“…We also noted the presence of tortuosity of the vertebrobasilar system on the site of the lesion and accordingly identified and reported criteria for dolichoectasia of the vertebrobasilar arterial system whenever present according to the Smoker's criteria. The criteria included a diameter of 4.5 mm or more of the vessel (ectasia), evident tortuosity, or laterality of the basilar artery on the site of the disease (Dolicho) [3,20].…”

Purpose Despite being rarely reported, ischemic insults resulting from compromising small brainstem perforators following microvascular decompression (MVD) remain a potential devastating complication. To avoid this complication, we have been using indocyanine green (ICG) angiography intraoperatively to check the flow within the small brainstem perforators. We aim to evaluate the safety and usefulness of ICG videoangiography in MVD. Methods We extracted retrospective data of patients who received ICG videoangiography from our prospectively maintained database for microvascular decompression. We noted relevant data including demographics, offending vessels, operative technique, outcome, and complications. Results Out of the 438 patients, 15 patients with a mean age (SD) of 53 ± 10.5 years underwent intraoperative ICG angiography. Male:female was 1:1.14. The mean disease duration prior to surgery was 7.7 ± 5.3 years. The mean follow-up (SD) was 50.7 ± 42.0 months. In 14 patients, the offending vessel was an artery, and in one patient, a vein. Intraoperative readjustment of the Teflon pledget or sling was required in 20% (3/15) of the cases. No patient had any sort of brainstem ischemia. Eighty percent of the patients (12/15) experienced complete resolution of the spasms. 86.7% (13/15) of the patients reported a satisfactory outcome with marked improvement of the spasms. Three patients experienced slight hearing affection after surgery, which improved in two patients later. There was no facial or lower cranial nerve affection. Conclusion Intraoperative ICG is a safe tool for evaluating the flow within the brain stem perforators and avoiding brainstem ischemia in MVD for hemifacial spasm.

“…There are many causes of vasodilation, including vascular risk factors such as age, gender, hypertension, diabetes, dyslipidemia, obesity, smoking, and so on [ 7 ]. Genetic factors including those leading to abnormal development of muscle fibers, atrophy of the smooth muscle layer, and deficiencies of the intra-arterial elastic lamina, such as autosomal inherited polycystic kidney disease, PHACES syndrome, Marfan syndrome and other diseases have been suggested to be associated with autoimmune factors and validated response factors [ 8 ]. According to the study, VBD predicts an increased risk of ischemic and hemorrhagic stroke, arterial entrapment and arterial dissection in the posterior cranial fossa.…”

Vertebrobasilar dolichoectasia (VBD) is a dilated arterial disease with a diameter ˃4.5 mm. Trigeminal neuralgia (TN) is chronic neuropathic pain. Through the diagnosis and treatment of this case we believe that there is a significant risk associated with the endovascular treatment of VBD. The development of post-operative complications caused some functional impairment to the patient, but the improvement in TN symptoms with this endovascular treatment was unexpected. This treatment procedure was considered to be possibly related to the alteration of the tortuous path of the vessels, changing their course, allowing the displacement of vascular compression in the trigeminal root entry zone, and possibly also altering the hemodynamics of the posterior circulation, improving the progression of ischemia and hypoxia-induced demyelination of the trigeminal nerve. Due to the low incidence of this disease, there are not enough large sample studies for systematic statistical analysis.

“…Dolichoectasia is defined as the abnormal dilation, elongation, and tortuosity of arterial vessels [3]. The reported prevalence is 0.05-0.06%, and the vertebrobasilar circulation is the most frequently affected; in contrast, the anterior cerebral circulation is rarely involved [5]. The precise etiology of dolichoectasia is still unknown, although it has been associated with many diseases such as systemic arterial hypertension, atherosclerosis, collagen-related diseases, polycystic kidney disease, and sickle cell anemia [3].…”

Sudden sensorineural hearing loss (SSNHL) is a syndrome characterized by rapid progression of hearing impairment over seconds to days. While no universally accepted definition exists, it is often defined as a sensorineural hearing loss of 30 decilbles (dB) or more across at least three contiguous frequencies, occurring within 72 hours.In elderly patients and those with vascular risk factors who develop SSNHL, ischemia of the vertebrobasilar territory is suspected, especially of the anteroinferior cerebellar artery. This is because ischemia that affects this artery produces 79% of SSNHL associated with cerebral infarction. In many cases of ischemia of the vertebrobasilar territory, there is an association with anomalies of the vertebrobasilar circulation, such as vertebral artery hypoplasia or vertebrobasilar dolichoectasia.Here, we report a case of a 73-year-old man who presented right sudden hearing loss accompanied by acute onset vertigo, a physical exploration compatible with right vestibular dysfunction, and a history of recurrent episodes of syncope in the context of vertebrobasilar dolichoectasia, as diagnosed via magnetic resonance imaging (MRI).
