McDermott M W - - 1989
A modification of the technique combining sagittal strip, circular occipital and biparietal wedge craniectomies (Albright's procedure) for the treatment of sagittal synostosis, with prominent occipital bossing, is described. "Keyhole," as opposed to wedge, parietal craniectomies allow improvement in the shape of the skull, beginning intraoperatively, while eliminating the outbending of ...
Psaila J V - - 1989
Veins taken from patients undergoing surgery for varicose veins were compared with those obtained from patients undergoing other surgical procedures ('normals'). Varicose veins had a lower breaking strength and breaking energy than normal veins. Elastic stiffness was less in normals (tan theta = 41 (24] than in varicose veins (tan ...

The phlebographic findings in nine patients with primary varicose veins on the lateral aspect of the thigh are described. These were shown by varicography to connect primarily with the deep femoral vein via communicating veins: the symptoms were either cosmetic or mild aching in the thigh. Surgical treatment, if indicated, ...
Savolainen H - - 1988
Recurrent varicose veins are a common problem. Ascending phlebography has been used to identify possible incompetent perforating veins. The method is accurate in the leg, but much less so in the thigh. In this study, thirteen patients with recurrent varicose veins were examined with varicography, i.e. direct injection of contrast ...
Lary B G - - 1987
Surgical stripping of the varicose saphenous venous systems combined with avulsion and extraction of collateral branches through very small incisions has yielded excellent cosmetic and functional results in 1,500 operative procedures. Sclerotherapy of varicose veins is an established procedure. Injection with the patient in the upright position followed by mild ...
Haimovici H - - 1987
The conventional pathogenesis of varicose veins and their subsequent development is essentially based on primary valvular insufficiency of the main saphenous trunk and incompetence of the perforating veins. In contrast, the concept of the pathogenesis of varicose veins presented in this review is based on the presence of arteriovenous (AV) ...
Segerberg-Konttinen M - - 1987
The study presents a method for the demonstration of esophageal varices at autopsy by gastroesophageal phlebography. The veins visible on the radiographs were controlled and evaluated by studying the gross appearance of sections of the esophagus at the level of the varicose veins and by histologic examination of the sections. ...
Keeling F P - - 1987
Forty-nine legs in 41 patients with primary varicose veins were investigated by varicography, (direct injection of varicose veins with contrast medium). Additional features not found at clinical examination, such as reduplication of the long saphenous vein, unusual terminations of the short saphenous vein and incompetent perforating veins, were found in ...
Rowan R A - - 1987
The purpose of this study was to provide anatomical information about innervation density and the neuromuscular relationship in the rabbit central ear artery and its main side branch, so that, when combined with functional observations, a better understanding of neuroeffector mechanisms in these vessels could be established. Electron-microscopic methods were ...

The defendant, an obstetrician and gynaecologist, was accused of voluntarily causing a woman to miscarry, such miscarriage having been performed without good faith and an intention to save the woman's life. The Court upheld the conviction of the defendant, rejecting his argument, supported by an expert witness, that he had ...
Thomas M L - - 1986
Forty lower extremities in 29 patients with recurrent varicose veins have been investigated by varicography. In 29 lower extremities the recurrent varicosities were on the long saphenous venous system and in 11 lower extremities on the short saphenous system. The recurrences consisted of varicose segments or tributaries of the long ...
Morris J L - - 1986
The innervation of the major arteries and heart of the toad (Bufo marinus) was examined by use of glyoxylic acid-induced catecholamine fluorescence and peptide immunohistochemistry. All arteries possessed a moderate to dense plexus of adrenergic axons, which also showed neuropeptide Y-like immunoreactivity (NPY-LI). Some adrenergic axons in the intracardiac vagal ...
Ameli F M - - 1986
Varicose veins are a very common problem, affecting women more than men. The major concern is usually the unsightly appearance of the veins. Various options to deal with this problem are discussed-- compression stockings, compression sclerotherapy and surgery. For good results and patient satisfaction, the cause and natural history of ...
Macfarlane R - - 1985
In 35 legs being operated on for varicose veins a venogram showed that the part of the long saphenous vein below the knee does not undergo varicose dilatation. In 7 of the 9 examined postoperatively this segment remained patent after the vein above was stripped. Varicose veins resulting from saphenofemoral ...
Haimovici H - - 1985
The use of the Doppler ultrasound detector is described for the diagnosis of arteriovenous (AV) shunting in varicose veins. This investigation was carried out in 34 patients, 27 women and seven men. A total of 68 limbs with varicose veins and 48 control limbs with either no varicose veins or ...
Large J - - 1985
It is believed that many surgeons, by adopting 'stripping' as the routine surgical treatment of significant varicose veins may be sacrificing many major leg veins which could be potentially valuable arterial grafts. A protocol of surgery is suggested which replaces stripping by the stab-avulsion technique. Thus all varices are removed ...
Scurr J H - - 1985
There is uncertainty regarding the most satisfactory technique of lower limb compression following sclerotherapy for varicose veins. We have compared a standard bandaging technique with a high pressure compression stocking in a randomised trial. Efficacy was judged on the success of injections, complications of the treatment and patient satisfaction. In ...
Cowen T - - 1984
The neuromuscular relationships of the guinea-pig renal artery, which has previously been shown to be noradrenergically innervated but 'non-functional', i.e. not responsive to nerve stimulation in vitro, is compared with those of two arteries where functional neuromuscular transmission occurs: the carotid artery, where responses to nerve stimulation are slow and ...
Starnes H F - - 1984
Superficial venography was used in nine lower limbs of eight patients with recurrent varicose veins occurring after high ligation or stripping. This technique demonstrated four different types of recurrence and identified the cause in individual patients. The most common type of recurrence was not a missed tributary of the long ...
Conell L J - - 1983
A withdrawal syndrome occurred in two patients after substitution of a short-acting benzodiazepine for a long-acting benzodiazepine. Both patients had used long-acting benzodiazepines on a daily basis for many years. In one case, oxazepam was substituted for diazepam, and in the other, temazepam was substituted for flurazepam hydrochloride. In both ...

A microporous, compliant and biodegradable vascular prosthesis prepared from a polyurethane-poly-L-lactic-acid (PU-PLLA) mixture, induces fast growth of a neo-artery after implantation as an arterial substitute. The prostheses used in this study resulted in 100% patency. Mechanical functionality of the neo-arteries is suggested by the regeneration of elastic laminae throughout the ...
Agrifoglio G - - 1983
The role of incompetent perforating veins in chronic venous disease is well established. The determination of hemodynamic alterations and perforating veins location is evaluated by physical examination, phlebography and ultrasonography. All patients with perforating veins failure underwent surgical treatment. From 1971 to 1982, 6000 patients with lower limbs primary varicose ...
Husni E A - - 1982
In the absence of malignancy, thrombophlebitis of the lower limb is invariably associated with pre-existent varicose veins. Not until pulmonary embolism was reported to occur in superficial phlebitis did the clinician introduce anticoagulants and/or surgery in the management of this condition. In an effort to reach an effective approach to ...
Yu Y L - - 1982
Thirty-one patients with ectasia of intracranial arteries were studied. The carotid system was more frequently involved than the vertebrobasilar. The condition is relatively rare and usually occurs with other vascular disease. Ectasia presents with a variety of neurological symptoms, amongst which visual disorders are common. The overall mortality was 52%, ...
Samuels P B - - 1981
A technique for varicose vein surgery is described which allows maximum removal of varicose veins and the trunks draining into them. Hemostasis by means of tantalum clips allows for distal ligation of branches beyond their bifurcations in sites of difficult access. This results in minimal blood loss and enables subdivision ...
Schalin L - - 1981
By thermography the hottest spots of varicosities were localized. At surgery they were found to correlate well to the sites of small pulsating arteries joining the varicosities but did not show correspondence to incompetent perforating veins. At peroperative measurements these arteriovenous communications (AVC) ranged from 0.1-2 mm. Most of them ...
Weissberg D - - 1980
Treatment by compression sclerotherapy was carried out in 80 legs with symptomatic varicose veins. Excellent results were achieved initially in 60 legs, and there was improvement after retreatment of an additional six, for a total of 66 legs. In the remaining 14 legs, there was partial, but considerable, improvement. There ...
Lewis M R - - 1980
Phlebography is a useful examination if a standardized technic is carefully used, and it can be relied upon to diagnose acute thrombophlebitis definitively or to rule it out. The 200 consecutive phlebograms reviewed produced no mortality or pulmonary embolism, and only minimal morbidity. Phlebograms are also useful in mapping before ...
Leu H J - - 1979
Venous valves do not play a role in pathogenesis of primary varicose veins. Their number remains constant during life time. In varicose veins their insufficiency is secondary. Intimal fibrosis is no prerequisite for the development of varicose veins. It is a frequent finding in non-varicose veins of all age groups. ...
Kramlinger K G - - 1979
A simple, inexpensive, reproducible method is described for prominently displaying the islets of Langerhans. The method consists of sequential arterial perfusion of the organ of the sacrificed animal with saline, formalin, hematoxylin, and water, followed by clearing in methyl salicylate. The procedure should be useful whenever islet tissue needs to ...
Thomson H - - 1979
The superficial venous system was dissected in 60 legs. A possible function is ascribed to the long saphenous vein and an argument against its stripping in varicose veins presented. Abnormality of the long saphenous vein and its association with varicose veins is described. Particular features of the saphenous tributaries are ...
Klinge E - - 1978
The penile artery of the bull contained significant amounts of acetylcholine, noradrenaline and dopamine, and its axon profiles contained either numerous small granular or agranular vesicles, as well as some large granular vesicles. In the dorsal metatarsal artery, only noradrenaline and dopamine were detectable, and the axon profiles observed contained ...
Fanter D L - - 1978
A method is described for producing silicone rubber molds and casting epoxy tensile coupons in these molds. The resulting epoxy coupons have smooth, glossy surfaces and are dimensionally reproducible. The process uses no release agents, coolants, or other possible contaminants and yields high-quality epoxy coupons.
Marechal R E - - 1977
Bilateral ligature of the superficial temporal arteries and of the posterior auricular arteries is proposed as a treatment for seborrheic alopecia. The arterial circulatory dynamics are, thus, replaced by capillary circulatory dynamics. Hypoxia is produced which inhibits enzymatic systems and lessens nocuous action of androgen and lipid factors on the ...
Van Bellen B - - 1977
In order to investigate the possibility of lymphatic disruption occurring during varicose vein surgery, lymphangiography performed by a modification of the Kinmonth technique was done in seven patients before and after standard surgical ablation of primary varicose veins. All seven patients demonstrated marked disruption of lymphatics. Extravasation of lymphangiogram contrast ...
Myers H L - - 1976
The varicose tendency cannot be cured but it can be controlled. Injection compression sclerotherapy, if performed competently on selected patients, is an effective treatment. It is a relatively simple, economical, safe, and ambulatory form of therapy which has a major place in the management of varicose veins. The technique for ...
Weintraub A M - - 1976
Varicosities may be due to congenital weakness of the vein walls or valves, or may be secondary to deep thrombophlebitis. The latter leads to loss of valve competency in the communicating veins and transmission of relatively high pressures to the superficial system. Edema, thrombophlebitis and stasis dermatitis are common side ...
Fentem P H - - 1976
A method has been devised to allow reliable comparison of different strengths and constructions of support hosiery. Five garments were evaluated for the compression they exerted on the leg and their ability to limit the distension of a model varicose vein. Stockings and tights which provide modest compression can achieve ...
Martinet J D - - 1976
The following technique is normally used in our Phlebology Centre for varicose veins with ostial incapacity of the internal saphenous vein: A first stage, consisting of an enlarged crossectomy of the internal saphenous vein, combined with a stripping operation, more often long than short. In a second stage it is ...

For anal incontinence caused by destroyed or absent sphincter mechanism, a levator sling serving as a substitute puborectalis sling was used in five patients with incontinence of varied causes with good to excellent results. This sling was constructed bu freeing the insertion of the pubococcygeus and the ileococcygeus muscles from ...
Barnes R W - - 1975
The Doppler ultrasonic velocity detector and the strain gauge plethysmograph were used to differentiate qualitatively and quantitatively primary from secondary varicose veins. Studies were performed in 21 limbs of 14 normal persons, nine limbs of eight patients with varices secondary to deep venous disease. The latter group of patients was ...
Conrad P - - 1975
A "new" procedure for dealing with varicose veins associated with severe-to-moderate long saphenous vein incompetence is described. It consists of a combination of high ligation of the saphenofemoral junction and stripping of the long saphenous vein, with compression sclerotherapy of its tributaries and veins which are varicose because of incompetent ...
Sheckman P - - 1974
The interesting problem is considered of a comatose alcoholic diabetic with an extremely high systolic blood pressure, as determined by the usual means, who was subsequently found to have severe medial calcinosis and normal intraarterial blood pressure. The syndrome of the noncompressible brachial artery surely accounts for this patient's falsely ...
Burkitt D P - - 1972
Current concepts on the aetiology of varicose veins, deep vein thrombosis, and haemorrhoids have been examined and, in the light of epidemiological evidence, found wanting.It is suggested that the fundamental cause of these disorders is faecal arrest which is the result of a low-residue diet.
Hutchinson N A - - 1970
A case of persistent proatlantal artery is described and the developmental anatomy reviewed. This vessel, arising from the internal carotid artery in the neck, is liable to be confused with the hypoglossal artery, but unlike the latter it forms the vertebral artery outside the skull and enters through the foramen ...

Fresh frozen skeletal muscles of rats, rabbits, and humans were sectioned in a cryostat. Sections 12 to 32 micra thick were incubated in a substrate solution for the histochemical demonstration of non-specific alkaline phosphatase activity. A modified azo dye coupling technique was used at pH 9.5. Localized areas of high ...
ELLENBURG R - - 1958
Adequate treatment of varicose veins requires thorough mapping of perforating veins, communicating veins and "blow out" areas. Combined ligations, stripping and injection of sclerotic substances after operation is the most effective regimen of therapy. The technique of stripping is facilitated by isolating the saphenous vein at the ankle, inserting the ...
