Radiation therapy for intractable bleeding in extremity arteriovenous malformation: Considerations on a clinical case

Arteriovenous malformations are rare clinicopathological entities with varied distribution and a constellation of symptoms. In the extremities they are usually associated with dermatological manifestations, such as angiodermatitis with a potential risk of torrential haemorrhage. Surgical resection is a morbid procedure. Transcatheter embolization and sclerotherapy is an attractive alternative to surgical resection. However, proper case selection is a prerequisite and may not be possible in all the cases. The case reported here is a paradigm of a complex and extensive vascular malformation with torrential haemorrhage where a unique therapeutic approach of radiation therapy was used as an alternative to morbid surgery after embolization and sclerotherapy failure.

“…In the patient presented in this article, a bruit or thrill was not observed because, in arteriovenous malformations of the extremities, the flow is usually through multiple small communications, as other investigators have proposed. 6 Arteriovenous malformations located in the extremities are not believed to shunt enough blood to have a significant effect on the cardiac Volume 119, Number 5 • Vascular Malformation in the Foot system. However, distal shunting has the propensity to significantly reduce the flow rate beyond the shunt and thus induce peripheral ischemia.…”

A case of a patient with a large arteriovenous malformation in the medial plantar aspect and dorsum of the foot is presented. Embolization and surgical management of the malformation allowed a successful outcome, avoiding amputation of the foot and preventing recurrence of the lesion. Although arteriovenous malformations are not frequent entities, they have to be considered in the differential diagnosis of lesions that may affect the lower extremities. The earlier the diagnosis and treatment of these malformations, the lower the morbidity. In large arteriovenous malformations, before radical treatment is envisaged, surgery combined with embolization may achieve good results. CASE REPORTA 33-year-old man with an unremarkable medical history had been diagnosed with arteriovenous malformation of the right foot ( Fig. 1). The patient presented an interdigital ulceration in the first space between the toes, not related to previous trauma. Four years previously, a competent deep venous system had been visualized by echography-Doppler, and saphenectomy and ulcer debridement of the ulceration were performed. However, the ulcer reappeared after the wound was grafted. Two years later, arteriography was performed and provided diagnosis of an arteriovenous malformation located on the dorsum and medial plantar aspect of the right foot. The arteriovenous malformation was dependent on the posterior tibial artery and dorsalis pedis artery.In our department, the patient reported an increasing limitation of daily activities and the inability to wear shoes because of ulceration in the distal dorsal aspect of the right foot. Amputation of the right foot had been advised at another center. Physical examination showed a 4 ϫ 2-cm ulceration with local signs of infection in the first interdigital space of the foot, which extended to the dorsal area ( Fig. 1, above, left). A firm soft-tissue mass was palpable in the medial side of the plantar right foot, extending from the metatarsophalangeal joints to the distal border of the talus (Fig. 1, above, right). It was not pulsatile and the mass lacked a bruit or thrill. There were hyperpigmented changes overlying the lesion in the plantar side of the foot. The extremities were equal and symmetrical in size and appearance. Digital subtraction arteriography showed a high-flow arteriovenous malformation affecting the soft tissue of the dorsal and medial plantar aspects of the right foot (Fig. 1, below, left).The vessels involved in the arteriovenous malformation were the metatarsal plantar branches of the posterior tibial artery and dorsalis pedis artery branches. The posterior tibial artery showed a lobular and tortuous morphology, with aneurysmatic dilatations. Once the extent of the nidus, its blood supply, and its collateral supply had been mapped using digital subtraction arteriography, surgical excision of the lesion was proposed. Magnetic resonance images showed an enlargement of vessels into the flexor muscles of the foot together with an increased signal from the skin paddle (Fig. 1, be...

“…These lesions are low resistance and high flow vascular channels characterized by a central nidus of interconnected arteries and veins without an intermediate capillary network. Congenital maldevelopment is the most common cause of an AVM, although other causes including trauma have been reported [ 2 , 3 , 4 ]. These lesions are formed during fetal development as a result of an abnormal differentiation of the vascular structures.…”

Introduction: Arteriovenous malformations (AVM) are developmental vascular malformations consisting of abnormal arteriovenous shunts surrounding a central nidus. These lesions are relatively uncommon, comprising just 7% of all benign soft-tissue masses. Most AVMs occur in the brain, neck, pelvis, and lower extremity and rarely manifest in the foot. When they do form in the foot, non-specific pain and the absence of clinical features contribute to the high rate of misdiagnosis on initial presentation. Although surgical excision combined with embolotherapy has emerged as the preferred treatment for large AVM, controversy exists over the best treatment for small lesions in the foot. Case Presentation: A 36-year-old Afro-Caribbean man was referred to the clinic with a 2-year history of increasing pain in his forefoot, affecting his ability to stand or walk comfortably. There was no history of trauma, and despite changing his footwear, the patient continued to have significant pain. Clinical examination was unremarkable except for mild tenderness over the dorsum of his forefoot, and radiographs were normal. A magnetic resonance scan reported an intermetatarsal vascular mass but could not exclude malignancy. Surgical exploration and en bloc excision confirmed the mass to be an AVM. One year post-surgery, the patient remains pain-free with no evidence of recurrence. Conclusions: The rarity of AVM in the foot, combined with normal radiographs and non-specific clinical signs, contributes to the long delay in diagnosing and treating these lesions. Surgeons should have a low threshold for obtaining magnetic resonance imaging in cases of diagnostic uncertainty. En bloc surgical excision is an option for treating small suitably located lesions in the foot.
