BACKGROUND: Venous aneurysms of the upper torso are uncommon in contrast to the abdomen and lower extremities. Mostly silent, they can cause significant morbidity. Large or symptomatic venous aneurysms are generally treated with open resection. To our knowledge, there are no documented cases of head and neck venous aneurysms treated by a hybrid endovascular and open approach. CASE PRESENTATION: A 56-year-old female presented with the complaint of pain and increasing size of a supraclavicular mass...

OBJECTIVE: Endoluminal aortic aneurysm repair is suitable within certain anatomic specifications. This study aims to compare 30-day outcomes of endovascular versus open repairs for juxtarenal and pararenal aortic aneurysms (JAA/PAAs). METHODS: The ACS-NSQIP database was queried from 2012 to 2015 for JAA/PAA repairs. Procedures characterized as emergent were included in the study; however, failed prior repairs and ruptured aneurysms were excluded. The preoperative and perioperative patient characteristics, operative techniques, and outcome variables were compared between the open aortic repair and the endovascular aortic repair groups...

The aim of this study was to screen the biomarkers of diabetic limb arterial stenosis. Fasting blood samples of 40 patients with diabetic limb arterial stenosis (experimental group), 40 diabetes patients (diabetic control group), and 40 healthy individuals (healthy control group) were collected. Protein-chip assay analysis and ELISA were used to detect tumor necrosis factor α, interleukin-6, endothelin-1, calcitonin gene-related peptide and high-sensitivity C-reactive protein in the three groups. Protein-chip array analysis and ELISA found consistent results that endothelin-1, tumor necrosis factor α, interleukin-6 and high-sensitivity C-reactive protein in the experimental group were significantly up-regulated while the expression of calcitonin gene-related peptide was down-regulated compared with the healthy control group (P < 0...

We assessed wound healing in patients on hemodialysis (HD) with critical limb ischemia (CLI). This study enrolled 267 patients (including 120 patients on HD and 147 patients not on HD) who underwent endovascular therapy (EVT) for CLI. The primary endpoint was wound-healing rate at two years. Secondary endpoints were time to wound healing, wound recurrence rate, and limb salvage at two years. The percentage of male and young patients was higher in the HD patients (p < 0.01). A lower patency of the pedal arch after EVT was observed frequently in HD patients (p < 0...

We present the case of a 43-year-old female who suffered a stingray injury to her left ankle. The sting caused occlusion of the dorsalis pedis artery, causing dry gangrene of the medial forefoot. A below knee amputation was recommended but she was transferred for a second opinion. A Prostaglandin E1 infusion was commenced, resulting in alleviation of pain and improvement in perfusion. Amputation of great and second toes was performed, with the head of the first metatarsal preserved and covered via a cross-over skin flap raised from the contralateral leg...

A novel device for distal fixation of a guidewire was tested in regards to deployment and retrieval, deposition in the blood stream and force of fixation in a pig model. Eleven pigs were subjected to full anaesthesia and heparinized to active clotting time 250-350 s. Uninterrupted blood flow during 4 h deposition was assessed by angiography and inspected for thrombus deposition upon retrieval. The force of fixation was investigated up to the level of loss of fixation (displacement force). The device was successfully deployed and retrieved in over 40 cases...

Mahim I Qureshi, Alun H Davies
Transient ischaemic attack secondary to carotid stenosis has the highest risk of stroke recurrence compared with other aetiological subtypes. International guidelines advocate carotid intervention within one to two weeks of the index neurological event. Traditionally, delayed carotid intervention was perceived to be a safer management strategy, yet classic trials of endarterectomy and recent meta-analysis of carotid intervention demonstrate the safety of hyperacute carotid intervention. Data from international studies suggest that targets are not being met, the reasons for which are multifactorial, but patients suffering transient or ocular symptoms are particularly delayed...

The aim of this paper is to comprehensively analyze the literature focused on frequency of the presence of the accessory renal arteries in the human body. A systematic analysis of papers has been made. With regard to ethnicity, the incidence of accessory renal arteries fluctuates from 4% in a Malaysian population to 61.5% in a Brazilian population. The frequency is lowest in eastern and southern Asia (from 4% to 18.4%). In some, not ethnically homogenous populations, wide span of occurrence of accessory renal arteries is described (e...

An automated ankle-brachial index device could lead to potential time savings and more accuracy in ankle-brachial index-determination after vascular surgery. This prospective cross-sectional study compared postprocedural ankle-brachial indices measured by a manual method with ankle-brachial indices of an automated plethysmographic method. Forty-two patients were included. No significant difference in time performing a measurement was observed (1.1 min, 95% CI: -0.2 to +2.4; P = 0.095). Mean ankle-brachial index with the automated method was 0...
