    Sinus thrombosis has rarely been associated with closed head injury; more often, thrombosis of the sigmoid or transverse sinus is caused by otogenic inflammations or tumours, or occurs during pregnancy. Symptoms are frequently vague, while untreated thrombus progression may be fatal due to venous congestion and infarction. We report a 32-year-old man presenting with right hearing loss, tinnitus and headache 2 days after a closed head injury. Neurological examination showed no additional abnormality. The EEG showed focal bifrontal slowing. CT revealed a fracture of the occipital bone. MRI and MRA demonstrated complete thrombosis of the right sigmoid and transverse sinuses. After 2 weeks of intravenous heparin therapy followed by warfarin, the patient's hearing improved and MRI and MRA showed complete recanalisation of the sigmoid and transverse sinuses. Venous sinus thrombosis can be an undetected sequel to head injury. Appropriate imaging studies should be carried out to enable therapy to be started as soon as possible. (orig.)

    Full Text Available Cerebral venous sinus thrombosis is an uncommon cause of stroke presenting with varied presentation patterns. We report a case of a 21-year-old woman with superior sagittal sinus (SSS thrombosis (SSST developing after childbirth, presenting with visual hallucinations, severe headache, and tonic-clonic seizures. Time-of-flight magnetic resonance angiography (TOF-MRA demonstrated the presence of thrombus in SSS. She was treated with low molecular weight heparin (LMWH followed by warfarin. She had excellent recovery a few weeks after admission and was regularly followed up. Although this condition can be presented with different neurological symptoms, it does not typically present with hallucinations. We suggest that CSVT should be suspected even when a patient presents with an atypical picture in a category of patients at higher risk.

    OBJECTIVE There are no guidelines for the management of postoperative lateral sinus thrombosis following posterior fossa surgery. Introducing treatment-dose anticoagulant therapy during the immediate postoperative period increases the risk of intracranial bleeding. This study assessed the incidence of and risk factors associated with postoperative lateral sinus thrombosis and the complications related to thrombosis and/or anticoagulation. METHODS This study was a retrospective monocentric analysis of adult patients who underwent surgical removal of a posterior fossa space-occupying lesion with available postoperative imaging. Postoperative lateral sinus thrombosis was defined as a T2 * hypointensity within the venous sinus and/or a filling defect on postcontrast MRI or CT scan. RESULTS Among 180 patients, 12 (6.7%; 95% CI 3.0-10.4) were found to have lateral sinus thrombosis on postoperative imaging, none of whom were symptomatic. Unadjusted risk factors for postoperative lateral sinus thrombosis were a history of deep venous thrombosis (p = 0.016), oral contraceptive pill (p = 0.004), midline surgical approach (p = 0.035), and surgical exposure of the sinus (p < 0.001). Seven of the patients (58.3%) with a postoperative lateral sinus thrombosis received immediate treatment-dose anticoagulant therapy. Lateral sinus recanalization occurred radiologically at a mean time of 272 ± 23 days in 85.7% of patients (6 of 7) undergoing treatment-dose anticoagulant therapy and in 20% of patients (1 of 5) not receiving treatment-dose anticoagulant therapy. Postoperative complications occurred in 56.2% of patients (9 of 16) who received treatment-dose curative anticoagulant therapy and in 27% of patients (45 of 164) who did not. CONCLUSIONS Incidental radiological lateral sinus thrombosis following posterior fossa surgery has an incidence of 6.7%. To further define the benefit-to-risk ratio of a treatment-dose anticoagulant therapy, a prospective trial should be considered.

    To exmaine the distribution of age, gender, time between onset and presentation, clinical findings, predisposing factors, platelet distribution width, mean platelet volume values and neuroimaging findings, together with the treatment regime and the outcome for patients of cerebral venous sinus thrombosis. Methods: The retrospective, descriptive cross-sectional study was conducted at Yuzuncu Yil University, Medical Faculty Hospital in Van, Turkey, comprising 51 cases diagnosed with cerebral venous sinus thrombosis between January 2008 and September 2011. The diagnosis was based on the results of clinical evaluation, cranial magnetic resonance imaging and venography. SPSS 16 was used for statistical analysis. Results: Overall, 43 (84.3%) of the cases were female, and 8 (15.7%) were male. The average age was 32+-11.13 years. The most frequent symptom was headache in 41 (80.4%) cases. The postpartum period was one of the most observed predisposing factors in 17 (33.3%) patients. The magnetic resonance imaging was normal in 35 (68.6%) cases, but in all of the cases, magnetic resonance venography was abnormal. Topographically, the most frequent involvement was transverse sinus in 40 (78.4%) cases. Besides, 50 (98%) patients were discharged following full recovery or mild sequela and only 1 (2%) case had severe sequela. Conclusion: Patients presenting with headache should be examined carefully in the emergency department. Early diagnosis and treatment with clinical and neuroimaging techniques for such patients is recommended. (author)

    Full Text Available Cerebral venous sinus thrombosis (CVST is an uncommon, life-threatening condition with a variable clinical presentation that makes it a challenge of diagnosis. A 39-year-old male patient presented to the hospital with complete loss of conscious and admitted to Medical Intensive Care Unit for investigation without any obvious history that was difficult for diagnosis. In this case, the patient presented with coma that is a rare presentation of CVST with no obvious clinical history and he was male patient that means he is free of all gender-specific risk factors of CVST. The brain computed tomography (CT scan showed hypodense lesion in the left upper parietal region with no hemorrhage. The lesion was low-signal intensity (SI on T1WIs and high SI on T2WIs and restricted on diffusion-weighted images like arterial infarctions, but magnetic resonance angiography (MRA was normal that excluded arterial infarction. Gadolinium-enhanced MR venography (MRV showed the filling defect of CVST. CVST can be present by a mysterious clinical presentation that makes it as a challenge of diagnosis even by medical imaging by CT and MR imaging (MRI. A combination of MRI and MRV is the best, noninvasive, and nonionizing imaging modality for the diagnosis of CVST.

    Full Text Available Abstract Background To recognize ocular presentations in cranial venous sinus thrombosis (CVST which were easy to be misdiagnosis. Design Retrospective study. Methods Review clinical informations including general informations, general performances, and ocular presentations of 118 inpatients with CVST in the general hospital of chinese people's liberation army during 2005-2009. Main Outcome Measures The ocular symptoms as the initial onset presentations or simultaneous phenomenon among different onset type patients were analyzed. Results Of all the CVST patients, 21.2% (25/118 presented with ocular symptom as the initial presentation, 30.5% (36/118 presented with ocular symptom as well as the other symptoms, and 48.3% (57/118 presented with non-ocular symptoms as the initial onset. The CVST patients were divided into 3 groups according to the onset type. There was no marked statistical significance among groups. The most common major complaints were blurring and degeneration of acute vision, accounting for 85.9% (61/71 of all abnormal ocular chief complaints. The most common objective sign in eyes was papilloedema, accounting for 48.3% (57/118 in this group of CVST patients. About 22.4% (13/58 showed acute vision deterioration at 1-year follow-up, due to optic atrophy. Conclusions As ophthalmologists, we should master the onset characteristics and clinical manifestations of CVST. Early diagnosis and treatment is very important for the prevention of vision deterioration, especially for patients with ocular syndrome as the initial onset syndrome. For isolated agnogenic intracranial hypertension, we should consider the possibility of CVST.

    Full Text Available Necrotizing fasciitis is a rapidly progressive life threatening bacterial infection of the skin, the subcutaneous tissue, and the fascia. We present a case of necrotizing fasciitis involving the nose complicated by cavernous sinus thrombosis. Few cases of septic cavernous sinus thrombosis have been reported to be caused by cellulitis of the face but necrotizing fasciitis of the nose is rare. It is very important to recognize the early signs of cavernous thrombosis. Treatment for septic cavernous sinus thrombosis is controversial but early use of empirical antibiotics is imperative.

    Full Text Available Thrombosis of the intracranial dural sinuses and internal jugular veins may occur as a complication of head and neck infections, surgery, central venous access, local malignancy, polycythemia, hyperhomocysteinemia, neck massage and intravenous drug abuse. A high degree of clinical suspicion followed by adequate imaging is prerequisite to early diagnosis and management. We report a young man who had dural sinus thrombosis with jugular venous thrombosis following neck massage.

    Full Text Available In the majority of patients with raised intracranial pressure, the papilledema is bilateral. Unilateral papilledema is rare in conditions causing intracranial hypertension, and it has been described in Foster–Kennedy syndrome and in some cases of idiopathic intracranial hypertension. It has never been reported in cerebral venous thrombosis. We report a young lady presenting with features of subacute onset of headache with seizures, on evaluation she had superior sagittal and bilateral lateral sinus thrombosis. The risk factors found on evaluation were Vitamin B12 deficiency and hyperhomocysteinemia. On optic fundus examination, she had swollen optic disc on the right side with normal fundus on the left side, confirmed with the orbital ultrasound B-scan and optic coherence tomography. Her magnetic resonance imaging showed features of raised intracranial pressure with thrombosis of the superior sagittal and bilateral lateral sinus thrombosis. She was treated with anticoagulation (heparin followed by oral anticoagulants, antiedema measures, and vitamin supplementation for hyperhomocysteinemia. She improved over time and was asymptomatic during follow-up. We discuss the possible mechanisms described in the literature for unilateral papilledema. This report highlights the need for carefully performing bilateral fundus examination so as not to miss the vision or life-threatening causes of a headache.

    2012-01-01

    Full Text Available Cerebral venous sinus (sinovenous thrombosis (CSVT is a rare life-threatening disorder in childhood that is often misdiagnosed. CSVT encompasses cavernous sinus thrombosis, lateral sinus thrombosis, and superior sagittal sinus thrombosis (SSST. We present an adolescent girl who was well until two weeks earlier when she had a throbbing frontal headache and fever with chills; she later had dyspnoea, jaundice, melena stool, multiple seizures, nuchal rigidity, and monoparesis of the right lower limb a day before admission. Urine test for Salmonella typhi Vi antigen was positive, and Widal reaction was significant. Serial cranial computerized tomography scans revealed an expanding hypodense lesion in the parafalcine region consistent with SSST or a parasagittal abscess. Inadvertent left parietal limited craniectomy confirmed SSST. She recovered completely with subsequent conservative management. Beyond neuropsychiatric complications of Typhoid fever, CSVT should be highly considered when focal neurologic deficits are present.

    To describe MR findings of cerebral venous sinus thrombosis. We reviewed 11 MR images of six patients with cerebral venous sinus thrombosis. The MR images were retrospectively analyzed in terms of location and signal intensity of the thrombi, parenchymal lesions such as hemorrhage and edema, and changes in follow up study obtained in 4 patients. The thrombus in venous sinus was visualized on MRI in all six patients. The most frequently involved sites were superior sagittal sinus(n=4) and left transverse sinus(n=4). Signal intensity of the thrombus was isointense or hyperintense on both T1- and T2-weighted images with loss of normal signal void of the sinus on all sequences in all patients. Parenchymal lesion was patients in five of six cases, manifested as local hemorrhage in three and edema in three cases(one case overlapped). Local edema seen in three patients was completely resolved on follow up study of seven to 29 days intervals. It is concluded that iso- or high signal intensity with loss of signal void in venous sinus is virtually diagnostic of venous sinus thrombosis. If there are local parenchymal lesions such as hemorrhage and/or edema of unknown causes, cerebral venous sinus thrombosis should be included in differential diagnosis.

    2016-01-01

    Perioperative straight sinus thrombosis is extremely rare. A 59-year-old female was admitted to our department because of incidentally found small anterior cerebral artery (A1) aneurysm with microbleeding. After clipping the cerebral aneurysm, she had delayed emergence from anesthesia, total aphasia, and right hemiparesis. Fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) of the head showed hyperintensity in the bilateral caudate nuclei, putamina, and thalami, and computed tomography of the head showed a hyperdense straight sinus, suggesting straight sinus thrombosis. Her neurologic symptoms improved gradually, and she achieved a full clinical recovery, with radiological evidence of recanalization of the straight sinus at follow-up. The possibility of straight sinus thrombosis should be considered in postoperative patients with unexplained postoperative deficits when MRI demonstrates hyperintensity in the bilateral basal ganglia and thalami on FLAIR signal images.

    To evaluate the MR findings of septic thrombosis of the cavernous sinus. Eleven MR images of six patients with septic cavernous sinus thrombosis obtained over a five-year period and proven clinically or radiologically were retrospectively reviewed. The contour and enhancement pattern of the cavernous sinus, changes in the internal carotid artery, orbit, pituitary gland and sphenoid sinus, and intracranial abnormalities were analyzed and compared with the findings of follow-up studies. In all six patients, contrast study revealed asymmetrical enlargement of the ipsilateral cavernous sinus and multiple irregular filling defects within it. Narrowing of the cavernous portion of the ipsilateral internal carotid artery was noted in five patients, upward displacement of the ipsilateral internal carotid artery in four, ipsilateral proptosis with engorgement of the superior ophthalmic vein in two, pituitary enlargement in five, and inflammatory change in the sphenoid sinus in six. Associated intracranial abnormalities included edema and enhancement in the meninx, temporal lobe, or pons adjacent to the cavernous sinus in four patients, hydrocephalus in one, and cerebral infarction in one. Follow-up MR imaging indicated that the extent of asymmetrical enlargement of the cavernous sinus, filling defects within it, as seen on contrast study, and enlarged pituitary glands had all decreased, without significant interval change. MR imaging is useful in the diagnosis of septic cavernous sinus thrombosis. Asymmetrical enlargement of the cavernous sinus, multiple irregular filling defect within it, as seen on contrast study, and changes in the internal carotid artery are characteristic findings.

    A case of transverse sinus thrombosis is described in an adolescent male with antecedent meningomyelocele corrected by surgery, and ventriclo-peritoneal derivation. Four months before the occurrence of thrombosis, he presented with bilateral otitis media and mastoiditis, and was treated with antibiotic. Magnetic resonance images were not obtained before referral to our hospital. The patient received full anticoagulation and his clinical course was uneventful. He remains asymptomatic under outpatient surveillance till this report. The aim of reporting the case is to emphasize the role of otologic infections in the origin of intracranial thrombotic phenomena, and highlights the findings of magnetic resonance venography for characterization of intracranial sinus thrombosis.

    Thrombosis of the sinuses is a distinct cerebrovascular disorder that, unlike arterial stroke, most often affects young adults and children. The symptoms and clinical course are highly variable. During the past decade, increased awareness of the diagnosis, improved neuro-imaging techniques, and more effective treatment have improved the prognosis. More than 80% of all patients now have a good neurologic outcome. This review summarizes recent insights into the pathogenesis of sinus thrombosis, risk factors, and clinical and radiological diagnosis and discusses the current evidence and controversies about the best treatment.

    Four adult patients were diagnosed as having dural sinus thrombosis (DST) by means of magnetic resonance (MR). In the three cases of acute thrombosis, MR disclosed diffuse or segmental hyperintensity in the sinuses involved, which persisted regardless of the sequence and orientation of the plane selected. MR angiography (MRA) provided diagnostic information that proved useful in the chronic case, as well as in the two cases in which follow-up was carried out to determine the degree to which permeability was restored to the sinuses involved. MR diagnosis of DST can produce false positives and negatives, the causes of which should be known, as well as the ways to avoid them, in order to prevent diagnostic errors. MR, when applied and interpreted correctly, can be considered the first, and in many cases the only, choice as a diagnostic method in DST. (Author)

    Objective: To evaluate the clinical efficacy and safety of endovascular treatment for intracranial venous sinus thrombosis. Methods: Ten patients with intracranial venous sinus thrombosis, confirmed by CT, MRI, MRV and / or DSA and encountered during the period of Aug. 2005-Aug. 2007, were treated with endovascular management after they failed to respond to anticoagulant therapy. Of ten patients, intravenous thrombolysis and mechanical thrombus maceration were carried out in 6, while intravenous thrombolysis, mechanical thrombus maceration together with intra-arterial thrombolysis were employed in 4. After the treatment, the anticoagulant therapy continued for 6 months. The patients were followed up for 12-29 months (mean 21 months). Results: After the treatment, the clinical symptoms and signs were completely or partially relieved in eight patients, including disappearance of headache (n=6) and relive of headache (n=2). No obvious improvement was found in one patient and linguistic function disturbance was seen in the remaining one. Lumbar puncture showed that the cerebrospinal fluid pressure returned to normal in all patients. Neither recurrence of thrombosis nor new symptom of neuralgic dysfunction was observed. No procedure-related intracranial or systemic hemorrhagic complications occurred both during and after the operation. Conclusion: Endovascular treatment is an effective and safe procedure for the potentially catastrophic intracranial venous thrombosis. (authors)

    Septic cavernous sinus thrombosis, a relatively uncommon disease entity, frequently can be fatal. Early diagnosis is imperative in order that appropriate treatment be instituted. A 59-year-old woman who was admitted to our institution with complaints of diplopia, blurred vision and fevers that developed following a tooth extraction is presented. Initial CT and lumbar puncture on the day of admission were totally normal. A repeat CT performed 48 hours after admission, on the same day as gallium imaging, demonstrated findings consistent with cavernous sinus thrombosis. Gallium imaging demonstrated intense uptake in the left cavernous sinus and left orbit as well as moderately increased activity in the right cavernous sinus and orbit, confirming infection. The patient was treated with antibiotics, and repeat CT and gallium imaging were performed ten days later, both of which demonstrated near total resolution of the disease process. Conceivably, if gallium imaging had been initiated on the day of admission it may have been the first study to demonstrate an infectious process in the cavernous sinus. Gallium imaging should be considered as a diagnostic tool in the noninvasive workup of this entity

    Headache represents up to 4% of all emergency department (ED) visits. Emergency physicians generally are concerned with identifying those patients whose headaches are caused by life-threatening conditions. Cerebral venous sinus thrombosis may be difficult to diagnose clinically because of its various and nonspecific manifestations. The most frequent but least specific symptom of sinus thrombosis is severe headache, which is present in more than 90% of adult patients. In the case report we present, a patient had severe headache and was diagnosed until third ED visit at different hospitals. He had one of the most unusual causes of headache, that is, cerebral venous sinus thrombosis due to hyperthyroidism.

    Full Text Available Background: Cerebral venous thrombosis (CVT is uncommon after cesarean section. Although it can be a leading cause of maternal mortality. CVT may occur during pregnancy because of hypercoagulable states such as preeclampsia, thrombophilias, antiphospholipid antibody syndrome and sepsis.Case presentation: A 31 years old woman G2 Ab1 at 37 weeks gestational age with  premature rupture of membrane underwent cesarean section because breech presentation and preeclampsia. Spinal anesthesia was done for emergent cesarean section. On the second day after cesarean section, she developed headache, vomiting, focal neurologic deficits, paresthesia, blurred vision. Brain magnetic resonance imaging (MRI showed thrombosis in anterior half of superior sagittal sinus. Treatment consisted of anticoagulation.  Conclusion: Thrombophilias, pregnancy-related hypertension and cesarean section are the predisposing factors for thromboembolism. Unfractionated heparin and low molecular weight heparin (LMWs are effective drugs for thromboprophylaxis. It is vital to prevent venous thrombosis to reduce mortality during both intrapartum and postpartum periods. Consideration of cerebral venous thrombosis in similar cases is recommended.

    Full Text Available The dural venous sinus thrombosis is a benign disease, representing about 1% of cerebral vascular events. In some cases the development of the disease increased intracranial pressure or symptomatic epilepsy. The development towards a dural venous sinus thrombosis is rare, but is a condition to be considered before the development of ischemic vascular events and a history of recent head trauma. Intracranial hematomas or skull fractures can lead to the establishment of obstructive pathology of the dural venous sinuses. The knowledge of this entity is necessary for the critical care staff and neurosurgery staff.

    Full Text Available Background: Cerebral venous-sinus thrombosis is an uncommon form but important cause of stroke, especially in young-aged women. Methods: We performed a retrospective descriptive-analytical study in which 124 patients with cerebral venous-sinus thrombosis, who referred to Nemazee Hospital, Shiraz University of Medical Sciences from January 2000 to March 2008, were included, and their demographic, etiologic, radiological and prognostic characteristics were evaluated. Results: The patients' mean age was 34.01±10.25. Eighty seven (70.16% were women and 37 (29.83% were men. The most frequent clinical manifestations were headache, papilledema and seizures. Fifty seven (65.51% women took oral contraceptive pills. Twenty of 57 women (35.08% took the pill longer than one month to be able to fast in Ramadan or perform the Hajj ceremonies. In the mean time they developed cerebral venous-sinus thrombosis. Superior sagital sinus, with or without lateral sinuses, was the most involved area (70.96%. High mortality and morbidity rates (14.51% and 35.48%, respectively were found in patients. Poor prognostic factors at the time of admission were stupor and coma (P=0.001 and evidence of hemorrhage in primary CT scan (P=0.005. Conclusion: Taking oral contraceptive pills was a main factor associated with cerebral venous-sinus thrombosis. Clinical manifestations, prognostic factors, common involved sinuses and image findings of this study were similar to those of other studies. Health care policy makers should design a plan to warn susceptible women of the risk of cerebral venous-sinus thrombosis, and to educate them the ways to prevent it

    Sinus pericranii is an abnormal venous communication between the intracranial dural sinuses and epicranial venous dilatations. The periorbital location is uncommon; spontaneous partial thromboses of the subcutaneous varices have been reported in association with local signs and symptoms; however, to our knowledge there are no reports of sinus pericranii associated to thrombosis in the ophthalmic vein. Sinus pericranii is related to arteriovenous and lymphatic-venous malformations. We present the case of a patient with a generalized and diffuse disorder of venous drainage that affected the right cerebral hemisphere who presented at the emergency department with ophthalmologic signs and symptoms after thrombosis of the superior ophthalmic vein and who had three sinus pericranii located in the frontal, parietal, and occipital areas.

    Various hypotheses have been reported concerning the pathogenesis of dural arteriovenous fistulas (DAVFs). However, it is still controversial whether sinus thrombosis or venous hypertension has a greater influence on the formation of DAVFs. We present a rare case of multiple DAVFs that developed after sinus thrombosis. Chronic venous hypertension secondary to sinus thrombosis in the left transverse-sigmoid sinus induced the multiple DAVFs, including one in the right cavernous sinus, which was remote from the occluded sinus. This case indicates the importance of venous hypertension in the formation of DAVFs. (orig.)

    A 50-year-old woman with idiopathic deep cerebral sinus and vein thrombosis (DCVT) had cerebellar disturbance prior to impaired consciousness. CT and MRI revealed haemorrhagic infarction in the cerebellum and signal changes suggesting infarction in the thalamus and basal ganglia bilaterally. The straight sinus and internal cerebral vein (ICV) were dense on CT. On angiography, the vein of Galen (VG) and straight sinus were not seen. Following clinical recovery, CT and MRI became normal, and angiography showed recanalization of the VG and ICV. The relationship between cerebellar infarction and DCVT, and signal changes on CT and MRI are discussed. (orig.). With 4 figs., 1 tab

    Thrombosis of venous sinuses associated with thyrotoxicosis is rare, and isolated transverse and sigmoid sinus thrombosis is rarer and reported only once previously. We present a case of Graves disease, who suffered unilateral sigmoid and transverse sinus thrombosis with intracranial hemorrhage. A 42-year-old female, a diagnosed case of Graves disease, presented to us with headache, drowsiness, and hemiparesis. Computed Tomography revealed a large right temporo-parieto-occipital venous infarct. The patient needed surgical intervention in the form of decompressive craniotomy following which she improved, and on follow-up is having no deficits. Thrombophilia profile showed a low Protein S and Anti thrombin III (AT III) levels. Deranged thrombophilia profile in combination with the hypercoagulable state in thyrotoxicosis, most likely precipitated the thrombotic event. Timely surgical intervention can be offered in selective cases with a good clinical outcome.

    Full Text Available The dural sinus thrombosis is an uncommon complication of a commonly done procedure of central venous catheterisation. We present a case of massive hemorrhagic venous infarct with gross cerebral edema due to dural sinus thrombosis along with right internal jugular vein thrombus. A 21-year-old male patient presented to the emergency department with fever and swelling of the right neck four days following discharge after his prior hospitalization two weeks ago for acute renal failure due to severe gastroenteritis, when he underwent hemodialysis through right internal jugular access. On presentation, he was conscious, with swelling on right side of the neck, which was diagnosed as right internal jugular vein occlusion. However, he rapidly dete-riorated and developed signs of raised intracranial pressure despite being on treatment with heparin. He was diagnosed as having massive hemorrhagic cerebral venous infarct with gross cerebral edema complicated with shift of the ventricles to the left due to dural sinus thrombosis. Despite emergency decompressive craniotomy, he succumbed in the next two days due to coning. Asymptomatic catheter-related thrombosis is frequent in the intensive care units, but major complications like retrograde extension into dural sinus causing thrombosis is rare. A high index of suspicion is required to diagnose this major catastrophe for an early and meaningful intervention.

    Distant cutaneous metastases from cervical malignancies are uncommon, with scalp metastases being exceptional events. We present the case of a 53-year-old postmenopausal lady with adenocarcinoma of the uterine cervix that metastasized to the scalp with superior sagittal sinus thrombosis 8 months after diagnosis. In contrast to the seven prior cases of scalp metastases of cervical squamous cell carcinoma reported in published reports, ours is the first documentation of such an occurrence in cervical adenocarcinoma. Superior sagittal sinus thrombosis has not been reported with this tumour in the past.

    A 20-year-old female, university student presented with severe, throbbing, unilateral headache, nausea and vomiting that started 2 days ago. The pain was aggravated with physical activity and she had photophobia. She had been taking contraceptive pills due to polycystic ovary for 3 months. Cranial computed tomography was uninformative and she was considered to have the first attack of migraine. She did not benefit from triptan treatment and as the duration of pain exceeded 72 h further imaging was done. Cranial MRI and MR venography revealed a central filling defect and lack of flow in the left sigmoid sinus caused by venous sinus thrombosis. In search for precipitating factors besides the use of contraceptive pills, plasma protein C activity was found to be depressed (42%, normal 70-140%), homocystein was minimally elevated (12.7 μmol/L, normal 0-12 μmol/L) and anti-cardiolipin IgM antibody was close to the upper limit.

    Full Text Available Background: Cerebral venous sinus thrombosis (CVST is a rare form of stroke seen in young and middle aged group, especially in women due to thrombus of dural venous sinuses and can cause acute neurological deterioration with increased morbidity and mortality if not diagnosed in early stage. Neurological deficit occurs due to focal or diffuse cerebral edema and venous non-hemorrhagic or hemorrhagic infarct. Aim and Objectives: To assess/evaluate the role of Magnetic Resonance Imaging (MRI and Magnetic Resonance Venography (MRV as an imaging modality for early diagnosis of CVST and to study patterns of venous thrombosis, in detecting changes in brain parenchyma and residual effects of CVST using MRI. Materials and Methods: Retrospective descriptive analysis of 40 patients of CVST diagnosed on MRI brain and MRV was done. Results: 29/40 (72.5% were males and 11/40 (27.5% were females. Most of the patients were in the age group of 21-40 years (23/40-57.5%. Most of the patients 16/40 (40% presented within 7 days. No definite cause of CVST was found in 24 (60% patients in spite of detailed history. In 36/40 (90% of cases major sinuses were involved, deep venous system were involved in 7/40 (17.5% cases, superficial cortical vein was involved in 1/40 (2.5% cases. Analysis of stage of thrombus (acute, subacute, chronic was done based on its appearance on T1 and T2WI. 31/40 (77.5% patients showed complete absence of flow on MRV, while 9/40 (22.5% cases showed partial flow on MR venogram. Brain parenchyma was normal in 20/40 (50% patients while 6/40 (15% cases had non-hemorrhagic infarct and 14/40 (35% patients presented with hemorrhagic infarct. Conclusion: Our study concluded that MRI brain with MRV is sensitive in diagnosing both direct signs (evidence of thrombus inside the affected veins and indirect signs (parenchymal changes of CVST and their follow up.

    A 46 year old patient presented with visual loss in the left eye during the previous months. Ophthalmoscopic examination and magnetic resonance angiography found the presence of papilledema due to thrombosis in superior sagittal sinus. The examination findings revealed a mantle cell lymphoma. Cerebral venous thrombosis is an unusual cause of papilledema. This type of thrombosis may be secondary to hyper-viscosity within a context of a paraneoplastic syndrome. Copyright © 2015 Sociedad Española de Oftalmología. Published by Elsevier España, S.L.U.

    Full Text Available Abstract Background Cerebral venous sinus thrombosis is an infrequent disease with a variety of causes. Pregnancy, puerperium, contraceptive pills and intracranial infections are the most common causes. The patient may present with headache, focal neurological deficits and seizures. The clinical outcome is highly variable and treatment with heparin is advised. Case presentation The patient is a 22 year old male who presented with headache, repeated vomiting and papilledema. He was a bodybuilder doing exercise since 5 years ago, who had used nandrolone decaonoate 25 milligrams intramuscularly during the previous 5 months. Brain MRI and MRV showed superior sagital and transverse sinus thrombosis and extensive investigations did not reveal any known cause. Conclusions We suggested that androgen was the predisposing factor in our patient. Androgens may increase coagulation factors or platelet activity and cause arterial or venous thrombosis. As athletes may hide using androgens it should be considered as a predisposing factor for thrombotic events in such patients.

    Full Text Available Thrombosis of the cerebral veins and sinuses is an infrequent cerebrovascular disorder. Because the highly variable symptoms, recent neuroimaging plays a key role in the diagnosis. Abducens nerve palsy as a focal neurological deficit is a rare clinical manifestation in these patients. We present two cases with sudden onset of diplopia and headache. Case 1: A 3-year old girl with B cell lymphoblastic leukemia developed bilateral abducens deficit and bilateral optic disc edema after treatment including L-asparaginase. Thrombosis of the right jugular vein, sagittal and right sigmoid sinuses was visualized on magnetic resonance imaging (MRI and magnetic resonance venography (MRV. Symptoms gradually resolved after treatment with enoxiparine and MRV demonstrated recanalization.Case 2: A 75-year old female with medical history of arterial hypertension presented with headache and sudden left abduction deficit. Computerized tomography (CT scan was normal. MRI and MRV revealed aging brain and disruption of venous flow at the left internal jugular vein, suspecting thrombosis. Extracranial colour duplex sonography and CT angiography proved haemodinamic equivalent of left internal jugular vein thrombosis due to sclerotic pathology of aortic arch.Our first case illustrates the role of improved neuroimaging techniques as the best method for diagnosis of cerebral veins and sinuses thrombosis, presenting with abducens nerve palsy. With second case the potential neuroimaging pitfalls concerning the accurate diagnosis of these cerebrovascular disorders with neuro-ophthalmologic manifestation are discussed.

    Full Text Available Objective To investigate the clinical and imaging manifestations of cerebral venous sinus thrombosis (CVST, and the clinical effect of combined treatment of anticoagulation and endovascular thrombolysis. Methods and Results The clinical manifestations of 22 CVST patients were highly variable. Headache (90.91%, 20/22 was the most frequent symptom, and conscious disturbance, seizure and focal neurological deficits were commonly present. Plasma D-dimer level was elevated in 12 patients (54.55%. Lumbar puncture was performed in 14 patients, in whom intracranial hypertension was present in 9 patients (9/14 with no characteristic changes in routine and biochemical examination of cerebrospinal fluid (CSF. Brain CT/MRI and CTV/MRV showed direct signs of CVST in all 22 patients, involving superior sagittal sinus, transverse sinus, sigmoid sinus, straight sinus and cortex veins, parenchymal lesions (infarction, hemorrhage and white matter abnormalities in 13 patients (59.09%, subarachnoid hemorrhage (SAH in 2 patients (9.10% and subdural hematoma in one patient (4.55%. The involved cerebral sinuses revealed by DSA were superior sagittal sinus in 13 patients (59.09% , transverse sinus in 17 patients (77.27%, sigmoid sinus in 14 patients (63.64%, inferior sagittal sinus in 2 patients (9.10%, straight sinus in 4 patients (18.18%, vein of Galen in one patient (4.55% and jugular vein in one patient (4.55%. Two thrombosed sinuses were found in 9 patients (40.91% and 3 or more thrombosed sinuses in 8 patients (36.36% . As no clinical improvements and progressive exacerbation were observed several days after heparin sodium intravenous drip or lower molecular weight heparin (LMWH hypodermic injection with oral warfarin anticoagulant therapy, urokinase thrombolysis in venous sinus or artery was applied in 21 patients (95.45%. After (25.70 ± 12.18 d treatment with anticoagulation, the modified Rankin Scale (mRS score of 13 patients (59.09% reached 0-1, 4 patients

    Posterior fossa dural venous sinus thrombus is a well-described complication of head trauma, especially when fracture crosses the dural sinus grooves or in association with epidural hemorrhage. We have found that post-traumatic posterior fossa epidural hematoma compressing a dural venous sinus can mimic dural venous thrombus. To discuss the CT and MRI findings of posterior fossa epidural hemorrhages simulating sinus thrombosis, to make radiologists aware of this important imaging pitfall. We describe radiologic findings in four children in whom a posterior fossa epidural hemorrhage mimicked dural venous sinus thrombus. Routine CT head and CT venography were obtained on Toshiba volume and helical CT scanners. MRI and MR venography were performed on a Philips scanner. In all cases there was medial displacement and compression of the posterior fossa dural venous sinuses without intraluminal thrombosis. The epidural hemorrhage was seen tracking along sinus grooves in the occipital bone, peeling the dura containing the sinuses from the calvarium and compressing the sinus, simulating thrombosis on axial CT views. Both venous sinus thrombosis and posterior fossa epidural hemorrhages in children are well-described complications of head trauma. Posterior fossa epidural hemorrhage can mimic a sinus thrombus by compressing and displacing the sinuses. It is important to recognize this pitfall because treatment of a suspected thrombus with anticoagulation can worsen epidural hemorrhage. (orig.)

    Full Text Available A 36-year-old, healthy man was admitted to the emergency department with a traumatic brain injury with an injury severity score of 25 points. The head computed tomography revealed a subarachnoidal, epidural hemorrhage as well as a fracture of the occipital calotte. Intracranial pressure (ICP management was installed according to the LUND concept. In the following scan an angiography revealed a thrombosis of the sinus sigmoideus and transversus. Located next to the fractured skull, the thrombosis was highly likely traumatic, caused by the head trauma. As there was only a little congestion of the blood flow, no lysis or thrombectomy was performed. To lower ICP, a craniectomy was performed. After seven days, mechanical ventilation was terminated. Four days later the patient was already stable enough to be discharged from the surgical itensive care unit.

    Factor VII (FVII) deficiency is one of the rare inherited bleeding disorders. Thrombosis has been occasionally described in inherited FVII deficiency. Here, we report a young female with undiagnosed FVII deficiency who presented with cerebral venous sinus thrombosis (CVST). Oral contraceptive pill was found to be prothrombotic risk factor. The CVSToccurred in spite of the congenital FVII deficiency indicating that no definitive antithrombotic protection is assured by this defect. Low molecular weight heparin and anti-Xa assay were found to be safe choice of anticoagulation and monitoring, respectively, in this patient.

    Full Text Available Preeclampsia is a leading cause of maternal mortality and morbidity worldwide. The neurological complications of preeclampsia and eclampsia are responsible for a major proportion of the morbidity and mortality for women and their infants alike. Hormonal changes during pregnancy and the puerperium carry an increased risk of venous thromboembolism including cerebral venous sinus thrombosis (CVST. Factor 5 leiden (FVL is a procoagulant mutation associated primarily with venous thrombosis and pregnancy complications. We report a patient with FVL mutation who presented with CVST at 24th week of pregnancy and was diagnosed as HELLP syndrome at 34th week of pregnancy.

    2012-01-01

    Full Text Available Fetal dural sinus thrombosis is a rare finding. Most cases have been terminated without long-term follow-ups. Recently some reports have indicated the potentially favorable evolution of fetal dural sinus thrombosis. Most of the fetuses showing symptoms have been delivered with normal neurologic outcome. We report a case of fetal dural sinus thrombosis. Serial ultrasound and magnetic resonance images (MRI showed the shrinkage of the thrombosis which indicated good prognosis. No physical or neurological abnormality was observed at 8-months follow-up. Conservative treatment is appropriate to prenatally diagnosed dural sinus thrombosis with favorable prognostic factors. Serial MRI or ultrasound should be taken every 1-2 months to monitor the thrombosis development and fetal well-beings.

    Full Text Available BACKGROUND CVT is a rare type of cerebrovascular disease that can occur at any age. The widespread use of neuroimaging now allows for early diagnosis and has completely modified our knowledge on this disorder. CVT is more common than previously thought and it is recognised as a disorder with a wide spectrum of clinical presentations. AIMS & OBJECTIVE  To establish the clinical spectrum of the disease.  To determine the relationship between clinical findings, lab investigations and magnetic resonance imaging with venogram findings in CVT. MATERIALS AND METHODS The purpose of the study was explained to the patients and an informed written consent was obtained. Patients presenting with signs and symptoms suggestive of cerebral venous sinus thrombosis were evaluated. The diagnosis of cerebral sinus venous thrombosis is to be confirmed by MRI combined with MR venogram. The patients were analysed for clinical presentations, signs and symptoms, imaging findings, location and extent of the thrombus, and parenchymal lesions and based on the data to establish the correlation between clinical and MRI/MRV findings. Unpaired ‘t’ test and Chi square test were used to analyse the significance. RESULTS 47% of the cases had a sub-acute onset while 40% had acute onset of symptoms. Headache is the most common presentation followed by seizures and focal neurological deficits and 21% of the cases presented with altered sensorium. Superficial sinuses were involved in 79% of cases. Most common site is superior sagittal sinus and superficial cortical veins. Deep sinus was involved in 21% of cases. 62% of patients had a haemorrhagic infarct or an associated finding. 13.2% succumbed to the illness. MRI/MRV proved to be better investigation to confirm the diagnosis than CT brain. DISCUSSION AND CONCLUSION The spectrum of the disease includes headache, seizures, focal neurological deficits, altered sensorium and other neurological signs. Most commonly superficial

    Primary varicella zoster virus (VZV) infection, predominantly in the pediatric population, presents with pyrexia and a classic pruritic vesicular rash. In adults, although less common, it is more severe and linked to more complications. Neurological complications, which account for less than 1% of all VZV complications, include meningitis, encephalitis, arterial vasculopathy, and venous thrombosis. We present a case of a 39-year-old male who developed extensive cerebral venous sinus thrombosis following primary VZV infection. Venous thrombosis in VZV has been suggested to be caused by autoantibodies against protein S, pre-existing hypercoagulability, or endothelial damage. The patient was acutely managed using intravenous acyclovir and heparin. Long-term anticoagulation therapy with warfarin was continued after discharge. We concluded that clinicians should be aware of the rare complications of this common pathology so that a timely diagnosis can be made, followed by prompt management. Further studies need to be done to better understand acute cerebral venous sinus thrombosis secondary to VZV.

Conventional magnetic imaging (MRI) and magnetic resonance venography (MRV) are often used to detect venous sinus thrombosis, but these techniques are prone to technical problems. Catheter angiography is sometimes required as the final arbiter in the evaluation of the dural venous sinuses. Recent technical developments in MR scanning have allowed the development of dynamic subtraction MRA. This technique is beginning to be applied to the assessment of intracranial vascular malformations. We have recently applied the technique to the imaging of the dural venous sinuses, and describe our early experience with the technique. Imaging was performed on a Philips Intera 1.5T scanner with gradient strength 33 mT and slew rate 130 T/m/sec. T1-weighed fast field echo imaging was performed (flip angle 400, TR 1.5 msec) during bolus injection of gadolinium (5ml gadolinium followed by a 10 ml saline chaser) at 5-6 ml/sec using a MRI-compatible pump injector. Slice thickness depended on the plane of acquisition, but was between 100- 150 mm. Images were acquired in three orthogonal projections in each case, using 3 separate contrast injections. Mask images were obtained before the arrival of contrast, and subtracted reconstructed images were obtained in real time, providing a dynamic display of the intracranial circulation including the dural venous sinuses. Frame rate was 1 frame per 0.8 seconds. We will present dynamic MR angiographic images in a number of patients. Normal appearances and those seen in venous sinus thrombosis will be presented in the video display. Dynamic MR venography is a new technique for the imaging of dural venous sinuses. In our practice, it has proved a valuable adjunct for the imaging of patients with dural venous sinus thrombosis. Copyright (2002) Blackwell Science Pty Ltd

    Full Text Available Cerebral venous sinus thrombosis (CVST is a relatively rare cerebrovascular disease, of which the risk has been documented in patients with numerous conditions. However, CVST has never been previously described in association with the use of a diagnostic curettage in patient with uterine fibroid. Herein, we described a 43-year-old woman who presented with recurrent convulsive seizures and severe and progressive headache 1 day after a diagnostic curettage of the uterus, which was confirmed to be uterine fibroid pathologically later, and her condition subsequently progressed to confusion. Brain magnetic resonance imaging (MRI revealed an acute extensive thrombosis of the left transverse and sigmoid sinus and the ipsilateral cerebellum infarction. Evaluation for primary thrombophilia revealed that an iron deficiency anemia (IDA due to the fibroid bleeding induced menorrhagia together with a diagnostic curettage might be the sole hypercoagulable risk factor identified. Treatment with anticoagulation led to full recovery of her symptoms and recanalization of the thrombosis was proven on magnetic resonance venography (MRV 2 months later. We suggest that CVST should be recognized as a potential complication related to this diagnostic technique, especially in patient with IDA. The early diagnosis and timely treatment would be of significance in improving the prognosis of this potentially lethal condition.

    Controversy exists as to whether sinus thrombosis is the cause or the result of dural arteriovenous fistula (DAVF) and to whether DAVF are congenital or acquired lesions, especially in children. An infant presented with rupture of an anterior communicating artery aneurysm diagnosed with computed tomography angiography and catheter angiography. Pretreatment hospital course was complicated by extensive dural sinus thrombosis. Subsequent arteriography showed a new adult-type dural arteriovenous fistula to the previously thrombosed right sigmoid sinus. This is the first report of definitive angiographic documentation of the development of an adult-type DAVF after recanalization of a thrombosed dural sinus in a child. This case confirms the acquired etiology of at least one type of DAVF in children, even at this young age. We review the previously documented cases of formation of DAVF subsequent to sinus thrombosis with serial angiography in adults. (orig.)

    Full Text Available Background Cerebral venous sinus thrombosis (CVST is a special type of cerebrovascular disease with high morbidity and mortality which often has an unpredictable outcome. It is usually misdiagnosed because of different causes and variable clinical manifestations. How to improve the diagnosis and therapy of CVST is always the hotspot in clinic. This article aims to investigate the effective and safe strategies in the treatment for CVST. Methods Clinical data of 52 patients diagnosed with CVST were retrospectively analyzed. These patients were subdivided into mild type and severe type according to the features of symptoms, signs, lumbar puncture pressure and imaging. The patients with mild type were treated with systemic anticoagulant therapy combined with intravenous thrombolysis [continuous intravenous infusion of heparin (12.50-25 × 103 U/d for 7-10 d followed by a continuous infusion of urokinase (0.50-0.75 ×106 U/d for 5-7d]. The patients with severe type were treated with endovascular thrombolysis [injection of urokinase (0.50-1 × 106 U, 0.10 × 106 U/min via carotid or vertebral artery; or intravenous infusion of urokinase 1 ×106 U/d and heparin 25 ×103 U/d for 5-7 d], and superior sagittal sinus cut-open/ intrasinus thrombolysis separately. All the patients took oral warfarin for 6-12 months, and follow-up was performed after operation by the method of magnetic resonance venography (MRV. Results Among the 27 cases of mild type receiving systemic anticoagulant agents and intravenous thrombolysis, 14 were cured; 9 were improved; 4 were ineffective. Among the 22 cases of severe type receiving systemic anticoagulant drugs and endovascular thrombolysis, 18 were cured; 3 were improved; 1 was dead. The left 3 cases with gravis type received superior sagittal sinus cut-open/intrasinus thrombolysis and were cured. The period of follow-up was between 6 months and 60 months (the median time was 36 months, and no recurrence happened. Conclusion

    The main objectives of the present study are to assess the incidence of cerebral venous thrombosis (CVT) presenting as isolated subarachnoid hemorrhage (SAH) and to determine the occurrence of cortical venous thrombosis (CoVT). Among 332 patients with CVT, investigated with the same CT and MR standardized protocol, 33 (10 %) presented with SAH, associated in 11 cases with hemorrhagic infarct or intracerebral hemorrhage. This study is based on 22 cases of CVT presenting as SAH in the absence of hemorrhagic brain lesion. Diagnosis of sinus thrombosis was established on T2* and magnetic resonance venography and that of CoVT on T2* sequence. Diagnostic of SAH was based on fluid-attenuated inversion recovery (FLAIR) sequence. CVT involved lateral sinus in 18 patients, superior sagittal sinus in 16, and straight sinus in 1. Cortical veins were involved in all patients, in continuity with dural sinus thrombosis when present. SAH was circumscribed to few sulci in all cases and mainly localized at the convexity (21 cases). CoVT implied different areas on the same side in four patients and was bilateral in seven. There was no perimesencephalic or basal cisterns hemorrhage. Cortical swelling was present in 12 cases, associated with localized edema. All patients except one had a favorable outcome. This report shows that the incidence of CVT presenting as isolated SAH is evaluated to 6.4 % and that SAH is, in all cases, in the vicinity of CoVT and when dural thrombosis is present in continuity with it.

    The superior sagittal sinus (SSS) and transverse sinus are the major dural sinuses that receive a considerable amount of venous drainage. The occlusion of them has been suggested to cause intracranial hypertension, hemorrhage, and lead to potentially fatal consequences. We reported a 35-year-old woman with headache presented to our emergency department with a decreased level of consciousness and epileptic seizures. The examination of speech, higher mental function, and cranial nerve were normal. Computed tomography (CT) demonstrated both subarachnoid and intraparenchymal hemorrhage and brain edema at the right temporal lobe accompanied by high density shadow in the right transverse sinus. Digital subtraction angiography (DSA) revealed extensive thrombosis of the SSS and bilateral transverse sinus. The SSS and transverse sinus thrombosis, accompanied by right temporal lobe hemorrhage, subarachnoid hemorrhage (SAH). An emergent mechanical thrombectomy by placed Solitair AB stent in the SSS, respectively, passed left and right sigmoid sinus-transverse sinus route. We removed the most clots, DSA revealed recanalization of the SSS and left transverse sinus was seen with normalization of the venous outflow, the occlusion of right transverse sinus was still present. There were 4 hours after patient back to neurosurgical intensive care unit (NICU), patient appeared anisocoria (R/L:4.0/2.5 mm), bilateral light reflexes disappeared, then we took a CT reexamination revealed intraparenchymal hemorrhage increased, brain edema was aggravated at the left temporal lobe, and mild midline shift. Subsequently, we performed decompressive hemicraniectomy and puncture the hematoma supplemented by B ultrasonic. Anticoagulation treatment was initiated 24 hours after surgery, and follow-up DSA showed gradually improved patency in the SSS and bilateral transverse sinus. Despite occlusion of the SSS and bilateral transverse sinus, patient's symptoms resolved after the operations and he

    Background: Cerebral venous sinus thrombosis is a common but highly under-recognised condition, which is missed not only by general practitioners but also by neurologists. Computerised tomography (CT) or magnetic resonance imaging (MRI) of brain alone is not sufficient to diagnose this condition. Objective of this study was to explore the pattern of magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) changes in cerebral venous sinus thrombosis (CVST). Methods: This was a descriptive study in which 52 cases of cerebral venous sinus thrombosis with special emphasis on their MRI and MRV findings were included. The study was conducted in Neurology Unit, Lady Reading Hospital, Peshawar, Pakistan, from January 2010 to July 2011. All patients suffering from cerebral venous sinus thrombosis were included in the study. Multi-planar/multi-sequential, Tesla 1.5 MRI/MRV time of flight images were done in all cases where there was suspicion of cerebral venous sinus thrombosis. Results: Out of 52 patients with cerebral venous sinus thrombosis 41 (78.84%) were female and 11 (21.15%) were male. Mean age was 37+-5 years. Definite risk factors were found in 38 (73.076%) patients with pregnancy, use of oral contraceptives or puerperium being the most frequently found risk factor in 20 (73.076%) patients. Most common complaint was headache found in 41 (78.84%) patients, followed by focal neurological deficits, and altered mental status and seizures. Papilloedema was seen in 20 (38.46%) patients. The cerebral venous sinuses most frequently involved were transverse and sigmoid sinuses in 17 patients (32.69%) while superior sagittal sinus alone in 10 (19.23%) patients. Overall CT brain was normal in 30% and MRI brain in 23.07% patients; however, MRV of these patients revealed CVST. Conclusion: Imaging plays a primary role in the diagnosis of cerebral venous sinus thrombosis because the clinical picture of CVST is non-specific and highly variable. Thrombosis of

    Objective: To discuss the curative effect of unremitting pump infusion of microdose urokinase (100000 u / 24 h) into the cerebral venous sinus in treating thrombosis in cerebral venous sinus which had anatomical variation. Methods: Mechanical disruption of the thrombus and unremitting pump infusion of microdose urokinase (100000 u / 24 h) into the cerebral venous sinus for 48-96 hours were employed in 9 patients with thrombosis in anatomically varied cerebral venous sinus. After the procedure the original disorder was actively treated and the anticoagulant therapy was continued for 6 months. A follow-up of 6-12 months (mean 10 months) was conducted. Results: Recanalization of the previously occluded cerebral venous sinus was obtained in all 9 patients. The dose of urokinase was 100 000 u / 24 h in 8 patients. For the remaining one patient the dose of urokinase was 100000 u / 24 h in the first 48 hours, then the dose was increased to 250000 u / 24 h. Excellent result was obtained in all patients. Conclusion: Unremitting pump infusion of microdose urokinase into the cerebral venous sinus can effectively treat the thrombosis in anatomically varied cerebral venous sinus. (authors)

    Full Text Available We report the case of a 4-year-old boy with acute lymphoblastic leukemia in high-risk group who suffered from generalized tonic-colonic seizure evolving into status epilepticus, and subsequent left hemiparesis during his first reinduction chemotherapy, consisting of dexamethasone, vincristine, l-asparaginase, and epirubicin. Superior sagittal sinus and cerebral venous thrombosis, predominantly in right side, were proved by brain magnetic resonance imaging. After aggressive treatment with low-molecular weight heparin (LMWH, left hemiparesis improved in 1 week. And he was fully ambulatory 3 weeks later. The second cycle of reinduction chemotherapy was conducted smoothly with the concomitant use of LMWH. This case illustrates the strong correlation of the rare thrombotic complication, superior sagittal sinus thrombosis, and hypercoagulable status secondary to combination use of l-asparaginase and corticosteroid. Early and vigilant recognition of superior sagittal sinus thrombosis and prompt anticoagulation with LMWH may prevent further neurological damage.

    Superior sagittal sinus thrombosis (SSST) is an uncommon cause of stroke, whose symptoms and clinical course are highly variable. It is frequently associated with a variety of hypercoagulable states. Coagulation abnormalities are commonly seen in patients with hyperthyroidism. To the best of our knowledge, there are few reports on the association between hyperthyroidism and cerebral venous thrombosis. We report on a 31-year-old male patient with a six-year history of hyperthyroidism who devel...

    Full Text Available Cerebral venous sinus thrombosis (CVT is a rare cerebrovascular disease with variable presentation. CVT rarely causes hydrocephalus. Communicating hydrocephalus due to CVT is extremely rare. We describe a patient of CVT presenting with chronic headache and communicating hydrocephalus. The patient was successfully treated with ventriculoperitoneal (VP shunt. A 40 year old man presented with moderate to severe headache since six months and progressive visual loss since two months. Head Computed tomogram showed mild hydrocephalus without obstruction. Lumbar puncture (LP demonstrated elevated pressure but was otherwise normal. Magnetic resonance venogram showed extensive CVT. Repeated CSF drainage and thecoperitoneal shunt did not relieve the severe headache hence a VP shunt was placed. Post shunt headache subsided with resolution of hydrocephalus. CVT can present as communicating hydrocephalus. Gradual reduction of intra-ventricular pressure by repeated LPs followed by VP shunt can safely treat hydrocephalus due to CVT.

    Prior to the advent of efficacious antimicrobial agents, the mortality rate from cavernous sinus thrombosis (CST) was effectively 100%. There have been very few reports of CST associated with tooth extraction. A 40-year-old female presented to the emergency room with swelling over the right side of the face and history of extraction in the upper right region by an unregistered dental practitioner. The patient presented with diplopia, periorbital ecchymosis, and chemosis of the right eye. A computed tomography scan revealed venous dilatation of the right superior ophthalmic vein. The patient was immediately treated with incision and drainage, intravenous antibiotics, and heparin (low molecular weight). Unfortunately, the patient died two days after surgery due to complications from the disease. CST is a rare disease with a high mortality rate. Therefore, dental health education in rural areas, legal action against unregistered dental practitioners, early diagnosis, and aggressive antibiotic treatment can prevent future mortality resulting from CST.

    2007-01-01

    To assess the presentation of allergic fungal sinusitis and describe the line of management in our setup. Culture and sensitivity / fungal stain proven 20 cases of allergic fungal sinusitis were selected for the study, irrespective of age and gender. Data including age, gender, socioeconomic status, signs, symptoms, laboratory findings (especially Immunoglobulin E and eosinophil count) and imaging studies (Computed Tomography and /or Magnetic Resonance Imaging) were noted for the study. Pre and postoperative medical treatment, surgery performed, follow-up; residual/recurrence disease and revised surgery performed were also recorded. In this series, allergic fungal sinusitis was a disease of younger age group with an average age of 20.75 years with male dominance (70%). Poor socioeconomic status (80%), allergic rhinitis (100%) and nasal polyposis (100%) were important associated factors. Nasal obstruction (100%), nasal discharge (90%), postnasal drip (90%) and unilateral nasal and paranasal sinuses involvement (60%) were the commonest presenting features. Aspergillus (60%) was the most common etiological agent. In all cases (100%), increased eosinophil count and IgE levels were present. Orbital (20%) and intracranial (10%) involvement were also seen. Surgical management was preferred in all cases. Functional endoscopic sinus surgery in 90% cases and lateral rhinotomy in 10% cases were performed. Recurrence / residual disease was seen in 20% cases. In this series, allergic fungal sinusitis was seen in immunocompetent, young males, belonging to poor socioeconomic status, suffering from allergic rhinitis and nasal polyposis, presenting with nasal obstruction, nasal discharge and postnasal drip. Functional endoscopic sinus surgery was the most important problem solving procedure while lateral rhinotomy was reserved for extensive disease. (author)

    Directory of Open Access Journals (Sweden)

    Shahriyar Alian

    2014-01-01

    Full Text Available Leptospirosis is a bacterial disease that is caused by pathogenic spirochetes of the genus Leptospira. It can affect humans and animals. In humans, it can lead to a wide spectrum of symptoms. It is known as the most common zoonosis in the world. The typical presentation of the disease is an acute biphasic febrile illness with or without jaundice. Less common clinical manifestations may result from involvement of different human body systems. In many places, this disease may be under-diagnosed, especially when associated with neurological complications. Moreover, without treatment, leptospirosis can lead to organ damages, and even death. Neurological complications are uncommon and are reported in a few cases. Cavernous sinus thrombosis syndrome and brainstem involvement are rare complications of leptospirosis and are associated with a high mortality risk. To our knowledge, no such cases have been reported in the literature.

    Objective: To discuss the curative effect and safety of a modified thrombolytic scheme in the treatment of cerebral sinus thrombosis. The new scheme adopts unremitting pump infusion of microdose urokinase (100,000 IU/24 h) into the cerebral venous sinus. Methods: The new therapeutic scheme was conducted in 21 patients with cerebral sinus thrombosis. Mechanical disruption of the thrombus was applied by moving the micro guidewire back and forth in the thrombus site, and unremitting pump infusion of urokanase for 48-96 hours with the lowest dose of 100,000 u/24 h was used. A follow-up of 6-12 months was made. Results: Recanalization of the occluded cerebral venous sinus was obtained in all 21 patients. The total urokinase dose of 100,000 u/24 h was used in 12 patients. For the other 9 patients the urokinase dose was 100,000 u/24 h in the first 48 hours, then the dose was increased to 250,000 u/24 h. No serious complications occurred. All patients showed a good prognosis. Conclusion: For the treatment of cerebral sinus thrombosis, this modified thrombolytic scheme is more safe and effective with less hemorrhage as compared to the classical one, since it may avoid certain complications caused by the use of large dose of thrombolytic drug .

    Haber, Daniel Martiniano

    2008-12-01

    Full Text Available Introduction: Mucormycosis is a rare opportunistic infection caused by Mucorales fungi, and the Rhizopus is the most common one (70% of the cases. It is an acute invasive fungal disease whose form is disseminated, cutaneous, pulmonary, gastrointestinal and rhino-orbitocerebral. The latter is the most common form and its symptoms comprise of unilateral sinusitis, fever and headache. Once established in the orbit the symptoms can be chemosis, diplopia and reduced vision. The infection can spread to the brain via the orbital apex, orbital arteries or via the cribriform plate. Mucormycosis is a medical emergency and the treatment consists of a surgery to an aggressive debridement and in the use of antifungal therapy. Despite the appropriate management, the mortality rate can reach 40% of the cases. One possible intracranial complication of Mucormycosis is the Cavernous Sinus Thrombosis which is a rare and fatal infective disease. The initial symptoms of Cavernous Sinus Thrombosis are headache, retro-orbital pain, periorbital edema, proptosis, diplopia and reduced vision. Case Report: We describe the case of 43-year-old woman with medical history of diabetes mellitus and use of immunosuppressant drugs after kidney transplantation. The patient developed Acute Bacterial Sinusitis and Rhino-orbitocerebral Mucormycosis associated with Cavernous Sinus Thrombosis.

    Four adult patients were diagnosed as having dural sinus thrombosis (DST) by means of magnetic resonance (MR). In the three cases of acute thrombosis, MR disclosed diffuse or segmental hyperintensity in the sinuses involved, which persisted regardless of the sequence and orientation of the plane selected. MR angiography (MRA) provided diagnostic information that proved useful in the chronic case, as well as in the two cases in which follow-up was carried out to determine the degree to which permeability was restored to the sinuses involved. MR diagnosis of DST can produce false positives and negatives, the causes of which should be known, as well as the ways to avoid them, in order to prevent diagnostic errors. MR, when applied and interpreted correctly, can be considered the first, and in many cases the only, choice as a diagnostic method in DST. (Author)

    2017-01-01

    Full Text Available Background: In dural venous sinus thrombosis (DVST, the mortality ranges 5–30%. Deep venous system involvement and septic dural sinus thrombosis have a higher mortality rate. In acute occlusion, collateral flow may not be established, which may result in significant edema and mass effect. Endovascular interventions may be considered as a treatment option in appropriate high-risk patients with DVST. Materials and Methods: Eight patients with magnetic resonance imaging (MRI-confirmed dural sinus thrombosis, who did not respond to the conventional standard medical treatment, were subsequently treated with mechanical thrombectomy using the Penumbra System®. In all cases, medical treatment including anticoagulants were continued following the procedure for a minimum period of 1 year. Results: Recanalization of the dural sinus thrombosis was achieved in all 8 cases. There were no immediate or late endovascular-related complications. One death occurred due to an unrelated medical event. At 6 months, there was notable improvement in the modified Rankin Score (mRS, with 5/8 (62% patients achieving mRS of 2 or less. The follow-up ranged between 3 months and 26 months (mean: 14.5 months, and there were no new neurological events during the follow-up period. Conclusion: Cerebral venous sinus thrombosis is a rare but life-threatening condition that demands timely diagnosis and therapy. In cases of rapidly declining neurological status despite standard therapy with systemic anticoagulation and anti-edema measures, mechanical thrombectomy could be a lifesaving and effective option. In this study, good outcomes were observed in the majority of patients at long-term follow up.

    Objective Cerebral venous sinus thrombosis (CVST) is a rare cerebrovascular disease affecting young adults. The majority of the patients are female. The aim of this study is to assess the clinical associations, risk factors and outcomes of the patients with CVST. Methods The data of 75 patients with CVST admitted to our hospital between 2006 and 2016 were reviewed. Demographic and clinical features and the thrombophilic risk factors of the patients were recorded. The localizations of the thrombi were determined and modified Rankin score at the time of onset and discharge were calculated. Results The majority of our patients (78.7%) were female. Median age was 35 years (16–76). The most common symptom was headache (86.7%). In 82.6% of our patients, inherited or acquired risk factors for thrombosis were detected. Transverse sinus was the most common site of thrombosis followed by sigmoid and superior sagittal sinuses. Two thirds of the patients had involvement of multiple sinuses. The patients with the involvement of sagittal sinus had better disability at the time of admittance (p = 0.013) while the number of involved sinuses was correlated worse disability (p = 0.015). The neurologic states in the majority of the patients were improved by the end of the hospitalization period (p = 0.001). There was no significant difference in disability score at discharge between men and women (p = 0.080). No patient with CVST died in the hospitalization period. Conclusions This study is one of the largest cohort studies on CVST in our region. The results of the study disclosed that CVST had wide range of clinical manifestations and non-specific symptoms at the beginning. For that reason, in especially high risk groups for thrombosis, the diagnosis of CVST should be kept in mind. PMID:28222615

    Full Text Available La trombosis de los senos venosos durales es una rara y devastadora enfermedad. Se presenta generalmente en mujeres y ancianos, y no es frecuente en niños, aunque se reconoce ya como una causa de morbilidad y mortalidad en la población pediátrica. Se han reportado pocos casos en el mundo de neonatos afectados por esta entidad, en su mayoría fatales e insuficientemente investigados. A continuación se presenta el caso de un recién nacido con una trombosis del seno sagital que sobrevivió. Los factores predisponentes para la aparición de la enfermedad en este caso fueron la asfixia neonatal, la deshidratación severa unida al uso de una línea venosa central, y la inmovilización prolongada. Aunque la TAC contrastada no es el estudio ideal para su diagnóstico, permitió realizarlo oportunamente en este caso. El tratamiento temprano con anticoagulantes permitió una rápida recuperación y favoreció la recanalización venosa del seno involucrado. Hasta el momento no se han detectado secuelas neurológicas y el paciente tiene buen desarrollo psicomotor.Dural venous sinus thrombosis is a rare devastating disease. It is generally found in females and old people, but is infrequent in children; however, it is already recognized as a morbidity and mortality cause in the pediatric population. Few cases of newborns with this disease have been reported worldwide; most of them were poorly studied and had fatal outcomes. Here is the presentation of a newborn with sagittal sinus thrombosis, who managed to survive. The predisposing factors for the disease were neonatal asphyxia, severe dehydration together with the use of central venous line and extended immobilization. Although contrast CAT is not the ideal study, it helped to promptly arrive at the right diagnosis in this case. The early treatment based on anticoagulants allowed rapid recovery and facilitated venous retaking of the involved venous sinus. No neurological sequels have been so far

    Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSAH) is characterized by a pattern of extravasated blood restricted to the perimesencephalic cisterns, normal angiographic findings, and an excellent prognosis with an uneventful course and low risks of complication. The precise etiology of bleeding in patients with PNSAH has not yet been established. The most common hypothesis is that PNSAH is venous in origin. Intracranial venous hypertension has been considered as the pivotal factor in the pathogenesis of PNSAH. The underlying venous pathology such as straight sinus stenosis, jugular vein occlusion may contribute to PNSAH. We describe a patient in whom transverse sinus thrombosis preceded intracranial venous hypertension and PNSAH. These findings supported that the source of the subarachnoid hemorrhage is venous in origin. A 45-year-old right-handed man was admitted to the hospital with a sudden onset of severe headache associated with nausea, vomiting, and mild photophobia for 6 hours. The patient was fully conscious and totally alert. An emergency brain computed tomography (CT) revealed an acute subarachnoid hemorrhage restricted to the perimesencephalic cisterns. CT angiography revealed no evidence of an intracranial aneurysm or underlying vascular malformation. Digital subtraction angiography of arterial and capillary phases confirmed the CT angiographic findings. Assessment of the venous phase demonstrated right transverse sinus thrombosis. Magnetic resonance imaging confirmed the diagnosis of cerebral venous sinus thrombosis (CVST). Lumbar puncture revealed an opening pressure of 360 mmH2O, suggestive of intracranial venous hypertension. Grave disease was diagnosed by endocrinological investigation. Low-molecular-weight heparin, followed by oral warfarin, was initiated immediately as the treatment for cerebral venous sinus thrombosis and PNSAH. The patient discharged without any neurologic defect after 3 weeks of hospital stay. MR venography

    A girl with Down's syndrome, moyamoya disease and sagittal sinus thrombosis is described. She was diagnosed after acute neurological deterioration by MRI and angiography. Recombinant tissue plasminogen activator (r-TPA) was injected locally to recanalise the thrombus. The patient's condition significantly improved and she was discharged. After 2 years of follow-up the child remains asymptomatic. Moyamoya syndrome and cerebral venous thrombosis should not be overlooked as a cause of acute neurological deterioration in a child with Down's syndrome. MRA appears to be a safe and accurate alternative to traditional angiography for the diagnosis of moyamoya disease. Local fibrinolysis with r-TPA is the treatment of choice for cerebral venous thrombosis due to its safety and efficacy. (orig.)

    Objective: Eighty-five cases with multiple cerebral venous and venous sinuses thrombosis including the diagnosis and endovascular therapy were reported. Methods: The long T2 and short T1 signals in the related regions of multiple venous sinuses on MRI and prolonged blood circulation time of the brain with tortuous dilatation of vein in angiography were the important characteristics for the diagnosis. Of the 85 cases, the treatment procedures were consisted of injecting urokinase intermittently via common carotid artery and intra-sinus contact thrombolysis as well as warfarin intake orally. Results: Intracranial pressure of 80 cases reduced down between 230 and 300 mm H 2 O, and clinical deficits were markedly improved within 10 days. Re-angiography of 18 cases revealed recanalization partly in 5 cases and circulation time appeared near normal i 8 cases during one week after therapy. Conclusions: Combined intraarterial thrombolysis consecutively with general anticoagulation for the treatment of multiple thrombosis in cerebral venous sinuses may be one of the effective means

    We aimed to define the possible risk factors for acute and remote seizures in patients with cerebral vein and sinus thrombosis (CVST). Ninety-four patients were recruited prospectively at Al-Zahra Hospital, Isfahan, Iran, between April 2007 and April 2012. To identify seizure predictors, we compared demographic, clinical and imaging factors between patients with or without acute and remote seizures. Of the 94 patients, 32 (34%) experienced at least one seizure after CVST development. Bivariate analysis showed a significant association of remote seizure with loss of consciousness at presentation (P=0.05, OR: 5.11, 95%CI: 1.07-24.30), supratentorial lesions (P=0.02, OR: 9.04, 95%CI: 1.04-78.55), lesions in the occipital lobe (P=0.00, OR: 12.75, 95%CI: 2.28-71.16), lesions in the temporal and parietal lobes, thrombophilia (P=0.03, OR: 5.87, 95%CI: 1.21-28.39), seizure in the acute phase (P=0.00, OR: 13.14, 95%CI: 2.54-201.2) and sigmoid sinus thrombosis (P=0.00, OR: 12.5, 95%CI: 2.23-69.79). Seizures in the acute phase were also more common in patients with paresis (P=0.00, OR: 4.88, 95%CI: 1.91-12.46), hemorrhagic lesions indicated by imaging (P=0.02, OR: 2.77, 95%CI: 1.08-7.10), supratentorial lesions, lesions in the frontal (P=0.01, OR: 3.81, 95%CI: 1.28-11.31) and parietal lobes (P=0.00, OR: 5.16, 95%CI: 2-13.29), thrombophilia and history of miscarriage (P=0.03, OR: 2.91, 95%CI: 1.07-7.91). No factor predicted acute or remote seizure in a multiple logistic regression analysis. Our results demonstrate that seizure development in the acute phase is the most significant factor for development of remote seizure. Parenchymal lesions in the supratentorial area were also found to be associated with both acute and remote seizures. However, no factor was predictive of acute or remote seizures in a multivariate analysis. Copyright © 2013 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    Dural venous sinus ectasia with thrombosis (DVSET) in the fetus is a rare condition that can be diagnosed prenatally with the use of fetal MR imaging, yet with limited indication of long-term clinical significance. To describe and evaluate the diagnostic value of fetal MR imaging in the prenatal diagnosis of dural venous sinus ectasia with thrombosis and its clinical significance. We report a series of nine fetuses with dural venous sinus ectasia with thrombosis. The mothers, located in four feto-maternal centres, were referred for fetal MR imaging due to space occupying lesions identified on second-trimester antenatal ultrasound. In all but one case the dural venous sinus ectasia with thrombosis was in the vicinity of the venous confluence (VC) with various extension in the posterior dural sinuses. Antenatal follow-up imaging was performed in seven cases and showed progression in one, stable appearances in one and regression in five cases. Three pregnancies were terminated. In the remaining six cases there was no reported neurological deficit at up to 44 months of clinical follow-up. This is among the largest series of postnatal clinical follow-up in cases of prenatal diagnosis of dural venous sinus ectasia with thrombosis in the literature. Clinical follow-up suggests a good prognosis when antenatal follow-up shows partial or complete thrombus resolution. (orig.)

    Full Text Available A hamartoma is a benign, focal malformation that resembles a neoplasm in the tissue of its origin. This is not a malignant tumor, and it grows at the same rate as the surrounding tissues. We report a case of a 27-year-old male patient who presented with mild dysphagia and foreign body sensation in the throat of 1-year duration. On examination, there was a mucosal fold on the medial wall of pyriform sinus lateral to aryepiglottic fold that was acting like a sump where food particles used to get collected. Patient underwent microlaryngeal excision of the mucosal fold, and histopathological examination revealed features of hamartoma.

  6. Sinus Sigmoideus Thrombosis Secondary to Graves’ Disease:A Case Description

    2011-09-01

    Full Text Available Cerebral venous thrombosis (CVT is a distinct cerebrovascular condition that represents 0.5–1% of all strokes in the general population. Because of its procoagulant and antifibrinolytic effects [Horne et al.: J Clin Endocrinol Metab 2004;89:4469–4473], hyperthyroidism has been proposed as a predisposing factor for CVT [Saposnik et al.: Stroke 2011;42:1158–1192]. For the first time, we describe a 22-year-old right-handed woman with a sinus sigmoideus thrombosis due to Graves’ disease. Although subclinical hyperthyroidism had been detected 2 years before the onset of neurological symptoms, she did not receive any medical follow-up. Early recognition, diagnosis and treatment are of crucial importance, as Graves’ disease is a risk factor for CVT and stroke.

    Full Text Available BACKGROUND: Sinus of Valsalva aneurysm (SVA may be congenital or acquired. They could mimic ventricular tumor symptoms and cause signs and symptoms of ventricular outflow tract obstruction. They may also involve the conduction system and cause palpitations or syncopal episodes. Both transthoracic echocardiography (TTE and transesophageal echocardiography (TEE serve as quick, noninvasive methods to provide information on size and location of aneurysmal dilatation and cardiac chamber involvement. These methods can identify any associated anomalies or complications. This study presents a patient with unruptured SVA. CASE REPORT: A 46-year-old man, who had been suffering from nonspecific symptoms such as exercise intolerance and weakness for a few months, referred to our clinic in Isfahan (Iran. In TTE, a large mass was observed in the right ventricle. SVA was suspected after meticulous probing. This diagnosis was confirmed by TEE and computed tomography angiography. At open heart surgery, an SVA with a lot of clots it was removed. CONCLUSION: SVA must be kept in mind when a tumor-like mass is observed in the right ventricle. Detailed evaluation would thus be necessary to rule out SVA and to prevent wrong diagnosis and treatment that can sometimes be catastrophic. Keywords: Sinus Valsalva, Aneurysm, Cardiac Tumor.

    Otogenic lateral sinus thrombosis (LST) is a rare intracranial complication of acute otitis media (AOM), which can lead to severe neurological sequelae and death. The aim of this study was to analyze the clinical presentation, management and outcome of LST in children, investigating a possible correlation between clinical aspects, radiological findings and anatomical variations. At a tertiary Italian hospital, a retrospective review was conducted on the medical records of eight patients diagnosed with otogenic LST over a 3-year period. Four children were males and mean age was 4.7 years. All patients had a history of otitis media at diagnosis and 4/8 presented also with more than one neurological sign or symptom. Mastoiditis signs were detected in 5/8 patients. Thrombosis was diagnosed by computed tomography, enhanced magnetic resonance and magnetic resonance venography. Treatment was medical, alone or combined with surgery. Medical treatment consisted in anticoagulants eventually combined with anti-edema medication on clinical basis. Mastoidectomy and/or myringotomy±trans-tympanic drainage placement were performed in 7/8 patients. Complete vessel recanalization was obtained in 6/8 children after a median follow-up time of 4.8 months. No complications, neither clinical sequelae occurred. In our series, neurological signs and symptoms were significantly associated with the presence of hypoplasia of the contralateral venous sinus (p=0.029). LST is a severe condition occurring even in absence of otological signs, and despite adequate antibiotic therapy for AOM, which should be ruled out and promptly treated. A dominant neurological presentation is associated in our series with anatomical variations of cerebral sinus venous drainage patterns. This should be carefully evaluated and considered in diagnosis, treatment planning and prognosis. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Superior sagittal sinus thrombosis (SSST) is an uncommon cause of stroke, whose symptoms and clinical course are highly variable. It is frequently associated with a variety of hypercoagulable states. Coagulation abnormalities are commonly seen in patients with hyperthyroidism. To the best of our knowledge, there are few reports on the association between hyperthyroidism and cerebral venous thrombosis. We report on a 31-year-old male patient with a six-year history of hyperthyroidism who developed seizure and mental deterioration. Findings on brain computed tomography (CT) showed multiple hemorrhages in the subcortical area of both middle frontal gyrus and cerebral digital subtraction angiography (DSA) showed irregular intra-luminal filling defects of the superior sagittal sinus. These findings were consistent with hemorrhagic transformation of SSST. Findings on clinical laboratory tests were consistent with hyperthyroidism. In addition, our patient also showed high activity of factors IX and XI. The patient received treatment with oral anticoagulant and prophylthiouracil. His symptoms showed complete improvement. A follow-up cerebral angiography four weeks after treatment showed a recanalization of the SSS. In conclusion, findings of our case indicate that hypercoagulability may contribute to development of SSST in a patient with hyperthyroidism.

    We decided to process this theme due to its nonspecific clinical features as they often cause diagnostic problems not only to clinicians but also to diagnostic. It is important to think of this disease mainly in young women who administer hormonal contraception. Imaging methods play the crucial role in diagnostic of cerebral venous sinus thrombosis. The gold standard is a native CT of brain which shows the venous sinus thrombosis as a hyperdense lesion in the locus of the sinus (dense triangle sign), CT venography shows the sinus thrombosis as a defect in a contrast filling of the venous sinus (empty delta sign). Other investigative methods are magnetic resonance imaging or MRA. In short we also mention quite a rare but more serious thrombosis of profound cerebral veins v. cerebri magna-Galeni, vv. cerebri internae). The importance of early diagnostic and non specificity of symptoms is presented in 3 clinical cases that are the part of this work. (author)

    Cushing disease, induced by a pituitary adrenocorticotropic hormone (ACTH)-secreting adenoma, is associated with high risk of stroke. At present, transsphenoidal surgery remains the first line of therapy. Cerebral venous sinus thrombosis (CVST) is an uncommon form of stroke with variable presentations. There are no previous reports of its occurrence in patients with Cushing disease following transsphenoidal surgery. We report a patient with Cushing disease who sustained CVST several days after a second transsphenoidal surgery. With adequate care and treatment, along with timely diagnosis, the patient made a near-complete recovery with only minor sequelae. In view of the poor outcome of untreated CVST, symptoms such as severe headache, nausea and vomiting, and cerebrospinal fluid leakage after transsphenoidal surgery could be of valuable assistance in early diagnosis, allowing immediate medical intervention with consequent improved prognosis.

    Pregnancy is associated with increased risk of venous thrombotic events, including cerebral venous thrombosis. We aimed to study the complications and outcome of subsequent pregnancies in women with previous cerebral venous thrombosis. Follow-up study of women with acute cerebral venous thrombosis at childbearing age included in a previously described cohort (International Study of Cerebral Vein and Dural Sinus Thrombosis). Patients were interviewed by local neurologists to assess rate of venous thrombotic events, pregnancy outcomes, and antithrombotic prophylaxis during subsequent pregnancies. A total of 119 women were included, with a median follow-up of 14 years. Eighty-two new pregnancies occurred in 47 women. In 83% (68 of 82), some form of antithrombotic prophylaxis was given during at least 1 trimester of pregnancy or puerperium. Venous thrombotic events occurred in 3 pregnancies, including 1 recurrent cerebral venous thrombosis. Two of the 3 women were on prophylactic low-molecular-weight heparin at the time of the event. Outcomes of pregnancies were 51 full-term newborns, 9 preterm births, 2 stillbirths, and 20 abortions (14 spontaneous). In women with prior cerebral venous thrombosis, recurrent venous thrombotic events during subsequent pregnancies are infrequent. © 2017 American Heart Association, Inc.

    Combined oral contraceptives are known to confer a risk of venous thromboembolism, including cerebral venous sinus thrombosis (CVST), to otherwise healthy women. NuvaRing (Organon USA, Inc., Roseland, NJ) is a contraceptive vaginal ring that delivers 120 μg of etonogestrel and 15 μg of ethinyl estradiol per day. Its use has been associated with rare venous thromboembolic events, but few cases of CVST associated with NuvaRing have been reported. To describe a case that illustrates the increased risk of CVST associated with use of NuvaRing. We describe the case of a NuvaRing user who presented to our emergency department with a headache, who was diagnosed with CVST. Evidence suggests that NuvaRing has at least as much prothrombotic potential as combined oral contraceptives. Thus, emergency physicians should suspect serious venous thromboembolic events, including CVST, deep venous thrombosis, and pulmonary embolism, in NuvaRing users in the proper clinical setting.

  18. Cerebral Venous Thrombosis and Venous Infarction: Case Report of a Rare Initial Presentation of Smoker’s Polycythemia

    Directory of Open Access Journals (Sweden)

    Mihir Raval

    2010-11-01

    Full Text Available Introduction: Cerebral venous thrombosis is a rare initial presentation of polycythemia. If diagnosed early, treatment can reduce mortality and morbidity significantly. Often it may present with headache as the only complaint, and thus the diagnosis is likely to be missed. Case Presentation: A medically stable 31-year-old male, a chronic smoker with a ∼17 pack-year history of smoking, was admitted to the emergency room with a 2-week history of gradually worsening, severe, throbbing headache in the occipital region sensitive to light. Initial neurological examination was positive only for some involuntary motor tics of the left leg. Initial laboratory workup showed hemoglobin of 20 g/dl and hematocrit of 56.5%. The carboxyhemoglobin level was normal, but the oxygen dissociation curve was shifted to the left. Further evaluation by MRI and MRA of the brain suggested extensive and complete thrombosis of the superior sagittal sinus, right transverse sinus and right sigmoid sinus with a small venous infarct in the right parafrontal region. Given that the patient first presented with a thrombotic event, workup for primary polycythemia and hypercoagulable disorders was carried out, including JAK2 mutation evaluation, which was negative. This left us with smoking as the only risk factor and possible cause for secondary polycythemia. He improved significantly with phlebotomy and anticoagulation treatment. Conclusion: This case illustrates a rare but severe complication of secondary polycythemia stressing the importance of being aware of the risk of developing cerebral thrombosis in patients with chronic smoking exposure.

    Thrombosis of the cerebral veins and sinus are common causes of stroke. Animal models help us to understand the underlying pathophysiology of this condition. Therefore, the purpose of our study was to evaluate a well-established model for sinus sagittalis (SSS) thrombosis using micro- and nanocomputed tomography (CT) imaging. SSS thrombosis was performed in four rats. After contrast perfusion, brains were isolated and scanned using micro-CT at (8 μm) 3 voxel size to generate 3D images of the cerebral vasculature. For more detailed information on vascular perfusion territories, nano-CT imaging was performed to investigate the boundary layer of contrast-enhanced vessels and the occluded veins. The venous and arterial vascular volume fraction and gray scale measurements were obtained in the SSS thrombosis group and compared to controls. The significance of differences in vascular volume fraction and gray scale measurements was tested with analysis of variance. Results were complemented with histology. Micro-CT proved to accurately visualize and differentiate vascular occlusion territories performed in the SSS thrombosis model. Moreover, 3D micro-CT provided quantitative information on arterial and venous vascular volume fraction. Micro-CT imaging enables a total 3D visualization of complications (ventricle rupture) in the SSS thrombosis model. We established gray scale measurements by which focal cerebral ischemia could be radiographically categorized (p < 0.001). Using nano-CT, the interface of contrast-perfused and occluded veins can be visualized. Micro-CT is feasible for analysis and differentiation of perfusion territories in an animal model of focal cerebral ischemia. (orig.)

    The CT imaging and clinical presentation in 14 children with coexistent intracranial sepsis and sinusitis were reviewed. A routine CT head scan (10-mm thick semi-axial slices through the cranium done before and after intravenous contrast medium administration) was found to be an inadequate initial investigation as the intracranial collection was missed in four patients and the abnormal sinuses not shown in six. In half the children the dagnosis of sinusitis was unsuspected at the time of admission. The dominant clinical features were fever, intense headache and facial swelling in early adolescent males. In this clinical setting we recommend: (1) The routine scan is extended through the frontal and ethmoidal sinuses and photographed at a window level and width showing both bone detail and air/soft tissue interfaces; (2) direct coronal projections are performed through the anterior cranial fossa if no collection is seen on the routine study; (3) an early repeat scan within 48 h if the initial study shows no intracranial pathology but the fronto-ethomoidal sinuses are abnormal and there is a high clinical supicion of intracranial sepsis; and (4) in the presence of intracranial sepsis the vault is viewed at bone window settings to exclude cranial osteomyelitis.

    Acute mesenteric ischemia is a life-threatening vascular emergency that requires early diagnosis and intervention to adequately restore mesenteric blood flow and to prevent bowel necrosis and patient death. While, almost always superior and inferior mesenteric arteries are involved, we report a 57-year-old male with an unusual celiac artery trunk thrombosis leading to gastero-duodenal and hepato-splenic infarction, and presenting an acute liver failure.

    Portal vein thrombosis (PVT) is a serious problem with a high morbidity and mortality, often exceeding 40% of affected patients. Recently, PVT has been reported in patients after laparoscopic sleeve gastrectomy (LSG). The frequency is surprisingly high compared with other abdominal operations. We present a series of 5 patients with PVT after LSG. The treatment was not restricted simply to anticoagulation alone, but was determined by the extent of disease. A distinction is made among nonocclusive, high-grade nonocclusive, and occlusive PVT. We present evidence that systemic anticoagulation is insufficient in occlusive thrombosis and may also be insufficient in high-grade nonocclusive disease. Single private institution, United States. We present a retrospective analysis of 646 patients who underwent LSG between 2012 and 2015. In all patients, the diagnosis was established with an abdominal computed tomography (CT) scan as well as duplex ultrasound of the portal venous system. All patients received systemic anticoagulation. Depending on the extent of disease, thrombolytic therapy and portal vein thrombectomy were utilized. All patients received long-term anticoagulation. Four patients with PVT were identified. A fifth patient with PVT after LSG was referred from another center. The mean age of all patients was 49 years. One patient had a history of deep vein thrombosis (DVT). No complications were identified intraoperatively or during the hospital stay, and all patients were discharged by postoperative day 2. The patients presented with PVT at an average of 20 days (range: 10-35) post-LSG. The CT scan was positive for PVT in all patients. In stable noncirrhotic patients with nonocclusive disease, we administered therapeutic anticoagulation. One patient with high-grade, nonocclusive PVT received anticoagulation alone. Patients with occlusive disease were treated with operative thrombectomy including intraoperative and postoperative thrombolysis (tissue plasminogen

    Idiopathic cerebral sinus thrombosis (CST) can cause death and serious neurological disability. It is unknown whether smoking, a major risk factor for arterial stroke, is a risk factor also for CST. This work explored the association between smoking and CST in a hospital-based, multicentric, case-control study. In order to avoid the confounding effect of the different risk factors for CST, we analysed the homogeneous subgroup of oral contraceptive users. We compared the prevalence of smoking in a group of 43 young women with CST (cases), whose oral contraceptive use was the only known risk factor, with a sample of 255 healthy contraceptive users of similar age (controls). The prevalence of smoking in cases and controls was similar (26% vs. 29%). The age and geographic area-adjusted odds ratio was 0.9; 95% confidence interval, 0.4-1.8; p=0.7. Smoking in oral contraceptive users does not appear to be associated with CST.

    Thrombosis of fetal intracranial dural sinuses is a rare entity. A specific type of midline dural sinus thrombosis (DST) at the torcular Herophili with extension into the superior sagittal sinus (SSS) was initially seen on fetal US and was referred to fetal MRI for definite diagnosis and better delineation. Retrospective comparison to medical literature of three cases, diagnosed at our institution, of midline fetal DST with MR imaging findings and clinical outcomes. We reviewed MRI findings on T2-weighted images of our three cases of fetal midline DST and clinical outcomes of these fetuses and compared our findings to medical literature. The MR imaging and clinical findings of our cases extend over 6 years. They consist of three pregnant women, 31-39 years of age each with a single fetus, with fetal MR imaging performed at different gestational ages (GA). Case 1 the MR imaging was performed at 21 5/7 weeks' GA, case 2 at 24 and 33 4/7 weeks' GA, and case 3 at 22 and 25 weeks' GA. Postnatal MRI was performed in case 2 at 6 months of life and case 3 at 1 day of life. Clinical follow-up occurred during the last 6 years. In all of our cases, T2-W MR imaging demonstrated ballooned midline torcular Herophili with iso- to hypointense mass with or without focal eccentric area of greater hypointensity occupying the torcular Herophili with extension into the SSS. Case 3 had associated leptomeningeal dural vascular malformation overlying the left cerebral hemisphere with development of migrational disorder in the left cerebral hemisphere. Clinical outcome consisted of fetal demise in case 1, normal postnatal outcome in case 2 and severe brain damage with poor postnatal outcome in case 3. Our findings of large iso-hypointense thrombus with or without a focal eccentric area more hypointense to thrombus in a dilated torcular Herophili with extension into the SSS on T2-W images corresponds to the majority of cases of this rare type of DST in the medical literature.

    Non-traumatic cavernous internal carotid artery (ICA) aneurysms are rare, and favour the occurrence of massive recurrent epistaxis, which is associated with a high mortality rate. We report the case of a 67-year-old woman presenting a ruptured ICA aneurysm extending into the sphenoid sinus, revealed by epistaxis. Selective coil embolization of the aneurysm was performed. Flow-diverter stents were deployed in order to utterly exclude the aneurysm and prevent revascularization. Anti-platelet treatment was provided to lower the risk of in-stent thrombosis. A left frontal hematoma associated with a subarachnoid haemorrhage occurred at day 2. Outcome was favourable with no neurological sequelae, and no clinical recurrence of epistaxis occurred. A 4 months follow-up digital subtraction angiography showed a complete exclusion of the aneurysm. In addition, a magnetic resonance cerebral angiography at 16 months showed stable results. Thus, this two-stage endovascular procedure has proven its effectiveness in preventing epistaxis recurrence while preserving the ICA patency. © The Author(s) 2015.

    We report a rare case of a metastatic sphenoid sinus lesion originating from an undiagnosed hepatocellular carcinoma (HCC) in a 53-year-old man who presented with gradually progressive external ophthalmoplegia. Imaging showed a right sphenoid sinus lesion infiltrating the parasellar region. Although a primary sphenoid biopsy was inconclusive, positive hepatitis B surface antigen and CT-guided fine-needle aspiration cytology suggested an HCC. A repeat endoscopic biopsy from the sphenoid with immunohistochemistry confirmed the lesion to be metastatic HCC. Metastasis to the paranasal sinuses is extremely rare, and metastasis from a liver primary even more rare. Because of clinical and radiologic similarity between the primary and metastatic lesions, metastasis to the sphenoid sinus is often undiagnosed. Patients with features suggestive of sphenoid sinus malignancy should also be evaluated for the possibility of a metastatic tumor. In this article, we emphasize the rarity of the tumor, the unusual presenting symptoms, and problems with early diagnosis.

    Giant ovarian adenomas are rarely observed today because of early diagnosis and treatment. Mucinous cystadenomas is a kind of tumor that mostly causes the ovary to enlarge. Theu can present with various and non-specific clinical manifestations such as deep vein thrombosis. The primary symptoms of giant ovarian tumors are abdominal enlargement and distension. Therefore, making the correct preoperative diagnosis is sometimes difficult. The appropriate treatment must include oncologic procedures and a multidisciplinary approach to minimalize complications and save the patient's life. Herein, we report a woman aged 53 years with a 27-kg ovarian mucinous cystadenoma that presented as a left popliteal vein thrombosis.

    Fibro-osseous lesions of the face and paranasal sinuses are relatively uncommon. These lesions have overlapping clinical, radiologic and pathologic features causing difficulty in diagnosis. Neoplastic fibro-osseous paranasal sinus lesions can be benign or malignant. The benign fibro-osseous lesions described are: ossifying fibroma (and its histologic variants) and fibrous dysplasia. The variants of ossifying fibroma differ in the nature of calcified material (i.e. cementum versus bone), in the location of the lesion (oral versus paranasal sinus or orbital), other morphologic variations (presence of psammomatoid concretions) and biologic behavior (aggressive versus stable). Presence of cementum or bone classifies the lesion as cementifying fibroma or ossifying fibroma respectively while lesions with mixture of both cementum and bone are called cemento-ossifying fibroma. We describe a case of a young adult male with cemento-ossifying fibroma of paranasal sinus presenting acutely as left orbital cellulitis with proptosis.

    2015-01-01

    Full Text Available Inferior vena cava atresia (IVCA is a rare but well described vascular anomaly. It is a rare risk factor for deep venous thrombosis (DVT, found in approximately 5% of cases of unprovoked lower extremity (LE DVT in patients <30 years of age. Affected population is in the early thirties, predominantly male, often with a history of major physical exertion and presents with extensive or bilateral DVTs. Patients with IVC anomalies usually develop compensatory circulation through the collateral veins with enlarged azygous/hemizygous veins. Despite the compensatory circulation, the venous drainage of the lower limbs is often insufficient leading to venous stasis and thrombosis. We describe a case of extensive and bilateral deep venous thrombosis following physical exertion in a thirty-six-year-old male patient with incidental finding of IVCA on imaging.

    Full Text Available Abstract Background Solitary involvement of the sphenoid sinus has rarely been reported in non-Hodgkin's lymphoma. Isolated oculomotor nerve palsy is uncommon as an initial presentation of malignant tumors of the sphenoid sinus. Case presentation A 53-year-old woman presented with a three-month history of headache and diplopia. Neurological examination revealed complete left oculomotor nerve palsy. Magnetic Resonance Imaging (MRI demonstrated a homogenous soft-tissue lesion occupying the left sphenoid sinus and invading the left cavernous sinus. The patient underwent transsphenoidal biopsy and the lesion was histologically diagnosed as non-Hodgkin's lymphoma, diffuse large B-cell type. Tumor cells were positive for CD20 and negative for CD3. Following six cycles of chemotherapy, the left oculomotor nerve palsy that had been previously observed was completely resolved. There was no enhancing lesion noted on follow-up MRI. Conclusion It is important to recognize that non-Hodgkin's lymphoma of the sphenoid sinus can present with isolated oculomotor nerve palsy, although it is extremely rare. The cranial nerve deficits can resolve dramatically after chemotherapy.

    Dermoid cysts, encephaloceles, and dermal sinus tracts represent abnormalities that develop during the process of embryogenesis. The elucidation of the precise timing of formation for these malformations has remained elusive at the molecular level of study. Yet, clinical experience has demonstrated that these malformations do not all occur in the same patient, suggesting a shared pathway that goes awry at distinct points for different patients, resulting in 1 of the 3 malformations. Herein the authors describe a case in which all 3 malformations were present in a single patient. This is the first description in the English literature of a sincipital encephalocele occurring with a dermoid cyst and a dermal sinus tract.

A 3-year-old CF patient presented for evaluation with complaints of chronic periocular erythema, conjunctival injection, and irritation for 2 years. He was treated for presumed allergic conjunctivitis with no improvement and continued to have overall worsening of symptoms on the right greater than the left eye in a waxing and waning pattern. On presentation to the Bascom Palmer Eye Institute, he was noted to have telecanthus and prominent erythema in the region of the medial canthus. Orbital imaging disclosed a mucocele in the right ethmoid sinus. The patient underwent functional endoscopic sinus surgery, with successful marsupialization of the ethmoidal mucocele, which was found on culture to be infected with E. coli. Post-operatively with continuous pulmonary care, the patient remains free of allergic conjunctivitis and E. coli colonization of the upper airway. This case highlights the importance of analyzing the adjacent sinus in patients with chronic, relapsing allergic conjunctivitis refractory to medical management, particularly in patients with underlying systemic diseases such as CF.Keywords: allergic conjuncitivitis, Escherichia Coli, cystic fibrosis, mucocele

    2013-01-01

    Full Text Available We illustrate a case involving a 51-year-old man who presented to a tertiary hospital with sepsis secondary to an abscess of the nasal vestibule and pustular eruptions of the nasal mucosa. Associated cellulitis extended across the face to the eye, and mucosal thickening of the sinuses was seen on computed tomography. The patient underwent incision and drainage and endoscopic sinus surgery. Blood cultures and swabs were positive for a gram-negative bacillus, Burkholderia pseudomallei. He had multiple risk factors including travel to an endemic area. The patient received extended antibiotic therapy in keeping with published national guidelines. Melioidosis is caused by Burkholderia pseudomallei, found in the soil in Northern Australia and Asia. It is transmitted via cutaneous or inhaled routes, leading to pneumonia, skin or soft tissue abscesses, and genitourinary infections. Risk factors include diabetes, chronic lung disease, and alcohol abuse. It can exist as a latent, active, or reactivated infection. A high mortality rate has been identified in patients with sepsis. Melioidosis is endemic in tropical Northern Australia and northeastern Thailand where it is the most common cause of severe community-acquired sepsis. There is one other report of melioidosis in the literature involving orbital cellulitis and sinusitis.

    A 19-year-old women presented with a lytic lesion in the sacrum, associated with pain. Sinus histiocytosis (Rosai-Dorfman disease) was not diagnosed correctly until a biopsy specimen of an enlarged cervical lymph node showed the changes typical of sinus histiocytosis with massive lymphadenopathy. The disease was persistent in the patient and eventually involved the sternum. The patient improved with steroid therapy. The clinical, radiological and pathological aspects of this entity were discussed. It was stressed that radiologists, orthopedic surgeons and pathologists must be aware that sinus histiocytosis with massive lymphadenopathy may manifest initially as a bone 'tumor'.

    Full Text Available Abstract Introduction Adrenocortical carcinomas are rare aggressive tumors. Their annual incidence is approximately one to two per million among the population of the United States of America. Patients with active endocrine tumors often present with Cushing's syndrome accompanied by virilizing features. Conversely, patients with non-functioning tumors may present with symptoms related to a mass-occupying lesion, such as abdominal pain and flank pain. Although varicoceles and acute kidney injuries are common problems in medicine, they are uncommon presentations of these rare tumors and easy to miss. We report a case of a large adrenocortical carcinoma that presented as testicular pain, varicocele, and acute kidney injury secondary to renal vein thrombosis. Case presentation A 54-year-old Caucasian man with a left-sided varicocele presented to our emergency department with lower abdominal pain and a decrease in urination. Four months previously, he had noticed pain and swelling in his left groin and had been diagnosed with left-sided varicocele. For one week, he began developing left-sided abdominal pain and decreased urination frequency, so he came to our emergency department for evaluation. His physical examination revealed a hard mass occupying the entire left side of his abdomen, crossing the midline, and extending to the pelvic brim. His blood tests showed acute kidney injury and mild anemia. Computed tomography of his abdomen showed a large retroperitoneal mass on the left side, displacing the left kidney inferiorly and the spleen superiorly with thoracic epidural compression. Thrombus was also identified in his left renal vein and inferior vena cava. Computed tomography of his chest showed bilateral pulmonary nodules. A computed tomography-guided abdominal mass biopsy was performed, and the diagnosis of adrenocortical carcinoma was made on the basis of pathology and immunohistochemistry. His hormonal evaluations were normal. His kidney

    Filling defects of dural venous sinuses are considered to be a challenging problem especially in case of symptomatic patients. Many lesions have to be ruled out such as sinus thrombosis, arachnoid granulations and tumours. Encephalocele into dural sinus is also a rare cause of these filling defects of dural sinuses. Here, we report an extremely rare case with spontaneous occult invagination of temporal brain tissue into the left sigmoid sinus and accompanying cerebellar ectopia. PMID:24311424

    Nonosseous or soft tissue Ewing's sarcoma is a rare form of Ewing's sarcoma/primitive neuroectodermal tumour that seldom affects the head and neck region. Involvement of the nose and paranasal sinuses is extremely uncommon, with only eight of such patients being reported to date, mostly affecting adolescents and young adults. To our knowledge, this study is the first comprehensive report of primary soft tissue Ewing's sarcoma involving the paranasal sinuses in an elderly patient who successfully completed treatment. We herein discuss the pathogenesis, management and factors affecting the prognosis of this rare group of tumours involving the nose and paranasal sinuses, in relation to the available literature.

  13. Doping and thrombosis in sports.

    Historically, humans have long sought to enhance their "athletic" performance to increase body weight, aggressiveness, mental concentration and physical strength, contextually reducing fatigue, pain, and improving recovery. Although regular training is the mainstay for achieving these targets, the ancillary use of ergogenic aids has become commonplace in all sports. The demarcation between ergogenic aids and doping substances or practices is continuously challenging and mostly based on perceptions regarding the corruption of the fairness of competition and the potential side effects or adverse events arising from the use of otherwise unnecessary ergogenic substances. A kaleidoscope of side effects has been associated with the use of doping agents, including behavioral, skeletal, endocrinologic, metabolic, hemodynamic, and cardiovascular imbalances. Among the various doping substances, the most striking association with thrombotic complications has been reported for androgenic anabolic steroids (i.e., cardiomyopathy, fatal and nonfatal arrhythmias, myocardial infarction [MI], intracardiac thrombosis, stroke, venous thromboembolism [VTE], limb arterial thrombosis, branch retinal vein occlusion, cerebral venous sinus thrombosis) and blood boosting (i.e., VTE and MI, especially for epoetin and analogs). The potential thrombotic complication arising from misuse of other doping agents such as the administration of cortisol, growth hormone, prolactin, cocaine, and platelet-derived preparations is instead speculative or anecdotal at best. The present article provides an overview on the epidemiological association as well as the underlying biochemical and biological mechanisms linking the practice of doping in sports with the development of thrombosis. © Thieme Medical Publishers.

  14. Endoscopic endonasal repair of spontaneous sphenoid sinus lateral wall meningocele presenting with cerebrospinal fluid leak

    Full Text Available Spontaneous sphenoid sinus lateral wall meningoceles are rare lesions with an unknown etiology. Endoscopic endonasal technique is a considerable route in the treatment of this condition. The aim of this paper is to report the etiology, surgical technique, and outcome in a patient repaired via endoscopic endonasal approach. A 51-year-old male patient applied with rhinorrhea started three months ago after an upper respiratory infection. There were no history of trauma or sinus operation. Biochemical analysis of the fluid was positive for beta-2-transferrin. This asypthomatic patient had undergone for repairment of lateral sphenoid sinus meningocele with endoscopic endonasal transsphenoidal approach. After endoscopic endonasal meningocele closure procedure no complications occured and a quick recovery was observed. Endoscopic endonasal approach is an effective and safe treatment modality of spontaneous lateral sphenoid sinus meningoceles and efficient in anterior skull base reconstruction.

    Behçet's disease (BD) is a multisystem disorder. The main pathology in BD is vasculitis that involves arteries and veins of all calibers. Central nervous system involvement occurs in 5-10% of patients. Increased morbidity and mortality is rarely observed in children. The mean age at onset in pediatric BD is approximately 7 years. Neurologic involvement in BD is usually observed after 3-6 years. We report the case of a four-year-old Turkish boy with BD with sagittal sinus thrombosis treated with infliximab. The patient presented papilledema without neurologic signs. Although long-term efficacy evaluations are needed in this case, infliximab therapy may be a good option in childhood BD with refractory sinus thrombosis. This is the youngest case of BD with sagittal sinus thrombosis reported so far. Copyright © 2012 Elsevier España, S.L. All rights reserved.

  16. Superior Vena Cava Syndrome due to Thrombosis: A Rare Paraneoplastic Presentation of Bronchogenic Carcinoma

    2016-07-01

    Full Text Available Superior vena cava (SVC syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable state, e.g., malignancy. Here, an unusual case of sudden onset SVC syndrome has been reported, which on initial radiologic evaluation was found to have a lung nodule without any significant mediastinal mass or adenopathy compressing SVC. Subsequent investigation with Doppler ultrasonography of the neck showed thrombosis in the right internal jugular, right subclavian and right brachiocephalic vein, which was responsible for SVC syndrome. Histopathological evaluation of lung nodule confirmed presence of an adenocarcinoma. Therefore, venous thromboembolism as a paraneoplastic syndrome should be kept in mind while evaluating a case of SVC obstruction in a cancer patient. Management of the underlying disease is of prime importance in such cases and anticoagulation is the mainstay of therapy. Ability to identify paraneoplastic syndrome may have a significant effect on clinical outcome, ranging from early diagnosis to improved quality of life of the patient.

    A combination of giant hepatic hemangioma and diffuse hemangiomatosis is extremely rare in adults. Even when they are large, hemangiomas are soft and rarely compress adjacent structures. A 78-year-old man presented with abdominal pain and distension. Ultrasonography, computed tomography, and magnetic resonance imaging demonstrated a large expansile mass replacing the medial segment and caudate lobe with diffusely scattered nodules in the entire liver. The large hilar mass contained a central nonenhancing area and had a mass effect, leading to left portal vein occlusion. The image findings also revealed two unprecedented findings: left lateral segmental atrophy of the liver and recent portomesenteric vein thrombosis. The hepatic lesions were confirmed with hemangiomas by ultrasonography-guided biopsy. We diagnosed intrahepatic portal vein obstruction caused by a mass effect of giant hepatic hemangioma coexistent with diffuse hemangiomatosis, resulting in hepatic segmental atrophy and extrahepatic portal vein thrombosis.

    Mucoceles are cystic masses that generally affect the sinuses. It occurs as a result from obstruction of the ostium of a sinus and consequential accumulation of mucus. Frontal and ethmoid sinuses are mostly affected. Usually, the clinical symptoms are insidious, varying with the extent of the affected region. The treatment is surgical and endoscopic surgery is the method of choice in most cases. The present study is aimed at describing the main characteristics of paranasal sinuses mucoceles, demonstrating and illustrating a series of atypical presentations with emphasis on imaging findings.

    Cerebral venous thrombosis (CVT) is an infrequent illness, although more than one hundred possible causes have been described. These causes can be divided In two categories: local ones and systemic ones. Magnetic resonance is the most sensitive non invasive method to diagnose CVT. This article presents cases of dural sinus thrombosis, reported in the Clinic Reina Sofia between June of 2003 and June of 2004. Fifteen cases were found. The principle symptoms were: headache, convulsions, and focal neurological deficit. The more frequently affected venous sinus were the transverse and the superior sagittal ones

    There are only a few reports of patients developing cerebral venous sinus thrombosis (CVST) after androgen therapy. We present a young man who developed cortical venous thrombosis after using androgens to increase muscle mass. He was hospitalised for parasthesia and dyspraxia in the left hand followed by a generalised tonic-clonic seizure. At admission, he was drowsy, not fully orientated, had sensory inattention, pronation drift and a positive extensor response, all on the left side. The patient had been using anabolic steroids (dainabol 20 mg/day) for the last month for bodybuilding. CT angiography showed a right cortical venous thrombosis. Anticoagulation therapy was started with intravenous heparin for 11 days and oral anticoagulation (warfarin) thereafter. A control CT angiography 4 months later showed resolution of the thrombosis. He recovered fully.

    Chronic heart failure (HF) with either reduced or preserved ejection fraction is common and remains an extremely serious disorder with a high mortality and morbidity. Many complications related to HF can be related to thrombosis. Epidemiological and pathophysiological data also link HF to an increased risk of thrombosis, leading to the clinical consequences of sudden death, stroke, systemic thrombo-embolism, and/or venous thrombo-embolism. This consensus document of the Heart Failure Association (EHFA) of the European Society of Cardiology (ESC) and the ESC Working Group on Thrombosis reviews the published evidence and summarizes 'best practice', and puts forward consensus statements that may help to define evidence gaps and assist management decisions in everyday clinical practice. In HF patients with atrial fibrillation, oral anticoagulation is recommended, and the CHA(2)DS(2)-VASc and HAS-BLED scores should be used to determine the likely risk-benefit ratio (thrombo-embolism prevention vs. risk of bleeding) of oral anticoagulation. In HF patients with reduced left ventricular ejection fraction who are in sinus rhythm there is no evidence of an overall benefit of vitamin K antagonists (e.g. warfarin) on mortality, with risk of major bleeding. Despite the potential for a reduction in ischaemic stroke, there is currently no compelling reason to use warfarin routinely for these patients. Risk factors associated with increased risk of thrombo-embolic events should be identified and decisions regarding use of anticoagulation individualized. Patient values and preferences are important determinants when balancing the risk of thrombo-embolism against bleeding risk. New oral anticoagulants that offer a different risk-benefit profile compared with warfarin may appear as an attractive therapeutic option, but this would need to be confirmed in clinical trials.

    Full Text Available Headache is a common occurrence during pregnancy. A postural headache is invariably considered to be a postdural puncture headache in patients who receive neuraxial anesthesia with or without obvious or incidental dural puncture. Cerebral venous thrombosis (CVT is rare in pregnancy and in the postpartum period, with an incidence of 1:10,000–1:25,000. Pregnancy-induced changes in coagulation result in a hypercoagulable state, which may naturally reduce the incidence of postpartum hemorrhage, but may also increase the risk of CVT. Postpartum headache being frequently encountered may complicate the diagnosis of CVT. We report a case of a woman who developed a postpartum CVT after an accidental wet tap and intrathecal catheter placement during labor.

    Vascular manifestations including pulmonary artery aneurysms and venous thrombosis are seen in up to 14% of patients with Behcet's disease. We report a patient who had recurrent deep vein thrombosis (DVT) as the presenting symptom of Behcet's Disease. A 19-year-old male who presented with acute iliofemoral DVT, confirmed by intravascular ultrasound (IVUS) and venogram. May-Thurner syndrome was also observed. Repeated catheter-based pharmacomechanical thrombolysis, thrombectomy, and subsequent iliac vein stenting were performed. The patient was then discharged on rivaroxaban and aspirin. Five months later, the patient experienced left calf pain. In the interim, he had been diagnosed with Behcet's disease by a rheumatologist who was consulted due to oral ulcers and skin lesions and accordingly started on prednisone, colchicine, and azathioprine. At this time, IVUS and venogram revealed thrombotic occlusion of the previously placed stent. Tissue plasminogen activator was infused into the stent, and pharmacomechanical thrombectomy restored flow through the left iliac veins. Follow-up laboratory workup revealed that subtherapeutic azathioprine dosing, and after appropriate adjustment, the patient has been asymptomatic for 12 months. Acute refractory DVT is a possible presenting symptom of Behcet's disease, which may be complicated by May-Thurner syndrome. Such patients should receive therapeutic immunosuppression in addition to anticoagulation. Copyright © 2018 Elsevier Inc. All rights reserved.

    Venous thromboembolism (VTE), a disease entity comprising deep vein thrombosis (DVT) and pulmonary embolism (PE), is a frequent and potentially life-threatening event. To date different agents are available for the effective treatment of acute VTE and the prevention of recurrence. For several years, the standard of care was the subcutaneous application of a low molecular weight heparin (LMWH) or fondaparinux, followed by a vitamin K antagonist (VKA). The so-called direct oral anticoagulants (DOAC) were introduced rather recently in clinical practice for the treatment of VTE. DOAC seem to have a favorable risk-benefit profile compared to VKA. Moreover, DOAC significantly simplify VTE treatment because they are administered in fixed doses and no routine monitoring is needed. Patients with objectively diagnosed DVT or PE should receive therapeutic anticoagulation for a minimum of 3 months. Whether a patient ought to receive extended treatment needs to be evaluated on an individual basis, depending mainly on risk factors determined by characteristics of the thrombotic event and patient-related factors. In specific patient groups (e.g., pregnant women, cancer patients, and elderly patients), treatment of VTE is more challenging than that in the general population and additional issues need to be considered in those patients. The aim of this review is to give an overview of the currently available treatment modalities of acute VTE and secondary prophylaxis. In particular, specific aspects regarding the initiation of VTE treatment, duration of anticoagulation, and specific patient groups will be discussed.

    To determine the prevalence of arterial stump thrombosis (AST) after pulmonary resection surgery for lung cancer and to describe subsequent radiological follow-up and treatment. Observational, descriptive study of AST detected by computerized tomography angiography (CT) using intravenous contrast. Clinical and radiological variables were compared and a survival analysis using Kaplan-Meier curves was performed after dividing patients into 3 groups: patients with AST, patients with pulmonary embolism (PE), and patients without AST or PE. Nine cases of AST were detected after a total of 473 surgeries (1.9%), 6 of them in right-sided surgeries (67% of AST cases). Median time to detection after surgery was 11.3 months (interquartile range 2.7-42.2 months), and range 67.5 months (1.4-69.0 months). Statistically significant differences were found only in the number of CTs performed in AST patients compared to those without AST or PE, and in tumor recurrence in PE patients compared to the other 2 groups. No differences were found in baseline or oncological characteristics, nor in the survival analysis. In this series, AST prevalence was low and tended to occur in right-sided surgeries. Detection over time was variable, and unrelated to risk factors previous to surgery, histopathology, and tumor stage or recurrence. AST had no impact on patient survival. Copyright © 2016 SEPAR.

    Full Text Available A middle-aged hypertensive male, with a fatty liver and chronic alcohol intake, relocated to a high altitude of 2100 m above sea level; in the first winter season, he developed bluish skin lesions over the tip of the nose, margins of both ear lobes, both knees, and subungual location. Systemic examination was unremarkable. Skin biopsy showed thrombi in dermal vessels without any evidence of vasculitis; immunofluorescence was negative. Investigations revealed mild elevation in plasma homocysteine levels, weakly positive antinuclear antibodies and elevated antiphospholipid antibodies, methylene tetrahydrofolate reductase C677T heterozygosity, and protein S deficiency. The patient received prednisolone for 2 weeks, aspirin and pentoxyphylline for 3 months, and continues to be on folic acid and vitamin B6. After 3 months, antiphospholipid antibodies and antinuclear antibody levels were normal. Isolated distal cutaneous thrombosis is an uncommon entity and precipitation by extreme cold in a hypertensive male with three thrombophilic states - one transient, one hereditary, and one acquired - is fascinating.

    Full Text Available Sinonasal undifferentiated carcinoma-related rhinogenic optic neuropathy is rare and may lead to visual loss. To the best of our knowledge, this is the first report of bilateral sequential visual loss induced by this etiology. It is important to differentiate between chronic sinusitis and malignancy on the basis of specific findings on magnetic resonance images. Surgical decompression with multidisciplinary therapy, including steroids, chemotherapy, and radiotherapy, is indicated. However, no visual improvement was noted in this case, emphasizing the rapid disease progression and importance of early diagnosis and treatment.

    We report a case of a 56-year-old man referred by his family physician with an asymptomatic cardiac murmur. Trans-thoracic echocardiography (TTE) suggested an unruptured right sinus of Valsalva aneurysm (SVA) causing extrinsic compression of the right ventricular outflow tract. This was confirmed with an ECG-gated cardiac CT showing a large right SVA measuring 35×37×42 mm in size. Coronary angiography demonstrated non-obstructive coronary artery disease. Ascending thoracic anterior in the right anterior oblique view delineated the right SVA. The patient underwent aortic valve sparing surgical repair of the aneurysm with an excellent result. Echocardiography confirmed obliteration of the aneurysm and normal aortic valve function postoperatively.

    Pott's puffy tumor is a rare complication of frontal sinusitis characterized by swelling and edema in the brow due to a subperiosteal abscess associated with frontal osteomyelitis. Added complications are cellulitis by extension to the orbit and intracranial infection by posterior extension, with high risk of meningitis, intracranial abscess, and venous sinus thrombosis. Early diagnosis and aggressive medical or surgical treatment are essential for optimal recovery of affected patients. In the antibiotic age it is extremely rare, with very few cases described in the recent literature. A case is presented of a Pott inflammatory tumor in a 7 year-old boy, as a complication of acute pansinusitis who presented with front preseptal swelling and intracranial involvement with thrombosis of ophthalmic and superior orbital veins and frontal epidural abscess extending to the subarachnoid space.

    The pathogenesis of acute thrombosis, either arterial or venous, is typically multifactorial and involves a variety of factors that may be considered relatively "innocuous" when present alone. When someone is unlucky enough to accumulate several risk factors, compounded in many cases by one or more acute triggers, that person may be propelled over a threshold that precipitates the development of an acute episode of thrombosis. There is now reliable evidence that acute thromboses (both venous thromboembolism and acute coronary syndrome) follow a typical seasonal pattern and particularly display a characteristic spike during holiday periods. Overindulgence and abrupt changes of several lifestyle habits have been described as potential precipitating factors during such periods. Long travels, unhealthy diet, excessive or binge drinking and eating, decreased or increased physical activity, emotional and psychological stress, might all variably contribute to trigger an acute thrombotic event. Although the real causes of this "holiday phenomenon" remain speculative as yet, there is a widespread perception that they might represent preventable events like several other risk factors of both venous and arterial thrombosis. Beside drastic and unrealistic measures, such as canceling such holidays from the calendar, it seems reasonable to at least provide advice to patients about these "dangers," especially those individuals believed to be carrying a higher risk. Many (if not all) patients may ignore such advice and carry on regardless, but they should be given the benefit of informed choice. © Thieme Medical Publishers.

    Full Text Available La sinusitis aguda es un proceso inflamatorio de la mucosa de los senos paranasales, de etiología bacteriana principalmente. Es más frecuente en las edades escolares y en las épocas de mayor circulación de los virus respiratorios. Se desarrolla cuando se afecta el drenaje normal de los senos y se retienen las secreciones mucosas. Las complicaciones más severas, como celulitis y abscesos periorbitarios, son raras. La celulitis orbitaria es una entidad poco frecuente, cuya importancia radica en que puede asociarse a la pérdida de la visión y otras complicaciones. Se presenta el caso de un paciente de 6 años, afectado con celulitis orbitaria, secundaria a sinusitis, y se comentan las peculiaridades del diagnóstico y el tratamiento, con el objetivo de alertar al pediatra para su diagnóstico temprano, lo que optimizaría su tratamiento.The acute sinusitis is a inflammatory process of the mucosa of paranasal sinuses, the more important bacterial etiology. It is more frequent in the school ages and in the periods of more circulation of the respiratory viruses, which develops when the normal drainage of the sinuses is involved and there is retention of the mucosa secretions. The more severe complications including cellulitis and periorbital abscesses are rare. The orbital cellulitis is an entity not much frequent, whose significance lie in it may be associated to loss of vision and other complications. Authors present the case of a patient aged 6 presenting with orbital cellulitis, secondary to sinusitis and the particular feature of diagnosis and treatment to alert pediatrician for its early diagnosis, optimizing its treatment.

    BACKGROUND Acute coronary syndrome (ACS) can present with atypical chest pain or symptoms not attributed to heart disease, such as indigestion. Hiccups, a benign and self-limited condition, can become persistent or intractable with overlooked underlying etiology. There are various causes of protracted hiccups, including metabolic abnormalities, psychogenic disorders, malignancy, central nervous system pathology, medications, pulmonary disorders, or gastrointestinal etiologies. It is rarely attributed to cardiac disease. CASE REPORT We report a case of intractable hiccups in a 51-year-old male with cocaine related myocardial infarction (MI) before and after stent placement. Coronary angiogram showed in-stent thrombosis of the initial intervention. Following thrombectomy, balloon angioplasty, and stent, the patient recovered well without additional episodes of hiccups. Although hiccups are not known to present with a predilection for a particular cause of myocardial ischemia, this case may additionally be explained by the sympathomimetic effects of cocaine, which lead to vasoconstriction of coronary arteries. CONCLUSIONS Hiccups associated with cardiac enzyme elevation and EKG ST-segment elevation before and after percutaneous coronary intervention (PCI) maybe a manifestation of acute MI with or without stent. The fact that this patient was a cocaine user may have contributed to the unique presentation.

    We describe the case of a man aged 43 years who presented with a 2-week history of a palpable lump in the right proximal penile shaft. This was preceded by a 6-month history of perineal pain, accompanied by erectile dysfunction. An urgent MRI scan of his penis identified a thrombus within the right crus and corpus of the penis. His thrombophilia screen was normal. The patient was started on oral anticoagulation and a phosphodiesterase inhibitor (PDE-5i) to prevent thrombus progression and maintain erectile function. At 5 months, the patients' symptoms had resolved and an MRI showed a reduction in the thrombus size. MRI is a useful imaging modality to diagnose a thrombus within the corpus cavernosum in patients presenting with a history of penile and perineal pain together with a palpable lump. The non-enhancement of the lesion helps to differentiate this from alternative rare lesions within the penis and perineum. 2016 BMJ Publishing Group Ltd.

    There is an important link between platelets and inflammation, thrombosis, and vascular and tissue repair mechanisms. SCUBE1 (signal peptide-CUB-EGF domain-containing protein 1) may function as a novel platelet-endothelial adhesion molecule and play pathological roles in cardiovascular biology. Stent thrombosis (ST) following percutaneous coronary intervention is an uncommon and potentially catastrophic event that can manifest as myocardial infarction and sudden death. High platelet reactivity is a risk factor for thrombotic events, including late ST. For this reason, in the current study, we researched the role of SCUBE1 in the development of late coronary ST. We included 40 patients admitted to our hospital with a diagnosis of ST-elevation myocardial infarction (STEMI) and signs of late ST on a coronary angiogram. For the control group, we recruited 50 healthy gender- and age-matched individuals who were seen for health check-ups. We also randomly included 100 patients with a diagnosis of STEMI without ST. There were no significant differences between the groups in terms of baseline and demographic characteristics. The mean SCUBE1 level in patients with STEMI with late ST at admission and the STEMI without ST group was significantly higher than in the control group (pST group was significantly higher than in the STEMI without ST group (p=0.03). In multivariate regression analysis, serum SCUBE1 (odds ratio [OR]: 1.022; 95% confidence interval [CI]: 1.011-1.033, pST. In addition, receiver operating characteristic curve analysis was used to determine the optimal SCUBE1 cut-off value for predicting late ST. The area under the curve was 0.972 (95% CI 0.95-0.98). The SCUBE1 cut-off value was 59.2 ng/ml, with a sensitivity of 95.4% and specificity of 82.9%. The present work is the first clinical study to demonstrate that serum SCUBE1 levels are significantly higher in patients with late ST and serum SCUBE1 was an independent predictor for the presence of late ST in our

    There is a relationship between thyroid diseases and primary and secondary changes in haemostasis. The most frequent association between them are hypocoagulability states with clinical hypothyroidism and vascular thrombophilia (hypercoagulability and/or hypofibrinolysis) with hyperparathyroidism. However, there are recent studies that have detected changes in haemostasis -primary and secondary- associated with thyroid diseases with normal hormone levels, suggesting other pathogenic mechanisms not yet known. The cases are presented of 2 patients with thyroid disease that required surgery: one multinodular goitre and one papillary carcinoma of the thyroid, both with normal hormone levels. They were shown to have haemostasis disorders during the preoperative work up. These showed a Factor VII deficiency and a Factor XI deficiency along with a thrombotic disease of unknown origin, respectively.

    Lower extremity deep vein thrombosis (DVT) is a common illness with an annual incidence of 1 per 1000 adults. The major long-term complication of DVT is post-thrombotic syndrome (PTS) which occurs in up to 60% of patients within 2 years of an episode of DVT. We aim to evaluate the outcomes of catheter-directed treatment (CDT) for symptomatic acute or subacute lower extremity DVT. A retrospective 12-year study was conducted on the outcomes of CDT on 54 consecutive patients who presented with acute or subacute lower extremity DVT to our hospital. Descriptive summary statistics and the Chi-square test were used to measure the outcomes of CDT. Grade 3 thrombolysis was achieved in 25 (46.3%) patients, grade 2 thrombolysis in 25 (46.3%) patients, and grade 1 thrombolysis in 4 (7.4%) patients. Significant recanalization (grade 2 or 3 thrombolysis) was possible in 50 (92.6%) patients. There was no statistically significant difference in the percentage of significant recanalization that could be achieved between patients who underwent CDT before and after 10 days. There was no significant difference between the thrombolysis achieved between urokinase and r-tPA. PTS was seen in 33% of the patients. Major complications were seen in 5.5% of the patients. CDT is a safe and effective therapeutic technique in patients with acute and subacute lower extremity DVT, if appropriate patient selection is made.

    We studied the anatomic relationship between arachnoid granulations in the transverse sinus and the termination of the vein of Labbe in 57 consecutive angiograms. Patients with pathology in intracranial venous structures or with inadequate image quality of the venous system were excluded. Arachnoid granulations were found in 12 of the 57 patients (21.1 %), always at the junction of the vein of Labbe and the transverse sinus; the vein of Labbe was present in 55 patients (96.5 %), most often without associated arachnoid granulations; the latter, however, were not observed in the absence of a vein of Labbe. This study confirms the close, constant anatomic relationship between arachnoid granulations in the transverse sinus and the termination of the vein of Labbe. This observation may help to differentiate arachnoid granulations from pathologic conditions involving the transverse sinus such as dural sinus thrombosis. The constant character of this relationship suggests a developmental role of afferent veins in the formation of arachnoid granulations. (orig.)

    In the presence of severe sinus mucosal thickening, the ostium can be blocked when the sinus membrane is lifted, causing drainage disturbances and sinusitis. Here, we present 3 cases in which maxillary sinus floor elevation was performed using a crestal approach in the presence of severe sinus mucosal thickening (>10 mm). The effects of maxillary sinus floor elevation using the crestal approach technique on sinus mucosal thickening and bone formation in the sinus were evaluated using cone beam computed tomography. None of the patients exhibited an increase in sinus membrane thickness. No complications were encountered during the follow-up periods, and bone formation was observed around the implants at the sinus floor. All implants were functioning successfully. Maxillary sinus floor elevation using the crestal approach technique in the presence of severe sinus mucosal thickening allows for minimally invasive sinus grafting and simultaneous implant placement and does not increase sinus membrane thickness.

    Full Text Available Midline congenital malformation of the nose is a very rare presentation and it's midline situation seems curious and is very difficult to explain on the basis of the present day conception of the embryology of the nose. The prevalence of lower lip sinuses has been estimated to be about 0.001 % of the general population. Upper lip sinuses are even more uncommon. We herein report a case of a 13 years old girl having congenital sinus affecting the upper part of the columella.

    Cerebral venous thrombosis is a rare entity with widely variable clinical signs: thus, a high degree of suspicion is required for diagnosis. It affects the dural sinuses and may or may not invade cerebral veins. The diagnosis has usually been based on an angiographic study although, at the present time, new noninvasive imaging techniques, such as computed tomography, magnetic resonance and magnetic resonance angiography are being employed in a growing number of cases. Treatment should involve symptomatic and etiologic therapy. Although anti coagulation would appear to be a reasonable option in these patients, it remains controversial. As in other processes such as pulmonary embolism and coronary thrombosis, the introduction of novel and increasingly safe fibrinolytic drugs, together with technical innovations in the field of interventional neuroradiology, is changing the perspectives for the management of these patients. We present the case of a 43-year-old woman with right sinus thrombosis who was treated with local thrombolysis plus alteplase (tissue plasminogen activator). The authors describe the technique employed and review the literature. (Author) 16 refs

    Cemento-ossifying fibroma is a lesion containing both fibrous and osseous components. Such lesions include fibrous dysplasia, ossifying fibroma, cemento-ossifying fibroma and cementifying fibroma. Periodontal membrane is the origin of fibro-osseous lesions other than fibrous dysplasia.Here a clinical case of a young woman referred for evaluation of a mass in the right side of face between eye and nose is presented. The first time she noticed the mass was 2 years ago and was growing larger inwards. She was treated with surgical resection.In this case of a cemento-ossifying fibroma, histological interpretation was critical, and was the basis of correct treatment.

    Full Text Available Systemic lupus erythematosus (SLE, is sometimes complicated by the rare fatal syndrome, Thrombotic thrombocyto-penic purpura (TTP, but the occurrence of TTP as the initial manifestation of SLE is very rare. Since they have similar-ities in some features, the differentiation of TTP from SLE may be missed. SLE patients are also more prone to throm-botic events. Here we report a case with TTP and deep vein thrombosis as the presenting symptoms of SLE.

    To analyze the radiologic-especially angiographic-findings of deep seated cerebral arteriovenous malformation(AVM) involving nonvisualized straight sinus. In six patients aged between 15 and 53 years with deep seated cerebral AVM, CT and MR images were retrospectively analyzed with regard to the following features : the presence of straight sinus, the location of AVM, and the occurrence of hemorrhage. Angiograms were analyzed for venous drainage routes of AVM, the appearance of veins, the presence of falcine sinus and venous drainage from normal deep brain parenchyme. In four patients who had undergone intravascular embolization therapy, pre- and post- embolization angiograms were compared. CT and MR images showed neither straight sinus nor thrombosis. AVMs were deeply seated in the brain, and in all cases there was cerebral hemorrhage. Angiograms disclosed that venous drainage of all AVMs occurred via the veins of Galen. In one case, venous flow via the falcine sinus to the superior sagittal sinus was noted, but in others, retrograde flow in the deep venous system was observed. Marked collateral routes followed in response to the obstruction of straight sinus included the basal vein of Rosenthal, the internal occipital, internal cerebral, and cerebellar hemispheric veins (which are Galenic afferents), and the inferior sagittal sinus. In all patients, contralateral routes were partially involved. Venous drainage from normal deep parenchyme through the transcerebral veins to the superficial venous system was noted, and in one case, straight sinus which had been observed on an angiogram five years earlier was no longer present. Angiography offers effective evaluation of the dynamic aspect of venous flow in cases involving deep-seated AVM, and of normal deep parenchyme in cases in which AVM involves nonvisualized straight sinus. Before intravascular treatment of AVM, venous flow must be carefully analyzed

    Fungal paranasal sinusitis is included in the differential diagnosis of unilateral paranasal lesion. Recently the incidence of fungal paranasal sinusitis has been increasing. We reviewed 24 patients (9 males and 15 females) with fungal paranasal sinusitis treated at Muroran City Hospital between January 2001 and May 2006, and clinical presentation and CT findings with those of 56 patients (36 males and 20 females) with chronic unilateral sinusitis. Fungal sinusitis patients ranged in age from 45 to 87, and the average age was 65.9 years old. In contrast, the age of chronic sinusitis patients ranged from 24 to 83, and the average age was 54.4 years old. The chief complaint of both fungal sinusitis and chronic sinusitis included rhinorrhea, nasal obstruction and post nasal discharge. CT exam was performed in all patients. In 23 cases of paranasal fungal sinusitis and 54 cases of chronic sinusitis the findings involved the maxillary sinus. The most common observation (69.6%) was bone density within the affected sinus in fungal sinusitis. However, only 2 cases of chronic sinusitis (3.9%) showed calcification. All cases of fungal sinusitis were diagnosed by pathological examinations. Most cases were proved to be aspergillus, while only one case was mucor. We treated all cases surgically, 18 cases underwent Caldwell-Luc's procedure and 5 cases underwent endoscopic sinus surgery under local anesthesia. (author)

    The primitive tentorial, occipital, and falcine sinuses are thought to attain the adult pattern or regress between the fetal stage and adulthood. The anatomy of these three primitive dural sinuses has seldom been studied in the infant population, and it remains unclear when these dural sinuses reach the adult condition. Using computed tomography digital subtraction venography (CT-DSV), we analyzed the anatomy of these embryonic dural sinuses in infants. We included 13 infants who underwent CT-DSV prior to neurosurgery and 35 cases with unruptured cerebral aneurysms as normal adult controls. Three embryonic dural sinuses, i.e., the primitive tentorial, occipital, and falcine sinuses, were retrospectively analyzed in CT-DSV images of infants and adults. We also analyzed the drainage patterns of the superficial middle cerebral vein (SMCV), determined by the connection between the primitive tentorial sinus and the cavernous sinus. The primitive tentorial, occipital, and falcine sinuses were present in 15.4%, 46.2%, and none of the infants, respectively, and in 10.0, 8.6, and 2.9% of the adults, respectively. The difference in SMCV draining pattern between infants and adults was insignificant. The incidence of the occipital sinus was significantly higher in infants than in adults. The connection between the primitive tentorial sinus and the cavernous sinus appears to be established before birth. The occipital sinus is formed at the embryonic stage and mostly regresses after infancy. The falcine sinus is usually obliterated prenatally. Our findings form the basis for interventions by pediatric interventional neuroradiologists and neurosurgeons.

    An encephalocele is a protrusion of the cranial contents beyond the normal confines of the skull. It is a rare cause of seizure in adults. A 38-year-old woman presented with a first-onset seizure. Brain CT was interpreted as right frontal sinus opacification suggestive of sinusitis. The patient was discharged home with an amoxicillin prescription. A few days later, she was re-admitted with another seizure. Careful evaluation of the brain CT and MRI revealed a right frontal sinus posterior wall defect and possible brain encephalocele. The patient had complained of chronic nasal discharge for years and had also noticed a watery discharge from her right nostril. We suspected cerebrospinal fluid rhinorrhea. A bifrontal craniotomy was performed, the encephalocele was resected and cranialisation of the frontal sinus was completed. The patient remained free of seizures at the last follow-up. PMID:23188840

    The sphenoid sinus is the least common site of mucocele of all paranasal sinuses. It is very rare in children, especially in those younger than 12 years when pneumatization of the sphenoid sinus is completed. We report a case of histologically proven sphenoidal mucocele in a 5-year-old child. The child presented with an acute onset of significant visual impairment and headache. His vision gradually improved after trans-nasal sphenoidotomy and drainage of the sinus content with return of complete normal baseline vision after 2 months. (orig.)

    Objective: To explore the relation between venous sinus stenosis and pseduotumour cerebri and to discuss the efficacy and strategy of venous sinus stenting for its treatment. Methods: Venous sinus stenting was performed in a total of 9 patients with pseudotumour cerebri accompanied by dural sinus stenosis. The clinical data, including the clinical presentations, intracranial pressure, angiographic findings, pressure of dural sinus,methods of treatment and the therapeutic results, were retrospectively analyzed. Results: Bilateral disc edema was seen in all patients. The pressure gradient in the lateral sinuses was obviously high before stenting (22.67±7.25)mmHg in all patients and a reduction in intra-sinus pressure and pressure gradient was also found (5.78±3.77)mmHg. The symptoms associated with intracranial hypertension were gradually improved or disappeared in two weeks after the placement of the stent in all cases, and the intracranial pressure dropped evidently (12.78±5.97)cm H 2 O. Vision was improved in 7 cases at three months, whereas it remained poor in 2 cases despite normalized intracranial pressure. There was no other permanent procedure-related morbidity. The patients were followed up for 3 months to 5 years, and no recurrence developed. Conclusion: Lateral sinus stenting is an effective method for the treatment of pseudotumour cerebri with dural sinus stenosis. (authors)

    Headache happens in the majority of patients with Cerebral Venous Thrombosis (CVT) being sometimes the sole manifestation of the disease. Herein we report a case-series of CVT, focusing on headache characteristics. Etiological, clinical, and radiological features of 25 consecutive adult patients with CVT were compiled from August 2005 to December 2013. Diagnosis of CVT was confirmed by brain magnetic resonance imaging and magnetic resonance venography. All patients underwent extensive systematic etiological and genetic work-up at admission. A structured questionnaire about the characteristics of headache was responded by all participants. Headache was reported by 23 out of 25 (92%) of participants, being by far the most frequent symptom. It was the sole manifestation in nearly one third of the patients (8/25, 32.0%). Headache was typically severe (19/23, 82.6%) and throbbing (16/23, 69.5%), with sudden onset (13/23, 56.5%) and non-remitting (20/23, 86.9%) characteristics. The sinus most frequently involved was the transverse sinus (24/25, 96.0%), either alone or in association with other sinuses. Headache is the most frequent symptom and sometimes the sole presentation of CVT. © 2015 American Headache Society.

    Ovarian vein thrombosis is a rare postpartum complication (0.1%). It can be fatal, since it can lead to sepsis, pulmonary thromboembolisms and inferior vena cava or renal vein thrombosis. Computed tomography and magnetic resonance imaging are the techniques of choice for its diagnosis, while the value of ultrasound is limited due to its low sensitivity and specificity. We report the case of a woman who, during puerperium, developed thrombosis of right ovarian vein that presented clinical, ultrasonographic and computed tomographic features of appendicitis. We describe the radiological sings and stress the fact that this diagnosis should be suspected in puerperal women. (Author) 9 refs

    Full Text Available Lemierre’s syndrome is also known as postangina septicemia, which is commonly caused by Fusobacterium necrophorum also known as Necrobacillus and also by other microorganisms like Staphylococcus, Streptococcus, Peptostreptococcus, and Bacteroides. Though the disease starts as an upper respiratory tract infection, it may spread and cause thrombophlebitis of the internal jugular vein. It may present itself through cranial nerve palsy or sepsis involving distant organs like the lungs or bones. It is also known as forgotten disease because of its rarity. Fusobacterium necrophorum usually causes infection in animals and rarely affects humans. We hereby present a case of Necrobacillus infection which did not cause any thrombophlebitis but resulted in severe pneumonia and acute kidney injury, leading to respiratory failure and requiring mechanical ventilation.

    Full Text Available Portal vein thrombosis is an important cause of presinusoidal portal hypertension. Portal vein thrombosis commonly occurs in patient with cirrhosis, malignancy and prothrombotic states. Patients with acute portal vein thrombosis have immediate onset. Patients with chronic portal vein thrombosis have developed portal hypertension and cavernous portal transformation. Portal vein thrombosis is diagnosed with doppler ultrasound, computed tomography and magnetic resonance imaging. Therapy with low molecular weight heparin achieves recanalization in more than half of acute cases.

  15. An Association between Bevacizumab and Recurrent Posterior Reversible Encephalopathy Syndrome in a Patient Presenting with Deep Vein Thrombosis: A Case Report and Review of the Literature

    2012-01-01

    Full Text Available Background. The posterior reversible encephalopathy syndrome (PRES is a syndrome characterized by hypertension, headache, seizures, and visual disturbances. Causes of PRES include preeclampsia/eclampsia, hypertension, and recently bevacizumab, a monoclonal antibody vascular endothelial growth factor (VEGF inhibitor. There is no information to date about PRES recurrence in patients taking bevacizumab or descriptions of deep vein thrombosis (DVT in the setting of PRES. We reviewed data on a patient receiving bevacizumab who presented with a DVT and PRES and later developed recurrent PRES. Case. A 72-year-old man with metastatic pulmonary adenocarcinoma received maintenance bevacizumab following six cycles of carboplatin and paclitaxel. Following his eighth dose of bevacizumab, he developed a DVT as well as PRES. He made a rapid recovery and was discharged from the hospital but went on to develop PRES recurrence nine days following his original episode. Conclusion. Several mechanisms exist whereby exposure to bevacizumab could be related to the development of both DVT and PRES by inducing global endothelial dysfunction. Recurrent PRES may result from bevacizumab’s prolonged half-life (11–50 days and suboptimal blood pressure control. In the setting of bevacizumab, PRES surveillance may play a similar role in preeclampsia screening as both diseases share similar antiangiogenic signaling pathways.

    2016-04-01

    Full Text Available We present quite a rare case of extracardiac unruptured right sinus of valsalva aneurysm (SVA complicated with atherothrombosis in a young adult man. A 35-year-old male with a giant unruptured SVA arising from the right coronary sinus (RCS with extracardiac protrusion was diagnosed by echocardiography. Contrast-enhanced computed tomography (CT revealed a huge calcified aneurysm with mural thrombi originating from the aortic root, and about 80% stenosis at the initial segment of the right coronary artery (RCA. Intraoperative exploration demonstrated a giant unruptured aneurysm arising from the RCS. Different from other SVAs reported before, this aneurismal wall appeared thick and atheromatous-like. In this aneurysm, there was a small localized intima tearing and mural thrombosis, and the orifice of the RCA was almost blocked. This patient underwent surgical patch repair to prevent aneurysm rupture and coronary artery bypass grafting for RCA revascularization. In conclusion, the pathological examination demonstrated marked foam cells, inflammatory cells, and thrombosis in the aneurismal wall. Learning points: • Echocardiographic characteristics of sinus of valsalva aneurysm (SVA. • Diagnostic evaluation of extracardiac unruptured SVA. • Pathology of rare SVA.

    A 25-year-old man presented with symptoms of syncope, cough, headache and hemoptysis. Cranial MR and venography showed thrombus formation in the right transverse sinus and superior sagittal sinus. Computed tomographic pulmonary angiography (CTPA) showed an embolic thrombus in the right pulmonary truncus and lung abscess. The patient was young, and there were no signs of lower extremity deep venous thrombosis or other major risk factors for pulmonary embolism (PE) including cardiac anomaly. The only risk factor we were able to identify was the presence of the prothrombin G20210A gene mutation. Anticoagulant treatment with oral warfarin (10 mg daily) and imipenem (4X500 mg) was started. The patient was hospitalized for antibiotic and anticoagulation therapies for three weeks and was discharged on lifelong treatment with warfarin (5 mg daily).

    Portal vein thrombosis is an important cause of portal hypertension. PVT occurs in association with cirrhosis or as a result of malignant invasion by hepatocellular carcinoma or even in the absence of associated liver disease. With the current research into its genesis, majority now have an underlying prothrombotic state detectable. Endothelial activation and stagnant portal blood flow also contribute to formation of the thrombus. Acute non-cirrhotic PVT, chronic PVT (EHPVO), and portal vein thrombosis in cirrhosis are the three main variants of portal vein thrombosis with varying etiological factors and variability in presentation and management. Procoagulant state should be actively investigated. Anticoagulation is the mainstay of therapy for acute non-cirrhotic PVT, with supporting evidence for its use in cirrhotic population as well. Chronic PVT (EHPVO) on the other hand requires the management of portal hypertension as such and with role for anticoagulation in the setting of underlying prothrombotic state, however data is awaited in those with no underlying prothrombotic states. TIPS and liver transplant may be feasible even in the setting of PVT however proper selection of candidates and type of surgery is warranted. Thrombolysis and thrombectomy have some role. TARE is a new modality for management of HCC with portal vein invasion.

    The sinusitis is an inflammation of one or more breasts peri-nasals. It is common in the months of winter and it can last months or years if it is not treat. At the moment we have several means that try to offer our patients a better treatment. One of these instruments is the low power laser that for their properties to the interaction with the biological tissues offers therapeutic effects on the alive tissues, achieving at the level cellular important changes for a quick answer of the damaged tissue. We intended to demonstrate the effectiveness of the treatment with low power laser in patient with sinusitis. It was carried out an explanatory and retrospective study, where it was applied as treatment the low power laser, for that which a team of model Cuban production Fisser 21. The feminine sex, the affected age group prevailed it was among 36 to 50 years for both groups, the maxillary sinusitis prevailed regarding the frontal. The migraine, the nasal obstruction and the sensation of congestion of the head were present in most of the cases. 75% of the patients' treaties noticed improvement of the symptoms between the 1st and 3rd sessions. At the end 80% cured without necessity of a second treatment cycle. The accompanying symptoms almost disappeared in their entirety. We recommend using the treatment of low power laser, as therapy of first line for the treatment of sinusitis of infectious cause. (Author)

    2006-01-01

    Objective: to determine the frequency and localization of parenchymal abnormalities in cerebral venous thrombosis on magnetic resonance imaging and magnetic resonance angiography as well as their correlation with the territory and affected venous drainage. Materials and methods: retrospective analysis (1996 to 2004) of 21 patients (3 male and 18 female) age range between 3 and 82 years (mean 40 years, median 36 years) with clinical and radiological diagnosis of cerebral venous thrombosis on magnetic resonance imaging and magnetic resonance angiography in 2D PC, 3D PC and contrast-enhanced 3D TOF sequences. The statistical analysis was performed with the qui-square test. Four patients had follow-up exams and three patients underwent digital subtraction angiography. Results: main predisposing factors were: infection, use of oral contraceptives, hormone replacement therapy and collagenosis. Predominant symptoms included: focal deficit, headache, alteration of consciousness level and seizures. Most frequent parenchymal manifestations were: cortical/subcortical edema or infarct, venous congestion and collateral circulation, meningeal enhancement and thalamic and basal ganglia edema or infarct. Occlusion occurred mainly in superior sagittal, left transverse, left sigmoid and straight sinuses. Cavernous sinus and cortical veins thrombosis are uncommon events. Conclusion: cerebral venous thrombosis is an uncommon cause of stroke, with favorable prognosis because of its reversibility. Diagnosis is highly dependent on the radiologist capacity to recognize the presentations of this disease, principally in cases where the diagnosis is suggested by parenchymal abnormalities rather than necessarily by visualization of the thrombus itself. An accurate and rapid diagnosis allows an immediate treatment, reducing the morbidity and mortality rates. (author)

    Full Text Available A 45-year-old male patient presented with gradual onset of headache, vomiting and blurring of vision of 28 days duration. Ophthalmological examination revealed normal anterior segment and pupillary reflex. No abnormality was detected in the vitreous. Optic disc showed features of advanced papilledema with normal macula and retinal periphery in both eyes. Visual acuity was 20/200 in the right eye and counting fingers close range in the left eye. Non-contrast computed tomography of brain was normal and magnetic resonance imaging showed sagittal sinus thrombosis without any evidence of venous infarction or intracranial mass. Routine hematological investigations revealed increased hemoglobin level, packed cell volume and leucocytosis. Further investigation revealed increased Vitamin B12 and decreased serum erythropoietin. A diagnosis of polycythemia vera was made from the above findings. This case is being presented for the rarity of association of polycythemia vera with bilateral advanced papilledema due to sagittal sinus thrombosis.

    Cerebral venous thrombosis is a rare entity with widely variable clinical signs: thus, a high degree of suspicion is required for diagnosis. It affects the dural sinuses and may or may not invade cerebral veins. The diagnosis has usually been based on an angiographic study although, at the present time, new noninvasive imaging techniques, such as computed tomography, magnetic resonance and magnetic resonance angiography are being employed in a growing number of cases. Treatment should involve symptomatic and etiologic therapy. Although anti coagulation would appear to be a reasonable option in these patients, it remains controversial. As in other processes such as pulmonary embolism and coronary thrombosis, the introduction of novel and increasingly safe fibrinolytic drugs, together with technical innovations in the field of interventional neuroradiology, is changing the perspectives for the management of these patients. We present the case of a 43-year-old woman with right sinus thrombosis who was treated with local thrombolysis plus alteplase (tissue plasminogen activator). The authors describe the technique employed and review the literature. (Author) 16 refs.

    Gangliocytic lesions of the pituitary gland producing Cushing's disease are extremely rare entities that may exist with or without a pituitary adenoma. The latter have been designated mixed pituitary adenoma-gangliocytomas, the majority of which produce growth hormone, not adrenocorticotropin (ACTH), and are localized to the anterior gland. We now report an immunocompetent woman with hypercortisolism who presented with an intranasal aspergilloma eroding the bony sellar floor. The fungal ball was contiguous with, and extended into, a large neurohypophyseal-centered mass. Transsphenoidal resection revealed a gangliocytic lesion of the posterior gland with small clusters of intimately admixed ACTH-immunoreactive adenoma cells as the cause of her Cushing's disease. Rare transitional sizes and shapes of cells coupled with immunohistochemical findings supported interpretation as advanced neuronal metaplasia within an ACTH adenoma. This mixed ACTH adenoma-gangliocytoma is the first example to present clinically with an opportunistic infection.

    Essentials The clinical value of IgM antibodies in thrombotic antiphospholipid syndrome (APS) is debated. By review of literature, we reconsidered the clinical value of IgM antibodies in thrombotic APS. More significant correlations with thrombosis were found for the IgG compared to IgM isotype. Unavailability of paired IgG/IgM results hampers evaluating the added value of IgM positivity. Click to hear Dr de Groot's perspective on antiphospholipid syndrome Background Despite the update of the classification criteria for the antiphospholipid syndrome (APS), difficulties persist in the identification of patients at risk for thrombosis. Current guidelines include assays detecting IgG/IgM anti-β2 -glycoprotein I and anti-cardiolipin antibodies, although the relevance of IgM antibodies has been debated. Objectives Through a review of the literature from 2001 to 2014, we aimed to formally establish the thrombotic risk stratification potential of IgM as compared with IgG anti-phospholipid antibodies (aPLs). Patients/methods One thousand two hundred and twenty-eight articles were selected by a computer-assisted search of the literature. Of the 177 studies that met our inclusion criteria, the clinical value of IgG/IgM aPLs was established through analysis of odds ratios for thrombosis or percentage of positives in the thrombotic population. Results/conclusions We clearly found more significant correlations with thrombosis for the IgG than for the IgM isotype. Nonetheless, in a minority of studies, significant associations with thrombosis were found for IgM but not IgG antibodies. The unavailability of paired results of IgG and IgM for each separate patient hampers evaluation of the added value of isolated IgM positivity. To fully take advantage of results obtained by future studies, we strongly encourage scientists to provide all studied information per patient. We planned a large multicenter study to investigate clinical associations of isolated/combined positivity for

    Purpose: The purpose of this study was to investigate the feasibility of clot visualization in small sinus and cortical veins with contrast enhanced MRA in a cerebral venous thrombosis animal model using a blood pool contrast agent, Gadofosveset, and high spatial resolution imaging. Material and methods: For induction of cerebral venous thrombosis a recently developed combined interventional and microsurgical model was used. Cerebral sinus and cortical vein thrombosis was induced in six pigs. Two further pigs died during the procedure. Standard structural, time-of-flight- and phase contrast-angiograms were followed by fast time resolved high resolution 3D MRA (4D MRA) and subsequent high spatial resolution 3D MRA in the equilibrium phase with and without addition of parallel imaging. Visualization of the clots using the different sequences was subjectively compared and contrast-to-noise ratio (CNR) was assessed. Results: In the remaining six animals the procedure and MR-imaging protocol including administration of Gadofosveset was successfully completed. The 3D high resolution MRA in the equilibrium phase without the addition of parallel imaging was superior to all the other applied MR measurement techniques in terms of visualization of the clots. Only applying this sequence bridging vein thromboses were also seen as a small filling defect with a high CNR of >18. Conclusion: Only the non-accelerated high spatial resolution 3D MRA in the equilibrium in conjunction with the blood pool agent Gadofosveset allows for high-contrast visualization of very small clots in the cerebral sinus and cortical veins. Statement clinical impact: Detection of cortical vein thrombosis is of high clinical impact. Conventional MRI sequences often fail to visualize the clot. We could demonstrate that, in contrast to conventional sequences, with high spatial resolution 3D MRA in the equilibrium in conjunction with the blood pool agent Gadofosveset very small clots in the cerebral sinus and

    The aim of this review is to discuss current diagnostic approaches to, and classification of, patients presenting with thrombocytosis, in light of novel information derived from the discovery of specific molecular abnormalities in chronic myeloproliferative disorders (CMPD), which represent the most common cause of primary thrombocytosis. The JAK2V617F and the MPLW515L/K mutations have been found in patients with essential thrombocythemia, polycythemia vera, and primary myelofibrosis, and less frequently in other myeloproliferative disorders complicated by thrombocytosis. However, neither mutation is disease specific nor is it universally present in patients with elevated platelet counts due to a CMPD; therefore, distinguishing between reactive and primary forms of thrombocytosis, as well as among the different clinical entities that constitute the CMPD, still requires a multifaceted diagnostic approach that includes as a key step the accurate evaluation of bone marrow histology. The role of elevated platelet counts in thrombosis, which represent the predominant complication of CMPD,significantly affecting prognosis and quality of life as well as, paradoxically, in the pathogenesis of the hemorrhagic manifestations, will be discussed. Established and novel potential risk factors for thrombosis, including the clinical relevance of the JAK2V617F mutation, and current management strategies for thrombocytosis are also briefly discussed.

    There are asymmetries in the sizes of transverse sinus and intraocular pressure. The purpose of this study was to investigate possible relationships between the asymmetry of transverse sinuses in TOF MR venography and intraocular pressures of right and left eyes. In this study, subjects were 63 male and 42 female medical school students, aged 18-21 years (mean±SD; 19.72±0.67 years). Subjects with neurological and ophthalmologic disease, particularly dural sinus thrombosis, myopia, trauma and glaucoma, were excluded the study. Subjects were divided into five groups according to the magnitudes of the right- and left-transverse sinuses in MR venography results. There is a functional relation between intraocular pressures of the right and left eyes and asymmetry of the transverse sinus. If the transverse sinus on one side is larger and its venous drainage is greater, the intraocular pressure of the eye on this side is lower. It can be speculated that the transverse sinus size may be associated with pathogenesis of diseases with increased intraocular pressure such as glaucoma. We aim to determine the relation between the size and drainage of transverse sinuses in TOF MR venography and intraocular pressure in patients with open-angle glaucoma in our next study. (orig.)

    Unenhanced brain computed tomography (CT) is inexpensive, easily available, and the first-choice imaging modality for patients presenting with various neurologic symptoms. Venous thrombosis is not rare in childhood, but diagnosis can be difficult. In some cases, only denser vessels can be used to highlight an issue. The aim of this study was to retrospectively evaluate the relationship between X-ray attenuation and hemoconcentration in a pediatric population. This study enrolled 99 pediatric patients who had been referred radiology department for unenhanced brain CT. Images were retrospectively evaluated for measurement of dural sinus densities from four distinct dural sinus locations. Correlation between mean Hounsfield unit (HU) values and hemoglobin/hematocrit (Hb/Htc) levels, as well as age and gender were further analyzed. There was a strong correlation between mean HU and Hb levels (r = 0.411; standard deviation: 0.001) and also between mean HU and Htc levels (r = 0.393; p pediatric group. In conclusion, before deciding between a diagnosis of thrombosis and a determination of normal findings during an evaluation of unenhanced CT in a pediatric population, radiologists should consider complete blood count results as well as H:H ratios.

  13. Idiopathic Bilateral External Jugular Vein Thrombosis.

    Hindi, Zakaria; Fadhel, Ehab

    2015-08-20

    Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow's triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely. Bilateral idiopathic external jugular veins thrombosis is extremely rare and can be an indicator of early malignancy or hidden infection. While previous reports in the literature have associated jugular vein thrombosis with malignancy, the present case shows that external jugular vein thrombosis can also be found in persons without malignancy.

    Full Text Available Carotid sinus hypersensitivity is a common cause of fainting and falls in the elderly, and can be diagnosed by carotid sinus massage. We present a 67-year-old diabetic man who was admitted with hyperglycemia. During thyroid examination, clouding of consciousness occurred with unilateral palpation. Asystole was documented for 4.8 seconds and suspected for 7 seconds upon carotid sinus massage. A cardioverter defibrillator was implanted. Carotid sinus hypersensitivity should be kept in mind when examining diabetic patients.

    An increased risk of venous thromboembolism has been demonstrated following renal transplantation. Commonly reported sites have been deep vein thrombosis, pulmonary thromboembolism and vascular thrombosis involving the graft. Cerebral venous thrombosis (CVT) has not been reported in literature so far. A 36-year-old male patient, transplanted in January 2005 with normal graft functions, was admitted with history of headache, blurring of vision and vomiting. Examination revealed papilledema and no neurological deficits. Baseline investigations and analysis of cerebrospinal liquid were normal. Cerebral magnetic resonance venogram revealed extensive CVT involving superior sagittal sinus, bilateral transverse sinuses and the right sigmoid sinus. He was investigated for a thrombophilic disorder; serum homocysteine, protein C and S levels, antiphospholipid antibody and antithrombin-III levels were done despite which no conclusive diagnosis could be arrived at. To our knowledge, this is the first report of extensive CVT described in a transplant recipient. Ne definite prothrombotic or predisposing factors could be identified in our patient and the cause of CVT remains unclear. (author)

    2011-07-01

    Full Text Available Behçet syndrome (BS is a multisystem vasculitis with unknown etiology and a unique geographic distribution. The disease course is characterized by exacerbations and remissions while abating as the years pass. The usual onset is in the third decade. Recurrent skin mucosa lesions and sight threatening panuveitis are the hallmark of the disease. Males are more severely affected than females. Vascular involvement can occur in up to 40 % of cases.  BS is unique among the vasculitides in that it may involve all sizes and types of vessels. It affects the veins more than the arteries. Lower extremity vein thrombosis is the most frequent manifestation of vascular involvement, followed by vena cava thrombosis, pulmonary artery aneurysms, Budd-Chiari syndrome, peripheral artery aneurysms, dural sinus thrombosis and abdominal aorta aneurysms. Vascular involvement is frequently associated with constitutional symptoms and increased acute phase response and is the major cause of increased mortality.  A predominantly neutrophilic vasculitis around the vaso vasorum is typical of BS. The thrombus is tightly adherent to the vessel wall which probably explains why thromboembolism is so rare despite the high frequency of venous disease. Thrombophilic factors do not seem to explain thrombotic tendency in BS. Immunosuppressive treatment is essential in suppression and preventing the attacks.

    The thrombosis of the inferior vena cava account for around the 15% of the cases of deep venous thrombosis. This is the case of a puerperal primigravida with a cesarean section labor presenting with a thrombosis initially in the right ovarian vein and then extension to the inferior vena cava. Treatment included low molecular weight heparin in anticoagulant doses; rest with elevation of the extremities and elastic bandage. After a satisfactory process evolution with partial lysis of the thrombus, the oral anticoagulation with Acenocumarol for 6 months was started. The second patient, a man aged 73 with backgrounds of an operated hepatic hydatidosis, had a thrombosis of the infrarenal inferior vena cava and agenesia of retrohepatic segment of the inferior vena cava. The patient remains with anticoagulant treatment including Acenocumarol, elastic bandage and hygienic care. As sequela he had a postphlebitic syndrome and reworsening of the edema leading to its admission in two occasions.(author)

    To determine the prevalence,location, and distribution of sinus tracts in patients referred for endodontic consultation. This cohort study included 1,119 subjects referred for endodontic consultation, 108 of whom presented with sinus tracts. Following clinical and radiographic examination, the diameter of the rarifying osteitis lesion on the radiograph was measured and the path and origin of the sinus tracts determined. Signs and symptoms, tooth site,buccal/lingual location, and diameter were recorded. Data were statistically analyzed using Pearson chi-square test. Sinus tracts originated mainly from maxillary teeth (63.1%); only 38.9% originated from mandibular teeth. Chronic periapical abscess was the most prevalent diagnosed origin (71.0%). Broken restorations were highly associated with the presence of sinus tracts (53.0%). The most frequent site of orifices was buccal(82.4%), followed by lingual or palatal (12.0%). Orifices on the lingual aspect of the gingiva were observed in mandibularmolars. There was an 86.8% correlation between the occurrence of an apically located sinus tract and apical rarifying osteitis(P<.01). Sinus tract in the lingual or palatal aspect of the gingiva is relatively common. Practitioners should look for signs of sinus tract during routine examination

    The renal sinus extends from the perinephric space into the deep recess situatede on the tuated on the medial border of the kidney. Contained within the space are the pelvocalyceal system, fat and lymph nodes. Arteries, veins, lymphatic channels and nerves of the autonomic nervous system traverse the sinus, and various pathological conditions may occur in this area. These various sinusal lesions may present a similar imaging appearance, and diagnostic errors may frequently occur, especially if diagnosis is attempted without first clearly understanding the several possibilities. This pictorial essay demonstrates various renal sinus lesions and emphasizes the proper combination of multimodal imaging. For evaluation of the extent of the lesious, CT is the preferred imaging modality, since this best depicts the anatomy of the renal sinus.

    Under analysis are etiology, clinical picture and diagnosis of a septic thrombosis of cavernous sinuses in 28 patients. The authors have shown the interrelationship between local manifestations of the disease, injuries of the brain and its sheaths and septic complications (abscessing pneumonia as the most severe of them). A scheme of the complex treatment of patients with thrombosis of the cavernous sinus is proposed. The leading role in this treatment is played by intracarotid infusion of antibiotics in combination with anticoagulant drugs, vasodilatatory agents and novocaine as well as the therapy of septic complications (abscesses of the face and hairy part of the head, meningoencephalitis, pneumonia).

    Background: despite the proven effectiveness of preventive therapy for deep vein thrombosis, a significant proportion of patients at risk for thromboembolism do not receive prophylaxis during hospitalization. Our objective was to determine the adherence to thrombosis prophylaxis guidelines in a general hospital as a quality control strategy. Methods: a random audit of clinical charts was conducted at the Tijuana General Hospital, Baja California, Mexico, to determine the degree of adherence to deep vein thrombosis prophylaxis guidelines. The instrument used was the Caprini's checklist for thrombosis risk assessment in adult patients. Results: the sample included 300 patient charts; 182 (60.7 %) were surgical patients and 118 were medical patients. Forty six patients (15.3 %) received deep vein thrombosis pharmacologic prophylaxis; 27.1 % of medical patients received deep vein thrombosis prophylaxis versus 8.3 % of surgical patients (p < 0.0001). Conclusions: our results show that adherence to DVT prophylaxis at our hospital is extremely low. Only 15.3 % of our patients at risk received treatment, and even patients with very high risk received treatment in less than 25 % of the cases. We have implemented strategies to increase compliance with clinical guidelines.

    Although diseases of the paranasal sinuses have a relatively homogeneous clinical presentation, their causes can vary considerably. Radiological imaging only became relevant in paranasal sinus diagnostics following the introduction of cross-sectional imaging. In addition to technical details on imaging procedures and the individual criteria of the different modalities, anatomic details and congenital variations are presented. Particularly in acute inflammatory diseases as well as traumatic lesions, imaging is essential in preoperative planning and postoperative control. The article gives a detailed description of options in radiologic imaging of the paranasal sinuses. (orig.) [de

    We report an unusual case of a displaced maxillary molar and associated dentigerous cyst within the maxillary sinus in an adolescent presenting as recurrent sinusitis. Although a rare cause of sinusitis in children, dentigerous cysts should be included in the differential diagnosis for causes of persistent or recurrent sinusitis in this age group. This report provides further evidence for obtaining imaging studies when managing pediatric sinusitis that does not respond to standard antibiotic therapy. We discuss management options for these lesions including the differential diagnoses and need for follow-up. (orig.)

    Objective: to determine the frequency and localization of parenchymal abnormalities in cerebral venous thrombosis on magnetic resonance imaging and magnetic resonance angiography as well as their correlation with the territory and affected venous drainage. Materials and methods: retrospective analysis (1996 to 2004) of 21 patients (3 male and 18 female) age range between 3 and 82 years (mean 40 years, median 36 years) with clinical and radiological diagnosis of cerebral venous thrombosis on magnetic resonance imaging and magnetic resonance angiography in 2D PC, 3D PC and contrast-enhanced 3D TOF sequences. The statistical analysis was performed with the qui-square test. Four patients had follow-up exams and three patients underwent digital subtraction angiography. Results: main predisposing factors were: infection, use of oral contraceptives, hormone replacement therapy and collagenosis. Predominant symptoms included: focal deficit, headache, alteration of consciousness level and seizures. Most frequent parenchymal manifestations were: cortical/subcortical edema or infarct, venous congestion and collateral circulation, meningeal enhancement and thalamic and basal ganglia edema or infarct. Occlusion occurred mainly in superior sagittal, left transverse, left sigmoid and straight sinuses. Cavernous sinus and cortical veins thrombosis are uncommon events. Conclusion: cerebral venous thrombosis is an uncommon cause of stroke, with favorable prognosis because of its reversibility. Diagnosis is highly dependent on the radiologist capacity to recognize the presentations of this disease, principally in cases where the diagnosis is suggested by parenchymal abnormalities rather than necessarily by visualization of the thrombus itself. An accurate and rapid diagnosis allows an immediate treatment, reducing the morbidity and mortality rates. (author)

    2010-01-01

    Full Text Available Purpose. Collet-Sicard syndrome is a very rare condition characterised by unilateral palsy of the IX–XII cranial nerves. It is distinguished from Villaret syndrome by lack of presence of sympathetic involvement. Current literature contains only two cases of Collet-Sicard syndrome due to idiopathic internal jugular vein thrombosis. Method and Results. We report the case of Collet-Sicard syndrome in a 30-year-old man who presented with delayed development of XIth nerve dysfunction, due to internal jugular vein-sigmoid sinus thrombosis. A multidisciplinary team approach was employed in the management of this patient. At three-month followup, he had significantly improved swallowing, and repeat computed tomography neck scan showed partial recanalisation of the right internal jugular vein. Conclusion. In suspected Collet-Sicard syndrome, a focal primary lesion or metastasis to the temporal bone must be excluded, and sigmoid-jugular complex thrombosis should be considered in the differential diagnosis. Early recognition and treatment may result in significant functional recovery.

    1982-01-01

    Seventy patients with rheumatic mitral disease were studied by M-Mode and 2D echocardiography in order to detect left atrial thrombosis before surgery. Thrombosis were suspected by the observation of abnormal echoes in the left atrium. During surgery 17 (24%) patients had atrial thrombosis. It had been suspected by echocardiography in 12 (sensitivity 70%). In 53 patients thrombosis were not found during surgery; in 46 the echo had been also negative (specificity 86%). There was a false positive detection of thrombosis by echo in 7 patients (14%) and false negativity in 5 (30%). Patients with atrial thrombosis had atrial fibrilation in 91% of cases; and the most frequent valvular disease was mitral stenosis. There was not a direct relationship among existence of left atrial thrombosis and the anteroposterior diameter of the left atrium as measured by echo. We conclude that echocardiography has good specificity to rule out atrial thrombosis and moderate sensitivity to detect it in rheumatic mitral disease.

    A 59 year-old male patient with a history of hypertension and regular consumption of sildenafil entered the service because of acute stroke and headache seizure. Physical examination detected left hemiplegia. By skull nuclear gadolinium magnetic resonance, an expansive lesion is observed which caught heterogeneously contrast. Possible diagnosis of high-grade brain glioma was raised. Right frontoparietal craniotomy was performed and a tumor lesion was not visualized. After ruling out the presence of high-grade glioma, the diagnosis of hemorrhagic venous infarction was assessed. CT angiography and clotting was made to rule out prothrombotic states to justify this disease entity. Special hematology studies were within normal values. The case was concluded as a venous sinus thrombosis associated with the use of sildenafil. (author)

    Orbital varices are venous malformations produced by an abnormal dilatation of one or more orbital veins, probably associated with congenital weakness of the vascular wall. They are rare lesions, usually occurring in young patients, that produce intermittent proptosis related to the increase in the systemic venous pressure. The presence of hemorrhage or thrombosis is associated with rapid development of proptosis, pain and decreased ocular motility. We report the cases of two adult patients with orbital varices complicated by thrombosis in whom the diagnosis was based on computed tomography. The ultrasound and magnetic resonance findings are also discussed. (Author) 16 refs

    Bilateral simultaneous sampling of the inferior petrosal sinuses is an extremely sensitive, specific, and accurate test for diagnosing Cushing disease and distinguishing between that entity and the ectopic ACTH syndrome. It is also valuable for lateralizing small hormone-producing adenomas within the pituitary gland. The inferior petrosal sinuses connect the cavernous sinuses with the ipsilateral internal jugular veins. The anatomy of the anastomoses between the inferior petrosal sinus, the internal jugular vein, and the venous plexuses at the base of the skull varies, but it is almost always possible to catheterize the inferior petrosal sinus. In addition, variations in size and anatomy are often present between the two inferior petrosal sinuses in a patient. Advance preparation is required for petrosal sinus sampling. Teamwork is a critical element, and each member of the staff should know what he or she will be doing during the procedure. The samples must be properly labeled, processed, and stored. Specific needles, guide wires, and catheters are recommended for this procedure. The procedure is performed with specific attention to the three areas of potential technical difficulty: catheterization of the common femoral veins, crossing the valve at the base of the left internal jugular vein, and selective catheterization of the inferior petrosal sinuses. There are specific methods for dealing with each of these areas. The sine qua non of correct catheter position in the inferior petrosal sinus is demonstration of reflux of contrast material into the ipsilateral cavernous sinus. Images must always be obtained to document correct catheter position. Special attention must be paid to two points to prevent potential complications: The patient must be given an adequate dose of heparin, and injection of contrast material into the inferior petrosal sinuses and surrounding veins must be done gently and carefully. When the procedure is performed as outlined, both inferior

    Mechanical measures such as graduated compression stockings and intermittent compression boots are available for venous thrombosis prophylaxis, but compliance may be limited. Plantar venous pneumatic compression devices have attained widespread acceptance by both patients and nurses because of their comfort and compact size, but their track record for efficacy is poor. Inferior vena cava filters prevent pulmonary embolism, but do not halt the thrombotic process or prevent venous thrombosis. Pharmacologic prophylaxis traditionally has relied upon minidose unfractionated heparin; however, re-examination is warranted in the face of increasingly ill and complex patients. My opinion is that small, fixed doses of once-daily low molecular weight heparin will eventually replace minidose unfractionated heparin as the standard pharmacologic prophylaxis regimen for most surgical and medical patients. Prolongation of prophylaxis after hospital discharge should receive increased emphasis. Most patients being transferred to a skilled nursing facility should receive venous thromboembolism prophylaxis. Similarly, most patients undergoing total hip or knee replacement should receive prolonged preventive regimens, with at least 1 month of anticoagulation. Despite advances, certain aspects of venous thrombosis prophylaxis remain problematic. First, a surprisingly high number of hospitalized patients develop venous thrombosis because of failed (rather than omitted) prophylaxis. Second, many patients in intensive care have a combination of peripheral vascular disease and active bleeding (usually gastrointestinal) that precludes mechanical or pharmacologic prophylaxis. Third, neurosurgical patients undergoing craniotomy for brain tumors suffer a high rate of venous thrombosis and major pulmonary embolism despite the routine use of combined mechanical and pharmacologic prophylaxis. My opinion is that these three areas, in addition to the hospital culture of prophylaxis, should receive

    Full Text Available Cerebral sinovenous thrombosis (CSVT is a rare but serious cerebrovascular disorder affecting children from the newborn period through childhood and adolescence. The incidence is estimated at 0.6/100,000/year, with 30–50% occurring in newborns. Causes are diverse and are highly age dependent. Acute systemic illness is the dominant risk factor among newborns. In childhood CSVT, acute infections of the head and neck such as mastoiditis are most common, followed by chronic underlying diseases such as nephrotic syndrome, cancer, and inflammatory bowel disease. Signs and symptoms are also age related. Seizures and altered mental status are the commonest manifestations in newborns. Headache, vomiting, and lethargy, sometimes with 6th nerve palsy, are the most common symptoms in children and adolescents. Recent multicenter cohort studies from North America and Europe have provided updated information on risk factors, clinical presentations, treatment practices, and outcomes. While systemic anticoagulation is the most common specific treatment used, there are wide variations and many uncertainties even among experts concerning best practice. The treatment dilemma is especially pronounced for neonatal CSVT. This is due in part to the higher prevalence of intracranial hemorrhage among newborns on the one hand, and the clear evidence that newborns suffer greater long-term neurologic morbidity on the other hand. With the advent of widespread availability and acceptance of acute endovascular therapy for arterial ischemic stroke, there is renewed interest in this therapy for children with CSVT. Limited published evidence exists regarding the benefits and risks of these invasive therapies. Therefore, the authors of current guidelines advise reserving this therapy for children with progressive and severe disease who have failed optimal medical management. As research focused on childhood cerebrovascular disease continues to grow rapidly, the future prospects

    Full Text Available This paper is about a posttraumatic distal ulnar artery thrombosis case that has occurred after a single blunt trauma. The ulnar artery thrombosis because of chronic trauma is a frequent condition (hypothenar hammer syndrome but an ulnar artery thrombosis because of a single direct blunt trauma is rare. Our patient who has been affected by a single blunt trauma to his hand and developed ulnar artery thrombosis has been treated by resection of the thrombosed ulnar artery segment. This report shows that a single blunt trauma can cause distal ulnar artery thrombosis in the hand and it can be treated merely by thrombosed segment resection in suitable cases.

    The demonstration of an underlying prothrombotic condition in cerebral venous thrombosis (CVT) may have important practical consequences in terms of prevention. Thyrotoxicosis through a hypercoagulable state may be a predisposing factor for CVT. The authors present the cases of 4 patients who developed CVT and hyperthyroidism. At the acute stage, hyperthyroidism was associated with an increase in factor VIII (FVIII). At follow-up, FVIII level remained increased in 2 patients. Hyperthyroidism may have an impact on FVIII level. Accordingly in patients with hyperthyroidism and neurological symptoms, the diagnosis of CVT should be considered and an exhaustive coagulation screening may be appropriate. (c) 2005 S.

    Full Text Available

    Behçet syndrome (BS is a multisystem vasculitis with unknown etiology and a unique geographic distribution. The disease course is characterized by exacerbations and remissions while abating as the years pass. The usual onset is in the third decade. Recurrent skin mucosa lesions and sight threatening panuveitis are the hallmark of the disease. Males are more severely affected than females. Vascular involvement can occur in up to 40 % of cases.  BS is unique among the vasculitides in that it may involve all sizes and types of vessels. It affects the veins more than the arteries. Lower extremity vein thrombosis is the most frequent manifestation of vascular involvement, followed by vena cava thrombosis, pulmonary artery aneurysms, Budd-Chiari syndrome, peripheral artery aneurysms, dural sinus thrombosis and abdominal aorta aneurysms. Vascular involvement is frequently associated with constitutional symptoms and increased acute phase response and is the major cause of increased mortality.  A predominantly neutrophilic vasculitis around the vaso vasorum is typical of BS. The thrombus is tightly adherent to the vessel wall which probably explains why thromboembolism is so rare despite the high frequency of venous disease. Thrombophilic factors do not seem to explain thrombotic tendency in BS. Immunosuppressive treatment is essential in suppression and preventing the attacks.

    Despite the progress achieved in the design of mechanical prosthetic valves, prosthetic valve thrombosis remains a frequent cause of morbidity, usually due to incorrect anticoagulation. A patient was presented with mitral prosthetic thrombosis one year after implantation, who had been diagnosed by transthoracic transesophageal echocardiography imaging and 64-slice computed tomography. Thrombolytic therapy was successful and led to the satisfactory evolution of the patient

    Venous thrombosis affecting cerebral veins and sinuses (CVT) is an uncommon neurological condition. Traditionally patients are treated with intravenous heparin followed by an oral vitamin K antagonist like warfarin. Direct oral anticoagulants (DOACs) may offer advantages over warfarin. There is evidence to demonstrate the effectiveness of both dabigatran and rivaroxaban. No data, however, has been published describing the use of apixaban in patients with CVT. Report of three cases of CVT and review literature on available treatment options; efficacy and safety of novel oral anticoagulants in patients with systemic thrombosis. All patients presented with typical features of CVT. After confirming the diagnosis, they were acutely treated with heparin and later discharged on apixaban. During follow up visits, they tolerated apixaban well and did not have any bleeding complications. Follow up scans showed resolution of the thrombus and recanalization. CVT is an uncommon neurological condition and is often complicated by associated intraparenchymal hemorrhage. Although not recommended in current guidelines, apixaban may be a safe and effective option for the treatment of CVT. Copyright © 2017 Elsevier B.V. All rights reserved.

  1. Terminal Posterior Tilted Implants Planned as a Sinus Graft Alternative for Fixed Full-Arch Implant-Supported Maxillary Restoration: A Case Series with 10- to 19-Year Results on 44 Consecutive Patients Presenting for Routine Maintenance.

    Posterior maxillary tilted implants are gaining prevalence as an alternative to sinus grafts supporting fixed maxillary restorations. This paper reports long-term results after loading using this technique. Consecutive patients presenting for either routine hygiene maintenance or unplanned emergency care who had received tilted implants as a sinus graft alternative to support fixed fully implant-supported restoration of an edentulous maxilla and were followed for a minimum of 10 years from initial implant placement were included in this evaluation. Forty-four patients were identified: 40 with bilateral tilted implants and 4 with one tilted and one axial posterior implant. Eight patients received one-piece fixed porcelain-to-gold screw-retained restorations, and thirty-six patients received a fully implant-supported patient-removable Marius Bridge. Seventy-nine out of 84 originally loaded posterior tilted implants survived a minimum of 10 years loading; one tilted implant was lost at 10 years. Eight additional posterior implants were placed for either these lost tilted posterior implants or as proactive supplemental support; one of these replacement tilted implants survived for at least 10 years and is included in the data. All patients have maintained continuous fixed function throughout the follow-up period. Forty-one out of 44 patients continue with the original restoration, 33 without modification or removal of the fixed restoration or implant-connecting bar. One porcelain-to-gold and seven Marius Bridges had framework modifications to accommodate additional implants; 3 Marius Bridge restorations were replaced with a newer generation. Within the limits of this retrospective study, the results show that continuous fixed function of fully implant-supported maxillary restorations using posterior tilted implants in terminal positions of support as a sinus graft alternative combined with axial anterior implants is possible over a prolonged period. Loss of a posterior

  2. Ambient air pollution and thrombosis.

    2018-01-03

    Air pollution is a growing public health concern of global significance. Acute and chronic exposure is known to impair cardiovascular function, exacerbate disease and increase cardiovascular mortality. Several plausible biological mechanisms have been proposed for these associations, however, at present, the pathways are incomplete. A seminal review by the American Heart Association (2010) concluded that the thrombotic effects of particulate air pollution likely contributed to their effects on cardiovascular mortality and morbidity. The aim of the current review is to appraise the newly accumulated scientific evidence (2009-2016) on contribution of haemostasis and thrombosis towards cardiovascular disease induced by exposure to both particulate and gaseous pollutants.Seventy four publications were reviewed in-depth. The weight of evidence suggests that acute exposure to fine particulate matter (PM 2.5 ) induces a shift in the haemostatic balance towards a pro-thrombotic/pro-coagulative state. Insufficient data was available to ascertain if a similar relationship exists for gaseous pollutants, and very few studies have addressed long-term exposure to ambient air pollution. Platelet activation, oxidative stress, interplay between interleukin-6 and tissue factor, all appear to be potentially important mechanisms in pollution-mediated thrombosis, together with an emerging role for circulating microvesicles and epigenetic changes.Overall, the recent literature supports, and arguably strengthens, the contention that air pollution contributes to cardiovascular morbidity by promoting haemostasis. The volume and diversity of the evidence highlights the complexity of the pathophysiologic mechanisms by which air pollution promotes thrombosis; multiple pathways are plausible and it is most likely they act in concert. Future research should address the role gaseous pollutants play in the cardiovascular effects of air pollution mixture and direct comparison of potentially

    High platelet reactivity (HPR) was studied in patients presenting with ST-segment elevation myocardial infarction (STEMI) due to stent thrombosis (ST) undergoing immediate percutaneous coronary intervention (PCI). HPR on P2Y 12 inhibitors (HPR-ADP) is frequently observed in stable patients who have experienced ST. The HPR rates in patients presenting with ST for immediate PCI are unknown. Consecutive patients presenting with definite ST were included in a multicenter ST registry. Platelet reactivity was measured before immediate PCI with the VerifyNow P2Y 12 or Aspirin assay. Platelet reactivity was measured in 129 ST patients presenting with STEMI undergoing immediate PCI. HPR-ADP was observed in 76% of the patients, and HPR on aspirin (HPR-AA) was observed in 13% of the patients. HPR rates were similar in patients who were on maintenance P2Y 12 inhibitor or aspirin since stent placement versus those without these medications. In addition, HPR-ADP was similar in patients loaded with a P2Y 12 inhibitor shortly before immediate PCI versus those who were not. In contrast, HPR-AA trended to be lower in patients loaded with aspirin as compared with those not loaded. Approximately 3 out of 4 ST patients with STEMI undergoing immediate PCI had HPR-ADP, and 13% had HPR-AA. Whether patients were on maintenance antiplatelet therapy while developing ST or loaded with P2Y 12 inhibitors shortly before undergoing immediate PCI had no influence on the HPR rates. This raises concerns that the majority of patients with ST have suboptimal platelet inhibition undergoing immediate PCI. Copyright © 2017 American College of Cardiology Foundation.

    Bipolaris is an increasingly recognized cause of fungal sinusitis. Reports of imaging features are sparse. Our purpose was to review the imaging features in patients with Bipolaris fungal sinusitis. A review of our data showed seven patients with culture-proven Bipolaris fungal sinusitis. Computed tomography of the paranasal sinuses in all the patients and MRI in five patients were analysed for the location, nature, extent of the disease and density/ signal characteristics on CT/MRI. The sphenoid and posterior ethmoid sinuses were most often involved (six of seven), followed by the anterior ethmoid sinus (five of seven), frontal sinus (four of seven) and maxillary sinus (three of seven) involvement. Five of seven cases had bilateral disease. Secretions were seen to fill the sinus and were expansile in nature in six of seven cases. Bony erosion was noted in all the patients. Air-fluid levels and bony sclerosis were rarely seen. Computed tomography showed central hyperdensity in all the cases. In the corresponding MR images (n = 5), the sinus contents appeared hyperintense on T1-weighted images and hypointense on T2-weighted images. Extension into the nasal cavity was found in six of seven cases. Five of seven cases had intracranial (extradural) spread. Intraorbital extension was seen in three of seven cases, with associated optic nerve compression in two. All the patients responded to surgical debridement, and systemic antifungal therapy was not required. Bipolaris fungal sinusitis typically presents with an allergic fungal sinusitis picture with expansile sinus opacification and bony erosions. There is central hyperdensity on CT scan, which appears hyperintense on T1-weighted and hypointense on T2-weighted MR images

She had no risk factors and all her thrombophilia workup was normal, however, she was found to be dyslipidemic which may have contributed to atherosclerosis and predispose to thrombosis. Despite anticoagulation, her visual acuity deteriorated. This case illustrates the possibility of unpredictable visual complication of interferon. Frequent eye examination should be undertaken in patients having underlying risk factors like diabetes, hypertension or dyslipidemia undergoing interferon therapy. (author)

    This case reports the sudden development of large burden of thrombi in the left anterior descending coronary artery immediately following distal left main stenting using TAP technique in a middle aged man who presented with non ST-segment elevation acute coronary syndrome despite having been administered 7,500 units of unfractionated heparin and being given 325 mg of aspirin and 60 mg of prasugrel prior to the procedure. The thrombi were managed effectively by giving an intra-coronary high bolus dose of tirofiban (25 mcg/kg) without the need for catheter thrombus extraction. Tirofiban intra-venous infusion was maintained for 18 hours, and the patient was discharged in stable condition on the third day. Importantly there is no controlled study on upstream administration of glycoprotein IIb/IIIa inhibitors in addition to the newer more potent anti-platelet agents in patients with unprotected distal left main disease presenting with non ST-segment elevation acute coronary syndrome, nor is there any data on safety and efficacy of mandatory usage of injectable anti-platelet agents at the start of a procedure in a catheterization laboratory in such a setting

    Full Text Available Mucoceles of the paranasal sinuses are slowly growing, epithelium-lined cystic lesions with sterile content. When the mucocele content becomes infected with a bacterial super-infection, the lesion is defined as mucopyocele. Mucoceles or mucopyoceles are commonly located in the frontal and anterior ethmoidal sinuses and can manifest with ocular signs and symptoms, mostly proptosis. In this report, we demonstrate a case of bilateral ethmoidal mucopyocele in a 53-year-old female who presented with reduced vision, diplopia, and proptosis. Computed tomography (CT scanning of the paranasal sinuses revealed cystic lesions filling the maxillary sinuses and anterior ethmoidal cells bilaterally and causing erosion in the walls of the sinuses. After marsupialization of the mucopyoceles was performed by endoscopic sinus surgery, the symptoms of the patient recovered rapidly. (Turk J Ophthalmol 2011; 41: 354-6

    Color Doppler US (CDUS) has been used for evaluation of cerebral venous sinuses in neonates. However, there is very limited information available regarding the appearance of superficial and deep normal cerebral venous sinuses using CDUS and the specificity of the technique to rule out disease. To determine the specificity, inter-modality and inter-reader agreement of color Doppler US (CDUS). To evaluate normal cerebral venous sinuses in neonates in comparison to MR venography (MRV). Newborns undergoing a clinically indicated brain MRI were prospectively evaluated. All underwent a dedicated CDUS of the cerebral venous sinuses within 10 h (mean, 3.5 h, range, and 2-7.6 h) of the MRI study using a standard protocol. Fifty consecutive neonates participated in the study (30 males [60%]; 25-41 weeks old; mean, 37 weeks). The mean time interval between the date of birth and the CDUS study was 19.1 days. No cases showed evidence of thrombosis. Overall agreement for US reading was 97% (range, 82-100%), for MRV reading, 99% (range, 96-100%) and for intermodality, 100% (range, 96-100%). Excellent US-MRI agreement was noted for superior sagittal sinus, cerebral veins, straight sinus, torcular Herophili, sigmoid sinus, superior jugular veins (94-98%) and transverse sinuses (82-86%). In 10 cases (20%), MRV showed flow gaps whereas normal flow was demonstrated with US. Visualization of the inferior sagittal sinus was limited with both imaging techniques. Excellent reading agreement was noted for US, MRV and intermodality. CDUS is highly specific to rule out cerebral venous thrombosis in neonates and holds potential for clinical application as part of clinical-laboratory-imaging algorithms of pre/post-test probabilities of disease.

    Diseases of nose and paranasal sinuses can complicate to involve the orbit and other surrounding structures because of their close proximity. These diseases are usually infective or can be neoplastic in origin. Method: All the patients presenting in ENT or Eye Departments of Ayub Teaching Hospital during the one year study period who had complicated nose or paranasal sinus disease were included in the study. A detailed history and examination followed by CT scanning and laboratory investigations to assess the type and extent of the disease, was carried out. Results: Infections were the most common cause of complicated sinus disease 11 (75%). The rest of the 4 (25%) cases were tumours. 12 (80%) of the cases presented with proptosis. In 1 of these 12 cases, there was complete blindness. In 2 (13%) of the cases there was only orbital cellulitis. Two of these patients had facial swelling and 2 had nasal obstruction and presented as snoring. Two patients presented with history of weight loss and these patients had malignant tumour of the paranasal sinuses. One patient presented with early signs of meningitis. In 1 case sub periosteal scalp abscess (Pott's puffy tumour) was the only complication noted. Conclusion: Nose and paranasal sinus diseases can complicate to involve mostly the orbit, but sometimes brain, meninges and skull bones can also get involved. (author)

    Trichomonal disease typically involves the genital and occasionally respiratory tracts. Although exposure of the upper respiratory tract to infected genital secretions is not uncommon with contemporary sexual practices, trichomonal sinus disease has been rarely described. The present report describes the case of a healthy 17-year-old male admitted to an intensive care unit following multiple trauma, who developed purulent sinusitis on the 4th day of hospitalization. Numerous trichomonads were noted on microscopic examination of sinus aspirate. Further investigation revealed orofacial sexual exposure of the patient to a partner with trichomoniasis. The patient's sinusitis resolved following a course of parenteral metronidazole-containing antibiotics.

    To specify CT scan roll in diagnosis of radicullar cyst invading maxillary sinus. Two cases of 23 and 34-year-old men presented with facial injury and sinusitis was explored by CT scan. CT scan showed in both patients a cystic lesion, developing into the maxillary sinus around a tooth apex and limits by a double dense thin rim. CT scan permits diagnosis of radicular cyst invading maxillary sinus, in the event of obscured maxillary sinus, when double dense thin rim corresponding to the repulsed wall of the sinus is looking.

    The symptoms of a previously healthy 14-year-old female with an initial history of tooth pain and swelling of the left maxillary evolved to a progressive headache and altered neurological findings characterized by auditory hallucinations, sleep disturbances, and aggressiveness. She was brought to the emergency department after 21 days of the initial symptoms. An initial computed tomography (CT) scan showed frontal subdural empyema with bone erosion. The symptoms continued to evolve to brain herniation 24 hours after admission. A second CT scan showed a left internal jugular vein thrombosis. The outcome was unfavorable and the patient died on the second day after admission. The autopsy findings depicted rarefaction of the cranial bone at the left side of the frontal sinus, and overt meningitis. The severe infection was further complicated by thrombophlebitis of the left internal jugular vein up to the superior vena cava with septic embolization to the lungs, pneumonia, and sepsis. This case report highlights the degree of severity that a trivial infection can reach. The unusual presentation of the sinusitis may have wrongly guided the approach of this unfortunate case.

  17. Maxillary sinus augmentation

    Full Text Available Placing dental implants in the maxillary posterior region can be both challenging and un-nerving for a regular implant dentist who is not well versed with advanced surgical procedures. It is vital for a general dentist to understand the fundamentals of bone grafting the maxillary sinus if he/she is really committed to providing the best health care for their patients. The dental practice is seeing an increasing group of patients who are living longer, and this group of older baby boomers often has an edentulous posterior maxilla either unilateral or bilateral. When edentulous, the posterior maxilla more likely has diminished bone height, which does not allow for the placement of dental implants without creating additional bone. Through grafting the maxillary sinus, bone of ideal quality can be created (allowing for placement of dental implants, which offer many advantages over other tooth replacement modalities. The sinus graft offers the dental patient a predictable procedure of regenerating lost osseous structure in the posterior maxilla. This offers the patient many advantages for long-term success. If dentists understand these concepts, they can better educate their patients and guide them to have the procedure performed. This article outlines bone grafting of the maxillary sinus for the purpose of placing dental implants. This review will help the readers to understand the intricacies of sinus augmentation. They can relate their patient's condition with the available literature and chalk out the best treatment plan for the patient, especially by using indirect sinus augmentation procedures which are less invasive and highly successful if done using prescribed technique.

    The aim of this study was to review the imaging features in acute (< 24 h) basilar artery thrombosis. CT and MR studies in 11 patients with clinical diagnosis of acute basilar artery thrombosis were retrospectively reviewed. MR angiography was obtained in 4 patients. Correlation with clinical symptoms was performed. Multiple cranial nerve palsies and hemiparesis were the most common clinical symptoms at presentation. CT revealed hyperdense basilar arteries (n = 7) and hypodensities in the posterior circulation territory (n = 8). In one instance, the infarction was hemorrhagic. MR imaging showed absence of flow void within the basilar in 6 patients and MRA (using both PC and TOF techniques) confirmed absence of blood flow in 4 basilar arteries. One week after presentation, 5 patients died. Autopsy was obtained in 1 case and confirmed the diagnosis of basilar artery thrombosis. Basilar artery thrombosis has fairly typical imaging features by both CT and MR. MRA may be used to confirm the diagnosis. Prompt recognition may lead to early thrombolytic treatment and may improve survival. (orig.)

    Neuroradiological techniques were used to elucidate pathophysiology of recurrent cerebral thrombosis. Twenty-two patients with cerebral thrombosis who suffered a second attack under stable conditions more than 22 days after the initial stroke were studied. Hypertension, diabetes mellitus, and hypercholesterolemia were also seen in 20, 8, and 12 patients, respectively. The patients were divided into three groups according to their symptoms: (I) symptoms differed between the first and second strokes (n=12); (II) initial symptoms were suddenly deteriorated (n=6); and (III) symptoms occurring in groups I and II were seen (n=4). In group I, contralateral hemiparesis or suprabulbar palsy was often associated with the initial hemiparesis. The time of recurrent stroke varied from 4 months to 9 years. CT and MRI showed not only lacunae in both hemispheres, but also deep white-matter ischemia of the centrum semi-ovale. In group II, hemiparesis or visual field defect was deteriorated early after the initial stroke. In addition, neuroimaging revealed that infarction in the posterior cerebral artery was progressed on the contralateral side, or that white matter lesion in the middle artery was enlarged in spite of small lesion in the left cerebral hemisphere. All patients in group III had deterioration of right hemiparesis associated with aphasia. CT, MRI, SPECT, and angiography indicated deep white-matter ischemia caused by main trunk lesions in the left hemisphere. Group III seemed to be equivalent to group II, except for laterality of the lesion. Neuroradiological assessment of the initial stroke may help to predict the mode of recurrence, although pathophysiology of cerebral thrombosis is complicated and varies from patient to patient.

  20. Numerical simulations of thrombosis

    Naveen Kumar G Ramunigari

    2013-01-01

    Full Text Available Background: Mathematical approaches for biological events have gained significant importance in development of biomedical research. Deep vein thrombosis (DVT is caused by blood clot in veins deeply rooted in the body, resulting in loss of blood, pain, and numbness of the body part associated with that vein. This situation can get complicated and can be fatal, when the blood clot travels to other parts of the body which may result in pulmonary embolism (PE. PE causes approximately 300,000 deaths annually in the United States alone. Materials and Methods: We are trying to propose a computational approach for understanding venous thrombosis using the theory of fluid mechanics. In our study, we are trying to establish a computational model that mimics the venous blood flow containing unidirectional venous valves and will be depicting the blood flow in the veins. We analyzed the flow patterns in veins, which are included with lump like substances. This lump like substances can be clots, tissue debris, collagen or even cholesterol. Our study will facilitate better understanding of the biophysical process in case of thrombosis. Results: The predicted model analyzes the consequences that occur due to the clot formations in veins. Knowledge of Navier-Stokes equations in fluid dynamics along with the computational model of a complex biological system would help in diagnosis of the problem at much faster rate of time. Valves of the deep veins are damaged as a result of DVT, with no valves to prevent deep system reflux, the hydrostatic venous pressure in the lower extremity increases dramatically. Conclusion: Our model is used to determine the effects of an interrupted blood flow as a result of thrombin formation, which might result in disturbed systemic circulation. Our results indicated a positive inverse correlation exists between clots and the flow velocity. This would support medical practitioners to recommend faster curing measures.

    Rivara, Andrew; James, Andra H

    2018-06-01

    Management of heavy menstrual bleeding (HMB) in a woman with a history of thrombosis, or who is otherwise at high risk of thrombosis, or who takes medications for anticoagulation can present a challenge to health care providers. The goal of treating HMB is to reduce menstrual blood loss. First-line therapy is typically hormonal, and hormonal therapy can be contraindicated in women with a history of thrombosis unless they are on anticoagulation. As 70% of women on anticoagulation experience HMB, successful management of HMB may involve a modification in the anticoagulation or antiplatelet regimen, hormonal therapy tailored to the patient's situation, and/or surgical therapy.

    The average time spent playing video games is increasing. Prolonged immobility associated with gaming may therefore be an important risk factor for venous thromboembolism. We report a case of deep vein thrombosis associated with prolonged playing of PlayStation® games. A 31-year-old Caucasian man, an exterior painter, presented with a three-day history of left leg pain and swelling after playing PlayStation® games for almost eight hours a day for four consecutive days. Doppler ultrasound of the left leg confirmed extensive left leg deep venous thrombosis requiring thrombolysis and anticoagulation. Video gaming should be considered a risk factor for venous thromboembolism. Further studies are needed to estimate the degree of risk associated with prolonged periods of playing video games, and education for preventing venous thrombosis should be provided to gamers.

    2000-01-01

    The purpose of this study is to evaluate the characteristic MR findings of sacrococcygeal pilonidal is simus. Eight MR images of pathologically proven sacrococcygeal pilonidal sinus were retrospectively reviewed [M:F 7:1 ; age range 9-41(median, 17) years]. In all cases, a sacrococcygeal mass was present. Five of the eight patients experienced pain, and in three was discharge. MR findings were evaluated with regard to the location and extent of the lesion, and the presence of sinus or cyst, and the results were compared with the pathologic findings. According to the clinical manifestations, each case was assigned to one of four groups: the first type (n=3) showed dermal thickening with subcutaneous fatty infiltration of the ipsilateral natal cleft while pathologically, a follicular cyst with dermal fibrosis and multiple fatty lobules with fibrous septa were found to be present. In the secone type (n=3), fluid was observed in the sinus tract, while the pathologic findings demonstrated the presence of an abscess in this area. In the third type (n=1), a cystic lesion with air-fluid level was present; pathologically, an abscess was revealed. The fourth type (n=1) showed only a low signal intensity sinus tract on both T1 and T2-weighted images, while the pathologic findings indicated the presence of hairs and follicles within the tract. The MR findings of sacrococcygeal pilonidal sinus depend on the clinical mainfestation and include subcutaneous fatty infiltration, a sinus tract with or without fluid retention, and a cystic lesion with air fluid level. These findings could be helpful for differentiating between this and other sacrococcygeal lesions

  15. Value of imaging modalities in sinus tarsi syndrome

    1989-01-01

    Sinus tarsi syndrome consists of ankle pain, giving way of the ankle, and tenderness over the sinus tarsi after acute ankle injury (usually inversion). Plan radiographic evaluation is unrewarding. This paper reports on stress CT scanning performed in 25 patients with sinus tarsi syndrome; 18 of these patients also underwent MR imaging; and all patients had routine radiographs. No consistent significant abnormalities were seen on CT. Ligamentous injury of the calcaneofibular or talocalcaneal ligament was suggested on MR images in six cases. Therefore, CT was not helpful in evaluating sinus tarsi syndrome, and the MR findings were present in only one-third of cases, suggesting either that MR imaging is not at present sufficiently accurate to detect all abnormalities or ligamentous injury is not the underlying cause for sinus tarsi syndrome

    A rare case of dural arteriovenous fistula (DAVF) in the superior sagittal sinus (SSS), the transverse sinus and the sigmoid sinus is reported. A 64-year-old man, who had had an episode of temporary visual disturbance after moderate fever for a week about 20 years before, was aware of loss of visual acuity and reduced field of view in the right eye. When he was introduced to our outpatient service, increased intracranial pressure (ICP) was detected by lumbar puncture. Cerebral angiograms showed bilateral DAVFs both in the posterior fossa and the SSS concomitant with thrombosis in the transverse sinus, sigmoid sinus and SSS. Afterwards, endovascular transarterial embolization through bilateral occipital, posterior auricular and left middle meningeal, superior temporal arteries was carried out. In addition, transvenous thrombolytic therapy using a catheter inserted into SSS resulted in the improvement of his visual problems. Although he was discharged at once, he was readmitted to our department with Foster Kennedy syndrome and increased ICP. Cerebral angiograms showed recurrence of both DAVF and sinus thrombosis. Transarterial embolization was performed again resulting in a significant reduction of DAVF, and his visual acuity was recovered to a moderate degree. The origin of DAVF is still controversial. Although two theories, "congenital" and "acquired", are put forward, it has been thought that both factors play important roles. In our case, the patient had stenosis in the jugular canal portions of the sigmoid sinus. In addition, sinus thrombosis seemed to have occurred. It is thought that increased intrasinus pressure may have lead to communication with surrounding arteries through existing dural vessels. We applied transvenous thrombolytic therapy in this case. Our result suggests that we should consider this therapy for some cases of DAVF.

    To identify the relationship between hemoglobin (Hgb) or hematocrit (Hct) level and dural sinus density using unenhanced computed tomography (UECT). Patients who were performed UECT and had records of a complete blood count within 24 hours from UECT were included (n=122). We measured the Hounsfield unit (HU) of the dural sinus at the right sigmoid sinus, left sigmoid sinus and 2 points of the superior sagittal sinus. Quantitative measurement of dural sinus density using the circle regions of interest (ROI) method was calculated as average ROI values at 3 or 4 points. Simple regression analysis was used to evaluate the correlation between mean HU and Hgb or mean HU and Hct. The mean densities of the dural sinuses ranged from 24.67 to 53.67 HU (mean, 43.28 HU). There was a strong correlation between mean density and Hgb level (r=0.832) and between mean density and Hct level (r=0.840). Dural sinus density on UECT is closely related to Hgb and Hct levels. Therefore, the Hgb or Hct levels can be used to determine whether the dural sinus density is within the normal range or pathological conditions such as venous thrombosis.

  20. Successful endoscopic management with Mitomycin C application for sinusitis with orbital cellulitis

    Directory of Open Access Journals (Sweden)

    Anil S Harugop

    2013-01-01

    Full Text Available Background: Sinusitis with orbital complication is a potentially fatal disease that has been known since the days of Hippocrates. Primary sinus infection is the most common cause of orbital cellulitis. It is an emergency that threatens not only vision but also life from complications such as meningitis, cavernous sinus thrombosis, and brain abscess. Surgical intervention is mandatory whenever antibiotic treatment fails. There are two surgical options for the drainage, an external approach via a Lynch incision and an intranasal endoscopic procedure. Materials and Methods: Five patients with orbital cellulitis secondary to acute on chronic rhinosinusitis were included in the study from the period of 2010 - 2011. All five patients did not respond to medical management and hence underwent endoscopic sinus surgery with treatment of orbital pathology. At the end of the surgical procedure Mitomycin C in a concentration of 0.4mg/ml was applied with a cottonoid for a period of 4 minutes to prevent chance of adhesion formation. Results: In this series 3 females and 2 male patient with orbital cellulitis secondary to acute on chronic rhinosinusitis underwent endoscopic sinus surgery with treatment of orbital pathology. All 5 patients showed subjective and objective improvement within one week of endoscopic management. Conclusion: Though antibiotics have altered the course of sinusitis, its grave complications still persist in our environment. The excellent results and the absence of any major complications of endoscopic sinus surgery and drainage of abscess with application of Mitomycin C can be recommended as the preferred surgical technique.

    To investigate cerebral venous thrombosis (CVTR) clinical presentations, risk factors, and response to treatment in Saudi Arabia. Retrospective analysis of the King Farad Medical City, Riyadh, acute stroke database from April 2005 through February 2008 revealed 22 patients with CVTR. Hyper coagulable work-up and neuroimaging were performed. Sixteen patients were female (72.7%), and the median age was 35 years. Clinical presentations included: headache (77.3%), seizures (54.5%), focal neurological signs (54.5%), and decreased level of consciousness (50%). Over two-thirds (n=11; 69%) of female patients had a history of oral contraceptive use, which was the most common risk factor. Protein S deficiency (n=3), anti phospholipid antibody syndrome secondary to systemic lupus erythematosus (SLE) (n=1), rhinocerebral mucormycosis (n=1), leukemia (n=1), non-Hodgkin's lymphoma (n=1), sepsis (n=1), and unknown (n=6) were causes. Affected areas included superior sagittal (n=13), transverse (n=16), sigmoid (n=14), straight (n=6), and cavernous sinus (n=1); internal cerebral vein (n=2); vein of Galen (n=3); cortical veins (n=10); and internal jugular vein (n=12). Two patients had quadriparesis, and 2 patients died. The remainder (n=18, 81.8%) improved. Bilateral hemorrhagic presentation or venous infarction, deep venous system thrombosis, and underlying malignancy had less favorable results. Presentations in our series were similar to those in other reports, although altered consciousness and seizures were more common. Cortical vein involvement was also higher than commonly reported. Oral contraceptive use was a primary risk factor in female patients. Outcomes were favorable in 81.8% of patients. (author)

    Full Text Available Pyriform sinus fistula is a rare clinical entity and the precise origin remains controversial. The fistula is discovered among patients with acute suppurative thyroiditis or deep neck infection of the left side of the neck and is usually located in the left pyriform sinus. To the best of our knowledge, only a single tract has been reported to be responsible for pyriform sinus fistula infection. We present a case of a 13-year-old female patient with a pyriform sinus fistula that caused a deep infection of the left side of the neck and showed double-tract involvement discovered during surgical resection of the entire fistula. Both tracts arose around the pyriform sinus and terminated at the upper portion of the left lobe of the thyroid.

    Full Text Available Dental implant associated rehabilitation of the posterior maxilla poses unique challenge owing to the presence of pneumatized sinuses and atrophied alveolar bone. Sinus augmentation procedure to manage expanded sinuses frequently results in membrane tear resulting in unfavorable stabilization of the graft and associated bone regeneration. Simultaneous implant placement during sinus augmentation procedures frequently requires a minimal alveolar bone height, which when not present forces clinician to defer implant placement resulting in extended treatment duration and multiple surgical appointments. The present case report is about a piezosurgery assisted lateral wall osteotomy approach for sinus augmentation associated with membrane repair with simultaneous implant placement in the posterior maxilla.

    As anorexia patients always go to the psychiatric clinic, little is concerned about the occurrence of sinus bradycardia in these patients for cardiologists and psychiatrists. The aim of this paper is to discuss the relationship between anorexia and sinus bradycardia, and the feature analysis, differential diagnosis and therapeutic principles of this type of sinus bradycardia. We report a case of sinus bradycardia in an anorexia patient with the clinical manifestations, laboratory exams, auxiliary exams, therapeutic methods, and her prognosis, who was admitted to Peking University Third Hospital recently. The patient was a 19-year-old female, who had the manifestation of anorexia. She lost obvious weight in a short time (about 15 kg in 6 months), and her body mass index was 14.8 kg/m(2). The patient felt apparent palpitation, chest depression and short breath, without dizziness, amaurosis or unconsciousness. Vitals on presentation were notable for hypotension, and bradycardia. The initial exam was significant for emaciation, but without lethargy or lower extremity edema. The electrocardiogram showed sinus bradycardia with her heart rate being 32 beats per minute. The laboratory work -up revealed her normal blood routine, electrolytes and liver function. But in her thyroid function test, the free thyroid (FT) hormones 3 was 0.91 ng/L (2.3-4.2 ng/L),and FT4 was 8.2 ng/L (8.9-18.0 ng/L), which were all lower; yet the thyroid stimulating hormone (TSH) was normal 1.48 IU/mL (0.55-4.78 IU/mL). Ultrasound revealed her normal thyroid. Anorexia is an eating disorder characterized by extremely low body weight, fear of gaining weight or distorted perception of body image, and amenorrhea. Anorexia patients who lose weight apparently in short time enhance the excitability of the parasympathetic nerve, and inhibit the sympathetic nerve which lead to the appearance of sinus bradycardia, and functional abnormalities of multiple systems such as hypothyroidism. But this kind of sinus

    Over the past 10 years more than 700 cases of brucellosis have been reported in Kosovo, which is heavily oriented towards agriculture and animal husbandry. Here, brucellosis is still endemic and represents an uncontrolled public health problem. Human brucellosis may present with a broad spectrum of clinical manifestations; among them, vascular complications are uncommon. Hereby we describe the case of a 37-year-old male patient with brucellosis complicated by deep vein thrombosis on his left leg.

    Deep vein thrombosis (DVT) is a dangerous complication that may present after elective foot surgery. Because of the frequency with which DVT occurs in the elderly patient, as well as in the podiatric surgical population, the podiatrist should be acquainted with this entity. A review of the diagnosis, treatment, prevention, and the role of podiatry in the management of DVT is discussed in this paper.

    Fat density in the dural sinus on computed tomography (CT) is described in eight cases. Of the eight cases, five had fat deposit in the torcular Herophili, and three in the superior sagittal sinus. This finding was incidentally found by CT and there was no common underlying disease in these cases. It is suggested that this finding represents normal adipose tissue in the dural sinus. (orig.)

    Plantar vein thrombosis is a rare condition, with only a handful of cases reported in the literature. The cause is unknown; however, the disease has been attributed to prior surgery, trauma, and paraneoplastic conditions. We present a case of a 32-year-old female runner with plantar vein thrombosis diagnosed on contrast-enhanced MRI and confirmed on ultrasound. The symptoms resolved with conservative treatment and evaluation revealed the presence of a prothrombin gene mutation and use of oral contraceptive pills. To our knowledge, this is the first case of plantar vein thrombosis diagnosed initially by MRI. Moreover, this case suggests that plantar vein thrombosis should be considered in patients with hypercoagulable states and plantar foot pain. (orig.)

    Venous thromboembolism (VTE) is a complication that frequently occurs in patients with neoplastic diseases. Several models have therefore been developed to identify patient subgroups diagnosed with cancer who are at increased risk of developing VTE. The most common forms of thromboembolic episodes are deep vein thrombosis in the lower limbs and pulmonary thromboembolism. However, venous thrombosis is also diagnosed in atypical locations. There are few revisions of unusual cases of venous thrombosis. In most cases, VTE occurs in the upper limbs and in the presence of central venous catheters, pacemakers and defibrillators. We present the case of a patient diagnosed with breast cancer and treated with surgery, chemotherapy and radiation therapy who developed a thrombosis in the upper limbs (brachial and axillary).

    Combined oral contraceptive (COC) use has been associated with venous thrombosis (VT) (i.e., deep venous thrombosis and pulmonary embolism). The VT risk has been evaluated for many estrogen doses and progestagen types contained in COC but no comprehensive comparison involving commonly used COC is available. To provide a comprehensive overview of the risk of venous thrombosis in women using different combined oral contraceptives. Electronic databases (Pubmed, Embase, Web of Science, Cochrane, CINAHL, Academic Search Premier and ScienceDirect) were searched in 22 April 2013 for eligible studies, without language restrictions. We selected studies including healthy women taking COC with VT as outcome. The primary outcome of interest was a fatal or non-fatal first event of venous thrombosis with the main focus on deep venous thrombosis or pulmonary embolism. Publications with at least 10 events in total were eligible. The network meta-analysis was performed using an extension of frequentist random effects models for mixed multiple treatment comparisons. Unadjusted relative risks with 95% confidence intervals were reported.Two independent reviewers extracted data from selected studies. 3110 publications were retrieved through a search strategy; 25 publications reporting on 26 studies were included. Incidence of venous thrombosis in non-users from two included cohorts was 0.19 and 0.37 per 1 000 person years, in line with previously reported incidences of 0,16 per 1 000 person years. Use of combined oral contraceptives increased the risk of venous thrombosis compared with non-use (relative risk 3.5, 95% confidence interval 2.9 to 4.3). The relative risk of venous thrombosis for combined oral contraceptives with 30-35 μg ethinylestradiol and gestodene, desogestrel, cyproterone acetate, or drospirenone were similar and about 50-80% higher than for combined oral contraceptives with levonorgestrel. A dose related effect of ethinylestradiol was observed for gestodene

    Full Text Available Introduction: Sinus lift is a process that could be performed by two methods. In the closed sinus lift, hybrid materials enter a suitable position through a created cavity. Afterwards, the materials are pressed without damaging the sinus membrane, and the implants are usually placed at the same time. Closed sinus lift is carried out via osteotomy and piezosurgery, and each of the techniques has certain advantages and limitations. The present study aimed to compare the clinical results of closed sinus lift using the summers osteotomy and piezosurgery. Materials and Methods: In this study, 20 patients requiring dental implants in the posterior segment of the maxilla via sinus lift surgery were randomly divided into two groups. The first group received piezosurgery, and the second group underwent summers osteotomy for sinus lift. Postoperative Schneiderian membrane perforation, inflammation, pain, bone gain, and bone loss were compared between the groups six months after the surgery using Mann-Whitney U test and two-sample t-test. Results: In the groups receiving piezosurgery and summers osteotomy, mean sinus lift was 3.6±0.9 and 4.0±2.2 mm, pain score was 1.1±1.2 and 0.9±0.8, bone gain was 2.2±0.8 and 3.1±1.3 mm, and crestal bone loss was 1.1±1.2 and 0.9±0.8 mm, respectively. Moreover, no Schneiderian membrane perforation was observed in the two methods, and the differences between the groups were not considered significant (P>0.05. Conclusion: According to the results, the clinical outcomes of piezosurgery in sinus lift are similar to those of summers osteotomy. Therefore, piezosurgery could be a proper alternative to summers osteotomy in sinus lift surgery.

    2011-01-01

    Full Text Available Introduction. Primary venous tumours are a rare cause of deep vein thrombosis. The authors present a case where the definitive diagnosis was delayed by inconclusive complementary imaging. Clinical Case. A thirty-seven-year-old female presented with an iliofemoral venous thrombosis of the right lower limb. The patient had presented with an episode of femoral-popliteal vein thrombosis five months before and was currently under anticoagulation. Phlegmasia alba dolens installed progressively, as thrombus rapidly extended to the inferior vena cava despite systemic thrombolysis and anticoagulation. Diagnostic imaging failed to identify the underlying aetiology of the deep vein thrombosis. The definitive diagnosis of primary venous leiomyosarcoma was reached by a subcutaneous abdominal wall nodule biopsy. Conclusion. Primary venous leiomyosarcoma of the iliac vein is a rare cause of deep vein thrombosis, which must be considered in young patients with recurrent or refractory to treatment deep vein thrombosis.

    Full Text Available ABSTRACT: CONTEXT: Umbilical cord thrombosis is related to greater fetal and perinatal morbidity and mortality. It is usually associated with umbilical cord abnormalities that lead to mechanical compression with consequent vascular ectasia. Its correct diagnosis and clinical management remains a challenge that has not yet been resolved. CASE REPORT: This study reports a case of umbilical artery thrombosis that occurred in the second half of a pregnancy. The umbilical cord was long, thin and overly twisted and the fetus presented severe intrauterine growth restriction. The clinical and histopathological findings from this case are described. CONCLUSIONS: This case report emphasizes the difficulty in diagnosing and clinically managing abnormalities of intrauterine life with a high chance of perinatal complications.

    Sphenoidal aspergillosis is an unusual cause of sella turcica enlargement. Pituitary abscess secondary to Aspergillus had been reported. In the present case, a woman with sphenoid sinus aspergillosis mimiced a pituitary tumor. This patient survived her infection with intact pituitary function following a transsphenoidal approach. No postoperative amphotericine-B and 5-fluorocytosine were necessary. CT scan revealed a mass occupying the sphenoid sinus extending to the sella turcica. Factors that should alert the clinican to the presence of a sphenoidal and pituitary abscess in a patient with sella turcica enlargement are prior episodes of sinusitis, meningitis and immunosuppression and, as in the present case, hyperglycemia.

    Full Text Available The aetiology of fungal sinusitis is diverse and changing. Aspergillus species has been the most common cause for fungal sinusitis, especially in dry and hot regions like India. Trichosporon species as a cause for fungal sinusitis has been very rarely reported the world over. Here, we report a rare case of allergic fungal sinusitis caused by Trichosporon inkin in a 28-year-old immunocompetent woman. Bilateral nasal obstruction, nasal discharge and loss of smell were her presenting complaints. Diagnostic nasal endoscopy showed bilateral multiple polyps. Functional endoscopic sinus surgery was performed and many polyps were removed. Based on mycological and histopathological studies, the pathogen was identified as T. inkin.

    2010-09-01

    A mucocele is a mucus-containing sac lined with epithelium that arises within a sinus when its drainage is compromised. The frontal sinus is the most common location, with frontal mucocele development occurring when the nasofrontal duct becomes obstructed because of polyps, bone tumors, prior surgery, sinusitis, trauma, or anatomic variation. We report an unusual case of a sterile pediatric frontal mucocele presenting as a slowly enlarging forehead mass due to a bifid frontal sinus septum. A 9-year-old girl presented to the craniofacial clinic for evaluation of a right frontal mass that had been slowly growing over the past year. She was otherwise healthy and had no history of previous trauma or sinus infections. Computed tomography (CT) scan results revealed a localized frontal fluid collection with protrusion and thinning of the anterior frontal bone between 2 midline bony septii. Surgical cranialization of the frontal sinus was performed. The anatomy of her lesion seen both on CT scan and intraoperatively likely explains this unusual case presentation. Instead of the usual inciting event of an intact frontal sinus drainage system becoming blocked, this patient seemed to have a primary developmental lack of any drainage system that led to her mucocele. During formation of her frontal sinus, she developed a bifid septum within the midline that excluded a portion of her frontal sinus from the lateral nasofrontal ducts. With mucus-producing epithelium trapped within these bony confines, pressure began to mount with expansion and thinning of the bone both anteriorly and posteriorly. The lack of any infectious symptoms and sterile culture results may support that this space developed primarily and was never in continuity with the external drainage system. Only 4 other patients have been reported with asymptomatic forehead swelling as the only presenting symptom, with the age ranging from 33 to 79 years. This patient represents the first clinical report of a congenital

    Nasofrontal dermal sinuses are very rare and generally occur in children. This congenital malformation can be revealed by midface swelling, which can be complicated by local infection or neuromeningitis. Such complications make the dermal sinus a life-threatening disease. Two cases of nasofrontal dermal sinuses are reported in this work. The first case is an 11-month-old girl who presented with left orbitonasal soft tissue swelling accompanied by inflammation. Physical examination found fever, left orbitonasal thickening, and a puncture hole letting out pus. Computed tomography revealed microabscesses located at the left orbitonasal soft tissues, a frontal bone defect, and an intracranial cyst. Magnetic resonance imaging showed the transosseous tract between the glabella and the brain and affirmed the epidermoid nature of the intracranial cyst. The second case is a 7-year-old girl who presented with a nasofrontal non-progressive mass that intermittently secreted a yellow liquid through an external orifice located at the glabella. MRI revealed a cystic mass located in the deep layer of the glabellar skin related to an epidermoid cyst with a nasofrontal dermal sinus tract. In both cases, surgical excision was performed, and pathological confirmation was made for the diagnoses of dermal sinuses. The postoperative course was favorable. Through these cases, the authors stress the role of imaging methods in confirming the diagnosis and looking for associated cysts (dermoid and epidermoid) to improve recognition of this rare disease. Knowledge of the typical clinical presentations, imaging manifestations, and most common sites of occurrence of this malformation are needed to formulate a differential diagnosis.

    Full Text Available We present a case of acute mesenteric venous thrombosis after a long distance flight in a traveller presenting with abdominal pain, diarrhoea and vomiting within 48 h of prolonged immobility situation. Venous thrombosis in the lower limbs and venous thromboembolism has been clearly associated with prolonged air travel (economy class syndrome. Thrombosis was diagnosed by computed tomography of the abdomen, and after starting anticoagulant therapy with acenocumarol, symptoms yielded completely in a few weeks. The study of thrombophilia was negative, although the existence of two first-degree relatives (mother and grandmother with a history of venous thrombosis with a history of venous thrombosis makes it likely a situation of inherited thrombophilia. Although exceptional, mesenteric venous thrombosis should be considered in travellers with acute abdominal pain after prolonged air travel when there are thrombophilic conditions.

    2006-01-01

    The purpose of the study was to determine the incidence and risk factors for venous thrombosis in patients with a peripherally inserted central catheter (PICC). A retrospective study of all upper extremity venous duplex scans was carried out in the Vascular Medicine department from year 2000 to 2002 inclusive. A chart review of positive scans was undertaken to identify possible thrombotic risk factors. Of 317 upper extremity venous duplex scans carried out, 115, or 32%, were positive for upper extremity deep vein thrombosis. Three main risk factors were identified - presence of a central line, malignancy and administration of chemotherapy. PICC were the most common central line present. Symptomatic thrombosis occurred in 7% of PICC inserted for chemotherapy compared with 1% of PICC inserted for other reasons. Ten per cent of the patients receiving chemotherapy through a PICC developed a thrombosis. The post-thrombotic syndrome was infrequent following upper extremity deep vein thrombosis. Patients receiving chemotherapy through a PICC are at increased risk of thrombosis. There may be a role for prophylactic low-dose anticoagulation in these high-risk patients

    1989-01-01

    In the period 1983 to 1985, 66 patients presented to six Japanese university hospitals with squamous cell carcinoma of the maxillary sinus. Using self-administered questionnaires, a case-control study was conducted to examine history of nasal diseases, occupational exposures, and other possible risk factors for this disease. For each patient, two controls were selected from the general population, matched to the patient by sex, age (+/- 5 years), and district of residence. A history of chronic sinusitis was associated with a 2.3-fold increase in risk (p = 0.05). A high relative risk was also observed in males with an occupational history of woodworking or joinery, particularly when these jobs involved sanding or lathing practices (RR = 7.5, p = 0.02). No association between cigarette smoking and maxillary sinus cancer was observed in this study and no evidence was found that indoor air pollution in the home is involved in cancer development.

  2. Sinusitis with eosinophilic otitis media

    2007-01-01

    Eosinophilic otitis media is an intractable inflammation of the middle ear combined with bronchial asthma. According to a national epidemiological investigation on eosinophilic otitis media, it is assumed that eosinophilic otitis media are combined with sinusitis in about 74% of their cases. On the other hand, organizational images of eosinophilic otitis media and eosinophilic sinusitis are similar, and steroid therapy is effective together, and it is thought that they are involved in the idea of one airway one disease, but the details of sinusitis combined with the eosinophilic otitis media are unidentified. Therefore, we examined the kinds of the sinusitis combined with eosinophilic otitis media. We diagnosed 18 cases (male: 2 cases, female: 16 cases) (average age: 54.6 years old) as eosinophilic otitis media according to the diagnostic criteria. And, by the CT views of a paranasal sinus, blood tests, existence of the nasal polyp, etc, we investigated the kinds of sinusitis combined with eosinophilic otitis media. It turned out that bronchial asthma was combined with eosinophilic otitis media in 17 of 18 cases (airway hypersensitivity did sthenia of one case, but the asthma did not yet developed), and 6 cases were combined with aspirin induced asthma (AIA), and 3 cases were combined with Churg-Strauss syndromes (CSS). 10 case (55.6%) of 17 eosinophilic otitis media were combined with eosinophilic sinusitis. And 4 cases (22.2%) of 17 eosinophilic otitis media were combined with chronic sinusitis, 4 cases (22.2%) of 17 eosinophilic otitis media were not combined with sinusitis. We concluded that eosinophilic otitis media was not always combined with eosinophilic sinusitis. The idea of one airway one disease was not applied to this examination. (author)

    Eosinophilic otitis media is an intractable inflammation of the middle ear combined with bronchial asthma. According to a national epidemiological investigation on eosinophilic otitis media, it is assumed that eosinophilic otitis media are combined with sinusitis in about 74% of their cases. On the other hand, organizational images of eosinophilic otitis media and eosinophilic sinusitis are similar, and steroid therapy is effective together, and it is thought that they are involved in the idea of one airway one disease, but the details of sinusitis combined with the eosinophilic otitis media are unidentified. Therefore, we examined the kinds of the sinusitis combined with eosinophilic otitis media. We diagnosed 18 cases (male: 2 cases, female: 16 cases) (average age: 54.6 years old) as eosinophilic otitis media according to the diagnostic criteria. And, by the CT views of a paranasal sinus, blood tests, existence of the nasal polyp, etc, we investigated the kinds of sinusitis combined with eosinophilic otitis media.

    51 out-patients presenting with calf-vein thrombosis were randomized to treatment with heparin for five days or heparin with subsequent warfarin for three months. Among 23 patients in the warfarin-group no recurrence occurred, whereas 8 of the 28 patients (29%) in the non-warfarin group had recurrent thrombo-embolism during the first 90 days. It is concluded that patients with symptomatic calf-vein thrombi should be treated with both heparin and oral anticoagulation. In a prospective study of X-ray contrast media, post-phlebographic reactions occurred in 7 of 19 patients (37%) investigated with a high-osmolality contrast medium metrizoate whereas no such reaction occurred among 24 patients investigated with a low-osmolality contrast medium iohexol. Thus, low-osmolatily contrast media should preferably be used at phlebography. 396 out-patients with suspected venous thrombosis were investigated with the 99m Tc-plasmin test, physical examination and phlebography. The plasmin test has a high sensitivity (95%) but a low specificity (47%), and was frequently abnormal when clinical signs of inflammation were present. Clinical signs could not accurately predict if thrombosis was present, although subpopulations of patients with high or low probability of venous thrombosis could be identified. 112 patients with suspected DVT were investigated with thermography. Both sensitivity and specificity were low (77% and 66% respectively) and thermography therefore seems not to be useful in the diagnosis of symptomatic venous thrombosis. Long-term sequelae after a first episode of venous thrombosis are mostly mild as long as 6 years after the diagnosis. Venous function correlated to the extension of the thrombus but no to subjective symptoms. Clinical signs at diagnosis could not predict the late outcome. During the six years of follow-up, 28% of the patients had recurrent thrombosis. (158 refs.) (au)

    Radio-isotope diagnosis of peripheral venous thrombosis, using tracer doses of iodine-labelled fibrinogen, provides an important contribution to the solution of the worrying problem of pulmonary embolism due to latent phlebitis. This elegant and precise technique permits early diagnosis of venous thrombosis of the lower limbs at a subclinical stage. It has permitted determination of the frequency, both after surgery and after myocardial infarction, and above all, it provides an objective criterion for assessment of the efficacy of prophylactic measures proposed [fr

    We examined six patients with isolated venous thrombosis (n = 2), or venous thrombosis combined with sinus thrombosis (n = 4) (CVT). The clinical symptoms were non-specific (acute cephalea, paresis, epileptic seizure, progressive speech disorder). All examinations were performed on a 1.5 T system (Magnetom Symphony, Siemens, Erlangen, Germany), maximum gradient field strength 30 mT/m, minimal gradient rise time 450 {mu}s, according to the following protocol: Transverse T2-weighted turbo spin-echo (TSE), fluid attenuated inversion recovery (FLAIR), T1-weighted spin-echo (SE), before and after administration of contrast medium, T2*-weighted conventional gradient-echo (GRE), T2*-weighted spin-echo echo planar imaging (SE EPI), both without and with diffusion weighting as well as two-dimensional (2D) venous time-of-flight (TOF) MRA. The venous thromboses were best detectable in the T2*-weighted conventional GRE sequence in all patients. In two patients, the CVT was discernible only in this sequence. The sinus thrombosis was well discernible only in the T2*-weighted GRE sequence in only one case; in the remaining cases it was detectable only with difficulty. For these cases, other sequences such as SE, diffusion-weighted, or 2D-TOF-MRA sequence were superior. The T2*-weighted conventional GRE sequence was superior to the T2*-weighted SE EPI sequence in all patients. To sum up, it can be concluded, that T2*-weighted conventional GRE sequences are possibly the best method of detection of acute cortical vein thromboses. Therefore, it seems to be of benefit to integrate a T2*-weighted conventional GRE sequence into the MR-protocol for the diagnosis of isolated cortical vein thrombosis.

    The East African Early Miocene apes, or proconsulids, have often been considered to be among the earliest members of the Hominoidea, as defined by the divergence of the Cercopithecoidea, but this hypothesis is only weakly supported by available fossil evidence. The ethmofrontal sinus is one of a few morphological features that may link proconsulids with later hominoids. Here we present direct evidence of an ethmofrontal sinus in an early Oligocene stem catarrhine, Aegyptopithecus zeuxis. The ...

    Full Text Available The development of cerebral venous thrombosis (CVT as a secondary complication of Crohn's disease (CD seems to be rare, but it is generally accepted that the disease activity of CD contributes to the establishment of a hypercoagulable state. Here, we describe a case of CVT that developed outside the active phase of CD. A 17-year-old male visited the emergency room because of a sudden onset of right-sided weakness and right-sided hypesthesia. He had been diagnosed with CD 1 year before and was on a maintenance regimen of mesalazine and azathioprine. He did not exhibit any symptoms indicating a CD flare-up (bloody stools, abdominal pain, complications, or weight loss. A brain MRI scan revealed an acute infarction of the left frontal cortex and a cortical subarachnoid hemorrhage. Additionally, a magnetic resonance venography revealed a segmental filling defect in the superior sagittal sinus and also the non-visualizability of some bilateral cortical veins. The characteristics of the present case suggest that the risk of CVT is most likely related to CD per se rather than disease activity associated with CD.

    Breathing vitally serves body homeostasis. The prevalence of upper airway infections is often taken as an indicator of overall health status of a population living at a given time. In the present study we examined the unearthed remains of skulls from the XIII-XV century inhabitants searching for signs of maxillary sinusitis. Maxillary sinuses of the skulls of 92 individuals were inspected macroscopically and, if necessary, endoscopically. Osseous changes, including the pitting and abnormal spicule formation were present in 69 cases (75.0 %). It was found that, overall, dental infection was a major cause of maxillary sinusitis (18.8 %). Severe bone changes were observed in the adults' skulls, but were also present in the sinus walls of children's skulls. Post-inflammatory changes were manifest as remodeling and damage to the sinus walls. The results indicate that both children and adults of the Middle Ages suffered from chronic sinusitis. These observations confirm that the climate, environment, and lifestyle of the medieval populations contributed to the morbidity of the upper respiratory tract.

    Full Text Available Ectopic tooth eruption in a non-dental area is a rare entity, and is most common in oral cavity. There have been a few case reports of teeth erupting in mandibular condyle, chin, palate, coronoid process, and maxillary sinus. Ectopic tooth in the maxillary sinus are found incidentally on routine radiological examination, same time they can be symptomatic and associated with pathologies usually dentigerous cyst or odontogenic keratocyst. Facial pain, purulent rhinorrhoea, epistaxis, headache, swelling, and epiphora-related naso-lacrimal duct obstruction can also be seen. By Caldwell-Luc procedure the ectopic teeth within the maxillary sinus are often removed. In this study, a case of ectopic maxillary third molar tooth on right maxillary sinus is presented.

    Full Text Available Purpose. Radiography is important in forensic odontology for the identification of humans. The maxillary sinus is the largest of the paranasal sinuses and first to develop. Sinus radiography has been used for identification of skeletal remains and determination of gender. Hence, the aim and objectives of the present study were to establish a new method for gender determination using maxillary sinus index from lateral cephalometric radiographs and to establish the reliability of maxillary sinus for gender determination. Methods. A total of 50 adult digital lateral cephalometric radiographs (25 males and 25 females were included in the study. The maxillary sinus analysis was performed on these radiographs using the height and width measurement tools of Sidexis XG software. Maxillary sinus index was calculated, discriminant function analysis performed, and discriminant equation derived for determination of gender. Results. The mean maxillary sinus height and width were found to be higher in males, whereas the maxillary sinus index was greater in females. The discriminant function analysis derived in the study was able to differentiate the sex groups with sensitivity of 68% and specificity of 76%. Conclusions. From the results of the present study, it may be concluded that morphometric analysis of maxillary sinus can be used as a reliable tool in gender determination.

    Cerebral venous thrombosis is a relatively uncommon neurologic disorder that is potentially reversible with prompt diagnosis and appropriate medical care. The pathogenesis is multifactorial and the disease may occur at any age. CVT is often associated with nonspecific symptoms. Radiologists play a crucial role in patient care by providing early diagnosis through interpretation of imaging studies. Underdiagnosis or misdiagnosis can increase the risk of severe complications, including hemorrhagic stroke or death. The purpose of this study is to investigate radiological and clinical characteristics of cerebral venous thrombosis (CVT) based on material from 34 patients under care of our hospital. A total of 34 patients were diagnosed with CVT from August 2009 until March 2015. A clinical and radiological database of patients with final diagnosis of CVT was analyzed. Patient group included 22 women and 12 men at a mean age of 48.7 years (ranging from 27 to 77 years). In the study group 8 patients (23.5%) suffered from hemorrhagic infarction, whereas 16 patients (47%) were diagnosed with venous infarction without hemorrhage. Thirty patients (88%) had transverse sinus thrombosis. According to our study, CVT was more prevalent in women. Transverse sinus was the most common location. Among all age groups, the highest prevalence was seen in the fifth decade (n=14). Contrast-enhanced CT and MR venography were the most sensitive imaging modalities

    Full Text Available Introduction: Maxillary sinus can be visualized in both two-dimensional and three-dimensional images. Computed tomography (CT is considered the gold standard method for the examination of maxillary sinus. Cone beam computed tomography (CBCT addresses the limitation of CT and provides many dental advantages. It can provide valuable knowledge about the pathology with limited exposure and low cost compared with other imaging used for diagnostic purposes. Aims and Objectives: The aim of the study is to analyze the prevalence of pathological changes in maxillary sinus of asymptomatic cases using CBCT for diagnostic purposes. Materials and Methods: This retrospective study evaluated 231 patients for incidental maxillary sinus pathologies. Pathological findings were categorized as mucosal thickening, polypoid mucosal thickening, radiopacification, and no pathological findings. Evaluation of pathological findings was done using factors of age and gender. Results: The present study showed 86 cases with maxillary sinus pathology and 145 cases with no pathological findings. Patients with maxillary sinus pathology were mostly diagnosed with mucosal thickening on both sides. In right maxillary sinus, 45 cases (52.3% showed mucosal thickening, and on the left side 36 cases (41.9% were diagnosed with mucosal thickening. Among 86 cases reported, 20 right maxillary sinus (23.3% and 25 left maxillary sinus (29.1% showed no signs of pathology. Conclusion: The incidental maxillary sinus pathologies are highly prevalent in asymptomatic patients. Therefore, oral radiologists should be aware of these incidental findings which will help in early diagnosis and treatment of disease.

    Portal vein thrombosis in cirrhosis is a relatively common complication associated with the presence of an accompanying prothrombotic phenotype of advanced cirrhosis. The consequences of portal vein thrombosis are relevant because it can be associated with impaired hepatic function, might contraindicate hepatic transplantation and could increase morbidity in the surgical procedure. There is controversy concerning the most effective treatment of portal vein thrombosis, which is based on information that is seldom robust and whose primary objective is to achieve a return to vessel patency. Various studies have suggested that starting anticoagulation therapy early is associated with portal vein repatency more frequently than without treatment and has a low rate of complications. There are no proven data on the type of anticoagulant (low-molecular-weight heparins or dicoumarin agents) and the treatment duration. The implementation of TIPS is technically feasible in thrombosis without cavernous transformation and is associated with portal vein recanalization in a significant proportion of cases. Thrombolytic therapy does not appear to present an adequate balance between efficacy and safety; its use is therefore not supported for this indication. The proper definition of treatment for portal vein thrombosis requires properly designed studies to delimit the efficacy and safety of the various alternatives. Copyright © 2014 Elsevier España, S.L.

    2014-02-01

    We reviewed all journal articles relevant to endoscopic medial maxillectomy in patients with recalcitrant chronic maxillary sinusitis in order to present all indications, the underlying pathophysiology and the developed surgical techniques. Despite the high success rate of middle meatal antrostomy, cases with persistent maxillary sinus disease exist and often need a more extended endoscopic procedure for the better control of the disease. Such surgical option uses gravity for better sinus drainage and offers better saline irrigation, local application of medications and follow-up inspection. An endoscopic medial maxillectomy and its modified forms offer a wider surgical field and access to all 'difficult' areas of the maxillary sinus. Patients with previous limited endoscopic sinus surgery or extended open surgery, cystic fibrosis, extensive mucoceles, allergic fungal sinusitis, odontogenic infections, foreign bodies and so on may suffer from recurrent disease requiring an endoscopic medial maxillectomy. Depending on the disease, various modifications of the procedure can be performed preserving the anterior buttress, nasolacrimal duct and inferior turbinate if possible.

    Manual segmentation of computed tomography (CT) datasets was performed for robot-assisted endoscope movement during functional endoscopic sinus surgery (FESS). Segmented 3D models are needed for the robots' workspace definition. A total of 50 preselected CT datasets were each segmented in 150-200 coronal slices with 24 landmarks being set. Three different colors for segmentation represent diverse risk areas. Extension and volumetric measurements were performed. Three-dimensional reconstruction was generated after segmentation. Manual segmentation took 8-10 h for each CT dataset. The mean volumes were: right maxillary sinus 17.4 cm(3), left side 17.9 cm(3), right frontal sinus 4.2 cm(3), left side 4.0 cm(3), total frontal sinuses 7.9 cm(3), sphenoid sinus right side 5.3 cm(3), left side 5.5 cm(3), total sphenoid sinus volume 11.2 cm(3). Our manually segmented 3D-models present the patient's individual anatomy with a special focus on structures in danger according to the diverse colored risk areas. For safe robot assistance, the high-accuracy models represent an average of the population for anatomical variations, extension and volumetric measurements. They can be used as a database for automatic model-based segmentation. None of the segmentation methods so far described provide risk segmentation. The robot's maximum distance to the segmented border can be adjusted according to the differently colored areas.

    Intravascular selective growth of neoplastic B lymphocytes is a characteristic finding of intravascular large B-cell lymphoma (IVLBCL). However, because neoplastic B cells of IVLBCL grow merely in the lumina of capillaries or small vessels, primary IVLBCL of the great vessels is considered exceptional. To our knowledge, only 2 primary B-cell lymphomas in the lumina of the vena cava have been reported. However, there has been no report of primary B-cell lymphoma with intra-aortic growth. We describe a novel manifestation of primary Epstein-Barr virus-positive large B-cell lymphoma mainly affecting the lumina of the aorta and its major branches in a 76-year-old man. He had a long-term fever that was refractory to antibiotics and aortic mural thrombosis with visceral embolization. Because he had no detectable mass suggesting a malignancy, it was difficult to diagnose while he was alive. He died without anticancer treatment, and the confirmed diagnosis was made at autopsy.

    2015-01-01

    Venous thromboembolism (VTE) is a multifactorial and complex disease in which the interaction of genetic factors (estimated at 60%) and environmental factors (e.g., the use of oral contraceptives, pregnancy, immobility and cancer) determine the risk of thrombosis for each individual. In particular, the association between thrombosis and cancer is well established. Approximately 20% of patients with cancer develop a thromboembolic event over the course of the natural history of the tumor process, with thrombosis being the second leading cause of death for these patients. One of the greatest challenges currently facing the field of oncology is the identification of patients at high risk of VTE who can benefit from thromboprophylaxis. Currently, there is a VTE risk prediction model for patients with cancer (the Khorana risk score); however, its ability to identify patients at high risk is very low. It is important to note that this score, which is based on five clinical parameters, ignores the genetic variability associated with VTE risk. In this article, we present the preliminary results of the Oncothromb study, whose objective is to develop an individual VTE risk prediction model for patients with cancer who are treated with outpatient chemotherapy. Our model includes the clinical and genetic data on each patient (Thrombo inCode(®) genetic profile). Only by integrating multiple layers of biological information (clinical, plasmatic and genetic) we could obtain models that provide accurate information as to which patients are at high risk of developing a thromboembolic event associated with cancer so as to take appropriate prophylactic measures.

    Transverse sinus stenosis (TSS) is common among patients with cerebral venous sinus thrombosis. No previous studies have reported on double-track sign detected on axial Gd-enhanced T1WI in TSS. This study aimed to determine the sensitivity and specificity of the double-track sign in the detection of TSS. We retrospectively reviewed medical records of 383 patients with transverse sinus thrombosis (TST) and 30 patients with normal transverse sinus from 5 participating hospitals in china from January 2008 to June 2014. 167 feasible transverse sinuses included in this study were categorized into TSS (n = 76), transverse sinus occlusion (TSO) (n = 52) and transverse sinus normal (TSN) groups (n = 39) according to imaging diagnosis on digital subtraction angiography (DSA) or magnetic resonance venography (MRV). Double-track sign on axial Gd-enhanced T1WI was compared among the three groups. Sensitivity and specificity of double-track sign in detection of TSS were calculated, with final imaging diagnosis of TSS on DSA or MRV as the reference standard. Of 383 patients with TST recruited over a 6.5-year period, 128 patients were enrolled in the study, 255 patients were excluded because of insufficient clinical data, imaging finding and delay time, and 30 matched patients with normal transverse sinus were enrolled in the control group. Therefore, double-track sign assessment was conducted in 167 available transverse sinuses of 158 patients. Of the 76 sinuses in TSS group, 51 had double-track sign. Of the other 91 sinuses in TSO and TSN groups, 3 had a false-positive double-track sign. Thus, double-track sign on axial Gd-enhanced T1WI was 67.1% (95% CI 55.3-77.2) sensitive and 96.7% (95% CI 89.9-99.1) specific for detection of TSS. The double-track sign on axial Gd-enhanced T1WI is highly specific and moderate sensitive for detection of TSS. Nevertheless, it could be a direct sign and might provide an early clue for TSS.

    Full Text Available In this article, we are sharing a case of a 76-year-old woman with known hypertension, atrial fibrillation,diabetes mellitus, coronary artery disease, who is presenting with stomach necrosis and perforation possibly due to celiac artery thrombosis after newly developed abdominal pain and bloody vomiting. In our case, emergency surgery was planned and the patient refused the operation and was lost at 48 hours of clinical follow-up. We aimed to discuss the etiology of celiac artery thrombosis, briefly. We believe that necrosis and perforation of the stomach due to celiac artery thrombosis deserves to be shared because it is a rare and difficult case to manage.

    Full Text Available The triad of extrapulmonary infection, contiguous septic vein thrombosis, and septic pulmonary embolism is a rare complex but associated with significant morbidity and mortality. Septic azygos vein thrombosis is extremely rare and potentially serious since it may also cause pulmonary emboli and sudden death. We report a case of a 32-year-old woman with history of IV drug abuse who presented with epidural abscess and methicillin-resistant S. aureus (MRSA bacteremia. Later she developed signs of septic pulmonary embolism secondary to septic azygos vein thrombosis. With early diagnosis, appropriate antimicrobial therapy, and control of the infectious source, resolution of the illness can be expected for most patients with avoidance of potential complications.

    Dural sinus malformations (DSM) are rare malformations mainly reported after birth. The objectives of this study are to describe their prenatal patterns and to focus on their possible favorable outcome. This multicenter retrospective study reported 13 cases of DSM prenatally diagnosed. The admission criterion was a dural mass posterior to the vermis. In 12 patients, MRI was performed after US. Follow-up in 10 born babies (mean: 8 months) and three neuropathological examinations were available. In all fetuses, DSM presented as a well-delimited round mass involving the torcular. The follow-up examinations (n = 10) revealed progressive thrombosis of the DSM marked by a heterogeneous pattern (US and MRI) with concentric rings. The volume of the mass decreased, with complete regression in seven patients (five before and two after birth). One child died at the age of 5 months in the context of major hydrocephalus and another developed atrophy of the frontal lobes. The eight other babies were doing well (5 days to 3 years) without any treatment (n = 6) or following treatment for hydrocephalus (n = 2). Prenatal DSM may have a typical MR pattern, and the prognosis might not be as bad as has previously been reported. In the absence of criterion to predict the hydrovenous cerebral imbalance, it is mandatory to check the parenchyma and the ventricles during the pregnancy. (orig.)

    Partial segmental thrombosis of the corpus cavernosum is an unusual clinical condition of unknown origin that mainly affects young males, whose characteristic presentation is the appearance of unexplained perineal pain associated with a palpable perineal mass. This entity consists of thrombosis in the perineal portion of the corpus cavernosum, usually unilateral and it is associated with underlying malignant pathologies and predisposing factors such as microtrauma. After the adequate adherence to conservative treatment, the appearance of complications such as erectile dysfunction is very uncommon. Copyright © 2018 SERAM. Publicado por Elsevier España, S.L.U.

    The silent sinus syndrome (SSS) is a rare clinical entity characterized by painless spontaneous enophthalmos, hypoglobus, and facial deformities secondary to chronic maxillary sinus atelectasis. The aim of this study was to present an SSS diagnostic feature and evaluate the relationship between nasal septum deviation and maxillary sinus volume. A retrospective chart review of the clinical characteristics of 20 patients diagnosed with SSS between January 2013 and July 2014 were analyzed by the Department of Otorhinolaryngology of University Hospital Complex of Santiago de Compostela. 14 patients were females and six males. The mean age was 43 years (range 28-67 years). The right maxillary sinus was involved in 12 patients and the left maxillary sinus in eight patients. There was no statistical difference between gender and the presence of SSS. Maxillary sinus sizes were significantly smaller on the same side as the deviation (p craneo-caudal photographs. The present study demonstrates that, in adult patients, SSS generally presents a septal deviation to the affected maxillary sinus. We recommend performing a paranasal sinus CT scan when the patient has a deviated nasal septum, retraction of the malar eminence (evidenced from the viewpoint cranio-caudal facial) and hypoglobus. FESS performing postero-anterior uncinectomy and enlargement of the maxillary ostium is recommended to restore sinus pressure and prevent progression of the enophthalmos, hypoglobus and facial deformities.

    Between 1969 and 1985, 73 patients with maxillary sinus cancers underwent surgical excision and postoperative radiotherapy. The clinical stage distribution by the AJC system was 3T 1 , 16T 2 , 32T 3 and 22 T 4 . Six patients had palpable lymphadenopathy at diagnosis. Surgery for the primary tumor consisted of partial or radical maxillectomy, and if disease stage indicated it, ipsilateral orbital exenteration. This was followed by radiation treatment delivered through a wedge-pair or three-field technique. All but 3 patients received 50-60 Gy in 2 Gy fractions to an isodose line defining the target volume. Elective neck irradiation (ENI) was nor routinely given. Clinically involved nodes were treated with definitive radiotherapy (5 patients) or combined treatment (1 patient). Forty-five patients had no evidence of disease at the last follow-up. The 5-year relapse-free survival for the whole group was 51 percent. The overall local control rate was 78 percent, Patients with larger tumors, particularly if they also had histological signs of nerve invasion, had a higher recurrence rate than others. The overall nodal recurrence rate without ENI was 38 percent for squamous and undifferen-tiated carcinoma, and only 5 for adenoid cystic carcinomas. Therefore, the current recommendation is to deliver elective nodal irradiation routinely to patients with squamous or undifferentiated carcinoma, except for those who have T 1 lesions. Treatment complications were vision impairment, brain and bone necrosis, trismus, hearing loss, and pituitary insufficiency. The incidence of major side effects was determined by disease extent and treatment technique. Many technical refinements were introduced in order to limit the dose to normal tissues in an attempt to reduce the complication rate. To what extent such practice influences the outcome will be determined from subsequent analysis. (author). 23 refs.; 2 figs.; 5 tabs

    Computed tomography (CT) is now used extensively for the evaluation of orbital, facial, and intracranial infections. Nine patients are presented to illustrate the importance of detecting underlying and unsuspected sinusitis. Prompt treatment of the sinusitis is essential to minimize the morbidity and mortality associated with complications such as brain abscess, meningitis, orbital cellulitis, and osteomyelitis. A review of the literature documents the persistence of these complications despite the widespread use of antibiotic therapy. Recognition of the underlying sinusitis is now possible with CT if the region of the sinuses is included and bone-window settings are used during the examination of patients with orbital and intracranial infection

    2016-11-01

    Full Text Available Introduction: Wipple disease (WD is a rare chronic disease caused by the bacillus Tropheryma whipplei. Constitutive, rheumatologic, gastrointestinal, cardiac, cerebral, lymphatic, cutaneous, and ophthalmological signs are possible systemic symptoms. However, thrombotic manifestations are rarely described as “stroke-like syndrome” or arterial thrombosis. Diagnosis is based on clinical manifestations and pathological examination. Laboratory findings may include anemia, leukocytosis, and thrombocytosis. Objective: We report a case of venous thrombosis as initial manifestation of WD. Case Report: We describe the case of a 53-year-old male with iliofemoral vein thrombosis followed by intermittent diarrhea, loss of appetite, abdominal distension, and bloating. A mild malnutrition state with a weight loss of 13 kg, pallor (+/4 +, presence of lower-limb edema (+/4 +, and hypertympanic distended abdomen occurred. Laboratory tests on admission revealed anemia, positive inflammatory activity tests, and normal coagulation. Endoscopic examination showed villous edema with white dotted infiltrates in the second duodenal portion and intestinal lymphangiectasia in the terminal ileum. Pathological examination revealed numerous macrophages with positive periodic acid-Schiff inclusions. Venous Doppler ultrasound showed extensive deep thrombosis on the left lower limb and recanalization of the femoral vein in the right lower limb. The patient was treated with ceftriaxone and enoxaparin sodium, which led to an improvement of gastrointestinal and thrombosis symptoms. Comments: Hypercoagulability, endothelial damage, vasculitis, and blood stasis are present in T. whipplei infection, which are associated with the activation of inflammatory mechanisms as well as procoagulant and thromboembolic events. WD should be part of the differential diagnosis of diseases that cause venous thrombosis of unknown origin.

    Durg-eluting stent has been regarded as the milestone in the history of PCI for their efficiency in the prevention of coronary arterial restenosis after percutaneous coronary intervention. But unfortunately intra-stent thrombosis continues to be a serious complication of contemporary DES use. The incidence of drug-eluting stents thrombosis is at least not lower than that of bare metal stents at present. The clinical consequences of stent thrombosis are frequently catastrophic, including death in 40% to 50% of the cases or major myocardial infarction in 60% to 70%. Premature discontinuation of standard antiplatelet therapy is by far the most important predictor of stent thrombosis with DES and other predictors included renal failure, diabetes, bifurcation lesions, multiple lesions or multivessel disease, long stents, female, advanced age, stent underexpansion and residual stenosis etc. The delayed endothelialization may be the underling mechanism of DES thrombosis.

    to determine the positive yield of carotid sinus massage in different patient groups: unexplained syncope, falls, dizziness and controls. observational study. teaching hospital. we studied consecutive patients over the age of 60 years referred to the 'falls clinic' with a history of unexplained syncope, unexplained falls and unexplained dizziness. We also studied asymptomatic control subjects recruited from a general practice register aged 60 years and over. All patients and control subjects underwent a full clinical assessment (comprehensive history and detailed clinical examination including supine and erect blood pressure measurements) and 12-lead electrocardiography. We performed carotid sinus massage in the supine position for 5 seconds separately on both sides followed by repeating the procedure in the upright positions using a motorised tilt table. Heart rate and blood pressure were recorded using a cardiac monitor and digital plethysmography respectively. The test was considered positive if carotid sinus massage produced asystole with more than a 3 second pause (cardioinhibitory type of carotid sinus syndrome), or a fall in systolic blood pressure of more than 50 mmHg in the absence of significant cardioinhibition (vasodepressor type of carotid sinus syndrome) or where there was evidence of both vasodepressor and cardio-inhibition as above (mixed type). we studied 44 asymptomatic control subjects and 221 symptomatic patients (130 with unexplained syncope, 41 with unexplained falls and 50 with unexplained dizziness). In the overall symptomatic patient group, the positive yield (any type of carotid sinus syndrome) was 17.6% (95% CI = 12.7-22.5). The positive yield in men (26.3% (95% CI = 16.4-36.2)) was twice that in women (13.1% (95% CI = 7.6-18.6)) (P = 0.014). Overall any type of carotid sinus syndrome was present in 22.3% (n = 29) of the syncope group, 17.1% (n = 7) in the unexplained fallers group and 6% (n = 3) in the dizziness group. We also found that

    The objectives of the present study were to investigate whether kaempferol affects pro-coagulant proteinase activity, fibrin clot formation, blood clot and thrombin (or collagen/epinephrine)-stimulated platelet activation, thrombosis, and coagulation in ICR (Imprinting Control Region) mice and SD (Sprague-Dawley) rats. Kaempferol significantly inhibited the enzymatic activities of thrombin and FXa by 68 ± 1.6% and 52 ± 2.4%, respectively. Kaempferol also inhibited fibrin polymer formation in turbidity. Microscopic analysis was performed using a fluorescent conjugate. Kaempferol completely attenuated phosphorylation of extracellular signal-regulated kinase (ERK) 1/2, p38, c-Jun N-terminal kinase (JNK) 1/2, and phosphoinositide 3-kinase (PI3K)/PKB (AKT) in thrombin-stimulated platelets and delayed aggregation time (clotting) by 34.6% in an assay of collagen/epinephrine-stimulated platelet activation. Moreover, kaempferol protected against thrombosis development in 3 animal models, including collagen/epinephrine- and thrombin-induced acute thromboembolism models and an FeCl3-induced carotid arterial thrombus model. The ex vivo anticoagulant effect of kaempferol was further confirmed in ICR mice. This study demonstrated that kaempferol may be clinically useful due to its ability to reduce or prevent thrombotic challenge.

    Purpose: The veno-occlusive encephalic disease is a neurologic disorder of difficult clinic diagnostic almost always. This clinic situation presents a high morbi-mortality range without an early and precise diagnostic. With the use of Helical Computed Tomography (HCT) and Angio Magnetic Resonance Image (AMRI) the diagnosis has became more effective in the encephalic venous thrombosis. Methods: Fourteen patients with clinical suspicion on encephalic venous thrombosis using non-invasive techniques as HCT and AMRI were studied. Results: In all these cases we were able to arrive at the exact etiologic diagnostic using these techniques associated to the clinics findings, without needing the use of another invasive method like Angiography. Conclusion: The results were satisfactory for definitive diagnosis, without Angiography. When a patient has a high suspicion of veno-occlusive disease the neuro radiologic examination in the urgency is a very important fact and using HCT and AMRI as the first examinations techniques it is possible to obtain good results without most aggressive techniques.

    This review of thrombophilia and coronary thrombosis takes into account the "classical" thrombophilia commonly found in venous pathology and the conditions under which their research may be useful in certain forms of arterial thrombosis especially coronary thrombosis. In addition to the classical thrombophilia, exceptional thrombophilia are evoked, which are both factors of venous thrombosis but also arterial thrombosis. There are also thrombophilia that are more specific to the arterial system such as - homocystein which is potentially both a thrombosis factor but also an agent of arterial parietal lesion or - serotonin which is a factor of arterial spasm and especially coronary spasm. Finally, under the term thrombophilia, it is possible to include thrombophilic conditions, in particular cancers and inflammatory conditions. Copyright © 2017 Elsevier Masson SAS.

    Full Text Available Summary Introduction: In patients with essential thrombocythemia (ET, the vascular complications contribute to morbidity and mortality. To better predict the occurrence of thrombotic events, an International Prognostic Score for Thrombosis in Essential Thrombocythemia (IPSET-thrombosis has recently been proposed. We present the application of this score and compare its results with the usual classification system. Method: We retrospectively evaluated the characteristics and risk factors for thrombosis of 46 patients with a diagnosis of ET seen in the last 6 years at Faculdade de Medicina do ABC (FMABC. Results: Thrombosis in the arterial territory was more prevalent than in venous sites. We observed that cardiovascular risk factors (hypertension, hypercholesterolemia, diabetes mellitus, and smoking were also risk factors for thrombosis (p<0.001. Age over 60 years and presence of JAK2 V617F mutation were not associated with the occurrence of thrombotic events. No patient classified by IPSET-thrombosis as low risk had a thrombotic event. Furthermore, using the IPSET-thrombosis scale, we identified two patients who had thrombotic events during follow-up and were otherwise classified in the low-risk group of the traditional classification. Leukocytosis at diagnosis was significantly associated with arterial thrombosis (p=0.02, while splenomegaly was associated with venous thrombotic events (p=0.01. Conclusion: Cardiovascular risk factors and leukocytosis were directly associated with arterial thrombosis. IPSET-thrombosis appears to be better than the traditional classification at identifying lower risk patients who do not need specific therapy.

    Purpose: We reported on the clinical approaches of ophthalmology and otorhinolaryngology departments in the treatment of the orbital complications of sinusitis. We also included an in-depth literature review. Methods: We retrospectively reviewed the medical files of 51 patients from January 2008 to January 2014. The records were evaluated for age, gender, type of orbital complications, symptoms, predisposing factors, imaging studies, medical and surgical management, culture results, and follow-up information. SPSS version 15.0 software (Statistical Analysis, The Statistical Package for Social Sciences Inc, Chicago, IL) was used for the statistical analysis. Results: Fifty-one patients met the criteria, with available medical records, for the study (29 male, 22 female). Thirty-two (62.7%) were diagnosed with preseptal cellulitis and 19 (37.3%) with postseptal cellulitis. After a detailed evaluation, 15 were diagnosed with a subperiosteal abscess (SPA), and 4 were diagnosed with orbital cellulitis. The age and gender was similar for the two groups. Five patients with medial SPA were treated with endoscopic sinus surgery, one patient with inferior SPA was treated with external surgery, and six patients with other localizations were treated with a combination of endoscopic sinus surgery and external surgery. All patients presented with periorbital erythema and edema. The length of hospitalization and duration of symptoms were similar in both groups. Visual acuity was between 1/10 to 10/10 (mean 7/10) and statistically significant for preseptal and postseptal cellulitis groups (p<0.001). All patients received intravenous antibiotics upon the first day of admission. Conclusion: Orbital complications of acute sinusitis required intensive follow-up and a multidisciplinary approach. A contrast-enhanced paranasal sinus computerized tomography (CT) scan can detect the extent of the infection. An initial trial of intravenosus (IV) antibiotics may be appropriate when close

    Chondrosarcomas are malignant tumors of the cartilage that rarely involve the sinonasal region. Here, we describe a case of histologically verified naso-sinus chondrosarcoma in a 40-year-old female presenting with nasal stuffiness and anosmia. The tumor presented on computed tomography (CT) as an expanding soft tissue mass with bone destruction and pressure erosion. The magnetic resonance images (MRI) of the tumor demonstrated high signals on T2-weighted images with nodular and papillary enhancement along the periphery on T1-weighted images with contrast enhancement. The presence of these typical imaging features should be very helpful in diagnosing chondrosarcoma involving the sinonasal region

    Thrombosis of a large vein can be demonstrated by CT. The thrombosed vein has a hyperdense lumen, with a somewhat increased diameter which does not opacify after intravenous contrast injection, but which shows a narrow hyperdense margin. Collateral vesels in the pelvic or paravertebral plexus and dilated veins in the abdominal skin are indirect evidence of ileo-caval thrombosis. CT can also demonstrate the cranial extent of a caval thrombosis. Venous thrombosis demonstrated by CT is an important additional finding in the pre-operative examination of the abdomen. (orig.) [de

    The results in the early diagnosis of various surgical patients with a high rate of deep venous thrombosis, using the /sup 125/I Fibrinogen Test are presented. A 22 percent incidence of thrombosis was found, and certain limitations have been noticed which make the test only ideal for the venous system distal to the inguinal area and in legs without recent surgical wounds. The real value of the test, as the earliest method for detecting silent venous thrombosis of the legs is emphasized.

    In concluding surgery of the paranasal sinuses (anterior and posterior) and the sphenoidal sinus, caution is demanded because intraorbital complications may develop in the skull. It is well-known that there is substantial variation in the form of the internal wall of the orbit, and the anterior and posterior walls of the sphenoidal sinus. In the present study, we measured the size of the structure around the paranasal sinus on patient CTscans to be used in surgery on the paranasal sinuses. A total of 387 people (184 males and 203 females) with no destructive bone lesions who visited the Juntendo University Hospital between 1999 and June 2002 were investigated. A plane was selected 14 mm above a line drawn between the medial angle and the external acoustic orifice on CTscans performed using axial projection. This framework was used to conduct the measurements. We employed this method because we consider it ideal for rendering the ethmoidal sinuses, the internal wall of the orbit, medial rectus muscle, optic nerve, and the anterior and posterior walls of the sphenoidal sinus most clearly visible. We measured the length between these anatomically important regions. We measured 1) the length of a line drawn between the opening of the nose and the line drawn between the right and left optic canals, 2) the length between the nasal opening and the posterior wall of the sphenoidal sinus, on the same horizontal line drawn between the posterior end of the eyeball and the nasal septum, 3) the length of a line from the site where the optic nerve adheres to the nasal septum, 4) the length between the lateral wall of the ethmoidal sinus, 5) the length between the nasal septum and the medial side of the medial rectus muscle, 6) the length between the medial side of the medial rectus muscle and the medial side of the optic nerve. The measurements were performed on both sides. We analyzed the above results statistically according to gender and age. The results of the analysis

    A 2-year-old Quarter Horse gelding was examined for torticollis, facial protuberances over the frontal and maxillary sinuses, and persistent nasal discharge unresponsive to antibiotics. Radiograph revealed an osseous mass in the right paranasal sinuses. Histologic examination of the biopsied mass led to a diagnosis of osteoma. The mass was removed surgically in sections from the right frontal and maxillary sinuses through separate bone flaps, and sinuses were irrigated with saline solution for 8 days after surgery. Two weeks after surgery, radiography revealed small osseous opacities in the right paranasal sinuses. These opacities remained unchanged in radiographs obtained up to 23 months after surgery

    Full Text Available Silent sinus syndrome is an acquired condition in which there is a gradual collapse of the orbital floor and inward retraction of the maxillary sinus (atelectasis of the maxillary sinus. This in turn may cause associated ocular occurrences of enophthalmos and hypotropia. This is a report of an 8 year-old boy with silent sinus syndrome and associated ocular motility disorders. The association between silent sinus syndrome and ocular motility disturbance has been recently described in the literature. However, this is an infrequent association, mainly in childhood.

    A lateral approach for sinus elevation using plasma rich in growth factors (PRGF) technology is described. The long-term survival of dental implants installed following a two-stage procedure after sinus elevation using this procedure is reported, using implant loss as the outcome variable. A retrospective cohort study design was used. Eighteen patients received 43 implants (BTI implants, Biotechnology Institute, Vitoria, Spain) with sinus floor elevation. All patients presented a residual bone height of class D (1-3 mm). Implants were installed using a low-speed drilling procedure (50 rpm) without irrigation. Finally, the histological and histomorphometric evaluation of eight samples from PRGF grafted sinus involved in the study was carried out 5-6 months posttreatment. The overall survival rate of dental implants was 100%. The mean follow-up period for all implants was 33 +/- 7 months ranging from 24 to 44 months. In addition, the histomorphometrical evaluation of the samples evidenced a 25.24 +/- 4.62% of vital newly formed bone, 50.31 +/- 15.56% of soft connective tissue, and the remaining 24.46 +/- 12.79% of bovine anorganic bone. Based on these results, this new approach for sinus elevation and implant installation using PRGF technology can be considered safe, simple, effective, and predictable.

    Full Text Available OBJECTIVE: To report the uncommon association between neurofibromatosis type 1 (NF1 and unroofed coronary sinus. CASE DESCRIPTION: Girl with four years and six months old who was hospitalized for heart surgery. The cardiac problem was discovered at four months of life. On physical examination, the patient presented several café-au-lait spots in the trunk and the limbs and freckling of the axillary and groin regions. Her father had similar skin findings, suggesting the NF1 diagnosis. The cardiac evaluation by echocardiography disclosed an atrial septal defect of unroofed coronary sinus type. This cardiac finding was confirmed at surgery. The procedure consisted of the atrial septal defect repair with autologous pericardium. COMMENTS: NF1 is a common autosomal dominant disorder caused by mutations in the NF1 gene. Among the NF1 findings, congenital heart defects are considered unusual. In the literature review, there was no association between NF1 and unroofed coronary sinus, which is a rare cardiac malformation, characterized by a communication between the coronary sinus and the left atrium, resultant from the partial or total absence of the coronary sinus roof. It represents less than 1% of atrial septal defect cases. More reports are important to determine if this association is real or merely casual, since NF1 is a common condition.

A cutaneous sinus tract of odontogenic origin is a pathway through the alveolar bone that typically begins at the apex of an infected tooth or of an infected portion of the dental alveolus and empties infected material (pus through the skin. Where as the more common finding of an oral fistula is a pathway from the apical periodontal area of a tooth to the surface of the oral mucous membrane, permitting the discharge of suppurative material. Diagnosis, etiology and treatment are discussed with reference to patient history, clinical examinations, imaging, and treatment perspectives.Keywords: dental abscess, fistula, cutaneous sinus tract, odotogenic infection

    1991-01-01

    This paper reports that ventral and dorsal pleural sinuses are frequently better appreciated with advanced modulated beam equalization radiography (AMBER) than with standard chest radiography. The visualization of the sinuses with both techniques was compared and their typical configuration studied. Four hundred patients without known chest disease were evaluated. Two groups of 200 patients were studied with either AMBER or standard chest radiography. Visualization was evaluated by three radiologists using a four-point scale. The shape of the sinus was traced if sufficiently visible. A significantly larger segment of the respective sinuses was seen with the AMBER technique. The dorsal sinus was significantly easier to trace than the ventral. Various sinus configurations were noted. AMBER improves the visibility of the pleural sinuses. Knowledge of their normal configuration is the precondition for correctly diagnosing lesions hitherto frequently overlooked

    Thromboembolic events are relatively uncommon in childhood. It involves mainly children under one year of age and adolescents, with an incidence is 5.1/10000 live births. Authors present a course of disease of seven cases with neonatal thromboembolic events (2.5/admissions), diagnosed and treated at the Neonatal Division of Department of Pediatrics. In three of seven cases thrombosis proved to be of intrauterine origin. In each of the latter cases, inherited thrombophilia of the mothers was detected. Additional risk factors including infection could be revealed only in one case. Using in vivo and post mortem DNA analysis, mother-like-thrombophilia could not be confirmed in any of the newborns. Based on their experiences, authors suppose that undetected predisposing factors added to maternal thrombophilia can be considered as etiological factor. Authors suggest the intensive follow-up of pregnant women with thrombophilia and also their fetuses.

    Full Text Available Nephrotic syndrome in infancy and childhood is known to be associated with a hypercoagulable state and thromboembolic complications, but cerebral sinovenous thrombosis (CST is a very rare and serious one, with only a few isolated reports in the literature. A case is presented of a 9-year-old boy with nephrotic syndrome that acutely developed signs and symptoms of intracranial hypertension syndrome. CST was diagnosed on cranial CT and MRI and he gradually recovered after treatment with anticoagulants. The diagnosis of CST should be considered in any patient with nephrotic syndrome who develops neurologic symptoms. The discussion of this case, coupled with a review of the literature, emphasizes that early diagnosis is essential for institution of anticoagulation therapy and a successful outcome. This report also illustrates the difficulties that may be encountered in managing such a patient.

    Full Text Available Invasive fungal sinusitis is an infection of the paranasal sinuses that should be diagnosed early due to its high mortality and morbidity rates. Mucormycosis and aspergillus are the two most important agents of invasive fungal sinusitis. Although usually seen in patients who are immunocompromised, they are rarely seen in immunocompetent patients. In this article, we present three patients with ophthalmoplegia; one patient with hematologic malignancy, and two patients with uncontrolled diabetes. By presenting these three patients with invasive fungal sinusitis, we aimed to emphasize the possible role of fungal sinusitis in the development of ophthalmoplegia in patients with diabetes or immunosuppression due to any reason, and the importance of early treatment

    Full Text Available Background: Oroantral communication (OAC is one of the possible complications after extraction of the upper teeth. If not identified and treated properly, a large OAC may develop into oroantral fistula (OAF which means that there is a permanent epithelium-lined communication between antrum and oral cavity. Such fistulas may cause ingress of microorganism from oral cavity into the antrum leading to maxillary sinusitis. Oroantral fistula usually persists if the infection in the maxillary antrum is not eliminated. Therefore, treatment of oroantral fistula should include management of maxillary sinusitis in which surgical closure of oroantral fistula should be done only when the sinusitis has been cured. Purpose: This case report emphasizes on the importance of proper management of maxillary sinusitis in the healing of oroantral fistula. Case: A case of an oroantral fistula following removal of upper left third molar is presented. As the maxillary sinusitis was not identified pre-operatively, two surgical procedures to close the fistula had ended up in dehiscence. Case management: The diagnosis of maxillary sinusitis was finally made and the sinusitis subsequently treated with combination of trans-alveolar sinus wash out, insertion of an acrylic splint, and two series of nasal and sinus physiotherapy procedures. The size of the defect decreased gradually during the treatment of the sinusitis and finally closed up without any further surgical intervention. Conclusion: This case report points out that it is important to detect intraoperatively an antral perforation after any surgery of the maxillary teeth and to close any oroantral communication as early as possible and that it is important to treat properly any pre-existing maxillary sinusitis before any surgical method is done to close the fistula.

    We report a rare case of adenocarcinoma of the sphenoid sinus manifesting as extended skull base tumor. The patient included in the study was a 42-year old woman presenting with unilateral right symptomatology consisting of nasal obstruction, diplopia and hemifacial neuralgias. Clinical examination showed paralysis of the cranial nerve pairs V and VI. Brain scanner showed voluminous heterogeneous sphenoid and clival mass reaching the right cavernous sinus, with a peripheral tissue component at the level of the sphenoid sinus. Biopsy was performed under general anesthesia, through endonasal sphenoidotomy approach. Histological examination showed non-intestinal adenocarcinoma. The patient died due to impaired general condition occurred during examinations. Skull base adenocarcinomas mainly occur in the ethmoid bone. Sphenoid origin is exceptional. Radiological appearance is not specific and suggests malignancy. Diagnosis should be suspected in patients with aggressive tumor, even when it occurs in the midline skull base.

    The East African Early Miocene apes, or proconsulids, have often been considered to be among the earliest members of the Hominoidea, as defined by the divergence of the Cercopithecoidea, but this hypothesis is only weakly supported by available fossil evidence. The ethmofrontal sinus is one of a few morphological features that may link proconsulids with later hominoids. Here we present direct evidence of an ethmofrontal sinus in an early Oligocene stem catarrhine, Aegyptopithecus zeuxis. The presence of this sinus in Aegyptopithecus suggests that its presence in proconsulids is most likely to be a retained primitive condition. The morphological evidence bearing on proconsulids' purported hominoid affinities is further weakened by this conclusion, and alternative phylogenetic possibilities, such as the placement of proconsulids as stem catarrhines are considered more likely.

    2014-01-01

    A fungus ball is an extramucosal fungal proliferation that completely fills one or more paranasal sinuses and usually occurs as a unilateral infection. It is mainly caused by Aspergillus spp in an immunocompetent host, but some cases of paranasal fungal balls reportedly have been caused by Mucor spp. A Mucor fungus ball is usually found in the maxillary sinus and/or the sphenoid sinus and may be black in color. Patients with mucormycosis, or a Mucor fungal ball infection, usually present with facial pain or headache. On computed tomography, there are no pathognomonic findings that are conclusive for a diagnosis of mucormycosis. In this article we report a case of mucormycosis in a 56-year-old woman and provide a comprehensive review of the literature on the "Mucor fungus ball." To the best of our knowledge, 5 case reports (8 patients) have been published in which the fungus ball was thought to be caused by Mucor spp.

    Ovarian vein thrombosis is a rare postpartum complication (0.1%). It can be fatal, since it can lead to sepsis, pulmonary thromboembolisms and inferior vena cava or renal vein thrombosis. Computed tomography and magnetic resonance imaging are the techniques of choice for its diagnosis, while the value of ultrasound is limited due to its low sensitivity and specificity. We report the case of a woman who, during puerperium, developed thrombosis of right ovarian vein that presented clinical, ultrasonographic and computed tomographic features of appendicitis. We describe the radiological sings and stress the fact that this diagnosis should be suspected in puerperal women. (Author) 9 refs.

    Sinusitis is one of the most common diagnoses among adults in ambulatory care, accounting for 15% to 21% of all adult outpatient antibiotic prescriptions. However, the role of antibiotics for sinusitis is controversial. To assess the effects of antibiotics in adults with acute maxillary sinusitis by comparing antibiotics with placebo, antibiotics from different classes and the side effects of different treatments. We searched CENTRAL 2013, Issue 2, MEDLINE (1946 to March week 3, 2013), EMBASE (1974 to March 2013), SIGLE (OpenSIGLE, later OpenGrey (accessed 15 January 2013)), reference lists of the identified trials and systematic reviews of placebo-controlled studies. We also searched for ongoing trials via ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP). We imposed no language or publication restrictions. Randomised controlled trials (RCTs) comparing antibiotics with placebo or antibiotics from different classes for acute maxillary sinusitis in adults. We included trials with clinically diagnosed acute sinusitis, confirmed or not by imaging or bacterial culture. Two review authors independently screened search results, extracted data and assessed trial quality. We calculated risk ratios (RRs) for differences between intervention and control groups in whether the treatment failed or not. All measures are presented with 95% confidence intervals (CIs). We conducted the meta-analyses using either the fixed-effect or random-effects model. In meta-analyses of the placebo-controlled studies, we combined data across antibiotic classes. Primary outcomes were clinical failure rates at 7 to 15 days and 16 to 60 days follow-up. We used GRADEpro to assess the quality of the evidence. We included 63 studies in this updated review; nine placebo-controlled studies involving 1915 participants (seven of the studies clearly conducted in primary care settings) and 54 studies comparing different classes of antibiotics (10 different comparisons

    Two prognostic models to predict overall survival and thrombosis-free survival have been proposed: International Prognostic Score for Essential Thrombocythemia (IPSET) and IPSET-Thrombosis, respectively, based on age, leukocytes count, history of previous thrombosis, the presence of cardiovascular risk factors and the JAK2 mutational status. The aim of the present study was to assess the clinical and biological characteristics at diagnosis and during evolution in essential thrombocythemia (ET) patients as well as the factors associated with survival and thrombosis and the usefulness of these new prognostic models. We have evaluated the clinical data and the mutation status of JAK2, MPL and calreticulin of 214 ET patients diagnosed in a single center between 1985 and 2012, classified according to classical risk stratification, IPSET and IPSET-Thrombosis. With a median follow-up of 6.9 years, overall survival was not associated with any variable by multivariate analysis. Thrombotic history and leukocytes>10×10(9)/l were associated with thrombosis-free survival (TFS). In our series, IPSET prognostic systems of survival and thrombosis did not provide more clinically relevant information regarding the classic risk of thrombosis stratification. Thrombotic history and leukocytosis>10×10(9)/l were significantly associated with lower TFS, while the prognostic IPSET-Thrombosis system did not provide more information than classical thrombotic risk assessment.

    2008-01-01

    Full Text Available Abstract Background The diagnosis of deep vein thrombosis of leg is very common in clinical practice. Not infrequently a range of pathologies are diagnosed after excluding a thrombosis, often after a period of anticoagulation. Case presentation This is a report of three patients who presented with a painful swollen leg and were initially treated as a deep vein thrombosis or a baker's cyst, but later diagnosed as a pleomorphic sarcoma, a malignant giant cell tumor of the muscle and a myxoid liposarcoma. A brief review of such similar reports and the relevant literature is presented. Conclusion A painful swollen leg is a common clinical scenario and though rare, tumors must be thought of without any delay, in a duplex negative, low risk deep vein thrombosis situation.

    Paranasal sinuses are some of the most poorly understood features of mammalian cranial anatomy. They are highly variable in presence and form among species, but their function is not well understood. The best-supported explanations for the function of sinuses is that they opportunistically fill mechanically unnecessary space, but that in some cases, sinuses in combination with the configuration of the frontal bone may improve skull performance by increasing skull strength and dissipating stresses more evenly. We used CT technology to investigate patterns in frontal sinus size and shape disparity among three families of carnivores: Canidae, Felidae, and Hyaenidae. We provide some of the first quantitative data on sinus morphology for these three families, and employ a novel method to quantify the relationship between three-dimensional sinus shape and skull shape. As expected, frontal sinus size and shape were more strongly correlated with frontal bone size and shape than with the morphology of the skull as a whole. However, sinus morphology was also related to allometric differences among families that are linked to biomechanical function. Our results support the hypothesis that frontal sinuses most often opportunistically fill space that is mechanically unnecessary, and they can facilitate cranial shape changes that reduce stress during feeding. Moreover, we suggest that the ability to form frontal sinuses allows species to modify skull function without compromising the performance of more functionally constrained regions such as the nasal chamber (heat/water conservation, olfaction), and braincase (housing the brain and sensory structures). © 2014 Wiley Periodicals, Inc.

    Sinus on the chin can be the result of a chronic apical abscess due to pulp necrosis of a mandibular anterior tooth. The tooth is usually asymptomatic, and a dental cause is therefore not apparent to the patient or the unsuspecting clinician. Not infrequently, the patient may seek treatment from a dermatologist or general surgeon instead of a dentist. Excision and repair of the fistula may be carried out with subsequent breakdown because the dental pathology is not removed. This paper reports the presence of median mental sinus of dental origin in twins. One case healed following root canal therapy while the other required both root canal therapy and surgery to eliminate the infection.

    Tuberous sclerosis complex (TSC) is a genetic neurocutaneous disorder that commonly affects the CNS. The most commonly associated brain tumors include cortical tubers, subependymal nodules, and subependymal giant cell astrocytomas (SEGAs). The authors report an unusual case of recurrent meningitis due to a tuber-containing encephalocele via the posterior wall of the frontal sinus. An 11-year-old girl presented with a history of TSC and previous SEGA resection via interhemispheric approach. She presented twice within 4 months with classic bacterial meningitis. Cerebrospinal fluid cultures revealed Streptococcus pneumoniae. Computed tomography and MR imaging of the brain showed a right frontal sinus encephalocele via a posterior frontal sinus wall defect. Both episodes of meningitis were treated successfully with standard regimens of intravenous antibiotics. The neurosurgical service was consulted to discuss surgical options. Via a bicoronal incision, a right basal frontal craniotomy was performed. A large frontal encephalocele was encountered in the frontal sinus. The encephalocele was herniating through a bony defect of the posterior sinus wall. The encephalocele was ligated and resected followed by removing frontal sinus mucosa and complete cranialization of frontal sinus. Repair of the sinus floor was conducted with fat and pericranial grafts followed by CSF diversion via lumbar drain. Histopathology of the resected encephalocele showed a TSC tuber covered with respiratory (frontal sinus) mucosa. Tuber cells were diffusely positive for GFAP. The patient underwent follow-up for 2 years without evidence of recurrent meningitis or CSF rhinorrhea. This report demonstrates that frontal tubers of TSC can protrude into the frontal sinus as acquired encephaloceles and present with recurrent meningitis. To the authors' knowledge, recurrent meningitis is not known to coincide with TSC. Careful clinical and radiographic follow-up for frontal tubers in patients with TSC is

  18. Chronic Maxillary Sinusitis Associated with an Unusual Foreign Body: A Case Report

    Full Text Available Foreign bodies in maxillary sinuses are unusual clinical conditions, and they can cause chronic sinusitis by mucosal irritation. Most cases of foreign bodies in maxillary sinus are related to iatrogenic dental manipulation and only a few cases with non-dental origin are reported. Oroantral fistulas secondary to dental procedures are the most common way of insertion. Treatment is surgical removal of the foreign body either endoscopically or with a combined approach, with Caldwell-Luc procedure if endoscopic approach is inadequate for visualisation. In this case, we present a 24-year-old male patient with unilateral chronic maxillary sinusitis due to a wooden toothpick in left maxillary sinus. The patient had a history of upper second premolar tooth extraction. CT scan revealed sinus opacification with presence of a foreign body in left maxillary sinus extending from the floor of the sinus to the orbital base. The foreign body, a wooden toothpick, was removed with Caldwell-Luc procedure since it was impossible to remove the toothpick endoscopically. There was no obvious oroantral fistula in the time of surgery, but the position of the toothpick made us to think that it was inserted through a previously healed fistula, willingly or accidentally.

    To investigate aerob-anaerob microorganisms growth in maxillary and ethmoid sinuses by evaluating aspiration materials from patients with chronic sinusitis. The study was performed prospectively, and there were 31 patients (23 men, 8 women; mean age, 31.4+/-14.15, between 18-65 years) who had endoscopic sinus surgery because of chronic sinusitis. During the operation, when the maxillary sinus ostium and ethmoid sinus were opened, readily aspirated materials from sinuses were evaluated regarding aerob and anaerob bacteria. Nose and throat swap samples were collected preoperatively to determine the upper respiratory tract flora and also to understand the relationship between the flora and the microorganisms aspirated from sinuses. Total aerob bacteria count, which was isolated from preoperative nasal swab cultures, was 36, and aerob-anaerob bacteria count that included cultures taken from maxillary and ethmoid sinuses during the functional endoscopic sinus surgery was 42. For each 2 samples, the most common isolated aerob bacteria were coagulase (-) staphylococci. Microorganisms were isolated in 87.0% of 27 patients, in which cultures taken from maxillary and ethmoid sinuses during the functional endoscopic sinus surgery were included. It is determined that the isolated aerob bacteria rate was 90.4%, and the isolated anaerob bacteria rate was 14.2%. All of the 6 samples in which anaerob bacteria isolated were all maxillary sinus aspiration materials. Microorganisms that isolated from the nose and the sinuses were similar with the rate of 25.8%, and microorganisms that isolated from the throat cultures and sinuses were similar with the rate of 22.5%. This study reveals the aerob and anaerob microbiology of the maxillary and ethmoid sinuses so the treatment of chronic sinusitis will be easier.

    Continuous isometric microfocal X-ray computed tomography (CT) scans were acquired from an AKR/J mouse, Brown-Norway rat, and Hartley guinea pig. The anatomy and volume of the paranasal sinus cavities were defined from 2-dimensional (2-D) and 3-dimensional (3-D) CT images. Realistic 3-D images were reconstructed and used to determine the anterior maxillary, posterior maxillary, and ethmoid sinus cavity airspace volumes (mouse: 0.6, 0.7, and 0.7 mm3, rat: 8.6, 7.7, and 7.0 mm3, guinea pig: 63.5, 46.6 mm3, and no ethmoid cavity, respectively). The mouse paranasal sinus cavities are similar to the corresponding rat cavities, with a reduction in size, while the corresponding maxillary sinus cavities in the guinea pig are different in size, location, and architecture. Also, the ethmoid sinus cavity is connected by a common drainage pathway to the posterior maxillary sinus in mouse and rat while a similar ethmoid sinus was not present in the guinea pig. We conclude that paranasal sinus cavity airspace opacity (2-D) or volume (3-D) determined by micro-CT scanning may be used to conduct longitudinal studies on the patency of the maxillary sinus cavities of rodents. This represents a potentially useful endpoint for developing and testing drugs in a small animal model of sinusitis. PMID:19794893

    Introduction: Ectopic sphenoid sinus pituitary adenoma is a rare tumour originating from embryologic remnants of Rathke's pouch. Although it is considered a clinically benign neoplasm, necrosis is encountered in 25% of cases and it can invade adjacent bone structures. Aims: To establish clinical, radiological and histopathological features of ectopic sphenoid sinus pituitary adenoma. Material and methods: Analysis of three cases: two females and one man, aged 61-70. Results: One patient presented with a unilateral hearing loss, the other two with headache and vertigo. They all suffered from type 2 diabetes mellitus. Neurological examination revealed no abnormality. Radiological imaging showed a sphenoid sinus space-occupying soft-tissue lesion with bone erosion in 2 cases and empty sella in 2 patients whereas one had a normal pituitary gland. All were operated on via the transnasal approach. Total resection was achieved in one patient and subtotal in two; in two cases we observed intact sellar dura and in one intact sellar floor. Histopathology showed immunoreactivity for synaptophysin in all cases and cytokeratin in two. The Ki-67 index was less than 2%. Immunohistochemical staining demonstrated growth hormone cells in all cases whereas prolactin and adrenocorticotropin in two. The patients were discharged home in good condition with no neurological deficits. Conclusions: Ectopic sphenoid sinus pituitary adenoma should always be considered in differential diagnosis of sphenoid sinus lesion in the elderly, especially in coexistence with empty sella or type 2 diabetes mellitus. Since ectopic sphenoid sinus pituitary adenoma is a benign lesion, surgical removal is an effective treatment. .

    Deep vein thrombosis and common complications, including pulmonary embolism and post-thrombotic syndrome, represent a major source of morbidity and mortality worldwide. Experimental models of venous thrombosis have provided considerable insight into the cellular and molecular mechanisms that regulate thrombus formation and subsequent resolution. Here, we critically appraise the ex vivo and in vivo techniques used to assess venous thrombosis in these models. Particular attention is paid to imaging modalities, including magnetic resonance imaging, micro-computed tomography, and high-frequency ultrasound that facilitate longitudinal assessment of thrombus size and composition. © 2015 American Heart Association, Inc.

  9. Coronal CT of the paranasal sinuses before and after functional endoscotic sinus surgery

    Mantoni, M.; Larsen, P.; Hansen, H.; Tos, M.; Berner, B.; Oerntoft, S.

    1996-01-01

    Coronal CT of the paranasal sinuses and the ostiomeatal complex (OMC) was performed before and 12 months after bilateral functional endoscopic sinus surgery (FESS) in 30 patients with sinusitis and 12 patients with nasal polyposis. The extent of sinus mucosal thickening was graded, and the patency of the OMC was evaluated. After FESS, the percentage of open OMCs had increased from 42% to 83% in the sinusitis group, and from 8% to 45% in the polyposis group. There was only a small improvement in mucosal score in sinuses with opened OMC, so that the overall extent of sinus opacification before and after FESS was almost the same. Despite this, 91% of the patients reported clinical relief of symptoms. Preoperative coronal CT of the paranasal sinuses serves as an anatomical map for the surgeon, but there is no benefit of routine postoperative CT. (orig.)

    Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3–4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving.

  11. Ophthalmic comlications of functional endoscopic sinus surgery

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available Functional endoscopic sinus surgery (FESS is an effective and safe surgical technique, which revolutionized the surgical management of nasal cavity and paranasal sinus diseases. The intimate connection between paranasal sinuses and the orbit places the orbital content at a risk of injury during sinus surgery, especially that of ethmoid sinuses. The orbit, the optic nerve, extraocular muscles and the lacrimal drainage system could be damaged during FESS. The risk of injury correlates to anatomical variations, degree and severity of disease, previous procedure results, and surgical experience. Ophthalmic complications can vary in severity from minor ones, such as localized hematomas, to extremely dangerous, such as optic nerve injury, that could lead to complete blindness. In order to minimize the risk of such complications, it is necessary to consider probable anatomic variations of paranasal sinuses and orbit, which are to be detected by CT scan before surgery.

    Full Text Available Thymic tumors are rare mediastinal tumors that can present with a wide variety of symptoms. They can cause distant manifestations and are frequently associated with paraneoplastic syndromes. In our case, we describe the evolution of a 68-year-old male whose first manifestation was thrombosis of the inferior vena cava and renal veins. Thrombosis of large abdominal veins is rare, especially without being associated with any other comorbidity or risk factors.

    If the appropriate catheterization of the affected vein was not possible because of a narrowed or thrombus-filled venous lumen, successful treatment gets into trouble during catheter directed regional thrombolysis for treatment of deep vein thrombosis. In this situation, intra-arterial thrombolysis can be considered as an alternative treatment, but to the best of our knowledge, only two reports have been described. We present here cases of successful intra-arterial thrombolysis in patients with deep vein thrombosis.

    Although operative techniques in hepatic transplantation have reduced the time and mortality on waiting lists, the rate of vascular complications associated with these techniques has increased. Stenosis or thrombosis of the portal vein is an infrequent complication, and if present, surgical treatment is considered the traditional management. This article describes a case of acute portal vein thrombosis after liver transplantation from a living donor to a child managed by percutaneous techniques

    The aim of this study was to assess the presence of an occipital sinus in both children and adults, and to detail its main associated anatomical characteristics. One hundred of patients' MRI (3D T1 EG) between 0 and 86 years old were studied, in sagittal and axial sections, with the software DxMM. Occipital sinus length, perimeter, and cerebellar falx length measurements were performed with the software's tools. Forty-three percent of patients had an occipital sinus (average perimeter was 3.02 mm, average length was 19.85 mm), and 23.26% of these patients had a cerebellar falx, 30.23% of these patients had one vein or more draining into the occipital sinus. Sixty-two percent of children had an occipital sinus (average perimeter was 2.87 mm, average length was 21.63 mm), and 29.03% of them had a cerebellar falx. Twenty-four percent of adults had an occipital sinus (average perimeter was 3.4mm, average length was 15.28 mm), and 8.33% of them had a cerebellar falx. This work highlights a link between the age and the occipital sinus existence. The perimeter of this sinus seems to be superior for adults, but its length seems to be superior for children. A cerebellar falx with the occipital sinus was found more frequently for children. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  17. Removal of a Dental Implant Displaced into the Maxillary Sinus by Means of the Bone Lid Technique

    Directory of Open Access Journals (Sweden)

    Pietro Fusari

    2013-01-01

    Full Text Available Background. Rehabilitation of edentulous jaws with implant-supported prosthesis has become a common practice among oral surgeons in the last three decades. This therapy presents a very low incidence of complications. One of them is the displacement of dental implants into the maxillary sinus. Dental implants, such as any other foreign body into the maxillary sinus, should be removed in order to prevent sinusitis. Methods. In this paper, we report a case of dental implant migrated in the maxillary sinus and removed by means of the bone lid technique. Results and Conclusion. The migration of dental implants into the maxillary sinus is rarely reported. Migrated implants should be considered for removal in order to prevent possible sinusal diseases. The implant has been removed without any complications, confirming the bone lid technique to be safe and reliable.

    Neonatal thrombosis is a serious event that can cause mortality or severe morbidity. Although catheters are the most common cause of neonatal thrombosis, spontaneous events can also occur. Arterial thrombosis is very rare and accounts for approximately half of all thrombotic events in neonates. Genetic prothrombotic risk factors may affect the occurence of neonatal thrombosis. In this report, a case of left brachial, radial, and ulnar arterial thrombosis associated with methylene-tetrahydrofo...

  19. Bilateral Deep Vein Thrombosis Associated with Inferior Vena Cava Agenesis in a Young Patient Manifesting as Low Back Pain

    Directory of Open Access Journals (Sweden)

    Felipe Langer

    2017-04-01

    Full Text Available Congenital absence of the inferior vena cava is a rare vascular anomaly, and most cases are asymptomatic. Nevertheless, patients with inferior vena cava malformations may have increased risk of deep venous thrombosis. Particularly, cases of bilateral deep venous thrombosis may arise owing to an insufficient collateral venous drainage from the lower limbs. We hereby describe a case of a previously healthy young male patient presenting with bilateral lower limb deep venous thrombosis as the initial clinical manifestation of congenital inferior vena cava agenesis. We conclude that in young patients presenting with deep venous thrombosis, especially when thrombosis occurs spontaneously, bilaterally, or recurrently, inferior vena cava anomalies should be thoroughly investigated and ruled out as appropriate.

    2015-01-01

    Stent thrombosis is an uncommon but serious complication which carries with it significant mortality and morbidity. This review analyzes the entity of stent thrombosis from a historical and clinical perspective, and chronicles the evolution of this condition through the various generations of stent development, from bare metal to first-generation, second-generation, and third-generation drug-eluting stents. It also delineates the specific risk factors associated with stent thrombosis and comprehensively examines the literature related to each of these risks. Finally, it highlights the preventative strategies that can be garnered from the existing data, and concludes that a multifactorial approach is necessary to combat the occurrence of stent thrombosis, with higher risk groups, such as patients with ST segment elevation myocardial infarction, meriting further research.

    Branchial anomalies comprise approximately 20% of pediatric congenital head and neck lesions. This study reviews current literature detailing the diagnosis and management of first, second, third and fourth branchial cysts, sinuses and fistulae. Branchial anomalies remain classified as first, second, third and fourth cysts, sinuses and fistulae. Management varies on the basis of classification. The imaging study of choice remains controversial. Computed tomography fistulography likely best demonstrates the complete course of the tract if a cutaneous opening is present. Treatment of all lesions has historically been by complete surgical excision of the entire tract. Studies of less invasive procedures for several anomalies are promising including sclerotherapy and endoscopic excision of second branchial cysts, and endoscopic cauterization or sclerotherapy at the piriform opening for third and fourth branchial sinuses. An increased risk of complications in children less than 8 years is reported in children undergoing open excision of third and fourth branchial anomalies. Branchial anomalies are common congenital pediatric head and neck lesions but are comprised by several diverse anomalies. Treatment must be tailored depending on which branchial arch is involved and whether a cyst mass or sinus/fistula tract is present.

  4. Comparison of sonography and venography in the diagnosis of lower extremity deep venous thrombosis

    1993-01-01

    In recent years, non-invasive sonographic techniques [real-time ultrasound (US), duplex ultrasonography (DU) and color-coded duplex sonography (CCDS)] have increased in importance for the diagnosis of lower extremity deep venous thrombosis. To ascertain the accuracy and limitations of these techniques prospectively, various studies have been performed to compare sonography with venography. This review deals with basic methodologic considerations when two imaging methds are compared and describes the features of deep venous thrombosis seen on US, DU and CCDS. Reports comparing sonography and phlebography for the diagnosis of deep venous thrombosis are presented and discussed. The advantages and limitations of US, DU and CCDS for the diagnosis of iliac, femoral, popliteal and infrapopliteal venous thrombosis are compared with those of venography, and controversial areas are touched on.

    We present a patient who showed MRI evidence of a giant temporo-sylvian arachnoidal cyst of the left hemisphere and an extreme pneumatization of the sphenoid and frontal sinuses. No sign of mass effect or cerebral atrophy was detected. This patient presented a deficit of memory and control functions, but quality of life was not affected. Surgery was not performed. Arachnoidal cyst and anatomic variants of the sinus region have not a common etiology. This is the first report that describes a giant temporo-sylvian arachnoidal cyst with anatomic variants of the paranasal sinuses. Copyright © 2010 Elsevier B.V. All rights reserved.

  6. Spontaneous Internal Jugular Vein Thrombosis: A Case Report

    Directory of Open Access Journals (Sweden)

    Mustafa Serinken

    2010-12-01

    Full Text Available Internal jugular vein thrombosis (IJVT is an elusive vascular disease that is rarely seen, with potentially lethal complications such as sepsis and pulmonary embolism. Spontaneous IJVT is considered when no apparent predisposing cause of thrombosis is present. A previously healthy, 31-year-old woman presented to the university-based emergency department because of painless swelling in the right anterior side of her neck. Physical examination revealed a painless, soft and immobile mass in the right anterior side of her neck beneath the sternocleidomastoid muscle, without hyperemia or local heat. On ultrasonographic examination, a hyperechogenic mass was visualized around the thoracic entrance of the right internal jugular vein, which was suggestive of a thrombus. The patient was administered intravenous antibiotic and low-molecular-weight heparin followed by oral coumadin as anticoagulant therapy. Her complaints were relieved within 5 days. She was completely well after 6 months. Venous thrombosis generally results from impaired blood flow locally or systemically that leads to activation of coagulation. Primary care physicians should sustain a high index of suspicion in patients who present with undiagnosed swelling in the neck, or other signs and symptoms attributed to IJVT.

  7. Acute Vision Loss Following Endoscopic Sinus Surgery

    Directory of Open Access Journals (Sweden)

    Serena Byrd

    2017-01-01

    Full Text Available A 41-year-old female with a history of uterine cancer and Celiac and Raynaud’s Disease presented to our institution with frequent migraines and nasal congestion. She underwent functional endoscopic sinus surgery (FESS and experienced acute unilateral vision loss postoperatively. Rapid recognition of the etiology and effective treatment are paramount given the permanent and irreversible vision loss that can result. Arterial vasospasm following FESS is rare. Patients with autoimmune diseases have perhaps an increased risk for vasospasm secondary to an increased vasoreactive profile. We present the first documented case of nitroglycerin sublingual therapy to successfully treat ophthalmic artery vasospasm following FESS. Nitroglycerin sublingual therapy is a promising treatment for ophthalmic vasospasm secondary to its ability to cross the blood-ocular barrier, its rapid onset of action, and its ability to promote relaxation of vascular smooth muscle.

  8. Confirmation of T1-Bright Vein of Galen Aneurysm Spontaneous Thrombosis by Subtraction Magnetic Resonance Venography: A Case Report

    Irfan, M.; Lohman, B.; McKinney, A.M. (Dept. of Radiology/Neuroradiology, Univ. of Minnesota, Minneapolis, Minnesota (United States))

    2009-08-15

    Spontaneous thrombosis of a vein of Galen aneurysmal malformation (VOGM) is rare. We describe a 2-month-old patient with a patent VOGM and hydrocephalus, also confirmed patent at 6 months, but with subsequent lack of filling on pre-embolization catheter digital subtraction angiography (DSA) at 9 months' age. Due to the presence of T1- and T2-bright signal, noncontrast T1-weighted images (T1WI), T2-weighted images (T2WI), two-dimensional (2D) time-of-flight (TOF) magnetic resonance venography (MRV), and postcontrast T1WI were ambiguous for patency. However, subtracting the pre- from the postcontrast MRV images confirmed closure compared to subtracted images at 6 months' age. The factors contributing to thrombosis were likely a combination of a disproportionately small straight sinus, ventriculostomy, and contrast medium from DSA.

  9. Cerebral venous thrombosis after spinal anesthesia: case report

    Directory of Open Access Journals (Sweden)

    Flora Margarida Barra Bisinotto

    2017-05-01

    Full Text Available Introduction: Cerebral venous thrombosis (CVT is a rare but serious complication after spinal anesthesia. It is often related to the presence of predisposing factors, such as pregnancy, puerperium, oral contraceptive use, and malignancies. Headache is the most common symptom. We describe a case of a patient who underwent spinal anesthesia and had postoperative headache complicated with CVT. Case report: Male patient, 30 years old, ASA 1, who underwent uneventful arthroscopic knee surgery under spinal anesthesia. Forty-eight hours after the procedure, the patient showed frontal, orthostatic headache that improved when positioned supine. Diagnosis of sinusitis was made in the general emergency room, and he received symptomatic medication. In subsequent days, the headache worsened with holocranial location and with little improvement in the supine position. The patient presented with left hemiplegia followed by tonic–clonic seizures. He underwent magnetic resonance venography; diagnosed with CVT. Analysis of procoagulant factors identified the presence of lupus anticoagulant antibody. The patient received anticonvulsants and anticoagulants and was discharged on the eighth day without sequelae. Discussion: Any patient presenting with postural headache after spinal anesthesia, which intensifies after a plateau, loses its orthostatic characteristic or become too long, should undergo imaging tests to rule out more serious complications, such as CVT. The loss of cerebrospinal fluid leads to dilation and venous stasis that, coupled with the traction caused by the upright position, can lead to CVT in some patients with prothrombotic conditions. Resumo: Introdução: A trombose venosa cerebral (TVC é uma complicação rara, mas grave, após raquianestesia. Está frequentemente relacionada com a presença de fatores predisponentes, como gestação, puerpério, uso de contraceptivos orais e doenças malignas. O sintoma mais frequente é a cefaleia

    Three cases of cerebral sino-venous thrombosis were reported. Repeated CT findings were studied and discussed on account of the treatments for those pathologic conditions. Those of studied cases are; a 22-year-old postpartum woman, a 42-year-old woman with irregular vaginal bleeding, and a 26-year-old man with severe reactive emesis after drinking alcohol. They were treated conservatively. Case 1 died in its acute stage. In the remaining ones, each had an uneventful recovery. CT scan findings of them manifested their exact clinical conditions. These findings were devided into two categories, one was direct signs expressed sino-venous occlusion, the other was indirect signs which appeared as a result of these occlusion. Direct signs cannot always get in every cases with sino-venous occlusion, but as for indirect signs, we can get various changes corresponding to the time taken CT photoes, and they are useful to decide appropriate treatments at that time. Considering suitable treatments for this disease, it is necessary to select most suitable ones according to their pathologic conditions, which may be precisely drawn with CT scans. (J.P.N.)

    The author has observed the orthopantomograms of the maxillary sinus which were taken by special exposure method to study mesiodistal dimension, shape, symmetrical relationship, bony septum of the maxillary sinus and relationship between upper lst molar and the maxillary sinus, that were selected 56 cases of 23 to 27 years old male, who have good systemic conditions and no missing teeth on upper posterior molar in normal occlusion, and obtained following conclusions: 1. Mesiodistal dimensions of the maxillary sinus are shown as follows; The mean of left dimension is 50.94 {+-} 8.34 mm and of right dimension is 49.50 {+-} 9.87 mm. 2. To the shape of the maxillary sinus, V or U shape are 33 cases(29.5%) and W shape are 77 cases (70.5%). 3. In the ralationship between upper lst molar and floor of the maxllary sinus, superimposition are 62 cases (55.36%) a nd approach are 50 cases (44.64%). 4. In the right and left symmetrical relationship of the maxillary sinus, symmetry are 37 cases (66.07%) and asymmetry are 19 cases (33.93%). 5. The bony septums in the maxillary sinuses revealed that presence of bony septums are 29 cases (25.8%) and absence ar e 83 cases (74.11%).

  13. Lemierre syndrome presenting as acute mastoiditis in a 2-year-old girl with congenital dwarfism

    Directory of Open Access Journals (Sweden)

    Jason B. Fischer

    2015-06-01

    Full Text Available Lemierre syndrome is defined by septic thrombophlebitis of the internal jugular vein caused by Fusobacterium. Historically, these infections originate from the oropharynx and typically are seen in older children, adolescents and young adults. More recently, otogenic sources in younger children have been described with increasing frequency. We present a case of a two-year old, who initially developed an otitis media with perforation of the tympanic membrane and went on to develop mastoiditis and non-occlusive thrombosis of the venous sinus and right internal jugular vein. Fusobacterium necrophorum was grown from operative cultures of the mastoid, ensuing computed tomography scan revealed occlusion of the internal jugular vein and the patient was successfully treated with clindamycin, ciprofloxacin and enoxaparin. This case demonstrates the importance of considering Fusobacterium in otogenic infections and the consideration of Lemierre syndrome when F. necrophorum is identified.

    Objective: To investigate the causes of peripheral vascular thrombosis in patients with paraquat poisoning. Methods: The patients with paraquat poisoning who were admitted to our department in recent two years were observed to screen out the patients with large vessel thrombosis. The data on toxic exposure history, clinical features, and treatment were collected to analyze the causes of thrombosis in the patients with paraquat poisoning. Results: Three patients had typical lower limb thrombosis. There was one case of right common femoral vein thrombosis, one case of bilateral calf muscle vein thrombosis, and one case of right calf superficial vein thrombosis and right calf muscle vein thrombosis. Conclusions: After paraquat poisoning, the blood is in a hypercoagulable state and prolonged bed rest may increase the risk of thrombosis.

    Mycotic infection of paranasal sinus could be the etiological factor of chronic sinusitis. The increase in number of fungal sinusitis cases have been reported recently among nonimmunocompromised patient after endodontic treatment of maxillary teeth. Nonspecific clinical signs and incorrect radiologic pictures interpretation as well as loss of therapeutic standards seems to be the cause of false negative diagnosis and difficulties in treatment of fungal sinusitis. Clinical and radiological picture of maxillary sinus aspergillosis was described in this paper. In the period of 2006-2009 in the Department of Maxillo-Facial Surgery 19 patient with fungal maxillary sinusitis was treated. The endodontic treatment of maxillary teeth of the related side was performed previously in 80% examined cases. In 2 cases there were immunocompromised patients with immunosuppressive treatment. In 16 cases patients were referred to our Department due to metallic foreign body of the maxillary sinus. Routine diagnostic radiological imaging was performed in each case: paranasal sinus view--Water's view and panoramic radiograph (orthopantomograph). In 4 cases imaging was extended with computer tomography (CT) visualization. The surgical treatment was performed in each case. The final diagnosis was puted on histopathological examination and fungal culture. In 16 cases of analysed group histopathological examination and fungal culture revealed aspergilosis. In 2 cases fungal culture was negative, but histopathology slices confirm presence of hyphae of Aspergillus. In 1 case the root canal sealer was found in the maxillary sinus. In none case invasive form of aspergillosis was confirmed. In all cases Water's view of paranasal sinuses and ortopantomograph showed partially or totally clouded sinus with well-defined, single or multifocal radiopaque object similar to metallic foreign body. Characteristic finding in CT imaging was well-defined radiodence concretions that have been attributed to

    We present a typical case of acute suppurative thyroiditis (AST), associated with a piriform sinus fistula. We illustrate the case with an ultrasound picture of a hypoechogenic perithyroid mass and a CT scan using intravenous iodine contrast showing a perithyroid hypodense mass with peripheral enhancement, the mass also having intrathyroid involvement. When clinical and radiological findings suggest the presence of AST, it is necessary to rule out the presence of a piriform sinus fistula by means of a radiological study with barium contrast. Piriform sinus fistula is a rare abnormality derived from the branchial arch which is directly related to recurrent episodes of AST; surgical excision is hence, necessary to avoid such episodes

    Only recently management of benign as well as malignant nasal and paranasal sinus tumours by endoscopy, including endoscopic removal, has been introduced. The most important contribution of the endoscope in the management of these tumours is diagnostic, primarily as well as during follow-up. Although, in general, endoscopic sinus surgery has many advantages over classical external surgery, disadvantages are present when tumours are concerned. Some agreement already exists on the role and limitations of endoscopic sinus surgery in benign tumours, but in malignant processes usually more mutilating procedures are needed and only in selected cases might endoscopic removal be used.

  18. Risk Factors for and Management of MPN-Associated Bleeding and Thrombosis.

    2017-10-01

    The Philadelphia chromosome-negative myeloproliferative neoplasms (MPN) are characterized by both thrombotic and bleeding complications. The purpose of this review is to describe the risk factors associated with bleeding and thrombosis in MPN, as well as to review prevention strategies and management of these complications. Well-described risk factors for thrombotic complications include older age and history of prior thrombosis, along with traditional cardiovascular and venous thromboembolic risk factors. More recently, JAK2 V617F mutation has been found to carry an increased risk of thrombotic complications, whereas CALR has a lower risk than JAK2 mutation. Factors associated with an increased risk of bleeding in MPN include a prior history of bleeding, acquired von Willebrand syndrome, and primary myelofibrosis. Recent findings suggest that thrombocytosis carries a higher risk of bleeding than thrombosis in MPN, and aspirin may exacerbate this risk of bleeding, particularly in CALR-mutated ET. Much of the management of MPN focuses on predicting risk of bleeding and thrombosis and initiating prophylaxis to prevent complications in those at high risk of thrombosis. Emerging evidence suggests that sub-populations may have bleeding risk that outweighs thrombotic risk, particularly in setting of antiplatelet therapy. Future work is needed to better characterize this balance. At present, a thorough assessment of the risks of bleeding and thrombosis should be undertaken for each patient, and herein, we review risk factors for and management of these complications.

    Maxillary sinusitis may develop from the extension of periodontal disease. In this case, reconstructed three-dimensional images from multidetector spiral computed tomographs were helpful in evaluating periodontal bony defects and their relationship with the maxillary sinus. A 42-year-old woman in good general health presented with a chronic deep periodontal pocket on the palatal and interproximal aspects of tooth #14. Probing depths of the tooth ranged from 2 to 9 mm, and it exhibited a Class 1 mobility. Radiographs revealed a close relationship between the root apex and the maxillary sinus. The patient's periodontal diagnosis was localized severe chronic periodontitis. Treatment of the tooth consisted of cause-related therapy, surgical exploration, and bone grafting. A very deep circumferential bony defect at the palatal root of tooth #14 was noted during surgery. After the operation, the wound healed without incidence, but 10 days later, a maxillary sinusitis and periapical abscess developed. To control the infection, an evaluation of sinus and alveolus using computed tomographs was performed, systemic antibiotics were prescribed, and endodontic treatment was initiated. Two weeks after surgical treatment, the infection was relieved with the help of antibiotics and endodontic treatment. Bilateral bony communications between the maxillary sinus and periodontal bony defect of maxillary first molars were shown on three-dimensional computed tomographs. The digitally reconstructed images added valuable information for evaluating the periodontal defects. Three-dimensional images from spiral computed tomographs (CT) aided in evaluating and treating the close relationship between maxillary sinus disease and adjacent periodontal defects.

    We aimed to define the classification of frontal sinus pneumatization patterns according to three-dimensional volume measurements. Datasets of 148 sides of 74 dry skulls were generated by the computerized tomography-based volumetry to measure frontal sinus volumes. The cutoff points for frontal sinus hypoplasia and hyperplasia were tested by ROC curve analysis and the validity of the diagnostic points was measured. The overall frequencies were 4.1, 14.2, 37.2 and 44.5 % for frontal sinus aplasia, hypoplasia, medium size and hyperplasia, respectively. The aplasia was bilateral in all three skulls. Hypoplasia was seen 76 % at the right side and hyperplasia was seen 56 % at the left side. The cutoff points for diagnosing frontal sinus hypoplasia and hyperplasia were '1131.25 mm(3)' (95.2 % sensitivity and 100 % specificity) and '3328.50 mm(3)' (88 % sensitivity and 86 % specificity), respectively. The findings provided in the present study, which define frontal sinus pneumatization patterns by CT-based volumetry, proved that two opposite sides of the frontal sinuses are asymmetric and three-dimensional classification should be developed by CT-based volumetry, because two-dimensional evaluations lack depth measurement.
