ABSTRACT

Paraclinoid internal carotid artery (ICA) aneurysms are associated with a high mortality rate, which gradually increases without intervention. Surgical clipping or coiling of large aneurysms with inadequate neck and adductor artery expansion will not guarantee a successful outcome. Carotid surgical trapping or endovascular occlusion of the adductor artery can help to isolate the aneurysm from circulation, but it comes at the expense of sacrificing a major blood vessel responsible for significant cerebral perfusion. Currently, a technique has been developed to redirect blood flow and stimulate gradual thrombosis in the aneurysm cavity to reduce pressure on its walls. However, in cases of recurrent aneurysm and stent thrombosis in these patients, it is necessary to consider destructive surgery. The 65-year-old patient, who had a history of migraine, was diagnosed with a large aneurysm. He was initially treated with the Pipeline Flex stent from Medtronic, but after 5 months, he experienced 2 transient ischemic attacks. Subsequent CT scans revealed no signs of brain damage, but a brain CTA revealed the recurrence of an internal carotid artery paraclinoid aneurysm with the occlusion of the pipeline device and contrast flowing parallel to the aneurysm wall. This case is an example of successful recanalization of an occluded flow diverter device in a patient with recurrent internal carotid aneurysm.

ABSTRACT

OBJECTIVE: In the present study, we investigated the clinical outcomes after gonadal vein resection (GVR) and gonadal vein embolization (GVE) with coils in patients with pelvic venous disorder (PeVD). We also assessed the rates of procedural complications and disease recurrence. METHODS: Our multicenter retrospective cohort study included 361 female patients with PeVD-related chronic pelvic pain (CPP) and gonadal vein reflux who underwent GVR (n = 184) or GVE with coils (n = 177) from 1999 to 2020. The clinical outcomes (ie, presence and severity of CPP, procedural complications, disease recurrence) were assessed at 1 month and 1, 3, and 5 years after intervention. The pain intensity before and after treatment was assessed using a visual analog scale. All the patients underwent duplex ultrasound after GVR and GVE, and those with persistent CPP and suspected perforation of the gonadal vein by the coils were also evaluated by multiplanar pelvic venography. RESULTS: GVR and GVE was associated with the reduction or elimination of CPP at 1 month after treatment in 100% and 74% of patients and postprocedural complications in 14% and 37% of patients, respectively (Р < 0.01 for both). The most common complication after either GVR or GVE was pelvic vein thrombosis (11% and 22% patients, respectively; P < .01 between groups). GVE was associated with postembolization syndrome in 20%, coil protrusion in 6%, and coil migration in 1% of patients. The long-term recurrence rate after GVR and GVE was 6% and 16%, respectively (P < .01). CONCLUSIONS: Both GVR and GVE were found to be effective in treating patients with PeVD. However, GVR was associated with better efficacy in the relief of CPP and lower rates of procedural complications and disease recurrence.

ABSTRACT

INTRODUCTION: To investigate and compare complications after gonadal vein embolization (GVE) with coils and gonadal vein resection (GVR) in patients with pelvic venous disorder (PeVD). METHODS: This single-center retrospective cohort study included 277 female patients with PeVD who underwent GVE with coils (n = 150) or GVR (n = 122) in the period from 2000 to 2020. The participants were selected from a cohort of 4975 patients with chronic pelvic pain (CPP), of whom 1107 suffered from the PeVD-related CPP and 305 underwent surgical or endovascular intervention on the gonadal veins. The GVR technique was open retroperitoneal in 92, endoscopic transperitoneal in 18, and retroperitoneal in 12 patients. Clinical outcomes included 30-day complication rates and 3-year PeVD recurrence rates. The pain intensity was assessed before and after the procedure using a visual analogue scale. All patients underwent duplex ultrasound after the procedure, and those with persisting pain and suspected gonadal vein perforation with coil were also examined using computed tomographic venography. RESULTS: A substantial pelvic pain relief was achieved within 30 d after GVE and GVR in 73% and 100% patients, accordingly (Р = 0.001). Complications after GVE were identified in 85 (56%) patients. The major complications included pelvic vein thrombosis (PVT) and calf deep vein thrombosis (24%), postembolization syndrome (22%), and coil protrusion (5.3%). Complications after GVR occurred in 14 (11%) patients and consisted of PVT (10%) and ileus (1.6%). The 3-year recurrence rates after GVE and GVR were 11% and 5%, accordingly (P = 0.04). CONCLUSIONS: In patients with PeVD, the gonadal vein embolization with coils is associated with a high complication rate, which can be reduced with further development of the GVE technique, the use of new embolic agents, and the selection of a treatment method based on the patient's body composition.
