Abstract

The authors present clinical and instrumental results of N. 543 operations executed by CHIVA system. These cases are the result of trial performed in seven SIOC (Italian Society of CHIVA Operators) centers executed from November ’87 to July ’89. Functional and aesthetic results had been very good on over 85% of all cases; superficial thrombosis were verified on 10% of all cases but almost completely asymptomatic. The aa. propose to start a deeper trial on 500 patients choose by rigorous criteria of inclusion.

Abstract

From January 1987 to December 1988, 100 conservative and hemodynamic treatments of superficial venous insufficiency in great saphenous vein territory, have been done on 86 patients. They were 32 men, whose mean age was 53.7 years, and 54 women, whose mean age was 44.5 years. Indication for surgery was mainly functional in 28 cases, esthetic in 26 cases, both in 25 cases and trophic problems in 21 cases. Ligation of the sapheno-femoral junction has been done in 91 cases (62 clips, 9 clips and ligations, 11 ligations, 9 sutures). Distal interruption has been done above knee in 24 cases, below knee in 50 cases, and both in 16 cases. Early postoperative complications have been one septic collection of the groin, one hematoma of the groin, one durable contusion of the saphenous nerve, and 21 superficial venous thrombosis. There were six thrombosis of excluded branches, seven subtotal thrombosis of the saphenous and height partial thrombosis of the saphenous vein. Subtotal thrombosis of the saphenous vein were due either to a mistake in position of distal ligation in three cases, either to a too large saphenous vein in four cases. Five out of height partial thrombosis occurred on saphenous veins larger than ten millimeters. Follow up was obtained, in 1990, so that all patients had at least one year of follow-up. Seven patients have been lost for follow-up. Three patients had recurrence because of failure of the clip. An additional procedure was necessary in 30 patients. Functional results were correct in 89% of patients, and esthetical results in 68% of patients.

Abstract

Presentation of the characteristics of this technique described by the French physician C. Franceschi, in 1988. Our Department began to apply this method on may 1991 and we are the first team in Spain to carry out and systematize this cure. Up to date, 85 patients have been treated with a residual vein percentage of 18%. Morbidity is low and slight. There is no mortality. This method is considered interesting as it does not require hospitalization, conserves the vein capital of the patient, and has low labour and health care costs.

Abstract

BACKGROUND:

Hemodynamic correction (CHIVA) is a conservative, ambulatory, and controversial varicose vein treatment. It consists of selected ligatures of the superficial venous system decided by means of preoperative duplex mapping.

OBJECTIVE:

Prospective evaluation of 80 patients, operated on according to the CHIVA technique described by Claude Franceschi. Mean follow-up length was 30 months.

METHODS:

Fifty-five consecutive patients were operated on after clinical, ultrasonographic, ambulatory venous pressure and light reflection rheography evaluations. After a 3-year follow-up, another 25 consecutive patients were selected applying some exclusion criteria that emerged in the first part of the study. This second series was operated on by means of intraoperative angioscopy. The same preoperative evaluations have been used to study the outcome in all patients.
