Arterial thoracic outlet syndrome (TOS) is the least common type of TOS. Patient's symptoms, clinical examination and duplex ultrasonography usually suffice in deciding patient's management. Our proposed treatment strategies are based on the Scher classification. The choice of the procedure and approach should depend on surgeon's experience and need for arterial reconstruction.

BACKGROUND: -Type 2 diabetes (T2DM) is associated with an increased risk of cardiovascular disease (CVD). This can be partly explained by large artery dysfunction, which already occurs in prediabetes ('ticking clock hypothesis'). Whether a similar phenomenon also applies to microvascular dysfunction is not known. We therefore tested the hypothesis that microvascular dysfunction is already present in prediabetes and is more severe in T2DM. To do so, we investigated the associations of prediabetes, T2DM, and measures of hyperglycemia with microvascular function measured as flicker light-induced retinal arteriolar dilation and heat-induced skin hyperemia...

BACKGROUND: Many publications report outcomes of surgical treatment for thoracic outlet syndrome (TOS); however, high-quality reviews and meta-analyses are lacking. This systematic review and meta-analysis summarizes and compares the outcomes and major complications of the surgical procedures for the 3 types of TOS: arterial, venous, and neurogenic. METHODS: MEDLINE, EMBASE, and CINAHL databases, and the Cochrane Database of Systematic Reviews were searched for papers published between January 1980 and February 2015, using the keywords thoracic outlet syndrome, and treatment and surgical...

BACKGROUND: Thoracic outlet syndrome (TOS) causes neurologic symptoms in 95% of cases and vascular symptoms in 5% of cases. Surgical resection is curative. Endoscopic-assisted transaxillary first rib resection has been previously reported. In this study we report a totally endoscopic video-assisted thoracoscopic surgery (VATS) approach using tailored endoscopic instruments. METHODS: Ten patients (8 women; average age, 32.3 ± 5.6 years) with TOS underwent VATS first rib resection following failure of symptom improvement with physiotherapy...

Two distinct terms are used to describe vascular thoracic outlet syndrome (TOS) depending on which structure is predominantly affected: venous TOS (due to subclavian vein compression) and arterial TOS (due to subclavian artery compression). Although the venous and arterial subtypes of TOS affect only 3% and <1% of all TOS patients respectively, the diagnostic and management approaches to venous and arterial TOS have undergone considerable evolution due to the recent emergence of minimally invasive endovascular techniques such as catheter-directed arterial and venous thrombolysis, and balloon angioplasty...

Thoracic outlet syndrome (TOS) is a group of disorders all having in common compression at the thoracic outlet. Three structures are at risk: the brachial plexus, the subclavian vein, and the subclavian artery, producing neurogenic (NTOS), venous (VTOS), and arterial (ATOS) thoracic outlet syndromes, respectively. Each of these three are separate entities, though they can coexist and possibly overlap. The treatment of NTOS, in particular, has been hampered by lack of data, which in turn is the result of inconsistent definitions and diagnosis, uncertainty with regard to treatment options, and lack of consistent outcome measures...

Thoracic outlet syndrome (TOS) is a condition arising from compression of the subclavian vessels and/or brachial plexus. Many factors or diseases may cause compression of the neurovascular bundle at the thoracic outlet. We describe the case of a 41-year-old woman with TOS who presented with vascular venous symptoms. Chest computed tomography (CT) scan showed a cystic mass at the level of cervico-thoracic junction, located between the left subclavian artery and vein, which appeared compressed. The cystic mass was removed through a cervical approach and it was found to be a cyst arising from the thoracic duct compressing and anteriorly dislocating the left subclavian vein...

Thoracic outlet syndrome (TOS) refers to the compression of the neurovascular bundle within the thoracic outlet. Cases are classified by primary etiology-arterial, neurogenic, or venous. In addition to the typical symptoms of arm swelling and paresthesias, headaches have been reported as a potential symptom of TOS. In this report, we describe a patient with debilitating migraines, which were consistently preceded by unilateral arm swelling. Resolution of symptoms occurred only after thoracic outlet decompression...

Thoracic outlet syndrome is a mechanical space problem in which the brachial plexus and/or subclavian vessels are compressed. Arterial compression is least common and almost always associated with a bony anomaly. We present a case of a 49-year-old woman with a prominent first rib which caused a subclavian artery stenosis. There are many options for subclavian artery repair through open surgery. In high-risk patients, minimal invasive techniques are favorable. To date, few case reports exist on an endovascular artery repair combined with open first rib resection...

OBJECTIVES: In ankylosing spondylitis (AS) patients, cardiac and vascular involvement may manifest as atherosclerosis and coronary artery disease. Systemic inflammation, oxidative stress, increased low-density lipoprotein (LDL) cholesterol and decreased high-density lipoprotein (HDL) cholesterol constitute a significant risk for atherosclerosis. This study investigated the relationship between carotid intima-media thickness (CIMT), LDL/HDL ratio, total oxidant status (TOS; an indicator of oxidative stress) and ischemic modified albumin (IMA; an ischemic marker in AS patients)...

BACKGROUND: The aim of this study was to investigate the potential protective effect of ukrain on an experimental kidney injury model induced by ischemia and reperfusion (IR) in rats. MATERIAL AND METHODS: A total of 24 male Sprague-Dawley rats were equally and randomly separated into three groups as follows: group-1: controls (C; only laparotomy); group 2: renal ischemia-reperfusion (IR; occlusion of the renal artery for 30 min and 2 h of reperfusion); and group 3: ukrain treatment and IR applied group (U + IR; occlusion of the renal artery for 30 min and 2 h of reperfusion; ukrain was intraperitoneally administered 1 h before the IR process)...

Thoracic outlet syndrome is comprised of symptoms resulting from a compression of the neurovascular structures that pass through the intra-scalene triangle. This condition poses challenges in diagnosis due to the syndrome's vague definition, which only identifies the location of pathology without identifying which structures are specifically compromised. Thoracic outlet syndrome is categorized into vascular or neurogenic types with vascular cases subcategorized as arterial or venous and neurogenic cases subcategorized as true or disputed...

Neurogenic thoracic outlet syndrome (NTOS) is the most common type of TOS. Typically it results from impingement of the neurovasculature as it passes between the anterior and middle scalene muscles; this classic anatomical relationship being the foundation of clinical diagnosis. Positional testing relies on vascular compromise occurring when the subclavian artery is compressed in this space. This study describes several anatomical variations observed in this relationship. Sixty-five cadavers (35m/30f) were assessed to determine the frequency and extent of brachial plexus branching variants...

AIMS: Cerebral ischemia reperfusion (IR) injury is a process in which oxidative and apoptotic mechanisms play a part. Neuroprotective agents to be found could work out well for the efficient and safe minimization of cerebral IR injury. Crocin is a strong antioxidant agent; however the influence of this agent on the experimental cerebral ischemia model has not been studied extensively and thus it is not well-known. The objective of our study was to investigate the antioxidant, antiapoptotic and protective effects of crocin on the global cerebral IR induced by four-vessel occlusion...

BACKGROUND: Renal injury is an important complication of infrarenal aortic occlusion (IAO), which is mainly encountered during the postoperative period. Aortic clamping procedure may lead to turbulent blood flow and eventually vasoconstriction at renal arterial level of the abdominal aorta. IL-18BP has well-known antioxidant and anti-inflammatory properties. In this study, we aimed to determine whether IL-18BP has anti-inflammatory, antiapoptotic, antioxidant, and protective effects on acute kidney damage induced by IAO rat model...

OBJECTIVES: Growing evidence suggests that oxidative stress is one of the factors contributing to subarachnoid haemorrhage (SAH)-induced cerebral vasospasm. SAH-induced cerebral vasospam alters thioredoxin (Trx) cycle enzymes and thioredoxin-interacting protein (TXNIP) as an important endogenous antioxidant system. In this study, we have explored the effects of telmisartan on the vascular morphological changes, endothelial apoptosis, tissue oxidative stress status and the level of Trx cycle enzymes/ TXNIP in a rabbit SAH model...
