Things are not what they seem neurologically and radiologically: An apt descriptor for spinal dural arteriovenous fistula (SDAVF).

Spinal dural arteriovenous fistulas (SDAVF) are the most common vascular malformations affecting the spinal cord. It is infrequently encountered in clinical practice and is believed to be acquired, predominantly affecting middle-aged and elderly men with unknown etiology. It is usually misdiagnosed despite presenting with conventional clinical findings and radiological features. Insidious onset of myelopathic findings is seen in addition to pathognomonic findings of cord edema and intrathecal flow voids on MRI. We present a case of SDAVF that was missed by the treating orthopedic surgeon and underwent spinal decompression with subsequent persistence of myelopathic symptoms. Angiography is required to confirm the diagnosis location of the fistula. Treatment is with embolization using liquid embolic agents or surgical through ligation of the draining vein. Endovascular techniques are minimally invasive, safe, and effective. Knowledge of the characteristics and advantages/disadvantages of each agent helps in planning and appropriate selection of agents for the patient. We report successful embolization with improved clinical outcomes for the patient using precipitating hydrophobic injectable liquid (PHIL) embolic agent. The outcome and prognosis of SDAVF depend on the duration of symptoms, severity of neurological symptoms, and successful occlusion of the fistulous draining vein. Awareness of this rare condition amongst clinicians and radiologists, would enable an earlier diagnosis and avoid morbid outcomes of this treatable condition.

Corking the WEB and coiling through a jailed microcatheter: WEB assisted coiling, a useful technique avoiding the use of stents in treating wide-necked large intracranial aneurysms.

The WEB is an endovascular flow-disrupting device used in treating wide-necked intracranial aneurysms. Although the device is available in varying sizes, large aneurysms pose a challenge with the need for custom-made devices. We describe the use of coils as an adjunct to the WEB device in successfully treating large aneurysms in two patients, one with an acutely ruptured aneurysm. This novel technique of jailing a microcatheter, deploying the WEB and then coiling the aneurysm saves the need for intracranial stenting, thereby avoiding the need for antiplatelet therapy, which is of benefit in the setting of acute aneurysm rupture.

Gas Embolic Stroke Secondary to Bowel Infarction.

A 69-year-old gentleman with metastatic esophageal adenocarcinoma presented with acute abdominal pain to the emergency medicine department and subsequently developed an acute left hemiplegia while in the resuscitation unit. An unenhanced computed tomography (CT) scan of the head showed right frontal cerebral gas emboli while an unenhanced CT scan of the abdomen and pelvis showed extensive portal venous gas and pneumatosis intestinalis, presumed secondary to bowel infarction.

Pelvic congestion syndrome.

Pelvic congestion syndrome (PCS) is an important cause of chronic pelvic pain in female patients. Chronic pelvic pain, defined as lower abdominal or pelvic pain for a duration of 6 months or more, causes significant morbidity and results in a large number of diagnostic laparoscopies. It is of utmost importance to identify treatable causes of chronic pelvic pain, one of which is PCS. The etiology, clinical features, investigations, and treatment options in PCS have been discussed in this paper.
