Positional priapism and scrotal swelling: An unusual presentation of IVC filter associated thrombosis and May-Thurner syndrome.

Scrotal edema and positional priapism are uncommon chief complaints with a scant differential. May-Thurner syndrome as well as inferior vena cava thrombosis are not often associated with these symptoms. This report outlines the case of a 50-year-old male who has undergone pulmonary artery thrombectomy and inferior vena cava filter placement. He presents with a chief complaint of scrotal swelling and positional priapism, likely low-flow priapism. Upon further work up, in-filter thrombosis was identified, likely attributed to a lack of anticoagulation and May-Thurner syndrome was diagnosed. The patient subsequently underwent thrombolysis and thrombectomy and was found to have May-Thurner syndrome which was treated with left iliac vein stenting.

Persistence of pulmonary hypertension in patients undergoing ventricular assist devices and orthotopic heart transplantation.

Pulmonary hypertension (PH) is common in advanced heart failure and often improves quickly after left ventricular assist device (VAD) implantation or orthotopic heart transplantation (OHT), but long-term effects and outcomes are not well-described. This study evaluated PH persistence after VAD as destination therapy (VAD-DT), bridge to transplant (VAD-OHT), or OHT-alone. The study constituted a retrospective review of patients who underwent VAD-DT (n = 164), VAD-OHT (n = 111), or OHT-alone (n = 138) at a single tertiary-care center. Right heart catheterization (RHC) data was collected pre-, post-intervention (VAD and/or OHT), and 1-year from final intervention (latest-RHC) to evaluate the longitudinal hemodynamic course of right ventricular function and pulmonary vasculature. PH (Group II and Group I) definitions were adapted from expert guidelines. All groups showed significant improvements in mean pulmonary artery pressure (mPAP), pulmonary artery wedge pressure (PAWP), cardiac output, and pulmonary vascular resistance (PVR) at each RHC with greatest improvement at post-intervention RHC (post-VAD or post-OHT). PH was reduced from 98% to 26% in VAD-OHT, 92%-49% in VAD-DT, and 76%-28% in OHT-alone from preintervention to latest-RHC. At latest-RHC mPAP remained elevated in all groups despite normalization of PAWP and PVR. VAD-supported patients exhibited suppressed pulmonary artery pulsatility index (PaPi < 3.7) with improvement only posttransplant at latest-RHC. Posttransplant patients with PH at latest-RHC (n = 60) exhibited lower survival (HR: 2.1 [95% CI: 1.3-3.4], p < 0.001). Despite an overall significant improvement in pulmonary pressures and PH proportion, a notable subset of patients exhibited PH post-intervention. Post-intervention PH was associated with lower posttransplant survival.
