False Aneurysm of a Brachial Artery in a Very Premature Newborn

Abstract

The authors reported a case of false aneurysm in the lower third of the right brachial artery in a premature newborn (25 weeks of amenorrhea) subsequent to puncture performed 48 hours before. The treatment was surgical: resection of the false aneurysm and anastomosis (Monobrin 11-0 sutures) to restore the continuity of the brachial artery. After 6 months of follow-up, the course is favorable, with improvement in healing and absence of any functional disorder of the arm.

Percutaneous ultrasound guided thrombin injection for axillary artery pseudoaneurysm following stenting of the arterial duct in two infants: Case report with review of literature

“…Potential risk factors associated with pseudoaneurysm formation are anticoagulation, large sheath size, brief manual compression, simultaneous catheterization of artery and vein, sites that are difficult to compress and puncture of superior femoral artery. Most common cause for pseudoaneurysm in infants is iatrogenic . In our cases we chose to use 5Fr sheaths for guiding catheters to be advanced.…”

“…Failure rates are higher in ultrasound guided pseudoaneursym sac neck compression . Thrombin injection and surgical resection with end to end anastomosis or bypass graft have also been reported. However thrombin injection is less invasive compared to surgery especially in infants.…”

“…Most common cause for pseudoaneurysm in infants is iatrogenic. [5][6][7][8][9][10][11][12][13][14] In our cases we chose to use 5Fr sheaths for guiding catheters to be advanced. Smaller caliber short sheaths can be used as well, though it is unclear if that alone would have reduced the risk of pseudoaneurysm formation.…”

“…18,19 Failure rates are higher in ultrasound guided pseudoaneursym sac neck compression. 6,7,10 Thrombin injection 7,10 and surgical resection with end to end anastomosis 6,8,9,13,20 or bypass graft 11 have also been reported.…”
