We describe our experience of the development of contralateral de novo intraosseous AVMs in a ten-year-old girl with AVMs of the mandible who underwent endovascular embolotherapy. She initially presented with intermittent oral bleeding. Computed tomography and digital subtraction angiography demonstrated intraosseous AVMs within the right mandible. The AVMs were treated by transosseous direct-puncture and transarterial embolization with Guglielmi detachable coils and n-butyl cyanoacrylate glue. However, de novo intraosseous AVMs developed within the previously healthy contralateral mandible and resulted in dangerous oral bleeding. Therefore, we suggest regular follow-up and prompt retreatment of any residual mandibular AVMs in patients undergoing endovascular or surgical treatment to prevent subsequent development of “secondary” AVMs and life-threatening oral bleeding.

The development of a de novo arteriovenous malformation (AVM) in patients with moyamoya disease is extremely rare. A 14-year-old girl developed an AVM in the right occipital lobe during the 4-year postoperative period following successful bilateral revascularization surgeries. She suffered a transient ischemic attack with hemodynamic compromise of the bilateral hemispheres at the age of 10 years. Results of an initial examination by 1.5-T MRI and MR angiography satisfied the diagnostic criteria of moyamoya disease but failed to detect any vascular malformation. Bilateral direct and indirect revascularization surgeries in the anterior circulation relieved her symptoms, and she underwent MRI and MR angiography follow-up every year after surgery. Serial T2-weighted MRI revealed the gradual appearance of flow voids in the right occipital lobe during the follow-up period. Magnetic resonance angiography ultimately indicated the development of an AVM 4 years after these surgeries when catheter angiography confirmed the diagnosis of an AVM in the right occipital lobe. The AVM remained asymptomatic, and the patient remained free of cerebrovascular events during the time she was observed by the authors. Acquired AVM in moyamoya disease is extremely rare, with only 3 pediatric cases including the present case being reported in the literature. The development of a de novo AVM in a postoperative patient with moyamoya disease appears to be unique, and this case may provide insight into the dynamic pathology of AVMs.

The artery of Desproges-Gotteron is rarely mentioned in the literature and is unfamiliar to most neurosurgeons. The authors report a unique case of an arteriovenous malformation (AVM) of the conus in an adult woman, which received blood supply from an artery of Desproges-Gotteron. The patient presented with intermittent pain radiating down the right posterior thigh and foot and transient bladder incontinence. On examination, there was weakness of the right lower limb with hypalgesia of the plantar aspect of the right foot. Magnetic resonance imaging revealed a mass near the anterior aspect of the conus medullaris and angiography confirmed a spinal AVM at the L-1 level and a shunt located at the inferior L-3 level. The patient underwent transarterial embolization, and at 2-year follow-up, repeat angiography demonstrated no evidence of residual or recurrent spinal AVM, intermittent and tolerable pain without treatment interventions, and a normal neurological examination. The artery of Desproges-Gotteron appears to be a rare arterial variation. Moreover, the authors believe this to be the first case of a conal AVM supplied by such an artery. The anatomy and implications of such an arterial variant are discussed.

Well-differentiated papillary mesothelioma (WDPM) is an uncommon mesothelial tumor. The lesions may be single or multiple and usually behave in a benign or indolent fashion, sometimes persisting for many years. In the present case, a 37-year-old woman had experienced primary infertility for 12 years, and a diagnostic laparoscopy was performed. Approximately 200 mL of dark red, free fluid in the pelvis and more than 10 yellow-white nodules on the surface of the right round ligament, sacrum ligament, right fallopian tube, and both sides of the uterus were found. A lesionectomy was performed and immunohistochemical markers indicated WDPM with adenomatoid tumor. The patient was monitored by computed tomography and serum CA125 (cancer antigen 125) levels for 49 months with no recurrence. WDPM and adenomatoid tumor are both benign tumors of mesothelial origin. Because of the lack of effective radical treatment, regular follow-up is sufficient. However, the effects of estrogen and progesterone on WDPM and adenomatoid tumors during ovulation or pregnancy remains unclear. Although WDPM is not life threatening, a strategy to fulfill the fertility requirements of women with this condition is a new challenge for infertility doctors.

Abstract Background Endoscopic cyanoacrylate (glue) injection of fundal varices may result in life-threatening embolic adverse events through spontaneous gastrorenal shunts (GRSs). Balloon-occluded retrograde transvenous occlusion (BRTOcc) of GRSs during cyanoacrylate injection may prevent serious systemic glue embolization through the shunt. This study aimed to evaluate the efficacy and safety of a combined endoscopic–interventional radiologic (BRTOcc) approach for the treatment of bleeding fundal varices. Methods We retrospectively analysed the data of patients who underwent the combined procedure for acutely bleeding fundal varices between January 2010 and April 2018. Data were extracted for patient demographics, clinical and endoscopic findings, technical details, and adverse events of the endoscopic–BRTOcc approach and patient outcomes. Results We identified 30 patients (13 [43.3%] women; median age 58 [range, 25–92] years) with gastroesophageal varices type 2 (53.3%, 16/30) and isolated gastric varices type 1 (46.7%, 14/30) per Sarin classification, and median clinical and endoscopic follow-up of 151 (range, 4–2,513) days and 98 (range, 3–2,373) days, respectively. The median volume of octyl-cyanoacrylate: Lipiodol injected was 7 (range, 4–22) mL. Procedure-related adverse events occurred in three (10.0%) patients, including transient fever, non-life-threatening pulmonary glue embolism, and an injection-site ulcer bleed. Complete gastric variceal obturation was achieved in 18 of 21 patients (85.7%) at endoscopic follow-up. Delayed variceal rebleeding was confirmed in one patient (3.3%) and suspected in two patients (6.7%). Although no procedure-related deaths occurred, the overall mortality rate was 46.7%, primarily from liver-disease progression and co-morbidities. Conclusion The combined endoscopic–BRTOcc procedure is a relatively safe and effective technique for bleeding fundal varices, with a high rate of variceal obturation and a low rate of serious adverse events.

We report on a 59-year-old female with symptomatic cholelithiasis on a background of morbid obesity who underwent an elective LC with an uncomplicated intraoperative course; however, she experienced a refractory hypotension within one hour postoperatively with an acute haemoglobin drop requiring fluid resuscitation and blood transfusion. A triphasic computed tomography scan revealed a large intrahepatic subcapsular haematoma (ISH) measuring 21   cm × 3.1   cm × 17   cm surrounding the lateral surface of the right hepatic lobe without active bleeding. She was managed conservatively with serial monitoring of haemoglobin and haematoma size. A follow-up ultrasound scan after eight weeks confirmed complete resolution of the haematoma. Giant ISH is a fairly rare, but life-threatening complication following LC which merits special attention. This case demonstrates the necessity of close postoperative monitoring of patients undergoing LC and considering the possibility of ISH, although being rare event, in those who experience a refractory postoperative hypotension. It also highlights the decisive role of diagnostic imaging in securing a timely and accurate diagnosis of post LC-ISH.

Endovascular treatment of high flow arteriovenous fistula following a stab wound injury in a 25 year old man is reported. Previously performed proximal embolisation and surgical ligation failed to occlude the fistula but resulted in changes to the normal vascular anatomy and significant clinical and cosmetic disturbances. A direct puncture of the draining vein was performed and the fistulous connection occluded by placement of detachable coils and deposition of glue. Follow-up showed disappearance of the AVF as well as complete clinical recovery.

Abstract Background Congenital lobal emphysema (CLE) is a developmental lung abnormality usually diagnosed in the neonatal period and is rarely observed in adults. Adults with CLE are usually asymptomatic and only a small fraction may present with coughing, recurrent pneumonia and respiratory distress. In imaging studies, the most frequently affected lobe of CLE is the left upper lobe, followed by the right middle lobe. However, multilobar involvement with severe mediastinal shift is extremely rare. Case presentation We report a case of fatal CLE in a 28-year-old puerpera with postpartum respiratory failure. Chest computed tomography (CT) revealed emphysema of the right upper, middle and lower lobes resulting in adjacent atelectasis. Hyperinflation of the right upper lobe crossed the midline, leading to a deviation of the mediastinal structure to the left hemithorax and severe compression of the left lung. Conclusions Early and timely diagnosis of CLE with routine follow-up is necessary for patients. CLE, especially with multilobar involvement or mediastinal shift, could be life-threatening and should be promptly and aggressively treated to prevent severe complications.

Abstract BACKGROUND AND IMPORTANCE Few studies describe the use of adenosine-induced cardiac systole for treatment of cerebrovascular pathologies. We describe a midbrain arteriovenous malformation (AVM) treated with transvenous embolization using adenosine-induced asystole to achieve transient systemic hypotension with the purpose of furthering discussion on the technique and operative considerations for adenosine use in endovascular AVM treatments. CLINICAL PRESENTATION A 29-yr-old man presented with sudden onset of severe bilateral headache, blurred vision, and numbness on the right side of his face and tongue. Noncontrast head computed tomography revealed fourth ventricle hemorrhage. Diagnostic cerebral angiography revealed a high-flow midbrain AVM with a posterior wall perforator from the basilar artery terminus and a draining vein into the straight sinus. Transarterial AVM embolization was successful. The patient was discharged with no residual neurological deficits but returned 1 wk later with slurred speech and left-sided dysmetria. Repeat angiography revealed partial AVM filling. Attempts at transarterial embolization were unsuccessful. Thus, transvenous AVM embolization with adenosine-induced cardiac asystole and systemic hypotension was performed. A total of 60 mg of adenosine was administered, followed by 2 additional doses of 60 and 40 mg; and complete cardiac asystole with a mean arterial pressure of 40 mmHg was maintained, resulting in successful embolization of the AVM. No residual filling was visualized on postembolization arterial angiography runs. The patient was neurologically stable and discharged on postoperative day 2. CONCLUSION With appropriate and safe dosing, adenosine-induced asystole and systemic hypotension may be a feasible, safe option to reduce flow and assist endovascular transvenous embolization of high-flow AVMs.

Background Ureteral arterial fistulas are rare but potentially life threatening. We present a female who developed a ureteral arterial fistula following a right robotic nephrectomy. After several endovascular interventions to control the bleeding had failed, we approached the fistula through the right ureteral stump with coil embolization. Methods Coil embolization of the right ureteral stump was performed. We utilized a 6Fr × 45 cm sheath inserted through one of the cystoscope channels to cannulate the right ureteral orifice. We then performed a retrograde ureterogram. After, we were able to visualize full length of the ureter, ahd we began placing several 10–12 mm Nester coils to pack the ureter and tamponade the fistula for hemostasis. After the ureter was packed, we injected 1 g of Vancomycin into the ureter. The sheath and cytoscope were removed and the patient did well and was sent to the recovery room. Results Postoperatively, the patient had no complaints of hematuria and her hemoglobin level remained unchanged. She was observed for a few days prior to being discharged to home. The patient’s follow-up at six months revealed resolution of her hematuria. Conclusion Ureteral arterial fistula is a potentially life-threatening condition. Endovascular stenting has provided a safe, reliable alternative to open surgery. However, when endovascular options are not satisfactory, coil embolization of the ureteral stump may serve as a safe and effective alternative treatment for these cases.

Life-threatening bleeding in the head and neck region requires urgent management. These hemorrhagic lesions, for example, a ruptured pseudoaneurysm, are often treated by transarterial embolization (TAE), but prior intervention or surgery, inflammation, anatomic variants, and vessel tortuosity may render an endovascular approach challenging, time-consuming, and sometimes impossible. We report two cases of severe head and neck hemorrhages successfully embolized with n-butyl cyanoacrylate via direct puncture, and propose this approach as a fast, safe, and effective alternative to TAE.
