CT pulmonary angiography findings in HIV-infected patients referred for suspected pulmonary thrombo-embolic disease.

Background: South Africa bares a significant burden of HIV and imaging is commonly performed as part of the workup for respiratory distress.

Objectives: The aim of this study was to document the prevalence of pulmonary thrombo-embolic disease (PTED) and other findings in HIV-infected patients referred for CT pulmonary angiography (CTPA) for suspected PTED.

Method: Forty CTPA studies of documented HIV-infected individuals investigated for suspected PTED during a 1-year period were retrieved, anonymised and interpreted by three consultant radiologists.

Endovascular treatment of ophthalmic artery aneurysms: ophthalmic artery patency following flow diversion versus coil embolization.

Background And Purpose: The Pipeline Embolization Device (PED) has been shown to effectively treat complex internal carotid artery aneurysms while maintaining patency of covered side branches. The purpose of this retrospective matched cohort study is to evaluate the effect of flow diversion on the patency of the ophthalmic artery when treating ophthalmic artery aneurysms.

Methods: A retrospective review of our prospectively collected institutional database identified 19 ophthalmic artery aneurysms treated with a PED.

Vitamin D deficiency: appropriate replenishment therapies and the effects of vitamin D toxicity.
