The clinical characteristics, implicated pathogens and therapeutic outcomes of culture-proven septic cavernous sinus thrombosis

Septic Cavernous Sinus Thrombosis: Clinical Characteristics, Management, and Outcomes

BACKGROUND

Septic cavernous sinus thrombosis (CST) is a rare condition traditionally associated with high morbidity and mortality. More recent case series report more favorable outcomes, including full functional recovery. A comprehensive assessment of the clinical characteristics and prognostic factors of visual and survival outcomes in septic CST is warranted to contemporize current understanding and help guide management.

METHODS

A multicentered retrospective cohort study was conducted at 2 tertiary care centers using an electronic medical record search of the term, "thrombosis of cavernous venous sinus" between January 1, 2000, and December 31, 2021. Inclusion criteria consisted of active infection and radiographic evidence of associated CST. Demographic and clinical data extracted included age at presentation, sex, infection type and extent, and ophthalmic examination findings at presentation-best-corrected visual acuity (BCVA), presence of relative afferent pupillary defect (RAPD), intraocular pressure (IOP), and extraocular motility (EOM) limitation. Management data collected consisted of type and length of antimicrobial therapy, type and length of anticoagulation administration, and surgical intervention. Primary outcomes assessed were ophthalmic examination findings at final evaluation and same-hospitalization mortality.

RESULTS

A total of 27 patients with imaging-confirmed septic CST were identified at 2 tertiary care centers. At presentation, 2 (8.7%) patients had no light perception (NLP) vision, 8 (29.6%) patients had RAPD, 17 (73.9%) patients had EOM limitation, and 13 (54.2%) had IOP >21 mm Hg. All patients received antimicrobial therapy, with vancomycin being the most common agent. Fifteen patients (55.6%) received anticoagulation, and 21 (81.5%) patients underwent surgical intervention. Same-hospitalization mortality was 3 (11.1%). Among the 21 patients with ophthalmic data at follow-up, 3 (16.7%) had NLP vision, 5 (23.8%) had a persistent RAPD, 7 (31.8%) had persistent EOM limitation, and no patients had IOP elevated above 21 mm Hg. Patients with RAPD at presentation had significantly worse BCVA at final evaluation (logMAR BCVA 1.43 higher on average, P = 0.01) and a significantly higher mortality rate (37.5% vs. 0.0%, P < 0.01) than non-RAPD patients. Demographic features, BCVA at presentation, EOM limitation at presentation, elevated IOP at presentation, and comorbid orbital cellulitis were not associated with worse visual or mortality outcomes.

CONCLUSIONS

Septic CST may result in permanent ophthalmic functional deficit in almost one-third of cases and mortality in approximately 11% of patients under contemporary management. New RAPD at presentation may indicate higher risk of poor visual and survival outcomes.

Clinical Outcomes of Severe Rhinosinusitis Complicated with Cavernous Sinus Syndrome

Background: Various diseases involving the cavernous sinus can cause a condition called cavernous sinus syndrome (CSS), which is characterized by ophthalmoplegia or sensory deficits over the face resulting from the compression effect of internal structure. While tumor compression is the most reported cause of CSS, statistical data on CSS caused by infections are limited. Its risk factors, treatment methods, and clinical outcomes are not well-documented. Methods: In this retrospective study, we reviewed the data of patients admitted to a tertiary medical center from 2015 to 2022 with a diagnosis of acute and chronic sinusitis and at least one diagnostic code for CSS symptoms. We manually reviewed whether patients were involved in two or more of the following cranial nerves (CN): CN III, CN IV, CN V, or CN VI, or at least one of these nerves with a neuroimaging-confirmed lesion in the cavernous sinus. Results: Nine patients were diagnosed with rhinosinusitis-related CSS. The most common comorbidity was type 2 diabetes, and the most common clinical manifestations were diplopia and blurred vision. The sphenoid sinus was the most affected sinus. One patient expired due to a severe brain abscess infection without surgery. The remaining patients underwent functional endoscopic sinus surgery, and 50% of the pathology reports indicated fungal infections. Staphylococcus spp. was the most cultured bacteria, and Amoxycillin/Clavulanate was the most used antibiotic. Only four patients had total recovery during the follow-up one year later. Conclusions: CSS is a rare but serious complication of rhinosinusitis. Patients with diabetes and the elderly may be at a higher risk for this complication. Even after treatment, some patients may still have neurological symptoms.

Clinical Profile and Long-Term Outcomes in Pediatric Cavernous Sinus Thrombosis

BACKGROUND

Pediatric cavernous sinus thrombosis (CST) is a rare condition with limited data regarding its clinical characteristics and long-term outcomes. The objective of this study was to describe the clinical and radiologic features, diagnostic evaluation, management, and long-term prognosis and to identify clinical variables associated with long-term outcomes in pediatric CST.

METHODS

A retrospective chart review of patients younger than 18 years diagnosed with a CST between 2004 and 2018 at a single center was conducted.

RESULTS

We identified 16 (M:F = 10:6) children with CST with a mean age of 7.6 years (10 days to 15 years) and average follow-up duration of 29 months (3 weeks to 144 months). The most common symptom and examination finding at presentation was eyelid swelling (n = 8). Six patients had bilateral CST. The most common etiologies were sinusitis (n = 5) and orbital cellulitis (n = 5). Treatments included antibiotics (n = 14), anticoagulation (n = 11), and surgery (n = 5). Only one patient died due to intracranial complications. Twelve patients had a normal examination at follow-up. None of the clinical variables including age (P = 0.14), gender (P = 0.09), use of antibiotics (P = 1.00) or anticoagulation (P = 1.00), surgery (P = 0.28), parenchymal abnormalities (P = 0.30), additional cerebral venous thrombosis (P = 0.28), and early versus late commencing of anticoagulation (P = 1.00) were significant when comparing patients with full/partial resolution versus those with no resolution of thrombosis on follow-up neuroimaging.

CONCLUSIONS

Our study is one of the largest cohorts with the longest follow-up data for the pediatric CST. Most of our patients had favorable outcomes at follow-up. We found no statistical difference between clinical variables when comparing patients with full/partial resolution versus those with no resolution of thrombosis on follow-up neuroimaging.

Trombosis bilateral del seno cavernoso en un paciente con enfermedad periodontal y diabetes mellitus. descripción de un caso

La trombosis de los senos cavernosos (TSC) corresponde a una entidad vascular poco usual, asociada con alta morbimortalidad y secuelas neurológicas. La etiología más frecuente son los procesos infecciosos a nivel de cabeza y cuello, que sirven como puerta de entrada para diferentes microorganismos, generando una respuesta inflamatoria que desencadena el evento trombótico. La enfermedad periodontal caracterizada por inflamación gingival, pérdida de tejido conectivo circundante y eventual del diente está asociada con el desarrollo de enfermedades sistémicas secundarias a los patógenos periodontales y mediadores inflamatorios producidos en la cavidad oral. Estos pueden diseminarse y producir complicaciones por contigüidad como eventos trombóticos a nivel del sistema nervioso central. A continuación, se presenta el caso clínico de un paciente que desarrolló una TSC bilateral después de ser sometido a un procedimiento periodontal.

Imaging of orbital infectious and inflammatory disease in children

Most acute nontraumatic periorbital and intraorbital pathologies in pediatric patients have an underlying infectious or inflammatory etiology, and imaging frequently plays a key role in the workup and management of these children. In this paper we review the clinical presentation and imaging findings in children with some of the most common infectious and inflammatory diseases involving the orbit. Basic relevant anatomy and imaging findings on various imaging modalities are also reviewed.

Infectious Cavernous Sinus Thrombosis Presenting as Temporal Arteritis-A Case Report

Cavernous sinus thrombosis (CST) is rare and can present with various nonspecific symptoms. The high mortality rate of this disease is largely due to delayed recognition and treatment. We report a case who presented with unrelenting headache and was diagnosed with temporal arteritis (TA) but did not respond to steroids. Imaging helped make the CST diagnosis and the patient responded well to treatment. This case reiterates the importance of early recognition and treatment of CST, and reminds physicians to include CST as an essential differential diagnosis of TA.

Septic cavernous sinus thrombosis-Case series and review of the literature

BACKGROUND AND PURPOSE

Septic cavernous sinus thrombosis (CST) is a rare, life-threatening disease with infectious thrombosis causing associated complications resulting in high morbidity and mortality. We report a series of CST patients with assessment of arterial and intracranial complications.

METHODS

We used the radiology database from a large, academic tertiary care center to collect all patients treated with CST between 2002 and 2019. Patient demographics, source of infection, treatment course and outcomes were evaluated. A review of the recent literature was also performed for similar reported complications from CST.

RESULTS

14 patients with CST treated during this time period were assessed. Of the 14 patients, 1 patient died. 7 patients had unilateral narrowing of ICA while 3 patients had bilateral narrowing. The ICA narrowing was reversible in 10/12 patients and improvement but persistent narrowing in one patient. One patient had an infectious pseudo aneurysm that was treated by coiling. Extension of thrombosis to the transverse- sigmoid sinuses and internal jugular vein were seen in 3 patients. Three patients had subdural empyema which was treated surgically.

CONCLUSION

The prognosis of CST has improved with advancement in treatment, but complications are not infrequent.
