Popliteal artery pseudoaneurysm of spontaneous occurrence: a case report

J Vasc Bras. 2024 Aug 23;23:e20240021. doi: 10.1590/1677-5449.202400212. eCollection 2024.

ABSTRACT

Idiopathic popliteal artery pseudoaneurysms are exceedingly rare, posing significant diagnostic challenges due to their elusive etiology. This report presents the case of a 78-year-old female with no history of trauma or orthopedic procedures who was diagnosed with a large pulsatile mass in the right popliteal fossa. Arteriography confirmed a popliteal artery pseudoaneurysm. Despite extensive clinical evaluation, no causative factors were identified, suggesting an idiopathic diagnosis. The patient underwent open surgical repair using a posterior approach, during which the popliteal artery defect was closed using a bovine pericardium patch. Postoperative follow-up revealed proximal patch stenosis, necessitating angioplasty. This case underscores the need for comprehensive diagnostic evaluation of atypical pseudoaneurysm presentations and highlights the complexities involved in managing idiopathic cases, emphasizing the importance of postoperative follow-up to address potential complications.

Innovative combined Ozaki and Bentall procedures for aortic root replacement

Multimed Man Cardiothorac Surg. 2024 Sep 11;2024. doi: 10.1510/mmcts.2024.038.

ABSTRACT

In treating aortic root diseases, the Bentall procedure offers reliable and stable results. However, it requires a prosthetic valved conduit, which presents inherent challenges due to the need for anticoagulation. The Ozaki procedure, which uses pericardium for aortic valve neocuspidization, is an alternative to prosthetic valves and does not need anticoagulation. We developed a surgical technique combining the Bentall and Ozaki procedures to treat patients with aortic root disease, which we describe in this article. Because the risk of bleeding due to anticoagulation after prosthetic valve replacement was a concern, we combined the Bentall and Ozaki procedures with a graft conduit using bovine pericardial patch neocuspidization. Postoperative echocardiography showed a competent aortic valve with no regurgitation. We believe that this novel procedure provides hope for a more adaptable and patient-friendly option.

Diagnostic utility of ultrasonography for thoracic and abdominal bacterial and parasitic diseases in ruminants: a comprehensive overview

Front Vet Sci. 2024 Sep 2;11:1435395. doi: 10.3389/fvets.2024.1435395. eCollection 2024.

ABSTRACT

This review article describes the roles of ultrasound in assessing thoracic and abdominal infectious diseases, mainly bacterial and parasitic ones that affect farm animals, including cattle, camels, sheep, and goats. Ultrasonography is a non-invasive imaging technique used to diagnose infectious diseases affecting the cardiovascular, respiratory, digestive, urinary, and hepatobiliary systems. In cases of thoracic and abdominal infections, ultrasound typically reveals abnormalities in echogenicity and echotexture, the presence of unusual artifacts, and mass formation exerting pressure on surrounding structures. Inflammatory and degenerative changes within the viscera can be identified ultrasonographically by comparing the echogenicity of affected areas with that of the surrounding normal parenchyma, such as in fascioliasis. Bacterial and parasitic infections often result in capsular mass lesions with anechoic contents, as observed in hydatid cysts and cysticercosis, or varying echogenic contents, as observed in liver abscesses. Effusions within the pericardium, pleura, and peritoneum are common ultrasonographic findings in infectious thoracic and abdominal diseases. However, these effusions’ echogenicity does not always allow for clear differentiation between transudates and exudates. The routine use of ultrasonography in the evaluation of the chest and abdomen in affected or suspected ruminants is highly beneficial for detection, guiding therapeutic decisions, assessing prognosis, and aiding in the eradication of highly contagious diseases that cause significant economic losses.
