Angioplastia das Artérias do Sector Aorto-Ilíaco

Efectuou-se angioplastia transluminal percutânea (ATP) do sector aorto-ilíaco em 92 doentes, com lesões de aterosclerose. Conseguiu-se um sucesso inicial de 87,8% e um sucesso tardio de 69,4%. Os resultados tardios foram avaliados objectivamente em 58 doentes, 36 dos quais foram estudados por Angiografia e os restantes por Doppler. Houve complicações em 6,6% dos doentes das quais 2,8% eram graves tendo sido necessária intervenção cirúrgica. A mortalidade foi nula. Os bons resultados iniciais e tardios, a baixa morbilidade e a mortalidade nula levam-nos a concluir que a ATP é um bom método de revascularização altamente eficaz. Os melhores resultados obtiveram-se em doentes sintomáticos com estenose ou oclusão curta e significativa.

Angioplastia das Artérias do Sector Femoro-Popliteo

Efectuámos angioplastia transiuminal percutânea (ATP) em 66 doentes do sector fémoro-popliteo com lesões de aterosclerose, e obtivemos um sucesso clínico inicial de 80,3% e um sucesso tardio de 60,7%. Conseguimos melhores resultados iniciais e tardios nos doentes que tinham boa circulação a jusante. As diferenças foram significativas. Houve complicações graves que necessitaram de intervenção cirúrgica em 3,4% dos doentes. A mortalidade foi nula. Estes resultados mostram que a ATP é uma técnica de intervenção útil no tratamento de lesões obstrutivas do sector fémoro-popliteo.

Prostate Cancer: The Role of Multiparametric Magnetic Resonance Imaging

Multiparametric Magnetic Resonance Imaging has been increasingly used for detection, localization and staging of prostate cancer over the last years. It combines high-resolution T2 Weighted-Imaging and at least two functional techniques, which include Dynamic Contrast–Enhanced Magnetic Resonance Imaging, Diffusion-Weighted Imaging, and Magnetic Resonance Imaging Spectroscopy. Although the combined use of a pelvic phased-array and an Endorectal Coil is considered the state-of-the-art for Magnetic Resonance Imaging evaluation of prostate cancer, Endorectal Coil is only absolute mandatory for Magnetic Resonance Imaging Spectroscopy at 1.5 T. Sensitivity and specificity levels in cancer detection and localization have been improving with functional technique implementation, compared to T2 Weighted-Imaging alone. It has been particularly useful to evaluate patients with abnormal PSA and negative biopsy. Moreover, the information added by the functional techniques may correlate to cancer aggressiveness and therefore be useful to select patients for focal radiotherapy, prostate sparing surgery, focal ablative therapy and active surveillance. However, more studies are needed to compare the functional techniques and understand the advantages and disadvantages of each one. This article reviews the basic principles of prostatic mp-Magnetic Resonance Imaging, emphasizing its role on detection, staging and active surveillance of prostate cancer.

Post-Treated Prostate Cancer: Normal Findings and Signs of Local Relapse on Multiparametric Magnetic Resonance Imaging

The use of multiparametric magnetic resonance imaging (mp-MRI) for prostate cancer has increased over recent years, mainly for detection, staging, and active surveillance. However, suspicion of recurrence in the set of biochemical failure is becoming a significant reason for clinicians to request mp-MRI. Radiologists should be able to recognize the normal post-treatment MRI findings. Fibrosis and atrophic remnant seminal vesicles after prostatectomy are often found and must be differentiated from local relapse. Moreover, brachytherapy, external beam radiotherapy, cryosurgery, and hormonal therapy tend to diffusely decrease the signal intensity of the peripheral zone on T2-weighted images (T2WI) due to the loss of water content, consequently mimicking tumor and hemorrhage. The combination of T2WI and functional studies like diffusion-weighted imaging and dynamic contrast-enhanced improves the identification of local relapse. Tumor recurrence tends to restrict on diffusion images and avidly enhances after contrast administration either within or outside the gland. The authors provide a pictorial review of the normal findings and the signs of local tumor relapse after radical prostatectomy, external beam radiotherapy, brachytherapy, cryosurgery, and hormonal therapy.
