  		Fig. 1. —6-year-old girl with Volkmann's ischemic contracture who was evaluated for preoperative arterial changes. Upper extremity volume-rendered MDCT angiogram shows occlusion of distal brachial artery and reconstitution of ulnar and radial arteries, mainly by recurrent branch of deep brachial artery (short arrows) and small antecubital collaterals (long arrow).

  		Fig. 2. —9-year-old boy with suspected stenosis of ulnar artery who underwent prior ulnar artery transection repair. Volume-rendered MDCT angiogram of forearm in anterior projection shows wide patency of radial (short arrow), ulnar (long arrow), and interosseous (arrowhead) arteries. No stenosis is seen in repaired ulnar artery.

  		Fig. 3. —6-year-old girl with amniotic band–related congenital leg malformation. Volume-rendered MDCT angiogram in posterior projection shows wide patency of distal left popliteal artery and peroneal artery (arrow). Congenital band constricted peroneal artery distally, and no major artery was seen below constriction. Posterior tibial artery was congenitally atretic.

  		Fig. 4B. —Volume-rendered MDCT angiogram in 6-year-old boy with polydactyly who will undergo surgical excision of extra phalanx. Right anterior oblique projection shows that first digital artery (arrow), traversing from medial aspect of thumb, mainly supplies distal phalanx.

  		Fig. 5. —9-year-old boy with polyarteritis nodosa and thenar erythema who was suspected of having arterial occlusion. Volume-rendered MDCT angiogram in anterior projection shows bilateral patency of radial artery (short arrows), superficial palmar branch of radial artery (arrowheads), and ulnar (long arrows) and digital arteries with no evidence of occlusion. Superficial and deep palmar arches are also seen. Note venous contamination that does not obscure arterial structures.
