“…Asymptomatic, mild, or nonprogressive pelvic AVM can be followed and transrectal endoscopic ultrasonography is useful for monitoring [9]. There are two treatment methods: one is to stop the blood flow with TAE, and the other is to remove the AVM by surgery [10]. TAE is useful for controlling the symptoms and it is less invasive.…”

“…It is a nonabsorbable embolic material, and durability of the embolic effect can be expected compared to conventionally used gelatin particles [11]. Although TAE is a palliative treatment because the nidus remains after treatment, TAE can be repeatedly performed at the time of recurrence; it is a very useful treatment alleviating symptoms and avoiding invasive surgery [10].…”

An 86-year-old man who presented with frequent hematochezia with mild anemia on blood tests was admitted to our hospital. Colonoscopy exhibited a submucosal tumor-like lesion in the lower rectum. CT and MRI showed blood flow into the lesion, but not tumor component. Angiography of the superior rectal artery and left internal iliac artery showed vascular hyperplasia and nidus. Thus, rectal arteriovenous malformation was diagnosed. If bleeding from arteriovenous malformation was out of control, surgical resection was necessary. However, due to the age of the patient, we performed transcatheter arterial embolization and abdominoperineal resection was not needed. Embolization from the left superior rectal artery, middle rectal artery and inferior rectal artery was performed to control the bleeding and to avoid surgery. After embolization, he was followed up for 10 months in our hospital without recurrence.

“…Some alternative concepts have appeared, though. Intraoperative transvenous embolization, preferably with ethylene glycol [10], proves effective in some cases. Another novel method is stent-graft implantation combined with alcohol sclerotherapy [11].…”

SummaryBackground:Congenital arteriovenous malformation (AVM) in the pelvic area is uncommon in males.Case Report:The described case is of a giant lesion of this type that caused recurrent hemorrhaging in the lower part of the gastrointestinal tract. Preliminary diagnosis of vascular pathology was made on the basis of an endoscopic examination that revealed numerous pulsating protuberances of the rectal wall, in which blood flow was identified by means of transrectal ultrasonography. Complementing the diagnostics with a CT revealed a considerable extent of malformation, as well as its morphology and anatomical relations with the surrounding tissues.Results:Following a two-year follow-up period, the malformation did not progress or demonstrate any intensification of clinical symptoms, therefore the patient continues to undergo conservative treatment.

“…The principle goal of therapy for AVMs is to obliterate the nidus, which can be identified angiographically as the physical site where shunting occurs [54]. From an endovascular approach, this requires delivering an embolic agent within the nidus; this can be performed using a transarterial approach, direct percutaneous puncture of the nidus, or a retrograde transvenous approach, all of which have been described [55][56][57]. The consequences of ill-planned or improper treatment, such as misidentification or incomplete obliteration of the nidus, have been shown to stimulate the AVM lesion into a proliferative state.…”

Vascular malformations are congenital lesions caused by errors in endothelial development. Mulliken's classification of vascular malformations subdivides lesions into high-flow (such as arteriovenous malformations) and low-flow lesions (such as venous and lymphatic malformations). Although they can occur virtually anywhere in the body, the majority occur in the head and neck. The therapeutic management of vascular malformations is challenging even for highly experienced practitioners; they are often complex lesions that require a specialized multidisciplinary team approach for optimal treatment. Currently, endovascular therapeutic techniques, such as sclerotherapy, with or without adjunctive surgical resection, are among the first-line treatment options for vascular malformations. There are a wide variety of embolosclerotherapy agents which have been used effectively to treat vascular malformations. This article presents a brief overview of the endovascular management of craniofacial vascular malformations.
