Photodynamic therapy with verteporfin for subfoveal choroidal neovascularization secondary to toxoplasmic chorioretinal scar.

BACKGROUND: To assess the effect of photodynamic therapy in the treatment of subfoveal choroidal neovascularization consecutive to a toxoplasmic chorioretinal scar. HISTORY AND SIGNS: Three patients with a previous history of toxoplasmic chorioretinal scar noticed a decrease in visual acuity and metamorphopsia. Fundus examination and fluorescein angiography revealed the presence of subfoveal choroidal neovascularization at the edge of the toxoplasmic chorioretinal scar. THERAPY AND OUTCOME: The first patient, aged 78, was treated by photodynamic therapy followed by three subsequent treatments of feeder vessel by laser photocoagulation. Visual acuity decreased during follow-up in the presence of recurrence of choroidal neovascularization and subretinal fibrosis. The second patient, a 20-year-old lady, was treated with three sessions of photodynamic therapy for a subfoveal choroidal neovascularization related to a toxoplasmic scar. Visual acuity was stabilized on the last follow-up visit at 0.3. The third patient, aged 53, received four treatments with photodynamic therapy at an interval of 3 - 4 months. choroidal neovascularization was stabilized and the last visual acuity was 0.2. CONCLUSIONS: This preliminary report suggests that photodynamic therapy with verteporfine may be an effective therapeutic modality for subfoveal choroidal neovascularization related to a toxoplasmic chorioretinal scar. Further assessment is needed in order to confirm this preliminary findings.

Feasibility of intraoperative balloon angioplasty and additional stent placement of isolated stenosis of the brachiocephalic trunk.

OBJECTIVE: We sought to evaluate the feasibility and results of intraoperative balloon angioplasty and additional stent placement of isolated stenosis of the brachiocephalic trunk. PATIENTS AND METHODS: Between May 1993 and October 1996, we treated eight patients with local stenosis of the innominate artery. Seven lesions were situated in the proximal and one in the middle third of the brachiocephalic trunk. Five patients were men and three were women, with ages ranging from 55 to 72 years (mean 59.5 years). All stenoses provoked severe blood flow reduction and caused clinical symptoms. Procedures were performed in an operating suite with fluoroscopic imaging capabilities. Through an anterolateral cervical approach the right common carotid artery was surgically exposed and then clamped to avoid atheroembolization during the subsequent procedure. Retrograde catheterization was performed to reach the stenosis of the brachiocephalic trunk. The lesion was dilated with a balloon catheter and successively stented. Follow-up examinations (color-coded duplex sonography, accompanied by clinical inspection and systolic blood pressure) were scheduled every 6 months. RESULTS: In all patients the dilation of the stenosis of the innominate artery and the stent placement were successful without any side effects. No embolic events or other complications occurred. The postintervention angiography showed successfully dilated stenoses and patent stents in all cases. The technical success rate was 100%. CONCLUSIONS: On the basis of our preliminary data, we believe that, in selected patients, intraoperative balloon angioplasty of stenosis of the innominate artery with stent placement from the right common carotid artery approach is a safe and effective alternative to conventional operations.

[Peripheral nerve injuries during carotid endarterectomy].

Our experience with patients undergoing carotid endoarteriectomy over a 10 year period has been retrospectively reviewed. Nerve injuries were detected by reviewing postoperative progress and clinical notes. One hundred thirty-four procedures were performed on 120 patients, to 15 of whom (9%) occurred major nerve injuries. These included seven vagal nerve injuries causing ipsilateral vocal cord paralysis and hoarseness, five injuries of the marginal mandibular nerve and three injuries of the hypoglossal nerve. None of the patients with nerve injury had a stroke as a result of carotid operation. Vocal cord paralysis was documented by laryngoscopy. The incidence of cranial nerve injury during carotid endoarteriectomy appears to be higher than expected, particularly if asymptomatic patients are controlled.

[Clinical aspects of persistent sciatic artery. Description of 2 cases with angiographic demonstration].

We report 2 additional cases with angiographic demonstration. The embryology and radiological findings are discussed. This anomaly should be kept in mind in the clinical assessment of a patient with unexplained sciatic or buttock pain or a pulsatile buttock mass with or without symptoms of peripheral vascular disease. It also represents a potential hazard during renal transplant surgery.

[A case of giant lumbar neurinoma].

A rare case of a giant extradural neurinoma of the IV lumbar root with an anterior development and a soft neurological picture is reported. The Authors stress the important role of CT both in the neurinoma diagnosis and in the correct preoperative evaluation of its extension and its relationship with contiguous organs.

[Computed tomography and pneumoconioses].

In the last two decades the use of Computed Tomography (CT) has played an important role in the diagnosis of pneumoconioses because of its spatial resolution and lack of technical limitations if compared to traditional chest radiography, first of all in the early stages. Nevertheless the staging of these diseases is still based on the International Labour Office (ILO) classification issued in 1980, whose application is obtained comparing radiographical findings with a standard set of radiographs provided by ILO itself. Starting from the early nineties many studies attempted to propose a classification system similar to the ILO one, combining different symbols to describe a CT thoracic finding or introducing a "score system" to classify different CT patterns (fibrosis, pleural plaques, etc.) and their severity. Despite these efforts no classification system has been accepted yet. After a short description of technical and practical issues of using CT in the diagnosis of pneumoconioses, this article aims at summarizing different classification attempts.

[Thrombosis of the renal vein after transplantation. Description of a case].

The Authors report a case of renal vein thrombosis after kidney transplantation, which occurred early in the postoperative period and was treated successfully. The treatment is described as are the factors contributing to the good result: early diagnosis and surgical procedure, removal of the transplant and perfusion with cold heparin solution through the artery and the vein, reconstruction of a new vein to vein anastomosis, in a more favorable site.
