Case Reports
Acute thrombosis and recanalization of a ruptured anterior communicating artery aneurysm.
A 35-year-old man sustained a subarachnoid hemorrhage due to the rupture of an anterior communicating artery aneurysm. A second angiogram taken 8 hours later demonstrated that the ruptured aneurysm had thrombosed spontaneously with a small residual aneurysm stump at the neck. ⋯ This case differs from previous reports of spontaneously thrombosed ruptured aneurysms because the aneurysm recanalized within 2 days. Thus a thrombosed ruptured aneurysm has the potential for recanalization, and should be considered at risk of further hemorrhage.

The human sacrum is the target of lumbosacral instrumentation and decompression procedures. Such surgical interventions require detailed knowledge of the anatomy of the human sacrum. The aim of this study was to measure surgically relevant parameters. ⋯ Thus, this study describes anatomical specifications of the sacrum. These defined morphometric details should be taken into consideration during surgical procedures. This study also describes anatomical landmarks which will allow injury of the sacrum during surgery to be avoided.

Various clinical signs have been used for assessing difficult intubation in patients with acromegaly. These signs include the modified Mallampati classification, measurement of thyromental distance and head and neck movements. Some authors have also tried to establish a relationship between growth hormone levels and difficult intubation. ⋯ The incidence of Mallampati III and IV grades was higher in patients with acromegaly. Increased thyromental distance was noted in patients with a long duration of disease. However, increased thyromental distance was not associated with difficult laryngoscopy.
