AI Article Synopsis
- Venous hypertension in dialysis access is often caused by outflow obstruction, and the bidirectional proximal radial artery arteriovenous fistula (PRAVF) is rarely associated with this issue.
- A reported case highlights that a proximal occlusion in the medial cephalic vein resulted in peripheral venous hypertension due to altered blood flow.
- The text discusses this complication and its management considerations related to the creation of the bidirectional PRAVF.
Article Abstract
Venous hypertension due to dialysis access is usually secondary to outflow obstruction. The bidirectional proximal radial artery arteriovenous fistula (PRAVF) has been proposed as a procedure to increase autogenous fistula utilization and is rarely reported to cause peripheral venous hypertension. We report here a case of peripheral venous hypertension from a PRAVF, the first report to our knowledge caused by a peripheral outflow obstruction. A proximal occlusion in the medial cephalic vein led to retrograde flow through the median antebrachial vein into the hand. We briefly discuss this complication and considerations of its management in relation to the bidirectional PRAVF creation.

Hyperpolarized Xe MRI/MRS enables quantitative mapping of function in lung airspaces, membrane tissue, and red blood cells (RBCs) within the pulmonary capillaries. The RBC signal also exhibits cardiogenic oscillations that are reduced in pre-capillary pulmonary hypertension (PH). This effect is obscured in patients with concomitant defects in transfer from airspaces to RBCs, which increase RBC oscillation amplitudes.

Diagnosing ILD-PH is challenging due to the limitations of imaging methods. Right heart catheterization (RHC) is the gold standard for diagnosing PH but is limited to ILD patients considered for lung transplantation.

Background: Brachiocephalic fistula (BCF) and brachiobasilic fistula (BBF) are autogenous fistulas created in the arm for hemodialysis access. However, despite the differences in anatomy and surgical technique, the existing literature shows no significant statistical difference between the maturation, patency, or complications. We analyzed the outcomes of these two types of arteriovenous fistulas in our subgroup of the Indian population.

May-Thurner syndrome is an anatomical anomaly characterized by venous compression of the iliac vein by the arterial system. It is more common in women. It may be asymptomatic or lead to symptoms related to hypertension/venous occlusion, namely, edema of the lower limb.
