[Lumbar sympathectomy for arteritis. A reliable and (almost) seventy year-old technique].

The old procedure of lumbar sympathectomy has long been the only chance of avoiding amputation for arteritic patients. Its field of application has shifted as reconstructive surgery and medical therapy made progress, and it is no longer the only solution and has more precise indications. Proper evaluation of its chances of success according to the individual situations allows establishing its potential and limitations. This simple procedure, entailing no risk for the future, deserves remaining among the available means for the treatment of arteritis, despite its age.

[Spontaneous dissection of the internal carotid artery].

Spontaneous dissections of internal carotid artery are known from more than 30 years and their incidence is now specified, several hundred cases being published. The case reported here illustrates very well the setting problems of this disease and explains why the incidence of the mild forms has been underestimated. The case of a sixty years old man with vague vertiginous feeling, headache and moderate ocular troubles is presented. The clinical signs disappeared within six weeks. The patient was seen again in good health seven years later. The medical practitioner by asking a systematic Doppler examination led to the diagnosis confirmed by arteriography. A complete recanalization of the internal carotid artery occurred. These forms with spontaneous favourable prognosis represent at least 50% of the cases.

[Interosseous dorsal artery of the first intermetatarsal space: anatomic variations and value in functional vascular studies].

The first dorsal metatarsal artery (MDA) is usually described as the last collateral branch of dorsalis pedis artery (DPA, which anastomoses with the lateral plantar branch of the posterior tibial artery (PTA). Doppler assessment on DMA of a flow does not always mean that DPA is free, but may show a functional plantar arch. The aim of this study was to determinate the patency rate of this plantar arch and to appreciate the part of DPA in the vascularisation of the foot. Anatomical descriptions were compared with our own dissections, (25 cadavers and 55 arteriographies in fetus), angiographic analysis and vascular plastic casts. The functional aspect of this study was made by Doppler examination of DMA using alternative or simultaneous compression of the main arteries of the ankle, until doppler curves were canceled. That was done on healthy volunteers and arteriosclerotic patients. The results show that, from the anatomical viewpoint, the plantar arch is almost always present, since it was found in 88% of adult pieces. Nevertheless, on Doppler examination, the plantar arch was found functional only in 64% of healthy people. The difference between the two rates emphasizes the fact that anatomical anastomosis are note always open, according to the subject and probably to the age. Looking after MDA permeability in patients with arteriosclerosis leads to point out the main vascular access to the foot, for limb salvage, and the leading part of distal anastomosis to keep good trophicity of the toes.

[Anatomical organization, organogenesis and innervation of the arteries of the hand].

The authors sum up the anatomical aspects of the arteries of the hand. They emphasise the fact that, by the side of the classical description; there is a lot of variations. These can be explained by organogenesis, showing that hand arteries pass over several stages, before reaching the terminal one. Generally, it seems that the classical diagram correspond to the majority of cases, and that there is a main flow for hand's arteries: this are the superficial and deep arches, which give common and proper digital arteries. About the innervation, this structures are very richly innervated, but this sympathetic innervation is not so precisely delimited in its topography, and for that reason, its seems to be difficult to give an clear diagram of its origin and distribution. That can explain surgical treatment's failure in vasomotor syndromes of upper limbs.

[Hypoplasia of the abdominal aorta. Review of the literature apropos of 4 cases].

The authors report 4 cases of abdominal aortic hypoplasia and, reviewing the literature, recall the anatomical classifications and the clinical aspects predominated by arterial hypertension and arterial claudication. Pathogenesis does not seem to be univocal and some arguments are in favor of a congenital origin when others plead for an acquired inflammatory disease. But above forty one must consider the possible responsibility of added atheroma. The numerous operative techniques point out the difficulties encountered in the treatment of the aortic lesions and associated arterial, mainly renal lesions. The polymorphism and complexity of these lesions oblige to vary the choice of indications.

[Cockett's syndrome. Treatment by venous envelopment in a ringed prosthesis].

The surgical treatment of Cockett's synechiae is now well established, with only minor variations. Various techniques have been suggested to solve the problem of arterial compression, but none of these is fully satisfactory. The authors favour the use of new externally supported grafts, notably the ringed polytetrafluoroethylene (PTFE) prosthesis, to protect the left iliac vein, these grafts being effective and easy to apply.

[Postoperative urinary infections].

Urinary tract infection was shown to be both common and serious in the postoperative period. Among 87 patients who underwent urinary catheterization immediately before or after surgery, 28 (32%) had urinary tract infection. Urinary tract catheterization is necessary in some instances but rapid removal and routine culture of catheters is requisite.

[Vasa-vasorum (author's transl)].

More than a common descriptive interest, this researches about vasa-vasorum have been carried on to give some anatomical basis, to the part acted by those vessels in arterial wall life. Microdissections, X-rays diaphanisation enable us to systematize even in human kind than in animal species, the main aspects of this vascularisation. The conception of a double irrigation, from the lumen and from the vasa of the blood vessels, and the presence of a venous and lymphatic drainage, can give us the basis of an interpretation of the beginning of the main arterial diseases.

[Arterial collateral ways of the limb arteries (author's transl)].

Arterial collateral ways are reviewed correlatively with five differents levels of obliteration : aortic, iliac, ilio-femoral, femoro-popliteal, dista. A double visceral and parietal supply system caracterize each obliterated level; the importance of this double system varies considerably with the site of obliteration.
