Abstract

Background: Antiphospholipid syndrome is a complex autoimmune condition associated with the formation of recurrent thrombosis in any vascular bed throughout the body. Jugular vein thrombosis is very rare with only a 0.9% occurrence and is not typically associated with cerebrospinal rhinorrhea as a result of raised intracranial pressure.

Case Description: A 54-year-old patient presented with a 9-month history of cerebrospinal fluid (CSF) rhinorrhea and headache on a background of antiphospholipid syndrome. Investigations showed a superior vena cava (SVC) and right internal jugular vein (IJV) obstruction with moderately elevated intracranial venous pressures. Her magnetic resonance imaging (MRI) brain was consistent with a CSF leak. The patient underwent successful endovascular stenting of her obstructed SVC and right IJV followed by surgical repair of a herniating meningocele in the posterior left ethmoid air cells.

Conclusion: CSF rhinorrhea is uncommon and never previously reported associated with SVC thrombosis induced by antiphospholipid syndrome. A combination of endovascular techniques and surgical repair is recommended for this challenging presentation.

INTRODUCTION

Cerebrospinal fluid (CSF) rhinorrhea is an uncommon condition classified as either traumatic or nontraumatic and is the result of a pathway formed between the subarachnoid space and the nasopharynx or nasal cavity. Traumatic causes include blunt force injuries and surgical complications.[ 4 , 6 ] Our patient gave no history of trauma. Being an overweight female, she was a classic presentation for raised intracranial pressure (ICP) secondary to benign intracranial hypertension, but she had no intracranial venous sinus abnormalities.

Antiphospholipid syndrome is a complex autoimmune condition with complications, including the formation of recurrent thrombosis in any vascular bed throughout the body.[ 1 , 5 ] It can have severe and life-threatening outcomes, due to the recurring nature of the associated thrombotic events, which necessitates life-long anti-coagulation.[ 1 ] Deep vein thrombosis is the most common peripheral thrombosis with the Euro-Phospholipid project reporting a 38.9% occurrence within their cohort with jugular vein thrombosis being much rarer with only a 0.9% occurrence.[ 5 ] Our patient’s background included antiphospholipid syndrome with chronic thrombosis of the superior vena cava (SVC) and right internal jugular vein (IJV).

We present an unusual case of a patient who presented with CSF rhinorrhea secondary to raised ICP as a result of an SVC and right IJV thrombosis due to antiphospholipid syndrome.

CASE PRESENTATION

A 54-year-old female presented with a 9-month history of spontaneous CSF rhinorrhea associated with blurred vision and headache. This is on a background of antiphospholipid syndrome for which she requires life-long anti-coagulation with warfarin. She also has a history of several deep vein thromboses and pulmonary emboli as well as a near total, chronic thrombosis of her SVC.

Investigations and treatment

She was admitted to the hospital and investigated with an MRI brain demonstrating fluid in the left posterior ethmoid air cells as well as optic nerve sheath enlargement bilaterally, consistent with intracranial hypertension and CSF leak [ Figure 1 ]. A venogram and manometry were also performed, which confirmed the presence of SVC obstruction with extensive venous collaterals [ Figure 2 ] as well as a separate near-complete obstruction of the right IJV at the level of C4 downward. Moderately elevated ICPs were also reported (superior sagittal sinus 22 mmHg), with no intracranial venous gradient and no venous sinus abnormality.

Based on the clinical and radiological findings, a multidisciplinary decision was made to proceed with a combined interventional neuroradiology procedure to stent the SVC and right IJV before endoscopic endonasal repair of the skull base defect.

Under general anesthetic, a 6F Cook Shuttle sheath was introduced through the right common femoral vein. A second venotomy was performed with a 5F short sheath placed in the right IJV and a venography showed severe stenosis of the right IJV at the level of C4 with extensive collaterals flowing into a distended azygos vein. A second severe stenosis was noted in the SVC above the junction with the azygos vein. A communicating channel between the upper and lower SVC was selected from above with a 035 guide wire and an Amplatz super stiff exchange wire was passed to the right common iliac vein. A 10F short sheath was exchanged into the right common femoral vein and a Gooseneck 15 mm device was used to ensnare the exchange wire. Graduated balloon angioplasty (6 mm × 40 mm and 10 mm × 40 mm Advance balloons) of the stenosed SVC was performed and a 16 mm × 40 mm Venovo stent was subsequently deployed over the narrowed segment. A post-stent angioplasty was also completed with a 14 mm × 40 mm XXL balloon. The stenosed section of the right IJV also underwent balloon dilatation (12 mm × 40 mm Advance balloon).

Successful stenting of the patient’s SVC and balloon dilatation of her right IJV [ Figure 3 ] resulted in an improvement in her headaches and blurred vision. The CSF rhinorrhea persisted, and she proceeded to endoscopic endonasal repair of the CSF leak, after 2–3 days.

A preoperative intrathecal injection of fluorescein was used to localize the origin of the leak. An endoscopic approach was employed with a left antrostomy and bilateral ethmoidectomy performed to access the posterior ethmoid space. The source of the leak was identified as a herniating meningocele in the left posterior ethmoid [ Figure 4 ]. The meningocele was reduced and resected with a subsequent vascularized septal mucosal flap raised and rotated to conceal the defect.

Outcome and follow-up

Following the operation, the patient recovered well and her symptoms continue to improve. There was no further rhinorrhea. She was commenced on a heparin infusion postoperatively and then converted to aspirin and warfarin. She was followed up 6 weeks post-intervention with complete resolution of her CSF leak as well as headache and vision. Her postoperative MRI demonstrated an adequate septal flap placement and replacement of the previous posterior ethmoid fluid with diffuse postoperative changes of chronic sinusitis. Contrast computed tomography of the chest confirmed the patency of the SVC stent. She was returned to her hematologist for the long-term management of her antiphospholipid syndrome.

DISCUSSION

CSF rhinorrhea is an uncommon presentation that can result in serious complications such as bacterial meningitis if left untreated.[ 4 ] There are many underlying etiologies and a thorough understanding of the cause is required to guide treatment decisions.[ 9 ]

There has not been a published case describing a patient whose antiphospholipid syndrome was associated with the incidence of CSF rhinorrhea. This may be due to the rarity of chronic nonmalignant SVC syndrome induced by antiphospholipid syndrome resulting in CSF rhinorrhea.[ 5 ] This downstream occlusion impairs venous outflow, thus disrupting CSF absorption.[ 3 ] This can lead to an abnormally increased ICP, shown to be associated with nontraumatic spontaneous CSF rhinorrhea.[ 4 ]

Surgical endoscopic endonasal repair is the preferred treatment method with good outcomes for most causes of CSF rhinorrhea.[ 2 , 6 , 9 ] However, we considered that surgical treatment would not alleviate our patient’s increased ICP due to the presence of chronic SVC obstruction. Endovascular stenting is an effective and appropriate first-line intervention for nonmalignant SVC syndrome and many patients with benign intracranial hypertension. Studies have shown short-term efficacy for endovascular treatment but there is the absence of substantial data for long-term outcomes with a high likelihood for repeat intervention.[ 7 , 8 ] Our patient tolerated the procedure well with immediate improvement in symptoms.

CONCLUSION

CSF rhinorrhea secondary to SVC obstruction resulting from antiphospholipid syndrome has never been reported in the literature. Surgery is the main treatment modality for CSF leak; however, in this case, stent treatment for the SVC obstruction was also required to alleviate the patient’s raised ICP. Therefore, a combined endovascular and surgical approach is recommended for this challenging presentation.
