From: Arterio-arterial malformation between a high origin radial artery and brachial artery within the cubital fossa - its clinical and embryological significance: a case report

Figure 4

Pathway 1 depicts the possible correct process of intussusceptive angiogenesis occurring in large vessels during embryological development. As the pillars form and coalesce at the bifurcation points, the vessel splits from one vessel into two new vessels (A, B). Pathway 2 depicts the failed process of intussusceptive angiogenesis that may have caused the arterio-arterial malformation. Rather than the distal and proximal bifurcations meeting and separating arteries A from B, the bifurcation points moved in opposite directions which may have caused the intussusceptive angiogenesis process to be halted.
