Spinal cord injured (SCI) patients have sexual disorders including erectile dysfunction (ED), impotence, priapism, ejaculatory dysfunction and infertility. Treatments for erectile dysfunction include four steps. Step 1 involves smoking cessation, weight loss, and increasing physical activity. Step 2 is phosphodiesterase type 5 inhibitors (PDE5I) such as Sildenafil (Viagra), intracavernous injections of Papaverine or prostaglandins, and vacuum constriction devices. Step 3 is a penile prosthesis, and Step 4 is sacral neuromodulation (SNM). Priapism can be resolved spontaneously if there is no ischemia found on blood gas measurement or by Phenylephrine. For anejaculatory dysfunction, massage, vibrator, electrical stimulation and direct surgical biopsy can be used to obtain sperm which can then be used for intra-uterine or in-vitro fertilization. Infertility treatment in male SCI patients involves a combination of the above treatments for erectile and anejaculatory dysfunctions. The basic approach to and management of sexual dysfunction in female SCI patients are similar as for men but do not require treatment for erectile or ejaculatory problems.

Thromboembolism and atherosclerotic stenosis both can cause arterial occlusion. Aortoiliac occlusive disease involving bifurcation of the aortoiliac artery induces symptoms of ischemia such as claudication and pain of buttocks and thighs, decreased bilateral femoral pulses, and impotence. Here, we describe a 58-year-old woman with a past history of atrial fibrillation and lacuna stroke with minimal right side weakness. She presented to our emergency department with sudden onset bilateral pain in the legs and paraplegia. A comprehensive examination revealed paresthesia and decreasing bilateral distal pulses. Computed tomographic imaging showed filling defects over the low abdominal aorta just above the bifurcation of the common iliac artery and bilateral femoral arteries. Acute aortic embolic occlusion was suspected. Her symptoms were resolved after emergent thrombectomy for acute limb ischemia. Physicians need to be aware of aortoiliac embolic occlusive disease which may present as acute paraplegia.

Approximately 20%-40% of patients with abdominal aortic aneurysms can have unilateral or bilateral iliac artery aneurysms and/or ectasia. This influences and compromises the distal sealing zone during endovascular aneurysm repair. There are a few endovascular techniques that are used to treat these types of aneurysms, including intentional occlusion/over-stenting of the internal iliac artery on one or both sides, the "bell-bottom" technique, and the more recent method of using an iliac branch stent graft. In some cases, other options include the "snorkel and sandwich" technique and hybrid interventions. Pelvic ischemia, represented as buttock claudication, has been reported in 16%-55% of cases; this is followed by impotence, which has been described in 10%-17% of cases following internal iliac artery occlusion. The bell-bottom technique can be used for a common iliac artery up to 24 mm in diameter given that the largest diameter of the stent graft is 28 mm. There is a paucity of data and evidence regarding the "snorkel and sandwich" technique, which can be used in a few clinical scenarios. The hybrid intervention is comprised of a surgical operation, and is not purely endovascular. The newest branch stent graft technology enables preservation of the anterograde flow of important side branches. Technical success with the newest technique ranges from 85%-96.3%, and in some small series, technical success is 100%. Buttock claudication was reported in up to 4% of patients treated with a branch stent graft at 5-year follow-up. Mid- and short-term follow-up results showed branch patency of up to 88% during the 5-6-year period. Furthermore, branch graft occlusion is a potential complication, and it has been described to occur in 1.2%-11% of cases. Iliac branch stent graft placement represents a further development in endovascular medicine, and it has a high technical success rate without serious complications.

About 20% of patients with abdominal aortic aneurysms have associated iliac aneurysms. Distal sealing during the endovascular treatment of aortic-iliac aneurysms is a challenge that has led to the emergence of several technical options to achieve this goal over the years. Internal iliac artery embolization is associated with the risk of ischemic complications, such as gluteal necrosis, lower limb neurological deficit, colonic ischemia, impotence and gluteal claudication. This article summarizes the technical options for endovascular treatment of aortoiliac aneurysms with different approaches to preserving the patency of internal iliac arteries.

Leriche syndrome is a disease of aortoiliac occlusion, which causes diminished femoral pulses, impotence and claudication. As blood flow to the rectum is also decreased in Leriche syndrome, reconstruction with anastomosis may be complicated by ischemia when performing rectal cancer surgery. The inferior epigastric arteries often provide collateral circulation to the lower limbs in patients with Leriche syndrome, therefore, attention should be paid not to injure them during trocar insertion when performing laparoscopic surgeries. The present study is a report on three cases of patients with colorectal cancer who were successfully treated with laparoscopic surgeries. The first case was of a 71-year-old man with rectal cancer. A preoperative computed tomography (CT) scan revealed occlusion of the aorta below the origin of the inferior mesenteric artery. The blood flow to the lower limbs was supplied through collateral arteries, including the inferior epigastric arteries and the deep circumflex iliac arteries. A laparoscopic Hartmann's operation was performed successfully following marking of the inferior epigastric arteries using ultrasonography to avoid damaging them during trocar insertion. The second case involved a 70-year-old man with three colorectal cancers of the transverse and sigmoid colon and rectum. A CT scan revealed occlusion of the aorta below the origin of the renal arteries. Laparoscopic assisted low anterior resection and left hemicolectomy with colostomy were performed. The final patient was a 61-year-old man with rectal cancer. As the right internal iliac artery was patent, the patient underwent laparoscopic assisted low anterior resection. All the patients were discharged from the hospital without complications. It is important to visualize the image the blood flow via CT angiography and to mark collateral arteries using ultrasonography preoperatively in patients with Leriche syndrome for whom laparoscopic surgery was planned for to treat colorectal cancer.

Aortoiliac occlusive disease (AOD) is a rare presentation of thrombosis of the abdominal aorta. Also known as Leriche syndrome, its classic description entails claudication of the buttocks, thighs, and calves, absent femoral pulses, and impotence. AOD risk factors include smoking, hypertension, hyperlipidemia, diabetes, chronic renal insufficiency, and hypercoagulopathy. Ischemic complications of gastrointestinal malperfusion, renal infarction, and paralysis secondary to spinal cord ischemia are also noted. This case describes AOD complicated by a Stanford Type B aortic dissection leading to multi-system organ failure. A brief review of the literature further elucidates the key risk factors in identifying and treating Leriche syndrome.
