Background: To report one the most feared complication of thoracic endovascular aneurysm repair (TEVAR); a retrograde aortic dissection who can involve the aortic arch or ascending aorta, which require commonly coextensive open surgical repair.
Case Reports: We report 2 cases of combined retrograde and antegrade dissection after endovascular treatment of an aneurysm of the descending aorta. In both cases, a dissection was identified at short-term follow-up; which required open surgical repair in one case and an additional endovascular treatment for the second case.
Conclusions: The incidence of extensive iatrogenic dissection after TEVAR is relatively low, open repair should be considered as a primary option in some cases with limited aortic dilatation to avoid such life-threatening complications.

We present the case of a 74-year-old female patient with a 50 mm ascending aortic aneurysm who underwent ascending aorta replacement. During routine open heart surgery, suboptimal flow in the cardiopulmonary bypass circuit, led to the discovery of a type B aortic dissection with substantial flow in the false lumen. Conservative management was chosen, focusing on blood pressure control in the ICU.

Background: The expanding number of parotid ablations, reconstructive and aesthetic surgeries of the head and neck, considerably increased the risk of the marginal mandibular branch (MMB) injury. The purpose of our study was to determine the anatomical peculiarities of the MMB depending on the facial nerve branching pattern (FNBP), gender and cephalometric type.
Materials And Methods: The MMB was dissected on 75 hemiheads of adult embalmed cadavers.

Introduction: Duplication of the gallbladder is a rare congenital malformation associated with the development of cholelithiasis. It increases the risk of iatrogenic bile duct injury during cholecystectomy and can lead to symptom recurrence if missed. Although preoperative imaging is helpful, detection rates are around 50 %.

Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is high risk compared to non-CTO PCI. Iatrogenic coronary artery hematoma formation is a common occurrence during CTO PCI, impairing true lumen visualization. We describe the use of a continuous mechanical suction (CMS) device in 2 applications in which it was used for successful subintimal hematoma decompression and distal vessel re-entry.
