Recurrent lower limb venous insufficiency is often a challenge in clinical practice and is most commonly due to incompetent perforators. Many of these patients do not have adequate symptom relief with compression and require some form of treatment for incompetent perforator interruption. Various treatment methods have been tried with different efficiencies. Objective To evaluate the feasibility, efficiency and safety of an outpatient combined cyanoacrylate adhesion-sodium tetradecyl sulphate sclerotherapy for treatment of patients with symptoms of persistent or recurrent lower limb venous insufficiency secondary to incompetent perforators. Methods Eighty-three limbs of 69 patients with symptoms of persistent or recurrent lower limb venous insufficiency secondary to incompetent perforators were treated with cyanoacrylate embolization of incompetent perforators and sclerotherapy of dilated collateral veins (surface branch varicose veins). Technical success, procedural pain, perforator occlusion, venous occlusion, clinical improvement and ulcer healing were assessed. Follow-up was done three- and six-month post-procedure. Results Procedure could be successfully performed in all patients. One hundred and ninety-one perforators were treated in total. Perforator and varicose veins occlusion rate was 100%. Deep venous extension of cyanoacrylate occurred in four (4.8%) patients, with no adverse clinical outcome. Venous clinical severity score improved from a baseline of 8.18 ± 3.60 to 4.30 ± 2.48 on three-month follow-up and 2.42 ± 1.52 on six-month follow-up (p < 0.0001). All ulcers showed complete healing within three months. Significant prolonged thrombophlebitis occurred in 38.5% of limbs. Conclusion Combined cyanoacrylate adhesion and setrol sclerotherapy is technically easy, has a lot of advantages including being an outpatient procedure and highly efficacious but with a guarded safety profile.
Various treatment methods are available for the treatment of varicose veins, and there has been a recent surge in the usage of cyanoacrylate glue for treating varicose veins. Purpose To investigate the technical possibility, efficiency and safety of cyanoacrylate adhesive embolization and sclerotherapy using commonly available n-butyl cyanoacrylate glue for the treatment of primary varicose veins due to great saphenous vein reflux with or without incompetent perforators. Materials and Methods One hundred forty-five limbs of 124 patients with varicose veins due to great saphenous vein reflux were subjected to cyanoacrylate adhesive embolization and sclerotherapy - adhesive embolization of great saphenous vein in the thigh and perforators using cyanoacrylate followed by sclerotherapy of any residual varicose veins in the leg. Procedural success, venous closure rates and clinical improvement were assessed. Follow-up for 1, 3, 6, 9 and 12 months was obtained. Results Technical success rate was 100%. Saphenous vein closure rate was 96.5% at one year. There was no femoral venous extension of cyanoacrylate in any of the patients. Posterior tibial vein extension of cyanoacrylate was seen in three patients (2.6%) without untoward clinical effect.Significant improvement was found in venous clinical severity score (VCSS) from a baseline mean of 7.98 ± 4.42 to 4.74 ± 3, 1.36 ± 1.65 and 0.79 ± 1.19 at 1, 6 and 12 months' follow-up. Ulcer healing rate was 100%. Conclusion Cyanoacrylate adhesive embolization and sclerotherapy for the treatment of primary varicose veins is efficacious and can be performed as an outpatient procedure, but has a guarded safety profile due to its propensity to cause deep venous occlusion if not handled carefully.
There are a number of common pain disorders that can be managed effectively by injections around or ablation of peripheral nerves. Ultrasound is a universally available imaging tool, is safe, cost-effective, and is excellent in imaging many peripheral nerves and guiding needles to the site of the nerves. This article aims to present an overview of indications and techniques of such procedures that can be effectively performed by a radiologist.
In the adult population, foreign bodies may be accidentally or intentionally ingested or even inserted into a body cavity. The majority of accidentally ingested foreign bodies pass through the alimentary tract without any complications and rarely require intervention. Accidentally ingested foreign bodies are usually fish bones, bones of other animals, and dentures. Oesophageal food impaction is the commonest cause of oesophageal foreign bodies in the Western hemisphere. Intentionally ingested foreign bodies may be organic or inorganic, and often require intervention; these patients have either underlying psychological or mental disease or are involved in illegal activities such as body packing, which involves trafficking narcotics. Imaging plays a crucial role in not only identifying the type, number and location of the foreign body but also in excluding any complications. In this comprehensive pictorial review, we provide an overview of the spectrum of foreign bodies ingested in adults, emphasising the role of various imaging modalities, their limitations and common foreign body mimickers on imaging.
Background
Fish bones are the most common cause of accidental foreign body ingestion, especially in Asian and Mediterranean nations. In most cases, the fish bones pass through the alimentary tract without any complications and rarely require any intervention. Less than 5% of the patients with accidentally ingested fish bones develop complications. In this report, we present the first documented case of a fish bone induced bronchial artery pseudoaneurysm in an elderly male with underlying bronchiectasis; the latter recognized as a risk factor for developing bronchial artery hypertrophy.
Case presentation
We report a case of a fish bone induced bronchial artery pseudoaneurysm in a patient with underlying bronchiectasis. The vascular complication induced by the fish bone was identified only on intravenous contrast CT and would not have been identified on plain CT alone. The patient underwent bronchial artery embolization, following which the fish bone was dis-impacted endoscopically.
Conclusions
Intravenous post contrast chest CT may have an important role in the evaluation of accidental fish bone ingestion, especially in patients with underlying lung diseases, as vascular complications are most often overt on a non-contrast CT study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
