Imaging criteria to predict Shamblin group in carotid body tumors - revisited.

Purpose: This study aims to compare the imaging findings of carotid body tumors on contrast-enhanced computed tomography (CT) with the intraoperative Shamblin grade and to evolve an imaging-based scoring system that can accurately predict the Shamblin grade.

Methods: Preoperative contrast-enhanced CT scans of 40 patients who underwent surgical excision of carotid body tumors in our institution between 2004 and 2017 were retrospectively reviewed. The angle of contact with the internal carotid artery (ICA), tumor volume, presence of peritumoral tuft of veins, loss of tumor adventitia interface and distance from the skull base were assessed and compared with the intraoperative Shamblin grades of the tumor.

Objective: To assess the safety and efficacy of computed tomography (CT)-guided percutaneous RFA of osteoid osteoma in pediatric population.

Role of penumbra mechanical thrombectomy device in acute dural sinus thrombosis.

Background: In dural venous sinus thrombosis (DVST), the mortality ranges 5-30%. Deep venous system involvement and septic dural sinus thrombosis have a higher mortality rate. In acute occlusion, collateral flow may not be established, which may result in significant edema and mass effect.

Role of endovascular embolization in treatment of acute bleeding complications in haemophilia patients.

Objective:: Bleeding complications either spontaneously or post-operatively are very common in patients with haemophilia. Sometimes these bleeding complications remain unresponsive despite being on high dose of clotting factor replacement. The aim was to assess the role of endovascular embolization in patients with haemophilia in (a) treating haemorrhagic complications due to local causes refractory to clotting factors substitution and (b) reducing intraoperative blood loss in elective pseudotumour surgery.

Outcomes of catheter-directed treatment of lower extremity deep vein thrombosis of patients presenting to a tertiary care hospital.

Background: Lower extremity deep vein thrombosis (DVT) is a common illness with an annual incidence of 1 per 1000 adults. The major long-term complication of DVT is post-thrombotic syndrome (PTS) which occurs in up to 60% of patients within 2 years of an episode of DVT.

Aims: We aim to evaluate the outcomes of catheter-directed treatment (CDT) for symptomatic acute or subacute lower extremity DVT.

Use of a vascular sheath for introduction of radiofrequency ablation probe during radiofrequency ablation of osteoid osteoma.

Radiofrequency ablation (RFA) has now become a preferred treatment option for osteoid osteoma. Accurate placement of RFA probe into the nidus of osteoid osteoma is important for good clinical outcome. Various methods and techniques have been described in the literature available.

Acute Portal Vein Thrombosis, No Longer a Contraindication for Transjugular Intrahepatic Porto-Systemic Shunt (TIPS) Insertion.

Portal vein thrombosis, once considered as a contraindication to transjugular intrahepatic porto-systemic shunt (TIPS) is now considered as an indication. We report a case with clinical and technical success in a patient with Budd Chiari syndrome and acute portal venous thrombosis. Though it is a well-established option, with the best of our knowledge, we could not find a report from India.

Endovascular treatment of isolated arterial pulmonary malinosculation.

We report the endovascular management of a series of four cases of isolated systemic supply to normal lung or isolated arterial pulmonary malinosculation of the left lung. In these cases, the basal segments of the left lung lacked normal pulmonary arterial supply and instead received systemic arterial blood from the descending thoracic aorta. The relevant anatomy and literature are also reviewed.
