A new autologous venous valve by intimal flap. One case report.

Various surgical techniques have been proposed for the treatment of chronic venous insufficiency of post-thrombotic recanalized deep veins of the lower limbs. The preferable method seems to be represented by intravenous valvuloplasty except for the cases affected by extensive valvular damage. For this reason some experimental autologous, heterologous and prosthetic venous valves have been proposed. Such a problem emerged for 1 patient (male, aged 78 years, right limb, leg dystrophy, multiple ulcerations at the ankle) which was selected by duplex, Doppler venous pressure index, photoplethysmography and ascending phlebography. An iliac-femoral and popliteal post-thrombotic, recanalized, decompensated venous insufficiency and one Cockett's perforator incompetence were diagnosed (CEAP classification: C6s Es As2d14 Pr). A bicuspid apparently repairable popliteal valve was detected by phlebography. A traditional intravenous valvuloplasty was planned but the valve was not found at surgical exploration. A monocuspid valve reconstruction by intimal flap vein was performed. The following results were obtained and controlled after one year: stable ulceration healing, dystrophy reduction, improvement in the quality of life, normalization of the hemodynamic parameters and of the radiological morphology of the new valve. It can be concluded that monocuspid valvular repair by intimal flap can be successfully performed in cases affected by secondary valveless deep venous insufficiency of the lower limbs.

Isolated lesion of the medial orbital wall following endonasal surgery. Isolated fractures of the medial orbital wall.

BACKGROUND: Isolated fractures of the medial orbital wall are infrequent. The diagnostic triad includes: adduction block, exotropia with diplopia in all directions of gaze, positive passive duction in abduction. Sometimes a slight enophthalmos is present. Computed tomography shows the extension and the seat of the fracture. CASE REPORT: The authors illustrate the case of a 60 year old male who presented with a breach of the medial orbital wall following endonasal surgery. RESULTS: The patient was successfully operated using an iliac bone graft inserted via an eyebrow-nasal cutaneous approach, after a previous attempt with a transconjunctival approach performed in another hospital had failed. A good functional and aesthetic result was observed within the first year after surgery. After almost 11 years a full adduction is still present and diplopia is absent. CONCLUSION: The authors underline the importance of an early diagnosis and prompt surgical treatment. The fat-muscle entrapment should be removed and the bone defect closed. A close cooperation between ophthalmologist and plastic surgeon is suggested.

[Tissue expansion in head and neck regions]. / L'espansione tissutale nell'estremo cefalico.

The Authors describe their experience with the use of 56 tissue expanders implanted in the head and neck regions of 45 patients observed in a follow-up of an average of 25 months. They emphasize the various possibilities of reconstructive surgery with the use of tissue expanders and the different mental approach required in order to organize surgical when this technique is employed. The criteria used in the selection of the type of tissue expanders is outlined and useful advice concerning the formulation of a surgical plan which employs the most favourable approach in making to avoid poor functional or aesthetic results or secondary complications is presented. Furthermore the surgical technique used to obtain adequate pockets for the insertion of tissue expanders in the different anatomical areas of the head and neck is described. The Authors affiem that in order to avoid damage to the surrounding neurovascular structures and to obtain good tissue expansion, the correct level of dissection is imperative. The options of using different anatomical areas during reconstructive surgery are discussed. For example, the insertion of a tissue expander in the forehead permits the availability of a large amount of usable tissue during nasal reconstruction, thus leaving the donor area without tension and with minimal scarring. Many different causes of baldness can be treated with the use of tissue expanders, such as posttraumatic injury, burns or infections. Tissue expansion can be utilized in the cheek area for the reconstruction of the lower eyelids, the paranasal and the mandibular area. Tissue expanders used in the cervical area can be utilized for reconstructive surgery of the lower lip or the mandibular area. In addition, the Authors discuss possible complications of this technique such as infection, suture distension and tissue expander extrusion. Recommendations are discussed in order to prevent these major complications. Having reviewed their personal experience the Authors feel they can confirm the reliability of this revolutionary technique in the field of plastic and reconstructive surgery. The use of tissue expanders permits the surgeon to obtain improved functional and aesthetic results which only a few years ago were not conceivable.

Recurrent basal cell carcinoma of the back infiltrating the spine. Recurrent basal cell carcinoma.

BACKGROUND: Risk of basal cell carcinoma (BCC) recurrence appears to be related to tumor location, tumor size, treatment modality, radicalness of excision, and histologic type. Recurrences of BCC on the trunk and extremities are rare, with 97% of all recurrent lesions being located in the head and neck region. OBJECTIVE: This report concerns a man who had a BCC of the back removed with electrodesiccation and curettage in 1980 at the age of 36. In the following 10 years the patient experienced five recurrences and finally developed infiltration of the thoracic spine that precluded further attempts at radical excision of the neoplasm. METHODS AND RESULTS: The pathology of the BCC in our patient revealed a number of histologic features that have been associated with aggressive behaviour. These include an infiltrative growth pattern characterized by an irregular and acute tapered profile of the tumor cell groups and fibroblast-rich stroma, infiltrating invading tumour edges, poorly peripheral palisading, nuclear pleomorphism, and perineural invasion. CONCLUSION: Basal cell carcinomas that occur in sunlight-protected areas of the trunk of middle-aged individuals can occasionally exhibit aggressive and highly invasive features as well as a marked tendency for local uncontrollable recurrences. The prognosis for patients with this variety of BCC is poor, especially when progressive infiltration of deep tissues does not permit, as in our case, any possible further radical surgical procedure.

Reduction mammaplasty and correction of ptosis: a personal technique.

New upper pedicle reduction mammaplasty and mastopexy techniques are presented. The surgical steps are described point by point. An analysis is made of the results obtained in 25 patients who underwent surgery between November of 1987 and November of 1988 and were examined in December of 1990 with a mean follow-up of 31.5 months. An assessment was made of the postoperative ptosis, which was minimal in 76 percent of patients. The overall assessment of breasts was satisfactory (good mammary morphology and a correct position of the nipple-areola complex). Nipple-areola complex sensitivity was unchanged in 80 percent of patients. Good-quality inframammary scars were observed in 92 percent of patients, with scar length never exceeding 4 cm. The overall complication rate was 32 percent, but only 12 percent were major complications. The technique presented is excellent when the quantity of glandular tissue to be removed is less than 400 gm, and it is not therefore recommended for gigantomasties.

Treatment of orthognathic problems related to scleroderma.

Scleroderma is a generalized disorder characterized by abnormalities of the small arteries and vasculature resulting in thickening and prominent fibrosis of the affected tissues. Its etiology remains uncertain. All connective tissue and certain internal organs, notably the gastrointestinal tract, heart, lung, and kidneys, as well as skin, are typically involved. Mandibular movement can become severely restricted when the facial skin is affected, sometimes resulting in secondary changes to both the mandible itself and the temporomandibular joint. We present 2 cases in which we improved facial aesthetics and mandibular function by surgically correcting malocclusion with a Le Fort I osteotomy and maxillary intrusion in patients with manifestations of scleroderma in the face and neck.

Craniopagus twins. An unsuccessful separation and a clinical review of the entity.

Craniopagus twinning is an extremely uncommon birth defect with an estimated incidence of 4-6 every 10 million births. The most complex and challenging issue is the feasibility of surgical separation, which involves not only technical but also socioethical problems and requires strict multidisciplinary cooperation between pediatricians, neuroradiologists, anesthesiologists, and plastic and neurological surgeons. The authors report a case in which separation was followed by the death of both twins and stress the importance, from the surgical and prognostic viewpoints, of the degree of vascular connections between the major dural sinuses. We propose a classification into three types according to severity.

Arthrography in the investigation of persistent pain after meniscectomy.

The authors report 62 patients in whom arthrography of the knee had been performed because of persistent pain after menisectomy. In about 60% of the cases the interval between operation and arthrography was less than 18 months. The causes of residual pain identified by arthrography were divided into meniscal and extra meniscal. The most frequent findings were remnants of pathological meniscal tissue; lesions of the anterior cruciate ligament; synovial and chondral pathology. Thirty patients were checked by arthroscopy and were subjected to further operation. In 80% of these cases the arthrographic findings corresponded exactly with the operative findings. The writers confirm that arthrography is still a valid method of investigation in patients affected by persisting pain after meniscectomy.

Evaluation of double contrast arthrography in pigmented villonodular synovitis of the knee.

The authors report the arthrographic findings in 9 cases of diffuse villonodular pigmented synovitis of the knee in various phases of development before and after synovectomy. Arthrography was negative in only one case, while in the other cases the findings were significant but not pathognomonic.

Value and limitations of electro-myography and of radiculography in the diagnosis of lumbar disc hernia (retrospective analysis of 150 cases operated on).

With the object of evaluating the accuracy of electro-myography and of radiculography in the diagnosis of prolapsed intervertebral disc, the writers carried out a critical review of 150 cases operated on with positive findings, in which both the above investigations had been performed preoperatively.

[Anesthesiological problems in maxillo-facial surgical interventions and reconstructive plastic surgery]. / Problemi di anestesiologia negli interventi di chirurgia maxillo-facciale e plastica ricostruttiva.

11 years of anaesthesiological experience in maxillofacial and reconstructive plastic surgery (1-4-1966/1-4-1977) are reviewed. The problems connected with these operations are examined. On the basis of localizations, types of operation and surgical requirements, the problems of greatest importance in these branches of surgery may be indicated in the following 5 parameters: 1. Control of the respiratory ways with naso-tracheal intubation under direct view or blind (more than a thousand cases), oro-tracheal intubation: their indications and contraindications as alternatives to pre- intra- and postoperative tracheotomy. 2. Local control of bleeding. 3. Arousal and prevention of possible postnarcotic complications. 4. Prevention and treatment of postoperative oedema. 5. Nutrition of the patient undergoing surgery. In the interests of history, the superseded problem of whether to use local anaesthesia and general anaesthesia in maxillofacial surgery is mentioned and the various problems are discussed exhaustively. Personal anaesthesiological conduct is then specified in relation to the parameters examined and results reported. The importance in certain endo- and extraoral operations of prolonged intubation in the immediate postoperative period (10-15-30 hours) with respect to the indication for postoperative tracheostomy is highlighted. Apart from certain special pathological situations, tracheostomy is rather exceptional and is no longer employed on a routine basis as it was 2-3 years ago.
