I am an interventional radiologist with a particular interest in interventional oncology. I perform a wide range of procedures including ablations of the lung, liver, kidney, bone, and other areas in the body, chemoembolization, embolization, and radioembolization of tumors, biopsies, drainages, and interventions on both the venous and arterial sides. I was the first physician to perform SIR-spheres radioembolization for metastatic tumors to the liver within the VA hospital system, and have been recognized for my teaching of trainees. I perform research in areas of the application of big data to medicine as well as treatment of lung and liver cancers.

Liver tu"TACE" because of its inconsistent use in the literature (ie, to abbreviate different terms). Please note that "TACE" has been replaced with "transcatheter arterial chemoembolization" or simply "chemoembolization" as appropriate throughout the manuscript. Please verify these changes.-->mors may receive blood supply from parasitized extrahepatic arteries (EHAs) that also perfuse skin or from hepatic arteries located near the origin of the falciform artery (FA), which perfuses the anterior abdominal wall. To vasoconstrict cutaneous vasculature and prevent nontarget deposition, ice packs were topically applied to at-risk skin in nine chemoembolization treatments performed via 14 parasitized EHAs, seven chemoembolization treatments near the FA origin, and five radioembolization treatments in cases in which the FA could not be prophylactically coil-embolized. No postprocedural cutaneous complications were encountered.

  • Superselective Internal Radiation With Yttrium-90 Microspheres in the Management of a Chemorefractory Testicular Liver Metastasis CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY Sideras, P. A., Sofocleous, C. T., Brody, L. A., Siegelbaum, R. H., Shah, R. P., Taskar, N. 2012; 35 (2): 426-429


    We treated a patient with biopsy-proven, chemotherapy-resistant testicular cancer liver metastasis using Y-90 selective internal radiation treatment. We chose yttrium-90 rather than surgery and ablation due to tumor location and size as well as the patient's clinical history. The result was marked tumor response by positron emission tomography and computed tomography as well as significant improvement of the patient's quality of life accompanied by a substantial decrease of his tumor markers.

  • Asymptomatic Liver Abscesses Mimicking Metastases in Patients after Whipple Surgery: Infectious Complications following Percutaneous Biopsy-A Report of Two Cases. Case reports in hepatology Zhang, K. K., Maybody, M., Shah, R. P., Vakiani, E., Getrajdman, G. I., Brody, L. A., Solomon, S. B. 2012; 2012: 817314-?


    We present two cases of hepatic abscesses that mimicked metastases in patients having undergone Whipple surgery. Both patients had similar imaging features on computed tomographic (CT) scan and ultrasound, and at the time of referral for biopsy neither patient was clinically suspected to have liver abscess. Both patients underwent biopsy of liver lesions and developed postprocedural infectious complications.

  • Cystic Artery Localization with a Three-dimensional Angiography Vessel Tracking System Compared with Conventional Two-dimensional Angiography JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY Wang, X., Shah, R. P., Maybody, M., Brown, K. T., Getrajdman, G. I., Stevenson, C., Petre, E. N., Solomon, S. B. 2011; 22 (10): 1414-1419


    During transcatheter hepatic therapy, the cystic artery feeding the gallbladder may inadvertently be exposed to tumor therapy. Localization of the cystic artery may help prevent exposure. The objective of this study was to compare the application of a vessel tracking system software based on three-dimensional (3D) angiography versus standard two-dimensional (2D) angiography for identifying the cystic artery and its origin.A software system that can rapidly localize the cystic artery from a 3D common hepatic angiogram was applied in 25 patients and was compared with manual localization of the cystic artery with conventional 2D digital subtraction common hepatic angiograms.With the vessel tracking software prototype, 28 cystic arteries were retrogradely tracked in 25 of 25 cases. The origin sites were correctly located by the software in 27 of 28 cystic arteries, with one mistracked as a result of streak artifact. By contrast, on standard 2D hepatic angiography, the cystic artery was deemed visible with certainty in 12 of 25 cases (P < .001). The vessel tracking system revealed a 56% prevalence of extraanatomic distribution by the cystic artery, with the most common supply going to segment 5 liver parenchyma.The 3D vessel rapid tracking system has advantages over conventional 2D hepatic angiography in revealing the cystic artery and its origin site. It is also an important tool to identify the complete distribution of the cystic artery without superselective angiography. Supply to adjacent hepatic parenchyma or tumor by the cystic artery is not insignificant and should be considered during hepatic therapies.

  • Arterially Directed Therapies for Hepatocellular Carcinoma AMERICAN JOURNAL OF ROENTGENOLOGY Shah, R. P., Brown, K. T., Sofocleous, C. T. 2011; 197 (4): W590-W602


    Arterially directed therapies for hepatocellular carcinoma are used for patients who are not candidates for surgery or ablation and for those who need a bridge or down-staging to liver transplantation. These therapies seem to prolong the overall survival when compared with supportive care.Chemoembolization, particle embolization, drug-eluting beads, and radioembolization have been used for locoregional control. This review discusses patient selection, techniques, safety, clinical outcomes, and imaging findings related to these therapies.

  • Hepatic arterial embolization complicated by acute cholecystitis. Seminars in interventional radiology Shah, R. P., Brown, K. T. 2011; 28 (2): 252-257


    Hepatic arterial embolization (HAE) is a treatment used in the management of primary and some metastatic hepatic tumors. Complications of HAE are similar to those seen in other treatments, particularly transcatheter arterial chemoembolization (TACE), but without the possibility for chemotherapy related side effects. Particle reflux into the cystic artery is generally clinically occult but gallbladder ischemia severe enough to require cholecystostomy tube placement can occur. The authors discuss the case of a patient who underwent HAE and subsequently required a cholecystostomy tube due to development of acute cholecystitis.

    Moyamoya syndrome and cerebral aneurysm formation are rare cerebrovascular manifestations of Alagille syndrome. Although previously reported in isolation, occurrence of these complications in a single patient has not been described. We report clinical and imaging features of synchronous moyamoya syndrome and ruptured cerebral aneurysm in a patient with Alagille syndrome.

  • A case of pancreatic islet cell transplantation in a patient with situs ambiguous: anatomical and radiological considerations. Seminars in interventional radiology Shah, R. P., Bui, J. T., West, D. L., Oberholzer, J., Hatipoglu, B. A., Martellotto, J. N., Owens, C. A. 2007; 24 (1): 43-46


    Pancreatic islet cell transplantation is an evolving treatment of severe, refractory type 1 diabetes that has been gaining more use, particularly after one year rates of insulin independence post-transplantation were found to approach 80% under the Edmonton protocol. Islet cell transplantation involves percutaneous delivery of harvested allogeneic β cells into the portal venous circulation for implantation into the liver. We present the case of a 35-year-old woman with type 1 diabetes and situs ambiguous with left isomerism and resultant variant anatomy of her portal venous anatomy who underwent islet cell transplantation, which, to our knowledge, has not been previously reported.
