Management of brachial artery aneurisms in infants

Abstract

Brachial artery aneurisms in children under 1 year of age are very rare. The main risk is distal ischaemic complication. We report four infants suffering from brachial artery aneurism of unknown origin. In all cases we used Doppler ultrasonography to validate the clinical diagnosis. Pre-operative vascular check-up was negative for other aneurismal location. Surgical excision with direct end-to-end anastomosis was possible in one patient; the others required interposition of an autologous venous graft. At discharge, patients were given oral aspirin for a few weeks. Histological examination revealed one pseudoaneurism and three true aneurisms. There were no complications either postoperatively or at 18 months follow-up. Arterial ligation might be indicated in only two situations: aneurism distal to profunda brachii artery, or chronic wall thrombus completely occluding (but distal perfusion through a neovascularization must be assessed first on angiography). Surgical excision with arterial reconstruction is the standard treatment. Endovascular treatment is not suitable because such a procedure in an infant would generate excessive radiation exposure, and a risk of stent migration with limb growth. In the case of an initial isolated and idiopathic presentation, or of false aneurism, clinical follow-up at 1 year is sufficient. In the case of secondary lesion, multiple initial presentation or relapse, life-long follow-up with repeated corporal imaging should be performed.

Radial artery pseudoaneurysm: A rare complication after a single arterial puncture for blood-gas analysis

“…Traditionally, arterial PAs are managed in various ways: observation, compression bandages, ultrasound-guided compression, ultrasound-guided thrombin injection, and surgical repair [ Table 2 ]. [ 6 7 8 ]…”

Delayed rupture of a pseudoaneurysm in the brachial artery of a burn reconstruction patient

“…Although a single small pseudoaneurysm that is located distal to the brachial bifurcation can be ligated [25], surgical excision with arterial reconstruction is the standard treatment. The arterial continuity should be restored with end-to-end anastomosis or a venous interposition graft [20,27]. Endovascular stent-grafts implantation is a minimally invasive intervention with a high success rate.…”

Pseudoaneurysm of the facial artery occurred after mandibular sagittal split ramus osteotomy

“…Although angiographic embolization is quite reliable and safe method, neurological complication or soft tissue necrosis related with destruction of existing vascular lesion or reflux of embolization material had been reported [22, 23]. The last option of treating the pseudoaneurysm is the surgical exploration and the removal of the lesion, especially when the lesion is located superficially and directly accessible [3] or the excessive radiation exposure is discouraged in growing children [24]. Therefore, we suggest pathway of the management for pseudoaneurysm as follows; interventional radiology as the first-line treatment and surgical approach as secondary option especially for the aforementioned indications.…”
