isolated Lateral Sinus Thrombosis a series of 62 patients
Stroke, 2009Co-Authors: Mariem Damak, Isabelle Crassard, Valerie Wolff, M G BousserAbstract:Background and Purpose— Isolated Lateral Sinus Thrombosis was long considered a complication of middle ear disease. Little attention has been recently paid to this variety of Thrombosis. We therefore reviewed all cases of isolated Lateral Sinus Thrombosis prospectively collected in our center (1997 to 2006). Methods— Among 195 patients with cerebral venous Thrombosis (CVT), we identified 157 patients with Lateral Sinus Thrombosis, including 62 patients with isolated Lateral Sinus Thrombosis. Clinical, etiologic, and prognostic features were compared with those of other 133 CVT cases. Result— Sixty-two patients (32%) had isolated Lateral Sinus Thrombosis. Headaches were present in 95% of patients. The main clinical presentation was isolated headache in 28 patients (45%), whereas 15 (24%) had isolated intracranial hypertension. Nineteen patients (31%) had at least one focal sign (deficit and/or focal seizure). Dysphasia was the most common one (8 patients). Compared with the other 133 CVT cases, presentatio...

isolated Lateral Sinus Thrombosis 43 cases
Stroke, 2000Co-Authors: Isabelle Crassard, Valerie Wolff, Alain Ameri, Valerie Biousse, M G BousserAbstract:P4 Background and Objective: Since the preantibiotic era, where isolated Lateral Sinus Thrombosis (isolated LST) was known as “otitic hydrocephalus”, little attention has been paid to this variety of cerebral venous Thrombosis (CVT). We therefore reviewed all cases of isolated LST prospectively collected in our center over 25 years. Methods: Among 185 patients with CVT examined between 1975 and April 2000, we identified 135 patients with LST and among them 43 patients with isolated LST. Diagnosis was based on conventional angiography and/or magnetic resonance imaging and/or helical cerebral CT venography. Clinical, etiologic and prognostic features were studied and compared with those of the other 142 CVT cases. Results: 43 patients (23%; 28 female, 15 male) had isolated LST: right in 17, left in 25, biLateral in 1. The main clinical symptoms were headache (88%), papilledema (44%), seizures (28%), motor or sensory deficit (19%), multiple cranial nerves palsy (19%), altered consciousness (9%), dysphasia (9%). The single common pattern of presentation was isolated intracranial hypertension in 20 patients (47%). Four patients had isolated headaches (9%) and 19 (44%) had at least one focal sign (deficits and/or partial seizures). Compared with the other 142 CVT cases, presentation with isolated headaches or intracranial hypertension was more frequent (p=0.02) and altered consciousness or partial seizure less common (p=0.01; p=0.004). Numerous causes or predisposing factors were identified among them septic and local causes represented respectively 14% and 19%. The association of both was significantly more frequently found that in other CVT patients (p=0.01). Treatment consisted of anticoagulation in 32 patients (74%). Complete recovery occurred in 37 patients (86%), 5 patients had sequelea (12%) and 1 died of a carcinoma (2%), compared with respectively 71.5%, 24% and 4.5% for the other 142 CVT cases (no significant difference). Conclusion: The isolated LST is a frequent variety of CVT, presenting in a majority of cases with isolated intracranial hypertension or headache. Septic and local causes are more frequent that in other variety of CVT and require specific treatment. Its prognosis is usually good.

Lateral Sinus Thrombosis in children a review
Pediatrics & Therapeutics, 2019Co-Authors: B. ViswanathaAbstract:A retrospective study was undertaken to review the clinical presentation, evaluation, management, and outcome of otogenic Lateral Sinus Thrombosis (LST) in children. All pediatric patients with LST seen in our department between 1999 and 2007 were included; there were 9 cases involving 6 boys and 3 girls whose ages ranged from 8 to 12 years. They had all been treated with antibiotics elsewhere prior to admission, and the duration of symptoms before admission ranged from 5 to 18 days. The most common presenting symptoms were ear discharge, headache, otalgia, and fever. Radiologic evaluation included computed tomography and magnetic resonance imaging. All patients underwent radical mastoidectomy with incision of the Lateral Sinus and removal of its content. There were no deaths. Pseudomonas and Proteus spp were the most commonly identified organisms. Otogenic LST still poses a serious threat that warrants immediate attention and care. It is often associated with other intracranial complications, such as cerebellar abscess. Computed tomography and magnetic resonance imaging play an important role in the management of this disease. Early and aggressive surgical intervention of this otogenic complication can potentially minimize mortality.

otological manifestations of nonseptic Lateral Sinus Thrombosis a review
Indian Journal of Otolaryngology and Head & Neck Surgery, 2016Co-Authors: Maliyappanahalli Siddappa Vijayashree, B. ViswanathaAbstract:Nonseptic Lateral Sinus Thrombosis differs from septic Lateral Sinus Thrombosis in that it is not associated with ear or Sinus infection. Etiologies of these conditions are different and management of these conditions are different. Nonseptic Lateral Sinus Thrombosis requires medical line of management and anticoagulant therapy where as septic Lateral Sinus Thrombosis treatment involves surgical exploration of the mastoid cavity, Sinus decompression, and long-term antibiotic therapy. Mastoid changes are frequently detected on computed tomography or magnetic resonance imaging in cases of nonseptic Lateral Sinus Thrombosis. An otolaryngologic evaluation is usually required to exclude coexisting mastoiditis. An otologist should be familiar with the septic Lateral Sinus Thrombosis and existence of nonseptic variant Lateral Sinus Thrombosis for early recognition and initiation of appropriate treatment.

Nonseptic and Septic Lateral Sinus Thrombosis: A Review
Indian Journal of Otolaryngology and Head & Neck Surgery, 2014Co-Authors: B. Viswanatha, C. N. Thriveni, Khaja NaseeruddinAbstract:Thrombosis of the Lateral Sinus can be classified into nonseptic Lateral Sinus Thrombosis and septic Lateral Sinus Thrombosis. Nonseptic Lateral Sinus Thrombosis differs from septic Lateral Sinus Thrombosis in that it is not associated with ear or Sinus infection. Etiologies of these conditions are different and hence the management of these conditions is different. Nonseptic Lateral Sinus Thrombosis requires medical line of management and anticoagulant therapy, where as septic Lateral Sinus Thrombosis needs surgical treatment along with antibiotics therapy. An otologist should be familiar with the septic Lateral Sinus Thrombosis existence and nonseptic variant Lateral Sinus Thrombosis for early recognition and initiation of appropriate treatment.

Lateral Sinus Thrombosis in otology a review
Mediterranean Journal of Hematology and Infectious Diseases, 2010Co-Authors: B. Viswanatha, Khaja NaseeruddinAbstract:Lateral Sinus Thrombosis (LST) is usually occurs as a complication of middle ear infection .The involvement of Lateral Sinus during the course of ear infection was a well known complication in preantibiotic days . The decrease in the incidence of LST is due to the introduction of broad-spectrum antibiotics, early diagnosis and surgical treatment . Now, it is a rare complication of otitis media and poses a serious threat that warrants immediate medical and surgical treatment. The classical clinical picture is often changed by previous antibiotic therapy. An awareness of this rare potentially devastating condition and its varied presentations is necessary for early diagnosis and treatment. LST can also occur after head injury.

nonseptic Lateral Sinus Thrombosis the role of the otolaryngologist
Ear nose & throat journal, 2009Co-Authors: B. ViswanathaAbstract:Nonseptic Lateral Sinus Thrombosis differs from septic Lateral Sinus Thrombosis in that it is not associated with ear or Sinus infection. Mastoid changes are frequently detected on computed tomography or magnetic resonance imaging in cases of nonseptic Lateral Sinus Thrombosis. An otolaryngologic evaluation is usually required to exclude coexisting mastoiditis.

otogenic Lateral Sinus Thrombosis case series and controversies
International Journal of Pediatric Otorhinolaryngology, 2014Co-Authors: Jamie Lauren Funamura, Alexander T Nguyen, Rodney C DiazAbstract:Abstract Objectives The aim of this study is to (1) report the clinical presentation, treatment, and sequelae in a series of pediatric patients with otogenic Lateral Sinus Thrombosis and (2) to review the most controversial aspects of management of this rare intracranial complication of otitis media. Methods Retrospective chart review of inpatients treated for central venous Thrombosis at a tertiary care facility between 1996 and 2012. Results Five pediatric patients (four male, one female) were identified with otogenic Lateral Sinus Thrombosis. Age at presentation ranged from 13 months to 15 years. All underwent a surgical procedure, ranging from a simple myringotomy with tympanostomy tube placement to tympanomastoidectomy and internal jugular vein ligation or craniotomy. Three were anticoagulated with unfractionated heparin with subsequent transition to low molecular weight heparin of variable duration. One patient developed a non-life-threatening intracranial hemorrhage while on long-term anticoagulation. Follow-up imaging, when available, did not directly correlate complete thrombus resolution with use of anticoagulation or with persistent symptoms. Conclusions Otogenic Lateral Sinus Thrombosis is a rare intracranial complication of otitis media with significantly reduced morbidity and mortality in the modern era of antibiotic treatment, surgical intervention, and anticoagulation therapy. Due to the rarity of this condition today, the recommended extent of surgical intervention and need for routine anticoagulation are unclear, and requires further data to determine definitively.
