Lacunar
Definition:
(a.) Pertaining to, or having, lacunae; as, a lacunar circulation.
(n.) The ceiling or under surface of any part, especially when it consists of compartments, sunk or hollowed without spaces or bands between the panels.
(n.) One of the sunken panels in such a ceiling.
Example Sentences:
(1) Lacunar infarcts were seen in 21% (37) of the patients with arterial infarcts.
(2) The transversalis fascia of the floor of the femoral canal turns down to form the medial wall of the venous compartment of the femoral sheath, and has the support of the curved edge of the lacunar ligament which effectively bars the femoral canal from entering the thigh.
(3) The eroded and now enlarged lacunar surfaces were lined by newly formed bone and osteoblasts.
(4) These two cases demonstrate that it is not necessary to postulate transient occlusion of the middle cerebral artery as an essential mechanism for progressive lacunar infarction.

(7) Small, deep cerebral infarcts had many of the epidemiological characteristics of other cerebral infarcts but there was a slightly higher frequency of hypertension, significantly lower frequency of a cardiac embolic source, and significantly better survival in patients with lacunar infarction than in those with nonlacunar infarction.
(8) Clinical syndromes, caused by lacunar lesions located either in the supratentorial or in the infratentorial structures, such as pure motor hemiparesis and ataxic hemiparesis were also discussed.
