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. The infection was treated according to standard procedures with removal of the infected branch, reconstruction with the transobturatory by-pass and antibiotics. For antibiotic treatment of local and general sepsis the approach was completely new as regards dose regimen and duration. In 1993 a pseudoaneurysm developed through weakening of the right iliac anastomosis. In view of the anamnesis we were surprised to find that the origin was of a mechanical nature.

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. These data enable the authors to affirm that the prosthesis undergoes a general physical and chemical deterioration which varies in intensity according to the type of weaving. On the contrary, in the anastomotic zone this phenomenon is not intense enough to jeopardize the anchorage of the suture thread since the original weft does not show any loss of compactness. In spite of surface morphological deterioration of various intensity, the suture threads maintain satisfactory mechanical properties and structural integrity. The artery wall in the anastomotic zone shows a massive degeneration in terms of its true anatomic structure responsible for the rupture of the suture rima. On the basis of these results the authors conclude that this phenomenon represents the "Achilles' heel" of anastomotic junction.

[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. The results all indicate strong alterations of the original properties related to double velour of knitted prostheses and weak alterations of woven one.

[Prosthesis of knitted dacron velour: an unusual case of late complications].

A case of aneurysmal dilatation of the right branch of a knitted dacron velour prosthesis and then of pseudoaneurysm from its termino-lateral aortic insertion 9 and 10 years after implantation is reported. Histological examination carried out on the prosthesis caused great perplexity in both cases as there were evident signs of fibre fragmentation by polynucleate elements.

[Are synthetic prostheses really inert?].

Five cases of long-term complications of a homogeneous series of 78 aorto-iliac-femoral by-passes in knitted Dacron velour observed between 1976 and 1988 are reported. The cases were aneurysm of a prosthetic branch and pseudoaneurysms of aortic and femoral anastomoses. The paper concerns not so much the presentation of the causes, recognised by most Authors, that might have determined the ongoing pathology as the observation of a histologic situation not previously described: namely the presence of macrophages which attack Dacron fibres and fragment them.

[Vascular abnormalities of the limbs. Some observations on the classification].

In the light of the most recent non-invasive and invasive diagnostic findings, E. Malan's classification of 1974 is reproposed. This introduces the concept of prevalence to Malan-Puglianisi's previous classification of 1964. A common denominator is proposed for all vascular malformations, not only those involving the extremities, to simplify this pathology still further: the presence or otherwise of the diversion phenomenon.

[Stripping of the internal and external saphenous veins in a day hospital].

The procedure used to carry out internal and external saphenectomy operations in a day-hospital is described. The choice of cases is conditioned by phlebographic examination, and by talks between patients, anaesthetist and surgeon. Anaesthesia is local and general at the time of stripping. The technique is the classical one of saphenectomy according to the school of Edmondo Malan, with some variations.

[Changes in the plasma magnesium content in patients subjected to cardiopulmonary bypass].

Changes in plasma magnesium content in 17 patients operated in extracorporeal circulation are reported. Values were low at the end of the operation, but rose at the end of the first day to achieve spontaneous resolution of the condition within 3 days. No close relationship between such loss and immediate postoperative arrhythmia could be discerned. Attention is, however, drawn to 3 cases in which ventricular fibrillation was not resolved until electric shock treatment was preceded by the administration of magnesium sulphate.
