Exenteration of the orbit is a disfiguring and destructive procedure; it is generally performed for orbital malignancies and often provides a significant reconstructive challenge. Our purpose was to evaluate the clinical indications for orbital exenteration in a tertiary referral center and to assess the reconstructive options employed. A retrospective nonrandomized analysis was performed, selecting all patients undergoing orbital exenteration over a 5-year period, between January 2005 and January 2010. Patient demographics, tumor characteristics, and reconstructive techniques used were evaluated. Twenty patients with a mean age of 76.5 years underwent total orbital exenteration. Basal cell carcinoma was the main operative indication (45%), followed by squamous cell carcinoma (15%). Reconstructive techniques included cover of the raw orbital cavity with a temporal muscular flap in all cases followed with split skin grafting (25%), bilaterally pedicle V-Y advancement flap (10%) and a fasciocutaneous island flap of the retroauricular region (65%). Twenty percent of patients had local complications and all were treated in a satisfactory fashion. Eyelid skin tumors remain an important cause of orbital exenteration. Temporal muscle flap is a reliable and stable reconstructive solution after orbital exenteration and additional aid is supplied with skin grafts or local flaps. This technique ensures a good aesthetic outcome and better situation for later complementary treatments and minimal associated donor site morbidity.

A atrésia pulmonar com septo interventricular intacto (AtrP-SI) é uma cardiopatia congénita rara e de prognóstico reservado. Apresenta grande variabilidade anatómica, com diversos graus de hipoplasia do ventrículo direito (VD) o que condiciona a abordagem terapêutica. Idealmente, o objectivo é a reconstituição de uma circulação de tipo biventricular. Para o efeito, dispomos de técnicas cirúrgicas e percutâneas. A perfuração da válvula pulmonar com energia de radiofrequência (RF) é um método válido para doentes com atresia de tipo membranoso, VD sem hipoplasia marcada (bipartido ou tripartido) e circulação coronária não dependente do VD. Por vezes, há necessidade de suplementar a circulação pulmonar implantando um stent no canal arterial. Desta forma é possível tratar alguns doentes com técnicas exclusivamente percutâneas. Relatamos o primeiro caso conhecido em Portugal de um recém-nascido com AtrP-SI submetido a perfuração com radiofrequência e, num segundo tempo, implantação de stent no canal arterial.
