Successful management of intractable chylothorax in Gorham-Stout disease by awake thoracoscopic surgery

Japanese clinical practice guidelines for vascular anomalies 2017

The objective was to prepare guidelines to perform the current optimum treatment by organizing effective and efficient treatments of hemangiomas and vascular malformations, confirming the safety, and systematizing treatment, employing evidence-based medicine (EBM) techniques and aimed at improvement of the outcomes. Clinical questions (CQs) were decided based on the important clinical issues. For document retrieval, key words for literature searches were set for each CQ and literature published from 1980 to the end of September 2014 was searched in Pubmed, Cochrane Library, and Japana Centra Revuo Medicina (JCRM). The strengths of evidence and recommendations acquired by systematic reviews were determined following the Medical Information Network Distribution System (MINDS) technique. A total of 33 CQs were used to compile recommendations and the subjects included efficacy of resection, sclerotherapy/embolization, drug therapy, laser therapy, radiotherapy, and other conservative treatment, differences in appropriate treatment due to the location of lesions and among symptoms, appropriate timing of treatment and tests, and pathological diagnosis deciding the diagnosis. Thus, the Japanese Clinical Practice Guidelines for Vascular Anomalies 2017 have been prepared as the evidence-based guidelines for the management of vascular anomalies.

Surgical management of Gorham-Stout syndrome involving the cervical spine with bilateral pleural effusion: A case report and literature review

Gorham-Stout syndrome (GSS) is a rare disease characterized by spontaneous and progressive osteolysis caused by benign proliferation of lymphatic vessels or capillaries. It most commonly occurs in children or young individuals without any inherited predisposition. GSS most commonly affects the shoulder girdle, pelvis, ribs and skull. Its diagnosis is mainly based on radiological and pathological findings. The present study reports on the case of a 22-year-old male patient diagnosed with GSS involving the C1-T1 vertebrae accompanied by bilateral pleural effusion. Resection of the occipital and cervical vertebral lesions and spinal reconstruction using an internal fixator were successfully performed via the posterior approach. After the surgery, the patient received bisphosphonate treatment and vitamin D supplementation. The pleural effusion gradually decreased. At the 18-month follow-up visit, no evidence of new bone obstruction was present and the patient had no neurological sequelae.

99mTc-SC lymphoscintigraphy and SPECT/CT findings in a case report of Gorham-Stout disease presenting with chylothorax and bone pain

RATIONALE

Gorham-Stout disease (GSD) is a rare disorder characterized by multiple osteolytic lesions, sometimes complicated by chylothorax. The aim of this case report is to introduce a very rare case of Gorham-Stout syndrome, which involved several bones along with chylous pericardial and pleural effusions detected by Tc-sulfur colloid (SC) lymphoscintigraphy and single photon emission computed tomography/computed tomography (SPECT/CT).

PATIENT CONCERNS

A 15-year-old girl presented to our hospital complaining of shortness of breath and bone pain.

DIAGNOSIS

The CT showed multiple osteolytic lesions, left-sided pleural effusion, and pericardial effusion. Tc-SC lymphoscintigraphy showed discontinuation of thoracic duct and tracer accumulation on the left side chest. SPECT/CT revealed increased radioactivity uptake in pleural, pericardial effusions, and some thoracolumbar spines. Diagnostic thoracentesis to identify the nature of pleural effusion and histopathology of biopsy in the right femoral to that of the bone lesion were performed. Based on the clinical information, histopathologic, and radiographic findings, the diagnosis of GSD was made.

INTERVENTIONS

The patient received thoracic duct ligation and bisphosphonates treatment.

OUTCOMES

After receiving thoracic duct ligation and bisphosphonates treatment, the patient's symptoms of bone pain and dyspnea were relieved, and the pericardial and pleural fluid was diminished dramatically. At the 3-month and 9-month follow-up visit, the patient had nearly complete remission without any complication.

LESSONS

The Tc-SC lymphoscintigraphy and SPECT/CT could provide significant value assessing the lymphatic abnormity and evaluating the extent of disease, therefore aiding to guide decision making in the clinic.

Left Functional Pneumonectomy Caused by a Very Rare Giant Intrathoracic Cystic Lesion in a Patient with Gorham-Stout Syndrome: Case Report and Review of the Literature

Gorham-Stout syndrome is an uncommon entity, with few cases reported in bibliography. It consists of osteolytic manifestations affecting various bones and replacing them with lymphangiomatous tissue. With pathophysiology unknown, Gorham-Stout disease affects also cardiorespiratory system usually causing lytic lesions to the bones of the thoracic cage or directly invading the thoracic duct. This is a case report of a unique respiratory manifestation of the disease and a review of its cardiorespiratory complications.

Pulmonary and pleural lymphatic endothelial cells from pediatric, but not adult, patients with Gorham-Stout disease and generalized lymphatic anomaly, show a high proliferation rate

Background

Gorham-Stout disease (OMIM 123880) and generalized lymphatic anomaly are two rare disorders of lymphendothelial growth in which thoracic involvement with chylothorax is a feared complication. Currently it is believed that both disorders are prenatal malformations that progress slowly after birth. Several pharmaceuticals with antiproliferative properties, including interferon-α-2b, rapamycin and propranolol, have however been shown to affect the disease course in some patients. Deeper knowledge of the growth characteristics of these malformations are therefore needed to guide the clinical approach.

Methods

Lymphatic vessels in lung and pleural tissue from both children and adult patients with generalized lymphatic anomaly or Gorham-Stout disease were studied using an immunohistochemical approach, targeting lymphendothelial markers (D2-40/Prox-1) and a proliferation marker (Ki-67).

Results

We found significant proliferation and growth in these lesions in pediatric patients but not in adults. Furthermore, the data may suggest that the disease process is at least partly reversible.

Conclusions

These malformations of the lymphatic system proliferate at a significant rate long after birth, which could suggest that the clinical approach for children should be different from adults.
