| 1 | Imaging and interventions in hilar cholangiocarcinoma: A review显示文摘Hilar cholangiocarcinoma is a common malignant tumor of the biliary tree. It has poor prognosis with very low 5-year survival rates. Various imaging modalities are available for detection and staging of the hilar cholangiocarcinoma. Although ultrasonography is the initial investigation of choice, imaging with contrast enhanced computed tomography scan or magnetic resonance imaging is needed prior to management. Surgery is curative wherever possible. Radiological interventions play a role in operable patients in theform of biliary drainage and/or portal vein embolization. In inoperable cases, palliative interventions include biliary drainage, biliary stenting and intra-biliary palliative treatment techniques. Complete knowledge of application of various imaging modalities available and about the possible radiological interventions is important for a radiologist to play a critical role in appropriate management of such patients.We review the various imaging techniques and appearances of hilar cholangiocarcinoma and the possible radiological interventions. | Kumble Seetharama Madhusudhan Shivanand Gamanagatti Arun Kumar Gupta | 2015 | World Journal of Radiology2015，7，2： | 18 |
| 2 | Imaging evaluation of traumatic thoracolumbar spine injuries: Radiological review显示文摘Spine fractures account for a large portion of musculoskeletal injuries worldwide. A classification of spine fractures is necessary in order to develop a common language for treatment indications and outcomes. Several classification systems have been developed based on injury anatomy or mechanisms of action, but they have demonstrated poor reliability, have yielded little prognostic information, and have not been widely used. For this reason, the Arbeitsgemeinschaftfür Osteosynthesefragen(AO) committee has classified thorocolumbar spine injuries based on the pathomorphological criteria into3 types(A: Compression; B: Distraction; C: Axial torque and rotational deformity). Each of these types is further divided into 3 groups and 3 subgroups reflecting progressive scale of morphological damage and the degree of instability. Because of its highly detailed sub classifications, the AO system has shown limited interobserver variability. It is similar to its predecessors in that it does not incorporate the patient's neurologic status.The need for a reliable, reproducible, clinically relevant, prognostic classification system with an optimal balance of ease of use and detail of injury description contributed to the development of a new classification system, the thoracolumbar injury classification and severity score(TLICS). The TLICS defines injury based on three clinical characteristics: injury morphology, integrity of the posterior ligamentous complex, and neurologic status of the patient. The severity score offers prognostic information and is helpful in decision making about surgical vs nonsurgical management. | Shivanand Gamanagatti Deepak Rathinam Krithika Rangarajan Atin Kumar Kamran Farooque Vijay Sharma | 2015 | World Journal of Radiology2015，7，9： | 18 |
| 3 | Imaging and interventions in Budd-Chiari syndrome显示文摘Budd-Chiari syndrome(BCS) consists of a group of disorders with obstruction of hepatic venous outflow leading to increased hepatic sinusoidal pressure and portal hypertension.Clinically,two forms of disease(acute and chronic) are recognized.Mostly the patients present with ascites,hepatomegaly,and portal hypertension.In acute disease the liver is enlarged with thrombosed hepatic veins(HV) and ascites,whereas in the chronic form of the disease there may be membranous occlusion of HV and/or the inferior vena cava(IVC),or there may be short or long segment fibrotic constriction of HV or the suprahepatic IVC.Due to advances in radiological interventional techniques and hardware,there have been changes in the management protocol of BCS with surgery being offered to patients not suitable for radiological interventions or having acute liver failure requiring liver transplantation.The present article gives an insight into various imaging findings and interventional techniques employed in the management of BCS. | Amar Mukund Shivanand Gamanagatti | 2011 | World Journal of Radiology2011，3，7： | 11 |
| 4 | Blunt pancreatic trauma: A persistent diagnostic conundrum?显示文摘Blunt pancreatic trauma is an uncommon injury but has high morbidity and mortality. In modern era of trauma care, pancreatic trauma remains a persistent challenge to radiologists and surgeons alike. Early detection of pancreatic trauma is essential to prevent subsequent complications. However early pancreatic injury is often subtle on computed tomography(CT) and can be missed unless specifically looked for. Signs of pancreatic injury on CT include laceration, transection, bulky pancreas, heterogeneous enhancement, peripancreatic fluid and signs of pancreatitis. Pan-creatic ductal injury is a vital decision-making parameter as ductal injury is an indication for laparotomy. While lacerations involving more than half of pancreatic parenchyma are suggestive of ductal injury on CT, ductal injuries can be directly assessed on magnetic resonance imaging(MRI) or encoscopic retrograde cholangio-pancreatography. Pancreatic trauma also shows temporal evolution with increase in extent of injury with time. Hence early CT scans may underestimate the extent of injures and sequential imaging with CT or MRI is important in pancreatic trauma. Sequential imaging is also needed for successful nonoperative management of pancreatic injury. Accurate early detection on initial CT and adopting a multimodality and sequential imaging strategy can improve outcome in pancreatic trauma. | Atin Kumar Ananya Panda Shivanand Gamanagatti | 2016 | World Journal of Radiology2016，8，2： | 8 |
| 5 | Magnetic resonance imaging in glenohumeral instability显示文摘The glenohumeral joint is the most commonly dislocated joint of the body and anterior instability is the most common type of shoulder instability.Magnetic resonance (MR) imaging,and more recently,MR arthrography,have become the essential investigation modalities of glenohumeral instability,especially for pre-procedure evaluation before arthroscopic surgery.Injuries associated with glenohumeral instability are variable,and can involve the bones,the labor-ligamentous components,or the rotator cuff.Anterior instability is associated with injuries of the anterior labrum and the anterior band of the inferior glenohumeral ligament,in the form of Bankart lesion and its variants;whereas posterior instability is associated with reverse Bankart and reverse Hill-Sachs lesion.Multidirectional instability often has no labral pathology on imaging but shows specific osseous changes such as increased chondrolabral retroversion.This article reviews the relevant anatomy in brief,the MR imaging technique and the arthrographic technique,and describes the MR findings in each type of instability as well as common imaging pitfalls. | Manisha Jana Shivanand Gamanagatti | 2011 | World Journal of Radiology2011，3，9： | 7 |
| 6 | Endoscopic ultrasound guided thrombin injection of angiographically occult pancreatitis associated visceral artery pseudoaneurysms:Case series显示文摘Pseudoaneurysm is a known complication of pancreatitis associated with significant mortality and morbidity. Imaging plays an important role in the diagnosis and management. Computed tomography(CT) helps localize the lesion and the severity of the background pancreatitis but digital subtraction angiography with coil embolization is recommended to avoid bleeding and inadvertent surgery. However, in cases where angiographic coil embolization is not feasible due to technical reasons, thrombin injection via CT or ultrasound guidance remains a viable option and often described in literature. In this series, effort has been made to highlight the role of endoscopic ultrasound guided thrombin instillation especially in patients with poorly visualized pseudoaneurysm on ultrasound thereby avoiding surgery and the associated mortality and morbidity. | Shivanand Gamanagatti Usha Thingujam Pramod Garg Surajkumar Nongthombam Nihar Ranjan Dash | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，13： | 6 |
| 7 | Imaging in renal trauma显示文摘Renal injuries are classified,based on the American Association for the Surgery of Trauma classification,in to five grades of injury.Several imaging modalities have been available for assessing the grade of renal injury,each with their usefulness and limitations.Currently,plain radiographs and intravenous urography have no role in the evaluation of patients with suspected renal injury.Ultrasonography(USG) has a limited role in evaluating patients with suspected retroperitoneal injury;however,it plays an important role during follow up in patients with urinoma formation.USG helps to monitor the size of a urinoma and also for the drainage procedure.The role of selective renal arteriography is mainly limited to an interventional purpose rather than for diagnostic utility.Retrograde pyelography is useful in assessing ureteral and renal pelvis integrity in suspected ureteropelvic junction injury and for an interventional purpose,like placing a stent across the site of ureteric injury.Magnetic resonance imaging has no role in acute renal injuries.Multidetector computed tomography is the modality of choice in the evaluation of renal injuries.It is also useful in evaluating traumatic injuries to kidneys with preexisting abnormalities and can help to define the extent of penetrating injuries in patients with stab wounds in the flank region.The combination of imaging findings along with clinical information is important in the management of the individual patient.This article will describe a spectrum of renal injuries encountered in a trauma setting. | Madhukar Dayal Shivanand Gamanagatti Atin Kumar | 2013 | World Journal of Radiology2013，5，8： | 6 |
| 8 | Endovascular management in abdominal visceral arterial aneurysms:A pictorial essay显示文摘Visceral artery aneurysms(VAAs) include aneurysms of the splanchnic circulation and those of the renal artery.Their diagnosis is clinically important because of the associated high mortality and potential complications.Splenic,superior mesenteric,gastroduodenal,hepatic and renal arteries are some of the common arteries affected by VAAs.Though surgical resection and anastomosis still remains the treatment of choice in some of the cases,especially cases involving the proximal arteries,increasingly endovascular treatment is being used for more distal vessels.We present a pictorial review of various intra-abdominal VAAs and their endovascular management. | Manisha Jana Shivanand Gamanagatti Amar Mukund Sujoy Paul Pankaj Gupta Pramod Garg Tushar K Chattopadhyay Peush Sahni | 2011 | World Journal of Radiology2011，3，7： | 5 |
| 9 | Endoscopic retrograde cholangiopancreatography:Current practice and future research显示文摘Endoscopic retrograde cholangiopancreatography(ERCP)has evolved from a primarily diagnostic to therapeutic procedure in hepatobiliary and pancreatic disease.Most commonly,ERCPs are performed for choledocholithiasis with or without cholangitis,but improvements in technology and technique have allowed for management of pancreatic duct stones,benign and malignant strictures,and bile and pancreatic leaks.As an example of necessity driving innovation,the new disposable duodenoscopes have been introduced into practice.With the advantage of eliminating transmissible infections,they represent a paradigm shift in quality improvement within ERCP.With procedures becoming more complicated,the necessity for anesthesia involvement and safety of propofol use and general anesthesia has become better defined.The improvements in endoscopic ultrasound(EUS)have allowed for direct bile duct access and EUS facilitated bile duct access for ERCP.In patients with surgically altered anatomy,selective cannulation can be performed with overtube-assisted enteroscopy,laparoscopic surgery assistance,or the EUS-directed transgastric ERCP.Cholangioscopy and pancreatoscopy use has become ubiquitous with defined indications for large bile duct stones,indeterminate strictures,and hepatobiliary and pancreatic neoplasia.This review summarizes the recent advances in infection prevention,quality improvement,pancreaticobiliary access,and management of hepatobiliary and pancreatic diseases.Where appropriate,future research directions are included in each section. | David J Sanders Shivanand Bomman Rajesh Krishnamoorthi Richard A Kozarek | 2021 | World Journal of Gastrointestinal Endoscopy2021，13，8： | 5 |
| 10 | Preoperative transarterial Embolisation in bone tumors显示文摘Bone tumors include a variety of lesions, both primary and metastatic. The treatment modalities for bone tumors vary with the individual lesion, but in general surgical excision is the treatment of choice with other adjunctive therapies. However, surgery for many bone tumors is complex due to several factors including tumor bulk, vascularity, vicinity to vital structures and potentially inaccessible location of the lesion. Transarterial Embolisation (TAE) is one of the important adjuvant treatment modalities and in some cases it may be the primary and curative treatment. Preoperative TAE has proved to be effective in both primary and metastatic bone tumors. It reduces tumor vascularity and intraoperative blood loss, the need for blood transfusion and associated complications, allows better definition of tissue planes at surgery affording more complete excision, and hence reduced recurrence. Preoperative chemoEmbolisation has also been shown to increase the sensitivity of some tumors to subsequent chemotherapy and radiotherapy. There are several techniques and embolic agents available for this purpose, but the ultimate aim is to achieve tumor devascularization. In this review, we discuss the techniques including the choice of embolic agent, application to individual lesions and potential complications. | Pankaj Gupta Shivanand Gamanagatti | 2012 | World Journal of Radiology2012，4，5： | 3 |
| 11 | Bipolar radiofrequency ablation of tibialchondroblastomas: A report of three cases显示文摘Chondroblastoma is a rare benign cartilaginous neoplasm of bone. The recurrence rate is high and complications are frequent following open curettage with bone grafting which is the standard treatment forchondroblastomas. We performed radiofrequency ablation in three cases of tibialchondroblastoma using the bipolar system. One patient experienced residual pain for which repeat ablation was performed. No other complications were observed during follow-up. Radiofrequency ablation may offer an effective alternative for the treatment of selected cases of chondroblastoma. The lesion characteristics which are likely to influence treatment outcome and the advantages offered by the bipolar system are discussed. | Prathiba Rajalakshmi Deep N Srivastava Shivanand Gamanagatti Pramod Kumar Julka Sushma Bhatnagar Shishir Rastogi | 2012 | World Journal of Radiology2012，4，7： | 2 |
| 12 | Radiological interventions in malignant biliary obstruction显示文摘Malignant biliary obstruction is commonly caused by gall bladder carcinoma, cholangiocarcinoma and metastatic nodes. Percutaneous interventions play an important role in managing these patients. Biliary drainage, which forms the major bulk of radiological interventions, can be pal iative in inoperable patients or pre-operative to improve liver function prior to surgery. Other interventions include cholecystostomy and radiofrequency ablation. We present here the indications, contraindications, technique and complications of the radiological interventions performed in patients with malignant biliary obstruction. | Kumble Seetharama Madhusudhan Shivanand Gamanagatti Deep Narayan Srivastava Arun Kumar Gupta | 2016 | World Journal of Radiology2016，8，5： | 2 |

| 19 | Preoperative embolization of primary bone tumors:A case control study显示文摘AIM:To study the safety and effectiveness of preoperative embolization of primary bone tumors in relation to intraoperative blood loss,intraoperative blood transfusion volume and surgical time.METHODS:Thirty-three patients underwent preoperative embolization of primary tumors of extremities,hip or vertebrae before resection and stabilization.The primary osseous tumors included giant cell tumors,aneurysmal bone cyst,osteoblastoma,chondroblastoma and chondrosarcoma.Twenty-six patients were included for the statistical analysis(embolization group)as they were operated within 0-48 h within preoperative embolization.A control group(non-embolization group,n = 28)with bone tumor having similar histological diagnosis and operated without embolization was retrieved from hospital record for statistical comparison.RESULTS:The mean intraoperative blood loss was 1300 mL(250-2900 mL),the mean intraoperative blood transfusion was 700 m L(0-1400 m L)and the mean surgical time was 221 ± 76.7 min for embolization group(group Ⅰ,n = 26).Non-embolization group(group Ⅱ,n = 28),the mean intraoperative blood loss was 1800 m L(800-6000 m L),the mean intraoperative blood transfusion was 1400 mL(700-8400 mL)and the meansurgical time was 250 ± 69.7 min.On comparison,statistically significant(P < 0.001)difference was found between embolisation group and non-embolisation group for the amount of blood loss and requirement of blood transfusion.There was no statistical difference between the two groups for the surgical time.No patients developed any angiography or embolization related complications.CONCLUSION:Preoperative embolization of bone tumors is a safe and effective adjunct to the surgical management of primary bone tumors that leads to reduction in intraoperative blood loss and blood transfusion volume. | Roushan Jha Raju Sharma Shishir Rastogi Shah Alam Khan Arvind Jayaswal Shivanand Gamanagatti | 2016 | World Journal of Radiology2016，8，4： | 1 |
