Spinal dural arteriovenous fistulas (SDAVFs) are the most common vascular malformation of the spinal cord, causing segmental lesions of the spinal cord due to venous ischemia. Functional outcomes of treatment in SDAVF patients are favorable, but the rate of improvement varies from 25 to 100%, which complicates prediction of the treatment outcome. AIM: the study aim was to identify a relationship between fistula localization and clinical manifestations and evaluate the effect of disease duration and severity of neurological impairments on immediate and long-term treatment outcomes, based on analysis of the literature and own data...

BACKGROUND: Indocyanine green (ICG) videoangiography can be used to delineate the locations of the cortical vessels just prior to dural opening, allowing safe and optimal dural opening. The present clinical series demonstrates the adjunct use of ICG videoangiography to optimize dural opening for the treatment of various cerebrovascular diseases. METHODS: A total of 45 patients underwent surgery for superficial temporal artery-middle cerebral artery bypass (40), arteriovenous malformation (2), and dural arteriovenous fistula (3) between January 2012 and December 2016...

Pulmonary hypertension (PH) is diagnosed using cardiac catheterization and is defined as an elevation of mean pulmonary artery pressure (PAP) greater than 25 mmHg. Although invasive hemodynamics remains the gold standard and is mandatory for disease confirmation, transthoracic echocardiography (TTE) is an extremely useful non-invasive and widely available tool that allows for screening and follow-up, in particular, in the acute setting. TTE may be a valuable alternative, allowing for direct measurement and/or indirect assessment of PAP...

Surgical margin status in cancer surgery represents an important oncologic parameter affecting overall prognosis. The risk of disease recurrence is minimized and survival often prolonged if margin-negative resection can be accomplished during cancer surgery. Unfortunately, negative margins are not always surgically achievable due to tumor invasion into adjacent tissues or involvement of critical vasculature. Herein, we present a novel intra-operative device created to facilitate a uniform and mild heating profile to cause hyperthermic destruction of vessel-encasing tumors while safeguarding the encased vessel...

BACKGROUND: We would like to evaluate causes of Thoracic Endovascular Aortic Repair (TEVAR) failure and conversion to open surgery (COS) in high volume vascular center for open surgery, with low volume TEVAR procedures. METHODS: A total of 8 patients (6 males, mean aged 55.14 years) underwent COS after TEVAR. The indications for conversion to open surgery, intraoperative strategy, as well as early postoperative and mid follow-up results were analyzed. RESULTS: The indications for COS were persistent proximal type I endoleak with progressive aneurysm enlargement in two patients, endoleak type III in one patient, progressive aneurysm enlargement with no endoleak in one patient, stent graft migration in two patients, secondary aorto-esophageal fistula in one patient, secondary aorto-esophageal and aorto-bronchial fistula in one patient, as well as distal progression of the aneurysmal disease in 2 patient...

BACKGROUND: Among patients undergoing non-cardiac surgery, major vascular surgery is associated with a high risk of perioperative myocardial infarction (MI). Currently there are no perioperative MI risk calculators accounting for intraoperative and postoperative risk factors in vascular surgery patients. We aimed to investigate specific risk factors for perioperative MI after major open vascular surgery to determine which patients are at highest risk of MI, and the association of perioperative MI with perioperative transfusion...

Posterior fossa houses very vital and sensitive structures namely midbrain, pons, medulla, and cerebellum. These structures are irrigated by vertebral, posterior inferior cerebellar, anterior inferior cerebellar, and superior cerebellar arteries. Parts of brain located in posterior fossa control important parts of body so any variation pertaining to stenosis, atresia, hypoplasia, fenestration, agenesis, and duplication in the arteries supplying these parts alter the irrigation pattern culminating into various morbid and mortal neurologic disorders...

A detailed molecular characterization of gastric cancer has been revealed by global initiatives and a number of new molecular agents are under investigation. Currently only trastuzumab, a monoclonal antibody for human epidermal growth factor receptor 2 (HER2), is clinically used for HER2 positive advanced gastric cancer patients and ramucirumab, a monoclonal antibody directed against the extracellular ligand-binding domain of vascular endothelial growth factor receptor (VEGFR)2, can be used in second line. However, despite the progress in gastric cancer treatment, the prognosis of stage IV gastric cancer patients remains dismal...

Stroke can affect females very differently from males, and therefore preclinical research on underlying mechanisms and the effects of interventions should not be restricted to male subjects, and treatment strategies for stroke should be tailored to benefit both sexes. Previously, we demonstrated that a multinutrient intervention (Fortasyn) improved impairments after ischemic stroke induction in male C57Bl/6 mice, but the therapeutic potential of this dietary treatment remained to be investigated in females...

BACKGROUND: Aneurysm or pseudoaneurysm is the main vascular complication of Behcet's disease. Most hospitals adopt endovascular treatment. CASE PRESENTATION: We report a case of Behcet's disease with recurrent thoracic aortic aneurysm combined with femoral artery aneurysm. The patient underwent two rounds of endovascular surgery, but developed new aneurysms immediately after surgery. Eventually, the patient died due to rupture of recurrent aneurysm. CONCLUSIONS: For vasculo-Behcet's disease, we suggest performing the operation during the stable period...

OBJECTIVES: Compared with percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) appears to be a promising revascularization strategy for multivessel coronary disease. Trials comparing these treatments have not used second-generation drug-eluting stents (2nd DES). We conducted a retrospective evaluation of both treatments using a propensity score-matched analysis (PSMA). METHODS: A total of 537 patients with three-vessel with/without left-main-trunk coronary artery disease underwent CABG (n = 239) or primary PCI using 2nd DES (298) at a single institution...

The therapeutic goal for peripheral arterial disease and ischemic heart disease is to increase blood flow to ischemic areas caused by hemodynamic stenosis. Vascular surgery is a viable option in selected cases, but for patients without indications for surgery such as progression to rest pain, critical limb ischemia, or major disruptions to life or work, there are few possibilities for mitigating their disease. Cell therapy via monocyte-enhanced perfusion through the stimulation of collateral formation is one of a few non-invasive options...
