Arteriovenous malformation (AVM)-related aneurysms have been described in the literature. Their behavior varies based on their location in relation to and the activity of the shunting through the index AVM. The intuitive expectation supported by numerous reports is that these aneurysms should regress if the AVM is excluded from the circulation. We describe a case of 46-year-old man who presented with a posterior fossa AVM with an aneurysm on the posterior inferior cerebellar artery feeding the AVM. The nidus of the AVM was successfully excluded by glue embolization, with initial regression of the PICA aneurysm on serial imaging. Five years after the endovascular treatment, the aneurysm showed significant re-growth necessitating endovascular coiling. This case presents the re-growth of an AVM-related aneurysm and emphasizes the importance of long-term follow-up of such aneurysms even if the AVM is completely excluded.

Background: Hemodynamic flow is one of the major factors in the progression and rupture of intracranial aneurysms (IA). Flow diverter devices (FD) reduce blood flow in the aneurysm sac, allow gradual stagnation, thrombosis and neointimal remodeling while maintain outflow in the side branches and perforators. Objectives: We present our experience and long-term follow-up on endovascular reconstruction of complexes IA using flow diverter device. Particularly we analyze our experience with (Pipeline endovascular device) PED. Methods: Since March 2006 to July 2015, 1000 patients (pt) with IA were treated with FD or FD/coils. Of this group 633 pt were with PED, 113 Surpass (SNEG), 111 P64, 78 Cardiatis, 40 WEB and others 25. Angiographic follow-up was performed at 3, 6, 12 months and yearly until 8 y Fup. An inclusion criteria was unfavorable anatomy for coil, dome to neck ratio ≥ 2, Neck ≥ 4 mm and recurrence following previous treatment. Results: We treated 633 Pt with 704 IA with 932 PED. (77 % female); mean age 55 y (range 7-88). History of SAH was present in 18,5%; 81,5% were unruptured IA; mass effect in 125 pt; incidental IA 96 pts; headache 77 pts, others 23 pts. Large/giant IA were present in 51,2%, and wide neck (>4mm) 65%. The technical success was 98,4%. Occlusion rate at 1yr was 90 % and 8 yr 100 %, without recurrences. Peri-procedural (30 days) morbi-mortality rate was 5.9%: 2.7% had definitive neurologic defects; death rate was 3.2%. Conclusion: Endovascular treatment of complex IA with FD is a safe, effective and stable procedure, with an acceptable morbi-mortality rate.

Long Term Follow Up

Vaginal bleeding can occur shortly after delivery in 3%–5% of newborns as a consequence of placental hormone withdrawal . Although usually benign, its differential diagnosis includes central precocious puberty, tumours and other pathological conditions. A girl born at 26 weeks of gestation presented with five episodes of vaginal bleeding, each lasting less than a week, initiated at 4 months of age. Luteinising hormone and oestradiol levels were in the pubertal range. Later, she exhibited breast development, with no other pubertal signs. An ultrasonography test revealed an impregnated endometrium and a right ovarian cyst with 43 mm of diameter. A cranioencephalic MRI was unremarkable. Clinicians adopted expectant management and there was clinical, hormonal and radiological resolution in 3 months. The spontaneous resolution suggested mini-puberty of infancy. This is usually an asymptomatic condition, but to date, four cases of an exacerbated form in extremepremature infants have been reported. Long-term follow-up data are missing.A girl born at 26 weeks of gestation presented with five episodes of vaginal bleeding, each lasting less than a week, initiated at 4 months of age.

The Pipeline Embolization Device (PED) was approved for the treatment of intracranial aneurysms from the petrous to the superior hypophyseal segment of the internal carotid artery. However, since its approval, its use for treatment of intracranial aneurysms in other locations and non-sidewall aneurysms has grown tremendously. The authors report on a cohort of 15 patients with 16 cerebral aneurysms that incorporated an end vessel with no significant distal collaterals, which were treated with the PED. The cohort includes 7 posterior communicating artery aneurysms, 5 ophthalmic artery aneurysms, 1 superior cerebellar artery aneurysm, 1 anterior inferior cerebellar artery aneurysm, and 2 middle cerebral artery aneurysms. None of the aneurysms achieved significant occlusion at the last follow-up evaluation (mean 24 months). Based on these observations, the authors do not recommend the use of flow diverters for the treatment of this subset of cerebral aneurysms.
