The flushing phenomenon may represent a physiologic or a pathologic reaction. Although flushing is usually benign, it is prudent that the physician remains aware of potentially life-threatening conditions associated with cutaneous flushing. A thorough investigation should be performed if the flushing is atypical or not clearly associated with a benign underlying process. The diagnosis often relies on a pertinent history, review of systems, physical examination, and various laboratory and imaging modalities, all of which are discussed in the 2 articles in this continuing medical education series...

OBJECTIVE/BACKGROUND: The objective was to assess the mid-term results of pharmacomechanical catheter-directed thrombolysis (PCDT) for symptomatic acute and subacute inferior vena cava (IVC) thrombosis; the risk factors of early thrombosis recurrence and iliocaval patency were also evaluated. METHODS: From January 2010 to December 2015, 54 patients (33 men; mean age 47.1 years) with symptomatic acute and subacute IVC thrombosis were treated with PCDT. Primary technical success (clot lysis ≥ 50% after PCDT), stent-assisted technical success (residual stenosis < 30% after stenting), clinical success (freedom from thrombosis recurrence within 30 days), complications, frequency of post-thrombotic syndrome (PTS; Villalta score ≥ 5), and iliocaval patency were recorded at follow-up evaluation...

Obesity is a metabolic syndrome leading to several health problems such as hypertension, heart attack, type II diabetes, and even cancer. Carbonic anhydrase VA (CAVA) is a mitochondrial enzyme which is directly associated with the glucose homeostasis and considered as a promising target for obesity and other associated diseases in humans. So far, numerous inhibitors have been designed to inhibit the catalytic activity of CAVA with an assumption for its possible therapeutic uses against type II diabetes and other metabolic diseases...

This clinical report details the results of endovascular treatment of symptomatic superior vena cava syndrome due to central vein stenosis or obstruction (CVSO) by stent angioplasty in patients with dialysis-dependent end-stage renal disease. A 3-year retrospective review of two institutional registries identified 25 chronic hemodialysis patients (17 men, 8 women) affected by CVSO who received endovascular treatment. The majority of the patients (n = 19) presented with symptomatic arm, breast, and facial swelling; and 6 patients presented with dialysis-access dysfunction and venous-line hypertension...

An 83-year-old man was admitted with a chief complaint of exacerbation of dyspnea. His blood oxygen saturation was 90% in the recumbent position despite oxygen therapy, and it dropped to less than 80% when the patient attempted to sit upright. A computed tomography scan revealed a giant hepatic cyst compressing the right atrium and the inferior vena cava. After percutaneous drainage, the oxygen saturation improved and did not change with alteration of the patient's positions from recumbent to sitting or standing...

A case of the Budd Chiary Syndrome (BCS) in a 43-yr-old man with hydatid cyst (HC) in the liver is reported from Imam Ali Hospital, Kermanshah, western Iran in 2016. This case was complicated by inferior vena cava (IVC) thrombosis, right atrial clot and pulmonary emboli. Compression of IVC was the likely mechanism. Abdominal ultrasonography revealed a huge HC located in segments near IVC and caused compression of IVC. Transthoracic echocardiography (TTE) revealed IVC and right atrium thrombosis, however pulmonary emboli was not documented in TTE but intra operative exploration showed multiple clot in main and left pulmonary artery branch...

More than 70 years ago, the phenomenon of "postural shock" in the supine position was described in healthy women in late pregnancy. Since then, avoidance of the supine position has become a key component of clinical practice. Indeed, performing pelvic tilt in mothers at term to avoid aortocaval compression is a universally adopted measure, particularly during cesarean delivery. The studies on which this practice is based are largely nonrandomized, utilized a mix of anesthetic techniques, and were conducted decades ago in the setting of avoidance of vasopressors...

BACKGROUND: Assessment of volume status and differentiating "underfill" and "overfill" edema is essential in the management of patients with nephrotic syndrome (NS). OBJECTIVES: Our aim was to evaluate the volume status of NS patients by using different methods and to investigate the utility of bioelectrical impedance analysis (BIA) in children with NS. METHODS: The hydration status of 19 patients with NS (before treatment of NS and at remission) and 25 healthy controls was assessed by multifrequency BIA, serum N-terminal-pro-brain natriuretic peptide (NT-proBNP) levels, inferior vena cava (IVC) diameter, left atrium diameter (LAD) and vasoactive hormones...

Pacemaker-induced superior vena cava syndrome (SVCS) is a rare but incapacitating adverse event that can occur years after implantation. Inasmuch as it is a rare disease, there is no consensus about its treatment. The most widely used option is balloon angioplasty and venous stent implantation, with preservation of the lead or previous extraction and subsequent reimplantation after the procedure, which is associated with new episodes of thrombosis. The epicardial implantation reduces the risk of thrombosis...

Abernethy malformation, also termed congenital portosystemic shunt and congenital absence of portal vein is the result of malformation of the splanchnic venous system. Congenital portosystemic shunts are divided into extra- and intrahepatic shunts. Two shunts have been defined: Type I is characterized by the complete diversion of portal blood into the vena cava with an associated congenital absence of the portal vein. Type II is defined by an intact but diverted portal vein through a side-to-side, extrahepatic connection to the vena cava...

Solitary fibrous tumours are a rare group of tumours that originate from connective tissues such as the pleura and mediastinum. When growing within the thoracic cavity these tumours exert pressure on vital organs and large vessels. We have successfully operated on two patients with large solitary fibrous tumours and managed the pathophysiological changes manifested as superior vena cava syndrome resulting from these tumours.

BACKGROUND: Unroofed coronary sinus syndrome (URCSS) is a spectrum of cardiac anomalies in which part (partial type) or the entire common wall (complete type) between the coronary sinus (CS) and left atrium is absent. It is commonly associated with a persistent left superior vena cava (PLSVC). The PLSVC can even anomalously connect to the left atrium in complete type anomaly. URCSS has been reported to be associated with delayed diagnosis and life-threatening cerebral injury. The purpose of the present study was to review our experience with surgical correction of this often-concealed malformation and discuss methods for reducing diagnostic omission...

Background In patients with chronic kidney disease (CKD), prevalence of sleep apnoea syndrome (SAS) is reported to be markedly high. However, the factors associated with severity of SAS in such patients rarely have been reported. Methods This was a cross-sectional study of 100 stable non-dialysis patients with CKD who attended a CKD educational programme from April 2014 to August 2015. Diagnosis of SAS and its severity were assessed using a type-3 portable monitor. Results Eighty-six men and 14 women with a mean age of 71...

Persistent left superior vena cava (PLSVC) is a rare disorder which is asymptomatic and hence is usually discovered while performing interventions through the left subclavian vein. We present a case of a 78-year-old male who was undergoing elective placement of a permanent pacemaker for tachycardia - bradycardia syndrome with post-conversion pauses of up to nine seconds. After achieving access through the left subclavian vein the wire kept on going on the left side of the chest instead of crossing the midline to the right side...

INTRODUCTION/OBJECTIVES: Nutcracker syndrome, caused by mesoaortic compression of the left renal vein leading to symptoms related to venous hypertension, is an uncommon entity that may require operative intervention. Traditional open transposition of the left renal vein to the vena cava has been shown to have a re-intervention rate of up to 30%, while also having additional morbidity associated with laparotomy. More recently, endovascular stenting has been described in several small series, but have reported stent fracture, thrombosis and migration...
