A 67-year-old woman was detected stage III B adenocarcinoma of the left lung, with epidermal growth factor receptor(EGFR) -mutation. Since chest computed tomography showed enlarged lymph nodes in stations 7 and 1R-4R, radiochemotherapy was recommended. However, she declined radiochemotherapy and the chemotherapy after tumor reduction surgery was chosen. She underwent resection of the left lower lobe and lingular segment, and mediastinal lymph node dissection through a posterolateral thoracotomy by extended bronchoplasty(type C) due to the extranodal invasion of lymph nodes to the lingular segmental bronchus...

After Thoracic Endovascular Aortic Repair (TEVAR) for chronic type B aortic dissection (cTBD) the patency of the false lumen is quite common and its presence is associated with the risk of developing complications and is a predictor of death by aortic rupture. We report a case of a patient treated in emergency for the rupture of the false lumen in cTBD. He had previous TEVAR with persisting distal dissection and retrograde reperfusion of the false lumen. We performed an original endovascular treatment with graft relining and false lumen occlusion with a home-made "candy plug" obtained with two commercially available stent grafts...

: Closure of the proximal tear by Thoracic Endovascular Aortic Repair (TEVAR) at the acute phase appears to be an safe effective treatment to prevent aneurysmal degeneration type B dissection. However, it appears to be inefficient in up to a third of the patient. We report the technical aspects of our experience with patients undergoing secondary open repair after TEVAR for dissecting thoraco-abdominal aneurysm despite early closure proximal tear by TEVAR. METHODS: During a period of 5 years, 96 patients presenting acute Type B Aortic Dissections (TBAD) were treated by TEVAR and followed-up in our institution...

BACKGROUND AND OBJECTIVES: We determined the rates of initial lymph node metastasis following curative resection of mass-forming type-intrahepatic cholangiocarcinoma (ICC) in patients with and without hepatitis virus infection. METHODS: We enrolled 87 patients between January 2000 and December 2013 with ICC without preoperative lymph node metastasis and without lymph node dissection. Patients included 32 who were seropositive for hepatitis B or C virus (virus group) and 55 who had no evidence of hepatitis virus infection (nonvirus group)...

OBJECTIVE: Marfan syndrome (MFS) leads to aortic root aneurysm, while descending thoracic aortic aneurysm (TAA) occurs less commonly. Abdominal aortic aneurysm (AAA) is rarely reported in MFS. Risk factors for AAA are poorly understood and there are no guidelines for AAA screening in MFS. We sought to characterize AAA among Marfan patients in our center. METHODS: The records of 12 adults with MFS and AAA disease were reviewed. Clinical features, imaging, operative reports, and outcomes were analyzed...

OBJECTIVE: Managing symptomatic chronic type B aortic dissection (SCTBAD) by the Streamliner Multilayer Flow Modulator (SMFM) stent (Cardiatis, Isnes, Belgium) is akin to provisional structural support to induce complete attachment of the dissection flap, but with the ability of aortic remolding. This study investigated the SMFM's capability to enact healing of SCTBAD. METHODS: Clinical data for 12 cases comprising preoperative and postoperative treatment of SCTBAD were obtained from a multicenter database hosted by the Multilayer Flow Modulator Global Registry, Ireland...

BACKGROUND: In Zimbabwe, cases of human African trypanosomiasis (HAT) are caused by the unicellular protozoan Trypanosoma brucei, sub-species T. b. rhodesiense. They are reported from the tsetse-infested area in the northern part of the country, broadly corresponding to the valley of the Zambezi River. Tsetse-transmitted trypanosomes, in particular T. congolense and T. vivax, also cause morbidity and mortality in livestock, thus generating poverty and food insecurity. Two species of tsetse fly, Glossina morsistans morsitans and G...

AIMS: Risk models that use a single aortic diameter threshold have failed to successfully predict acute type B aortic dissection (TBAD). We sought to identify meaningful age-indexed anatomical variables to predict TBAD risk. METHODS AND RESULTS: A geometric deformable model, consisting of virtual elastic balloons that inflate inside a vessel lumen, was developed to quantify thoracic aorta geometry. In the presence of TBAD, true and total artery lumen morphology were assessed...

BACKGROUND: The high-risk patient cohort of uncomplicated type B aortic dissections (uTBADs) needs to be clarified. We compared uTBAD patients treated with best medical treatment (BMT), with and without aortic growth, from the Acute Dissection Stent Grafting or Best Medical Treatment (ADSORB) trial database. Furthermore, we looked for trends in outcome for aortic growth and remodeling after BMT and thoracic endovascular aortic repair (TEVAR) and BMT (TEVAR+BMT). METHODS: BMT patients with available baseline and a 1-year follow-up arterial computed tomography scan were identified...

PURPOSE: To describe the use and 6-month outcomes of the octopus endograft technique to reconstruct renovisceral arteries arising from the false lumen (FL) of a type B aortic dissection after thoracic endovascular aortic repair (TEVAR). CASE REPORT: A 46-year-old man post TEVAR for type B aortic dissection was admitted with persistent back pain and a rapidly expanding residual dissection. The celiac and left renal arteries arose from the FL and the superior mesenteric artery from both lumens, with the FL as its main supply...

Paragangliomas are highly vascularized usually benign neoplasms originating from the sympathoadrenal and parasympathetic paraganglia of the autonomic nervous system. When resectable, the management of these tumors consists of surgical ablation preceded by transarterial embolization. The aim of this article is to describe a novel treatment strategy combining intralesional percutaneous embolization with dissection using ultrasound scissors. The case of a 74-year-old women presenting with a Shamblin type III carotid body paraganglioma is presented...

CD24 expression has been implicated in the oncogenesis of multiple types of cancer and high tumor expression is considered a poor prognosis factor; however, the role of CD24 in oral cancer progression is unknown. Unlike other cancer types, we found that higher CD24 levels in human oral cancers are correlated to lower clinical stage and better overall survival. We then dissected the role of CD24 and mechanisms in oral cancer pathogenesis in mice using a genetic strategy and demonstrated that CD24 deficiency increased the oral cavity tumor burden in response to the carcinogen 4-nitroquioline 1-oxide (4-NQO)...

Esophageal necrosis after descending aortic dissection has been described but with no reports of successful treatment. A 66-year-old man with aortic dissection extending from the left subclavian artery through the common iliac arteries subsequently experienced esophageal necrosis. He underwent thoracic esophagectomy, cervical end esophagostomy, and open gastrostomy tube placement. Gastrointestinal continuity was established with a gastric tube conduit in the substernal plane. An oral diet was tolerated after reconstruction...

Introduction Despite its FDA approval and incorporation into the National Comprehensive Cancer Network (NCCN) treatment guidelines, ramucirumab (RAM) is associated with a drug acquisition cost that is substantially higher than other approved options. Given its substantial cost, the presence of a viable alternative treatment option, and its minimal survival improvement, the usefulness of RAM in clinical practice has been called into question. Areas covered In this paper, we outline the cost, benefits, and economic implications of RAM from a US perspective, as it is used in the treatment of mCRC...
