Singular case of tardive anastomotic disjunction in a Dacron R vascular graft.

We investigated a case of anastomotic disjunction of the termino-lateral insertion of a bifurcate aortic graft in the right external iliac artery. The graft in woven Dacron R n. 19, was implanted in 1977 and the left femoral insertion became infected shortly after surgery.

Anastomotic disjunction in long-term patent vascular synthetic grafts in Dacron.

This study follows the recently published paper on the in vivo behaviour of patent Dacron vascular prostheses and focuses in particular on anastomotic disjunction. The question of the evolution of anastomoses was tackled by examining its three basic components: prosthetic tissue, suture thread and arterial wall. The authors' observations were based on material taken from reoperations performed between 7 and 18 years after the first graft.

[Biodegradation of dacron vascular prostheses. Physico-chemical, histological, morphometric and ultrastructural study].

The paper deals with study of long-term stability as far as concerns Dacron vascular prostheses in woven and knitted double velour. Among our vascular prostheses case-reports, we evaluated three of them explanted after 11, 12, 20 years; all of the prostheses were patent. Chemical-physical, histopathological and ultrastructural analysis have been carried on in order to evaluate in vivo ageing of the examined prostheses.

Are synthetic prostheses really inert? Preliminary results of a study on the biocompatibility of Dacron vascular prostheses and Silicone skin expanders.

This study investigates the histo-pathologic reactions induced by implant of prostheses in Dacron knitted double velour and skin expanders in Silicone elastomers. Particular attention was paid to the effect of these reactions on the tissue itself. In the case of vascular prostheses it was found that fibrous connective tissue tended to accumulate in and around the prosthesis.

[The correction of malformations of the internal carotid. A technical note].

A technical variation for the treatment of certain internal carotid malformations such as lengthening, bending and volvulus is reported. The variation consists in the creation of a "neobifurcation" that offers haemodynamic conditions very close to those of anatomical bifurcation.
