Introduction: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by arteriovenous malformations (AVM). HHT can have neurological manifestations. Case Report: A 32-year-old woman with a history of HHT presented to the emergency department with acute partial paralysis of the right leg, urinary retention, and right-sided back and hip pain. Magnetic resonance imaging of the spine demonstrated multiple, dilated blood vessels along the cervical spine, diffuse AVMs in the lumbar and thoracic spine, and a new arteriovenous fistula at the twelfth thoracic (T12) vertebral level. Her symptoms improved after endovascular embolization of the fistula. Conclusion: Spinal AVMs are thought to be more prevalent in patients with HHT. Given the high morbidity of arteriovenous fistulas, early recognition and intervention are critical.

Background: Tentorial dural arteriovenous fistula (TDAVF) is a rare intracranial vascular shunt. A TDAVF can be supplied by the Artery of Wollschlaeger and Wollschlaeger (AWW). However, a limited number of cases of TDAVF fed by the AWW have been reported to date. Case Description: A 70-year-old woman complaining of the right motor weakness underwent magnetic resonance imaging. A vascular lesion beneath the cerebellar tentorium was incidentally found with chronic infarction of the left corona radiata. Angiographically, the vascular lesion was a TDAVF supplied by the bilateral posterior meningeal arteries. No other apparent feeders were detected. The TDAVF had a shunting point on the inferior surface of the cerebellar tentorium with venous retrograde flow (Borden type III, Cognard type III). To prevent vascular events, endovascular embolization was performed using n-butyl-2-cyanoacrylate. Following embolization of the shunting point, a residual shunt fed by the AWW was identified. The shunt supplied by the AWW was not observed preoperatively. Follow-up angiography performed 1 week later revealed spontaneous disappearance of the residual shunt. The patient was followed-up in our outpatient clinic, and no recurrence of the TDAVF was confirmed postoperatively. Conclusion: Detection of mild feeding from the AWW to a TDAVF can be elusive preoperatively. Following embolization of the main shunting point, residual shunting from the AWW can resolve spontaneously.

Abstract Objective: Microcatheters retained after Onyx (eV3 Neurovascular, Inc., Irvine, CA) embolization represent a potential source of thromboembolic complications. Catheter retention depends on the degree of Onyx reflux and vessel tortuosity. To overcome this problem, we have adapted a previously described monorail snare technique for stretched coils to remove an adherent microcatheter from the occipital artery during Onyx embolization of a dural arteriovenous fistula. Clinical Presentation: We used this technique successfully in a 62-year-old man with a posterior fossa dural arteriovenous fistula. An Echelon-10 microcatheter (eV3 Neurovascular, Inc.) system became adherent in the right occipital artery because of reflux and vessel tortuosity. Significant stretching of the microcatheter was observed during attempted removal. Intervention: A 2-mm Amplatz Goose Neck microsnare (Microvena Corp., White Bear Lake, MN) was placed through a Rapid Transit microcatheter (Cordis Corp., Miami, FL). The hub of the indwelling Echelon microcatheter was cut off and the snare advanced over the outside of the microcatheter. The snare and Rapid Transit microcatheter were then advanced into the guiding catheter (6-French) as a unit over the indwelling Echelon microcatheter. Using the adherent Echelon as a “monorail” guide, the snare and Rapid Transit microcatheter were advanced distally into the occipital artery and the snare was retracted to engage the microcatheter. The microcatheters and snare were then easily removed because of the second vector of force placed by the snare system on the adherent microcatheter very close to the point of adherence. Conclusion: The monorail snare technique represents a simple and safe way to remove an adherent microcatheter from an Onyx cast during the embolization of dural arteriovenous fistulas. Prospective knowledge of this technique will facilitate more aggressive embolization without the reservation that a retained microcatheter could require surgical removal or anticoagulation.

Introduction: We aim to report an uncommon case of post ERCP perforation that effectively managed conservatively in non-hepatobiliary surgery centre. Case report: A 46-year-old man diagnosed to have obstructive jaundice secondary to distal common bile duct (CBD) stone. He underwent ERCP at a private centre, sphincterotomy was performed, but, the operator had failed to insert the stent and complicated with post ERCP perforation evidenced by contrast extravasation beyond 1/3rd of the CBD and referred to our centre. Patient was subjected for re ERCP. There were difficulties in cannulating the CBD and stent was inserted. Cholangiogram revealed contrast leak around the pancreatic duct and bifurcation of hepatic duct. There was no evidence of CBD stone. Computed Tomography (CT) of the abdomen revealed extensive subcutaneous emphysema on the right side of the abdomen to right inguinal region, extensive retroperitoneal free air and pneumoperitoneum, but there were no free fluid or contrast extravasation. The patient subjected for non-operative management (NOM) for the complication and kept fasting with total parenteral nutrition and intravenous antibiotic. He recovered well with the opted management. Patient was programmed with Gastrograffin study after 10 days that showed no evidence of contrast leak to suggest free bowel injury. He was allowed orally after that and was discharged well after 15 days with stent in situ. During follow up, he was well, and the stent removed after 3 months. Patient planned for laparoscopic cholecystectomy and on table cholangiogram. Conclusion:  Post ERCP perforation is uncommon but lethal. Early recognition of the complication is crucial hence appropriate management can be arranged to avoid death. To date, surgery is not the only choice available to manage this complication.

Introduction. Arteriovenous malformations (AVM) of the head represent the rare lesions that have a congenital, traumatic or post-infectious nature. In the last decade, endovascular methods have become the most prevalent in the treatment of AVM. Staged embolization is performed to achieve maximum effect and minimize the complications.Case report. A 30-year-old female patient is presented with complaints of enlarged vessels in the frontal and parietal regions. CT-angiography scan and cerebral angiography showed extracranial AVM of the fronto-parietal regions with afferent vascular supply from the right and left superficial temporal and ophtalmic arteries with significant expansion of the afferent arteries and the presence of varix dilatation of the draining veins. Two-stage endovascular embolization of AVM was performed. The first stage was embolization of the afferent vessels from the left superficial temporal artery system with exclusion of 60–65% AVM volume. Three months later, the second stage was performed with embolization of the afferent vessels from the right superficial temporal artery system and the exclusion of 75–80% of the residual volume of AVM. The non-adhesive composition SQUIDR12 (Emboflu, Switzerland) and glue composition PHILR25% (Microvention, USA) were used. A good aesthetic effect was achieved. Postoperative complications were not observed. There was no recurrence during the observation within a year.Summary. The staging and the use of various liquid embolization agents in the treatment of AVM of the head allow to achieve a good aesthetic outcome and prevent complications associated with facial soft tissue necrosis.
