[Varicocele. Ligation of the internal spermatic vein using laparoscopic approach]. / Varicocele. Legatura della vena spermatica interna per via laparoscopica.

It is now unquestionable that varicocele represents one of the main causes of male infertility, and thus requires appropriate surgical treatment. Inguinal and retroperitoneal methods have for some time been the most widely used. However, a significant postoperative morbidity and relatively long convalescence have prompted the search for alternative surgical techniques, such as percutaneous sclero-embolisation and microsurgery. Laparoscopic treatment of varicocele is a relatively recent surgical technique. The first studies by Sanchez de Badajoz date back to 1988 and to date a relatively small number of cases have been reported. The authors analyse the results in 54 patients treated over a period of two and a half years; 13 cases also presented inguinal hernia pathology which was treated during the same operation by applying a polypropylene graft again using a laparoscopic approach; the latter method has been routinely applied since 1992 in over 1000 cases with excellent results. The internal spermatic artery was always identified and preserved. No peri- or postoperative complications were observed. A follow-up was performed at 10 months after surgery and showed results which although referred to a relatively small series, were certainly better than those reported in the literature using traditional surgical techniques; in addition, this method also reveals interesting possibilities for the treatment of associated pathologies during the same operation, with obvious advantages in terms of costs and patient compliance.

[Pre- and postoperative color Doppler ultrasonography of myocutaneous flaps in reconstructive surgery of the breast]. / L'eco color-Doppler nello studio pre e postoperatorio dei lembi miocutanei in chirurgia ricostruttiva della mammella.

The authors present their experience in the study of blood supply of flaps. The machine used to study both pre and postoperatively the myocutaneous flap is the echo-color Doppler, a brand new device which has recently been used in investigating the morphology and the blood supply. The use of such method has provided us with the following information: detailed ultrasound structure of the skin, subcutaneous and muscular tissues of the examined flap; localization of vessels within the flap; size of the vessel in its whole length; quality and speed of both the arterial and venous flow. Such information is very important for the surgeon to plan in detail the reconstruction by knowing the blood supply of myocutaneous flap.

Anatomo-clinical study of rectus abdominis myocutaneous flap.

At the Plastic and Reconstructive Surgery Department of Perugia, 52 patients were examined by color flow duplex scanning, in order to study rectus abdominis myocutaneous flap vascular supply before surgical procedures. This ultrasound technique permits a precise and accurate measurement of blood flow volume and velocity within the epigastric arteries (which represent the superior and inferior vascular pedicles of the flap) and makes it possible to detect the exact location of the perforating branches with their cutaneous distribution. This preoperative evaluation, pointing out vascular pathologies which contra-indicate the use of rectus abdominis flap, can be considered a great help for the reconstructive surgeon in the choice of the operative procedure and can surely lead to a significant decrease in postoperative complication rate.

Colour flow duplex scanning: an accurate, non-invasive technique for preoperative evaluation of the vascular supply of the rectus abdominis myocutaneous flap.

Forty patients were examined with colour Doppler to study the vascularization of rectus abdominis myocutaneous flaps before operations. The accuracy of this non-invasive ultrasound technique allowed us to describe the characteristics of the blood flow, including volume and velocity, diameter of vessels and their transverse section area within the epigastric arteries which supply the superior and inferior vascular pedicles of the flap. Vessels are drawn on the skin surface so that the flap can be more precisely and rapidly dissected. We are now using colour Doppler to assess variations in the diameter of vessels and in other variables of blood flow within the vascular pedicle of the transferred flap. These evaluations before and after operation are a great help to the reconstructive surgeon in the choice of operation and will lead to an appreciable reduction in postoperative morbidity.

Preoperative and postoperative evaluation of latissimus dorsi myocutaneous flap vascularization by color flow duplex scanning.

At the Plastic and Reconstructive Surgery Department of the University of Perugia, 104 patients have been examined by color flow duplex scanning in order to study latissimus dorsi vascular supply before and after surgical procedures. This noninvasive ultrasound technique provides a precise and accurate measurement of blood flow velocity (15 cm/s) and volume (27 ml/min) within the thoracodorsal artery, which represents the vascular pedicle of the flap, and it allows us to detect the exact location of the perforating branches with their cutaneous distribution. This preoperative evaluation, pointing out vascular pathologies that contraindicate use of the latissimus dorsi flap, can be considered a great help for the reconstructive surgeon in the choice of the most suitable operation, and it can surely lead to a significant decrease in postoperative graft failure rates.
