Aims: Iatrogenic occlusive coronary dissection (IOCD) is a rare but high-risk complication of percutaneous coronary intervention (PCI) with limited data on options for management. The aim of this study was to describe a novel approach to the treatment of IOCD in order to gain access to the true coronary lumen. This technique may be feasible in cases in which conventional methods of PCI have failed.
Methods And Results: We performed a retrospective analysis of 11 patients with PCI complicated by IOCD. In all cases, IOCD was treated using the contrast-guided subintimal tracking and re-entry "rescue" (STAR-R) procedure. Angiographic success with TIMI 3 flow was achieved in all patients and stent implantation was performed in 81.8% (n=9). At clinical follow-up (mean 186 ± 79 days), target lesion revascularisation was required in 9% (n=1), with target vessel revascularisation in 27.3% (n=3), and a major adverse cardiac event rate of 27.3% (n=3). Angiographic follow-up was obtained in 81.8% (n=9) with a restenosis rate of 11% (n=1).
Conclusions: The STAR-R procedure is a feasible option for the treatment of IOCD following failure of conventional techniques of treatment.

Iatrogenic arterial injury is an infrequent but limb-threatening complication of total knee arthroplasty (TKA). Open surgical reconstruction may not always be feasible or optimal, particularly in patients who have recently just undergone complex TKA procedures. In this report, we describe the treatment of a patient who developed popliteal artery occlusion following a complex TKA procedure performed the previous day.

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.

Pleomorphic adenoma of the lacrimal gland (PALG) is a benign neoplasm typically presenting with gradual, painless globe displacement and/or lid swelling. We report an atypical case of PALG in a 53-year old male presenting acutely, mimicking orbital cellulitis. Imaging demonstrated an extraconal rim-enhancing soft-tissue lesion medial to the left lacrimal gland, involving superior rectus and levator palpebrae superioris.

The mediastinal vasculature can be affected by various etiologies in cancer patients. Both direct and indirect sequela of cancer may result in life-threatening clinical presentations. Tumor growth may cause vessel narrowing and decreased blood flow from either extrinsic mass effect, invasion into the vascular wall, or tumor thrombus within the lumen.
