Abstract
BACKGROUND Hepatic fibrosis and secondary biliary cirrhosis are consequences of long-standing benign biliary strictures. Evidence on the reversibility of fibrosis after the repair is incongruous. METHODOLOGY A prospective observational study on patients who underwent Roux-en-Y hepaticojejunostomy for benign biliary stricture. A liver biopsy was performed during repair and correlated with preoperative elastography. The improvement in liver functions and regression of fibrosis was compared with preoperative liver function tests and elastography. RESULTS A Total of 47 patients [mean age-38.9 y (Range: 21 to 66)] with iatrogenic benign biliary stricture were included. A strong female preponderance was noted. High strictures (type III and IV) comprised 72.7% of the study group. The median interval (injury to repair) was 7 months (2 to 72 mo). The median duration of jaundice was 3 months (1 to 20 mo). Both factors had a significant correlation with the stage of fibrosis ( P =0.001 and P =0.03, respectively). Liver biopsy revealed stage I, II, III, and IV fibrosis in 26 (55.3%), 11 (23.4%), 2 (4.3%), and 2(4.3%), respectively. The remaining 6 (12.8%) had no fibrosis. The severity of fibrosis had a good correlation with preoperative liver stiffness measurement-value on FibroScan. Significant improvement in liver function tests (bilirubin-3.55±3.48 vs. 0.59±0.52; Albumin-3.85±0.61 vs. 4.14±0.37; ALP-507.66±300.65 vs. 167±132.07; P value 0.00) and regression of fibrosis (liver stiffness measurement; 10.42±5.91 vs. 5.85±3.01, P value 0.00) was observed after repair of the strictures. CONCLUSION Improved biliary function and regression of liver fibrosis can be achieved with timely repair of benign biliary stricture and it is feasible to be evaluated using elastography.

Abstract
There is evidence to suggest that M-type phospholipase A2 (PLA2R) antibodies activate the mannose-binding lectin (MBL) cascade, resulting in glomerular damage and proteinuria in patients with primary membranous nephropathy (PMN). Furthermore, there are few reports indicating that aberrant MBL activation is associated with endothelial dysfunction and accelerated atherosclerosis. While PMN is a common cause of adult nephrotic syndrome, and patients are at increased risk of cardiovascular disease (CVD), there is a lack of research that explores the factors that contribute to this condition. This study aims to determine the MBL levels in PMN and their relation to the clinical activity and endothelial dysfunction in PMN. The MBL levels of 22 biopsy-confirmed PMN patients were assessed at baseline and after 6 months of immunosuppressive therapy. In order to evaluate endothelial dysfunction in PMN patients, flow-mediated vasodilation (FMD) was measured at baseline and after treatment. A total of 22 healthy controls were included in this study to measure MBL levels and FMD. A significant difference was observed between MBL levels in PMN patients and healthy controls (p < .01). MBL levels decreased significantly after immunosuppressive therapy (p = .04). The baseline MBL levels and FMD levels exhibited a strong correlation (Spearman correlation coefficient [ρ] = 0.51: p = .01). In conclusion, the study signals the activation of the MBL cascade and its association with endothelial dysfunction in PMN patients.

Abstract
PURPOSE Prostate-specific membrane antigen (PSMA), in addition to its utility in prostate cancer, is also an angiogenic imaging marker for hypervascular tumors like renal cell carcinoma (RCC). Our study aims to assess the potential role of 68Ga-PSMA-11 positron emission tomography (PET)/CT in metastatic RCC and compare it with contrast-enhanced computed tomography (CECT). METHODS Biopsy-proven RCC patients with known or suspected distant metastases who underwent 68Ga-PSMA-11 PET/CT for staging/restaging were prospectively recruited. Those patients who had undergone 18F-FDG PET/CT within six weeks of 68Ga-PSMA PET/CT were also included retrospectively for comparative analysis. A patient-based and lesion-based analysis was done to compare the lesion detection rates of CECT, 68Ga-PSMA-11 PET and 18F-FDG PET. PET-based quantitative parameters were also compared between both the PET modalities. Impact of baseline parameters on survival was assessed using Cox regression analysis. A p-value of < 0.05 was considered significant. RESULTS Thirty-seven patients with median age 60 years ± 13 years (range = 26-76 years) were included in the study. Twenty-seven patients had clear cell (cc) RCC, six had papillary RCC (pRCC), and one each had an eosinophilic variant of ccRCC, collecting duct RCC, translocation RCC and poorly differentiated RCC. 68Ga-PSMA-11 PET performed better in detecting marrow and equivocal bone lesions and worse in detecting liver lesions compared to CECT. 68Ga-PSMA-11 PET-based angiogenic tumor burden estimation using Total Lesion-PSMA (TL-PSMA) and PSMA-Total volume (PSMA-TV) had a prognostic impact on the survival of patients. 68Ga-PSMA-11 PET also detected more lesions and showed significantly higher SUVmax than 18F-FDG PET. CONCLUSION 68Ga-PSMA-11 PET/CT performs better than CECT and 18F-FDG PET/CT in metastatic evaluation and has prognostic value in the management of clear cell RCC.

Abstract
Uterine artery embolization (UAE) is a technique for management of various obstetrical and gynecological problems. Transfemoral approach (TFA) is preferred which can be unilateral or bilateral; however, unilateral puncture is preferred due to lesser chances of puncture-related complications as compared to bilateral puncture. UAE through unilateral TFA is possible with use of reverse loop catheters (Roberts uterine catheter [RUC] or Gandras catheter) to access ipsilateral uterine artery. Other way of cannulating the ipsilateral uterine artery is by maneuvering catheters to form Waltman's loop/Simmon's reverse loop. With advent of RUC, unilateral TFA became standard of care. In the recent past, RUC was retracted from Indian market and its nonavailability had mandated use of either bilateral TFA or use of catheters and techniques used in the past for unilateral TFA. Herein, we describe a technique of doing UAE by unilateral TFA using simple gentle curve catheter (Picard) by making a reverse curve loop.

Abstract
Objective In this study, we compare the diagnostic accuracy of dual-energy (DE) computed tomography pulmonary angiography (CTPA) derived contrast enhancement (DECTPA, CTPA images with iodine maps) with standard dual-energy pulmonary angiography (SCTPA) for diagnosis of subsegmental pulmonary embolism in the cases with clinical suspicion of acute pulmonary embolism (APE). Materials and Methods We included 50 cases with clinical suspicion of APE that were referred for CTPA. All the patients underwent CTPA in the dual-energy protocol. Two radiologists evaluated the images. The first radiologist interpreted the SCTPA images (vascular images) and the second radiologist interpreted the DECTPA (CTPA images with iodine maps) for findings of APE. We calculated the sensitivity, specificity, and negative predictive value of DECTPA vis-à-vis SCTPA images. Results The DECTPA with the advantage of iodine map utilization yielded higher detection of thrombi in peripheral subsegmental arteries (72 vs. 99; p = - 0.001) as compared to the SCTPA images by identification of 18 new perfusion defects (interquartile range [IQR]: 0-1) that were consistent with APE. Filling defects were identified in 27 (IQR: 0-4) more subsegmental arteries supplying these 18 areas, which were not detected on SCTPA alone. These 18 perfusion defects were identified in 13 cases. In these 13 cases, 4 new cases were diagnosed that were negative on CTPA ( p = -0.125). In the evaluation of the APE, sensitivity and specificity were calculated and it was found that DECTPA showed 100% sensitivity and 86% specificity with 100% negative predictive value in the detection of thrombi as compared to the routine CTPA. Conclusion DECTPA has higher sensitivity and negative predictive value in the detection of the subsegmental perfusion defect identification as compared to SCTPA.

Abstract
AIMS Advanced gallbladder carcinoma (AGBC) carries a poor prognosis with dismal survival. There are no data regarding HER2/ERBB2 expression in AGBC. This study evaluated the overexpression of HER2/ERBB2 in cytological aspirates from AGBCs to identify potential patients for whom anti-HER2 targeted therapies can benefit. METHODS This prospective, case-control study was performed on 50 primary AGBC cases. A detailed cytomorphological assessment, followed by immunocytochemistry (ICC) for HER2/ERBB2, was performed on AGBC cell blocks. A similar number of age-matched and gender-matched resected chronic cholecystitis specimens were included as controls. Fluorescence in situ hybridisation (FISH) was performed in equivocal cases. RESULTS A total of 10 (20%) cases showed positive (3+), 19 (38%) equivocal (2+) expression and 21 (42%) were negative on HER2/ERBB2 ICC. None of the equivocal cases demonstrated HER2 amplification by FISH. Among the controls, none showed positive (3+) immunoexpression, 23 (46%) demonstrated equivocal expression and 27 (54%) were negative. On statistical analysis, HER2/ERBB2 overexpression was significantly associated with AGBC compared with the controls. Of all the clinical, radiological and cytomorphological parameters, the predominant papillary or acinar arrangements of the tumour cells were significantly associated with HER2/ERBB2 overexpression. CONCLUSIONS This is the first study to evaluate the expression of HER2/ERBB2 on cytological aspirates in AGBC using ICC and FISH. HER2/ERBB2 overexpression(20%) was significantly associated with AGBC. Furthermore, predominant papillary or acinar arrangements of tumour cells in the cytological smears were significantly associated with HER2/ERBB2 overexpression. They can serve as potential predictors of HER2/ERBB2 overexpression to select AGBC patients for anti-HER2 targeted therapies.

Abstract
Background An anomalous right coronary artery (ARCA) arising from the left sinus of Valsalva is an uncommon congenital anomaly. The unusual location, take-off and intramural courses of ARCA pose a considerable technical challenge during percutaneous coronary intervention (PCI). Aims We sought to report our experience of PCI of ARCA in 35 cases of atherosclerotic occlusion. Methods The PCI database of 35 cases of ARCA was retrospectively analysed. The details about demography, clinical presentation, PCI procedure and clinical follow-up were noted. Results The mean age was 56.7±13.5 years. The clinical presentation included stable angina in 45.7%, unstable angina in 20% and acute myocardial infarction in 34.3% of patients. Vascular access was transradial in 37.1% of cases, transfemoral in 60% of cases, and transbrachial in 1 case (2.9%). Judkins left and Amplatz left were commonly used guide catheters. Two patients with balloon-uncrossable, calcified lesions required rotablation-assisted PCI. Intravascular imaging was performed in 12 patients (34.3%). Optical coherence tomography demonstrated a proximal intramural course in 3 patients, and a slit-like orifice in 4 patients. The mean radiation dose and fluoroscopy time were 877±687.3 mGy and 18.8±11.6 minutes, respectively. Twenty-eight (80%) patients had an asymptomatic median follow-up of 49 (interquartile range: 29.0-97.5) months. Conclusions We performed successful PCI in a cohort of 35 patients with ARCA, with favourable long-term clinical outcomes. The selection of an appropriate guide catheter and technical skills were important factors in achieving favourable results.

Abstract
AbstractRenal cell carcinomas accounts for 2% of all the cancers globally. Most of the renal tumors are detected incidentally. Ultrasound remains the main screening modality to evaluate the renal masses. A multi -phase contrast enhanced computer tomography is must for characterizing the renal lesions. Imaging plays an important role in staging, treatment planning and follow up of renal cancers. In this review , we discuss the imaging guidelines for the management of renal tumors.

Abstract
A 45-year-old man presented with pain in the abdomen and pulsatile abdominal swelling of 3-month duration. He had kidney transplantation for chronic kidney disease 2 years prior. After discovering a fusiform abdominal aortic aneurysm, extending from the origin of the superior mesenteric artery to the aortic bifurcation, a hybrid aortic intervention was planned. In this case, we demonstrate a favorable long-term outcome of endovascular aortic repair for juxtarenal abdominal aortic aneurysm in a post-renal transplant patient.

Abstract
UNLABELLED This study identified the costs and health-related quality of life impacts of several post-fracture multidisciplinary care pathways specific to individual skeletal site (hip, distal forearm, vertebrae, humerus). These care pathways may assist healthcare providers in allocating resources for osteoporotic fractures in more effective and cost-efficient ways. INTRODUCTION This micro-costing study was undertaken to provide the estimated healthcare costs of several fracture site-specific health service use pathways associated with different trajectories of health-related quality of life (HRQoL) 12-months post-fracture. METHODS The study included 4126 adults aged ≥ 50 years with a fragility fracture (1657 hip, 681 vertebrae, 1354 distal forearm, 434 humerus) from the International Costs & Utilities Related to Osteoporotic fractures Study (ICUROS). ICUROS participants were asked to recall the frequency and duration (where applicable) of their health and community care service use at 4- and 12-month follow-up visits. Patient-level costs were identified and aggregated to determine the average cost of healthcare use related to the fracture in each care pathway (presented in Australian 2021 dollars). Mean cost differences were calculated and analysed using a one-way analysis of variance (ANOVA) and post hoc Bonferroni correction to determine any statistically significant differences. RESULTS The total direct cost of fractures was estimated at $89564, $38926, $18333, and $38461AUD per patient for hip, vertebral, wrist, and humeral participants, respectively. A Kruskal-Wallis test yielded a statistically significant difference in cost values between most care pathways (p < 0.001). Of the 20 care pathways, those associated with recovery of HRQoL had lower mean costs per patient across each fracture site. CONCLUSIONS This study identified the costs and HRQoL impacts of several multidisciplinary care pathways for individual fracture sites based on the health service utilization of an international cohort of older adults. These care pathways may assist healthcare providers in allocating resources for fragility fractures in more effective and cost-efficient ways.

Abstract
AbstractNeuroendocrine tumors (NET) of the biliary system, specifically the gallbladder (GB), are extremely rare, accounting for only 0.2% of all NETs. The majority of GBNETs are discovered by chance during a histological examination of GB samples at autopsy, after cholecystectomy, or after surgery for other suspected biliary pathology. GBNETs are thought to develop from preexisting endocrine cells in the GB's neck or from induced endocrine cells caused by intestinal metaplasia of the body and fundus. We present a case of squamous cell carcinoma of the GB with neuroendocrine differentiation due to its rarity.

Abstract
AIM To compare the diagnostic performance of contrast enhanced ultrasound (CEUS) and multiphasic contrast enhanced computed tomography (CECT) in differentiating benign and malignant gallbladder (GB) lesions. METHODS This prospective ethical review board approved study comprised consecutive patients with GB lesions who underwent CEUS and multiphasic CECT at a tertiary care referral center. The enhancement patterns at CEUS and CT were compared. The quantitative CEUS parameters including arrival time (AT), AT in liver, time to peak enhancement, and washout time (WT) were assessed. The diagnostic performance of CEUS and CT features was calculated using receiver operating characteristic analysis. A subgroup analysis was performed for patients with GB wall thickening. Multivariate analysis was performed to identify features significantly associated with malignancy. RESULTS Over the study period, 30 patients (mean age, 52.8 ± 12.2 years, 17 females) with GB lesions were evaluated. Benign and malignant diseases were present in 13 and 17 patients, respectively. There was excellent agreement between CEUS and CT findings. Among the quantitative CEUS features, only WT was significantly associated with malignancy in the overall group (p < 0.001) and wall thickening subgroup (p = 0.007). WT within 53.5 s and 51.5 s had sensitivity of 88.2% and 81.8% and specificity of 84.5% and 100% in diagnosing malignant lesions in the overall group (AUC 0.900) and the wall thickening subgroup (area under curve, AUC 0.927), respectively. At multivariate analysis, features that were significantly associated with malignant lesions in the overall group were disruption of GB wall (CEUS), intralesional non-enhancing areas (CEUS), liver involvement (CEUS or CT), and arterial phase hyperenhancement (CT) in the overall group and disruption of GB wall (CEUS), WT (CEUS), and liver involvement (CEUS or CT) in the wall thickening subgroup. CONCLUSION CEUS is a useful adjunct to CT in evaluation of GB lesions. Its utilization in patients with GB wall thickening may improve detection of malignancy.

Abstract
Renal transplant remains the preferred therapy for end-stage renal disease (ESRD). Given the shortage of suitable donor kidneys, use of an expanded criteria donor (ECD) allows marginal kidneys to be transplanted; albeit at risk of increased graft failure due to lower nephron mass. To reduce the risk of graft failure, double kidney transplant (DKT) is advocated, with favorable outcomes. Transplant renal artery stenosis (TRAS) is one of the most common vascular complications following renal transplant. Unlike single kidney transplants, where TRAS usually presents with fluid overload, uncontrolled hypertension, and worsening kidney functions; it may be clinically silent in DKT patients since they have two functional transplanted kidneys. We hereby report a case of TRAS in a DKT patient who had 2 years of favorable clinical outcomes following successful endovascular stenting. He however recently died of COVID-19 associated pneumonitis.

Abstract
We report on the development of multi-beam radio frequency (RF) linear ion accelerators that are formed from stacks of low cost wafers and describe the status of beam power scale-up using an array of 112 beams. The total argon ion current extracted from the 112-beamlet extraction column was 0.5 mA. The measured energy gain in each RF gap reached as high as 7.25 keV. We present a path toward using this technology to achieve ion currents >1 mA and ion energies >100 keV for applications in material processing.

Abstract
Lymphatic malformations are congenital vascular malformations with lymphatic differentiation. Although the most common locations for lymphatic malformation are the neck and axilla, they can occur at several locations in the body including the abdomen. The abdominal location is rather rare and accounts for approximately 5% of all lymphatic malformation. Abdominal lymphatic malformation can arise from mesentery, omentum, gastrointestinal tract, and retroperitoneum. Clinical presentation includes an abdominal lump, vague abdominal discomfort, and secondary complications including intestinal obstruction, volvulus, ischemia, and bleeding. There is a broad spectrum of radiological manifestation. In the present review, we discuss the imaging appearance of abdominal lymphatic malformation. The diagnosis of lymphatic malformation in our series was based on the histopathological examination (in cases who underwent surgery) and fine needle aspiration cytology.

Abstract
Objective Conservative approaches in muscle-invasive bladder cancer (MIBC) have been evolved to avoid aggressive surgery, but are limited to elderly, frail, and patients medically unfit for surgery. Our study aimed to assess the response rate of neoadjuvant chemotherapy (NACT) before radiotherapy (RT) in MIBC patients. Methods Forty patients with urothelial carcinoma of stage T2–T4a, N0, M0 were enrolled between November 2013 and November 2015, and treated with three cycles of NACT with gemcitabine-cisplatin. Post-NACT response was assessed using Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Patients who achieved complete response (CR) and partial response (PR) >50% were treated with radical RT, and those who had PR <50%, stable disease (SD), and progressive disease (PD) underwent radical cystectomy (RC). Survival analysis was done with Kaplan-Meier method and point-to-time events were analyzed with Cox-proportional hazards regression model. Results After NACT, 35 (87.5%) patients achieved either PR >50% or CR, and were treated with RT. Five (12.5%) patients who had PR <50%, SD, or PD underwent RC. All patients who received radiation showed CR after 6 weeks. Median follow-up was 43 months (range: 10–66 months) and median overall survival (OS) was not reached. Three-year OS, local control, and disease-free survival were 70.1%, 60.9%, 50.6%, respectively, and 50% of patients preserved their functioning bladder. Three-year OS rate was 88.9% in patients who achieved CR to NACT, 73.1% in patients with PR ≥50% and 40% in patients with PR <50%. Conclusion NACT followed by RT provides a high probability of local response with bladder preservation in CR patients. Appropriate use of this treatment regimen in carefully selected patients may omit the need for morbid surgery.

Abstract
Background and Aim Accurate anatomical delineation is the key before definitive repair for benign biliary stricture (BBS). The role of percutaneous transhepatic cholangiography (PTC) as a road map is less studied in the era of magnetic resonance cholangiopancreatography (MRCP). Methods A prospective observational study, performed between July 2012 and December 2013. All patients of post‐cholecystectomy BBS were evaluated with MRCP and PTC prior to definitive repair. Findings of MRCP and PTC were compared with intraoperative details. Results Thirty patients with BBS were included in the study. MRCP was performed in all but PTC was amenable in 28 of 30 (93.3%) patients. PTC was comparable to MRCP in diagnosing stricture type (96.4% vs 89.3%), intrahepatic stones (75% vs 75%), and biliary anomalies (95.6% vs 100%). Additionally, PTC revealed internal biliary fistula in 4 (85.7% vs 61.4%; P value 0.04). PTC‐related minor complications were noted in 2 (7.1%) patients. Conclusion PTC is comparable to MRCP in diagnosing the stricture type, intrahepatic biliary stones, and biliary anomalies. Though comparable to MRCP, the authors could not reveal any additional information that could change the course of management in BBS.

Abstract
Coronary artery disease is one of the leading causes of mortality in the world. The presence of concomitant peripheral artery disease increases the risks of cardiovascular events along with limiting the arterial access for coronary intervention. Invasive management of such cases includes either alternate site access or combined peripheral and coronary revascularization. We hereby report a patient of the infrarenal abdominal aorta and bilateral subclavian arterial occlusion, who presented with acute coronary syndrome. To perform the percutaneous coronary intervention, we first performed the endovascular stenting of occluded aortoiliac disease, followed by stenting of the right coronary artery. We had discussed the limitation of arterial access to perform PCI in such a situation.

Abstract
INTRODUCTION The present study was undertaken to assess the accuracy of fine needle aspiration cytology (FNAC) and cell-block immunocytochemistry, and to estimate the risk of malignancy, using a categorical reporting system, in the diagnosis of ovarian masses. METHODS This was a 5-year retrospective study of FNAs of ovarian masses. The cytological diagnoses were categorised as inadequate, non-neoplastic, benign neoplasms, indeterminate for malignancy, suspicious for malignancy and malignant neoplasms. The cytology was correlated with the corresponding histopathology to assess the diagnostic accuracy and risk of malignancy associated with each diagnostic category. RESULTS Of a total of 66 703 FNAs performed during the study period, 580 (0.9%) were performed on ovarian masses. Of these, 40 (6.9%) were reported as non-neoplastic; 76 (13.1%) as benign neoplasms; 14 (2.4%) as indeterminate for malignancy, 48 (8.3%) as suspicious for malignancy, 337 (58.1%) as malignant neoplasms and 65 (11.2%) as inadequate for interpretation. Immunocytochemistry (ICC) was performed on 99 (17%) aspirates. Subsequent histopathology was available in 208 (35.8%) cases. On cyto-histopathological correlation, 183 (88%) were concordant and 25 (12%) were discordant. The overall sensitivity, specificity, positive and negative predictive values and diagnostic accuracy for diagnosing ovarian malignancy were 88.4%, 85.7%, 96.8%, 60.0% and 88% respectively. Risk of malignancy for each category was 80%, 0%, 4.5%, 66.7%, 88.5% and 98.5% respectively. CONCLUSIONS Ultrasound-guided FNAC has high specificity and diagnostic accuracy for preoperative diagnosis of ovarian malignancies and hence is a valid diagnostic procedure in certain clinical situations. Reporting using a categorical system imparts uniformity and also provides the clinicians with an associated risk of malignancy to guide further management.

Abstract
Anastomotic site pseudoaneurysm following renal transplantation is a rare vascular complication. Its etiology include defective suture techniques and infections. The clinical presentation includes allograft dysfunction, local mass effect, exsanguination, and rupture. Open surgical repair is associated with significant morbidity and allograft dysfunction. Endovascular stent-graft can be a less invasive, alternative approach. We describe a case of large pseudoaneurysm arising from the internal iliac artery in a post-renal transplant patient. It was successfully treated with the stent-graft. The externally compressed right common iliac vein was also treated with a self-expanding non-graft stent. Thus, endovascular approach can be an effective alternative to open repair for post-renal transplant iliac artery pseudoaneurysm.

Abstract
BACKGROUND Transplant renal artery stenosis (TRAS) is an uncommon complication following renal transplantation. Its usual clinical presentation includes worsening hypertension and/or renal function, without any evidence of graft rejection. Bifurcation renal artery stenosis of the transplanted renal artery is rarely encountered. METHODS Percutaneous transluminal renal angioplasty (PTRA) with or without stenting is the procedure of choice to treat TRAS. We hereby describe a patient, who presented with impaired renal functions, four months following the renal transplantation. He underwent intravascular ultrasound-guided PTRA of the bifurcation lesion of TRAS.Results and conclusion: Superior renal artery had coronary drug-eluting stent implantation, while inferior renal artery and side branch of the superior renal artery had balloon angioplasty, alone. Post-intervention, the raised serum creatinine level decreased from 2.9 mg% to 1.7 mg%. The index case described the successful PTRA and stenting of the bifurcation lesion of TRAS, the technical results of which was optimized with the use of intravascular ultrasound.

Abstract
Prostate cancer (PCa) is one of the major causes of death due to cancer in men. Conventional imaging modalities such as magnetic resonance imaging (MRI) provide locoregional status, but fall short in identifying distant metastasis. C-11 choline F-18 fluorocholine (F-18 FCH) has been shown to be useful in imaging of PCa. The present prospective study evaluates and compares the role of F-18 FCH positron emission tomography-computed tomography (PET-CT) with locoregional MRI and whole-body bone scintigraphy in PCa patients for initial staging and recurrence evaluation. This study included a total of 50 patients. Tc-99m skeletal scintigraphy, F-18 FCH PET-CT, and diffusion-weighted MRI of the pelvic region were performed within a span of 2-3 weeks of each other, in random order. For the primary site, core biopsy findings of the lesion were considered as gold standard. The kappa test was used to measure agreement between bone scintigraphy, F-18 FCH, and MRI. For comparing Tc-99m bone scintigraphy, F-18 FCH, and MRI, McNemar's test was applied. F-18 FCH PET-CT and MRI were able to detect primary lesion in all initial staging patients. The sensitivity and specificity of F-18 FCH PET-CT versus MRI were found to be 92.8% versus 89.2% and 100 versus 80%, respectively, for the recurrence at the primary site. A total of 55 bony lesions at distant sites were detected on F-18 FCH PET-CT in comparison to 43 bone lesions on whole-body bone scintigraphy. F-18 FCH PET/CT also detected additional lung lesions in 2 patients and abdominal lymph nodes in 12 patients. F-18 FCH PET-CT could detect primary lesions, local metastasis, bone metastasis, and distant metastasis in a single study and is also a useful modality in recurrence evaluation in PCa patients.

Abstract
Various vascular complications following renal transplantation include renal artery and vein thrombosis, renal artery stenosis, pseudoaneurysm, and iliac artery dissection. Transplant renal artery stenosis (TRAS) is the most common, while iliac artery dissection is the rarest of these various vascular complications. We describe an elderly male, who had both external iliac artery dissection and TRAS at 2 months following renal transplantation. He underwent successful percutaneous endovascular intervention of both complications. The post-intervention course was uneventful, with improvement in graft renal functions and left lower limb perfusion.

Abstract
Background Retroperitoneal open iliac conduits (ROIC) are used in patients with hostile iliac anatomy undergoing endovascular aortic repair (EVAR). Objectives We hereby report our experience of ROIC in patients subjected to EVAR. Methods This was a retrospective evaluation of 8 patients out of a total of 75 patients (11%) who underwent EVAR in the last 10 years. Pre-procedure computed tomography angiography was used to assess the dimensions of iliac and femoral arteries. Patients who had small arterial dimensions (i.e. smaller than the recommended access size for the aortic endograft device) were subjected to ROIC. Results The mean age of the 3 males and 5 females studied was 45.7 ± 15.2 years. The indication for ROIC was the small caliber ilio-femoral access site in 7 patients and atherosclerotic disease in 1 patient. All external grafts were anastomosed to the right common iliac artery except one which was anastomosed to the aortic bifurcation site because of a small common iliac artery. The procedural success rate was 100%. Local access site complications included infection (n=1), retroperitoneal hematoma (n=1), and need for blood transfusion (n=3). The median post-intervention hospital stay was 10 days. All patients had favorable long-term outcomes at a median follow-up of 18 months. Conclusions Female patients require ROIC during EVAR more frequently. Adjunctive use of iliac conduit for EVAR was associated with favorable perioperative and short-term outcomes.

Abstract
Background Aorto-oesophageal fistula (AOF) is a rare, catastrophic disease with an extremely poor prognosis. A ruptured thoracic aortic aneurysm is a common aetiology for AOF. The clinical presentation is usually massive haematemesis and collapse. Timely diagnosis and appropriate treatment are crucial in managing AOF. Case summary We hereby report two cases of AOF, who underwent successful emergency thoracic endovascular aortic repair (TEVAR) to control active bleed and exsanguination. Case 1, an elderly lady with atherosclerotic aneurysm had TEVAR followed by open surgery for oesophageal rent and necrosed left main bronchus. Case 2 had mycotic tubercular aneurysm who later had infected graft-stent following TEVAR. Discussion Open surgery is the conventional treatment for AOF; however, TEVAR can be an alternative and less invasive approach in selected high-risk patients. Various management issues related to TEVAR with AOF have been discussed in the article.

Abstract
Background Aortobronchial fistula (ABF) formation following the rupture of thoracic pseudoaneurysm is a rare clinical entity. Its aetiology includes atherosclerosis, infections, trauma, post-surgery, and post-endovascular aortic repair. The clinical presentation of ABF includes intermittent or massive haemoptysis, acute respiratory distress, hypotension, and even death. These patients require an emergency aortic intervention to stop active haemorrhage. Thoracic endovascular aortic repair (TEVAR) is a less invasive, safe, and effective treatment compared to conventional open surgical repair Case summary We hereby report three cases of ruptured descending thoracic aortic pseudoaneurysms resulting in a fistula formation. The first two cases had tuberculosis as their underlying aetiology, while the third case was the result of previous open post-aortic surgery. All patients presented with massive haemoptysis and were successfully treated by emergency TEVAR and had favourable outcomes. Discussion Thoracic endovascular aortic repair is a rapid, less invasive, and effective treatment for emergency management of ABF. It has more than 85% technical success rates in the reported literature. We had procedural success in all three cases. The short and midterm outcome of ABF following TEVAR is favourable and encouraging.

Abstract
Objectives Renal pseudoaneurysms are multifactorial in origin, and angioembolization remains the mainstay of treatment. Few case reports have also described percutaneous embolization using glue or thrombin. Our study aimed to evaluate the predictors of active bleed by analyzing their etiology, morphology, imaging features, and treatment adopted. To the best of our knowledge, this is the largest such study done in India.
Methods This was a retrospective study of patients treated for renal pseudoaneurysms between 2014 and 2019. We reviewed their clinical data, treatment modalities used, and clinical outcomes. We also assessed computed tomography angiography (CTA) and conventional angiography images.
Results A total of 79 patients (54 males and 25 females) were included in the study. The mean age was 39.5 years (range 15–83 years). The most common cause was renal biopsy, followed by surgery. Of these, three patients (3.9%) had more than one lesion and 57% of pseudoaneurysms were seen in lower polar arteries. Active contrast extravasation was seen in 15.2% (n = 12) of the patients and 21.5% (n = 17) showed lobulations in CT and digital substraction angiography. The mean size of the pseudoaneurysms was 1.17 cm (SD 0.7); 22.8% of pseudoaneurysms were wide necked. The embolization was approached by endovascular (89.9%), percutaneous (10.1%), or both (1.3%) routes. Embolization was performed using microcoils (78.5%), gel foam (12.7%), N-butyl cyanoacrylate glue (8.9%), polyvinyl alcohol (8.9%), and thrombin (5.1%) either as a single agent or in combination. The technical success was achieved in all cases after the first procedure. Pseudoaneurysms with a wide neck (p = 0.03) and lobulations (p = 0.002) were associated with active contrast extravasation. Episodes of rebleeding were seen at a younger age (p-value = 0.02).
Conclusion Minimally invasive methods remain the cornerstone in the management of renal pseudoaneurysms with high success rates. The morphology of pseudoaneurysms can help predict the risk of active bleeding and decide the type of intervention. Direct percutaneous injection into the aneurysm sac is an alternate technique and should be considered when an endovascular approach is challenging.

Abstract
A 42-year-old female with end-stage chronic kidney disease, who was on maintenance hemodialysis for the last 3 years, presented with facial and upper-limb swelling of 2-month duration. A computed tomography (CT) scan confirmed significant stenosis of the superior vena cava (SVC). Following discussion in a multidisciplinary meeting, it was proposed to perform a repeat endovascular intervention to relieve the SVC obstruction and manage the migrated stent.

Abstract
The Absorb bioresorbable vascular scaffold (Abbott Vascular) does not have an artifact on computed tomography coronary angiography (CTCA); the extent/location of the stent in situ can only be assessed by localizing its radiopaque platinum markers in a non-contrast CTCA. The characteristic appearance of BVS on CTCA should be interpreted as the footprint of a resorbed BVS, instead of a calcified plaque.

Abstract
Aims The aims of this study were to: identify current practice regarding low molecular weight heparin (LMWH) prophylaxis in elective breast surgery, to determine if timing of administration of LMWH prophylaxis or specific patient demographic factors impacts the rate of post-operative haematoma formation. Methods Retrospective cohort study involving 100 patients who underwent elective breast surgery in a tertiary centre in Ireland in 2017. Medical charts were reviewed to collect data on; timing of LMWH administration, incidence of post-operative haematoma and patient's age, BMI, smoking status and anti-coagulant use. Statistical analysis was then performed. Results Forty-two patients (42%) received enoxaparin pre-operatively and thirty-one patients (31%) post-operatively. Incidence of post-operative haematoma was 4% (n=4). Of the haematoma group, three patients (75%) received post-operative enoxaparin (p=0.166). Independent patient factors did not significantly impact rate of haematoma formation. Conclusions Post-operative haematoma rate is 4%. Timing of LMWH prophylaxis administration did not significantly affect this rate.
