Short-term experience with aspiration embolectomy using a ACE68 reperfusion catheter to treat embolic superior mesenteric artery occlusion.

We report the short-term results with aspiration embolectomy using an ACE68 reperfusion catheter to treat patients with acute embolic superior mesenteric artery (SMA) occlusion. Our study included 4 consecutive male patients ranging in age from 72 to 86 years (mean age 79 years). In all patients, the main trunk of the SMA was occluded. The technical success rate was 100% for all procedures. There were no major procedure-related complications. One patient underwent laparotomy with intestinal resection after successful recanalization. No patient reported clinical symptoms of abdominal ischemia at follow-up. Our short-term experience shows that percutaneous aspiration embolectomy using an ACE68 reperfusion catheter is an effective treatment for acute mesenteric ischemia.

[A Case of Anterior Cranial Fossa Dural Arteriovenous Fistula Involving Uncontrolled Seizures Diagnosed Based on Characteristic Findings on Arterial Spin-labeling Imaging].

We report a case of anterior cranial fossa dural arteriovenous fistula(ACF-DAVF)in a patient whose diagnosis was made according to characteristic findings on arterial spin labeling(ASL)MRI. CASE:A 68-year-old man was admitted to our hospital because of intractable epilepsy. Based on the initial MRI findings, an initial diagnosis of limbic encephalitis was made. Steroids and anticonvulsant drugs were administered;however, the seizures could not be controlled. A second MRI with ASL revealed abnormal vessel signals in the base segments of the left frontal and temporal lobes toward the basal vein of Rosenthal. Digital subtraction angiography(DSA)revealed an arteriovenous shunt in the left anterior cranial fossa, which drained toward the medial side of the left temporal lobe. A diagnosis of ACF-DAVF with status epilepticus was made, and the main drainer was cauterized. After the surgical procedure, the epilepsy was controlled with antiepileptic drugs, and postoperative MRI revealed obliteration of ACF-DAVF, disappearance of the high-intensity area on FLAIR sequences, and disappearance of the high-intensity signal area on ASL.
