Background The endovascular therapy for cerebral venous sinus thrombosis (CVST) is currently accepted as a second-line treatment for patients who have failed or those in whom systemic anticoagulation is contraindicated or in a subgroup of patients presenting with rapid neurologic deterioration. A number of different mechanical and pharmacologic endovascular strategies have been reported, either as separate or combined approaches. These new catheters and aspiration systems have a high power and vacuum capacity, which carries a risk of anemization of the patient and hypovolemic shock, being necessitating the transfusion of the patient...

We present a patient who developed black esophagus secondary to hypovolemic shock and was placed on total parenteral nutrition for three weeks after hospital discharge. The area of interest is the multimodal approach used in treatment of this noncompliant patient. Even with a high mortality rate, this case illustrates a successful outcome of a patient who responded to appropriate immediate therapy resulting in complete resolution of the necrosis with no further development of complications.

BACKGROUND: We have previously shown that treatment with valproic acid (VPA) decreases brain lesion size in swine models of traumatic brain injury (TBI) and controlled hemorrhage. To translate this treatment into clinical practice, validation of drug efficacy and evaluation of pharmacologic properties in clinically realistic models of injury are necessary. In this study, we evaluate neurologic outcomes and perform pharmacokinetic analysis of a single dose of VPA in swine subjected to TBI, hemorrhagic shock, and visceral hemorrhage...

Uterine fibroids in pregnancy present with numerous complications. However, spontaneous rupture is a rare and potentially life-threatening event. We report a case of a 43-year-old multiparous woman who presented with hypovolemic shock secondary to a ruptured uterine fibroid 2 days after a spontaneous vaginal delivery. Emergency laparotomy confirmed massive intra-abdominal hemorrhage from the ruptured capsule of a 10-cm subserosal fibroid. A myomectomy was performed. Her postoperative recovery period was uneventful...

Background: Dengue can cause increased vascular permeability that may lead to hypovolemic shock. Endothelial dysfunction may underlie this; however the association of endothelial nitric oxide pathways with disease severity is unknown. Methods: We performed a prospective observational study in two Vietnamese hospitals, assessing patients presenting early (<72 hours fever) and patients hospitalized with warning signs or severe dengue. The reactive hyperaemic index (RHI), which measures endothelium-dependent vasodilation and is a surrogate marker of endothelial function and NO bioavailability was evaluated using peripheral artery tonometry (EndoPAT) and plasma levels of L-arginine, Arginase-1 and ADMA were measured at serial time-points...

OBJECTIVE: Systemic capillary-leak syndrome is a very rare cause of recurrent hypovolemic shock. Few data are available on its clinical manifestations, laboratory findings, and outcomes of those patients requiring ICU admission. This study was undertaken to describe the clinical pictures and ICU management of severe systemic capillary-leak syndrome episodes. DESIGN, SETTING, PATIENTS: This multicenter retrospective analysis concerned patients entered in the European Clarkson's disease (EurêClark) Registry and admitted to ICUs between May 1992 and February 2016...

Acute hemorrhagic hypovolemic shock is caused by a significant high blood loss and leads to hemodynamic instability. The decrease in intravascular volume results in cellular hypoxia and finally in damage to organs such as the liver and the kidney. The liver plays a decisive role in the development or prevention of multiple organ failure after hemorrhagic shock. Despite the large number of experimental studies, the knowledge of pathophysiological mechanisms in the liver after hemorrhagic shock is incomplete...

Hemoperitoneum with hypovolemic shock from avulsion of a pedunculated leiomyoma is a rare but highly fatal condition that can occur spontaneously or as a result of trauma. We report a case of hemoperitoneum and hypovolemic shock secondary to a bleeding leiomyoma detected via computed tomography (CT) scan in a 39 year old premenopausal, gravida 0 female that presented with abdominal pain and became hemodynamically unstable in the emergency department. A preoperative bimanual exam revealed a mass consistent with a 20 week gestational uterus...

Spontaneous ruptures of the inferior vena cava (IVC) are rare. The mortality rate is high associated with all IVC injuries despite prompt resuscitation or operation. We present a case of 68-year-old women with spontaneous IVC dissection, presented as acute chest pain. Chest CT demonstrated a large amount of hemopericardium, and dilated inferior vena cava (IVC), suggesting cardiac tampon. Subsequently, hypovolemic shock and cardiac arrest occurred. After resuscitation, abdomen CT angiography was taken to find bleeding focus...

PURPOSE OF REVIEW: A discussion of recent research exploring the feasibility of perfusion-guided resuscitation of acute circulatory failure with a focus on lactate and microcirculation. RECENT FINDINGS: Upon diagnosis of shock, hyperlactemia is associated with poor outcome and, under appropriate clinical circumstances, may reflect inadequate tissue perfusion. Persistent hyperlactemia despite resuscitation is even more strongly correlated with morbidity and mortality...

The differential diagnosis of acute abdominal pain in pregnancy is broad and can be complicated by atypical manifestations that are due to the anatomic distortions and physiologic changes of pregnancy. Due to the lack of clinical understanding, angular pregnancy does not appear to be recognized as a clinical entity and many cases are likely to go undiagnosed. This is a case report of a 34-year-old woman who was referred to the obstetrics emergency department with sudden abdominal pain and in a state of hypovolemic shock...

Total gastric necrosis is a rare disease and easy to misdiagnose. Here we report a rare case of total gastric necrosis. The patient, an 89-year-old male, had epigastric pain for 5 days. He was transferred to our hospital because of intraperitoneal hemorrhage and hypovolemic shock. We performed an emergency laparotomy. During the surgery, we found a total of 3500ml unclotted blood in the abdomen, splenic infarction and gastric necrosis. Total gastrectomy with Roux-en-Y esophagojejunostromy and splenectomy was performed...

BACKGROUND: The aim of this case series is to describe the experience of using the non-pneumatic anti-shock garment (NASG) in the management of severe Postpartum hemorrhage (PPH) and shock, and the value of implementing this concept in high-complexity obstetric hospitals. METHODS: Descriptive case series of 77 women that received NASG in the management of PPH with severe hypovolemic shock from June 2014 to December 2015. Vital signs, shock index (SI), the lactic acid value and the base deficit were compared before and after NASG application...

The microcirculation is responsible for blood flow regulation and red blood cell distribution throughout individual organs. Patients with circulatory shock have acute failure of the cardiovascular system in which there is insufficient delivery of oxygen to meet metabolic tissue requirements. All subtypes of shock pathophysiology have a hypovolemic component. Fluid resuscitation guided by systemic hemodynamic end points is a common intervention. Evidence shows that microcirculatory shock persists even after optimization of macrocirculatory hemodynamics...

BACKGROUND: Surfing is an increasingly popular activity and surfing-related injuries have increased accordingly. However, to the best of our knowledge, there are no reports of penetrating upper airway injuries in surfers. We present a "cannot ventilate, cannot intubate" situation following penetrating neck injury by a surfboard fin. CASE PRESENTATION: A previously healthy 29-year-old Japanese man was swept off his board by a large wave and his left mandible, tongue root, and right epipharynx were penetrated by the surfboard fin...

INTRODUCTION: Cirrhosis of the liver is known for its high risk of mortality associated with episodes of acute decompensation. There is an even greater risk in patients that present with acute-on-chronic liver failure. The identification of patients at higher risk for adverse outcomes can aid in making the clinical decisions that will improve the prognosis for these patients. AIMS: To determine in-hospital mortality and evaluate the epidemiologic and clinical characteristics of patients with cirrhosis of the liver seen at a tertiary referral hospital...

BACKGROUND: Chemotherapy is considered the most appropriate treatment for metastatic uterine sarcoma, despite its limited efficacy. No other treatment has been conclusively proved to be a real alternative, but some reports suggest that anti-hormonal therapy could be active in a small subset of patients. We report the case of a patient with metastatic uterine carcinosarcoma with positive hormonal receptors and a complete pathological response. CASE PRESENTATION: A 54-year-old white woman presented to our emergency room with hypovolemic shock and serious vaginal bleeding...

RATIONALE: Aorto-esophageal fistula (AEF), a postoperative complication of esophagectomy, constitutes a very small percentage of all cases presenting with AEF; however, it is associated with a high mortality rate. Acute massive hemorrhage is the single largest cause of death in patients developing AEF. There is a lack of consensus on the optimal treatment of AEF. PATIENT CONCERNS: We present 3 cases secondary to esophagectomy due to lower thoracic esophageal carcinoma...

Background. Liver ischemia-reperfusion (IR) injury is one of the chief etiologies of tissue damage during liver transplantation, hypovolemic shock, and so forth. This study aimed to evaluate hepatoprotective effect of crocin on IR injury and on microRNAs (miR-122 and miR-34a) expression. Materials and Methods. 32 rats were randomly divided into four groups: sham, IR, crocin pretreatment (Cr), and crocin pretreatment + IR (Cr + IR) groups. In sham and Cr groups, animals were given normal saline (N/S) and Cr (200 mg/Kg) for 7 consecutive days, respectively, and laparotomy without inducing IR was done...
