Even though intravenous thrombolysis with tissue plasminogen activator (IV tPA) is the standard of care in acute ischemic stroke, its use in pregnancy is not clearly defined. Mechanical thrombectomy devices can be an option; however, literature on the use of such mechanical devices in stroke in pregnancy is lacking. Here we describe two cases that developed acute embolic stroke during pregnancy who were successfully treated by mechanical clot retrieval using the Penumbra system 28 (Penumbra Inc., Alameda, California, USA). To the best of our knowledge, these are the only case reports on the use of the Penumbra device in pregnant patients with acute ischemic stroke.

Artery of Percheron infarcts should be considered in the differential diagnosis of patients presenting with sudden alterations in consciousness. MRI should be the investigation of choice. An embolic etiology should be actively looked for.

Immediately after surgical closure of a patent ductus arteriosus, a 12-year-old boy developed severe systemic arterial hypertension refractory to medication. The cause of hypertension could not be found, but it came under control 3 weeks postoperatively with a combination of angiotensin-converting enzyme inhibitor and chlorothiazide.

Pseudoaneurysms are rare lesions secondary to blunt or penetrating trauma, temporomandibular joint surgery, or orthognathic surgery. They are usually produced by arterial breach leading to extravasation of blood. The compressed perivascular tissue forms the wall of aneurysmal sac. This sac gradually expands and can be damaged. Nonsurgical interventions are the treatment of choice for pseudoaneurysms. In the case reported here, emergent endovascular injection of acrylic glue was successful in the treatment of a pseudoaneurysm from a branch of the internal maxillary artery secondary to surgical extraction of impacted maxillary third molar.
