- Prostatic Arterial Embolization versus Transurethral Resection of the Prostate for Benign Prostatic Hyperplasia(2015) BILHIM, Tiago; BAGLA, Sandeep; SAPOVAL, Marc; CARNEVALE, Francisco Cesar; SALEM, Riad; GOLZARIAN, Jafar
- Radiodermitis After Prostatic Artery Embolization: Case Report and Review of the Literature(2015) LABORDA, Alicia; ASSIS, Andre Moreira De; IOAKEIM, Ignatios; SANCHEZ-BALLESTIN, Maria; CARNEVALE, Francisco Cesar; GREGORIO, Miguel Angel DeProstate artery embolization (PAE) is a technically demanding new treatment option for benign prostatic hyperplasia. We present a case of radiation-induced dermitis in a 63-year-old patient after a technically successful PAE, due to high radiation exposure (KAP: 8,023,949 mGy cm(2)) and long fluoroscopy time (72 min). Anatomical and technical aspects are discussed, as well as recommendations to decrease radiation exposure in these procedures.
- Prostatic Artery Embolization for Treatment of Benign Prostatic Hyperplasia in Patients with Prostates > 90 g: A Prospective Single-Center Study(2015) ASSIS, Andre Moreira de; MOREIRA, Airton Mota; RODRIGUES, Vanessa Cristina de Paula; YOSHINAGA, Eduardo Muracca; ANTUNES, Alberto Azoubel; HARWARD, Sardis Honoria; SROUGI, Miguel; CARNEVALE, Francisco CesarPurpose: To describe the safety and efficacy of prostatic artery embolization (PAE) with spherical microparticles to treat lower urinary tract symptoms associated with benign prostatic hyperplasia in patients with prostate volume > 90 g. Materials and Methods: This prospective, single-center, single-arm study was conducted in 35 patients with prostate volumes ranging from 90-252 g. Mean patient age was 64.8 years (range, 53-77 y). Magnetic resonance imaging, uroflowmetry, and the International Prostate Symptom Score (IPSS) were used to assess clinical and functional outcomes. Results: Mean prostate size decreased significantly from 135.1 g before PAE to 91.9 g at 3 months of follow-up (P < .0001). Mean IPSS and quality-of-life index improved from 18.3 to 2.7 and 4.8 to 0.9 (P < .0001 for both), respectively. A significant negative conelation was observed between prostate-specific antigen at 24 hours after PAE and IPSS 3 months after PAE (P = .0057). Conclusions: PAE is a safe and effective treatment for lower urinary tract symptoms secondary to benign prostatic hyperplasia in patients with prostate volume > 90 g. Excessively elevated prostate-specific antigen within 24 hours of PAE is associated with; lower symptom burden in short-term follow-up.
- Pelvic Arterial Anatomy Relevant to Prostatic Artery Embolisation and Proposal for Angiographic Classification(2015) ASSIS, Andre Moreira de; MOREIRA, Airton Mota; RODRIGUES, Vanessa Cristina de Paula; HARWARD, Sardis Honoria; ANTUNES, Alberto Azoubel; SROUGI, Miguel; CARNEVALE, Francisco CesarTo describe and categorize the angiographic findings regarding prostatic vascularization, propose an anatomic classification, and discuss its implications for the PAE procedure. Angiographic findings from 143 PAE procedures were reviewed retrospectively, and the origin of the inferior vesical artery (IVA) was classified into five subtypes as follows: type I: IVA originating from the anterior division of the internal iliac artery (IIA), from a common trunk with the superior vesical artery (SVA); type II: IVA originating from the anterior division of the IIA, inferior to the SVA origin; type III: IVA originating from the obturator artery; type IV: IVA originating from the internal pudendal artery; and type V: less common origins of the IVA. Incidences were calculated by percentage. Two hundred eighty-six pelvic sides (n = 286) were analyzed, and 267 (93.3 %) were classified into I-IV types. Among them, the most common origin was type IV (n = 89, 31.1 %), followed by type I (n = 82, 28.7 %), type III (n = 54, 18.9 %), and type II (n = 42, 14.7 %). Type V anatomy was seen in 16 cases (5.6 %). Double vascularization, defined as two independent prostatic branches in one pelvic side, was seen in 23 cases (8.0 %). Despite the large number of possible anatomical variations of male pelvis, four main patterns corresponded to almost 95 % of the cases. Evaluation of anatomy in a systematic fashion, following a standard classification, will make PAE a faster, safer, and more effective procedure.
