The most common application of radioembolization is in the treatment of primary and secondary liver tumors, and the most common radioisotope is Yttrium-90. This form of treatment has proven to be successful in achieving reduction of tumor size and ultimately improving survival. Fatigue and nausea/vomiting are the most common side effects related to radioembolization and are usually self-limiting. This report describes a case of abdominal pain caused by shunting of yttrium-90 microspheres to the anterior abdominal wall via a patent hepatic falciform artery. This case highlights the need for vigilant angiography and awareness of the falciform artery with prophylactic embolization when necessary/warranted.
A 68-year-old man with a history of metastatic colorectal carcinoma underwent left hepatic lobectomy and right hepatic wedge resection as initial treatment of his metastatic disease. He subsequently underwent right lobar radioembolization for treatment of a segment 8 lesion. At 6 weeks postembolization, he developed hepatic dysfunction which rapidly progressed to fulminant liver failure. A liver biopsy revealed hepatic venous obstruction and fibrosis. The patient died 14 weeks after radioembolization.
Hepatic abscess is a rare complication of yttrium-90 radioembolization of hepatic tumors that most commonly occurs in patients with a history of biliary intervention. Patients usually present several weeks after therapy with pain, nausea, vomiting, and fever. Cross-sectional imaging is necessary in cases of suspected abscess to ensure prompt diagnosis and to help plan treatment, which involves antibiotics and percutaneous drainage.
Biliary complications following yttrium-90 (90Y) radioembolization are rare, and radiation-induced cholecystitis requiring intervention represents an even smaller proportion of these complications, reportedly occurring in fewer than 1% of patients treated with 90Y [1]. However, its implications are serious, as the treatment of radiation cholecystitis may require cholecystectomy in patients otherwise considered poor surgical candidates. While biliary complications such as intrahepatic biliary strictures or bilomas may be unavoidable in the course of treating hepatic malignancies due to local field effects of radiation, radiation cholecystitis results from non-target embolization of radioactive microspheres. Meticulous attention to anatomic detail and catheter position may be adequate in preventing this avoidable complication. Herein we discuss the clinical, radiographic, and pathologic findings, as well as the outcome, of a patient who experienced radiation cholecystitis following 90Y radioembolization.
Gastric ulceration is a relatively uncommon but well-described complication of yttrium 90 (Y90) radioembolization therapy in the locoregional treatment of hepatic tumors. Meticulous attention to vascular anatomy, an assessment of antegrade hepatic arterial flow, and knowledge of the dynamic embolic effect of the chosen Y90 particulate at treatment are requirements to reduce the risk of nontarget embolization to gastrointestinal structures. Radiation-associated gastrointestinal ulceration is difficult to treat, and may be associated with gastrointestinal bleeding, bowel obstruction, and perforation. Surgical excision of the involved segment with bypass may be necessary. The increased use of coil embolization of at-risk vessels combined with administration of Y90 particulates with minimal embolic effect has reduced the incidence of radioembolization associated gastrointestinal ulceration.
Background. Hepatic arterial therapy (HAT) has been proven to be effective at palliation of hormonal symptoms of metastatic neuroendocrine tumors (NETs), as well as a means of cytoreduction. Recently, the newer modalities of yttrium-90 and drug-eluting beads with doxorubicin (DEBDOX) have been reported to be effective in the treatment of metastatic NETs. The aim of this study was to compare the safety, efficacy, and cost of selective internal radiation with DEB therapy.
Objectives. The aim of this study was to assess the effectiveness of SPECT/CT for volume measurements and to report a case illustrating the major impact of SPECT/CT in calculating the vascularized liver volume and dosimetry prior to injecting radiolabelled yttrium-90 microspheres (Therasphere). Materials and Methods. This was a phantom study, involving volume measurements carried out by two operators using SPECT and SPECT/CT images. The percentage of error for each method was calculated, and interobserver reproducibility was evaluated. A treatment using Therasphere was planned in a patient with three hepatic arteries, and the quantitative analysis of SPECT/CT for this patient is provided.
Minimally invasive techniques used in the evaluation and treatment of colorectal liver metastases (CRLMs) include ultrasonography (US), computed tomography, magnetic resonance imaging, percutaneous and operative ablation therapy, standard laparoscopic techniques, robotic techniques, and experimental techniques of natural orifice endoscopic surgery. Laparoscopic techniques range from simple staging laparoscopy with or without laparoscopic intraoperative US, through intermediate techniques including simple liver resections (LRs), to advanced techniques such as major hepatectomies. Hereins, we review minimally invasive evaluation and treatment of CRLM, focusing on a comparison of open LR (OLR) and minimally invasive LR (MILR). Although there are no randomized trials comparing OLR and MILR, nonrandomized data suggest that MILR compares favorably with OLR regarding morbidity, mortality, LOS, and cost, although significant selection bias exists. The future of MILR will likely include expanding criteria for resectability of CRLM and should include both a patient registry and a formalized process for surgeon training and credentialing.
