Hereditary protein S deficiency (HSPD) is a predisposing factor to recurrent venous thrombosis but is not currently associated with stroke. We report two cases of HSPD revealed by stroke in young adults. The first one was a 36-year-old patient whith a pure motor hemiplegia, who gradually recovered without sequelae. Total and free protein S was decreased (55 and 10%). One of his brothers died from pulmonary embolism at 20 years and a sister had low protein S level without clinical signs. The second case was a 26-year-old patient who had a right hemiplegia with aphasia due to an infarction in middle cerebral artery area. He partially recovered, but the course of the illness was complicated by deep venous thrombosis of the lower limbs and pulmonary embolism. Total and free serum protein S level was severely decreased (25 and 0%). The patient's mother and one of his sisters also had low protein S but never had clinical complications. In both case, dupplex scanning, transcranial doppler, echocardiography, serum antithrombin III and protein C were normal. Cigarette smoking was the only risk factor for arterial disease. These two cases suggest that HSPD must be investigated in young patients with stroke, even in cases of lacunar stroke.

Our objective was to investigate possible factors implicated in either early death from or scintigraphic resolution of pulmonary embolism. To that end we conducted a retrospective study of 116 patients with either a high likelihood of pulmonary thromboembolism (PTE) diagnosed by scintiscan or with a fair probability of PTE by scintiscan accompanied by a positive phlebograph. The images were taken upon admission, at 7 days, 10 days and 6 months. The factors analyzed were age, sex, trauma, immobility, surgery, obesity, hemiplegia, venous insufficiency, cardiopulmonary disease, neoplasia, chest X-ray and ECG alterations, D(A-a)O2 and size of perfusion defects upon admission and 7 to 10 days later. We performed single-variable analyses and multiple logical regression analyses using perfusion defect at 6 months as the dependent variable. The early mortality rate (13%) was higher in patients with neoplasms, a larger alveolar-arterial index and greater perfusion defects upon admission. Scintiscans became normal in 28%. Multivariate analysis to predict total or partial resolution at 6 months showed that size of perfusion defects at 7 to 10 days was the best predictive factor. A cutoff point was calculated by analyzing the ROC for this factor. Thus, when the defect at 7 to 10 days was equal to or greater than 1 segment, the probability of residual defects remaining after 6 months was twice as great (sensitivity 83%, specificity 57%). In conclusion, early death was more likely in PTE patients with neoplasms, larger defects upon admission and greater alveolar-arterial difference. Scintigrams showed resolution 6 months after admission in 28%. The size of perfusion defects 7 to 10 days after admission was the factor that best predicted total of partial resolution at 6 months.

The case of a patient affected with acute pulmonary embolism and concomitant cerebral thromboembolism is described. The patient was admitted to our Coronary Care Unit with aphasia and hemiplegia. Five days before, he had undergone a hip replacement. A lung scan showed bilateral embolism; transthoracic echocardiogram revealed signs of pulmonary hypertension and the presence of a large, elongated, highly mobile "in-transit" thrombus entrapped into a patent foramen ovalis, and prolapsing into the right and left ventricle during diastole. The patient underwent surgical removal of the thrombus, with closure of the patent foramen. We did not treat the patient with thrombolysis, fearing the damage that a new embolism might produce. After surgery, the patient had a lengthy hospital stay because of renal failure and infection due to Pseudomonas aeruginosa. The patient was discharged from the hospital three months later on dialytic treatment and although he was still aphasic, there was partial recovery of motor function. Nevertheless, normalization of renal function and regression of aphasia occurred during the following months, with a residual mild motor defect of the right hand. This case report represents a starting point for discussing treatment of "in-transit" thrombi during pulmonary embolism.

Patients on warfarin are at high risk for potentially life-threatening hemorrhage even after relatively minor trauma. Outcomes of these patients and the potential complications of reversing the effects of anticoagulation have received little attention. This study was performed to determine the overall outcome of orally anticoagulated patients who sustained injury as well as to determine any untoward effects of reversing their anticoagulated states. A retrospective study of injured patients on warfarin was conducted on patients admitted to an urban, university, tertiary-referral, level I trauma center between 1/1/93 and 12/31/96. Surviving patients were followed for a period of at least 1 month. Injuries were grouped by anatomic site. Charts were reviewed for degree of anticoagulation on admission (ie, initial international normalized ratio [INR]), survival, adverse effects of reversal of anticoagulation, and reinstitution of warfarin therapy. Discharged patients were contacted at home for follow-up. Thirty-five consecutive patients, 18 men and 17 women, on warfarin therapy at the time of their injuries were reviewed. The mean age was 75 years, with a range of 39 to 96. The mean follow-up period was 12.7 months. Reasons for anticoagulation included atrial fibrillation, prosthetic heart valves, revascularized limb, hypercoagulable state, deep venous thrombosis, pulmonary embolism, phlebitis, and aortic stenosis. Mean admission INR was 3.2, with a range of 1.6 to 10.0. There were 8 in-hospital deaths. Intracranial hemorrhages accounted for the majority of injuries. Ten patients were not given reversal therapy. Four complications were attributable to reversal therapy (upper extremity hemiplegia, transient ischemic attack, deep venous thrombosis, arterial thrombosis). Twenty-one patients had their warfarin reinstituted. Follow-up of surviving patients ranged from 1.5 to 42 months. Patients on warfarin are at high risk for intracranial hemorrhage following trauma. Patients on warfarin may be reversed during the acute period following injury, but transient complications may arise. Further prospective studies need to be conducted to determine which anticoagulated trauma patients may not require reversal therapy.

Etiologies of shoulder pain in the hemiplegic population, such as glenohumeral subluxation, frozen shoulder, and reflex sympathetic dystrophy (RSD), have been described extensively. We present an 89-year-old woman with right hemiparesis secondary to ischemic lacunar infarction who developed sudden onset of right shoulder pain on the fifth day of inpatient rehabilitation. The pain was severe, limiting range of motion (ROM) and participation in therapy. Extensive investigations to rule out subluxation, fracture, connective tissue disease, RSD, and pulmonary embolism were negative. Ultimately, her shoulder pain and decreased ROM completely resolved with antibiotic treatment for right lower lobe pneumonia. We conclude that her symptoms were possibly referred pain from diaphragmatic irritation transmitted via right C4 sensory axons in the phrenic nerve, which shares the same dermatome as the right acromion area. This case was an unusual presentation of pneumonia in an elderly woman with hemiplegia. We recommend that pneumonia be considered in the differential diagnoses of shoulder pain.

A 56-year-old woman with right hemiplegia for recent cerebral bleeding suddenly complained of dyspnea and chest pain with hypoxia during rehabilitation. Eight days after this first attack, she suffered prolonged right heart failure and hypoxia due to recurrent pulmonary embolism. Arterial blood gas analysis of room air showed 34.5 mmHg of PaO2 and 29.2 mmHg of PaCO2. Echocardiography showed enlargement of the right atrium and ventricle with pulmonary hypertension. Enhanced chest computed tomography revealed pulmonary emboli from the main pulmonary artery to the periphery. Despite intensive treatment, heart failure and hypoxia did not improve. We conducted pulmonary embolectomy under cardiopulmonary bypass requiring percutaneous cardiopulmonary bypass support for 2 days due to right heart failure. She is currently doing well in the 9 months following surgery.

Venous thromboembolism (VTE) is a common complication after acute ischemic stroke. When screened by 125I fibrinogen scanning or venography, the incidence of deep-vein thrombosis (DVT) in stroke patients is comparable with that seen in patients undergoing hip or knee replacement. Most stroke patients have multiple risk factors for VTE, like advanced age, low Barthel Index severity score or hemiplegia. As pulmonary embolism is a major cause of death after acute stroke, the prevention of this complication is of crucial importance. Prospective trials have shown that both unfractionated heparin (UFH) and low molecular weight heparin (LMWH) are effective in reducing DVT and pulmonary embolism in stroke patients. Current guidelines recommend the use of these agents in stroke patients with risk factors for VTE. Some clinicians are concerned that the rate of intracranial bleeding associated with thromboprophylaxis may outweigh the benefit of prevention of VTE. Low-dose LMWH and UFH seem, however, safe in stroke patients. Higher doses clearly increase the risk of cerebral bleeding and should be avoided for prophylactic use. Both aspirin and mechanical prophylaxis are suboptimal to prevent VTE. Graduated compression stockings should be reserved to patients with a clear contraindication to antithrombotic agents.

This review identifies the current literature on the use of bevacizumab for cerebral radiation necrosis in patients with high-grade gliomas, summarizes the clinical course and complications following bevacizumab, and discusses the relative costs and benefits of this therapeutic option. A Medline search was conducted of all clinical studies before September 2012 investigating outcomes following use of bevacizumab therapy for radiation necrosis in patients with high-grade gliomas. Clinical and radiographic outcomes are reviewed. Seven studies reported a total of 30 patients with high-grade gliomas treated with bevacizumab for radiation necrosis. All patients demonstrated decreased radiographic volume of edema on T1 and T2 MRI sequences. Clinical outcomes were reported for 23 patients: 16 (70 %) had improvement in neurologic signs or symptoms, 5 (22 %) had mixed results, and 2 (9 %) remained neurologically unchanged. Complications were documented in 5 of 7 studies (18 of 29 patients, 62 %) and included deep vein thrombosis, pulmonary embolism, visual field worsening, worsening hemiplegia, pneumonia, seizure, and fatigue. Only one study evaluated quality of life measures and none evaluated cost or cost effectiveness. Data regarding the use of bevacizumab to treat radiation necrosis in patients with high-grade gliomas is limited and primarily class III evidence. While bevacizumab improves neurological symptoms and reduces radiographic volume of necrosis-associated cerebral edema, it comes at the expense of a high rate of potentially serious complications. Definitive evidence for the utility, cost-effectiveness, and overall efficacy of this management strategy is currently lacking and additional investigation is warranted.

Trousseau's syndrome, a complex paraneoplastic disease, is characterized by the occurrence of thromboembolic disorders such as brain infarctions in patients with malignant neoplasms. We report the case of a 46-year-old woman with ovarian cancer who had suffered cerebral infarctions and presented with left hemiplegia, aphasia, and atypical genital bleeding. She suffered multiple right brain infarctions, a pulmonary embolism, a right renal infarction with bilateral hydronephrosis and deep venous thromboses and exhibited increased D-dimer and fibrinogen levels and so was administered heparin (10,000 U x day(-1)). She had no other underlying diseases such as coagulopathy, cardiovascular disease, collagen disease, or angiitis. Therefore, we were able to diagnose her with Trousseau's syndrome. She was scheduled to undergo total abdominal hysterectomy with bilateral oophorectomy, pelvic lymphadenectomies, and omentectomy. Preoperatively, an inferior vena cava filter was temporarily installed to prevent the development of further pulmonary thromboses. General anesthesia was uneventfully maintained by inhalation of oxygen, air, and sevoflurane and the continuous infusion of remifentanil whilst regional cerebral oxygen saturation and transesophageal echocardiography monitoring were performed. Postoperatively, she received heparin-based anticoagulant therapy (10,000 U x day(-1)) and did not exhibit bleeding diathesis or thrombosis. It is of great importance that anesthesiologists are aware of the thromboembolic status of patients with malignant neoplasms, especially those with gynecological tumors.

We report a case of paradoxical cerebral embolism in a 63-year-old man with newly diagnosed rectal cancer. The onset was heralded by nearly simultaneous pulmonary embolism and left hemiplegia. He was subsequently found to have deep venous thrombosis. Despite placement of a vena caval filter, a second cerebral infarction occurred in the opposite hemisphere. Air contrast transthoracic echocardiography was negative, but autopsy revealed a patent foramen ovale. Problems in the identification of paradoxical embolism are discussed.
