Claude Franceschi (born October 12, 1942) is an angiologist French MD. He is considered as a pioneer of Doppler ultrasound vascular investigation. His works are recognized worldwide, bringing a significant contribution to hemodynamics, pathophysiology, diagnosis and treatment of diseases of the arteries, veins and lymphatics. In the 1980s, he revolutionized the concept of venous disease with a new hemodynamic approach that led, instead of veins ablation, to conservative and hemodynamic ambulatory treatment of venous insufficiency (CHIVA). He further proposed a new theory regarding the hemorrhoid disease. For him, the main cause of this pathology is not due to the hemorrhoid veins but to a "fourth factor" i.e. the irritation of the anal canal. Consequently, he offered its treatment and prevention by a simple hygiene process. Finally, he discovered through Doppler ultrasound a disease of the lymphatic system related to the intermittent obstruction of the cervical thoracic duct ''The recurrent cervical swelling syndrome''. == Biography == Claude Franceschi studied at the Faculté de Medicine de Paris in 1960 and especially neuropsychiatry at the Salpêtrière (Paris) with Dr. Cyril Coupernik, and in Melun Psychiatric Hospital with Dr. Tosquelles. His interest in the cerebral circulation led him to work in the neurology laboratory of Dr. Jaquinot (Salpêtrière hospital) where he used one of the first Doppler ultrasonic machines (Delalande Electronique). 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). However, information provided by this noninvasive process remained poor and could not compete at that time with aggressive and dangerous methods such as angiography. Claude Franceschi then tried to decipher more deeply and in detail 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.

Vascular Doppler ultrasound investigation) in 1977.〔C.Franceschi ''L’Investigation vasculaire par ultrasonographie Doppler'', Masson Editeur Paris. 1977〕 In 1975, he worked at the Henry Dunant Hospital (Paris) with Prof. Jean Michel Cormier, pioneer of vascular surgery and then followed him at Saint Joseph Hospital (Paris). The latter decisively supported Claude Franceschi’s research and eventually would be the first to recognize and defend the diagnostic value of its results. This initial work specifically focused on the carotid arteries and then spread to all vessels. As the Scientific Advisor of ESAOTE Company, Claude Franceschi participated in technological and ergonomic advances of Doppler ultrasound machines. In addition, he produced invention patents to improve the diagnosis and care of patients. Since 1978, Claude Franceschi taught Doppler Ultrasound for the Angiology Degree (University Paris IV and Paris VII). He also taught in many other countries, including Algeria, Argentina, Chile, Italy, Spain, Tunisia and USA. He was invited in many international congresses and courses and published many books and articles in France and abroad. He is currently a consultant to the Fondation Hopital Saint Joseph Centre Marie Therese Paris (France) and Casa di Cura di San Camillo delle Figlie Cremona (Italy), and teaches the Diplome d’Angiologie and Doppler Vasculaire (University of CHU Pité-Salpétrière Paris). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Claude Franceschi」の詳細全文を読む スポンサード リンク
