Endovascular treatment of scalp cirsoid aneurysms.

Background: Scalp is the most common site of soft tissue arteriovenous fistulae and surgical excision has been the primary mode of treatment. Endovascular treatment has evolved as an alternative to the surgery. Aims: To evaluate the effectiveness of percutaneous direct-puncture embolization of cirsoid aneurysms. Materials and Methods: From January 1995 to December 2004, 15 patients underwent percutaneous direct-puncture embolization of cirsoid aneurysms. Plain X-ray, computerized tomography scan and complete selective cerebral angiogram were done in all. Seven patients had forehead lesions, four had temporal and the remaining four patients had occipital region cirsoid aneurysms. Lesions were punctured with 21-gauge needle and embolized with 20-50% cyanoacrylate-lipiodol mixture. Circumferential compression was applied during injection. Results: Post-embolization angiogram showed complete obliteration in 11 patients. The remaining four patients required adjunctive transarterial embolization with polyvinyl alcohol particles for complete lesion devascularization. Two patients had post procedure surgery for removal of disfiguring and hard glue cast. There were no major procedure-related complications. No patients had any recurrence in the follow-up. Conclusion: Percutaneous direct puncture embolization of cirsoid aneurysms is a safe and effective procedure. It can be effectively used as an alternative to surgery. Sometimes adjunctive transarterial embolization is also required to deal with deeper feeders.

Carotid artery stenting: results and long-term follow-up.

BACKGROUND AND PURPOSE: The role of carotid artery stenting (CAS) as an alternative to carotid endarterectomy in the treatment of for symptomatic carotid artery stenosis is investigated. MATERIALS AND METHODS: Forty-seven patients underwent CAS over 10-year period. Forty-nine vessels were treated. Stenosis quantification was done using North American symptomatic carotid endarterectomy trial method. The mean follow-up period by clinical and Duplex examination ranged is 5.6 years. RESULTS: The technical success rate was 100%. There were four deaths (8.1%) and two (4.1%) minor strokes within thirty days of procedure. There was no major strokes. All patients with minor stroke achieved complete recovery at 1-month follow up. Two deaths occurred probably due to hyperperfusion syndrome (HS) and two due to cardiac arrest. CONCLUSION: CAS is an effective treatment modality of symptomatic carotid artery disease but should be carefully done in high-risk groups having severe medical ailments and those having severe bilateral stenosis of the carotid arteries.

Percutaneous vertebroplasty in the management of vertebral lesions.

BACKGROUND: Debilitating backache due to different types of vertebral lesions is a common cause of morbidity in all age groups. Percutaneous vertebroplasty (PV) gives substantial pain relief and stabilizes the weak vertebrae. Most of the information regarding PV comes from the Western literature. The effect of PV in our population should be studied. AIMS: The primary objective is to assess the therapeutic benefit of PV in alleviating back pain and improving the functional status in patients with painful pathologic vertebrae. The secondary objectives are to study the technical aspects of the procedure and their relation to outcome and complications. SETTINGS AND DESIGN: This is a retrospective hospital-based (tertiary teaching hospital) study. MATERIALS AND METHODS: From January 2001 to December 2004, 46 patients underwent PV procedures. Sixty-five vertebroplasties were done in 13 males and 33 female patients. Twenty-four (36.92%) procedures were done for osteoporotic compression collapse, 26 (40.0%) for hemangioma, and 15 (23.07%) for different vertebral body tumors and metastasis. The Wilcoxon signed rank test was used to evaluate the statistical significance of differences between the preoperative and postoperative levels of pain, mobility and analgesic usage. RESULTS: Most of the patients had pain relief within 48 h. Only minor side effects were encountered. No patient had any deficit related to the procedure. On follow up of 3-48 months, all patients had statistically significant improvement in clinical condition (P < 0.001). CONCLUSION: Percutaneous vertebroplasty is a safe and effective procedure in relieving debilitating backache and can be used to treat vertebral lesions in selected cases.
