RESUMO
AIM: To evaluate the authors' experience with interventional radiological management of tumour rupture in hepatocellular carcinoma (HCC) in a Western population. MATERIALS AND METHODS: A retrospective review was performed of all consecutive patients treated at a single institution with transcatheter embolisation for ruptured HCC between 2000 and 2013. Patient age, sex, aetiology of liver disease, degree of underlying liver dysfunction, and clinical presentation were assessed. Embolisation was performed in a selective fashion when possible. Success, complications, and survival were assessed. RESULTS: Twenty-three patients were treated with embolisation for ruptured HCC. Of these patients, nine, nine, and five patients were Child-Pugh Class A, B, and C respectively. Embolisation was successful in 22 patients; one patient remained haemodynamically unstable and transfusion dependent despite embolisation. No major complications occurred. Median survival time was 260 days and the 30 day and 1 year survival rates were 83% and 45%, respectively. Child-Pugh class B or C (p = 0.04), Model for End-Stage Liver Disease score greater than 10 (p = 0.04), lobar embolisation (p = 0.04), and presence of portal vein thrombosis (p = 0.01) were significantly associated with worse prognosis. CONCLUSION: Transcatheter embolisation is effective at controlling haemorrhage in patients with ruptured HCC. Although major procedural complications are low, embolisation should proceed with an understanding of poor prognosis in patients with decompensated liver disease. Superselective embolisation is associated with improved prognosis and should be performed when feasible.

Infant femoral arterial access is an essential part of interventional procedures, hemodynamic monitoring, and support of critically ill patients. Due to small luminal diameter, superficial location, mobility, and increased risk of vasospasm, dissection, and thrombosis, femoral artery access in the infant is a technically demanding procedure. The purpose of this manuscript is to describe an approach to successful common femoral arterial access and arteriography in infants including common pearls and pitfalls.

The purpose of this study was to demonstrate the feasibility of percutaneous fluoroscopically-guided transcervical retrograde access into the thoracic duct following unsuccessful transabdominal cisterna chyli cannulation to perform thoracic duct embolization for the treatment of chylothorax. Five patients, including three (60%) women and two (40%) men, with median age of 62 years, underwent percutaneous transcervical thoracic duct access and embolization after failed transabdominal cisterna chyli cannulation for the treatment of chylothorax. In all patients, fluoroscopically-guided percutaneous transcervical retrograde access into the distal thoracic duct was achieved using a 21-gauge needle and an 0.018-inch wire. Following advancement of a microcatheter, retrograde lymphangiography was performed to identify the location of thoracic duct injury. A combination of 2:1 ethiodized oil to cyanoacrylate mixtures, platinum microcoils, or stent-grafts were used to treat the chylous leaks. Technical successes, procedure durations, fluoroscopy times, blood losses, immediate adverse events, clinical successes, and follow-up durations were recorded. Technical success was defined as cannulation of the distal thoracic duct using a transcervical approach followed by treatment of the thoracic duct injury. Adverse events were classified according to the Society of Interventional Radiology guidelines. Clinical success was defined as resolution of the presenting chylothorax. Percutaneous transcervical retrograde thoracic duct access and treatment was technically successful in all patients (n=5). Median procedure duration was 173 minutes (range: 136-347 minutes) with a median fluoroscopy time of 94.7 minutes (range: 47-125 minutes). Median blood loss was 10 mL (range: 5-20 mL). No minor or major adverse occurred. Clinical success was achieved in all patients (n=5). Median follow-up was 372 days (range: 67-661 days). Percutaneous fluoroscopically- guided transcervical retrograde thoracic duct access is an effective and safe method to perform thoracic duct embolization following unsuccessful transabdominal cisterna chyli cannulation for the treatment of chylothorax.
