Because of its wide range of presentations, its highly variable mode of onset, its numerous causes, and its unpredictable outcome, cerebral venous thrombosis (CVT) remains a diagnostic and therapeutic challenge. Treatment of CVT consists primarily of symptomatic treatment of seizures and intracranial hypertension, antithrombotics, and etiologic treatment whenever possible. Heparin remains the first line of treatment for CVT; although its systematic use remains debated, recent studies have confirmed its safety even in patients with large hemorrhagic infarctions. The addition of local thrombolysis is indicated for patients with clinical worsening related to extension of the venous thrombosis, despite adequate anticoagulation and optimal symptomatic and etiologic treatment. In contrast to arterial stroke, complete recovery of prolonged or severe neurologic deficit is possible, justifying initiation of anticoagulation and eventually thrombolysis, even when the clinical situation seems desperate. New techniques using mechanical devices disrupting the clot may be used in addition to thrombolysis in rare cases. Ventricular drainage is indicated in cases of cerebellar infarction or deep venous thrombosis associated with hydrocephalus. Decompressive craniotomy may be performed acutely in patients with untractable intracranial hypertension and herniation.

Left atrial myxoma is a benign tumor but it has a high prevalence of important complications. We report a case of a 73-year-old man affected by hypertension and chronic atrial fibrillation admitted to our hospital for pulmonary embolism, that resulted associated with a proximal deep venous thrombosis of the right leg and with an unknown left atrial myxoma.

A 50-year-old man with hypertension presents with a 2-day history of right calf swelling and pain. Venous duplex ultrasound reveals a right soleal vein thrombosis. He denies history of bleeding, renal disease, and symptoms suggestive of pulmonary embolism (PE). Physical examination is unrevealing except for calf tenderness, redness, warmth, and swelling. He is ambulatory. A decision is made to treat the calf deep venous thrombosis (DVT) with anticoagulation.

A 62-year-old man with a past medical history notable for hypertension, osteoarthritis, and calf deep vein thrombosis at age 55 following a total hip arthroplasty presents to the emergency department with acute-onset dyspnea and right-sided pleuritic chest pains. His medications consist of a calcium channel blocker and a COX-2 inhibitor. Pretest clinical suspicion for pulmonary embolism (PE) is high. Ventilation and perfusion lung scintigraphy are interpreted as being high-probability for PE. The nurse asks if a stat transthoracic echocardiogram should be ordered.

Both neurologic and medical complications influence outcome after stroke. Space-occupying supratentorial infarcts can cause transtentorial or uncal herniation, which leads to death. Treatments aimed at reducing intracranial pressure in patients with such infarcts are of unproven value. Mass-producing cerebellar infarction may lead to brainstem compression and obstructive hydrocephalus. These lesions often are treated surgically. Although anticonvulsants are not indicated for prophylaxis, the occurrence of epileptic seizures mandates treatment to prevent recurrences. Depression is common in the acute stage of stroke, but is probably not more prevalent after stroke than after myocardial infarction. Although dysphagia is common, it usually is a transient problem. Patients with a decrease of consciousness or brainstem dysfunction usually need tube feeding for a certain period of time. Medical complications, such as fever, infections, hyperglycemia, cardiac disorders, pressure sores, and deep venous thrombosis, are associated with a poor prognosis and should be treated as early as possible. Measures to prevent these complications are part of general care. Hypertension is very common during the week after stroke and should be treated only in case of extremely high values or malignant hypertension. A multidisciplinary approach in the stroke unit is necessary to prevent and manage complications in the acute phase of stroke.

We describe a 30-year-old male who presented with acute onset of breathlessness, tachycardia, and palpitations associated with distension of jugular vein and clear lungs on physical examination. The chest X-ray was normal and ECG was showing S1Q3T3 and right ventricular strain pattern. His 2-D echocardiography was showing dilated right atrium, right ventricular dilatation and moderate pulmonary arterial hypertension. He was found to have thrombosis involving left side of deep venous system with normal superficial venous system (Doppler proved). All routine blood investigations for etiology of recurrent DVT were normal except serum homocyteine level, which was significantly raised. Megaloblastic anemia on peripheral smear and hyperhomocysteinemia prompted us to search for its cause, which was subsequently found to be vitamin B12 deficiency. Such an association of megaloblastic anemia due to vitamin B12 deficiency leading to hyperhomocysteinemia and subsequent thrombosis in left venous system presenting as acute pulmonary embolism has not been described earlier in the medical literature.

We enrolled 5,451 patients with ultrasound-confirmed deep vein thrombosis (DVT), including 2,892 women and 2,559 men, from 183 United States sites in our prospective registry. The 5 most frequent co-morbidities were hypertension (50%), surgery within 3 months (38%), immobility within 30 days (34%), cancer (32%), and obesity (27%). Of the 2,726 patients who had their DVT diagnosed while in the hospital, only 1,147 (42%) received prophylaxis within 30 days before diagnosis.

The real incidence of the post-thrombotic syndrome (PTS) is not known precisely, though of the most part of the variable studies, seems be deduced that it can be established a year after the deep venous thrombosis (DVT) acute of the inferior members in 17% to the 50% of the patients. Inseparably united to the venous hypertension that continues to the development of the incompetence valvular, is accompanied of a series of inflammatory reactions that include the increase in the permeability endothelial, the union of the circulating leukocytes at endothelium, the infiltration by monocytes, lymphocytes and mastocytes of the connective tissue, and the development of infiltrated tissular fibrotics and different molecular markers. To the contrary that in the DVT, we know very little about the factors that increase the risk of suffering a PTS, since the only one identified up until now it is the recurrent DVT. Currently we have different scales standardized for their your clinical diagnosis, though the Echo-Doppler is, currently, the technique not invasive of election to detect, locate and evaluate the venous disability valvular and the venous obstruction chronicle. The modern technical of image: computed tomography (CT), magnetic resonance (MR) and isotopics have a promising future, even though are found in validation phase. The phlebothropics drugs are the therapeutic election strategy for the patients with PTS in those which is not indicated the surgery or in those which this is a assisting of the medical treatment. Finally, the deep venous surgery must be reserved for all those patients that suffer from venous insufficiency serious chronicle, with meaningful venous reflux and ambulatory venous hypertension.

As for many cardiovascular events, pulmonary embolism (PE) is not randomly distributed over time, but shows rhythmic patterns. The purpose of this study was to investigate whether such temporal pattern of occurrence varied in subgroups of patients according to different risk comorbid conditions. All cases of PE observed at the Hospital of Ferrara, Italy, from 1998 to 2001, were considered. After determination of the day of onset, the population was grouped by gender and the most common underlying risk comorbid conditions, e.g., deep vein thrombosis (DVT), neoplasms, cardiomyopathies, traumas/surgical operations, diabetes mellitus, pulmonary diseases, hypertension, cerebrovascular diseases, heart failure, hematologic diseases. For statistical analysis, chi-square test for goodness of fit and partial Fourier series were used. A total of 784 cases (mean age 71 +/- 14 years) were included. Frequency of onset was higher in winter for total population (p = 0.002), men (p = 0.004), DVT (p = 0.001), pulmonary disease (p = 0.008), cardiomyopathies (p = 0.011), and major traumas/surgical operations (p = 0.049). Chronobiologic analysis identified a winter peak for total population (p = 0.008), men (p < 0.001), DVT (p = 0.006), pulmonary diseases (p = 0.017), and hypertension (p = 0.026). This study confirms the winter peak of PE and provides evidence that it is not influenced by the underlying clinical conditions, but probably by endogenous variations.
