Purpose: When standard aortofemoral surgical procedure is combined with lower extremity vascular surgery, problems related with the hospital stay, morbidity, mortality and the cost of treatment will exist. The number of reports relating to combined iliac artery PTA and distal bypass surgery is limited. After the development of stenting procedures, the results of arterial system plasty have much more improved. This report reviews our preliminary experience with iliac artery angioplasty with distal bypass procedures.
Patients And Methods: A total of 41 patients have undergone combined iliac artery dilatation and distal arterial revascularization. Angioplastic procedures were performed in the angiography suite and distal surgery was carried out at the same day or the day after. Of all patients, 29 underwent percutaneous transluminal angioplasty (PTA) and 12 underwent combined PTA and stent placement. Ipsilateral femoropopliteal bypass was performed as a distal revascularization procedure in all patients.
Results: Mean systolic iliac artery pressure gradients improved from 34.7+/-8.6 mmHg to 3.9+/-3.2 mmHg after angioplastic procedures (P < 0.0001). Six patients needed reangioplasty because of restenosis in the follow-up period. Thrombectomy was performed on 1 patient in the early postoperative period and re-do femoropopliteal bypass was performed on two patients in the 2nd and 23rd months. Three minor wound infections were successfully treated with antibiotics and local care. Mean follow-up was 21.4 months (range 1-48 months). By life-table analyses, the overall 4-year cumulative primary patency of combined procedures was 78.1%.
Conclusion: The results show that the combined procedure is a suitable method for the treatment of patients with multiple stenotic lesions at the iliac and distal arterial levels. We believe that the combined use of PTA and distal vascular surgery by an experienced surgical team will give beneficial results and a highly satisfactory outcome in this group of patients.

We report a case of a 75-year-old man diagnosed with Parkes-Weber syndrome with an infected common femoral artery aneurysm secondary to chronic venous ulcers and groin infection. Given the symptomatic and rapid enlargement of the aneurysm, emergency aneurysmectomy and crossover femoro-femoral bypass were performed with an omental flap routed intraluminally through the aneurysm of the ipsilateral external iliac artery. The transarterial route enabled the short-cutting of the omental flap and the potential prevention of infection in the adjacent external iliac artery.

Multiple Aneurysmal Arterial Disease (MAD) is an extremely rare arterial vascular condition and is produced by an abnormal alteration of smooth muscle cells and neutrophils, producing a multiple-aneurysmal degeneration. We present the case of a 36-year-old patient with a MAD in the cerebral territory and extremities with no surgical indication; however, with an aneurysm of the right inferior renal segmental artery, inferior mesenteric artery, left common iliac artery, and right internal iliac artery with surgical indication. An open approach with single-stage surgical repair, including graft interposition, bypass, exclusion, and vascular reimplantation, was performed.

Lateral lymph node dissection (LLND) is getting global attention as an a surgical option to reduce local recurrence in locally advanced rectal cancer. As the transanal total mesorectal excision (TaTME) is gaining popularity worldwide, a novel LLND approach was established adopting a two-team approach that combines the transabdominal and transanal approaches using the TaTME technique. This narrative review describes the advantages, anatomical landmarks, surgical techniques, and pitfalls of transanal LLND (TaLLND).

Background: Cesarean hysterectomy in the placenta accreta spectrum (PAS) remains challenging due to difficulty in controlling perioperative bleeding.
Purpose: To compare the effectiveness and safety of perioperative balloon occlusion with versus without pelvic artery embolization in PAS women who underwent a cesarean hysterectomy.
Material And Methods: A total of 26 pathological confirmed cases of PAS were retrospectively reviewed and categorized into two groups: perioperative balloon occlusion at either the anterior division of the internal iliac artery or uterine artery followed by gelfoam embolization (n = 12, study group) and perioperative balloon occlusion alone (n = 14, control group).

The increasing age of patients with end-stage renal disease raises the issue of hostile arterial access for transplantation, with technical difficulties associated with clamping and suturing the iliac artery. Some of these patients - who theoretically represent those who would benefit the most from transplantation in terms of mortality - are contraindicated because of anatomical and medical issues. In this context, a specific endovascular device called EndoPreKiT (Endovascular Preparation for Kidney Transplantation) has been designed, enabling arterial access for transplantation via a mini-invasive procedure.
