    © Copyright 2019, Mary Ann Liebert, Inc., publishers 2019. Extrahepatic congenital portosystemic shunts (CPSSs) can be occluded by surgical or endovascular approaches. However, when the estimated portal vein (PV) pressure after the closure is high enough to induce symptoms associated with portal hypertension, partial closure is recommended to avoid life-threatening events. In this study, we attempted laparoscopic partial closure of a CPSS in two patients. Along with intraoperative real-time measuring of the PV pressure and angiography, laparoscopic partial closure was performed to achieve a PV pressure of ≤25 mmHg. Subsequently, the intrahepatic portal system grew in both patients. The partially ligated CPSS closed spontaneously in the first patient. In the second patient, laparoscopic complete closure was performed for the residual CPSS 6 months after the first operation. To our knowledge, this is the first report of laparoscopic partial closure for CPSS. Minimally invasive laparoscopic partial ligation of CPSS is technically feasible and useful when the estimated PV pressure is too high to tolerate one-step complete closure.

Introduction Percutaneous cryoablation has been adopted for small, malignant peripheral pulmonary lesions and has yielded favourable results as a less invasive local treatment. A transbronchial approach may reduce the risks of complications, such as pneumothorax and pleural haemorrhage. A fundamental animal experiment on transbronchial cryoablation was performed to examine its immediate safety and effectiveness. Methods Experimental cryoablation was performed on swine lungs using a rigid cryoprobe, 2.4 mm in diameter. The probe was introduced from the right main bronchus into the distal bronchus via thoracotomy, perforated the end of the conducting bronchus and reached the lung parenchyma. The temperature of the cryoprobe tip reaches approximately a '130°C during freezing and approximately 20°C during thawing. After three freeze-thaw cycles, the cryoprobe was removed. Results No significant haemorrhage was bronchoscopically observed in the airways throughout the experiment. The chronological changes and spatial distribution of the temperature of the pulmonary tissue circumferential to the point of the cryoprobe were similar to those seen with transpleural cryoablation and the less than a '20°C thermal zone seemed to be established within a radius of at least 12 mm. The central destruction zone of alveolar structures was histologically similar to the thermal zone, while the conducting bronchus structure and the accompanying pulmonary artery were not severely affected. Conclusion Experimental transbronchial cryoablation with a rigid cryoprobe could effectively freeze and destroy peripheral lung alveoli without any significant immediate adverse effects. This may suggest the potential clinical application of transbronchial cryoablation for peripheral malignant lung lesions.

    © 2017, Springer Science+Business Media, LLC and the Cardiovascular and Interventional Radiological Society of Europe (CIRSE). A type II endoleak (T2EL) is the most common endoleak after endovascular aneurysm repair (EVAR), and a persistent T2EL has been occasionally associated with aneurysmal enlargement. Typical findings of a T2EL consist of an endoleak cavity with inflow and outflow arteries of aortic branch vessels. However, an atypical T2EL, in which hypertrophied vasa vasorum and enlargement of a thrombosed aneurysm are observed, has no endoleak cavity. We have seen three cases of continuous aortic aneurysmal growth after EVAR caused by atypical T2ELs without endoleak cavities through developed vasa vasorum. In this report, the imaging findings of selective angiography and dynamic computed tomography of these cases are reviewed.
