Key result
Venous angioplasty or stenting is linked to a ~14 mmHg reduction in orthostatic blood pressure drop.
Why the study?
Venous outflow obstruction from jugular valvular dysfunction or left brachiocephalic vein compression was hypothesized to cause OH, and improving venous return via endovascular intervention could alleviate symptoms.
Does balloon angioplasty and/or stenting reduce supine-standing systolic blood pressure disparity in patients with medically refractory orthostatic hypotension and venous stenosis?

Does balloon angioplasty and/or stenting reduce supine-standing systolic blood pressure disparity in patients with medically refractory orthostatic hypotension and venous stenosis?
Venous angioplasty and stenting may reduce supine-standing systolic blood pressure disparity and alleviate symptoms in patients with medically refractory orthostatic hypotension and venous outflow obstruction.
Hypothesis-generating for venous obstruction in OH; requires prospective validation before any clinical consideration.
Background: Orthostatic hypotension (OH) is identified by a significant decrease in blood pressure upon standing from a seated or supine position. A reduction in systolic blood pressure of 20 mmHg within three minutes of standing meets the criteria for clinical diagnosis. We hypothesized that venous outflow obstruction from jugular valvular dysfunction or extrinsic compression of the left brachiocephalic vein may cause OH. Improving venous return and reducing venous congestion of the autonomic pathways through endovascular intervention could alleviate symptoms. Methods: This retrospective review included six male patients (aged 63–87) with medically refractory OH who underwent venograms revealing jugular, brachiocephalic, or subclavian vein stenosis. Patients were treated with balloon angioplasty and/or stenting. Blood pressure was measured in supine, seated, and standing positions before and immediately after the procedure, with multiple readings per position (total n = 117 for supine-standing comparisons). Statistical analysis used Welch’s t-test to compare pre- and post-procedural systolic blood pressure disparities. Results: The patients showed improved post-procedural blood pressure and reduced OH symptoms. The average supine-standing systolic disparity decreased from 38.68 mmHg preoperatively to 24.61 mmHg postoperatively (p = 0.024). The seated-standing disparity was insignificant, possibly due to autonomic compensation. Patients also reported relief from associated symptoms like headaches, tinnitus, and vertigo. Conclusions: These findings suggest venous outflow obstruction may contribute to OH, and venoplasty/stenting can mitigate symptoms, potentially reducing reliance on medications with adverse effects. Further studies should explore the role of Venous Outflow Obstruction Disorders in neurological conditions.

Arcot et al. (2025) conducted an observational in Orthostatic hypotension (n=6). Balloon angioplasty and/or stenting vs. Pre-procedural baseline was evaluated on Supine-standing systolic blood pressure disparity (p=0.024). Balloon angioplasty and/or stenting reduced the average supine-standing systolic blood pressure disparity from 38.68 mmHg to 24.61 mmHg in patients with orthostatic hypotension (p=0.024).
