Acute thrombotic occlusion after total knee arthroplasty: Role of endovascular management.

Aim: Acute arterial occlusions after total knee arthroplasty (TKA) are rare but very serious complication. We present a series of 9 patients who underwent endovascular recanalisation for acute thrombotic occlusion following TKA in our institution. The present series determine the importance of early diagnosis and role of early intervention for good clinical outcome in these cases.

Imaging review of cerebrospinal fluid leaks.

Cerebrospinal fluid (CSF) leak occurs due to a defect in the dura and skull base. Trauma remains the most common cause of CSF leak; however, a significant number of cases are iatrogenic, and result from a complication of functional endoscopic sinus surgery (FESS). Early diagnosis of CSF leak is of paramount importance to prevent life-threatening complications such as brain abscess and meningitis.

Methods: From 2013 to 2016, a total of 39 patients (24 males and 15 females with a mean age of 64.5 years) underwent balloon angioplasty over a period of 2 years and 8 months in three different institutions in India.

Panvascular Disease in Familial Hypercholesterolaemia Treated with Endovascular Simultaneous Bilateral Carotid Stenting.

Familial Hypercholesterolaemia (FH) is a monogenic autosomal dominant disorder affecting 1 in 500 individuals. We report a case of 32-year-old female with FH, previously not on any treatment, who presented with recurrent bilateral Middle Cerebral Artery (MCA) territory strokes and dyspnoea on exertion due to severe panvascualar disease involving descending aorta, innominate, subclavian, common carotid, internal carotid and coronary vessels. Her complete clinical work up was done and was started on lipid lowering drug treatment and low calorie diet.

Local Intrasinus Thrombolysis for Cerebral Venous Sinus Thrombosis.

Background: Cerebral venous strokes due to cerebral venous sinus thrombosis (CVST) have varied presentation and clinical outcome. Despite aggressive medical treatment with optimal anticoagulation, some patients develop progressive neurologic deterioration causing significant morbidity and mortality. The aim of the present series is to analyze the safety and efficacy of thrombolysis in patients with cerebral venous sinus thrombosis in severe clinical grade and refractory to conventional medical management.

Congenital Absence of Internal Carotid Artery with Rare Type of Intercavernous Anastamosis and Ruptured Cerebral Aneurysm.

Congenital absence of Internal Carotid Artery (ICA) is a rare anomaly seen in <0.01% of the population. Various collateral circulations develop in these cases to maintain adequate cerebral perfusion.

Endovascular treatment of frontopolar artery aneurysm.

Traumatic intracranial aneurysms are rare and usually present with subarachnoid hemorrhage, intracranial hemorrhage, subdural hematoma, or intraventricular hemorrhage. These are usually not true aneurysms; hence treatment of these cases poses a therapeutic challenge. In this case report, we describe a young Asian male who presented with a ruptured pseudoaneurysm of the distal branch of the anterior cerebral artery.

Intracranial Pial Arteriovenous Fistulae: Diagnosis and Treatment Techniques in Pediatric Patients with Review of Literature.

Pial arteriovenous fistulae (AVF) are rare vascular lesions comprising single or multiple arterial feeders draining directly into the venous channel without intervening tangle of blood vessels as in brain AV malformations. In our present paper, we describe three cases of pial AVF in the pediatric age group with different presentations treated successfully with endovascular and surgical methods. Two patients underwent treatment for pial AVF by the endovascular technique and one by surgical clipping.

Endovascular treatment of fusiform A2 aneurysm with parent artery occlusion.

Background: A2 aneurysms are rare with a reported incidence of <1% of the intracranial aneurysms. These aneurysms are located between the anterior communicating artery and genu of the corpus callosum. Fusiform aneurysms in this location are even rarer and we present one such case of fusiform A2 aneurysm treated with endovascular technique.

Role of CT Imaging with Volume Reconstruction in Hemi Facial Hypertrophy: A Pediatric Case Report.

Hemifacial hypertrophy is a rare congenital disorder more common in males.It involves the soft tissue, hard bones and teeth of the face.Its etiology is unknown and multiple theories have been postulated.

Endovascular coil occlusion of traumatic intradural aneurysm with presentation as carotid cavernous fistula.

Carotid cavernous fistulae (CCF) are abnormal communication between cavernous segment of the internal carotid artery and cavernous sinus. These entities are usually encountered in 0.2-0.

Subdural B cell lymphoma. Imaging features, histopathology. Literature review.

Dural-based B cell lymphomas are rare and have a female preponderance. A 60-year-old Asian man with a history of trivial trauma presented with generalised tonic clonic seizures and headache. Imaging and clinical work-up was done.

Role of balloon-expandable stents in intracranial atherosclerotic disease in a series of 182 patients.

Background And Purpose: To demonstrate the safety and efficacy of balloon-expandable intracranial stents in patients with intracranial atherosclerotic lesions (>70% stenosis) who were symptomatic despite being on optimum medical therapy.

Methods: Between April 2004 and May 2012, 182 patients underwent intracranial stenting in our institution. All patients had symptoms despite being on optimum medical therapy.

Simultaneous bilateral carotid stenting in a series of 9 patients: a single-center experience with review of literature.

Objectives: Simultaneous bilateral carotid artery stenting (SBCAS) is a challenging procedure, and selection criteria play an important role in determining the final outcome. The aim of the present study was to determine the efficacy and safety of the SBCAS in a series of 9 patients with significant bilateral carotid artery disease (>50% on the symptomatic side and >60% on the asymptomatic side).

Materials And Methods: The present study is a retrospective study of 9 patients from January 2005 to December 2012 in a tertiary care center.

Spontaneous thrombosis of basilar tip aneurysm: Role of neuroimaging and follow-up with review of literature.

The incidence of pediatric aneurysms is rare compared to that of the adults. The natural history and the course of these aneurysms were not well understood. We present a rare case of spontaneously thrombosed basillar tip nongiant aneurysm in a 9-year-old male child who presented with symptoms of mass effect and subsequently followed up by imaging over a period of 1 year.

Background: To evaluate the safety and efficacy of stent-assisted coiling of ruptured intracranial wide-necked aneurysms in a setting of acute subarachnoid hemorrhage, without compromising on the antiplatelet regimen.

Methods: Forty-two consecutive patients who underwent stent-assisted coiling for ruptured wide-necked intracranial aneurysms from August 2008 to May 2012 were studied. Demographic data like age, sex, Hunt & Hess grade, Fischer scale, and location, and size of the aneurysms were noted.

Endovascular management of fusiform superior cerebellar artery aneurysms: a series of three cases with review of literature.

Distal superior cerebellar artery (SCA) aneurysms are rare. Fusiform aneurysms of SCA are rarer and more challenging to treat. Parent artery occlusion by endovascular coiling is the treatment option for these cases.

Idiopathic thrombus in the common carotid artery on digital subtraction angiography.

In the present study, we discuss the accuracy of digital subtraction angiography (DSA) in diagnosis of thrombus in the common carotid artery and its role in the medical management of this disorder. Between 2006 and 2011, four patients (age group ranging from 26 to 48 years) presented to our institution with symptoms of stroke. DSA in all these patients showed cigar-shaped filling defect in the common carotid artery.

Endovascular management of vein of galen aneurysm malformation: A series of two case reports.

Vein of Galen Aneurysm malformation is one of the most difficult intracranial vascular lesions to manage. The difficulty in management of its shunts is aggravated by the hemodynamic effect and shunting reflected in the growing brain of infants and children. At present, the therapeutic options are widened by the opening of a new horizon in Intervention Neuroradiology.
