Background: Carotid body tumor (CBT) is a rare neoplasm that arises from the chemoreceptor cells located at the carotid bifurcation. Giant CBTs are extremely rare, with only 16 cases reported to date.
Case Summary: A 63-year-old male with an unremarkable medical history presented with a right-sided, giant, Shamblin III CBT.

Purpose: Monocyte chemoattractant protein-1 (MCP-1/CCL2) plays a key role for infiltration of monocytes/macrophages and studies have demonstrated that the MCP-1/C-C chemokine receptor 2 (CCR2) axis might be involved in the pathogenesis and progression of abdominal aortic aneurysms (AAA). Molecular imaging has shown potential for human clinical research studies. We evaluated the expression of CCR2 in patients with small AAA using single-photon emission computed tomography (SPECT) with the technetium-99m-6-hydrazinylnicotinoyl-C-C-chemokine receptor-2 ligand (Tc-HYNIC-CCR2-L).

PAD is a progressive condition with high rates of amputation and mortality due to ischemic damage and limited graft options. Traditional synthetic grafts often fail due to poor integration, while autologous grafts may be unsuitable for patients with compromised vascular health.

Background: Endovascular therapy with balloon percutaneous angioplasty (PTA) in the femoro-popliteal segment is frequently performed, however, long-term favorable outcomes and patency remain challenging, with restenosis rates reaching 60% post-standard balloon angioplasty. Drug-coated balloons (DCBs) have shown promise in improving these outcomes; Paclitaxel, used in DCBs, inhibits hyperplasia and smooth muscle cell proliferation, reducing restenosis; however, the optimal dose of Paclitaxel remains unclear, with high-dose (HD-DCB [>3 mg/mm]) and low-dose (LD-DCB [<2.0 mg/mm]) options available.
