Claude Franceschi

After Shigeo Satomura who detected for the first time the blood flow with a Doppler Ultrasound machine,Study of blood flowing vessels by ultrasonics 1959 Gene Strandness measured the blood pressure at the ankle (1967), Léandre Pourcelot proposed the Arterial resistivity index (1974), and Gosling the Pulsatility index (1974).

Claude Franceschi then tried to analyze more exactly the hemodynamic meaning of the Doppler signal wave from normal and diseased vessels. He published the results at numerous conferences Among which: Réunion de chirurgie vasculaire Hôpital Saint Joseph Vélocimétrie par Ecographie Doppler, Apr. 29–30 April 1976 Marseille, France; Fourth Réunion de chirurgie vasculaire Saint Joseph Hospital, Oct. 29-30 1979 Marseille, France; Corso di alta formazione Dalla diagnosi clinica al trattamento delle malattie vascolari Oct. 5 2006, Bari Italy; Primeras jornadas internacionales de eci-doppler vascular.

CHIVA: principles and clinical outcomes, Dadon Aug. 10-14 2014, Sydney, Australia and in the French book "L'Investigation vasculaire par ultrasonographie Doppler" ("Vascular Doppler ultrasound investigation") in 1977.C.Franceschi, L'Investigation vasculaire par ultrasonographie Doppler, Masson Editeur Paris. 1977

Franceschi's major work was to match the principles of fluid mechanics[http://www.pagepressjournals.org/index.php/vl/article/view/Hemodynamics.2013.1/1181 Definition of the venous hemodynamics parameters and concepts] with arterial and venous hemodynamics. After studying the correlations between the Doppler ultrasound, radiological and surgical data, he laid down the methodological and semiotic bases of vascular Doppler ultrasound.

• In 1977, he published the very first book in the world on Vascular Doppler Exploration (Vascular investigation by Doppler ultrasound) C.Franceschi. L'Investigation vasculaire par ultrasonographie Doppler, Masson Editeur Paris 1977 then translated into Italian and Spanish, in which he describes the hemodynamic principles and their expression in terms of Doppler signal.{{Cite web|url=https://copy.com/Pfx1OChnfsgK|title = Cahoots — Ann Arbor tech coworking}} This data remains the undisputed reference for the stenosis quantification and a quality diagnostic.F.Luizy. Le Doppler continu, historique. EDV Echodoppler Vasculaire Avril 2009 N°1 In particular, he worked on the criteria of arterial stenosis of limbs and carotids, Carotid pre-thrombosis, the Pressure-Perfusion Index (Franceschi Index),C. Franceschi (indice de) Les Noms en Médecine Vasculaire. Les noms en médecine vasculaire - Congrès relation Beaufour Ipsen, 2002 https://copy.com/iA1CtMZDS6tn the Carotid Ratio and the exploration of the Circle of Willis.
• In 1978, he published the first observations of carotid plaque regression.
• In 1980 he described the Fistula Flow Ratio (French 'RDF') to assess the flow of arteriovenous fistulas, especially in renal dialysis.{{cite journal | last1 = Franceschi | first1 = C.

• In 1981, he invented an interface process (INPI registration N° 81 22294) https://copy.com/keb1YUZa6MGa which allows for the first time the visualization of supra-aortic arteries by B-Mode echography.Première médicale " Une artériographie non sanglante des troncs supra-aortiques " MCV 1981 https://copy.com/taYNmiwJFK6d A Doppler method for exploring the compensatory ways of the cerebro-cervical vasculature was published the same year.
• In 1986, he published the first book of vascular ultrasound imaging Précis d'échotomographie vasculaire C. FRANCESCHI, G.FRANCO, F.LUIZY, M.TANITTE. PRÉCIS D'ECHOTOMOGRAPHIE VASCULAIRE. Vigot, Paris, 1986 translated into Italian: « Compendio di ecotomografia vascolare »
• In 1988, he published the book La cure Conservatrice et Hémodynamique de l'Insuffisance Veineuse en Ambulatoire: CHIVA C.Franceschi. La cure Conservatrice et Hémodynamique de l'Insuffisance Veineuse en Ambulatoire CHIVA Editions de L'Armançon. Precy sous Thil France also translated into English and Italian, where he offers a new approach to the physiology of deep and superficial venous circulation, introducing new concepts such as « Dynamic hydrostatic pressure fractioning », the veno-venous shunts and vicarious evolution of varices.C.FRANCESCHI. Dynamic fractionizing of hydrostatic pressure, close and open shunt, vicarious varicose evolution: how have these concepts made the treatment of varices evolve? Éditions phlébologiques françaises, vol 56, n°1/2003. P.6C.FRANCESCHI Insuffisance veineuse et fractionnement dynamique de la colonne de pression hydrostatique. Venous insufficiency and dynamic fractionating of the hydrostatic pressure column STV. Sang thrombose vaisseaux 2001, 13, 307 – 310 STV. Sang thrombose vaisseaux A. 2001, vol. 13, n° 5, pp. 307-310

According to this theory, varicose veins are not, as well as edema and ulcers, the cause of the venous insufficiency, but the result of venous valves incompetence instead and/or obstacles to the flow.

Furthermore, destroying varices in impeding the natural drainage of the skin, would be responsible for relapses by a compensation effect (vicarious shunts).

The CHIVA method removes the overload flow and pressure, resulting in ulcer healing and returning the normal caliber of the veins, including varicose veins. It merely consists in the accurate splitting of the gravitational hydrostatic pressure of the venous column and in the disconnection of closed shunts (depending on the particular configuration of each patient). From 1 to 5 divisions/ligatures are performed under local anesthetics and without hospitalization (ambulatory).

In addition, the saphenous veins are saved, a considerable advantage since these veins are the best material for by-passing the peripheral arteries, and completing Coronary artery bypass surgery, more and more necessary for the aging population.Link [http://fr.slideshare.net/pmphone/evaluation-du-capital-veineux Capital veineux et patient arthéromateux]

Several randomized controlled trials and a Cochrane Library review have demonstrated CHIVA superiority in certain specific anatomical situations to conventional removal (stripping) of the saphenous vein.{{cite journal | last1 = Carandina | first1 = S | last2 = Mari | first2 = C | last3 = De Palma | first3 = M | last4 = Marcellino | first4 = MG | last5 = Cisno | first5 = C | last6 = Legnaro | first6 = A | display-authors = etal | year = 2008 | title = Varicose Vein Stripping vs Haemodynamic Correction (CHIVA): a long term randomised trial | journal = European Journal of Vascular and Endovascular Surgery | volume = 35 | issue = 2| pages = 230–7 | doi=10.1016/j.ejvs.2007.09.011| pmid = 17964822 | doi-access = free }}Parés JO, Juan J, Tellez R, Mata A, Moreno C, Quer FX, et l.
