ABSTRACT

BACKGROUND:

We present an interesting case of a 55-year-old male with a large left chest mass after significant cutaneous bleeding. Computed tomography angiogram of the chest revealed arteriovenous malformation with blood supply from sub-branches of the left subclavian artery, left internal mammary artery, and left external carotid artery. Measuring 5.0 × 14.0 × 10.8 cm, the mass extended superior to the clavicle and inferior to the third rib with medial and lateral borders at the level of the clavicular head and coracoid, respectively.

METHODS:

Arteriovenous malformations (AVMs) are characterized by abnormal connections between arteries and veins which bypass the capillary system. Often small and asymptomatic, large AVMs can be painful, prone to bleeding and, if large enough, interfere with activities of daily living. While described involving various parts of the body, most notably in the central nervous system, there is a paucity of literature involving chest wall AVMs.

RESULTS:

Using a staged, multidisciplinary approach, treatment began with an endovascular exclusion of the arterial blood supply, which involved a combination of coil embolization and stent exclusion of feeder vessels. Two days postembolization, the patient underwent an en bloc resection of affected portion of his chest wall. Reconstruction was completed with a combination rotational flap and split-thickness skin graft. Following the procedures, the patient had an uncomplicated recovery. Three years following procedure, he has no signs of recurrence of his AV malformation.

CONCLUSION:

Surgical planning and indications for giant arteriovenous malformations remains a unique and difficult problem. The complex anatomy and extreme rarity of a chest wall AVM requires a multidisciplinary staged approach but can be treated with a multistage, multidisciplinary surgical approach with satisfactory and long-lasting results.
