A simple aid in advancing Dobbhoff tubes.

Using an angiographic guide wire, we found that the flexibility of the Dobbhoff tube could be overcome and, thus, manipulated under fluoroscopic control into the duodenum.

Cerebral angiographic changes associated with tuberous sclerosis.

Two patients with tuberous sclerosis were examined angiographically. In one, direct left carotid angiography showed a contralateral shift of the anterior cerebral artery and lateral displacement of the middle cerebral artery. On the lateral series, increase in the sweep of the anterior cerebral artery as well as stretching of the opercular branches of the middle cerebral artery were noted in the early arterial phase. In the later arterial phase, there was marked hypervascularity, with the contrast substance temporarily pooling in small, rounded collections. In the mid-arterial phase of the second case, pooling of the the contrast medium within the tumor and many small, berry-like outpunchings were noted. There was no evidence of early venous drainage in either case.

Traumatic vertebral artery pseudoaneurysm following chiropractic manipulation.

A vertebral artery pseudoaneurysm accompanied by serious neurological injury was seen in a 42-year-old woman who had undergone chiropractic manipulation of the neck. Such manipulation is a potential cause of neurological injury due to trauma to the cervical spine and the major vessels of the neck. The arterial pattern in this case was similar to that of angiodysplasia except for narrowing and irregularity of the vertebral artery.
