He was an Assistant Professor of Radiology at Duke University Medical Center in North Carolina from 1998-2004.

Professor Ryan specialises in delivering minimally invasive oncological and endovascular treatments for many forms of cancer, portal hypertension, liver disease, and for bleeding and thrombotic disorders.

He has a particular interest in minimally invasive treatments for cancer including chemoembolization and ablation therapies. He has specialist clinical and research interest in the endovascular management of haemorrhage and thrombosis, and in performing treatments for the management of chronic urinary obstruction in the setting of gynaecological malignancy.

Professor Ryan has been actively involved in academics and clinical research for over 25 years, during which time he has published and presented more than 170 peer-reviewed scientific papers, editorials, articles, and book chapters with > 2700 citations in the medical literature (Google Scholar: h-index 27, i10 index 48).

Professor Ryan has lectured in Europe, Asia and the USA and has been on Faculty for international conferences for over two decades including The Society of Interventional Radiology (SIR), The International Symposium on Endovacular Therapies (ISET), The Cardiovascular Interventional Radiology Society of Europe (CIRSE),The European Congress of Radiology (ECR), Global Embolization Symposium and Technologies (GEST) and European (ECIO) and World Congresses of Interventional Oncology (WCIO).

He was a Member of the e-Learning Sub-Committee for Interventional Radiology for the European Society of Radiology (ESR) for 2020-2021.

He was a Faculty Member of CIRSE 2020, and a Scientific Reviewer for the Scientific Programme Committee for the CIRSE Annual Meeting 2020, 2021, 2022 and 2023.

Research Expertise

Description

Professor Ryan practices in the specialty of Interventional Radiology, a technology and medical device driven specialty that involves performing minimally invasive surgical procedures with specialist medical devices under radiological imaging guidance. He has been actively involved in clinical research for over 25 years, has published and presented more than 170 scientific papers, editorials,, book chapters and articles, with > 2700 citations (Google Scholar; h-index 27, i10 index 48) in the medical literature. Prof Ryan's primary academic interests are in the field of Interventional Oncology which includes tumour embolization and ablation, diagnosis and treatment of haemorrhage, management of visceral organ obstruction, maintenance of vascular access, pain management and palliative therapies. He has a specialist interest in the diagnosis and minimally-invasive treatment of acute life threatening haemorrhage. He described a novel technique for the investigation of patients with occult bleeding that has become a standard technique in Interventional Radiology practice and is widely cited in the radiology literature. He has a particular interest in urological problems associated with gynaecological malignancy and ureteric obstruction and has developed new techniques and management strategies for patients with these problems. He also has particular interest in vascular interventions for all aspects of vascular disease including acute thrombosis, bleeding disorders, arterial and venous obstruction, congenital vascular malformations, and in intra-arterial pharmacological and mechanical thrombolysis. He also has a particular interest in the interventional management and treatment of chronic liver disease and in minimally invasive treatments for hepatocellular carcinoma and transjugular intrahepatic portosystemic shunts (TIPS) for portal hypertension. He was a senior co-author on a widely cited seminal paper on the management of gastric varices. Professor Ryan has been involved in medical device testing, evaluation and development and has worked as a medical advisor to a number of medical device companies. www.researchgate.net/profile/J_Mark_Ryan https://scholar.google.com/citations?view_op=list_works&hl=en&user=cnrp0LcAAAAJ
