Case 276: Pulmonary Veno-Occlusive Disease and Pulmonary Capillary Hemangiomatosis Disease.

HistoryA 34-year-old man presented to the emergency department of our hospital for progressive shortness of breath and worsening productive cough of 2 weeks duration. He reported a 10-kg weight loss over 4 months but denied experiencing fever, chills, night sweats, or gastrointestinal, musculoskeletal, or neurologic symptoms. His medical history was unremarkable. Although he was a native of Morocco, he had lived in Europe for many years and worked as a truck driver. The patient had a smoking history but had quit smoking 5 years prior to presentation. He denied alcohol abuse or recreational drug use. He did not have any allergies. Besides bilateral clubbing, the physical examination findings were normal. At the time of admission, he had an oxygen (O2) saturation of 87% at ambient air, which increased to 100% with 1 L of O2 administered via a nasal cannula. The blood sample revealed a slight increase in his hemoglobin concentration (18.7 g/dL; normal range, 13.6-17.2 g/dL) and hematocrit level (50.8%; normal range, 39%-49%). His inflammatory parameters were normal, as were his hepatic and renal function. The arterial blood gas test showed partially compensated pulmonary alkalosis (pH, 7.43; normal range, 7.35-7.42; PCO2, 26 mmHg; normal range, 38-42 mmHg; PO2, 89 mmHg; normal range, 75-100 mmHg; bicarbonate level, 17 mEq/L [17 mmol/L]; normal range 22-26 mEq/L [22-26 mmol/L]). The results of the pulmonary function tests were expressed as the percentage of predicted values and were 92% for forced vital capacity, 93% for forced expiratory volume in 1 second, 116% for total lung capacity, and 60% for diffusing capacity of carbon monoxide. Anteroposterior chest radiography and enhanced chest CT were also performed at admission.

Update on transarterial approaches to locoregional treatment in hepatocellular carcinoma.

PURPOSE OF REVIEW: This review explores current knowledge and recent data about vascular-centered locoregional treatments and proposes alternate algorithms. RECENT FINDINGS: Hepatocellular carcinoma represents the sixth most common neoplasm worldwide. Currently, the Barcelona Clinic Liver Cancer (BCLC) staging is the most commonly used in Europe for treatment allocation. According to this classification, European Society for Medical Oncology (ESMO) guidelines currently recommend transarterial chemoembolization for intermediate stage HCC and systemic treatments, such as, sorafenib in more advanced stages. However, strong evidences are still lacking to conclude to the superiority of one technique over another, as the optimal treatment choice remains challenging and should take into consideration more clinical, biological and imaging findings than reported in the BCLC staging system, such as patient age or clinical status, tumor characteristics (including distribution and heterogeneity), tumor vascularization and concomitant portal hypertension or biliary anomalies. SUMMARY: Many controversies remain, in particular, the relative place of bland embolization versus chemoembolization, the clinical benefit of drug-eluting bead chemoembolization (DEB-TACE) over conventional chemoembolization (cTACE), as well as the real place of radioembolization in general setting as well as innovative applications, such as radiation segmentectomy and radiation lobectomy.
