Combined treatment of a dural arteriovenous malformation of the lateral sinus using transarterial and direct lateral sinus embolisation.

An 80-year-old man presented with a dural arteriovenous malformation (DAVM) involving the left lateral sinus. A carotid angiogram showed the lateral sinus to be occluded proximally and distally, with unusual retrograde venous outflow from the residual sinus to the cortical veins, including a dilated vein of Labbé. Single photon emission computed tomography showed reduced left frontal and temporal cerebral blood flow. We concluded that the risk of bleeding from the DAVM was high and that the patient needed to be treated immediately. However, his age made surgical removal of the DAVM hazardous and we therefore chose to treat him by transarterial and direct lateral sinus embolisation via a burr hole.

Shortcomings of lateral sinus radiograph in the preoperative determination of the extent of endonasal endoscopic sinus surgery.

Lateral sinus radiograph is helpful in determining the distances between certain anatomic landmarks in preparation for endonasal endoscopic sinus surgery. However, some misleading factors limit the usefulness of this radiograph. In this study these distances were measured in 49 patients and compared with measurements obtained from another imaging modality, magnetic resonance imaging, which provides more accurate measurements. Results show a discrepancy in the measurements of distances between some of these landmarks that cannot be explained by the factor of magnification alone on the sinus radiographs. Statistical analysis of the results for women revealed a significant discrepancy between the distances from the nasal spine to the midfovea ethmoidalis, the sphenoethmoid junction, and the posterior sphenoid wall as measured on MR images and those as measured on lateral sinus radiographs (P < .05). For men the same was true for the distances from the nasal spine to the midfovea ethmoidalis and the posterior sphenoid wall (P < .05). It is concluded that there should be reservations in the surgical application of data provided by the lateral sinus radiograph before endoscopic sinus surgery.

[Lateral sinus thrombosis].

Lateral sinus thrombosis has become a rare complication of the ear in the developed world with the widespread use of antibiotics. The classic clinical picture is often modified by previous antibiotic treatment, which difficult diagnosis and treatment. The authors present the case of a seven year old female who, after an acute left otitis media, treated and later complicated with mastoiditis, presented headaches, neck pain, papilledema and binocular diplopy. Etiologic investigation lead to the diagnosis of left lateral sinus thrombosis. Anticoagulation was started with heparin followed by dicumarinics. This treatment was maintained during eight months. At the moment, the child has no symptoms, with no papilledema or repercussions on visual acuity. The diagnosis of lateral sinus thrombosis and the need for a selection of complementary studies is discussed. A protocol treatment, based on data from a review of the literature, is suggested.

A caution regarding the use of low-molecular weight heparin in pediatric otogenic lateral sinus thrombosis.

Lateral sinus thrombosis (LST), a rare complication of otitis media, is managed by antibiotics, surgery and anticoagulation. Traditionally, post-operative anticoagulation has been achieved by intravenous unfractionated heparin followed by oral warfarin. Fractionated, or low-molecular weight heparin derivatives (LMWH) have been introduced recently. There has been minimal literature to date regarding their use for the management of LST. We present use of the LMWH enoxaparin (Lovenox) for otogenic LST in two children, both of whom experienced hemorrhagic complications. On this basis and in the context of a literature review, we urge caution when using LMWH for pediatric otogenic LST.

Magnetic resonance imaging in lateral sinus hypoplasia and thrombosis.

Lateral sinus thrombosis may be difficult to differentiate angiographically from lateral sinus hypoplasia, which mainly affects its proximal transverse portion. Using magnetic resonance imaging, we evaluated six patients who demonstrated poor filling or lack of filling of one or both lateral sinuses at angiography. In each patient, magnetic resonance imaging unambiguously demonstrated either lateral sinus thrombosis or lateral sinus hypoplasia. The latter was characterized by a frank asymmetry in size (surface of section) of the transverse portion of the lateral sinuses on parasagittal images without any abnormal signal in the course of the sinus. Lateral sinus thrombosis was indicated by increased intraluminal signal on all planes and with all pulse sequences. By virtue of its freedom from bone-related artifact, its multiplanar imaging capability, and its sensitivity to both blood flow and thrombus formation, magnetic resonance imaging is an excellent tool for the evaluation of lateral sinus thrombosis or hypoplasia.

The changing face of lateral sinus thrombosis.

Lateral sinus thrombosis is a life threatening complication of middle ear disease, the presentation, diagnosis and management of which has seen many changes in recent times. While the introduction of antibiotics has been associated with a reduction in the incidence and associated morbidity/mortality of this complication, their use has also altered the clinical features of presentation, consequently diagnosis requires a high index of suspicion. Radiological advances, in particular magnetic resonance imaging and magnetic resonance venography, have improved our ability to diagnose this complication pre-operatively, and now are the diagnostic investigations of choice. Intraoperative sigmoid sinus exploration and removal of all necrotic clot are essential steps of surgical management together with appropriate antimicrobial treatment, however the role of anticoagulation therapy remains controversial. We present four recent cases of sigmoid sinus thrombosis and discuss the clinical presentation, investigation and management of this disease.

[Lateral sinus thrombophlebitis].

Lateral sinus thrombophlebitis (LST) is an intracranial complication of otitis media. Its incidence has markedly decreased in the era of antibiotic therapy but mortality is still high. A 13-year-old girl presented with fever, ear discharge and torticollis. On the day of admission LST was diagnosed from the clinical presentation and CT-scan. She was operated immediately and intravenous antibiotics were administered. Despite the rapid intervention, the course was protracted, with recurrent events of septic pulmonary embolism. Despite internal jugular vein ligation, fever continued and anticoagulant therapy was begun. The possibility of LST should be considered in patients with ear discharge and fever. CT-scan enables early diagnosis of LST and MRI has a role in detecting additional intracranial septal foci. Surgical intervention should be early and aggressive. The efficacy of jugular vein ligation is unclear; anticoagulant therapy should be considered.

Management of otogenic lateral sinus thrombosis.

PURPOSE: Lateral sinus thrombosis (LST) is a rare but potentially devastating complication of otitis media. We review the clinical presentation, evaluation, management, operative findings, and outcomes of this serious complication. MATERIAL AND METHODS: A retrospective chart review was performed at a teaching hospital of all patients diagnosed with an otogenic lateral sinus thrombosis between 1992 and 2002. Data on patients with otogenic LST were collected and analyzed. RESULTS: Eleven patients were identified with a diagnosis of lateral sinus thrombosis, and all had a chronic otitis media. The most common presenting symptoms were headache, otalgia, and fever. Radiologic evaluation included computed tomography scan, magnetic resonance imaging, or magnetic resonance venography. All patients had radiographic evidence of LST preoperatively. The thrombosed sinus was on the right side in 6 patients and on the left side in 5 patients. The majority of patients (8 of 11) had a second concomitant intracranial complication. All patients underwent a mastoidectomy. The thrombus was removal in 7 cases, whereas only needle aspiration of the sinus was performed in 4 cases. Gram-negative bacilli and anaerobes were the most common organisms. There were no deaths but sequelae included VI nerve palsy, ataxia, and dead ear. CONCLUSION: LST as a complication of otogenic infections may still pose a serious threat that warrants immediate attention and care. It is frequently associated with other intracranial complications. Contrast-enhanced computed tomography scan and magnetic resonance imaging plays a major role in determining diagnosis and treatment plans. The availability of broad-spectrum antibiotics has improved our management significantly. Conservative surgical intervention including eradication of all perisinus infection and needle aspiration of the sinus seems to be effective.

Lateral sinus thrombosis: a sometimes unexpected diagnosis.

Lateral sinus thrombosis, a frequent complication of ear infections in preantibiotic days, is seldom seen today. When it does occur, it is usually in a patient with a known history of a chronic ear infection. Two patients are described with septic pulmonary emboli from inapparent lateral sinus thrombosis. Lateral sinus thrombosis should be suspected in any patient with chills, fever, neck pain, and septic pulmonary emboli.

Correlation between mastoid pneumatization and position of the lateral sinus.

The distance between the lateral sinus and the external ear canal was measured in 148 patients (150 ears) with completely sclerotic (nonpneumatized) mastoids and in 75 healthy random control subjects (150 ears), with pneumatized mastoids. A highly significant difference (p less than .0001) was found between the two groups, the mean distance (+/- SD) among patients being 7.8 +/- 1.7 mm, while among controls it was 13.5 +/- 2.8 mm. Moreover, a significant positive correlation (p less than .001) was found within the pneumatized control group itself, between the sinus' distance and the degree of mastoid pneumatization. The results of this study may be interpreted by those who espouse environmental theories as denoting that infantile otitis media will determine the position of the lateral sinus. However, those who favor the genetic explanation may maintain that since the position of the sinus is established prenatally and involves organogenetically the shape of the skull, the final position is unlikely to be influenced by postnatal otitis media.

Lateral sinus thrombosis.

The incidence of lateral sinus thrombophlebitis has been significantly reduced since the advent of antibiotics. This entity is rarely encountered in clinical practice, so a high index of suspicion is essential for early diagnosis and appropriate management. Although uncomplicated dural venous thrombosis carries an excellent prognosis with proper treatment, delay in diagnosis and institution of appropriate therapy may lead to serious, or even fatal, consequences. It is hoped that this case report and discussion will serve to increase the awareness of lateral sinus thrombophlebitis as a potential complication of suppurative otitis media.

Combined sagittal and lateral sinus dural fistulae occlusion.

The clinical course of three patients who had combined sagittal and lateral sinus dural fistulae is described. One patient, with impending blindness and a short life span, underwent right lateral sinus thrombosis in one stage. The second patient underwent sagittal and right lateral sinus thrombosis in four stages, and her remaining lateral sinus spontaneously occluded. A small untreated fistula persists in the right lower sigmoid. The third patient underwent sagittal sinus, left lateral sinus, and left parietal sinus thrombosis in six stages. A small untreated far-anterior fistula persists. All "satellite" fistulae have spontaneously disappeared. The small asymptomatic untreated residual fistulae have no demonstrable retrograde venous drainage and, therefore, require no treatment at this time.

Nonseptic lateral sinus thrombosis: the otolaryngologic perspective.

Nonseptic lateral sinus thrombosis (NSLST) differs from septic lateral thrombosis (SLST) in that it is not associated with ear or sinus infection, it usually occurs in the adult population, and it has an ambiguous clinical presentation. The otolaryngologist is often consulted about diagnostic findings associated with lateral sinus thrombosis. We report three cases of NSLST that required otolaryngologic assessment. The patients were women, ages 23 to 31 years. Presenting symptoms were headaches in all three patients; one also had concomitant ear pain. Two patients had negative head computed tomography scans; only magnetic resonance imaging was diagnostic. Treatment of NSLST consists of anticoagulation and elimination of predisposing factors. Familiarity with this condition is fundamental for early diagnosis and initiation of appropriate therapy. We discuss the origins and causes of NSLST, clinical presentation, preferred diagnostic strategy, and treatment alternatives.

Late development of lateral sinus vein thrombosis.

The incidence of lateral sinus vein thrombosis has been reduced by the use of antibiotics, but it is still a major complication of middle ear disease. Patients without active acute or chronic middle ear infection, however, develop this deadly complication. CT scan is helpful in diagnosis, but mostly the final diagnosis is made by surgical exploration. A case of a 23-year-old patient who developed lateral sinus vein thrombosis without an active middle ear disease is presented. The pertinent literature is discussed.

Diagnosis and management of lateral sinus thrombosis.

OBJECTIVES: To define the contemporary management of septic otogenic lateral sinus thrombosis. STUDY DESIGN: Retrospective case series identified through database search of otologic surgical cases managed by a single surgeon in four teaching hospitals over a 6-year period. METHODS: Twelve patients presenting with lateral sinus thrombosis of otogenic cause were the subjects of this study. Patients with incomplete medical records or unknown outcomes were excluded. RESULTS: Lateral sinus thrombosis was the result of chronic otitis media in 50% of cases, with five of these patients having cholesteatoma. In addition, there were seven associated intracranial complications in six patients in this series. All patients underwent medical and surgical treatment. Aggressive and early surgical treatment was tailored to the degree of preoperative and intraoperative findings. The sigmoid sinus was resected in six of the patients with a variable degree of inferior margin proportional to the extent of thrombosis. Thrombectomy alone under vascular control with reestablishment of flow was used to remove the septic thrombus in the other six patients. There were no complications in these patients. CONCLUSION: Early and aggressive surgical intervention of this otogenic complication can potentially minimize mortality, hospital stay, and length of medical treatment.

Management of lateral sinus thrombosis.

OBJECTIVES: Review the clinical signs and symptoms, management, bacteriology and outcomes of patients treated for lateral sinus thrombosis. STUDY DESIGN: A retrospective review of six patients, treated from 1993 through 1998, with an intraoperatively confirmed diagnosis of lateral sinus thrombosis. METHODS: All charts from 1993 through 1998 coded for sinus thrombosis, meningitis, brain abscess, otitic hydrocephalus, subdural abscess, and mastoidectomy were reviewed. Operative reports, radiological examinations, laboratory data, culture data and other pertinent data were reviewed. RESULTS: The presenting symptoms ranged from headache to mental status changes. All patients had a history of chronic ear disease and all had at least one additional intracranial complication. The range of additional intracranial complications included otitic hydrocephalus, epidural abscess, and brain abscess. All of the infections were polymicrobial, with a predominance of anaerobes. There were no mortalities; morbidities included anacusis, acute respiratory distress syndrome, reoperation, seizures, septic cardiomyopathy, transfusion, ventriculoperitoneal shunt and nutritional supplementation. CONCLUSION: In patients with otologic disease, complaints of headache, earache or photophobia should warrant an evaluation. The presence of lateral sinus thrombosis mandates further investigation for additional intracranial complications. Conservative surgical intervention, consisting of removal of all perisinus infection and needle aspiration of the sinus, has been found to be effective. Lateral sinus thrombosis is an uncommon complication of otitis media, with potentially significant morbidities, necessitating a high index of suspicion.
