RESUMO

Background and Objectives: Lower extremity lymphedema (LEL) is one of the most relevant chronic and disabling sequelae after gynecological cancer therapy involving pelvic lymphadenectomy (PL). Supermicrosurgical lymphaticovenular anastomosis (LVA) is a safe and effective procedure to treat LEL, particularly indicated in early-stage cases when conservative therapies are insufficient to control the swelling. Usually, preoperative assessment of these patients shows patent and peristaltic lymphatic vessels that can be mapped throughout the limb to plan the sites of skin incision to perform LVA. The aim of this study is to report the efficacy of our approach based on planning LVA in three areas of the lower limb in improving early-stage gynecological cancer-related lymphedema (GCRL) secondary to PL. Materials and Methods: We retrospectively reviewed the data of patients who underwent LVA for the treatment of early-stage GCRL following PL. Patients who had undergone groin dissection were excluded. Our preoperative study based on indocyanine green lymphography (ICG-L) and color doppler ultrasound (CDU) planned three incision sites located in the groin, in the medial surface of the distal third of the thigh, and in the upper half of the leg, to perform LVA. The primary outcome measure was the variation of the mean circumference of the limb after surgery. The changes between preoperative and postoperative limbs' measures were analyzed by Student's t-test. p values < 0.05 were considered significant. Results: Thirty-three patients were included. In every patient, three incision sites were employed to perform LVA. A total of 119 LVA were established, with an average of 3.6 for each patient. The mean circumference of the operated limb showed a significant reduction after surgery, decreasing from 37 cm ± 4.1 cm to 36.1 cm ± 4.4 (p < 0.01). Conclusions: Our results suggest that in patients affected by early-stage GCRL secondary to PL, the placement of incision sites in all the anatomical subunits of the lower limb is one of the key factors in achieving good results after LVA.

RESUMO

BACKGROUND AND AIMS: Percutaneous cholangioscopy (PC) is more complex and invasive than a transpapillary approach, with the need for a large percutaneous tract of 16 French (Fr) on average in order to advance standard percutaneous cholangioscopes. The aim of this study was to investigate whether percutaneous single-operator cholangioscopy (pSOC) using the SpyGlass™ DS system is feasible, safe, and effective in PC for diagnostic and therapeutic indications. MATERIALS AND METHODS: The data of 28 patients who underwent pSOC in 4 tertiary referral centers were retrospectively analyzed. Technical and clinical success for therapeutic procedures was assessed as well as diagnostic accuracy of pSOC-guided biopsies and visualization. Adverse events and the required number and size of dilatations were reviewed. RESULTS: 25/28 (89%) patients had a post-surgical altered anatomy. The average number of percutaneous dilatations prior to pSOC was 1.25 with a mean dilatation size of 11 French. Histopathology showed a 100% accuracy. Visual impression showed an overall accuracy of 96.4%. Technical and clinical success was achieved in 27/28 (96%) of cases. Adverse events occurred in 3/28 (10.7%) cases. CONCLUSION: pSOC is a feasible, safe, and effective technique for diagnostic and therapeutic indications. It may be considered an alternative approach in clinical cases where gastrointestinal anatomy is altered. It has the potential to reduce peri-procedural adverse events and costs. Prospective randomized-controlled trials are necessary to confirm the previously collected data.

RESUMO

The European Society of Gynaecological Oncology (ESGO) developed and established for the first time in 2016, and updated in 2020, quality indicators for advanced ovarian cancer surgery to audit and improve clinical practice in Europe and beyond. As a sequela of the continuous effort to improve oncologic care in patients with ovarian cancer, ESGO issued in 2018 a consensus guidance jointly with the European Society of Medical Oncology addressing in a multidisciplinary fashion 20 selected key questions in the management of ovarian cancer, ranging from molecular pathology to palliation in primary and relapse disease. In order to complement the above achievements and consolidate the promoted systemic advances and surgical expertise with adequate peri-operative management, ESGO developed, as the next step, clinically relevant and evidence-based guidelines focusing on key aspects of peri-operative care and management of complications as part of its mission to improve the quality of care for women with advanced ovarian cancer and reduce iatrogenic morbidity. To do so, ESGO nominated an international multidisciplinary development group consisting of practicing clinicians and researchers who have demonstrated leadership and expertise in the care and research of ovarian cancer (18 experts across Europe). To ensure that the guidelines are evidence based, the literature published since 2015, identified from a systematic search, was reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the development group. The guidelines are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines were reviewed by 117 independent international practitioners in cancer care delivery and patient representatives.

RESUMO

PURPOSE: Parastomal recurrence of squamous cell carcinoma (SCC) with tracheal involvement following salvage total laryngectomy after prior concurrent chemoradiotherapy is one of the most insidious challenges in head and neck surgery because a complex reconstruction is often required for covering a large area of skin loss, filling the dead space beneath, tracheal reconstruction and suspension, and tracheostome resurfacing. The aim is to describe our experience with the internal mammary artery perforator (IMAP) propeller flap for tracheal and tracheostome reconstruction and neck resurfacing after parastomal and cervical trachea resection, especially for suspension and anchoring the stump of the residual distal trachea to the island flap itself. METHODS: We describe IMAP flap reconstruction after resection of parastomal recurrence of SCC requiring cervical trachea resection in five patients between January 1, 2005 and August 30, 2019. RESULTS: IMAP propeller flap was successfully used for reconstruction after complex resection of parastomal recurrence of SCC with cervical trachea involvement in all cases. The mean length and width were, respectively, 16.8 cm (range 13-23) and 6.9 cm (range 5.5-8). We did not report complications of both the donor and the recipient site. Pharyngo-cutaneous or tracheoesophageal fistulas and wound dehiscence were not observed. CONCLUSIONS: to the best of our knowledge, this is the first report about the use of the IMAP propeller flap in this more complex clinical setting and we provide the message that this surgical procedure is worthy of consideration.

RESUMO

OBJECTIVE: We investigated the accuracy of digital breast tomosynthesis compared to full-field digital mammography for evaluating tumor-free resection margins in the intraoperative specimen during breast-conserving surgery, reducing re-excision rates. MATERIALS AND METHODS: In total, 170 patients, with proven breast cancer and eligible for breast-conserving surgery, were enrolled. Intraoperative specimens underwent digital mammography and digital breast tomosynthesis. Two breast radiologists, with ten years of experience in breast imaging, in batch mode, evaluated tumor-free resection margins and the distance between the margins and lesion. Histopathological findings were considered the standard of reference. RESULTS: We used the correlation analysis to evaluate the agreement between measures of tumor-free resection margins obtained with digital mammography and the true value (histopathological findings), and between digital breast tomosynthesis and histopathological findings. The size evaluation determined by digital breast tomosynthesis was more accurately correlated with that found by pathology; the calculated Pearson's correlation coefficient of digital breast tomosynthesis and digital mammography to the pathologically determined tumor-free resection margins were 0.92 and 0.79 in CC view and 0.92 and 0.72 in LL view, respectively. Compared with the pathologically determined tumor-free resection margins, the size determined by both imaging modalities was, on average, overestimated. Bland-Altman analysis showed an excellent inter readers agreement. CONCLUSIONS: Digital breast tomosynthesis is more accurate in assessment of margin status than digital mammography; it could be a more accurate technique than full-field digital mammography for the intraoperative delineating of tumor resection margins.

RESUMO

BACKGROUND: Cardiovascular complications represent the major cause of morbidity and mortality of type 2 diabetes mellitus (T2DM) patients. In particular, peripheral artery disease (PAD) represents a frequent T2DM vascular complication and a risk factor for the development of major adverse cardiovascular events (MACE). Among adipokines, omentin-1 serum levels are reduced in T2DM patients with PAD and are inversely related to disease severity. OBJECTIVE: To study the relationship between omentin-1 levels, at baseline, with outcomes after endovascular procedures in T2DM patients with PAD and chronic limb-threatening ischemia (CLTI). RESEARCH DESIGN AND METHODS: We enrolled for our prospective non-randomized study, 207 T2DM patients with PAD and CLTI, requiring revascularization. Omentin-1 serum levels were collected before revascularization and patients incidence outcomes were evaluated at 1, 3, 6 and 12 months. RESULTS: Omentin-1 was reduced in patients with more severe disease (27.24 ± 4.83 vs 30.82 ± 5.48 ng/mL, p < 0.001). Overall, 84 MACE and 96 major adverse limb events (MALE) occurred during the 12-month follow-up. We observed that omentin-1 levels were lower in patients with MACE (26.02 ± 4.05 vs 31.33 ± 5.29 ng/mL, p < 0.001) and MALE (26.67 ± 4.21 vs 31.34 ± 5.54 ng/mL, p < 0.001). The association between omentin-1, MACE and MALE remained significant after adjusting for major risk factors in a multivariate analysis. Receiver operating characteristics (ROC) curve using omentin-1 levels predicted incidence events (area under the curve = 0.80). CONCLUSIONS: We demonstrated that reduced omentin-1 levels, at baseline, are related with worse vascular outcomes in T2DM patients with PAD and CLTI undergoing an endovascular procedure.

RESUMO

OBJECTIVES: To retrospectively analyze interventional radiology (IR) activity changes in the COVID-19 era and to describe how to safely and effectively reorganize IR activity. METHODS: All IR procedures performed between January 30 and April 8, 2020 (COVID-era group) and the same 2019 period (non-COVID-era group) were retrospectively included and compared. A sub-analysis for the lockdown period (LDP: 11 March-8 April) was also conducted. Demographic, hospitalization, clinical, and procedural data were obtained for both groups and statistically compared with univariable analysis. RESULTS: A total of 1496 procedures (non-COVID era, 825; COVID era, 671) performed in 1226 patients (64.9 ± 15.1 years, 618 women) were included. The number of procedures decreased by 18.6% between 2019 and 2020 (825 vs 671, p < .001), with a reduction by 48.2% in LDP (188 vs 363, p < .0001). In the LDP COVID era, bedside procedures were preferred (p = .013), with an increase in procedures from the intensive care unit compared with the emergency department and outpatients (p = .048), and an increased activity for oncological patients (p = .003). No incidents of cross-infection of non-infected from infected patients and no evidence of COVID-19 infection of healthcare workers in the IR service was registered. CONCLUSIONS: Coronavirus disease outbreak changed the interventional radiology activity with an overall reduction in the number of procedures. However, this study confirms that interventional radiology continuum of care can be safely performed also during the pandemic, following defined measures and protocols, taking care of all patients. KEY POINTS: • Coronavirus disease pandemic determined a reduction of interventional radiology activity as compared to the same period of the previous year. • Interventional radiology procedures for life-threatening conditions and non-deferrable oncologic treatments were prioritized as opposed to elective procedures. • Strict adoption of safe procedures allowed us to have until now no incidents of cross-infection of non-infected from infected patients and no evidence of COVID-19 infection of HCWs in the IR service.

RESUMO

BACKGROUND: The superficial circumflex iliac perforator (SCIP) flap has many ideal features, such as fast dissection, possibility to harvest thin, pliable, wide skin island, and concealed donor site scar. In spite of these features, its use was limited because of the wide anatomical variation of the pedicle, which is relatively shorter and has a smaller caliber than other more popular perforator flaps. Several names were given to the branches and perforators in the literature, thus adding confusion to the understanding of its anatomy. METHODS: We performed a surgical and a radioanatomical study of the SCIP pedicles analyzing high-resolution contrast-enhanced computed tomography (CT) scan of 95 groins, with particular attention to the deep branch (DB) of the superficial circumflex iliac artery (SCIA). Twenty-three of these patients were also studied by detecting the surgical anatomy during SCIP flap harvest. We employed a system of coordinates based on the line between pubic tubercle (PT) and anterior superior iliac spine (ASIS) to describe the position of the perforator of the DB. RESULTS: We found a 100% correlation between surgical and radiological findings. The length of the DB from the origin to the point in which its perforator pierced the sartorius fascia ranged from 1.6 to 6.5 cm, mean = 3.62 ± 0.92 cm. The distance between the origin of the DB and the inguinal ligament ranged from 1.1 to 7.5 cm, mean = 2.8 ± 1 cm. The perforator of the DB could be found in 91% of the cases within a box of 4 cm × 3 cm drawn caudally to the line joining the PT with the ASIS. This vessel can show a vertical or horizontal course in the subcutaneous layer. CONCLUSION: Our findings confirm other previous studies and add new information about the position and the course of the perforator of the DB of the SCIA. Important features of the SCIP pedicles can be investigated by the color Doppler ultrasound and CT scan.

RESUMO

OBJECTIVE: To evaluate effectiveness and safety of UFE as alternative to surgery, in treatment of uterine fibromatosis. METHODS/MATERIALS: 255 patients (aged 26-55) with symptomatic UF, indication for surgery, followed in our center (2000-2014), single or multiple fibroids, pain and/or functional/compressive disorders, underwent embolization: injection of PVA particles (150-900 µm) from distal portion of uterine arteries (ascending section). Primary end-point: flow-stop distally to injection site, disappearance of lesion design, preservation of flow in main trunk of UA. Secondary end-point: control of pain and functional/compressive disorders during follow-up (2-7 years). RESULTS: Procedure was performed bilaterally in 250 patients (98%). Mean duration: 47 min (average fluoroscopy: 10:50 min). Post-embolization pelvic pain (according with VAS score) was on average 2.2 at discharge (24 h). Follow-up at 2 years: resolution of menstrual disorders in 78% of patients and improvement in 14%; pain disappeared in 66%; significant improvement of menstrual flow and HCT/HB levels, decrease in total uterine (57.7%)/dominant fibroid (76.1%) volume. Recurrence in 18 patients. CONCLUSIONS: UFE represents an excellent alternative to surgical treatment: it is safe, tolerable and effective both in short and long term, with evident advantages in economic and social terms.

RESUMO

OBJECTIVE: Groin dissection is the procedure with the highest risk of lower limb lymphedema.As lymph stasis causes irreversible alterations to the limb over time,therapies should be administered in early stages,or better yet, lymphatic drainage impairment should be prevented.We developed a new preventive approach to lymphedema after groin dissection, and we report our preliminary experience. PATIENTS AND METHODS: We enrolled 5 patients undergoing bilateral groin dissection for vulvar cancer. Preoperative study of lower limbs lymphatic function was obtained by lymphoscintigraphy, with lymphatic transport index, indocyanine green (ICG) lymphography, and volume measurement with lower extremity lymphedema (LEL) index calculation. At the end of lymphadenectomy, one groin was closed in the standard way. On the other side, a lymphatic flap pedicled on the distal perforator of the deep branch of the superficial circumflex iliac vessels, was transposed into the groin region. Lymphatic function examination of the limbs was repeated 6 months after surgery. RESULTS: Before surgery no patient showed lymphatic drainage impairment at lymphoscintigraphy or lymphography, LEL index was in every limb lower than 250 (mean: 217.3 ± 13.83). After surgery the limbs treated with the flap showed no pathological swelling, LEL-index < 250 (mean: 235.4 ± 13.069), linear pattern at lymphography, and normal lymphoscintigraphy. The untreated limbs showed from moderate to severe edema with 265 < LEL-index < 310 (mean: 283 ± 16.3), diffuse dermal backflow at lymphography and interruption of lymph flow, with dermal backflow, at lymphoscintigraphy. Mean difference between preoperative and postoperative volumes was 64.8 ± 25.1 in the untreated side and 19 ± 11.7 in the side with the flap. The difference between preoperative and postoperative volumes compared between the treated and untreated side was statistically significant (P < .01). CONCLUSION: Our preliminary evidence suggests that this flap can prevent lymphedema after groin dissection. Further studies are necessary to confirm these results.

RESUMO

BACKGROUND: Multidetector computed tomography angiography (MDCTA) and magnetic resonance angiography (MRA) are accurate techniques for selecting patients with peripheral arterial disease for surgical and endovascular treatment. No studies in the literature have directly compared MDCTA and MRA to establish which one should be employed, in patients suitable for both techniques, before endovascular treatment. PURPOSE: To compare diagnostic performance of MDCTA vs MRA before endovascular intervention. MATERIAL AND METHODS: We prospectively compared MDCTA (64 slices scanner) and MRA (1.5 T scanner; 3D gadolinium-enhanced bolus-chase acquisition plus time resolved acquisition on calves) to stratify 35 patients according to the TASC II score and a runoff severity score. We also evaluated the accuracy of both techniques in each arterial segment. Selective angiography performed during the treatment was the standard of reference. RESULTS: MDCTA and MRA accurately classify disease in the aorto-iliac (accuracy 0.92 for MDCTA and MRA) and femoro-popliteal (MDCTA 0.94, MRA 0.90) segments. MDCTA was more accurate in stratifying disease in the infrapopliteal segments (0.96 vs. 0.9) and in assessing the impairment of runoff arteries (0.92 vs. 0.85) at per-segment analysis. MDCTA showed a higher confidence and a shorter examination time. CONCLUSION: Our results suggest that MDCTA can be considered as a first-line investigation in patients being candidates for endovascular procedures when clinical history or duplex sonographic evaluation are indicative of severe impairment of the infrapopliteal segment.

RESUMO

BACKGROUND: For more than forty years, graftectomy has been the standard treatment of spontaneous renal transplant rupture. However, recent evidences suggest that graft salvage strategies can be safely pursued, even in difficult cases. CASE PRESENTATION: We report on a thirty-nine-year-old woman who received a deceased donor kidney transplant and experienced spontaneous allograft rupture due to acute rejection. The rupture was further complicated by urinary leakage. The kidney and the ureter were successfully repaired. Eight years after transplantation, graft function is still excellent. CONCLUSION: Due to the lack of transplantable organs and the long time usually spent on the waiting list, graftectomy should be only considered in case of refractory haemodynamic instability or compromised graft viability.

RESUMO

For many microsurgeons, antegrade internal mammary vessels (AIMVs) represent the recipients of choice in autogenous breast reconstruction. For the past few years, the retrograde internal mammary vessels (RIMVs) have been demonstrated to be a further reliable option when needed, according to many papers focusing more on the vein than on the artery. Besides the clinical evidence, the hemodynamic features of the retrograde system have been very seldom analyzed.In this article, we report our clinical experience with deep inferior epigastric perforator (DIEP) flaps anastomosed to RIMVs, along with a perioperative radiological follow-up to study RIMVs' hemodynamics and to further support the reliability of the retrograde system with particular focus on the retrograde internal mammary artery.Prospective, preoperative, and postoperative (3 days, 21 days, and 3 months, respectively) color Doppler sonographies of the internal mammary artery (IMA) and DIEPs have been performed to collect the velocity of flow (v) and resistive index (RI) data. Twenty-two patients agreed to undergo this protocol, of which 10 unipedicle flaps were anastomosed to AIMVs ("control" group), 10 bipedicle DIEPs to both AIMVs and RIMVs ("study" group), and 2 DIEPs anastomosed to retrograde internal mammary artery and antegrade internal mammary vein (not statistically analyzed for their paucity). Student t test was performed to compare the "control" and "study" groups.All the flaps survived, and no re-exploration was needed. Internal mammary artery and perforators v showed similar but speculate trend, whereas IMA and perforators RI looked stable during that time. Significant differences have been found in the "study" group for IMA v at 3-day period, for perforator v at 21- and 90-day periods, and for perforator RI at 90-day period, without any clinical implication for flap viability.Retrograde internal mammary vessels can be considered reliable vessels for both arterial flap input and venous flap outflows, either as additional or the sole recipients. However, further and larger studies would be useful to better understand the hemodynamics of the retrograde system.

RESUMO

The anatomy of perforator for anteromedial thigh (AMT) flap is a very much-debated issue. In this article, we report AMT perforator vascular anatomy by CT-Angiography (CTA) evaluation of 68 consecutive healthy thighs. Perforators emergence, caliber, length, course, and source vessel in the central three fifth of the thigh were studied by a virtual coordinate system. A mean 4.94 ± 1.75 perforators per thigh (average length, 2.6 ± 0.99 cm) from superficial femoral artery (SFA) were found, emerging medial and lateral to sartorius muscle. A mean 0.4 ± 0.74 perforators per thigh (average length, 2.45 ± 0.97 cm) branched from rectus femoris artery, of which 80% were emerging lateral to sartorius muscle. A mean 0.62 ± 0.91 perforators per thigh (average length, 3.1 ± 1.23 cm) branched from an unnamed branch of SFA, of which 88% were emerging lateral to the sartorius muscle. Perforators' calibre was inferior to 1-5 mm in 177 perforators (51.6%), between 1.5 and 2 mm in 159 (46.7%), and over 2 mm in 7 (2%). The findings from this study show that AMT region is plenty of reliable perforators with overlapping fascial emergence but branching from three different source arteries.

OBJECTIVES: To investigate the following: (a) effects of intercostal muscle contraction on sonographic assessment of lung sliding and (b) inter-rater and intra-observer agreement on sonographic detection of lung sliding and lung pulse. METHODS: We used Valsalva and Muller maneuvers as experimental models in which closed glottis and clipped nose prevent air from entering the lungs, despite sustained intercostal muscles contraction. Twenty-one healthy volunteers underwent bilateral lung ultrasound during tidal breathing, apnea, hyperventilation, and Muller and Valsalva maneuvers. The same expert recorded 420 B-mode clips and 420 M-mode images, independently evaluated for the presence or absence of lung sliding and lung pulse by three raters unaware of the respiratory activity corresponding to each imaging. RESULTS: During Muller and Valsalva maneuvers, lung sliding was certainly recognized in up to 73.0% and up to 68.7% of imaging, respectively, with a slight to fair inter-rater agreement for Muller maneuver and slight to moderate for Valsalva. Lung sliding was unrecognized in up to 42.0% of tidal breathing imaging, and up to 12.5% of hyperventilation imaging, with a slight to fair inter-rater agreement for both. During apnea, interpretation errors for sliding were irrelevant and inter-rater agreement moderate to perfect. Even if intra-observer agreement varied among raters and throughout respiratory patterns, we found it to be higher than inter-rater reliability. CONCLUSIONS: Intercostal muscles contraction produces sonographic artifacts that may simulate lung sliding. Clinical studies are needed to confirm this hypothesis. We found slight to moderate inter-rater agreement and globally moderate to almost perfect intra-observer agreement for lung sliding and lung pulse.

RESUMO

Background: It is reasonable to place an Inferior Vena Cava Filter (IVCF) when an acute deep vein thrombosis (DVT) of the lower limbs occurs in a patient with absolute contraindication to therapeutic anticoagulation. An additional potential reason for placing an IVCF is the need to stop therapeutic anticoagulation in a patient with acute DVT who must undergo urgent non-deferrable surgery. However, IVCFs are often used outside of such established indications and many authors argue about their actual utility, especially in terms of survival. In this retrospective study, we looked for clinical correlates of in-hospital mortality among patients who underwent IVCF placement, limiting our analysis to the cases for which a correct indication to IVCF placement existed. Methods: We retrospectively analyzed the electronic database of our University Hospital, searching for consecutive hospitalized patients who had acute DVT and underwent IVCF placement because of an established contraindication to therapeutic anticoagulation and/or because it was necessary to stop anticoagulation due to urgent surgery. The search covered the period between 1 January 2010 and 31 December 2020. Results: The search resulted in the identification of 168 individuals. An established contraindication to therapeutic anticoagulation was present in 116 patients (69.0%), while urgent non-deferrable surgery was the reason for IVCF placement in 52 patients (31.0%). A total of 24 patients (14.3%) died during the same hospital stay in which the IVCF was placed. Mortality rate was significantly higher in patients with a contraindication to anticoagulation than in patients who underwent IVCF placement because of urgent surgery (19.0% vs. 3.8%, OD 5.85 vs. 0.17). In-hospital mortality was also significantly higher among patients with chronic kidney disease and those who needed blood cell transfusion during hospitalization. Conclusions: This study provides novel information on clinical correlates of in-hospital mortality among patients with acute DVT who undergo IVCF. Prospective observational studies are needed to substantiate these findings.

RESUMO

BACKGROUND: Penile duplex Doppler ultrasound in combination with intra-cavernous injection of vasoactive agents (PDDU-ICI) is the most accepted tool for diagnosis of arteriogenic erectile dysfunction (AED), but is invasive, time consuming and at risk of side effects. OBJECTIVES: The purpose of this pilot study is to evaluate the potential of transrectal color Doppler ultrasound (TR-CDU) of the common penile arteries as a non-invasive method for the diagnosis of AED. MATERIALS AND METHODS: A consecutive series of 61 men consulting for erectile dysfunction (ED) and 20 controls underwent TR-CDU examination, aged from 40 to 80 years. Sonographic parameters were correlated with the International Index of Erectile Function, short form (IIEF-5). Sensitivity and specificity were calculated and the areas under the receiver operating characteristic curves (AUC) were compared to evaluate the diagnostic performance. RESULTS: Receiver operating characteristic curve analysis showed no significant results for IIEF-5 score ⩾21 in relation to the Doppler parameters. However, we found a good diagnostic performance for patients with ED grading from moderate to severe at IIEF-5. In this cohort, we found that mean peak systolic velocity >15.8 cm/s predicted IIEF-5 ⩾17 (AUC = 0.73, p = 0.002) with 61.5% sensitivity and 85.7% specificity. Mean end diastolic velocity >1.46 cm/s predicted IIEF-5 ⩾17 (AUC = 0.68, p = 0.02) with 80.7% sensitivity and 52.4% specificity. Mean resistance index ⩽0.72 predicted IIEF-5 ⩾17 (AUC = 0.71, p = 0.004) with 46.2% sensitivity and 95.2% specificity. Mean pulsatility index ⩽1.41 predicted IIEF-5 ⩾17 (AUC = 0.75, p = 0.0005) with 48.5% sensitivity and 95.14% specificity. CONCLUSIONS: TR-CDU proved to be a feasible and non-invasive procedure, easily repeatable and not time consuming, overcoming the limits of PDDU-ICI. Diagnostic accuracy seems to be promising in discriminating patients with normal erectile function or mild dysfunction from those with moderate to severe ED. However, these findings need to be verified in future controlled randomized clinical trials.
