Role of interventional radiology in obstetrics and gynaecology: a clinical review of an experience in a quaternary care centre.

OBJECTIVE: The study aims to equip both Obstetricians and Gynaecologists with the knowledge of clinical conditions that will benefit from interventional radiology, equipment and materials that are commonly used, benefits, complications and the side effects of these techniques. METHODS: It was a single-centre, retrospective cohort study with examples from hospital practice during the period of 2015 to 2021, acquired through computerised database including all obstetrics and gynecological cases in which interventional radiology techniques were used. No statistical analysis of data was applicable as it was a single-centre retrospective analysis of cases. RESULTS: We had a total of 35 cases, including but not limited to placenta accreta spectrum disorders, fibroid, pelvic congestion syndrome and arteriovenous malformation who underwent various interventional radiological procedures ranging from embolization of uterine artery, peripheral angiography, embolization, and internal iliac artery balloon placement to ovarian vein embolization and coil insertion. CONCLUSION: Increased collaborative efforts between interventional radiology and gynaecology would allow patients to be fully informed on the complete spectrum of surgical and nonsurgical treatment options available to them.

Early migration of a self expanding intracranial stent: case report.

OBJECTIVE: With the development of support devices such as stents, an increasing number of aneurysms are meeting the criteria for endovascular treatment. A range of intracranial stents currently are available with an array of characteristics. It is essential to understand the properties of these stents to determine their role and implications in endovascular treatment of cerebral aneurysms. CLINICAL PRESENTATION: A 45-year-old man presented to our institution with subarachnoid hemorrhage secondary to a small distal basilar trunk aneurysm. INTERVENTION: An Enterprise stent (4.5 x 14 mm) was deployed in the parent vessel across the neck of the aneurysm. Repeat angiography 2 days later demonstrated significant proximal stent migration. A second, longer overlapping Enterprise stent (4.5 x 22 mm) was deployed from the left P1 segment into the basilar artery. Complete occlusion of the basilar trunk aneurysm was noted on subsequent angiography. CONCLUSION: This is an unequivocal case of early spontaneous migration of a self-expanding intracranial stent. We suggest caution when there is significant discrepancy in luminal diameter and suboptimal wall apposition. Early imaging following stent deployment may be indicated in these cases.
