Postoperative hepatic lymphorrhea is extremely rare and there is no standard treatment for this condition. We report the cases of 3 men, 32-, 56-, and 37-year-old, with postoperative hepatic lymphorrhea, which was refractory to conservative treatment. Transhepatic lymphangiography allowed locating the lymphatic leak and treating it with hepatic lymphatic vessels injection of foam sclerotic agent. This technique seems efficient and safe.
Background
Thoracic duct stenosis or obstruction is one of the causes of chyluria. Although the diagnosis of chyluria is not difficult, treatment is still challenging. Although there have been no standard guidelines for the treatment of chyluria, interventional techniques now offer minimally invasive treatment options for chyluria such as interstitial lymphatic embolization, ductoplasty with balloon, or thoracic duct stenting.
Case presentation
Here, we report a case of chyluria due to obstruction of the junction between the thoracic duct and subclavian vein in a 64 -year- old female patient. The patient was treated with balloon plasty for lymphovenous junction obstruction and interstitial lymphatic embolization for chyluria. However, chyluria was recurrent after 6 months so intranodal lymphangiography was performed. Anterograde thoracic duct was accessed through a transabdominal to the cisterna chyli which showed that the thoracic venous junction was re-obstruction. The patient was successfully treated by placing a uncovered drug-eluting stent with the size of 2.5 mm x 15 mm in length for resolving the thoracic occlusion.
Conclusion
This report demonstrates the feasibility of using thoracic duct stenting in the treatment chyluria due to lymphovenous junction obstruction.
Background: This study aims to report our experience with cerebral aneurysms, which may improve in the treatment with the flow-diverter stent and follow up. Methods: This study was conducted in a consecutive series of 130 patients. 134 procedures were performed for treating these patients in Hanoi Medical University Hospital and Bach Mai Hospital from January 2012 to April 2017. 143 flow diverter stents (Pipeline, FRED and SILK) were used. Aneurysm morphology, stent patency and cerebral parenchyma before and after intervention were analyzed on images of digital subtraction angiography (DSA), computed tomography (CT) and magnetic resonance (MR). The follow-up data after 3-6 months and 12 months were recorded. Results: In 130 patients (31 men, 99 women), aneurysms of internal carotid artery were mostly common (92.6%), especially in cavernous (35.1%) and in para-ophthalmic (40.3%) segments. 83 cases (61.9%) had wide-neck aneurysms, and 16 cases (11.9%) had multiple aneurysms, and only 5 cases (3.7%) had blister-liked aneurysms. Endovascular treatment was successfully performed at rate of 94.8%. In 3 patients, the stent could not be delivered. Mortality and morbidity rates were 1.5% and 3.7%, respectively. MRI and MSCT follow-up at 3 months showed complete or incomplete occlusions of aneurysms was 7.4% or 17.5%, respectively. 3 patients experienced a thromboembolic event (4.3%). Conclusions: Intracranial aneurysms of cavernous and para-ophthalmic segments of internal carotid artery are mostly common with wide-neck and multi aneurysms. Deployment of flow diverter stent is safe and effective with high rate of successful and low procedural complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
