Neurogenic tumors located in the posterior mediastinum, generally require surgery which be confronted with greater risk,therefore, to design the best surgical approach and surgical methods is essential. A 67-year-old female patient had pharyngeal foreign body sensation and dysphagia. Thyroid ultrasound showed the right thyroid had a little nodule, and the left thyroid had a hypoechoic lumps. Neck enhanced CT showd mediastinal mass, esophageal tumor origin or stromal tumor? We used the jugular approach to resect the tumor which eventually diagnosed as schwannoma. The meditational benign tumor with an envelope easy to peel can employ the jugular approach to resect it completely.

Objective: To investigate the practicability and safety of transjugular liver biopsy (TJLB). Methods: Data of 53 cases with transjugular liver biopsy from June 2015 to June 2020 were collected. LABS-100 was used in all patients who underwent transjugular liver biopsy. Among them, 45 cases and eight were biopsied via hepatic vein and intrahepatic segment of the inferior vena cava. The surgical indications, related complications, and postoperative pathological diagnosis were analyzed and summarized. Results: TJLB was successful in all patients, with an average of 2.8 punctures per case. Satisfactory liver tissue and histopathological diagnosis was obtained in all patients. Two cases developed a cervical hematoma that was improved spontaneously, and one patient developed an intrahepatic hematoma that was improved after conservative treatment. Conclusion: TJLB is a practical and safe method for patients with contraindications to percutaneous liver biopsy.

OBJECTIVETo study the duration of prourokinase gene expression in vein grafts and the role of the prourokinase gene in protecting vein grafts from neointimal hyperplasia.

METHODSFifty-four Wistar rats were used in this study. In each rat, the jugular vein was excised and distended for 30 minutes using a solution containing either Adv(5)-CMV (control group) or Adv(5)-CMV/Pro-UK (treatment group). Next, the jugular vein was reversed and interposed into the divided carotid artery of the same rat. On the 14th day after transfection, vein grafts of the control group were collected in order to perform a fibrinolysis test for prourokinase (Pro-UK) activity. On the 2nd, 7th, 14th, 28th, and 60th day, the vein grafts of the treatment group were likewise collected in order to detect prourokinase activity. On the 28th day, the vein grafts of both groups were explanted to evaluate the (3)H-TDR incorporation so that pathologic analysis could be performed.

RESULTSPro-UK activity could not be detected in the control group, while in the treatment group, the Pro-UK activity could be detected from the 2nd day onwards, peaking on the 7th day and declining from the 14th day, but yet persisting at a low level for a further month. The amount of (3)H-TDR incorporated in the control group was higher than that in the treatment group. Pathologic analysis demonstrated that vein grafts of both groups exhibited wall thickening, but that the degree of graft neointimal hyperplasia and reduction of the graft lumen was greater in the control group than that in the treatment group. The occlusion rate of grafts in the control group was 20%. All grafts in the treatment group were patent.

CONCLUSIONSPro-UK gene transfer before vein grafting in vitro results in a high level of gene expression in the vein graft from the 7th day to 14th day. And its gene expression in the vein graft could reduce neointimal hyperplasia in the vein graft.

Epithelioid hemangioendothelioma (EHE) is a relatively rare and moderately aggressive type of vascular tumor. We describe a case of EHE that presented in a 24-year-old woman as a palpable nodule in the left cervical area. Radiological examinations and fine-needle aspiration cytology led to a preliminary diagnosis of metastatic lymphadenopathy with an unknown primary site. However, during surgery, we determined that the nodule was an intra-vascular tumor arising from the left internal jugular vein. The histopathological examination revealed cords of epithelioid endothelial cells distributed in a hyaline stroma, compatible with a diagnosis of EHE.

OBJECTIVETo discuss the method of microsurgical treatment for jugular foramen tumor (JFT).

METHODSTen patients with dumbbell-shaped JFTs who were microsurgically treated by the same group were retrospectively studied, the surgical approaches includes infratemporal approach and modified far lateral approach according to tumors' size, blood feeding, hearing and growth manner. Cranial nerve function, pre- and postoperative complications, follow-up data were presented and discussed.

RESULTSGross total tumor removal was achieved in 7 patients, subtotal removal in 2 cases, partial removal in 1 case, postoperative cerebrospinal fluid leaking in 1 cases, postoperative new cranial nerve defects in 1 cases, aggravation in 2 cases. Postoperative deficits of the cranial nerves improved in 80 percent of the patients. Favorable facial function in 6 months postoperatively (House-Brackmann grade system in Grade 1 and Grade 2) was noted in 7 of the 10 patients. The postoperative level of hearing was preserved in 3 of the 6 patients with residual hearing. Recurrence was noted in 1 case during the follow-up period.

CONCLUSIONSSurgical total removal of JFT is possible depends on microsurgical operation with the two approaches with lowly additional neurological deficits. The function of preoperative affected cranial nerves can be recovered.

We report a case of central venous stenosis due to a structural deformity caused by a tuberculosis-destroyed lung in a 65-year-old woman. The patient presented with left facial edema. She had a history of pulmonary tuberculosis, and the chest X-ray revealed a collapsed left lung. Angiography showed leftward deviation of the innominate vein leading to kinking and stenosis of the internal jugular vein. Stent insertion improved her facial edema.

OBJECTIVETo investigate the potential cell sources of neointimal cells in autologous vein graft in rat model.

METHODSVein graft neointimal cell origins were investigated using a model of vein-to-artery interposition modal. Slides were stained with hematoxylin and eosin, immunohistochemical staining was also performed with primary antibodies alpha-smooth actin or CD34.

RESULTSNeointimal thickening was greater at the proximal ends (65.2 +/- 4.6) microm and, to a lesser extent, distal ends (64.7 +/- 5.3) microm, in comparison to the middle of the graft (63.5 +/- 5.6) microm. Vein-originating cells survived and make a contribution to neointimal formation within the vein graft, mostly adjacent to the lumen, suggesting an intimate association with endothelial cells, donor arterial smooth muscle cells or circulating progenitor cells.

CONCLUSIONSVein graft neointimal cells arise predominantly from vein-derived endothelial cells, donor arteria smooth muscle cells or circulating progenitor cells. It suggests clinical relevance of stenosis-inhibiting therapies directed at the vein graft or early system pharmacologic administration.

INTRODUCTIONLiver biopsy is considered the definitive investigation in the diagnosis and management of liver disease. This study describes the experience of performing transjugular liver biopsy (TJLB) over the last 9 years in a local single centre.

MATERIALS AND METHODSA retrospective review of consecutive TJLB procedures performed at our institution was conducted. A total of 152 patients (74 males and 78 females), with a mean age of 47.4 years (range, 13 to 83 years) underwent a total of 154 TJLB procedures at our institution between March 2003 and November 2011. The principal indication for TJLB was severe coagulopathy in over 80% of patients. The technical success, number of passes, histological adequacy and complication rates were analysed.

RESULTSThe procedural success rate was 98.7% (152 out of 154 procedures). Adequate material for diagnosis was obtained in 149 out of 152 (98.0%) technically successful procedures. There was procedure related morbidity in 8 patients (5.2%) of which all but one were self-limiting requiring no further intervention. We also performed hepatic venous pressure gradient (HVPG) measurements in 19% of patients at the time of TJLB.

CONCLUSIONTJLB performed at our institution is a safe and reliable technique in patients in whom traditional percutaneous liver biopsy may be hazardous. TJLB has a high technical success rate as well as a high diagnostic yield with a low complication rate. TJLB also has the added benefit of performing HVPG, which is of increasing importance in management and prognostication of chronic liver disease.
