Anti-vascular endothelial growth factor for proliferative diabetic retinopathy.
CONCLUSIONS: There was very low or low quality evidence from RCTs for the efficacy and safety of anti-VEGF agents when used to treat PDR over and above current standard treatments. However, the results suggest that anti-VEGFs can reduce the risk of intraocular bleeding in people with PDR. Further carefully designed clinical trials should be able to improve this evidence.

Vascular Anomalies of Posterior Fossa and Their Implications
Abstract: Posterior fossa houses very vital and sensitive structures namely midbrain, pons, medulla, and cerebellum. These structures are irrigated by vertebral, posterior inferior cerebellar, anterior inferior cerebellar, and superior cerebellar arteries. Parts of brain located in posterior fossa control important parts of body so any variation pertaining to stenosis, atresia, hypoplasia, fenestration, agenesis, and duplication in the arteries supplying these parts alter the irrigation pattern culminating into various morbid and mortal neurologic disorders. Therefore, a sound understanding and thorough knowledge of poster...

Implication of Deep-Vascular-Layer Alteration Detected by Optical Coherence Tomography Angiography for the Pathogenesis of Diabetic Retinopathy
The aim of this narrative mini review is to analyze optical coherence tomography angiography (OCTA) parameters from reports that involved both superficial and deep vascular layers in patients with diabetes and to assess their relevance for the pathogenesis of diabetic retinopathy (DR). Papers published from January 2015 to August 2018 describing the use of OCTA in diabetes were identified and reviewed through a Medline/PubMed search. OCTA studies suggest that parameters are altered in patients with diabetes in all retinal vascular layers. From all included studies that evaluated both the superficial and the deep vascular l...

Endovascular management of massive pulmonary embolism with clot fragmentation and suction
This study describes our experience with two patients that had massive pulmonary embolism and were treated with percutaneous mechanical thrombectomy and reports on the mid-term results of this procedure. A 28-year-old man and a 70-year-old woman were diagnosed with deep venous thrombosis and massive pulmonary embolism. They first had lower limb edema followed by sudden onset of dyspnea. Their physical examination revealed edema, tachypnea, chest discomfort and jugular turgescence. Both needed to receive oxygen using a nasal cannula. Doppler ultrasound, echocardiography, and computed tomography angiography were used to esta...

Posttraumatic pseudoaneurysm of medial plantar artery in a child: treatment with percutaneous thrombin injection
Pseudoaneurysms of the medial plantar artery are rare. The authors describe a case of a pseudoaneurysm of the medial plantar artery of a child who had suffered a penetrating laceration injury. Diagnosis can be confirmed using Doppler ultrasound and magnetic resonance angiography. As an alternative to the conventional surgery technique, percutaneous Doppler ultrasound-guided thrombin injection is a safe and effective treatment.O pseudoaneurisma da artéria plantar medial é raro. Os autores relatam um caso de pseudoaneurisma da artéria plantar medial após lesão perfurocortante em criança. O diagnóstico pode ser confirm...

Embolization by micro navigation for treatment of persistent type 2 Endoleaks after endovascular abdominal aortic aneurysm repair
Conclusion: Treatment of type 2 endoleaks using embolization by micronavigation is an effective and safe method and should be considered as a treatment option for this complication after endovascular repair of abdominal aortic aneurysms. Contexto: O reparo endovascular se estabeleceu como uma modalidade segura e efetiva no tratamento do Aneurisma de Aorta Abdominal. Uma das principais complicações deste tipo de tratamento é o Vazamento ou Endoleak, sendo o do tipo 2 o mais frequente deles. Objetivo: Fazer uma breve revisão de literatura e avaliar a segurança e a efetividade da embolização por micronavegação para ...

Iliac vein compression syndrome: literature review
Iliac vein compression syndrome is a clinical condition in which the right common iliac artery extrinsically compresses the left common iliac vein. The syndrome predominantly affects young women between their 2nd and 4th decades of life. In view of the syndrome's potential complications, it should be recognized/diagnosed and treated in symptomatic patients before it causes irreversible damage to patients' venous systems. Noninvasive methods, such as venous color Doppler US are reasonable screening methods, but angiotomography and magnetic resonance angiography are more reliable diagnostic tools and the method of choice for...

Leiomyosarcoma of the great saphenous vein
A 56-year-old male patient presented with a complaint of two painful, hard, palpable nodules in the right lower limb. A Doppler ultrasound scan revealed the presence of nodules, likely to be neoplastic. Computed angiography showed two solid hypervascular nodules in the right great saphenous vein, fed by branches of the posterior tibial artery. Embolization of the nodules using surgical cyanoacrylate was performed, followed by an excisional biopsy. Anatomical pathology and immunohistochemical analysis identified the nodule as a high-grade leiomyosarcoma, characterized by ten mitotic figures per ten high-power fields, necros...

Gastrointestinal bleeding from vascular malformations: Is octreotide effective to rescue difficult-to-treat patients?
Publication date: Available online 29 August 2016 Source:Clinics and Research in Hepatology and Gastroenterology Author(s): Andrea Iannone, Mariabeatrice Principi, Michele Barone, Giuseppe Losurdo, Enzo Ierardi, Alfredo Di Leo Gastrointestinal vascular malformations are responsible for 2–8% of all cases of bleeding and 30–40% of all obscure hemorrhages, being the most frequent cause of occult bleeding in older people. The aim of this review was to provide an up-to-date report about the use of octreotide in bleeding from both hereditary and acquired vascular malformations of the gastrointestinal tract. A systematic lit...

Bilateral low origin of testicular artery: a case report
Abstract The testicular artery is frequently subjected to radiographic imaging techniques such as angiography for diagnosis and treatment of conditions like epididymitis, testicular torsion, tumor, hematoma, and hydrocele and in cases of undescended testis. Radiologists and surgeons should therefore be aware of testicular artery variants. Although there are numerous studies and case reports that mention testicular artery variants, this is probably the first case, reporting a bilateral low origin of the testicular artery and discussing its probable embryological etiology.Resumo A art éria testicular é frequentemente exami...

Endovascular treatment of pseudoaneurysms secondary to chronic pancreatitis: reports of two cases
This article describes two cases of pseudoaneurysm in patients with chronic alcoholic pancreatitis; one involving the splenic artery and the other the gastroduodenal artery, complicated by thoracic and abdominal bleeding respectively. Both were successfully treated, using minimally invasive endovascular methods to implant coils and stent-grafts.Resumo O pseudoaneurisma decorrente de pancreatite cr ônica consiste em complicação rara, porém com alta taxa de mortalidade. Está etiologicamente associado à pancreatite crônica, e seu diagnóstico é feito mais comumente após ruptura, manifestando-se através de sinais clÃ...

Spontaneous dissection of the renal artery: case report
Resumo A dissec ção espontânea da artéria renal é uma patologia rara que, na maioria dos casos, ocorre de forma idiopática. Em alguns casos, pode estar associada à presença de alterações arteriais prévias. Os sintomas geralmente são discretos e inespecÃficos, dificultando o diagnóstico. Os autores rel atam o caso de um paciente do sexo masculino, de 40 anos, com quadro de hipertensão arterial não controlada de inÃcio recente. Na investigação da etiologia da hipertensão arterial, o eco-Doppler de artérias renais revelou a presença de estenose (> 80%) no ter ço médio da artéria renal esquerda, e a...

Anterior tibial artery entrapment syndrome: case report
Resumo A claudica ção intermitente é uma queixa geralmente relacionada com oclusão arterial secundária a doença aterosclerótica. Entretanto, em pacientes jovens com queixa de claudicação, outras causas devem ser pesquisadas, como a sÃndrome do aprisionamento da artéria poplÃtea, sÃndrome compartimental c rônica, compressões ósseas e arterites. Os autores relatam o caso de um paciente com claudicação intermitente devido à compressão extrÃnseca da artéria tibial anterior pela membrana interóssea, diagnosticada através de angiorressonância durante manobras de dorsiflexão do pé. A paciente foi tratad...
