BACKGROUND High flow priapism (HFP) is a rare type of priapism. Perineal trauma is the most common cause of HFP. Trauma-induced penile artery injury may lead to an arterial-cavernosal fistula, whereas persistent irregular arterial blood flow entering the corpora cavernosum can cause a persistent penile erection. The routine treatment of HFP focuses on addressing the abnormal penile erectile status and avoiding post-treatment erectile dysfunction. Interventional embolization is an important therapeutic modality for HFP, and bilateral embolization therapy is currently the most commonly used technique for patients with bilateral cavernous artery fistulas; however, unilateral embolization therapy has yet to be reported. CASE SUMMARY Herein, we report of the case of a 26-year-old Chinese male who presented with a persistent abnormal erection for 12 h after perineal impact injury. Medical history, cavernous arterial blood gas analysis and radiological examinations led to a diagnosis of HFP caused by bilateral cavernous artery fistulas. We performed routine conservative treatment (compression therapy and ice application) for the patient after admission; however, 10 d later, his symptoms had not been relieved. After completion of the preoperative workup, right (severe side) selective perineal artery embolization was performed; the left cavernous artery fistula was left untreated. After postoperative continuation of conservative treatment for 72 h, the patient experienced complete penile thinning. The patient had no symptoms of erectile dysfunction over a follow-up period of 12 mo. CONCLUSION Compared with bilateral cavernous artery fistula embolization, we believe that unilateral cavernous artery fistula embolization can achieve positive clinical efficacy and reduce the risk of postoperative erectile dysfunction secondary to penile ischemia.

“…With respect to identification of the number and origins of bronchial arteries, diagnostic confidence, and image quality, CBCT was superior to both pre-procedural CT ( p = 0.03) and flush DSA aortography ( p = 0.001). He and associates used selective CBCT in 26 arteries thought likely to supply the pathologic entity causing hemoptysis [ 13 ]. CBCT determined whether the targeted artery supplied the source of bleeding in 24 arteries (92%).…”

Purpose To describe the technique and document utility of adjunctive cone-beam CT (CBCT) in patients undergoing bronchial artery embolization (BAE) or chemoinfusion (BAC). Materials and Methods Between August 2010 and February 2021, 26 patients (62 bronchial arteries) were evaluated with CBCT in addition to the usual digital subtraction angiography (DSA) during BAE or BAC. 19 patients (43 arteries) underwent BAE for hemoptysis; 7 patients (19 arteries) had BAC for palliation of lung malignancy. Retrospective review of procedural reports and the archived DSA and CBCT images was assessed for (1) whether CBCT findings added unique diagnostic information prior to treatment of target arteries compared to DSA alone; and (2) whether these unique CBCT findings led to modification of embolization or chemoinfusion technique. Results In 61 of 62 (98%) interrogated bronchial arteries, CBCT provided additional unique diagnostic information over planar DSA, primarily cross-sectional assessment of the spinal canal for spinal arteries. In 46/62 (74%) of the bronchial arteries the unique information did not lead to a change in therapeutic technique. In 15 bronchial arteries (24%), the added information from CBCT led to change in embolization and/or chemoinfusion technique. Embolization of one small unrecognized spinal artery branch (1.6%), which was missed intra-procedurally but retrospectively seen on CBCT led to transient spinal cord ischemia. Conclusions These results suggest that adjunctive use of CBCT technique may improve diagnostic confidence from information provided by DSA in nearly all cases of BAE and BAC leading to improved therapeutic targeting or change in technique of embolization or chemoinfusion.
