Purpose: One subset of peripheral arterial disease is aortoiliac occlusive diseases (AIOD). AIOD is the term for all arterial lesions between the infrarenal distal aorta and common femoral artery. Implantation of kissing stents (KS) with covered stents (CS), bare-metal stents (BMS) is one of the endovascular treatment (ET) modalities for AIOD involving aortic bifurcation. In this study, we report the outcomes of the KS technique in infrarenal AIOD.
Methods: Between January 2014 and September 2017, 31 patients who underwent ET were treated with KS technique either with balloon-expandable BMS or balloon-expandable CS. Technical details, clinical success, complications, and patency at follow-up were documented.
Results: The majority of patients were male (77.4%), and the median age was 62 years (range, 45-78 years). All patients were classified according to the TASC II criteria. Eight patients (25.8%) were classified as TASC B. Fifteen patients (48.4%) were classified as TASC C, and 8 patients (25.8%) were classified as TASC D. These 23 patients were classified as complex AIOD group. BMS was used in 17 patients (54.8%), and CS was used in 14 patients (45.2%). Technical and clinical success was achieved in 100% of treated cases. The median follow-up was 24 months (range, 24-34 months). Primary patency rates at 12, 18, and 24 months after ET were 100%, 96.8%, and 90.3%, respectively.
Conclusion: We found that the KS technique has satisfying 24-month results, even in complex AIOD lesions, with high technical success and acceptable midterm patency. Key Words: Aorta, Arterial occlusive diseases, Endovascular procedures, Iliac artery, Stents.

With their close anatomical relationship, the temporomandibular joint (TMJ), mandibular ramus, skull base, ear, and infratemporal fossa make up a complex structure that may collectively be referred to as the 'TMJ and adjacent structures complex' (TASC). This study presents the neoplasms that may be encountered in the TASC region and their classification, which may be useful for the surgical treatment. Data of 1022 consecutive patients treated with resection of TASC neoplasms from May 2000 to October 2022 were reviewed.

Article Synopsis
- - The study investigates whether using an endovascular approach, with or without common femoral endarterectomy (CFE), is safe and effective for treating patients with intermittent claudication due to complex aortoiliac occlusive disease (AIOD).
- - A review of 245 limbs from 180 patients treated from 2010 to 2020 showed low complication rates, with most patients showing improved Rutherford classification and favorable patency rates at 1, 2, and 5 years.
- - While patients undergoing CFE had more health issues and complex disease, the study found no significant differences in outcomes between those receiving only endovascular treatment and those who had combined procedures, indicating both approaches could be effective.

Background: This study investigated the midterm primary patency of drug-coated balloons (DCBs), directional atherectomy plus balloon angioplasty (DA), and bare metal stent (BMS) angioplasty for the treatment of femoropopliteal lesions.
Methods: This two-center retrospective cohort study included 105 patients (110 limbs) undergoing DCB, DA, and BMS angioplasty-32 patients (34 limbs), 31 patients (32 limbs), and 42 patients (44 limbs), respectively. The demographic, baseline, and procedure data were collected, and the complications and midterm outcomes (patency, amputation-free survival, and clinically driven target lesion revascularization rates) were analyzed.

Objectives: The modified Glasgow Prognostic Score (mGPS) is one type of inflammation-based index; it includes data on elevated C-reactive protein and reduced albumin content. The predictive value of mGPS for outcomes is investigated in various diseases such as cancer, heart failure, myocardial infarction, acute pulmonary embolism, and inflammatory bowel diseases. This study aimed to evaluate the link between mGPS and the severity and complexity of peripheral arterial disease (PAD) as determined by the Transatlantic Intercommunal Consensus Document (TASC-II) classification and the prediction value of mGPS for procedural success in patients undergoing endovascular treatment (EVT).

Background: Reports of large series of hybrid iliofemoral revascularization for chronic lower limb ischemia are scarce. The aims of this study were to evaluate outcomes for staged and nonstaged procedures, and to evaluate risk factors for outcomes at 90 days.
Methods: Patients were consecutively included between 2013 and 2023.
