Below-the-Ankle Antegrade Teleferic Technique: New Approach for Below-the-Ankle Revascularization in Challenging Cases of Chronic Limb-Threatening Ischemia.

Purpose: To describe a novel bailout technique to approach below-the-ankle (BTA) chronic total occlusions or plantar-arch severe disease where the balloon/catheter is unable to follow the crossing guidewire and no other described recanalization approach is feasible.

Technique: When facing a complex BTA revascularization, if the guidewire crosses but the balloon cannot progress due to a lack of pushability, an antegrade puncture of the infrapopliteal vessel where the tip of the guidewire lays is performed. The guidewire is then carefully navigated through this distal BTA vessel into the needle to achieve its rendezvous and externalization.

Medical care for transgender individuals at a hospital in southern Brazil: why do they drop out from our service?

Objective: The objective of the study was to investigate dropout rates and discern potential factors contributing to the discontinuation of treatment provided to transgender individuals by the Transdisciplinary Gender Identity Program at the Hospital de Clínicas de Porto Alegre (PROTIG).

Methodology: This study employs a descriptive, cross-sectional, retrospective design to analyze socio-demographic and clinical data obtained from medical records of patients treated at PROTIG between 2000 and 2018. A structured form, devised by PROTIG's professional team, was utilized to extract and evaluate several variables including: age, gender, education level, diagnosis of F64 according to the International Classification of Diseases (ICD-10: Version: 2010), clinical comorbidities (coded by ICD-10), laboratory diagnosis of sexually transmitted infections, distance between patients' residence and the hospital, and year of entry into PROTIG.
