appears that this type of coating may actually enhance long-term patency after reconstruction of the aortoiliac axis. The higher rate of distal anastomotic aneurysm formation in patients with presealed grafts, however, could not be correlated with a failure of the sealant material or with the underlying disease of the patients involved.

“…Our limb patency rates wer e 90 per cent at 5 years ; five patie nts complained of recurrent claudicatio n and two required sub sequ ent aortofemoral bypa ss . Nay lor et al (8) reported similar figures in 106 aort oiliac enda rte rectomies. Patency rates wer e 92 per cent at 5 years but dropped to 68 per cent at 10 years; fourt een patients received an aortofemoral bypass (at a mean time of 77 months) and only one pat ient required a major limb amputation.…”

“…Long-term complications relat ed to prosth esis are rare yet dr ead ed. Anastomotic an eurysm developed in 0.2 % of aortic and 1.2 % of iliac artery gra fting in Szilagyi et aI's experience (9). Graft or perigraft infections ranged from 0.77 to 2% at 5 years in many seri es (7, 8).…”

The ao rta shows an incidence of resteno sis on angiogra phic controls of 4 per cent at 10 years following endarte rectomy, wher eas this rate culminates to 41 per cent for operated extern al iliac arte ries (8). Recurrence or progression of the occlusive proc ess on this artery is the recognized main cause oflimb failur e 0 , 5).…”
