| Summary: | This study aimed to assess the angiographic correlation between coronary artery
stenosis and internal iliac-internal pudendal artery (II-IPA) stenosis and
evaluate its association with erectile dysfunction (ED). We reviewed the data of
91 patients who had undergone pelvic angiography (PA) to evaluate II-IPA stenosis
and coronary angiography (CAG) due to suspected coronary artery disease. Erectile
function (EF) was evaluated using the International Index of Erectile Function
before CAG and PA. CAG was performed first, followed by PA of the bilateral
II-IPA. Regardless of the location and number of stenosis sites, based on CAG, we
categorized the patients into two groups. Patients with a maximum stenosis
<50% and ≥50% on CAG were assigned to Group I and Group II,
respectively. Then, the EF domain score and the diameter stenosis (DS) of II-IPA
were evaluated and compared. Overall, 55 patients comprised Group I, while 36
patients comprised Group II. ED was present in 96.3% and 97.2% of the patients
in Group I and II, respectively. There was no statistical difference between the
groups in the severity of ED (p = 0.457). PA revealed that 14.5% and
36.1% of patients in Groups I and II had ≥50% stenosis of the II-IPA.
The mean DS of II-IPA in Group II was greater than that in Group I (p =
0.017). There was a statistically significant correlation between the degree of
coronary artery stenosis and the degree of II-IPA stenosis (r = 0.295, p = 0.005). This study revealed that coronary artery stenosis correlates with
II-IPA stenosis. The presence and degree of coronary artery stenosis or II-IPA
stenosis indicate the necessity for more active treatment in patients with ED.
