Morphological aspects of the aortofemoral graft thrombosis.

Sixty seven patients underwent aorto-femoral double velour grafting for aortoiliac occlusive disease and 38 patients were treated for recurrent lower limb ischemia following aortofemoral grafting. Apart from various clinical examinations the patients underwent angiography as well as the morphological investigation of specimens obtained from abdominal aortae, common femoral arteries and from grafts implanted into the aorto-femoral section. The examinations showed that diffuse intimal thickening may, in the course of atherosclerosis, convert itself into uncomplicated fibrous and further into complicated plaques impairing mainly graft outflow. The drawbacks of grafts are: 1) persistens of fibrin deposits on the luminal surface of the prosthesis which may contribute to thrombosis development, 2) appearance of foci or bands of hyalinized connective tissue causing the stiffening of the graft, 3) development of lesions resembling atheromatous changes at the anastomotic areas and, 4) anastomotic hyperplasia which may contribute to stenosis at the femoral implantation site.

Morphological changes in femoropopliteal venous grafts.

Morphological examination of specimens obtained from 82 venous grafts implanted into the femoropopliteal section were done. Intimal oedema, necrosis of single smooth muscle cells and partial exfoliation of the endothelium with as occurrence of parietal thrombi may lead to early graft impatency. The late cause of stenosed inner diameter below 4 mm in the venous graft was in 14,6% the hyperplasia of the smooth muscle cells and collagen and elastin fibres in the intima, whereas in 4,9% the changes were defined as graft atherosclerosis.

[Anaerobic bacteria in infections of lower limb ulcerations in patients with chronic atherosclerotic arterial occlusion].

In 76 patients with lower limb ulcerations in the course of atherosclerotic arterial occlusion, quantitative and quantitative bacteriological examinations, angiographic examinations and ultrasonographic measurements of pressures with simultaneous calculation of ankle/arm index were performed. At the same time the progression of ulceration healing was assessed after the operation. From the samples from four patients anaerobic bacteria were cultured: three times P. prevotii and twice P. acnes. It was found that these bacteria showed resistance to antibiotics used routinely in the treatment of diseases in which they may be the aetiological factor. The usefulness was demonstrated of quantitative examination of the bacterial flora in the ulcerations for the evaluation of their healing progression. Performing of antibiograms for anaerobic bacteria was found useful.

A case of malignant hyperthermia during epidural analgesia.

Malignant hyperthermia syndrome developed during epidural analgesia in 25-year-old female to be operated on for haemorrhoidal varices. After premedication with diazepam and atropine epidural analgesia was started with lidocaine 300 mg and bupivacaine 50 mg. Signs and symptoms of malignant hyperthermia syndrome appeared 30 min. later, with muscle rigidity, hyperpyrexia 41.5degrees C, and loss of consciousness. Treatment alleviating the syndrome was applied as indicated in this complication. Full recovery was obtained.
