Arc of Buhler: A lifesaving anatomic variation. A case report
Abstract The presence of malperfusion syndrome in cases of complicated acute type B aortic dissection is a negative predictive factor and urgent intervention is indicated. Anatomic variations, such as the Arc of Buhler, contribute anastomotic channels and can preserve the visceral blood supply. In this case report, we describe the overall management of a 54-year-old man who presented with a type B aortic dissection. Initially, conservative management was chosen, as indicated for an uncomplicated type B dissection, but the dissection deteriorated. Despite the fact that severe occlusion of the celiac artery was detected on C...

Use of carbon dioxide for therapeutic decision-making in endoleaks: a case report
We report the case of a 72-year-old man with an endoleak two years after endovascular aneurysm repair. Images suggested a type III endoleak, but this was not confirmed by contrast aortography. We proceeded with the investigation using aortography with carbon dioxide and observed a type IA endoleak. This was successfully treated by implantation of a proximal cuff. A review of the literature shows that the role of carbon dioxide in endoleak management is still unclear. We present a case in which carbon dioxide was essential to both diagnosis and therapeutic decision-making in a type IA endoleak.Resumo O tratamento endovascul...

Free-floating thrombus in lower limb deep veins and May-Thurner syndrome: case report
We present the case of a patient with extensive deep venous thrombosis affecting the iliofemoral-popliteal territory with a floating thrombus extending from the left common iliac vein to the inferior vena cava. Treatment was performed with fibrinolytic therapy delivered with a multiperforated catheter, supplemented with anticoagulation with heparin and daily control angiography. At the end of the treatment, a significant stenosis was identified in the left common iliac vein, and angioplasty was performed with stenting. (Source: Jornal Vascular Brasileiro)

Severe COVID-19: understanding the role of immunity, endothelium, and coagulation in clinical practice
Resumo O SARS-CoV-2 é o responsável pela pandemia da COVID-19. O sistema imunológico é fator determinante no combate à infecção viral e, quando atua equilibrada e eficientemente, a doença é autolimitada e benigna. Uma parcela significativa da população, porém, apresenta resposta imune exacerbada. Os indiví duos diabéticos, hipertensos, obesos e com doenças cardiovasculares, infectados pelo vírus, apresentam maior chance de progredir para formas graves. Essas doenças estão relacionadas a processos inflamatórios crônicos e disfunção endotelial. Os receptores do tipo Toll estão presentes nas cé lulas d...

Current treatment options for craniofacial hyperhidrosis
Abstract Hyperhidrosis (HH) is characterized by sweating exceeding the amount necessary to meet the thermal regulation and physiological needs of the body. Approximately 9.41% of individuals with HH have craniofacial hyperhidrosis (FH). The present study aims to review the most current data in the literature regarding craniofacial hyperhidrosis, including pathophysiology, diagnosis and clinical presentation, treatment options (clinical and surgical), and outcomes. VATS (videothoracoscopy sympathectomy) is considered the gold standard for definitive treatment of axillary or palmar hyperhidrosis. Recently, several studies ha...

Results of treatment of acute occlusions of limb arteries at a university hospital - retrospective study
Conclusion Treatment of AAO was primarily performed by thromboembolectomy with a Fogarty catheter, either alone or in combination with other treatments, achieving amputation and complication rates compatible with the best results in the literature and were progressively lower in less advanced Rutherford categories.

Leg ulcers in sickle cell disease patients
Resumo As úlceras de perna são as complicações cutâneas mais comuns em pacientes com anemia falciforme. Acometem principalmente indivíduos homozigotos e são lesões de difícil cicatrização e recidivantes, com impactos físicos, psicológicos e econômicos. Neste trabalho, discutimos a apresentação clínica, o diagnóstico, a fisiopatologia das úlceras falcêmicas e as suas implicações sobre a terapêutica.Abstract Leg ulcers are the most common cutaneous complication of sickle cell disease. These lesions occur mainly in homozygous forms, are slow to heal and often relapse, causing negative physical, emotion...

Arteriovenous anastomosis learning curve using low cost simulator
Conclusions It was found that the training model used was effective for increasing learning of this technique. It is believed that future studies with larger samples or a higher number of phases could demonstrate both reduced time and improved quality of the anastomoses performed with statisti cal significance.

Superselective renal artery embolization for treatment of urological hemorrhage after partial nephrectomy in a solitary kidney
We present a case of a 66-year-old woman who had a history of left nephrectomy for clear cell carcinoma seven years previously and now presented with a 6 cm tumor involving the solitary kidney. She underwent partial laparoscopic nephrectomy with removal of the tumor on the right kidney. In the immediate postoperative period she had important and persistent hematuria associated with tachycardia, hypotension, and lumbar pain. After showing signs of hemodynamic instability, she was taken to the catheter laboratory where selective angiography of the right kidney was performed. Superselective embolization with controlled releas...

Abnormalities of the hallux skin and nail in the course of very rare arteriovenous malformation
Abstract Arteriovenous malformations (AVMs) are usually found in the pelvic area and the brain. These vascular anomalies are rarely reported in the toes. AVMs in the toes may be asymptomatic, but can also cause atypical symptoms. Congenital AVMs can expand as patients age and manifest in adulthood. They may be provoked by injury. Acquired AVM might be caused by iatrogenic factors, venous or arterial catheterization, percutaneous invasive vascular procedures, surgery, or degenerative vascular disorders. An AVM can damage surrounding tissues and can cause destruction of skin, nails and bones. The course of the disease is oft...
